Lottery estimates suggest oversubscribed urban charter schools boost student achievement markedly. But these estimates needn’t capture treatment effects for students who haven’t applied to charter schools or for students attending charters for which demand is weak. This paper reports...

Policy-makers have argued that providing public health insurance coverage to the uninsured lowers long-run costs by reducing the need for expensive hospitalizations and emergency department visits later in life. In this paper, we provide evidence for such a phenomenon by exploiting a legislated...

This paper uses the rollout of the first Community Health Centers (CHCs) to study the longer-term health effects of increasing access to primary care. Within ten years, CHCs are associated with a reduction in age-adjusted mortality rates of 2 percent among those 50 and older. The implied 7 to 13...

We use data from Sierra Leone where a substantial education program provided increased access to education for primary-school age children but did not benefit children who were older. We exploit the variation in access to the program generated by date of birth and the variation in resources...

We examine heterogeneity in the impacts of exposure to mixed-ability ‘comprehensive’ schools in adolescence on long-term health and smoking behaviour. We explore the roles that cognitive and non-cognitive skills may play in moderating these impacts. We use data from the 1958 National Child...

We report results from our long-standing research partnership with the Massachusetts Department of Elementary and Secondary Education. We make two primary contributions. First, we illustrate the wide range of informative analyses that can be conducted using a state longitudinal data system and...

Does financial aid increase college attendance and completion? Selection bias and the high implicit tax rates imposed by overlapping aid programs make this question difficult to answer. This paper reports initial findings from a randomized evaluation of a large privately-funded scholarship...

We estimate causal effects of tax refunds (cash-on-hand) on college enrollment using population-level administrative data from United States income tax returns. We implement two separate research designs based on tax refunds from the Earned Income Tax Credit (EITC). First, we exploit a...

We examine the channels through which a randomized early childhood intervention in Colombia led to significant gains in cognitive and socio-emotional skills among a sample of disadvantaged children. We estimate production functions for cognitive and socio-emotional skills as a function of...

We model the labor market impact of the three key provisions of the recent Massachusetts and national "mandate-based" health reforms: individual and employer mandates and expansions in publicly-subsidized coverage. Using our model, we characterize the compensating differential for...
