Migration and Credit Constraints: Theory and Evidence from Vietnam

The new economics of labor migration (NELM) frequently emphasizes the importance of migration as a way for rural households to overcome credit constraints. If this hypothesis is correct, then the credit constraint is a motivation for migration (a relaxation of this constraint would encourage less migration). Conventionally, it is believed that migration is costly and has to be financed with borrowed capital, so the credit constraint is a deterrent of migration (a relaxation of this constraint would encourage more migration). In this paper, an agricultural household model is developed to study whether the credit constraint is a motivation for or a deterrent to migration. The model's result confirms the NELM's hypothesis: for households with high demand for agricultural investments and high net migration return, migration is used as a way to finance capital investments. Using data from four provinces in Vietnam, preliminary evidence is found supporting this hypothesis.
