Master Outline — Introductory Economics

This document is the master scaffolding for the entire textbook. Every chapter entry below is the source of truth for what that chapter must cover, what its learning objectives are, what its concept budget is, which anchor examples and themes it draws on, and roughly how long it should be. It is read at the top of every generation session and consulted whenever a chapter is being written.

Total: 40 chapters across 9 content parts + 1 capstone.

Part I — Thinking Like an Economist (4 chapters)

The mindset before the models. By the end of this part, the reader has a vocabulary for what they already do every day and a sense that economics is a way of seeing — not a body of conclusions to memorize.

Chapter 1 — What Is Economics? Scarcity, Choice, and the Thinking That Changes Everything

Word budget: 10,000–11,000 (foundational chapter; allow more) Anchor: Millbrook (intro vignette: a student deciding between a job and a study group) Themes: Tradeoffs (foundational), Incentives, Behavioral preview, Affects daily life

Learning objectives: 1. Define economics as the study of how people make choices under scarcity, and explain why scarcity is universal. 2. Apply opportunity cost to a real personal decision and compute the cost in non-monetary terms. 3. Distinguish marginal thinking from all-or-nothing thinking, and explain why economic decisions are made at the margin. 4. Identify how incentives shape behavior in three contexts: a consumer, a firm, and a policy.

Concept budget (10–12 terms): scarcity, opportunity cost, marginal cost, marginal benefit, incentive, tradeoff, sunk cost, rational choice, positive vs. normative, economic way of thinking, model (preview), the lens metaphor

Coverage summary: Open with a relatable choice — the reader deciding between studying and going out — and use it to introduce opportunity cost as something they already know intuitively. Build the four foundational ideas: scarcity is universal, every choice has an opportunity cost, decisions happen at the margin, people respond to incentives. Use Millbrook State University as an early concrete setting (the dorm cafeteria deciding what to serve, the bookstore choosing between expanding textbooks or merchandise). Close with the economic way of thinking as a lens — it reveals some things brilliantly and obscures others. This framing is honest about the limits of economics from page one.

Chapter 2 — How Economists Think: Models, Assumptions, and the Art of Simplification

Word budget: 9,000–10,000 Anchor: Theoretical examples — model use of all four anchors Themes: Disagreement (foundational), Data tells stories, Tradeoffs (modeling tradeoffs)

Learning objectives: 1. Explain why economists use models and what makes a model useful versus misleading. 2. Read and interpret the production possibilities frontier and the circular flow diagram. 3. Distinguish positive economics (what is) from normative economics (what should be). 4. Identify three reasons economists disagree, and apply them to a current policy debate.

Concept budget (10–12): model, assumption, production possibilities frontier, circular flow, positive economics, normative economics, ceteris paribus, economic profit vs. accounting profit (preview), efficiency, equity, growth, comparative statics

Coverage summary: Why we model. The PPF as the simplest economic model. The circular flow as a map of where money and goods come from. Useful simplifications versus dangerous distortions — the "spherical cow" problem. Positive vs. normative — and why the distinction matters even though everyone violates it. The four reasons economists disagree: different values, different models, different evidence, different time horizons. This chapter sets up the intellectual honesty that runs through the whole book: models are useful tools, not truth-claims.

Chapter 3 — Interdependence and the Gains from Trade: Why Specialization Makes Everyone Richer

Word budget: 9,500–10,500 Anchor: Millbrook (Riverside Foods plant) Themes: Tradeoffs, Markets power+imperfect, Affects daily life

Learning objectives: 1. Distinguish absolute advantage from comparative advantage with a numerical example. 2. Calculate gains from trade for two parties using opportunity costs. 3. Explain why trade benefits both parties even when one is better at everything. 4. Apply comparative advantage to a real-world example (a household, a firm, or two countries).

Concept budget (10–12): absolute advantage, comparative advantage, opportunity cost (revisited), specialization, gains from trade, terms of trade, autarky, division of labor, productivity (preview), trade-off frontier

Coverage summary: Why you don't grow your own food. Why doctors hire cleaners. Why a country with terrible factories still trades with a country with great ones. Build comparative advantage from a clean numerical example (two people, two goods) and then scale to the country level. Use Millbrook's Riverside Foods plant as a concrete example of specialization and trade — the plant doesn't make every food product Millbrook consumes; it specializes in frozen vegetables for a regional market and trades for everything else. The chapter ends with a preview of Chapter 9's deeper treatment of international trade.

Chapter 4 — How to Read Economic Data: Numbers, Charts, and the Stories They Tell (and Hide)

Word budget: 10,000–11,000 (Mankiw doesn't have this chapter; ours is distinctive) Anchor: COVID economy (FRED series) Themes: Data tells stories (foundational), Affects daily life, Disagreement (about what data show)

Learning objectives: 1. Read a Bureau of Labor Statistics jobs report and identify the three numbers that journalists usually misrepresent. 2. Interpret a Consumer Price Index release and explain why people's lived experience often diverges from the official rate. 3. Look up a real economic series on FRED and produce a basic comparison (current vs. historical, US vs. peer country). 4. Identify three common ways economic charts are misleading (truncated axes, cherry-picked dates, scale tricks).

Concept budget (10–12): time series, index, base year, percent change, year-over-year, seasonally adjusted, FRED, BLS, BEA, Census Bureau, headline vs. core, real vs. nominal

Coverage summary: This is the chapter Mankiw doesn't have. Walk through the actual layout of a BLS jobs report. Walk through the actual layout of a CPI release. Walk through the FRED interface. Show three real misleading charts (truncated y-axis, cherry-picked endpoints, log vs. linear) and explain what they hide. Anchor with COVID-era data because the recovery story looks dramatically different on different chart designs. This chapter makes the reader data-literate before they hit Part II's technical content. It's also the chapter that sets up every "Data Literacy" sidebar in subsequent chapters.

Part II — How Markets Work: Microeconomic Foundations (6 chapters)

The price system as a coordination mechanism. By the end of this part, the reader can predict what happens to price and quantity when conditions change in any market — and they understand that markets are powerful but not magical.

Chapter 5 — Supply and Demand: The Most Powerful Model in Economics

Word budget: 11,000–12,000 (THE foundational chapter — generous budget) Anchor: Millbrook (housing near MSU) Themes: Markets power+imperfect (foundational), Tradeoffs, Incentives, Affects daily life

Learning objectives: 1. Construct a demand curve for a real good and identify the five shifters of demand. 2. Construct a supply curve for a real good and identify the five shifters of supply. 3. Find market equilibrium graphically and algebraically, given simple supply and demand equations. 4. Predict the direction (and qualitative magnitude) of price and quantity changes when one or more shifters move.

Concept budget (12–15): demand curve, supply curve, law of demand, law of supply, ceteris paribus, equilibrium price, equilibrium quantity, shifters of demand, shifters of supply, surplus, shortage, movement along vs. shift of, substitutes, complements, normal goods, inferior goods

Coverage summary: Build the supply-and-demand model from intuition: why demand slopes down (diminishing marginal benefit, substitution, income effect — the latter two get a sidebar), why supply slopes up (increasing marginal cost). Show the equilibrium concept as a coordination mechanism, not a "law" of nature. Walk through five worked examples of shifts (gas prices spike, students graduate, a new factory opens, a recession hits, a substitute appears). Use Millbrook housing as the anchor example: rents rise; what happened? Was it a demand shift (more students, MSU enrollment up) or a supply shift (a developer pulled out of a project)? The diagnostic exercise of figuring out which shifted is the chapter's central skill.

Chapter 6 — Elasticity: How Responsive Are Buyers and Sellers?

Word budget: 9,500–10,500 Anchor: Minimum wage (labor demand elasticity) Themes: Tradeoffs, Incentives, Data tells stories (elasticity estimates)

Learning objectives: 1. Calculate price elasticity of demand using the midpoint formula and interpret elastic, inelastic, and unit-elastic results. 2. Identify four determinants of demand elasticity and predict elasticities for unfamiliar goods. 3. Apply elasticity to determine who bears the burden of a tax or subsidy. 4. Distinguish income elasticity from price elasticity and use both to classify goods.

Concept budget (10–12): elasticity, price elasticity of demand, price elasticity of supply, midpoint formula, elastic, inelastic, unit elastic, perfectly elastic, perfectly inelastic, income elasticity, cross-price elasticity, tax incidence (preview)

Coverage summary: Why demand for insulin is inelastic and demand for restaurant meals is elastic. The four determinants: substitutes, necessity vs. luxury, time horizon, share of budget. The geometry of elasticity along a linear demand curve. Tax incidence as a preview of Chapter 7. Use the labor market and the minimum wage debate as the running example: how elastic is labor demand? If labor demand is inelastic, a minimum wage causes few job losses; if elastic, many. The empirical answer matters and is contested — preview Card-Krueger.

