Health effects of cash transfers: Evidence from the Finnish basic income experiment
研究芬兰基本收入实验发现，无条件现金转移支付通过增加收入减少了失业者精神药物使用8%-11%，但对其他健康指标无显著影响。
This study provides causal evidence that cash transfer programs have the potential to alleviate the income–health trap in advanced countries. We analyze the Finnish basic income experiment, which replaced the minimum unemployment benefits with a guaranteed income for 2,000 randomly selected unemployed persons during the years 2017–2018. The guaranteed income removed all job–search requirements, but participants could still choose to claim unemployment benefits and comply with related obligations. The experiment also increased average income by 9 %–11 %, for two reasons: basic income payments overlapped with benefits due from the pre-experiment period, and basic income was not tapered against labor earnings. Using register data on all prescription medications and secondary care visits, we find that the experiment reduced psychotropic drug use by 8 %–11 %. Our results also suggest a decline in outpatient mental health visits for secondary care. No effects were detected for other health outcomes. Since most participants opted out of the unconditionality aspect of the experiment and continued to claim unemployment benefits, we attribute the observed health effects primarily to the increased income.
