This paper examines the response of industries and firms to changes in trade costs. Several new firm-level models of international trade with heterogeneous firms predict that industry productivity will rise as trade costs fall due to the reallocation of activity across plants within an industry. Using disaggregated U.S. import data, we create a new measure of trade costs over time and industrie...

This paper models and analyzes international trade flows using open flow networks (OFNs) with the approaches of flow distances, which provide a novel perspective and effective tools for the study of international trade. We discuss the establishment of OFNs of international trade from two coupled viewpoints: the viewpoint of trading commodity flow and that of money flow. Based on the novel model...

trade relationships built through production chains appear to be lasting due to relation-specific nature of the transactions, compared with the usual transactions of goods sold on the open market. this paper aims to verify such stability of international production networks at the global level, with special emphasis on intra-east asian trade. a series of survival analyses provide an evidence su...

The first objective of the field of international trade is to understand why countries trade. Such a positive account of the origins of trade must precede policy analysis. The 1980s were dominated by a single major advance in thinking about trade patterns. It is sufficiently important that Krugman [1990] is justified in calling it a “quiet revolution”. Imperfect competition in product markets a...

Although initially originated as a totally empirical relationship to explain the volume of trade between two partners, gravity equation has been the focus of several theoretic models that try to explain it. Specialization models are of great importance in providing a solid theoretic ground for gravity equation in bilateral trade. Some research papers try to improve specialization models by addi...

I investigate the determinants of business cycles synchronization, across regions and over time. I use both international and intranational data to evaluate the linkages between trade in goods, trade in ...nancial assets, specialization and business cycles synchronization in the context of a system of simultaneous equations. In all speci...cations, the results are as follows. (i) Simultaneity i...
