Marijuana legalization and disability claiming
研究美国娱乐用大麻合法化对社会保障残疾保险和补充保障收入申请及批准的影响，发现合法化增加了申请量但未改变批准率，原因可能与大麻滥用、选择性迁移和失业率下降有关。
We study the effect of recent legalization of recreational marijuana use laws (RMLs) in the United States on new applications and allowances for Social Security Disability Insurance and Supplemental Security Income over the period 2001-2019. We combine administrative caseload data from the Social Security Administration with state policy changes using two-way fixed-effects methods. We find that RML adoption increases applications for both benefits. However, there is no change in allowances post-RML. We provide suggestive evidence that the observed changes in applications post-RML are driven by increases in marijuana misuse and selective migration, and decreases in unemployment.
