Chapter 16 — Further Reading

Foundational works

George Akerlof, "The Market for 'Lemons': Quality Uncertainty and the Market Mechanism," Quarterly Journal of Economics, 1970 The foundational paper on adverse selection. Akerlof shows how information asymmetry can cause market failure in the used-car market. Nobel Prize 2001.

Michael Spence, "Job Market Signaling," Quarterly Journal of Economics, 1973 The foundational paper on signaling. Spence shows how education can function as a credible signal of ability. Nobel Prize 2001.

Joseph Stiglitz and Andrew Weiss, "Credit Rationing in Markets with Imperfect Information," American Economic Review, 1981 Shows how information asymmetry in credit markets leads to credit rationing — banks refuse to lend even to some creditworthy borrowers because they can't distinguish good from bad. Stiglitz Nobel Prize 2001 (with Akerlof and Spence).

Kenneth Arrow, "Uncertainty and the Welfare Economics of Medical Care," American Economic Review, 1963 Cited in Chapter 14 and equally relevant here. Arrow was among the first to identify information asymmetry as a structural feature of healthcare markets.

On the 2008 financial crisis as information failure

Gary Gorton, Slapped by the Invisible Hand: The Panic of 2007, Oxford University Press, 2010 Gorton, a Yale finance professor who had done consulting work on the very financial products that blew up, gives an insider-academic account of the crisis as a "run" on the shadow banking system. The information framework is central.

Michael Lewis, The Big Short: Inside the Doomsday Machine, W. W. Norton, 2010 The most readable account of the crisis, told through the stories of investors who saw it coming. Lewis is a journalist, not an economist, but the narrative captures the information asymmetries vividly. Also a movie.

Andrew Ross Sorkin, Too Big to Fail, Viking, 2009 A blow-by-blow account of the crisis weekend (September 12–15, 2008) when Lehman collapsed and AIG was rescued. Gives you a real-time sense of how the information failures cascaded.

Financial Crisis Inquiry Commission, The Financial Crisis Inquiry Report, 2011 The official U.S. government investigation into the crisis. The report identifies information failures, regulatory failures, and corporate governance failures as contributing causes. Free online.

On reputation systems and the digital economy (case study 2)

Arun Sundararajan, The Sharing Economy: The End of Employment and the Rise of Crowd-Based Capitalism, MIT Press, 2016 A comprehensive treatment of how digital platforms (Uber, Airbnb, TaskRabbit) are reshaping markets. Chapters on reputation systems are particularly relevant.

Chrysanthos Dellarocas, "The Digitization of Word of Mouth: Promise and Challenges of Online Feedback Mechanisms," Management Science, 2003 An early academic paper on how online reputation systems work and where they can fail.

Yanbo Ge, Christopher Knittel, Don MacKenzie, and Stephen Zoepf, "Racial and Gender Discrimination in Transportation Network Companies," NBER Working Paper, 2016 Empirical evidence that ride-hailing ratings can reflect racial and gender bias. Important for understanding the limits of reputation systems.

On contract design and moral hazard

Bengt Holmström, "Moral Hazard and Observability," Bell Journal of Economics, 1979 The foundational paper on designing contracts to address moral hazard. Holmström (Nobel 2016) shows how optimal contracts trade off risk-sharing against incentive provision.

Jean Tirole, The Theory of Corporate Finance, Princeton University Press, 2006 Tirole (Nobel 2014) gives a comprehensive treatment of information problems in corporate finance — including moral hazard, adverse selection, and contract design. Graduate-level but the introduction is accessible.

On insurance economics

Amy Finkelstein, Moral Hazard in Health Insurance, Columbia University Press, 2015 Cited in Chapter 14. Finkelstein's treatment of moral hazard using the Oregon Medicaid experiment is the clearest recent application.

Alma Cohen and Liran Einav, "Estimating Risk Preferences from Deductible Choice," American Economic Review, 2007 An empirical paper on how insurance deductible choices reveal information about risk preferences — a real-world application of screening.

On signaling in education

Bryan Caplan, The Case Against Education: Why the Education System Is a Waste of Time and Money, Princeton University Press, 2018 Caplan argues that the signaling value of education (the credential) is much larger than the human-capital value (what you actually learn). Controversial but well-argued. A useful companion to Spence's signaling model.

Daron Acemoglu and David Autor, "Skills, Tasks and Technologies: Implications for Employment and Earnings," Handbook of Labor Economics, 2011 A comprehensive review of how education, skills, and technology interact in the labor market. More balanced than Caplan on the signaling-vs-human-capital question.

A reading order recommendation

If you have time for one of the sources above, read Akerlof's 1970 paper. It is short (about 20 pages), clearly written, and one of the most important papers in economics. The used-car example is the easiest entry point to information economics.

If you want the financial-crisis application, read Michael Lewis's The Big Short. It's the most engaging account of the crisis and captures the information asymmetries vividly.

If you want the digital-platform application, read Sundararajan's The Sharing Economy.

You have now completed Part III — Markets and Welfare. The five types of market failure (externalities, public goods/commons, distributional failures, healthcare, climate, and information) are all in your toolkit. Part IV — Firm Behavior and Market Structure — begins with Chapter 17: The Costs of Production.
