We use 6-digit bilateral trade data to document the effect of WTO/GATT membership on the extensive and intensive product margins of trade. We construct gravity equations for the two product margins motivated by Chaney (2008). The empirical results show that standard gravity variables provide...

I find evidence that the geographic expansion of firm exports occurs slowly over time and that a large share of export growth is due to incumbent exporters entering new destinations. New exporters enter large countries and destinations with characteristics similar to their domestic market. Less...

This paper explores the impact of input trade liberalization on imported input and exported product prices. Using Chinese transaction data for 2000–2006, we capture causal effects between exogenous input tariff reductions and within firm changes in HS6-traded product prices. For...

In this paper, we analyze the effect of reducing import tariffs on intermediate inputs and final goods on the wage skill premium within firms in Indonesia – a country with a high share of unskilled workers. We present a new finding that reducing input tariffs reduces the wage skill premium...

I construct a model with endogenous growth and new economic geography. Using this framework, I consider the outcomes of R&D subsidy competition among countries under different trade costs. When trade costs are higher, less industrialized countries are more eager to attract industries with...

This paper derives a micro-founded gravity equation based on a translog demand system that allows for flexible substitution patterns across goods. In contrast to the standard CES-based gravity equation, translog gravity generates an endogenous trade cost elasticity. Trade is more sensitive to...

We derive a micro-founded measure of bilateral trade integration that is consistent with a broad range of leading gravity models. This measure accounts for cross-industry heterogeneity by incorporating substitution elasticities estimated at the industry level. We then use it to provide a...

Exporting firms do not only decide how much of their products they ship abroad but also at which frequency. Doing so, they face a trade-off between saving on fixed costs per shipments (by shipping large amounts infrequently) and saving on storage costs (by delivering just in time with small and...

Distance effects in gravity equations are high and are not decreasing over time. Given that technical change in transport technology is biased in favor of long distances, this constitutes a challenge for existing theoretical models. In line with recent empirical evidence, this paper introduces a...

This paper studies how a country's labor market institutions, by affecting workers' skill acquisition, can shape its export patterns. I develop an open-economy model in which workers undertake non-contractible activities to acquire firm-specific skills on the job. In the model, labor market...
