Affirmative action policies in higher education are used in many countries to try to socially advance historically disadvantaged minorities. Although the underlying social objectives of these policies are rarely criticized, there is intense debate over the actual impact of such preferences in...

This paper builds a tractable partial equilibrium model in the spirit of Melitz (2003), which incorporates two dimensions of heterogeneity: firms specific productivity shocks and firm-market specific demand shocks. The structural parameters of interest are estimated using only cross-sectional...

This paper explains the differential impacts of trade on countries in terms of institutional differences which result in factor market distortions. We modify the Ricardian, Specific Factor and Hecksher Ohlin models of trade to capture these. Trade has both terms of trade effects and output...

This paper studies competition between a small number of suppliers and a single buyer (or an auction with a small number of bidders and a single seller), when total demand (supply) is uncertain. It is well known that when a small number of suppliers compete in supply functions the service is not...

Why are higher quality niches seen as intrinsically more profitable in business circles? Why do high quality products sometimes have a low real price, while it is unusual to see low quality products with high real prices? Can markets have quality differentiation as well as quality bunching? In...

This paper examines the effects of auctioning quota licenses when market power exists. The overall conclusion is that with oligopolistic markets, quotas, even when set optimally and with quota licenses auctioned off, are - unlikely to dominate free trade. Moreover, auction quotas only strictly...

We develop a new model of quality to capture the idea that even if a customer chooses to purchase a product, it may fail to deliver.' In this event, the customer may wish to choose some other product. We model this as a two stage game where firms first choose quality and then price. We find that...

This paper argues that labor market distortions in transition and developing economies help explain differential impacts of trade liberalization. We assume that workers differ in ability. In a market economy their earnings depend on their ability. However, earnings are independent of ability due...

In oligopolistic situations content protection can have unexpected effects as it changes the nature of interactions between input suppliers. With a duoply, it does so in a manner that makes the foreign firm wish to match price increases and decreases of the domestic firm. Domestic input...

Using monthly panel data we solve and estimate, using maximum likelihood techniques, an explicitly dynamic model of criminal behavior where current criminal activity adversely affects future employment outcomes. This acts as 'dynamic deterrence' to crime: the threat of future adverse effects on...
