We estimate the causal effect of having full health insurance on health care expenditures. We take advantage of a unique quasi-experimental setup in which deductibles and co-payments were zero in a managed care plan, and non-zero in regular insurance, until a policy change forced all individuals...

Recent theoretical research has identified many ways how contracts can be used as rent seeking devices vis-à-vis third parties, but there is no empirical evidence on this issue so far. To test some basic qualitative properties of this literature, we develop a theoretical and empirical framework...

How large are the economies of scale of living together? And how do partners share their resources? The first question is usually answered by equivalence scales. Traditional estimation and application of equivalence scales assumes equal sharing of income within the household. This paper uses...

In many countries, caseworkers in a public employment office have the dual roles ofcounselling and monitoring unemployed persons. These roles often conflict with each otherleading to important caseworker heterogeneity: Some consider providing services to theirclients and satisfying their demands...

This paper extends the traditional focus of active labor market policy evaluation from a staticcomparison of participation in a program versus nonparticipation (or participation in anotherprogram) to the evaluation of the effects of program sequences, i.e. multiple participation ortiming of such...

We evaluate a randomized experiment of a statistical support system developed to assistcaseworkers in Swiss employment offices in choosing appropriate active labour marketprogrammes for their unemployed clients. This statistical support system predicted the labourmarket outcome for each...

This paper examines whether contacts between caseworkers in public employment officesand employers impact on the reemployment chances of the unemployed they counsel. Thisanalysis is made possible through a large administrative dataset on unemployed combinedwith an extensive survey of...

In an evaluation of a job-training program, the influence of the program on the individualearnings capacity is important, because it reflects the program effect on human capital.Estimating these effects is complicated because earnings are observed for employedindividuals only, and employment is...

We provide new evidence on the effectiveness of West German labour market programmesby evaluating training and employment programmes that have been conducted 2000-2002after the first large reform of German labour market policy in 1998. We employ exceptionallyrich administrative data that allow...

This paper assesses the performance of common estimators adjusting for differences in covariates, such as matching and regression, when faced with so-called common support problems. It also shows how different procedures suggested in the literature affect the properties of such estimators. Based...
