Reducing drink drive limits is generally regarded an effective strategy to save lives on the road. Using several new administrative data sources, we evaluate the effect of a stricter limit introduced in Scotland in 2014. This reduction had no effect on drink driving and road collisions....

This note takes a first look at the distribution of returns to education for people with disabilities, a particularly disadvantaged group whose labor market performances have not been well studied or documented. Using a nonparametric approach, we uncover significant heterogeneity in the returns...

Throughout the years spanned by the U.S. Vital Statistics Linked Birth and Infant Death Data (1983-2002), birth weights are measured most precisely for children of white and highly educated mothers. As a result, less healthy children, who are more likely to be of low socioeconomic status, are...

We examine a new general class of hazard rate models for survival data, containing a parametric and a nonparametric component. Both can be a mix of a time effect and (possibly time-dependent) marker or covariate effects. A number of well-known models are special cases. In a counting process...

When the running variable in a regression discontinuity (RD) design is measured with error, identification of the local average treatment effect of interest will typically fail. While the form of this measurement error varies across applications, in many cases the measurement error structure is...

Although the theoretical trade-off between the quantity and quality of children is well-established, empirical evidence supporting such a causal relationship - particularly on child health - is limited. We use two measures of child health to asses the quantity-quality trade-off across the entire...

Food security and obesity represent two of the most significant public health issues. However, little is known about how these issues are intertwined. Here, we assess the causal relationship between food security during early childhood and relatively long-run measures of child health....

We document considerable within-person (over time) variation in diet quality that is not fully explained by responses to fluctuations in the economic environment. We propose a two-selves model that provides a structural interpretation to this variation, in which food choices are a compromise...

Although lower income is associated with overweight (and obesity), such an association is explained by a number of other confounding effects such as omitted variables (e.g., time preferences) explaining that income effect on overweight. We study the effect of unearned income shocks resulting...

Twenty-six states require that women seeking an abortion wait between 18 and 72 hours after receipt of counseling before the abortion can be completed. Thirteen states require that the counseling be given in person necessitating at least two visits to the provider. In April of 2015, Arkansas...
