近日，我院蔡郑宇副教授与美国爱荷华州立大学John Winters副教授、俄克拉荷马州立大学Karen Maguire副教授以及Shruti Sengupta博士合作，于国际知名区域经济学期刊《区域科学学刊》（Journal of Regional Science）在线发表论文《Causal effects of the fracking boom on long-term resident workers》。页岩气兴起对劳动力市场表现的影响在文献中已经存在较多研究，但在实证工作中工人内生的迁移行为往往被忽视。该论文使用了一个创新的工具变量来应对内生的迁移行为，是对现有实证证据的重要补充。

论文摘要：

Horizontal drilling innovations revolutionized the U.S. oil and gas industry and facilitated a boom in production in the mid‐2000s in regions with shale and tight‐sands reservoirs. This paper examines the effects of the boom on individual employment and earnings within boom states. We account for endogenous migration decisions by using a novel instrument for oil and gas production in workers' state of residence. We find statistically significant and economically meaningful positive effects of the oil and gas boom for long‐term resident workers, those who were born in and reside in their home state.
