On the importance of public choice in migration models.

ECONOMICS LETTERS. 1998 Jun; 59(3):373-9.

Recent general equilibrium Tiebout models that use single-crossing indifference curves to establish a migration equilibrium incorporate both voting and migration decisions. These models have concentrated on the important question of the existence of an equilibrium, but the incorporation of both voting and migration has important efficiency consequences as well. This paper demonstrates the important effect of the interaction of voting and migration on efficiency conditions by showing that head taxes (which are generally considered to provide efficient migration incentives with constant marginal congestion costs) do not provide incentives for efficient migration decisions unless the public choice mechanism results in optimal public service provision within jurisdictions.