Chapter 7 — Government Intervention: Price Controls, Taxes, and Subsidies

Word budget: 10,500–11,500 Anchor: Millbrook (rent control proposal); Minimum wage (price floor) Themes: Markets power+imperfect, Tradeoffs, Disagreement, Behavioral

Learning objectives: 1. Draw a price ceiling and a price floor on a supply-and-demand diagram and identify the resulting shortage or surplus. 2. Explain why economists overwhelmingly oppose rent control as written but voters often support it — and evaluate both perspectives. 3. Calculate tax incidence and explain why who pays the tax depends on elasticity, not on who writes the check. 4. Define deadweight loss and explain why it's a measure of inefficiency, not a measure of how bad a policy is.

Concept budget (10–12): price ceiling, price floor, binding price control, shortage, surplus, deadweight loss, tax incidence, statutory vs. economic incidence, subsidy, rent control, minimum wage, behavioral lens (why voters support what economists oppose)

Coverage summary: Rent control is the most controversial policy in economics — present both sides honestly. The standard model shows why rent control reduces supply long-term. The behavioral and political lens shows why voters facing a rent bill don't care about the long-term supply curve. Both responses make sense. Then minimum wage as a price floor — and the empirical evidence (Card-Krueger and successors) showing the standard model's prediction is too strong at modest wage floors. Tax incidence: introduce the elastic-side-bears-less rule. Use the proposed Millbrook rent control ordinance as the anchor — students debate the ordinance using both the standard model and the behavioral framing.

Chapter 8 — Consumer and Producer Surplus: Measuring the Gains from Trade

Word budget: 9,000–10,000 Anchor: Millbrook (housing welfare) Themes: Markets power+imperfect, Tradeoffs (efficiency vs. equity)

Learning objectives: 1. Define and calculate consumer surplus and producer surplus from a supply-and-demand diagram. 2. Show graphically how a price ceiling, price floor, or tax affects total surplus and creates deadweight loss. 3. Distinguish economic efficiency from economic equity and explain why an "efficient" outcome can be unfair. 4. Apply surplus analysis to a real policy (a tax, a subsidy, or a price control).

Concept budget (10–12): consumer surplus, producer surplus, total surplus, willingness to pay, willingness to sell, market efficiency, allocative efficiency, deadweight loss (revisited), efficiency-equity tradeoff, Pareto improvement, Pareto efficiency, social welfare

Coverage summary: Surplus as a numerical measure of who gains how much from a market. The visual: consumer surplus is the triangle above price and below the demand curve; producer surplus is the triangle below price and above the supply curve. A tax shifts these areas and creates a triangle of pure loss — deadweight loss. The efficiency-equity tradeoff is the chapter's central tension: a market can be efficient and still produce outcomes most people consider unfair. This sets up Part III's whole exploration of when markets fail. Use Millbrook housing again: who gains and who loses when rents are controlled? When subsidized? When unregulated? Each policy has a different surplus distribution.

Chapter 9 — International Trade: Comparative Advantage in a Global Economy

Word budget: 10,000–11,000 Anchor: Millbrook (Riverside Foods exports) Themes: Tradeoffs, Markets power+imperfect, Disagreement (about trade), Affects daily life

Learning objectives: 1. Apply comparative advantage to two countries and predict the pattern of trade. 2. Show graphically how a tariff affects domestic consumers, domestic producers, and government revenue. 3. Identify the winners and losers from trade and explain why trade increases total wealth without distributing gains equally. 4. Evaluate the political economy of trade — why economists support free trade and many voters oppose it, and what each side is responding to.

Concept budget (10–12): comparative advantage (revisited), tariff, quota, trade agreement, world price, import, export, terms of trade, China shock, distributional effect, free trade, protectionism

Coverage summary: From the two-person comparative-advantage model to two countries trading. What a tariff does on a supply-and-demand diagram (raises domestic price, helps domestic producers, hurts domestic consumers, generates government revenue, creates two deadweight loss triangles). Then the political economy: free trade increases total wealth, but the gains and losses are not evenly distributed — and the losers are concentrated, visible, and angry, while the winners are diffuse and quiet. The China shock (Autor-Dorn-Hanson) is presented as a real, documented effect — economists were wrong to dismiss the local labor-market damage of trade with China. Use Millbrook's Riverside Foods plant: it exports frozen vegetables to Canada and Mexico and competes against imports from Brazil. The plant's fortunes depend on the trade regime.

Chapter 10 — Behavioral Economics: Why People Don't Always Act the Way the Model Predicts

Word budget: 10,500–11,500 (full chapter, not a sidebar) Anchor: COVID (savings during pandemic) Themes: Behavioral (foundational — this is the chapter), Disagreement, Tradeoffs

Learning objectives: 1. Identify five common cognitive biases (loss aversion, present bias, anchoring, status quo bias, framing) with real examples. 2. Apply prospect theory to a decision and explain how it differs from expected utility theory. 3. Distinguish a "nudge" from a mandate and identify the ethical questions nudging raises. 4. Apply behavioral lens to a standard economic prediction and evaluate whether the prediction holds.

Concept budget (12–14): rationality (preview), bounded rationality, prospect theory, loss aversion, reference point, present bias, hyperbolic discounting, anchoring, status quo bias, framing effect, nudge, default, choice architecture, social preferences

Coverage summary: The neoclassical assumption of rationality — useful but often wrong. Walk through Kahneman and Tversky's experiments. Loss aversion (losses hurt about twice as much as equivalent gains feel good). Present bias (why people don't save enough for retirement). Anchoring (why "originally $100, now $40" works on you). Status quo bias (why automatic enrollment in retirement plans dramatically increases participation). Framing (why "90% lean" sells better than "10% fat"). Then nudges: Thaler and Sunstein's idea that designing choice architecture can help people make better decisions without restricting freedom. The ethical questions: who decides what's "better"? Use COVID-era savings spike as a contemporary example: people saved much more than the standard model predicted because they couldn't spend, not because they suddenly became patient — and unwound those savings in 2021–22 in ways that helped fuel inflation.

The chapter ends by giving the reader a behavioral lens they will use for the rest of the book. From Chapter 11 forward, every chapter has a "Behavioral Lens" callout: does the standard prediction hold here? Where does it miss?

Part III — Markets and Welfare: When Markets Work and When They Don't (6 chapters)

Markets fail in predictable ways. By the end of this part, the reader can identify the four main types of market failure (externalities, public goods, information asymmetries, distributional concerns) and evaluate proposed remedies.

Chapter 11 — Externalities: When Your Choices Affect Others Who Didn't Choose

Word budget: 10,000–11,000 Anchor: Millbrook (Walden Creek pollution) Themes: Markets power+imperfect, Tradeoffs, Behavioral, Affects daily life

Learning objectives: 1. Distinguish negative and positive externalities and identify three real examples of each. 2. Show graphically why a market with a negative externality produces too much of the good and a market with a positive externality produces too little. 3. Compare four solutions to externalities (Pigouvian taxes, cap-and-trade, regulation, Coase theorem) and identify when each works best. 4. Apply the Coase theorem to a low-transaction-cost dispute and explain why it fails for high-transaction-cost problems like climate change.

Concept budget (10–12): externality, negative externality, positive externality, social cost, social benefit, private cost, private benefit, Pigouvian tax, cap-and-trade, Coase theorem, transaction cost, market failure

Coverage summary: Externalities are the simplest market failure — when my choices affect you and you didn't choose. Build the social-cost-vs.-private-cost graph carefully. Walk through four solutions: Pigouvian taxes (a tax equal to the marginal external cost), cap-and-trade (limit total quantity, allow trading), regulation (mandate technology or behavior), and the Coase theorem (private bargaining when transaction costs are low). Each solution has tradeoffs. Use the Walden Creek pollution case as the anchor: a small chemical plant upstream from a recreational fishing area. Show how each remedy would work in this concrete case. Climate change as a preview of Chapter 15 — the largest externality in human history, and one where transaction costs make Coase bargaining impossible.

Chapter 12 — Public Goods and Common Resources: The Free Rider and the Tragedy of the Commons

Word budget: 9,500–10,500 Anchor: Millbrook (downtown parking garage proposal) Themes: Markets power+imperfect, Tradeoffs, Disagreement (about Ostrom)

Learning objectives: 1. Classify a good as private, public, common-pool, or club using the rivalry/excludability matrix. 2. Explain the free-rider problem and why it makes markets unable to provide public goods efficiently. 3. Apply the tragedy of the commons to a real example (overfishing, traffic, groundwater). 4. Evaluate Elinor Ostrom's design principles for managing commons without privatization or government control.

