Looking around the world, we observe substantial differences across countries in prices for most goods. These price differences also tend to be positively correlated with income differences, so that citizens of high-income countries tend to pay more for the same goods than citizens in low-income...

The authors study a variation of the Melitz (2003) model, a monopolistically competitive model with heterogeneity in productivity across establishments and fixed costs of exporting. They calibrate the model to match the employment size distribution of US manufacturing establishments. Export...

Using firm level data, Bernard and Jensen (1995, 1999, 2001) find that exporters are bigger and more productive than non-exporters. These studies also find that the identity of exporting firms changes over time and that fixed entry and participation costs influence firm's decision to enter and...

This paper evaluates the welfare gains to trade reform in a model of endogenous export participation. Specifically, assuming that firms face an up-front, sunk cost of entering foreign markets and a smaller period-by-period continuation cost, we derive the discrete entry and exit decisions...

In a closed economy general equilibrium model, Hopenhayn and Rogerson (1993) find large welfare gains to removing firing restrictions. We explore the extent to which international trade alters this result. When economies trade, labor market policies in one country spill over to other countries...

We study the relation between international trade and the gains to reform labor markets by removing firing restrictions. We find that trade linkages imply substantially smaller benefits to reform than those calculated in the closed economy general equilibrium model of Hopenhayn and Rogerson...

We study the source and consequences of sluggish export dynamics in emerging markets following large devaluations. We document two main features of exports that are puzzling for standard trade models. First, given the change in relative prices, exports tend to grow gradually following a...
