Actual and potential competition is a powerful source of discipline on the pricing behavior of firms with market power. A simple model is developed that shows that the effects of import competition and domestic entry regulation on industry price-cost markups depend on country size. Barriers to...

This paper develops a model of international trade where firms are heterogeneous across capacity and productivity. A binding capacity constraint induces firms to raise prices in order to take advantage of access to new markets. This generates markets with a flexible competitive structure giving...

Large multi-product firms dominate international trade flows. This paper documents new facts about multi-product manufacturing exporters that are not easily reconciled with existing multi-product models. Using novel linked production and export data at the firm-product level, we find that the...

Over the last decades Argentina’s living standards have lost ground relative to other developed and emerging economies. Putting Argentina on a path to stronger, inclusive and job-rich growth requires boosting productivity and strengthening investment through wide-ranging structural reforms....

The dynamics of export market exit and firm closure have found limited attention in the new heterogeneous-firms trade literature. In fact, several of the predictions on firm survival and exit stemming from this new class of models are at odds with the stylized facts. Empirically, higher...

This paper derives optimal trade and domestic taxes for a small open economy containing a monopolistically competitive (MC) sector in which firms may have heterogeneous productivity levels. Domestic protection brings gains from expanding the number of product varieties on offer, but these gains...

The paper sets up a two-country asymmetric trade model with heterogeneous firms, search frictions and endogenous labor market institutions. Countries are linked by trade in goods and non-cooperatively set unemployment benefits to maximize national welfare. We show that more open and smaller...

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...

Can tax policy foster the creation of new companies? To answer this question, we assemble a novel country-industry level panel database with data on entry (by incorporation) for 17 European countries between 1997 and 2004. Our analysis is based on recent models of how corporate taxation affects...
