Abstract：This study examines how regulations in private health insurance markets affect coverage of public insurance. We focus on mental health parity laws, which mandate private health insurance to provide equal coverage for mental and physical health services. The implementation of mental health parity laws may improve a quality dimension of private health insurance but at increased costs. We graphically develop a conceptual framework and then empirically examine whether the regulations shift individuals from private to public insurance. We exploit state-by-year variation in policy implementation in 1999–2008 and focus on a sample of veterans, who have better access to public insurance than non-veterans. Using data from the Current Population Survey, we find that the parity laws reduce employer-sponsored insurance (ESI) coverage by 2.1% points. The drop in ESI is largely offset by enrollment gains in public insurance, namely through the Veterans Affairs (VA) benefit and Medicaid/Medicare programs.

该论文研究了美国私人医疗保险市场管理制度对公共医疗保险覆盖率的溢出效用。在众多保险管理制度中，作者侧重分析了精神健康保险强制平等法案，该法案规定私人医疗保险计划必须为精神健康的检查和治疗提供与生理健康同等水平的医疗服务保障。该法案的实施将会在提高私人医疗保险质量的同时增加购买保险的成本。根据这一特性，论文建立了相应的理论模型并实证检验了该管理法案是否将医疗保险消费者从私人保险转移到公共保险。利用1999年到2008年不同州政府对该强制法案的实施情况以及退伍军人（有更多的公共医疗保险资源）这样一种特殊人群，研究发现精神健康强制性平等法案降低了2.1个百分点的雇主提供医疗保险覆盖率，同时增加了公共保险（退伍军人医疗险和Medicaid/Medicare）覆盖率。
