RESPONSE TO REGULATORY STRINGENCY: THE CASE OF ANTIPSYCHOTIC MEDICATION USE IN NURSING HOMES
研究了2000-2005年间美国养老院监管严格程度（以过去一年全州缺陷引用率衡量）对抗精神病药物使用比例的影响，发现监管效果取决于缺陷与药物使用的互补性，存在多任务激励问题。
This paper studies the impact of regulatory stringency, as measured by the statewide deficiency citation rate over the past year, on the quality of care provided in a national sample of nursing homes from 2000 to 2005. The quality measure used is the proportion of residents who are using antipsychotic medication. Although the changing case-mix of nursing home residents accounts for some of the increase in the use of antipsychotics, we find that the use of antipsychotics by nursing homes is responsive to state regulatory enforcement in a manner consistent with the multitasking incentive problem. Specifically, the effect of the regulations is dependent on the degree of complementarity between the regulatory deficiency and the use of antipsychotics.