Concept budget (10–12): rival, non-rival, excludable, non-excludable, private good, public good, common-pool resource, club good, free rider, tragedy of the commons, Ostrom's design principles, collective action

Coverage summary: The 2x2 matrix of rivalry and excludability — and the four resulting categories. The free rider problem: why I'd happily benefit from your contribution to national defense without contributing myself. The tragedy of the commons: why fisheries collapse, why traffic congests, why aquifers drain. Then Elinor Ostrom — Nobel laureate, political scientist, demolisher of the simplest "commons → tragedy" story. Her work shows commons can be managed sustainably without privatization or government, but only under specific conditions. Walk through her design principles. Use Millbrook's proposed downtown parking garage as the anchor: Is parking a public good (non-rival, non-excludable)? A common resource (rival, non-excludable)? A club good? The answer depends on how it's designed and priced.

Chapter 13 — The Economics of Inequality: Who Gets What and Why

Word budget: 11,000–12,000 (large topic) Anchor: Millbrook (MSU adjunct wage gap), Minimum wage, 2008 (asset recovery), COVID (K-shaped recovery) Themes: Tradeoffs (efficiency vs equity), Disagreement (causes and cures), Markets power+imperfect, Affects daily life

Learning objectives: 1. Construct and interpret a Lorenz curve and calculate a Gini coefficient. 2. Identify the four leading explanations for rising inequality since 1980 (skill-biased technical change, globalization, institutional change, winner-take-all markets) and evaluate the evidence for each. 3. Compare three philosophical frameworks for evaluating inequality (utilitarian, Rawlsian, libertarian). 4. Evaluate four anti-poverty policies (cash transfers, EITC, minimum wage, education) using both economic and ethical criteria.

Concept budget (12–14): Lorenz curve, Gini coefficient, income inequality, wealth inequality, skill-biased technical change, globalization, winner-take-all markets, EITC, cash transfer, minimum wage (revisited), Piketty's r > g, intergenerational mobility, utilitarian, Rawlsian, libertarian

Coverage summary: What inequality looks like (measured), why it has risen in most rich countries since 1980 (debated), what philosophical frameworks help us evaluate it (multiple legitimate perspectives), what policies might address it (each with tradeoffs). Be honest about the empirical disputes (Auten-Splinter critique of Piketty) and the philosophical disputes (the libertarian framing is presented fairly). Use the MSU adjunct wage gap as the anchor — adjunct faculty at Millbrook State earn ~$3,000 per course, while tenure-track faculty earn $80,000+ for similar teaching loads. This is the inequality the reader can see in their own classroom. Connect to 2008 (asset-holders recovered fast; wage-earners did not), COVID (the K-shaped recovery), and the minimum wage debate as one piece of the inequality story.

Chapter 14 — The Economics of Healthcare: Why the Market for Medicine Doesn't Work Like the Market for Pizza

Word budget: 10,500–11,500 Anchor: COVID (essential workers, healthcare strain) Themes: Markets power+imperfect, Tradeoffs, Disagreement (about systems), Affects daily life

Learning objectives: 1. Explain three reasons healthcare doesn't behave like a normal market (information asymmetry, moral hazard, adverse selection). 2. Compare four healthcare systems (US mixed, UK single-payer, Canada, Singapore) on cost, outcomes, and access. 3. Apply economic reasoning to a real US healthcare debate (drug pricing, Medicare for All, ACA, surprise billing). 4. Identify three ways the US system spends more and gets less than peer countries, and three reasons that's politically hard to change.

Concept budget (10–12): information asymmetry, moral hazard, adverse selection, principal-agent problem, third-party payer, single-payer, multi-payer, mixed system, Medicare, Medicaid, ACA, drug pricing

Coverage summary: Why healthcare is the market failure Americans experience most personally. Information asymmetry — you don't know what treatment you need; the doctor does. Moral hazard — once insured, you consume more healthcare than you'd pay out-of-pocket for. Adverse selection — sick people want insurance more than healthy people, so insurance pools skew sick. Walk through the four systems comparatively: US mixed, UK single-payer, Canada, Singapore. Be specific about tradeoffs — no system has solved this. The US spends ~17% of GDP on healthcare (peer countries spend 9–11%) and gets worse outcomes on most measures. Why? Higher prices (not more services), administrative complexity, and political fragmentation. Use COVID as the anchor: the pandemic exposed both the strengths (rapid vaccine development, treatment innovation) and weaknesses (uneven access, frontline worker strain, cost crisis) of the US system simultaneously.

Chapter 15 — The Economics of the Environment and Climate Change

Word budget: 11,000–12,000 (defining 21st-century challenge) Anchor: Climate change as global externality Themes: Markets power+imperfect, Tradeoffs, Disagreement (Stern vs. Nordhaus), Behavioral

Learning objectives: 1. Apply externality analysis to climate change and identify three reasons it's the hardest externality problem in history. 2. Compare carbon tax, cap-and-trade, and regulation approaches to climate policy. 3. Explain the discount rate problem and why the Stern-Nordhaus debate produces different policy conclusions from the same physics. 4. Evaluate "green industrial policy" and the political economy of just transition.

Concept budget (12–14): climate change, greenhouse gases, social cost of carbon, discount rate, Stern Review, Nordhaus DICE model, carbon tax, cap-and-trade, carbon border adjustment, stranded asset, just transition, green industrial policy, IRA (Inflation Reduction Act), Paris Agreement

Coverage summary: The defining economic challenge of the 21st century. Climate change as the largest externality in human history — global, intertemporal, irreversible. Apply Chapter 11's framework but at much greater scale. The discount rate problem: how much should we sacrifice now for future generations? Stern (low discount rate, urgent action) vs. Nordhaus (higher discount rate, more gradual action). Both economists are honest; the disagreement is about ethics, not arithmetic. Carbon pricing as the consensus mechanism (~90% of economists support a price on carbon). Cap-and-trade vs. carbon tax — pros and cons of each. Green industrial policy (the IRA's bet that subsidizing clean tech can substitute for direct carbon pricing in a politically constrained environment). The just transition: workers in coal towns are real people facing real economic dislocation, and economic policy that ignores them generates political backlash that ends climate policy.

Chapter 16 — Information Asymmetry, Adverse Selection, and the Markets That Almost Don't Work [NEW]

Word budget: 10,000–11,000 Anchor: 2008 (mortgage-backed securities, AIG) Themes: Markets power+imperfect, Disagreement, Affects daily life

Learning objectives: 1. Distinguish adverse selection from moral hazard with concrete examples and explain why each unravels markets in different ways. 2. Apply the lemons model (Akerlof) to a real market (used cars, used housing, freelance hires). 3. Identify three signaling mechanisms markets use to overcome adverse selection (warranties, education credentials, reputation systems). 4. Explain how mortgage-backed securities and AIG's CDS positions illustrated information failures in the run-up to 2008.

Concept budget (10–12): asymmetric information, adverse selection, moral hazard, lemons problem (Akerlof), signaling, screening, principal-agent, contract design, deductible, warranty, reputation system, CDS (credit default swap)

Coverage summary: This is the new chapter added to Part III. Information failures are a fourth distinct kind of market failure — separate from externalities, public goods, and inequality, though they interact with all three. Build adverse selection from Akerlof's used-car model. Build moral hazard from insurance examples. Show how markets find partial workarounds: warranties (signal quality), education credentials (signal type), reputation systems (Yelp, eBay, Uber star ratings — and their limitations). Then 2008 as the anchor: mortgage-backed securities were a market design that deliberately obscured information about underlying loan quality, and AIG's credit default swap positions were insurance contracts whose adverse selection problem brought down the company. Information failures don't just inconvenience markets — they can take down whole financial systems.

Part IV — Firm Behavior and Market Structure (5 chapters)

How firms make decisions and how the structure of a market shapes those decisions. By the end of this part, the reader can analyze any firm's pricing decision and identify what kind of market it operates in.

Chapter 17 — The Costs of Production: How Firms Think About Costs

Word budget: 9,500–10,500 Anchor: Millbrook (Riverside Foods cost structure) Themes: Tradeoffs, Incentives, Affects daily life

Learning objectives: 1. Distinguish total, fixed, variable, average, and marginal cost — and graph each correctly. 2. Explain why the marginal cost curve is U-shaped (diminishing returns) and how it relates to the average cost curve. 3. Distinguish short-run from long-run costs and explain economies of scale. 4. Apply cost analysis to a real firm decision (whether to expand, whether to shut down, whether to enter a market).

Concept budget (12–14): total cost, fixed cost, variable cost, average total cost, average fixed cost, average variable cost, marginal cost, production function, marginal product, diminishing returns, economies of scale, diseconomies of scale, sunk cost, short run vs. long run

Coverage summary: What firms actually think about. Build cost curves carefully — every shape has a reason. Diminishing returns explains the upward slope of marginal cost. Economies of scale explain the downward slope of long-run average cost (over some range). The relationship between marginal cost and average cost (when marginal pulls average down, then pushes it up). Sunk costs are sunk — a key behavioral insight that surprisingly many firms violate. Use Riverside Foods as the running example: walk through its actual cost structure (rough, illustrative numbers). What's fixed (the plant, the equipment, salaried managers)? What's variable (line workers, electricity, raw vegetables)? What does its long-run average cost curve look like? When would it shut down a production line? When would it expand?

