Employment Under Marijuana
研究美国娱乐大麻合法化如何影响企业就业，发现其显著降低就业，尤其在高技能劳动力和工会力量强的企业中，并进一步减少投资、销售增长和创新。
Abstract This study examines the impact of recreational marijuana laws (RMLs) on firm-level employment using an imputation-based difference-in-differences (DiD) approach across U.S. states. RMLs significantly reduce employment, particularly among firms with high-skilled labor, strong union presence, permissive corporate cultures, and in states with greater dispensary density. Alternative explanations—including economic crises, COVID-19, fiscal changes, labor regulations, and related policies such as smoking bans and right-to-work (RTW) laws—are systematically ruled out through a series of placebo and robustness tests. RMLs also reduce investment, sales growth, and innovation, suggesting that legalization introduces labor-related frictions with broad implications for firm performance and long-term dynamism.
