Although the practice of military conscription was widespread during most of the past century, credible evidence on the effects of mandatory service is limited. Angrist (1990) showed that the Vietnam-era draft in the U.S. lowered the early-career wages of conscripts, a finding he attributed to...

There is widespread belief that workers in temporary agency work (TAW) are subject topoorer working conditions, in particular pay, than comparable workers in the rest of theeconomy. The first aim of this analysis is to quantify the wage penalty, if any, for workers inTAW. Secondly, we analyze...

This paper shows nonparametric identification of quantile treatment effects (QTE) in the regression discontinuity design. The distributional impacts of social programs such as welfare, education, training programs and unemployment insurance are of large interest to economists. QTE are an...

This paper proposes a nonparametric method for evaluating treatment effects in the presence of both treatment endogeneity and attrition/non-response bias, using two instrumental variables. Making use of a discrete instrument for the treatment and a continuous instrument for...

This paper develops a nonparametric methodology for treatment evaluation with multiple outcome periods under treatment endogeneity and missing outcomes. We use instrumental variables, pre-treatment characteristics, and short-term (or intermediate) outcomes to identify the average treatment...

This paper evaluates the effects of a major Swedish school choice reform. The reform in 1992 increased school choice and competition among public schools as well as through a large-scale introduction of private schools. We estimate the effects of school choice and competition, using precise...

We estimate the effects of active labour market policies (ALMP) on subsequent employment by nonparametric instrumental variables and matching estimators. Very informative administrative Swiss data with detailed regional information are combined with exogenous regional variation in programme...

This paper investigates the finite sample performance of a comprehensive set of semi- and nonparametric estimators for treatment and policy evaluation. In contrast to previous simulation studies which mostly considered semiparametric approaches relying on parametric propensity score estimation,...

We analyze a mechanism that has been disregarded in the literature on parental investment in children, as little attention has been devoted to the choices made by children themselves. We model directly time use by youngsters into activities related to the acquisition of human capital,...
