This paper designs a multiarmed bandit sequential model for the analysis of the migration-job search process. Th e implications either are compatible with well-known migration behavi or or, when novel, are also plausible. For example, regions with larg e wage variability attract migrants, and regions with large nonpecuni ary returns increase both in migration and out migration. A major adv antage of this approach is the relative ease with which martingale es timators can be derived from the martingale structure of the model. T hese martingale methods are exemplified for the return migration phen omenon. Copyright 1987 by University of Chicago Press.