Chapter 18 — Perfect Competition: The Benchmark Model

Word budget: 10,000–11,000 Anchor: Millbrook (regional agricultural markets) Themes: Markets power+imperfect, Tradeoffs

Learning objectives: 1. Identify the four assumptions of perfect competition and explain why no real market satisfies all of them. 2. Show why a competitive firm produces where marginal revenue equals marginal cost. 3. Distinguish short-run equilibrium (positive economic profit possible) from long-run equilibrium (zero economic profit). 4. Apply perfect competition as a benchmark to a real market and identify how that market deviates from the benchmark.

Concept budget (10–12): perfect competition, price taker, marginal revenue, profit maximization (MR = MC), economic profit, accounting profit, short-run equilibrium, long-run equilibrium, free entry and exit, barriers to entry (preview), benchmark model

Coverage summary: Perfect competition is a benchmark, not a description. Build it from the four assumptions (many firms, identical products, free entry/exit, perfect information). The key result: in long-run equilibrium, economic profit is zero — and that's not as bad as it sounds, because economic profit is profit above the opportunity cost of the resources. Use regional agricultural markets near Millbrook as the closest real-world approximation — many farmers, similar corn and soybeans, free entry/exit (slow but real), well-developed price information. Then compare to a market that's clearly not competitive (say, the local cable monopoly or the monopolistic-competition restaurant scene). The benchmark is useful precisely because it tells us what we're comparing real markets to.

Chapter 19 — Monopoly: When One Firm Controls the Market

Word budget: 10,000–11,000 Anchor: Big Tech (contemporary monopoly debate) Themes: Markets power+imperfect, Tradeoffs, Disagreement (about big tech), Affects daily life

Learning objectives: 1. Identify four sources of monopoly power (legal barriers, natural monopoly, network effects, control of inputs) and give examples of each. 2. Show graphically how a monopolist sets quantity and price, and calculate the deadweight loss. 3. Distinguish first-, second-, and third-degree price discrimination and identify real examples. 4. Evaluate whether contemporary tech firms (Google, Apple, Amazon, Meta) qualify as monopolies — and what (if anything) should be done.

Concept budget (12–14): monopoly, market power, barrier to entry, natural monopoly, network effect, patent, monopoly profit, deadweight loss of monopoly, price discrimination, first-degree, second-degree, third-degree, antitrust, Sherman Act, Clayton Act

Coverage summary: Why some markets have one dominant firm and what to do about it. The four sources of monopoly power. The monopolist's problem: choosing quantity to maximize profit (which means producing where MR = MC, but charging the price the demand curve allows at that quantity — a price above marginal cost). The deadweight loss from monopoly. Price discrimination as a way to capture more surplus, with real examples (airline pricing, student discounts, bulk discounts, software pricing tiers). Then the contemporary tech monopoly question: are Google, Apple, Amazon, and Meta actually monopolies in the legal sense? The answer is contested. Walk through arguments on both sides honestly. Antitrust enforcement has historically used the consumer welfare standard (low prices = no harm), and tech firms often offer free or low-cost services. The question is whether that standard captures all the relevant harms.

Chapter 20 — Monopolistic Competition and Oligopoly: The Messy Middle

Word budget: 10,000–11,000 Anchor: Millbrook (restaurant scene); airlines/cellular as oligopoly examples Themes: Markets power+imperfect, Tradeoffs, Behavioral, Affects daily life

Learning objectives: 1. Distinguish monopolistic competition from oligopoly and identify real examples of each. 2. Show short-run and long-run equilibrium for a monopolistically competitive firm. 3. Apply game theory (specifically the prisoner's dilemma and Nash equilibrium) to an oligopoly pricing decision. 4. Explain why cartels are unstable even when they would benefit all members.

Concept budget (12–14): monopolistic competition, oligopoly, product differentiation, advertising, brand value, short-run equilibrium, long-run equilibrium, game theory, payoff matrix, dominant strategy, Nash equilibrium, prisoner's dilemma, cartel, collusion, OPEC

Coverage summary: Most real markets aren't perfectly competitive or pure monopoly — they're somewhere in the middle. Monopolistic competition (many firms, differentiated products): the Millbrook restaurant scene, the local clothing stores, the app stores' apps. Each has some pricing power because their product is unique, but free entry drives long-run economic profit to zero. Oligopoly (few firms, strategic interaction): airlines, wireless carriers, soft drinks, search engines. Game theory becomes essential because firms' decisions depend on what they expect each other to do. Build the prisoner's dilemma carefully and show why it explains cartel instability — every member has an incentive to defect. OPEC as a real (and partially successful) cartel that has spent decades fighting the prisoner's dilemma. Use Millbrook's restaurant scene as the recurring monopolistic-competition example: dozens of restaurants, no two identical, free entry over the medium term, modest economic profit at any given moment because new entrants are always nipping at the heels of successful incumbents.

Chapter 21 — Labor Markets: The Economics of Working and Earning

Word budget: 11,000–12,000 (large topic, deep treatment) Anchor: Millbrook (local labor market, MSU adjuncts), Minimum wage (full treatment) Themes: Markets power+imperfect, Tradeoffs, Disagreement, Behavioral, Affects daily life

Learning objectives: 1. Derive labor demand from the marginal revenue product of labor and labor supply from the work-leisure tradeoff. 2. Apply the model to wage determination in a competitive labor market and identify when monopsony power changes the prediction. 3. Explain four sources of wage variation (human capital, compensating differentials, discrimination, market power) and evaluate evidence for each. 4. Synthesize the minimum wage debate across the chapter's tools: supply and demand, elasticity, monopsony, behavioral, empirical evidence.

Concept budget (14–16): labor demand, labor supply, marginal product of labor, marginal revenue product, work-leisure tradeoff, human capital, compensating differential, discrimination, monopsony, union, collective bargaining, minimum wage, labor force participation, unemployment (preview Ch 24), gig economy, automation

Coverage summary: The labor market is the most important market in most readers' lives — it pays for everything else. Build the standard model carefully: labor demand from marginal revenue product, labor supply from the work-leisure tradeoff. Wage determination in a competitive market. Then complications: human capital (education, training, experience explain a lot of wage variation), compensating differentials (dangerous jobs pay more), discrimination (theory and empirical evidence), and monopsony power (when employers have wage-setting power, the standard prediction reverses for minimum wage and other interventions). The chapter is the place where the minimum wage debate gets the deepest treatment in the book — pulling together supply-and-demand (Ch 5), elasticity (Ch 6), price floors (Ch 7), and the behavioral lens (Ch 10). Then automation and AI: which jobs are at risk (the empirical evidence is more nuanced than headlines suggest), and what history teaches about technological unemployment (it has always existed in the short run but rarely in the long run — though the short run can last decades for displaced workers). The gig economy as a contemporary case: flexibility for some, precarity for others, and the regulatory mess of trying to fit it into 20th-century labor categories.

Part V — Macroeconomic Foundations (4 chapters)

What is the "economy" and how do we measure it? By the end of this part, the reader can read a GDP report, a CPI release, and a jobs report — and they understand the basic framework for thinking about why some countries are rich and others are poor.

Chapter 22 — Measuring the Economy: GDP, and What It Misses

Word budget: 10,000–11,000 Anchor: COVID (GDP contraction and recovery) Themes: Data tells stories, Markets power+imperfect, Affects daily life

Learning objectives: 1. Calculate GDP using both the expenditure approach (C + I + G + NX) and the income approach. 2. Distinguish real from nominal GDP and use the GDP deflator to convert between them. 3. Identify three things GDP measures well (market production) and three things it misses (unpaid labor, environmental costs, inequality). 4. Compare GDP to alternative measures of national wellbeing (HDI, Genuine Progress Indicator, subjective wellbeing).

Concept budget (12–14): GDP, real GDP, nominal GDP, GDP deflator, expenditure approach, income approach, C + I + G + NX, consumption, investment, government purchases, net exports, GDP per capita, HDI, Genuine Progress Indicator

Coverage summary: What GDP is, how it's calculated, what it captures, and what it misses. Build the expenditure identity carefully. Real vs. nominal — and why the distinction matters during inflation. GDP per capita as a measure of average living standards (with caveats — averages hide distributions). What GDP misses: unpaid household labor, leisure, environmental degradation, distributional concerns, the underground economy, much of the digital economy. Alternative measures: HDI, GPI, life satisfaction surveys. Use the COVID economy as the anchor: GDP fell sharply in Q2 2020 (the worst quarterly drop in modern history), then recovered faster than any postwar recession — but the recovery was uneven, and GDP didn't capture the value of pandemic-era informal childcare or the cost of pandemic-era loneliness. End with a how-to-read-a-GDP-release walkthrough.

