Moving to Economic Opportunity
利用页岩气开采带来的正向劳动力市场冲击，研究发现开采区吸引了更多移民，但移民群体以年轻、未婚、低学历男性为主，且不同地区间迁移率差异显著。
ABSTRACT Exploiting positive labor market shocks from localized "fracking" booms, I estimate that fracking increased migration to impacted areas, but there is significant heterogeneity across both demographics and regions. Migrants to fracking areas were more likely to be male, unmarried, young, and less educated than movers more generally. These local booms increased in-migration rates to North Dakota fracking counties by nearly twice as much as other fracking areas. Differences across geography in labor market impacts, commuting behavior, initial population characteristics, or nonlinearities only partially explained this gap. There is evidence that heterogeneous information flows might be playing a role.
