Migration equilibrium with price rigidity: the Harris and Todaro model revisited

The author attempts to build a general equilibrium model with migration possibilities on the lines of the Harris-Todaro model in which all the agents have explicit maximizing behavior. "Assumptions on wage-price rigidities allow consideration of various supply-demand configurations. One of the most interesting results is that policy recommendations derived from the usual Harris-Todaro model are not valid when excess supply prevails." The focus is on the situation in developing countries.