Chapter 23 — The Cost of Living: Inflation, CPI, and Why Your Grandparents' Prices Were Lower

Word budget: 10,000–11,000 Anchor: Millbrook (cost of living), COVID (2021–23 inflation) Themes: Data tells stories, Affects daily life, Disagreement (CPI biases)

Learning objectives: 1. Explain how the Consumer Price Index is constructed and identify three biases in its measurement (substitution, new goods, quality change). 2. Calculate inflation rates and convert nominal values to real values using a price index. 3. Distinguish core from headline inflation and explain why central banks watch core. 4. Analyze the costs of inflation (and deflation) and identify who benefits and who is hurt by each.

Concept budget (12–14): Consumer Price Index, basket of goods, base year, inflation rate, core inflation, headline inflation, real vs. nominal, substitution bias, new goods bias, quality bias, deflation, hyperinflation, indexed contract, indexation

Coverage summary: What inflation is, how it's measured, why measurement is hard. Walk through CPI construction: a fixed basket of goods, priced repeatedly. The three biases: substitution (consumers switch when prices rise; the fixed basket doesn't), new goods (smartphones didn't exist in 1990's basket), quality (a 2025 car is far better than a 1990 car at the same price). The PCE deflator as the alternative the Fed prefers. Why core inflation (excluding food and energy) is what central banks target. The costs of inflation: shoe-leather, menu costs, redistribution from creditors to debtors, tax distortions, uncertainty. The costs of deflation: debt burden, delayed spending, the zero lower bound (preview Ch 27). Hyperinflation case studies: Weimar Germany, Zimbabwe, Venezuela. Then the 2021–23 inflation episode: cost-push (supply chain) vs. demand-pull (stimulus) vs. expectations-driven — present three explanations honestly. Use Millbrook's cost-of-living story: groceries, rent, gas — what really got more expensive between 2020 and 2024, and how that affected an average Millbrook household.

Chapter 24 — Unemployment: Why People Who Want Jobs Can't Find Them

Word budget: 10,000–11,000 Anchor: Millbrook (Riverside Foods layoffs), COVID, 2008 Themes: Markets power+imperfect, Tradeoffs, Affects daily life

Learning objectives: 1. Explain how the Bureau of Labor Statistics measures unemployment and identify three groups the official rate misses. 2. Distinguish frictional, structural, and cyclical unemployment and identify policy responses appropriate to each. 3. Define the natural rate of unemployment (NAIRU) and explain why economists believe it changes over time. 4. Apply unemployment analysis to a real episode (the 2008 recession, the COVID recession, the long-term unemployment problem).

Concept budget (12–14): labor force, unemployment rate, labor force participation rate, frictional unemployment, structural unemployment, cyclical unemployment, natural rate of unemployment, NAIRU, discouraged worker, U-3, U-6, long-term unemployment, unemployment insurance, hysteresis

Coverage summary: Walk through how the BLS measures unemployment (the Current Population Survey, the household survey, the employer survey). Three types: frictional (between jobs), structural (skills mismatch), cyclical (recession). The natural rate is the sum of frictional and structural — and is non-zero even in a "good" economy. Why the rate has fallen over time (better job matching, more flexible labor markets) and why it might rise again (skill polarization, AI displacement). Long-term unemployment is qualitatively different from short-term — hysteresis effects mean a long unemployment spell makes future employment harder. Racial disparities: Black unemployment has been roughly 2× white unemployment for decades, with little change. Use the Riverside Foods plant as the anchor — when the plant closed a production line in 2019, who was unemployed, what type of unemployment was it, and what happened to those workers? Then 2008 (cyclical unemployment, slow recovery, hysteresis) and COVID (the weirdest unemployment episode — a massive spike followed by a near-record-fast recovery, but with a lasting drop in labor force participation). End with a how-to-read-a-jobs-report walkthrough.

Chapter 25 — Economic Growth: Why Some Countries Are Rich and Others Are Poor

Word budget: 11,000–12,000 (the most important question in economics) Anchor: Cross-country comparisons; East Asian miracle; African growth Themes: Tradeoffs, Disagreement (growth causes), Affects daily life

Learning objectives: 1. Apply the Rule of 70 to compute doubling times for different growth rates and demonstrate the long-run power of compounding. 2. Identify the four sources of growth in the production function (physical capital, human capital, natural resources, technology) and rank their importance from empirical evidence. 3. Explain Acemoglu and Robinson's institutional theory of growth and evaluate its evidence. 4. Apply growth analysis to a real country (the East Asian miracle, Botswana, Haiti, Argentina) and identify what worked or didn't.

Concept budget (12–14): economic growth, real GDP per capita, production function, physical capital, human capital, natural resources, technology, total factor productivity, Solow model, conditional convergence, institutions (inclusive vs. extractive), property rights, rule of law

Coverage summary: The most important question in economics. Why South Korea is rich and Ghana is not — and why the answer is harder than the simple stories suggest. Build the Rule of 70 carefully (a 2% growth rate doubles in 35 years; a 7% rate doubles in 10). Walk through the production function intuitively (Solow model in the advanced sidebar, intuition only in the main text). Why physical capital is the easiest source to add (and why it has diminishing returns). Why human capital is harder. Why technology matters most in the long run. Then institutions — Acemoglu and Robinson's "Why Nations Fail" thesis, with both supporting evidence (cross-country regressions, natural experiments like North vs. South Korea) and the critiques (institutions are endogenous, the empirical work is contested). The East Asian miracle as a case where rapid growth succeeded; sub-Saharan Africa as a case where it has struggled; Botswana as a sub-Saharan exception. Argentina as the tragic case of de-development. End with the convergence debate: are poor countries catching up? Some are; some aren't. Why?

Part VI — Money, Banking, and Monetary Policy (4 chapters)

The plumbing of the modern economy. By the end of this part, the reader understands what money is, what banks do, and how the Federal Reserve tries to steer the economy.

Chapter 26 — Money and Banking: What Money Is and Why Banks Are Fragile

Word budget: 10,000–11,000 Anchor: 2008 (Lehman, shadow banking) Themes: Markets power+imperfect, Behavioral (bank runs), Affects daily life

Learning objectives: 1. Identify the three functions of money and use them to evaluate whether something (cryptocurrency, gold, dollars, frequent flyer miles) qualifies as money. 2. Explain how fractional reserve banking creates money through the money multiplier. 3. Describe the structure of the Federal Reserve System and explain its dual mandate. 4. Apply the Diamond-Dybvig model intuitively to explain why bank runs happen and how deposit insurance addresses them.

Concept budget (12–14): money, medium of exchange, unit of account, store of value, commodity money, fiat money, fractional reserve banking, money multiplier, M1, M2, central bank, Federal Reserve, dual mandate, bank run, deposit insurance, FDIC

Coverage summary: What is money? The three functions test, applied to historical and contemporary candidates. The history: barter → commodity money (gold, silver) → representative money (gold-backed paper) → fiat money (dollars backed by trust in the government). How banks create money — the fractional reserve framework, with the multiplier as a simplified example. The Federal Reserve System — its structure (12 regional banks, the Board of Governors, the FOMC), its independence (and the historical reasons for it), its dual mandate (maximum employment and stable prices). Why banks are fragile: the Diamond-Dybvig model intuitively. Deposit insurance as a solution (and the moral hazard it creates). Then 2008 as the anchor: shadow banking — the parts of the financial system that did banking-like things without being formally regulated as banks — experienced a modern bank run when short-term funding markets froze. This is the chapter where the reader first sees that 2008 was, in important ways, a 21st-century bank run.

Chapter 27 — Monetary Policy: How the Fed Tries to Steer the Economy

Word budget: 11,000–12,000 Anchor: 2008 response, COVID response, 2022–23 rate hikes Themes: Disagreement, Tradeoffs, Affects daily life

Learning objectives: 1. Identify the Fed's main policy tools (federal funds rate, open market operations, IOER, discount rate, reserve requirements) and explain how each works. 2. Trace the transmission mechanism from a Fed rate change to economic outcomes (borrowing, spending, output, employment, inflation). 3. Explain quantitative easing — what it is, when it's used, and the evidence about whether it works. 4. Apply monetary policy analysis to the 2008 response, the COVID response, and the 2022–23 rate hike cycle.

