I consider four policies created to address the financial crisis: (1) the ability-to-repay requirement in mortgage underwriting; (2) reform of rating agency compensation, (3) risk retention in securitization, and (4) mandatory loan renegotiation. I show that according to standard models,...

Prices in government and employer-sponsored health insurance markets only partially reflect insurers' expected costs of coverage for different enrollees. This can create inefficient distortions when consumers self-select into plans. We develop a simple model to study this problem and estimate it...

This paper shows that public provision of private goods may be justified on pure efficiency grounds in an environment where individuals consume both public and private goods. The government's involvement in the provision of private goods provides it with information about individuals' private...

In labor markets, the ratchet effect refers to a situation where workers subject to performance pay choose to restrict their output, because they rationally anticipate that firms will respond to higher output levels by raising output requirements or cutting pay. We model this effect as a...

School choice plans in many cities grant students higher priority for some (but not all) seats at their neighborhood schools. This paper demonstrates how the precedence order, i.e. the order in which different types of seats are filled by applicants, has quantitative effects on distributional...

Understanding potential spillovers from the attributes and actions of neighborhood residents onto the value of surrounding properties and neighborhoods is central to both the theory of urban economics and the development of efficient housing policy. This paper measures the capitalization of...

In a model of evolution driven by conflict between societies more powerful states have an advantage. When the influence of outsiders is small we show that this results in a tendency to hegemony. In a simple example in which institutions differ in their "exclusiveness" we find that these...

FTA bilateral and regional negotiations in Asia have developed quickly in the past decade moving Asia ever closer to an economic union. Unlike Europe with the EU and the 1997 treaty of Rome and the 1993 NAFTA in North American, Asian economic integration does not involve a comprehensive trade...

Environmental quality in many developing countries is poor and generates substantial health and productivity costs. However, existing measures of willingness to pay for environmental quality improvements indicate low valuations by affected households. This paper argues that this seeming paradox...

This paper studies costly network formation in the context of risk sharing. Neighboring agents negotiate agreements as in Stole and Zwiebel (1996), which results in the social surplus being allocated according to the Myerson value. We uncover two types of inefficiency: overinvestment in social...
