Seasonal agricultural activity and crime
利用1990-2016年美国县级月度数据，研究发现劳动密集型季节性农业活动（如果蔬园艺业）降低了财产和暴力犯罪率，可能通过改善本地劳动力市场机会减少犯罪动机。
Abstract Sudden shocks to labor demand have sometimes been shown to increase local crime rates. We build on this literature by estimating the causal effect of labor‐intensive seasonal agricultural activity on crime. We analyze a unique data set that describes criminal activity and fruit, vegetable, and horticultural (FVH) employment by month and U.S. county from 1990 to 2016. We find that the FVH labor share is associated with reduced property and violent crime rates, and possibly the number of property crimes committed within county years. Examining heterogeneities based on ethnicity, labor‐intensive FVH activity decreases the rate of non‐Hispanic arrests and victimization, and increases the number of Hispanic arrests and victims (consistent with rising local Hispanic populations). Taken together, results are broadly consistent with the idea that agricultural harvest of labor‐intensive crops enhances local labor market opportunities that reduce incentives to commit crimes. Results are robust to a battery of alternative specifications that address the inherent challenges associated with measuring seasonal agricultural labor.
