We investigate theoretically and empirically the competitive effects of increased trade on prices, productivity and markups. Using disaggregated data for EU manufacturing over the period 1988-2000 we find increased openness exerts a negative and significant impact on sectoral prices. Increased...

Import competition from China is pervasive in the sense that for many good categories, the competitive environment that US firms face in these markets is strongly driven by the prices of Chinese imports, and so is their pricing decision. This paper quantifies the effect of the...

In this Paper we present an overview of a number of issues relating to the equilibrium exchange rates of the new EU member states from Central and Eastern Europe. In particular, we present a critical overview of the various methods available for calculating equilibrium exchange rates and discuss...

This paper provides evidence that learning about demand is an important driver of firms' dynamics. We present a simple model with Bayesian learning in which firms are uncertain about their idiosyncratic demand parameter in each of the markets they serve, and update their beliefs as noisy...

We show that the labor market effects of product line relocations within multi-product firms differ significantly from the relocation of production tasks within single-product firms. By incorporating offshoring of labor-intensive goods in a model with multi-product firms, and exploring its...

A firm's productivity depends on how production is organized given the level of demand for its product. To capture this mechanism, we develop a theory of an economy where firms with heterogeneous demands use labor and knowledge to produce. Entrepreneurs decide the number of layers of management...

I survey the influence of Grossman and Hart's (1986) seminal paper in the field of International Trade. I discuss the implementation of the theory in open-economy environments and its implications for the international organization of production and the structure of international trade flows. I...

This paper presents novel empirical evidence on key predictions of heterogeneous firm models by examining stock market reactions to the Canada-United States Free Trade Agreement of 1989 (CUSFTA). Using the uncertainty surrounding the agreement's ratification, I show that the pattern of abnormal...

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...
