JUE Insight: What is the impact of opportunity zones on job postings?
利用美国在线职位发布的近乎全量数据，通过倾向得分匹配和双重差分模型，研究发现机会区计划对职位发布平均影响有限，但在城市、黑人人口中位数以上地区及部分州有微小正面效应。
We study the effect of Opportunity Zones (OZs) on job postings using data comprising the near-universe of U.S. online job postings. The OZs program grants tax breaks for investment in designated distressed communities, nominated by each state’s governor based on multiple factors. We use propensity score matching to account for those factors and a difference-in-differences model over the matched sample to estimate the effect of the program. We find limited evidence of any effect of OZs on job postings on average, although we do find small positive effects in urban areas, in areas with above median Black population, and in some states.