Concept budget (12–14): monetary policy, federal funds rate, open market operations, IOER (interest on excess reserves), discount rate, reserve requirement, transmission mechanism, expansionary policy, contractionary policy, quantitative easing, forward guidance, zero lower bound, Taylor Rule

Coverage summary: The Fed's tools. The transmission mechanism: rate → borrowing cost → consumer and business spending → output → employment and inflation. Why the Fed's job is hard: long and variable lags, imperfect data, the dual mandate's tension when inflation is high and unemployment is high. The Taylor Rule as a description (and a normative benchmark). Quantitative easing — what it is (large-scale asset purchases), when it was used (after the 2008 zero lower bound, then again in COVID), and the evidence about whether it worked (mixed and contested). Forward guidance. The 2022–23 rate hike cycle: the most aggressive tightening since Volcker. Did it work? The textbook answer: yes, inflation fell substantially without a sharp recession — surprising most forecasters, including the Fed. The interpretation is contested: was it good policy, good luck, post-pandemic supply chain healing, or all three? Where economists disagree: rules vs. discretion, the Phillips curve trade-off, whether the Fed should target inflation or nominal GDP, whether monetary policy is too powerful or not powerful enough.

Chapter 28 — The Financial System: Saving, Investment, and the Loanable Funds Market

Word budget: 9,500–10,500 Anchor: 2008, COVID Themes: Markets power+imperfect, Affects daily life

Learning objectives: 1. Apply the loanable funds model to explain how saving and investment determine the real interest rate. 2. Show graphically how a government budget deficit affects the loanable funds market (crowding out, with caveats). 3. Distinguish bank-based from market-based financial intermediation and identify the role of stocks, bonds, and derivatives. 4. Evaluate the efficient market hypothesis and explain what it claims, what evidence supports it, and where it breaks down.

Concept budget (12–14): loanable funds, saving, investment, real interest rate, nominal interest rate, crowding out, financial intermediation, bond, stock, equity, dividend, risk premium, diversification, efficient market hypothesis

Coverage summary: The market for borrowing and lending. Build the loanable funds model: saving is supply, investment is demand, the price is the real interest rate. Government deficits as additional demand for funds — crowding out as a possible consequence (with the qualification that crowding out is small at the zero lower bound). Financial intermediation: banks vs. bond markets vs. stock markets. Risk and return — why a stock that's expected to lose money sometimes still attracts buyers (the risk premium). Diversification as the one true free lunch in finance. The efficient market hypothesis: weak form (past prices don't predict future), semi-strong form (public information is priced in), strong form (even private information is priced in). Evidence is mixed; weak and semi-strong have substantial support, strong is contested. Why your uncle who "beats the market" is probably either lucky or charging you fees. Connect to 2008 (a crisis caused by financial system failure) and to personal finance — index funds, retirement accounts, the 401(k). This chapter is also where the book pairs naturally with the (hypothetical) DataField Personal Finance textbook.

Chapter 29 — Inflation: Causes, Consequences, and the Central Bank's Dilemma

Word budget: 10,000–11,000 Anchor: COVID (2021–23 episode), 2008 (deflation risk) Themes: Disagreement, Data tells stories, Affects daily life

Learning objectives: 1. State the quantity theory of money (MV = PY) and use it to explain the long-run relationship between money growth and inflation. 2. Distinguish demand-pull from cost-push inflation and identify which dominated in three historical episodes (1970s stagflation, 2008 deflation scare, 2021–23 surge). 3. Explain the role of inflation expectations and why a central bank's credibility matters more than its tools. 4. Apply the short-run Phillips curve and explain why it isn't a stable long-run relationship.

Concept budget (12–14): quantity theory of money, MV = PY, velocity, demand-pull inflation, cost-push inflation, expectations, anchored expectations, Phillips curve, short-run Phillips curve, long-run Phillips curve, NAIRU (revisited), Volcker disinflation, anchoring (revisited)

Coverage summary: Inflation in depth. Quantity theory as the long-run anchor: in the long run, sustained money growth in excess of output growth produces sustained inflation. But "the long run" is not the only run that matters. Short-run inflation can be driven by demand (too much spending chasing too few goods) or by supply (input costs rising). Most real episodes involve both. Inflation expectations matter because they're self-fulfilling: if everyone expects 5% inflation, wages and prices adjust to deliver it. The Phillips curve as a short-run relationship between inflation and unemployment — and the famous failure of the long-run version when expectations adjust. The Volcker disinflation: the most dramatic monetary policy experiment in US history (rates above 20% in 1981, deep recession, but inflation fell from 13% to 4% in three years and stayed low for forty years). The 2021–23 inflation surge: was it transitory, was it persistent, what fixed it? Three honest answers; the debate is still live.

Part VII — Macroeconomic Fluctuations and Policy (4 chapters)

Booms, busts, and what governments can (and can't) do about them. By the end of this part, the reader can analyze a recession using the AS-AD model and understand the tools and limits of fiscal and monetary policy.

Chapter 30 — The Business Cycle: Why Economies Boom and Bust

Word budget: 10,000–11,000 Anchor: 2008 (Great Recession), COVID Themes: Markets power+imperfect, Disagreement, Affects daily life

Learning objectives: 1. Identify the four phases of the business cycle and three indicators that signal each. 2. Distinguish demand shocks from supply shocks and identify three real examples of each. 3. Explain why the 2008 Great Recession was a different kind of recession from a typical postwar slump. 4. Explain why the COVID recession was unique in modern history.

Concept budget (10–12): business cycle, expansion, peak, recession, trough, leading indicator, lagging indicator, coincident indicator, demand shock, supply shock, NBER (National Bureau of Economic Research), Great Moderation, Great Recession, COVID recession

Coverage summary: Recessions happen. Why? Demand shocks (financial crises, pandemics, sudden drops in consumer confidence) versus supply shocks (oil prices, natural disasters, supply chain disruptions). Why some recessions are deep (1929, 2008) and others are shallow (1990, 2001). The "Great Moderation" thesis from the 1990s: economists thought we had figured out how to dampen business cycles. The 2008 Great Recession demolished that confidence. Walk through 2008 as a case study: what made it different from a typical recession (a financial crisis at its core, not just a slowdown). Then COVID as another case study: a recession with no precedent (not financial, not driven by Fed tightening, not gradual — a sudden shutdown of the service economy by public health policy). Two recessions, two completely different mechanisms, both within fifteen years. Be honest about how this should chasten anyone's confidence about predicting the next one.

Chapter 31 — Aggregate Demand and Aggregate Supply: The Macroeconomic Model

Word budget: 11,000–12,000 (key macro model) Anchor: COVID (simultaneous demand and supply shocks) Themes: Markets power+imperfect, Disagreement (Keynesian vs. classical), Tradeoffs

Learning objectives: 1. Build the aggregate demand curve and identify three reasons it slopes downward (wealth effect, interest rate effect, exchange rate effect). 2. Distinguish short-run aggregate supply from long-run aggregate supply and explain why the SRAS slopes upward. 3. Use the AS-AD model to analyze a demand shock, a supply shock, and a stagflation scenario. 4. Evaluate the Keynesian vs. classical debate about whether economies self-correct in the long run, and explain why "the long run" is the central question.

Concept budget (12–14): aggregate demand, aggregate supply, short-run aggregate supply, long-run aggregate supply, wealth effect, interest rate effect, exchange rate effect, output gap, potential output, recessionary gap, inflationary gap, stagflation, self-correcting mechanism, classical vs. Keynesian

Coverage summary: The standard macroeconomic model — the closest thing macro has to a single unifying framework. Build the AD curve carefully (three reasons for the downward slope). Build SRAS and LRAS. Use the model to walk through a demand shock (right-shift of AD: output up, prices up; left-shift: output down, prices down) and a supply shock (right-shift of SRAS: output up, prices down; left-shift: output down, prices up — stagflation). The Keynesian vs. classical debate becomes concrete here: classicals think the economy self-corrects to full employment in the long run; Keynesians think the long run can be very long ("in the long run we are all dead"). Both are right under different conditions — the question is which conditions apply now. Use COVID as the anchor: 2020 was a simultaneous demand shock (people stuck at home spending less on services) and supply shock (factories closed, supply chains disrupted). Standard models had a hard time with it because most models assume one shock at a time.

Chapter 32 — Fiscal Policy: Government Spending, Taxes, and the Deficit

Word budget: 11,000–12,000 Anchor: 2008 (ARRA), COVID (CARES Act, ARP), Millbrook (federal exposure) Themes: Disagreement (multipliers, austerity), Tradeoffs, Affects daily life

Learning objectives: 1. Distinguish automatic stabilizers from discretionary fiscal policy and identify which works faster. 2. Apply the multiplier concept to a stimulus or tax cut, and explain why empirical multiplier estimates vary widely. 3. Explain the relationship between deficits, debt, and crowding out — and identify when crowding out is small vs. large. 4. Evaluate the austerity debate and the lessons from the Reinhart-Rogoff error.

