In this paper we provide an integrative treatment of the welfare effects of trade and industrial policy under oligopoly, and characterize qualitatively the form that optimal intervention takes under a variety of assumptions about the number of firms, their conjectures about the response of their...

Does national market size matter for industrial structure? This has been suggested by theoretical work on home market' effects, as in Krugman (1980, 1995). In this paper, I show that what previously was regarded as an assumption of convenience - transport costs only for the differentiated goods...

This paper considers why non-monetary means of exchange, such as barter and the reciprocation of favors, are chosen by firms despite the usual benefits of monetary transactions. We consider the chosen means of exchange when both monetary and non-monetary exchange mechanisms are available. We...

Measures of long term trends in world export prices of manufactured goods and in the terms of trade between manufactured goods and primary products are sensitive to the choice of country weights and of base periods and, most important of all, the treatment of quality change. Later base periods...

Almost all of the large literature on international trade with imperfect competition assumes exogenous market structures. The purpose of this paper is to develop a simple model that generates alternative market structures as Nash equilibria for different parameterizations of the basic model....

We study how international trade affects manufacturing employment and the relative wage of unskilled workers when goods and services are traded with different intensities. Manufacturing trade reduces manufacturing prices worldwide, which reduces manufacturing employment if manufactures and...

Short run gravity is a geometric weighted average of long run gravity and bilateral capacity. The model features (i) joint trade costs endogenous to bilateral volumes, (ii) long run gravity as a limiting case of efficient investment in bilateral capacities, (iii) a structural ratio of short run...

We investigate the role of industry specialization in horizontal cross-border mergers and acquisitions. We find that acquirers from more specialized industries in a country are more likely to buy foreign targets in countries that are less specialized in these same industries. The role of...
