"In this paper, we analyze the transition dynamics associated with an economy's response to trade liberalization. We start by reviewing the recent literature that incorporates firm dynamics into models of international trade. We then build upon that literature to characterize the role of firm dynamics, export-market selection, firm-level innovation, and firms' expectations regarding the time path of liberalization in generating those transition dynamics following trade liberalization. These modeling ingredients generate substantial aggregate transition dynamics as they shift and shape the endogenous distribution of firms over time. Our results show how the responses of trade volumes, innovation, and aggregate output can vary greatly over time depending on those modeling ingredients. This has important consequences for many issues in international economics that rely on predictions for the effects of globalization over time on those key aggregate outcomes"--National Bureau of Economic Research web site

"How do trade liberalizations affect relative factor prices and to what extent do they cause factors to reallocate across sectors? We first present a general framework that nests a wide range of models that have been used to study the link between globalization and factor prices. Under some restrictions, changes in the "factor content of trade" are sufficient statistics for the impact of trade on relative factor prices. We then study the determination of the factor content of trade in a specific version of our general framework featuring imperfect competition, increasing returns to scale, and heterogeneous producers. We show how heterogeneous firms' decisions shape the factor content of trade, and, therefore, the impact of trade liberalization on relative factor prices and between-sector factor allocation"--National Bureau of Economic Research web site

"We construct a model of international trade and multinational production (MP) to examine the impact of globalization on the skill premium in skill-abundant and skill-scarce countries. The key mechanisms in our framework arise from the interaction between three elements: cross-country differences in factor endowments and sectoral productivities, technological heterogeneity across producers within sectors, and skill-biased technology. Reductions in trade and/or MP costs induce a reallocation of resources towards a country's comparative advantage sector (increasing the skill premium in skill-abundant countries and reducing it in skill-scarce countries) and within sectors towards more productive and skill-intensive producers (increasing the skill premium in all countries).We parameterize the model to match salient features of the extent and composition of trade and MP between the U.S. and skill-abundant and skill-scarce countries in 2006. We show that a reduction in trade and MP costs, moving from autarky to 2006 levels of trade and MP, increases the skill premium by roughly 5% in skill-abundant and skill-scarce countries. We also show that the growth in US trade and MP between 1966 and 2006 accounts for 1/9th of the 24% rise in the US skill premium over this period. MP is at least as important as international trade in generating this rise in the skill premium"--National Bureau of Economic Research web site

"Countries that are more engaged in production sharing exhibit higher bilateral manufacturing output correlations. We use data on trade flows between US multinationals and their affiliates as well as trade between the United States and Mexican maquiladoras to measure production-sharing trade and its link with the business cycle. We then develop a quantitative model of international business cycles that generates a positive link between the extent of vertically integrated production-sharing trade and internationally synchronized business cycles. A key assumption in the model is a relatively low elasticity of substitution between home and foreign inputs in the production of the vertically integrated good"--National Bureau of Economic Research web site

Managerial know-how shapes the productivity of firms by defining the set of available technologies, production choices, and market opportunities. This know-how can be reallocated across countries as managers acquire control of factors of production abroad. In this paper, we construct a quantitative model of cross-country income differences to study the aggregate consequences of international mobility of managerial know-how. We use the model and aggregate data to infer the relative scarcity of this form of know-how for a sample of developing countries. We also conduct policy counterfactuals and find that on average, developing countries gain up to 23% in output and 9% in consumption when they eliminate all barriers to foreign control of domestic factors of production.
