Migrant information, job search and the remigration decision.

"Labor force migration poses two important questions for the economist. The first concerns the nature, magnitude and direction of labor force response to perceived earnings differentials over space. The latter and more complex question concerns the effectiveness, or efficiency, of this response--namely migration--and other market mechanisms in reducing these earnings differentials over time." Both questions are addressed in this paper "by examining relationships among: (1) quality of information obtained prior to a move, (2) search duration at the migration destination, and (3) the likelihood of subsequent (perhaps corrective) remigration." These relationships are analyzed using the human capital model of migration-remigration and data from the 1970 U.S. census.
