We develop a general equilibrium model of trade between identical countries. The model is similar to a 2x2x2 Heckser-Ohlin model, but the factors of production, skilled and unskilled labor, are endogenously determined from human capital investments by the workers. Firms are only able to observe...

We consider a general equilibrium model with endogenous human capital formation in which ex ante identical groups may be treated differently in equilibrium due to informational externalities. Unlike earlier models of statistical discrimination, group inequalities may arise even if the...

We consider a model of endogenous human capital formation with competitively determined wages, where discrimination between ex ante identical groups is sustainable in equilibrium. An affirmative action policy consisting of a quota may "fail" in the sense that there still may be equilibria where...
