Cartel ringleaders can apply for amnesty in some jurisdictions (e.g., the E.U.), whereas in othersthey are excluded (e.g., the U.S.). This paper provides a survey of identified ringleaders inrecent European cartel cases and explores theoretically the effect of ringleader exclusion oncollusive...

We provide an explanation for the common finding that the effect of retirement on life satisfaction is negligible. For this we use subjective well-being measures for life and domains of life satisfaction that are available in the German Socio-Economic Panel (GSOEP) and show that the effect of...

In this paper we experimentally investigate whether partial coercion can in combination withconditional cooperation increase contributions to a public good. We are especially interested inthe behavior of the non-coerced populations. The main finding is that in our setting conditionalcooperation...

Economic and social interaction takes place between individuals with heterogeneous characteristics. We investigate experimentally the emergence and informal enforcement of different contribution norms to a public good in homogeneous and different heterogeneous groups. When punishment is not...

This paper greatly enriches the discussion on the determinants of lifelong learning of scientists and engineers (S&Es). In our analysis, which is based on a survey among S&Es in the Netherlands, we take account of both formal training and different modes of informal learning. We find that S&Es...

We present constant approximative policies for preemptive stochastic scheduling. We derive policies with a guaranteed performance ratio of 2 for scheduling jobs with release dates on identical parallel machines subject to minimizing the sum of weighted completion times. Our policies as well as...

Evidence about job mobility outside the U.S. is scarce and difficult to compare cross-nationally because of non-uniform data. We document job mobility patterns of college graduates in their first three years in the labor market, using unique uniform data covering 11 European countries and Japan....

This paper assesses the impact of a dramatic reform of the Dutch pension system on mental health, savings behavior and retirement expectations of workers nearing retirement age. The reform means that public sector workers born on January 1, 1950 or later face a substantial reduction in their...

We argue that rules and rule-following provide a key means of solving social dilemmas by revealinginformation about individual willingness to cooperate, thereby facilitating assortative matchingand the exclusion of non-cooperative types. Rules impose costs on prospective entrants to anygroup and...

In this paper we formalize the notion of lexicographic belief hierarchies in standard partitional models (Aumann, 1976). We introduce the notion of epistemic equivalence between two belief space, and show that the state space representation of lexicographic belief hierarchies is equivalent to...
