This paper seeks to integrate more closely the theory of optimum currency areas with the theory of international trade. The currency area is considered as a continuous variable ranging from zero to one: zero if there is no enlargement, and some positive value otherwise, corresponding exactly to...

We draw attention to the role of economic geography in explaining important cross-sectional facts which are difficult to account for in existing models of industrialization. By construction, closed-economy models that stress the role of local demand in generating sufficient expenditure on...

This paper reviews the recent theoretical literature on heterogeneous firms and trade, which emphasizes firm selection into international markets and reallocations of resources across firms. We discuss the empirical challenges that motivated this research and its relationship to traditional...

What is the impact of movement towards free trade on output? Can this impact permanently affect output levels, and more importantly, will it have an impact on steady-state growth rates? This paper provides empirical evidence showing how countries have exhibited substantial increases in their...

Despite current economic problems and conflicts - or perhaps as their cause - the concordance of policies among the major industrial countries in the first half of the 1980s in dealing with finance, trade and development is at a peak. This has been the result not so much of cooperation or...

This new model of international trade patterns is based on differing relative labor costs derived from differing endowments of skilled and unskilled labor, when labor is in elastic supply because of social support systems. All factors other than labor are assumed to be mobile across frontiers;...

We formulate a two-country model with monopolistic competition and heterogeneous firms to reconsider labor market linkages in open economies. Labor-market imperfections arise by virtue of country-specific real minimum wages. Two principal experiments are considered. First, we show that trade...

This paper considers the locational choice of firms in an upstream and a downstream industry. Both industries are imperfectly competitive, with firms subject to increasing returns. There are transport costs between the two locations. Depending on the level of these costs there may be a single...

A series of models are developed in which international trade is modelled as a two-stage game between firms in two countries. At the first stage firms choose their productive capacity. At the second stage different types of market game are played. The most interesting case is that in which firms...