Concept budget (12–14): fiscal policy, government spending, taxes, transfer payment, automatic stabilizer, discretionary policy, deficit, debt, debt-to-GDP, crowding out, multiplier, marginal propensity to consume, ARRA, CARES Act, Reinhart-Rogoff

Coverage summary: What governments do with spending and taxes to influence the economy. Automatic stabilizers (progressive taxes, unemployment insurance) work without legislation and are typically the fastest acting. Discretionary policy (stimulus packages, tax cuts) works through legislation and is slower. The multiplier: a dollar of government spending can generate more than a dollar of GDP (if MPC is high) — and empirical estimates vary from below 1 to above 2 depending on conditions. Be honest about this range; the size of the multiplier is one of the most contested numbers in macroeconomics. Then debt and deficits: the national debt is large and rising; what does that mean? When does it matter? Crowding out is the standard mechanism — government borrowing competes with private borrowing for funds, raising interest rates and reducing private investment — but the mechanism is weak at the zero lower bound. The 2009 ARRA stimulus and the 2020–21 COVID packages as case studies — the political economy of each, the empirical evidence about their effects. The austerity debate: did European austerity in 2010–13 hurt or help? The Reinhart-Rogoff "90% debt threshold" claim and its famous coding-error retraction — and what we learn about the fragility of empirical economic claims.

Chapter 33 — The Open Economy: Trade, Capital Flows, and Exchange Rates

Word budget: 10,000–11,000 Anchor: Currency crises, dollar's reserve status Themes: Markets power+imperfect, Disagreement, Affects daily life

Learning objectives: 1. Apply the balance of payments framework and explain the relationship between the current account and the capital account. 2. Determine an exchange rate using supply-and-demand for currencies and identify three things that can shift each curve. 3. Distinguish fixed from floating exchange rate regimes and identify the trilemma (exchange rate, capital mobility, monetary independence). 4. Apply open-economy analysis to a real episode (the Asian financial crisis, the eurozone crisis, China's exchange rate policy).

Concept budget (12–14): balance of payments, current account, capital account, exchange rate, appreciation, depreciation, fixed exchange rate, floating exchange rate, purchasing power parity, Mundell-Fleming, trilemma, currency crisis, reserve currency, dollarization

Coverage summary: Open-economy macro. The balance of payments identity. Exchange rate determination (markets for currencies). Fixed vs. floating regimes — and the impossible trinity (a country can have any two of: fixed exchange rate, free capital mobility, independent monetary policy — but not all three). Mundell-Fleming intuition (the math is in the advanced sidebar). The Asian financial crisis (1997) as a currency crisis that taught the world about contagion and capital flow reversals. The eurozone (1999–present) as a monetary union with no fiscal union — and the design flaws that surfaced in the 2010–13 crisis. China's exchange rate policy: what they did, why, and why the US complained for two decades. The dollar's role as the world's reserve currency: what it gives the US (cheap borrowing, geopolitical leverage) and what it costs (a permanently overvalued currency that hurts exporters).

Part VIII — Contemporary Economics (5 chapters)

The topics most textbooks don't cover. By the end of this part, the reader has the economic vocabulary to discuss AI and labor, the housing crisis, cryptocurrency, global poverty, and the question of what economics can and can't say about the good life.

Chapter 34 — Development Economics: Poverty, Aid, and the World's Poorest Countries [NEW]

Word budget: 11,000–12,000 Anchor: Cross-country development examples (Bangladesh, Rwanda, Haiti, India) Themes: Tradeoffs, Disagreement (about aid), Affects daily life (global perspective)

Learning objectives: 1. Distinguish absolute from relative poverty and explain how the World Bank defines extreme poverty. 2. Identify three theories of underdevelopment (geography, institutions, colonial history) and evaluate the evidence for each. 3. Compare aid-based, trade-based, and institution-based development strategies — and identify what works and what hasn't. 4. Apply randomized controlled trial methodology (Banerjee, Duflo, Kremer) to a real development question.

Concept budget (12–14): absolute poverty, relative poverty, extreme poverty, World Bank, development trap, geography hypothesis, institutions hypothesis, colonial legacy, foreign aid, microfinance, conditional cash transfer, RCT (randomized controlled trial), J-PAL, Millennium Development Goals, SDGs

Coverage summary: This is the new chapter added to Part VIII. Why a textbook for global readers can't leave development economics to a footnote in the growth chapter. Walk through poverty measurement: extreme poverty (defined by the World Bank at $2.15/day, 2017 PPP) has fallen dramatically since 1990, but progress has slowed and reversed in some places. Three theories of underdevelopment: geography (Sachs), institutions (Acemoglu & Robinson, revisited from Ch 25), colonial history (a historian's lens that economists used to dismiss and increasingly take seriously). Foreign aid: does it work? The honest answer is "sometimes, in some forms, for some purposes." Walk through the Sachs-Easterly debate. Then the RCT revolution: Banerjee, Duflo, and Kremer winning the 2019 Nobel for taking development questions to randomized field experiments. What works (deworming, conditional cash transfers, some microfinance). What doesn't (some heavily promoted programs failed RCT scrutiny). End with case studies: Bangladesh's improbable rise, Rwanda's complicated success, Haiti's persistent struggles, India's mixed record.

Chapter 35 — The Economics of Technology: AI, Platforms, and the Digital Economy

Word budget: 10,500–11,500 Anchor: Millbrook (Innovation Hub), AI labor market debate Themes: Markets power+imperfect, Disagreement (about AI), Tradeoffs, Affects daily life

Learning objectives: 1. Apply network effects to explain why platform markets tend toward winner-take-all outcomes. 2. Distinguish two-sided markets from one-sided markets and identify three real examples. 3. Evaluate three claims about AI and labor markets (mass unemployment, augmentation, polarization) using the empirical evidence. 4. Apply economic reasoning to the gig economy and identify the regulatory question it raises.

Concept budget (12–14): network effect, platform, two-sided market, multi-sided market, winner-take-all, data as input, marginal cost (digital), zero marginal cost, gig economy, classification (employee vs. contractor), AI, automation, technological unemployment, complementarity vs. substitution

Coverage summary: Modern technology has features the standard supply-and-demand model handles awkwardly. Network effects — the value of being on Facebook depends on how many other people are on Facebook — drive winner-take-all market structures. Two-sided markets (Uber connecting drivers and riders, Amazon connecting sellers and buyers) have pricing dynamics that look strange to traditional market analysis (sometimes one side is subsidized to attract the other). Digital goods have near-zero marginal cost, which makes pricing them strange. The gig economy as a regulatory puzzle: are gig workers employees, contractors, or something new? Each answer has tradeoffs. AI and labor: the most contested contemporary topic. Walk through three claims honestly: (1) AI will cause mass unemployment, (2) AI will mostly augment human labor, (3) AI will polarize labor markets (helping high-skill workers, displacing middle-skill workers). The empirical evidence so far supports (3) more than (1), but the time horizon matters and the technology is moving fast. End with Millbrook's Innovation Hub — a public-private incubator that just opened on the edge of campus, betting on AI/data science startups. What does the success of the hub depend on? Network effects, talent supply, capital, regulation, luck.

Chapter 36 — The Economics of Student Debt, Housing, and the American Dream Under Pressure

Word budget: 11,000–12,000 Anchor: Millbrook (housing crunch), COVID (housing shock) Themes: Markets power+imperfect, Tradeoffs, Disagreement, Affects daily life

Learning objectives: 1. Identify four explanations for college cost growth (Baumol's cost disease, Bennett hypothesis, administrative bloat, state funding cuts) and evaluate the evidence for each. 2. Apply cost-benefit analysis to "is college worth it?" and identify the conditions under which it isn't. 3. Apply supply-and-demand analysis to housing affordability and identify why supply restrictions are the central problem. 4. Compare three policy responses to housing affordability (zoning reform, rent control, subsidies) and identify their tradeoffs.

Concept budget (12–14): college cost disease, Baumol's cost disease, Bennett hypothesis, administrative bloat, student debt, return to college, NIMBY, zoning, exclusionary zoning, housing affordability, supply restriction, missing middle, rent control (revisited), housing voucher

Coverage summary: The economics of being young in 2025 vs. 1975 — and why the American Dream feels harder to achieve. College: tuition has risen far faster than inflation for forty years. Four explanations, all partially true. Baumol's cost disease (services with stagnant productivity get more expensive relative to manufactured goods). The Bennett hypothesis (federal aid lets colleges raise prices). Administrative bloat (real, but contested in magnitude). State funding cuts (a major factor at public universities). Is college worth it? On average, yes — college graduates still earn substantially more over a lifetime. But the variance is huge, the debt loads are real, and the marginal student (the one who would not have gone without expanded access) sees a much smaller return than the average. Then housing: why have housing prices outpaced wages? The supply-side answer: zoning, NIMBYism, and the missing middle (no construction of mid-density housing in most metropolitan areas). The demand-side answer: low interest rates pushing prices up. Both matter; the supply side matters more in the long run. Three policy responses (zoning reform, rent control, vouchers) with their tradeoffs. Use Millbrook as the anchor: the student housing crunch around MSU, the city's 2024 zoning reform debate, and the COVID-era price surge that priced out many residents.

