In this paper we investigate how firms adjust markups across products in response to fluctuations in the real exchange rate. In a theoretical framework, we show that firms increase their markup and producer prices following a real depreciation and that this increase is greater for products with...

This paper uses firm-level data for Mexican exporters to understand how firm-level export decisions shape a country's aggregate exports. The data allows for a characterization of both the crosssectional distribution of Mexican exports, across destinations and across exporting firms, and of the...

After establishing that exporters obtain higher margins than non-exporters, the paper takes a new look at export premia by comparing multi-product exporters' costs, prices and markups on the domestic and foreign markets. This firm-product-market analysis is made possible thanks to a unique...

In this paper we propose a novel method for the price-cost markup estimation and study the relationship between export intensity and the markup. We impose much less restrictive identifying assumptions on technology and adjustment frictions compared to previous studies and use Swedish firm-level...

This paper studies the relationship between firm-level markups and trade status using balance sheet information linked to detailed trade data from Hungary between 1995-2003. We find that importing is strongly positively correlated with markups both across and within firms. We argue that this...

Building on a heterogeneous-firm model à la Melitz (2003), we propose a theory of intermediaries in international trade which rationalizes the available evidence on both aggregate and firm-level exports as well as their responsiveness to exchange rate movements. We introduce double...

With non-homothetic preferences, a monopolistic competition equilibrium is inefficient. In a setting with heterogeneous firms that charge variable markups, this paper finds a sufficient statistic for changes in allocative efficiency that can be directly measured with data. The model also...

Products produced by a multiproduct firm can be linked through demand linkages or supply linkages. On the demand side, changes in the price of one product can affect the demand for a firm's other products through shifts in consumer expenditures. This is commonly referred to as the...
