We study the effect of exposure to older, more experienced classroom peers resulting from the widespread use of multi-grade classes in Scottish primary schools. For identification, we exploit that a class-planning algorithm quasi-randomly assigns groups of pupils to multi-grade classes. We find...

In this article we study the effects of permanent school closures on crime. We leverage the closure of over 300 schools in Scotland between the school years 2006/07 and 2018/19, and employ a staggered difference-in-differences design on a matched sample. We find that neighbourhoods affected by...

This study examines the effects of U.S. state-level marijuana policies on mental health. Using data from three nationally representative data sets and estimating difference-in-differences models that account for the staggered implementation of both medical and recreational marijuana legislation,...

In this paper, we study how classmate gender composition matters for students in Ethiopia. We base our results on a unique survey of students across classrooms and schools and among those randomly assigned to class. We find a strong asymmetry: males do not and females do benefit from exposure to...

The alcohol industry argues that alcohol excise taxes do not reduce heavy drinking because of substitutions to lower-cost products and that these taxes disproportionately burden low-income drinkers. Alternatively, some economists have argued that increases in alcohol excise taxes reduce heavy...

This paper examines the effects of education on health and hospitalization over the life cycle. Using administrative data, we leverage a 1972 compulsory schooling reform within the United Kingdom which produced a large increase in educational attainment among affected cohorts. Our regression...

This paper applies semiparametric regression models to shed light on the relationship between body weight and labor market outcomes in Germany. We find conclusive evidence that these relationships are poorly described by linear or quadratic OLS specifications, which have been the main approaches...

We show that tax-induced increases in alcohol prices can lead to substantial substitution and avoidance behavior that limits reductions in alcohol consumption. Causal estimates are derived from a natural experiment in Illinois where spirits and wine taxes were raised sharply and unexpectedly in...

This study evaluates the effects of the 2018 UK Soft Drinks Industry Levy on soft drinks prices, sales, reformulation activities, and consequently calories consumed. We combine novel electronic point of sale data that cover most of the UK soft drinks market with longitudinal nutritional...
