Development accounting exercises based on an aggregate production function find technology is biased in favour of a country's abundant production factors. We provide an explanation to this finding based on the Heckscher-Ohlin model. Countries trade and specialize in the industries that use...

We construct and numerically solve a dynamic Heckscher-Ohlin model in which the initial distribution of production factors in the world makes worldwide factor price equalization impossible, and leads countries to group in two diversification cones. We study the dynamics of income per capita and...

We present a dynamic comparative advantage model in which moderate reductions in import tariffs can generate sizable increases in trade volumes over time. A fall in import tariffs has two effects on the volume of trade. First, for given factor endowments, it raises the degree of specialization...
