We provide experimental evidence of workers' ingratiation by opinion conformity and of managers' discrimination in favor of workers with whom they share similar opinions. In our Baseline, managers can observe both workers' performance at a task and opinions before assigning unequal payoffs. In...

We verify whether an income support policy for part-time workers in Belgium increases the transition from unemployment to non-subsidised, "regular" employment. Using a sample of 8630 long-term unemployed young women, whose labour market history is observed from 1998 to 2001, we implement the...

We present a compound Poisson model describing the occurrence process of a set of words in a random sequence of letters. The model takes into account the frequency of the words and their overlapping structure. The model is compared with a Markov chain model in terms of fit and parsimony. Special...

We analyze the micro rationale of EU-sponsored collaborations compared to non-sponsored, spontaneous collaborations. We compare the incentives and coordination mechanisms of each type of collaboration, and derive propositions that we test empirically. Our econometric analysis uses recent data on...

In this paper, the problem of variable selection in classification is considered. On the basis of recent developments in model selection theory, we provide a criterion based on penalized empirical risk, where the penalization explicitly takes into account the number of variables of the...

Competition among producers within an integrated electricity system is impeded by any limited transmission capacity there may be at its borders. Two alternative market mechanisms have recently been designed to organize the allocation of scarce transmission capacity at cross-border level : (i)...
