This paper develops a simple framework for examining human capital accumulation, unemployment, and relative wages in a global economy. It builds on the models of Davis (1998a, b) of trade between a flexible-wage America and a rigid-wage Europe. To this it adds a model of human capital accumulation based on Findlay and Kierzkowski (1983). A variety of comparative statics are examined, including changes in educational capital and population, entry of new countries to the trading world, technical change, and a productivity slowdown. We derive the consequences for the skilled-to unskilled wage gap, unemployment, and skill composition.
