Firms play a critical role in the global economy. In this paper, we survey the behavior of firms in the international economy, both in theory and in the data. We first summarize the key empirical facts that motivate the study of firms in trade. Then, we detail recent theoretical developments on...

We present a North-South model of international trade in which differentiated products are developed in the North. Sectors are populated by final-good producers who differ in productivity levels. Based on productivity and sectoral characteristics, firms decide whether to integrate into the...

Gravity variables such as distance, adjacency, colony, free trade agreements or language are used to capture the effects of trade costs in empirical studies. By using actual data on trade costs, this paper decomposes the overall effects of such variables on trade into those through three gravity...

This paper introduces quality innovations with endogenous sunk costs in a heterogeneous firm model of international trade and derives implications for the gravity equation. The model predicts that the effect of fixed costs on exports and on the share of exporters is lower in industries with a...

Preferential trade agreements are meant to promote trade within the targeted region. Once such agreements are put into effect, it is interesting to investigate the impact and effectiveness in the targeted region. This paper analyzes world trade network as a graph and introduces the measure to...

This paper provides an economic analysis of the trade conflict between the US and China, providing an overview of the tariff increases, a discussion of the background of the trade conflict, and an analysis of the economic effects of the trade conflict, based both on empirics (ex post analysis)...

This paper analyzes the European integration of the Turkish industry in view of a comparative trade analysis of the Turkish economy and the EU economies. We perform a thorough depiction of the various aspects of the trade integration of Turkey, most notably in the fields of the trade patterns,...

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...

There is no escaping Japan's competition in the world markets for goods, particularly in the automotive and electronics industries. Countries exporting to these markets are bound to feel the competitive pressure from a marked fall in the value of the yen. However, while some exporters will be...

While some exporters to the world markets for goods may be hurt by a cheaper yen, others will benefit from lower input costs, to the extent that they source parts and components from Japan for processing, assembly and reexport. This paper formalizes these intuitions and tests them against data...
