I develop a stylized model of multi-stage production in which the time length of each stage is endogenously determined. Letting the production process mature for a longer period of time increases labor productivity, but it comes at the cost of higher working capital needs for firms. Under...

What are the gains from international trade? And how do immigrants influence this process? We consider the case of Canada, document its experience with import variety growth in the period from 1988 to 2007, and relate this variety growth to the process of immigration. We find that import...

Recent empirical research in international trade has revealed overwhelming evidence that, in all countries, a remarkably small proportion of firms report exports in Customs statistics. However, a large share of these are wholesalers. This suggests that the number of producers selling their...

This chapter focuses on the estimation and interpretation of gravity equations for bilateral trade. This necessarily involves a careful consideration of the theoretical underpinnings since it has become clear that naive approaches to estimation lead to biased and frequently misinterpreted...

This paper presents a tractable formalization and an empirical investigation of the quality-complementarity hypothesis, the hypothesis that input quality and plant productivity are complementary in generating output quality. We embed this complementarity in a general-equilibrium trade model with...

Recent research in international trade emphasizes the importance of firms' extensive margins for understanding overall patterns of trade as well as how firms respond to specific events such as trade liberalization. In this paper, we use detailed U.S. trade statistics to provide a broad overview...

This paper estimates a heterogeneous firms trade model using sector level data on export participation, trade flows, and unit value prices in a multi-country setting. Examining within-exporter variation in prices across destinations, prices are increasing in the difficulty of entering the...

We use Belgian data on domestic firm-to-firm transactions and ask how the measurement of the share of imports in final consumption is affected when one uses data recorded at higher levels of aggregation. We find that aggregating detailed firm-to-firm transaction data to the firm level and...

This paper studies the implications of household heterogeneity for trade. I develop a model where household heterogeneity is induced via incomplete markets and results in heterogeneous price elasticities. Conditional on exposure to trade, heterogeneous price elasticities imply that different...

We investigate the role of evidence-based information in shaping individuals' preferences for trade policies through a series of survey experiments that contain randomized information treatments. Each treatment provides a concise statement of economics research findings on how openness to trade...
