Developing countries made considerable gains during the first decade of the 21st century. Their economies grew at unprecedented rates, resulting in large reductions in extreme poverty and a significant expansion of the middle class. But more recently that progress has slowed with an economic...

This paper examines the role of agricultural diversity in the process of development. Using data from U.S. counties and exploiting climate-induced variation in agricultural production patterns, I show that mid-19th century agricultural diversity had positive long-run effects on population...

This paper uses the natural experiment of Argentina's integration into world markets in the late-nineteenth century to provide evidence on the role of internal geography in shaping the effects of external integration. We develop a quantitative model of the distribution of economic activity...

This paper develops a model in which the rivalry of oligopolistic firms serves as an independent cause of international trade. The model shows how such rivalry naturally gives rise to "dumping" of output in foreign markets, and shows that such dumping can be "reciprocal" -- that is, there may be...

The Cobden-Chevalier treaty of 1860 eliminated many French import prohibitions and lowered tariffs between France and Britain. Policy change was largely unexpected and unusually free from direct lobbying. A series of commercial treaties with other nations followed because of the use of the...

Our paper integrates results from trade-in-task theory into mainstream trade theory by developing trade-in-task analogues to the four famous theorems (Heckscher-Ohlin, factor price equalisation, Stolper-Samuelson, and Rybczynski) and showing the standard gains-from-trade theorem does not hold...

This paper presents and tests a new model of multinational firms to explain a rich array of multinational behavior. In contrast to most approaches, here the multinational faces costs to transferring its know-how that are increasing in technological complexity. Costly technology transfer gives...

This paper shows that the results of Venables (1987) depend critically on the assumption that there are no fixed costs of trade. The introduction of fixed costs of exporting, while making the model more consistent with the empirical evidence, leads to the opposite conclusion that technological...
