title: A dynamic model of regional population growth and decline.
abstract: "This paper presents a two-sector dynamic model of regional population change.  The model contains a migration equation, an earnings equation, and an amenity equation for each region.  In the context of this model, migration is seen as a disequilibrium process through which the regional populations move towards equilibrium positions.  Migration occurs when one region is perceived to be superior to the other on the basis of its earnings and amenity levels.  Equilibrium is achieved when population movements between the regions eliminate any differences in their relative attractiveness.  A comparative-static analysis of the model is presented to analyze the effects of policy changes and exogenous shocks on the distribution of population among the regions."  The geographical focus is on the United States.
