To what extent can Czech exporters cushion the impact of currency appreciation shocks by using imported intermediates? We apply a partial equilibrium model with firms that are heterogeneous in their productivities. Producers can serve the domestic market, export final goods, or import inputs. In...

Recent quantitative trade models treat import tariffs as pure cost shifters so that their effects are similar to iceberg trade costs. We introduce revenue-generating import tariffs, which act as demand shifters, into the framework of Arkolakis, Costinot and Rodriguez-Clare (2012), and generalize...

This paper presents a tractable formalization and an empirical investigation of the quality-complementarity hypothesis, the hypothesis that input quality and plant productivity are complementary in generating output quality. We embed this complementarity in a general-equilibrium trade model with...

We introduce search and matching unemployment into a model of trade with differentiated goods and heterogeneous firms. Countries may differ with respect to size, geographical location, and labor market institutions. Contrary to the literature, our single-sector perspective pays special attention...

Fixed entry costs play an important role to explain the heterogeneity among exporters in terms of the geographical scope of their export activities. Yet, the existing literature has paid little attention to the nature and variation of such costs across different markets. This paper proposes a...

This paper reviews the recent theoretical literature on heterogeneous firms and trade, whichemphasizes firm selection into international markets and reallocations of resources acrossfirms. We discuss the empirical challenges that motivated this research and its relationship totraditional trade...

This paper develops a model of trade and CO2 emissions with heterogenous firms, where firms make abatement investments and thereby have an impact on their level of emissions. The model shows that investments in abatements are positively related to firm productivity and firm exports. Emission...

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...
