Recent theoretical work predicts that an important margin of adjustment to deregulation or trade reforms is the reallocation of output within firms through changes in their product mix. Empirical work has accordingly shifted its focus towards multi-product firms and their product mix decisions....

This paper traces the links from trade shocks to poverty in developing countries. It considers the determinants of household and individual welfare (including potential differences between household members) and then identifies six trade-to-poverty links: the extent to which prices change and...

This paper examines international trade policy within a completed European internal market. The Ethier-Horn argument for internal tariffs in a customs union is shown to be inapplicable to most of the EC's existing, cost-increasing barriers to trade. The implications are examined of abolishing...

We examine the consequences of increased economic integration between nations within a region. We adopt Krugman’s economic-geography model in which demand linkages can generate agglomeration of manufacturing activity. Manufacturing labour is assumed to be imperfectly mobile between countries....

This paper argues that the application of the `2% rule' to the case of Eastern Germany, which implies convergence in three decades or more, is overly pessimistic. First, it ignores discrete improvements in initial conditions related to the transition, which have been significant to date. Because...

We consider a Heckscher-Ohlin model in which goods and factors of production can be traded, but trade involves transactions costs. Goods trade alone will not equalize factor prices, so there is an incentive for trade in factors of production. Whether goods or factors are traded depends on...

We return to a familiar topic in international trade, comparative advantage, introducing it into a model of economic geography. We provide a clear counterexample to the familiar result that trade liberalization leads to increased industrial concentration. Instead, lower trade costs may lead to a...

In models of economic geography, plant-level scale economies and trade costs create incentives for spatial agglomeration of production into a manufacturing core and agricultural periphery, creating regional income differentials. We examine tax competition between national governments to...
