This dissertation has four chapters. The first three chapters examine health insurance markets in the U.S., focusing in particular on contexts where there are important interactions between health insurance plans. The fourth chapter is on the U.S. budget, examining the implications of annual budget cycles on the quantity and quality of end-of-year spending. Chapter 1, entitled "Bankruptcy as Implicit Health Insurance" examines the interaction between health insurance and the implicit insurance that people have because they can file (or threaten to file) for bankruptcy. With a simple model that captures key institutional features, I demonstrate that the financial risk from medical shocks is capped by the assets that could be seized in bankruptcy. For households with modest seizable assets, this implicit "bankruptcy insurance" can crowd out conventional health insurance. I test these predictions using variation in the state laws that specify the type and level of assets that can be seized in bankruptcy. Because of the differing laws, people who have the same assets and receive the same medical care face different losses in bankruptcy. Exploiting the variation in seizable assets that is orthogonal to wealth and other household characteristics, I show that households with fewer seizable assets are more likely to be uninsured. This finding is consistent with another: uninsured households with fewer seizable assets end up making lower out-of-pocket medical payments. The estimates suggest that if the laws of the least debtor-friendly state of Delaware were applied nationally, 16.3 percent of the uninsured would buy health insurance. Achieving the same increase in coverage would require a premium subsidy of approximately 44.0 percent. To shed light on puzzles in the literature and examine policy counterfactuals, I calibrate a utility-based, micro-simulation model of insurance choice. Among other things, simulations show that "bankruptcy insurance" explains the low take-up of high-deductible health insurance. Chapter 2, entitled "Pricing and Welfare in Health Plan Choice", is coauthored with M. Kate Bundorf and Jonathan Levin. The starting point for the paper is the simple observation that when insurance premiums do not reflect individual differences in expected costs, consumers may choose plans inefficiently. We study this problem in health insurance markets, a setting in which prices often do not incorporate observable differences in expected costs. We develop a simple model and estimate it using data on small employers. In this setting, the welfare loss compared to the feasible risk-rated benchmark is around 2-11% of coverage costs. Three-quarters of this is due to restrictions on risk-rating employee contributions; the rest is due to inefficient contribution choices. Despite the inefficiency, the benefits from plan choice relative to each of the single-plan options are substantial. Chapter 3, entitled "The Private Coverage and Public Costs: Identifying the Effect of Private Supplemental Insurance on Medicare Spending, " is coauthored with Marika Cabral. While most elderly Americans have health insurance coverage through Medicare, traditional Medicare policies leave individuals exposed to significant financial risk. Private supplemental insurance to "fill the gaps" of Medicare, known as Medigap, is very popular. In this Chapter, we estimate the impact of this supplemental insurance on total medical spending using an instrumental variables strategy that leverages discontinuities in Medigap premiums at state boundaries. Our estimates suggest that Medigap increases medical spending by 57 percent--or about 40 percent more than previous estimates. Back-of-the-envelope calculations indicate that a 20 percent tax on premiums would generate combined revenue and savings of 6.2 percent of baseline costs; a Pigovian tax that fully accounts for the fiscal externality would yield savings of 18.1 percent. Chapter 4, entitled "Do Expiring Budgets Lead to Wasteful Year-End Spending? Evidence from Federal Procurement, " is coauthored with Jeffrey Liebman. Many organizations fund their spending out of a fixed budget that expires at year's end. Faced with uncertainty over future spending demands, these organizations have an incentive to build a buffer stock of funds over the front end of the budget cycle. When demand does not materialize, they then rush to spend these funds on lower quality projects at the end of the year. We test these predictions using data on procurement spending by the U.S. federal government. Using data on all federal contracts from 2004 through 2009, we document that spending spikes in all major federal agencies during the 52nd week of the year as the agencies rush to exhaust expiring budget authority. Spending in the last week of the year is 4.9 times higher than the rest-of-the-year weekly average. We examine the relative quality of year-end spending using a newly available dataset that tracks the quality of $130 billion in information technology (I.T.) projects made by federal agencies. Consistent with the model, average project quality falls at the end of the year. Quality scores in the last week of the year are 2.2 to 5.6 times more likely to be below the central value. To explore the impact of allowing agencies to roll unused spending over into subsequent fiscal years, we study the I.T. contracts of an agency with special authority to roll over unused funding. We show that there is only a small end-of-year I.T. spending spike in this agency and that the one major I.T. contract this agency issued in the 52nd week of the year has a quality rating that is well above average.
