This paper complements existing power analysis tools by offering tools to compute minimum detectable effect sizes (MDES) for existing studies and to estimate minimum required sample sizes (MRSS) for studies under design. The tools that accompany this paper support estimates of MDES or MSSR for 21 different study designs that include 14 random assignment designs (6 designs in which individuals are randomly assigned to treatment or control condition and 8 in which clusters of individuals are randomly assigned to condition, with models differing depending on whether the sample was blocked prior to random assignment and by whether the analytic models …

Child care subsidies help low-income families pay for child care while parents work or study. Few studies have examined the effects of child care subsidy use on child development, and no studies have done so controlling for prior cognitive skills. We use rich, longitudinal data from the ECLS-B data set to estimate the relationship between child care subsidy use and school readiness, using value-added regression models as well as parametric and non-parametric models with propensity score matching. Compared to a diverse group of subsidy non-recipients in various types of non-parental care as well as parental care only, we find that …

The persistent achievement gaps among children of different race/ethnicity and socioeconomic status in the United States represent an issue that has commanded public, policy, and research attention on and off for about 100 years now, and it is once again in the forefront of policy-making agendas. Debates nevertheless abound on the most promising and cost-effective strategies to address the problem. We examine critically the available evidence on the benefits and costs of early childhood education and conclude that early, vigorous interventions targeted at disadvantaged children offer the best chance to substantially reduce gaps in school readiness and increase the productivity …
