In this paper we investigate the effects of delinquency and arrest on school leaving using information on males from the National Longitudinal Survey of Youth 1997. We use a multivariate mixed proportional hazard framework in order to account for common unobserved confounders and reverse...

Two econometric issues arise in the estimation of complete systems of producer or consumer demands when many non-negativity constraints are binding for a large share of observations, as frequently occurs with micro-level data. The first is computational. The econometric model is essentially an...

There is hardly any study on learning inequalities during the COVID-19 pandemic in a low-income, multi-country context. Analyzing 34 longitudinal household and phone survey rounds from Burkina Faso, Ethiopia, Malawi, Mali, Nigeria, Tanzania, and Uganda, we find that while countries exhibit...

We show why considering a number of education-dependent covariates in the wage equation decreases coefficient of education in the wage equation. We use a meta-analysis of results for Portugal to show, empirically, that this is the case. The coefficient decreases when we use covariates that can...

This paper presents a method of calculating sharp bounds on the average treatment effect using linear programming under identifying assumptions commonly used in the literature. This new method provides a sensitivity analysis of the identifying assumptions and missing data in an application...

For the 65 colleges and universities that participate in the Power Five athletic conferences (Pac 12, Big 10, SEC, ACC, and Big 12), the football and men's basketball teams are highly visible. While these programs generate tens of millions of dollars in revenue annually, very few of them turn an...

A non-trivial portion of traffic fatalities involve alcohol or illicit drugs. But does the use of alcohol and illegal substances—which is linked to depression, suicide, and crime—reduce academic performance? Recent studies suggest that drinking has a negative, if modest, effect on grades,...

A non-trivial portion of traffic fatalities involve alcohol or illicit drugs. But does substance use—which is linked to depression, suicide, and criminal activity—also reduce academic performance? Recent studies suggest that the consumption of alcohol has a negative effect on the grades of...
