Boom Town Business Dynamics
利用美国页岩油气繁荣作为自然实验，研究经济增长如何通过新企业创建而非现有企业扩张来带动多行业就业增长，对理解劳动力市场扩张和商业调整机制有参考价值。
The U.S. shale oil and gas boom provides a unique opportunity to study economic growth in a "boom town" environment, derive insights about labor market expansions more generally, and identify the causal effects of economic growth on specific margins of business adjustment. Creation of new establishments—separate from expansion of existing establishments—accounts for a disproportionate share of the multi-industry employment growth sparked by the shale boom, an intuitive but not inevitable empirical result that is consistent with models of firm dynamics. New firms, in particular, contribute nearly half of the cumulative employment growth resulting from the shale boom.
