This paper provides a method to study heterogenous social interactions in a large network. The method is based on a maximum score model with social interactions where the social interactions are modeled in a simultaneous discrete game. The heterogenous social interactions parameters 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...

We adopt a framework to specify a household's child development technology with a set of interdependent inputs and outputs, finding significant, productive dynamic effects due to young children's Head Start participation. Our panel data estimates show that initial counter-productive partial...

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....

This paper addresses the question of whether the effect of parental drinking on children’s later consumption of alcohol - which is frequently found to be of positive sign - exhibits a certain pattern of heterogeneity. In particular, if this effect is more prominent in the upper tail than...

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...

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...

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...

El objetivo principal de esta investigación es el de realizar un estudio de la eficiencia en los hospitales del Sistema Nacional de Salud por Comunidad Autónoma (CCAA). El estudio se realiza sobre los hospitales gestionados por cada Servicio de Salud Autonómico con más de 500 camas sobre la...
