A firm's productivity depends on how production is organized given the level of demand for its product. To capture this mechanism, we develop a theory of an economy where firms with heterogeneous demands use labor and knowledge to produce. Entrepreneurs decide the number of layers of management...

Many new exporters give up exporting very shortly, despite substantial entry costs; others shoot up foreign sales and expand to new destinations. We develop a model based on experimentation to rationalize these and other dynamic patterns of exporting firms. We posit that individual export...

We examine the qualitative and quantitative predictions of a heterogeneous firm model à la Melitz (2003) in the context of the Canada - US Free Trade Agreement (CUSFTA) of 1989. We calibrate our model to the pre-trade liberalization stage, simulate the trade liberalization, and compute the...

When trade costs are of the iceberg type (Samuelson 1952) and markups are independent of trade costs, relative prices across markets are distorted, but relative prices within markets are not. When trade costs depart from the analytically convenient iceberg type, distortion will also occur within...

This paper reviews the implications of the Uruguay Round Government Procurement Agreement, both for current practice in the United States and for general conditions of market access in other major markets. We emphasize the relative importance of government purchases within given markets. Because...

The paper examines why ‘globaphobia’ seems to be more prevalent among labour in the United States than in Europe. It argues that globalization has generated more wealth, but also more income inequality and adjustment problems, in America than in Europe. In the United States, the median voter...

We find that trade unions have a rational incentive to oppose the adoption of labour-saving technology when labour demand is inelastic and unions care much for employment relative to wages. Trade liberalization typically increases trade union technology opposition. These conclusions are reached...

Recent theoretical work predicts that an important margin of adjustment to deregulation or trade reforms is the reallocation of output within firms through changes in their product mix. Empirical work has accordingly shifted its focus towards multi-product firms and their product mix decisions....

In this paper we provide a broad overview of the computable general equilibrium (CGE) literature on the Uruguay Round, detailing the policy experiments of various studies and differences in model structures and relating these to the overall pattern of results. We supplement this overview with a...
