Competition between opposing lobbies is an important factor in the endogenous determination of trade policy. This paper investigates empirically the consequences of lobbying competition between upstream and downstream producers for trade policy. The theoretical structure underlying the empirical...

Existing estimates of power laws in firm size typically ignore the impact of international trade. Using a simple theoretical framework, we show that international trade systematically affects the distribution of firm size: the power law exponent among exporting firms should be strictly lower in...

This paper evaluates the global welfare impact of observed levels of migration using a quantitative multi-sector model of the world economy calibrated to aggregate and firm-level data. Our framework features cross-country labor productivity difference, international trade, remittances, and a...

This paper provides a forensic account of the role of individual firms in generating aggregate fluctuations using data covering the universe of French firms for the period 1990–2007. We derive a theoretically-founded set of estimating equations that decompose firms’ annual sales growth rate...

This paper evaluates the global welfare impact of China's trade integration and technological change in a multi-country quantitative Ricardian-Heckscher-Ohlin model. We simulate two alternative growth scenarios: a "balanced" one in which China's productivity grows at the same rate in each...
