Endogenous Stratification in Randomized Experiments

Abstract: Policymakers are often interested in estimating how policy interventions affect the outcomes of those most in need of help. This concern has motivated the practice of disaggregating experimental results by groups constructed on the basis of an index of baseline characteristics that predicts the values of individual outcomes without the treatment. This paper shows that substantial biases may arise in practice if the index is estimated by regressing the outcome variable on baseline characteristics for the full sample of experimental controls. We propose alternative methods that correct this bias and show that they behave well in realistic scenarios.

Children's Mental Health Care: Differences by Race/Ethnicity in Urban/Rural Areas

Abstract: This study examines racial/ethnic disparities in children's mental health and the receipt of mental health services, and whether those disparities differ between urban and rural areas. We find no significant difference between racial/ethnic groups in the prevalence of child mental health problems in either urban or rural areas. However, there are disparities in the use of mental health services. Hispanic children and Black children in urban areas receive less mental health care than their White counterparts, and the disparity persists for Hispanic children in rural areas, even after controlling for other relevant factors. Initiatives to improve access to mental health care for racial/ethnic minorities should recognize these disparities, and address the lack of culturally appropriate services in both urban and rural areas. In addition, outreach should raise awareness among parents, teachers, and other community members concerning the need for mental health services for minority children.

The Impact of the Medicaid/CHIP Expansions on Children: A Synthesis of the Evidence

Abstract: This article reviews findings from 38 rigorous studies published in the peer-reviewed literature of the impact of the Medicaid/Children's Health Insurance Program (CHIP) expansions on children. There is strong evidence for increases in enrollment in public programs and reductions in uninsurance following eligibility expansions. Medicaid enrollment continued to increase during the CHIP era (a "spillover effect"). Evidence for improved access to and use of services, particularly for dental care, is also very strong. There are fewer studies of health status impacts, and the evidence is mixed. There is a very wide range in the size of effects estimated in the studies reviewed because of the methods used and the populations studied. The review identifies several important research gaps on this topic, particularly the small number of studies of the effects on health status. Both research methods and findings from the child expansions can provide insights for evaluating the coming expansions for adults under the Affordable Care Act.

Effects of tort reforms and other factors on medical malpractice insurance premiums.

Abstract: We use state-level data on physician malpractice premiums, claims, and awards, provided by insurance companies for the years 1974 to 1986, to evaluate the effectiveness of the various tort reforms that have been legislated during the 1970s and 1980s. In addition to the tort reforms, our analysis of premiums considers insurers' anticipated losses, returns on investments, the type of insurer, and premium regulation. Our results suggest that the only reforms that significantly lower premiums are those that either impose a cap on the amount of physician liability or reduce the amount of time a plaintiff has to initiate a claim. We also find that premiums are lower when states regulate rates by requiring prior approval of premiums. In addition, it appears that the observed cyclicality in premiums is due, in part, to fluctuations in the real interest rates available to insurers as returns on investments. Unfortunately, we did not find as strong a link between the determinants of premiums, claims, and awards as might be expected.
