There has been much attention for the causes of the increase in wageinequality in the United States since the mid seventies. DiNardo,Fortin, and Lemieux (1996) showed that minimum wages can explain 25%. The present paper uses a more general approach requiring noassumptions on how minimum wages...

I apply Ricardo’s principle of comparative advantage to a theory of factor substitutability in a model with a continuum of worker and job types. Highly skilled workers have a comparative advantage in complex jobs. The model satisfies the distance-dependent elasticity of substitution (DIDES)...

The paper applies Ricardo's principle of comparative advantage to analyze the substitutability between types of labor. The problem of having to classify labor in a small number of types in e.g. standard CES models are avoided by applying a continuum of worker and job types, where better skilled...
