If public funds are allocated efficiently, then an increase in funding should improve the performance of substance abuse treatment programs. In the data used in this paper, performance (measured as abstinence rates) and expenditures per patient are not positively correlated. One explanation is that funding is endogeneous, i.e. programs treating more difficult patients receive more funding. The data comes from all Maine's outpatient drug-free programs that received public funding between 1991 and 1994. After controlling for endogeneity, this paper concludes that the marginal impact of expenditures per patient on abstinence rates is small and statistically insignificantly different from zero.
如果公共资金得到有效分配，那么资金增加应该会改善药物滥用治疗项目的绩效。在本文所使用的数据中，绩效（以戒酒率衡量）与每位患者的支出并非正相关。一种解释是资金是内生的，即治疗更困难患者的项目会获得更多资金。数据来自1991年至1994年间缅因州所有获得公共资金的门诊戒毒项目。在控制了内生性之后，本文得出结论，每位患者的支出对戒酒率的边际影响很小，且在统计上与零没有显著差异。
