Typically, the error term in stochastic frontier models is assumed to be positively skewed; however, efficiency scores are biased if this assumption is violated. This paper considers the case in which also negative skewness is allowed in the model. In contrast to other approaches, this skewness is...

This paper considers the role of school closures in the spread of the SARS-CoV-2 virus. To isolate the impact of the closures from other containment measures and identify a causal effect, we exploit variation in the start and end dates of the summer school and fall holiday across the 16 federal...

Using administrative data on incomes and healthcare spending, we develop new evidence on the distribution of healthcare spending in Hungary. We document substantial geographic heterogeneity and a positive association between income and public healthcare spending.