Chapter 37 — Cryptocurrency, Digital Currency, and the Future of Money

Word budget: 10,000–11,000 Anchor: Bitcoin, stablecoins, CBDCs Themes: Markets power+imperfect, Disagreement (about crypto), Behavioral, Affects daily life

Learning objectives: 1. Apply the three-functions-of-money test to Bitcoin and evaluate whether it qualifies as money. 2. Distinguish Bitcoin from stablecoins from central bank digital currencies (CBDCs) and identify the design choices each makes. 3. Explain the monetary theory implications of private money and identify three historical episodes of private money. 4. Evaluate two claims about crypto (it's revolutionary; it's a Ponzi scheme) and articulate the more nuanced reality.

Concept budget (12–14): Bitcoin, blockchain, mining, decentralization, stablecoin, fiat-backed stablecoin, algorithmic stablecoin, CBDC (central bank digital currency), private money, free banking era, monetary theory, Hayek, gold standard

Coverage summary: Cryptocurrency from an economics perspective — not a tech perspective. Bitcoin as a monetary experiment. Apply the functions-of-money test: is it a medium of exchange? (Sometimes, for some things, expensively.) Is it a unit of account? (Almost never — almost no one prices things in Bitcoin.) Is it a store of value? (Volatile, but historically yes for early holders.) Conclusion: Bitcoin is a speculative asset more than money, but the line is blurry. Stablecoins (Tether, USDC) as a different beast — backed by traditional assets, used heavily for crypto trading. Central bank digital currencies (China's e-CNY, the ECB's digital euro project) as still another beast. The history of private money: the US "free banking era" (1837–1864) when many private banks issued their own notes, with mixed results. Hayek's Denationalization of Money (1976) as the intellectual ancestor of crypto's libertarian wing. The honest economic assessment: crypto has demonstrated some real innovations (programmable money, censorship-resistant payments) and some real failures (volatility, fraud, environmental cost, persistent association with criminal use). It is neither a revolution nor a Ponzi scheme — it is a new asset class still figuring out what it's for.

Chapter 38 — Economics and the Good Life: What Economic Thinking Can and Cannot Tell You

Word budget: 10,000–11,000 (philosophical capstone for content) Anchor: General — synthesizing Themes: Tradeoffs, Disagreement, Behavioral, Affects daily life

Learning objectives: 1. Apply the Easterlin paradox to the relationship between income and happiness, and identify what the empirical research really says. 2. Identify three things markets do well and three things they do poorly, using examples from earlier chapters. 3. Distinguish economic efficiency from human flourishing and explain why one doesn't reduce to the other. 4. Articulate a personal stance on how to use economic thinking with but not instead of other ways of thinking.

Concept budget (10–12): Easterlin paradox, hedonic adaptation, happiness economics, life satisfaction, capability approach (Sen), subjective well-being, GDP critique (revisited), efficiency vs. flourishing, ethics, citizenship, the good life

Coverage summary: The book's most reflective chapter. Economics is powerful — and limited. The Easterlin paradox: above a moderate income, more money doesn't seem to make people much happier on most measures (though the most recent research suggests the paradox is weaker than it once looked). Hedonic adaptation: humans get used to almost anything, both good and bad. Sen's capability approach as an alternative framework — what matters is what people are able to do and be, not just what they consume. The book takes a clear position: economic thinking is a powerful tool for analyzing tradeoffs, incentives, and unintended consequences — and using it as the only lens for evaluating policy or personal life is a mistake. This isn't a critique of economics; it's a defense of economics done with humility. The reader's job, going forward, is to think economically and to think morally, historically, ethically, and aesthetically. None of those should crowd out the others. End by previewing the synthesis chapters.

Part IX — Synthesis (2 chapters)

The book's closing pair. The first maps the actual state of consensus and disagreement in economics; the second tells the reader what to do with what they have learned.

Chapter 39 — Where Economists Agree and Where They Don't: An Honest Map of the Debate

Word budget: 10,500–11,500 Anchor: All four (this is the synthesis chapter) Themes: Disagreement (foundational to chapter), all others

Learning objectives: 1. Identify three areas of strong economic consensus (free trade, opposition to rent control, support for carbon pricing) and the IGM Forum survey data behind them. 2. Identify three areas of genuine economic disagreement (optimal minimum wage, fiscal multiplier size, role of government) and explain why the disagreement persists. 3. Distinguish disagreement about facts (evidence is incomplete) from disagreement about values (different ethical frameworks). 4. Apply the honest-debate framing to a contemporary policy controversy of the reader's choosing.

Concept budget (10–12): consensus, IGM Forum, expert survey, consensus building, methodological pluralism, ideology, evidence, prediction, replication, the dismal-pluralism

Coverage summary: Map the actual landscape of agreement and disagreement among professional economists, using IGM Forum poll data wherever possible. Strong consensus: free trade increases total wealth (~85% agree), rent control as written reduces housing supply (~95%), carbon pricing is the most efficient climate tool (~90%), the gold standard would be bad (~95%). Real disagreement: the right minimum wage, the size of fiscal multipliers, the optimal top tax rate, the right monetary rule, the right approach to inequality, the role of regulation in tech. Distinguish factual disagreement (we don't know yet — more evidence needed) from value disagreement (we want different things). The reader should leave with a sense that economics is a serious discipline with real findings AND a discipline where intelligent practitioners genuinely disagree about important questions. Both can be true. They are.

Chapter 40 — Economics as a Superpower: How to Use What You've Learned

Word budget: 9,000–10,000 (closing chapter; lyrical) Anchor: Capstone preview (Millbrook) Themes: All seven (closing synthesis)

Learning objectives: 1. Apply economic thinking to a personal financial decision (a job offer, a major purchase, a debt question). 2. Apply economic thinking to a political claim and identify the tradeoffs the claim is hiding. 3. Identify three places to go next (intermediate micro, intermediate macro, econometrics, behavioral, development, applied fields). 4. Articulate the reader's own position on the most important economic question of their lifetime.

Concept budget (10–12): economic literacy, civic literacy, personal finance, opportunity cost (revisited), tradeoffs (revisited), incentives (revisited), behavioral lens (revisited), data literacy (revisited), thinking on the margin, pluralism, lifelong learning

Coverage summary: The book's closing chapter. Not new content — application. How to use economic thinking in your life. The personal: a job offer, a major purchase, student debt, retirement savings, a career change. The political: how to read a campaign promise, how to evaluate a tax proposal, how to spot a misleading economic claim. The civic: voting on economic policy, attending a town meeting, participating in the kinds of debates Millbrook holds about its zoning ordinance. What to read next. Where to go for ongoing economic literacy (FRED, BLS, IGM Forum, the better economics blogs and podcasts). Then a closing benediction: economics is not about the economy. It is about how to think about tradeoffs, incentives, and unintended consequences. That skill applies to everything. Use it carefully. Use it humbly. But use it. The book ends with a preview of the capstone project — Build an Economic Analysis of Your City — and the line: "The mountains of evidence in this book matter only if you do something with them. Now go do something."

Part X — Capstone Project (5 files)

The capstone is Build an Economic Analysis of Your City — a 20–30 page deliverable that progresses across the entire book. The capstone files in part-10-capstone/ are the student-facing instructions for each phase.

• _part-intro.md — overview of the capstone, the deliverable specification, the timeline, and the Millbrook example as a model
• capstone-project-01.md — Microeconomic analysis (Parts I–IV applied to your city: scarcity, markets, market failures, firm behavior, labor)
• capstone-project-02.md — Macroeconomic analysis (Parts V–VII applied to your city: GDP/employment/inflation, money/banking, fiscal/monetary exposure)
• capstone-project-03.md — Synthesis and policy recommendation (Parts VIII–IX applied: what does your city face going forward, and what would you recommend?)
• capstone-rubric.md — the 20–30 page deliverable rubric

Notes

• Sequencing: Chapters must be written in order. Forward dependencies are heavy (Chapter 5 is foundational to everything; Chapter 10 establishes the behavioral lens used from Chapter 11 onward; Chapter 31 builds on Chapters 22–30).
• Anchor distribution: every chapter must touch ≥1 anchor. The matrix in _continuity.md tracks this.
• Themes distribution: each chapter should reinforce 2–3 of the seven themes. The themes matrix in _continuity.md tracks this.
• Disagreements: the contested-claims inventory in _continuity.md is the source of truth for how each contested claim should be framed across chapters.
• Tone: match the voice samples in _continuity.md.
• Accessibility: every graph requires a plain-English caption AND a 100–200 word text description. Use Mermaid for flowcharts, ASCII/Unicode for supply-demand crosses.
