Most international commerce is carried out by multinational firms, which use their foreign affiliates both to serve the market of the host country and to export to other markets outside the host country. In this paper, I examine the determinants of multinational firms' location and production...

This paper studies the effects of marketing choice to firm growth. I assume that firm-level growth is the result of idiosyncratic productivity improvements with continuous arrival of new potential producers. A firm enters a market if it is profitable to incur the marginal cost to reach the first...

This paper surveys the theoretical and empirical literature on the relationship between the spatial distribution of economic activity and transportation costs. We develop a multi-region model of economic geography that we use to understand the general equilibrium implications of transportation...

In an economy with imperfect labor contracts, differences in the distribution of human capital are an independent source of comparative advantage. I study a world economy with two sectors, one where output is produced by teams and another where individuals can work alone. When workers' abilities...

We study a simple, tractable model of labor adjustment in a trade model that allows us to analyze the economy's dynamic response to trade liberalization. Since it is a neoclassical market-clearing model, we can use duality techniques to study the equilibrium, and despite its simplicity a rich...

This paper develops and estimates an overlapping generations general equilibrium model of labor earnings, skill formation and physical capital accumulation with heterogeneous human capital. The model analyzes both schooling choices and post-school on-the-job investment in skills in a framework...

This paper formulates and estimates an open-economy overlapping generation general-equilibrium model of endogenous heterogeneous human capital in the form of schooling and on-the-job training. Physical capital accumulation is also analyzed. We use the model to explain rising wage inequality in...

This paper presents a computable general equilibrium model that simulates the effects on employment, output, wages, and economic efficiency of introducing comparable worth into the U.S. economy. The model calculates economy-wide aggregate impacts and disaggregated results for individuals grouped...

This paper presents ex post decomposition analysis of wage inequality change using multi-sector general equilibrium models. The analytical structure used is a specific- factors model of trade, which we calibrate to UK data for the two years 1979 and 1975. We first calibrate our general...
