The Pennsylvania Liquor Control Board administers the purchase and sale of wine and spirits and is mandated to charge a uniform 30% markup on all products. We use an estimated discrete choice model of demand for spirits, together with information on wholesale prices, to assess the implications...

The Pennsylvania Liquor Control Board administers the purchase and sale of wine and spirits across the state and is legally mandated to charge a uniform 30% markup on all products. We use an estimated discrete choice model of demand for spirits, together with information on wholesale prices, to...

We ask whether incorporating product quality differentiation has real effects on trade flows and welfare. We develop and calibrate a multi-country, general equilibrium model of international trade that includes endogenous product quality differentiation amongst heterogeneous firms. Separable...

IPR policies each period. I use country heterogeneity in education, population, and bilateral trade costs to induce IPR protection choices and firm productivity distributions consistent with the data. I compare the benchmark open economy model to a model without trade and find that the latter...

Empirical literature has largely concluded that increasing intellectual property rights (IPRs) leads to increased trade as firms see the value of their goods (and the ideas embodied in them) increase. These exercises, however, fail to incorporate the changing incentives of developing country...

I study the US semiconductor industry in the context of 1980s legal reform which strengthened intellectual property rights. Prior to the reform, the industry was highly concentrated in a few vertically integrated firms. Post reform, the entry of small design firms led to a fragmented industry...

I study how firms actually compete in nonlinear tariffs by analyzingwhether the incumbent and entrant's decisions to offer a given number oftariff options are interrelated. The goal is to shed some light on thosedynamic and strategic aspects of tariff menus that are currently ignoredby...

This paper uses an equilibrium model of multipart nonlinear pricing to determine the magnitude of foregone profits due to the implementation of simple tariff options. I then use the available information from a cross-section of independent cellular telephone markets to study how these foregone...
