Migration and Employment Change: Empirical Evidence on the Spatial and Temporal Dimensions of the Linkage*

"This paper uses a unique set of U.S. data to estimate the magnitude of the linkages between employment changes and net employment migration. A simple simultaneous system is specified and estimated for 17 consecutive years. In an average year two extra jobs attract about one additional net migrant, and one additional net migrant has a direct effect on area employment of almost 1.4 jobs." The data are from the One-Percent Social Security Continuous Work History Sample and are for the years 1958 to 1975. The changes in this relationship over time as the economic situation varies are analyzed.
