A Note on the Benefits to Current Residents of State Employment Growth: Is There an Industry Mix Effect on Migration?
利用1981-1991年美国48个州的数据，研究发现州就业增长中来自全国快速增长行业的份额越大，净迁入人口越少，而各行业自身增长快于全国平均时则相反，说明产业组合影响迁移并影响现有居民福利。
Although there is evidence that regional employment growth benefits current residents, an unexplored aspect of this relationship is the industry composition of the growth. Using 1981–1991 migration data for the 48 contiguous U.S. states, this paper examines whether the industry mix of employment growth matters for migration. We find that state employment growth that results from having a larger share of nationally fast‐growing industries leads to less net in‐migration compared to growth that results from each industry in the state growing faster than its national average. Therefore, state employment growth that is attributable to its mix of industries yields greater benefits for current state residents.
