In observational studies, the non-parametric estimation of a binary treatment effect is often performed by matching each treated individual with a control unit which is similar in observed characteristics (covariates). In practical applications, the reservoir of covariates available may be...

We extend the standard evaluation framework to allow for interactions between individuals within segmented markets. An individual's outcome depends not only on the assigned treatment status but also on (features of) the distribution of treatments in his market. To evaluate how the distribution...

By comparing mean outcomes for a large number of matched samples of participants and nonparticipants we estimate individual earnings effect of the Norwegian labour market training programme (LMT) targeted at unemployed adults in the years 1991-1996. The average training effect on the trained is...

Individual long run effects of a labour market training programme targeted at unemployed adults are evaluated by comparing mean post-training earnings for matched samples of participants and non-participants. Average training effects on the trained are positive and persistent over the...

This paper evaluates the effect of an anti-poverty program, Chile Solidario, during its first two years of operation. We find that the program tends to increases significantly their take-up of cash assistance programs and of social programs for housing and employment, and to improve education...

Nonparametric estimators of treatment effects are often applied in settings where clustering may be important. We provide a general methodology for consistently estimating the variance of a large class of nonparametric estimators, including the simple matching estimator, in the presence of...

In this paper we examine the impact of subsidies granted at national and regional levels on a set of R&D employment variables and, specifically, we seek to identify the existence of the behavioural additionality effects of these public subsidies on firms’ R&D human resources. We begin by...

A new matching method is proposed for the estimation of the average treatment effect of social policy interventions (e.g., training programs or health care measures. Given an outcome variable, a treatment and a set of pre-treatment covariates, the method is based on the examination of random...

Utilizando información censal de las sedes educativas rurales de Colombia el presente trabajo evalúa el impacto que tuvo el Programa de Educación Rural -PER - en las tasas de eficiencia (cobertura, reprobación, aprobación y deserción) y calidad de la educación en las sedes en donde se...
