This paper derives a new effect of trade liberalisation on the quality of the environment. We show that in the presence of heterogeneous firms the aggregate volume of emissions is influenced not only by the long-established scale effect, but also by a reallocation effect resulting from an...

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...

This paper assesses whether the sensitivity of bilateral trade volumes to various trade cost factors is constant or varies across countries. It utilizes a random coeffcients model and analyses a cross-sectional sample of bilateral trade data for 96 countries in 2005. We expect the elasticity of...

Historically, tariffs have been an attractive policy tool to protect domestic industries. The benefits of such a policy are based on theoretical models that assume foreign manufacturers sell directly to consumers. However, recent empirical evidence suggests that wholesalers and retailers play an...

We propose a stylized monopolistic competition model of international trade where firms differ with respect to the expected economic lifetime of their innovations. Upon entry, they receive a commonly observed signal which is updated over time. Jointly with partial irreversibility of investment,...

We address the trade effect of restrictive product standards on the margins of trade, by matching a detailed panel of French firm exports with a new database compiling the list of Sanitary and Phyto-Sanitary regulatory measures that have been raised as a concern in dedicated committees of the...

Increasing wage inequality between similar workers plays an important role for overall inequality trends in industrialized societies. To analyze this pattern, we incorporate directed labor market search into a dynamic model of international trade with heterogeneous firms and homogeneous workers....

What insights can be gained from bringing the theory of the firm to the global economy? I discuss several new features of the world economy that can be explained by incorporating the theory of the firm into the theory of international trade. Among the new features I discuss are the move to...

Firms adjust to differences in market size and demand uncertainty by changing the frequency and size of their export shipments. In our inventory model, transportation costs and optimal shipment frequency are determined on the basis of demand as well as inventory and per shipments costs. Using a...

We study a multinational enterprise’s (MNE) choice of foreign direct investment (FDI) mode in a vertically related market with local input sourcing. We show that the vertical structure of the market and its features play a crucial role for the MNE.s decision: backward linkages, enhanced...
