Equilibrium and disequilibrium perspectives on regional labor migration.

Some alternative models of labor migration in the United States are reviewed, with particular reference to the distinction between equilibrium and disequilibrium models of migration. The authors propose alternative tests to a model developed by Joseph Schacter and Paul G. Althaus "which explicitly recognize the stock-flow interactions between net migration and the distribution of regional population stocks and which make a clean distinction between equilibrium in the temporal and in the market-clearing sense."
