The authors study the effects of tariffs in a dynamic variation of the Melitz (2003) model, a monopolistically competitive model with heterogeneity in productivity across establishments and fixed costs of exporting. With fixed costs of starting to export that are on average 3.7 times as large as...

We build a micro-founded two-country dynamic general equilibrium model in which trade responds more to a cut in tariffs in the long run than in the short run. The model introduces a time element to the fixed-variable cost trade-off in a heterogeneous producer trade model. Thus, the dynamics of...

We study how the transitions following a trade reform are shaped by the time it takes for new exporters to grow in the export market. We introduce time and risk into the fixed-variable cost tradeoff central to general equilibrium heterogeneous firm trade models: Investing in exporting gradually...

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...
