MIGRATION AND EMPLOYMENT CHANGE: EMPIRICAL EVIDENCE ON THE SPATIAL AND TEMPORAL DIMENSIONS OF THE LINKAGE*
利用美国1958-1975年数据，估计就业变化与净迁移之间的双向影响：每增加两个就业岗位约吸引一个净移民，而每个净移民直接带来约1.4个就业岗位。
"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.