Industrial Organization in Context examines the economics of markets, industries and their participants and public policy towards these entities. It takes an international approach and incorporates discussion of experimental tests of economic models.
Write clearly about any subject: “Writers should check out Economical Writing, and editors should recommend it. Your future readers will be thankful.” —Journal of Scholarly Publishing Economics is not a field known for good writing. Charts, yes. Sparkling prose, no. Except, that is, when it comes to Deirdre Nansen McCloskey. Her conversational and witty yet always clear style is a hallmark of her classic works of economic history, enlivening the dismal science and engaging readers well beyond the discipline. And now she’s here to share the secrets of how it’s done, no matter what your field. Economical Writing is itself economical: a collection of thirty-five pithy rules for making your writing clear, concise, and effective. Proceeding from big-picture ideas to concrete strategies for improvement at the level of the paragraph, sentence, or word, McCloskey shows us that good writing, after all, is not just a matter of taste—it’s a product of adept intuition and a rigorous revision process. Debunking stale rules, warning us that “footnotes are nests for pedants,” and offering an arsenal of readily applicable tools and methods, she shows writers of all levels of experience how to rethink the way they approach their work, and gives them the knowledge to turn mediocre prose into magic. At once efficient and digestible, hilarious and provocative, Economical Writing lives up to its promise. With McCloskey as our guide, we discover how any piece of writing—on economics or any other subject—can be a pleasure to read.
The past thirty years have witnessed a transformation of government economic intervention in broad segments of industry throughout the world. Many industries historically subject to economic price and entry controls have been largely deregulated, including natural gas, trucking, airlines, and commercial banking. However, recent concerns about market power in restructured electricity markets, airline industry instability amid chronic financial stress, and the challenges created by the repeal of the Glass-Steagall Act, which allowed commercial banks to participate in investment banking, have led to calls for renewed market intervention. Economic Regulation and Its Reform collects research by a group of distinguished scholars who explore these and other issues surrounding government economic intervention. Determining the consequences of such intervention requires a careful assessment of the costs and benefits of imperfect regulation. Moreover, government interventions may take a variety of forms, from relatively nonintrusive performance-based regulations to more aggressive antitrust and competition policies and barriers to entry. This volume introduces the key issues surrounding economic regulation, provides an assessment of the economic effects of regulatory reforms over the past three decades, and examines how these insights bear on some of today’s most significant concerns in regulatory policy.
"Innovation and entrepreneurship are ubiquitous today, both as fields of study and as starting points for conversations among experts in government and economic development. But while these areas on continue to attract public and private investments, many measurements of their resulting economic growth-including productivity growth and business dynamism-have remained modest. Why this difference? Because not all business sectors are the same, and the transformative gains of some industries have been offset by stagnation or contraction in others. Accordingly, a nuanced understanding of the economy requires a nuanced understanding of where innovation and entrepreneurship occur and where they matter. Answering these questions allows for strategic public investment and the infrastructure for economic growth.The Role of Innovation and Entrepreneurship in Economic Growth, the latest entry in the NBER conference series, seeks to codify these answers. The editors leverage industry studies to identify specific examples of productivity improvements enabled by innovation and entrepreneurship, including those from new production technologies, increased competition, new organizational forms, and other means. Taken together, the volume illuminates whether the contribution of innovation and entrepreneurship to economic growth is likely to be concentrated, be it selected sectors or more broadly"--

Essays on Microeconomics and Industrial Organisation aim to serve as a source and work of reference and consultation for the field of Microeconomics in general and of Industrial Organisation in particular. Traditionally, Microeconomics is essentially taught as theory and hardly ever an estimation of a demand, production and cost function is offered . Over the last two decades, however, Microeconomics has greatly broadened its field of empirical application. Therefore, this text combines microeconomic theories with a variety of empirical cases. The standardised microeconomic analysis of demand, production and costs is set forth along with appropriate econometric techniques. The text consists of four parts: Demand, Production and Costs (Supply), Market and Industrial Structure and Failure of Market and Industrial Regulation. It includes eleven new chapters with respect to the first edition.
