We provide a new characterization of implementability of reduced form mechanisms in terms of straightforward second-order stochastic dominance. In addition, we present a simple proof of Matthews’ (1984) conjecture, proved by Border (1991), on implementability.

The U.S. economy hit bottom in June 2009. Thirty months later, output growth remains sluggish and unemployment still hovers above 8%. A critical question is why. One view attributes the weak recovery, at least in part, to high levels of uncertainty about economic policy. This view entails two...

This paper builds on Barreca et al.’s (2013) finding that over the course of the 20th century the proliferation of residential air conditioning led to a remarkable decline in mortality due to extreme temperature days in the United States. Using panel data on monthly mortality rates of...

We empirically analyze the pricing of political uncertainty, guided by a theo- retical model of government policy choice. After deriving the model’s predictions for option prices, we test those predictions in an international sample of national elections and global summits. We find that...

This paper examines how high cost mortgage lending varies by race and ethnicity. It uses a unique panel data that matches a representative sample of mortgages in seven large metropolitan markets between 2004 and 2008 to public records of housing transactions and proprietary credit reporting...

More than half of the variation across U.S. school districts in real K-12 education expenditures per student is due to differences between, rather than within, states. I study the welfare implications of redistribution of education expenditures by the Federal government, using an analytically...

The financial crisis highlighted the importance of systemic risks and of policies that can be employed to prevent and mitigate them. Several recent initiatives aim at establishing institutional frameworks for macro-prudential policy. As this process advances further, substantial uncertainties...

Under what conditions does cost-of-service regulation lead firms to distort costs? This paper analyzes changes in fuel procurement practices by coal- and natural gas-fired electricity generating plants in the United States following state-level legislation that ended cost-of-service regulation...

We assess the consequences of substantially increasing the marginal tax rate on U.S. top earners using a human capital model. We nd that (1) the peak of the model Laer curve occurs at a 52 percent top tax rate, (2) if human capital were exogenous, then the top of the Laer curve would occur at a...

We study the aggregate economic effects of diversity policies such as affirmative action in college admission. If agents are constrained in the side payments they can make, the free market allocation displays excessive segregation relative to the first-best. Affirmative action policies can...
