The minimum covariance determinant (MCD) estimators of multivariate location and scatter are robust alternatives to the ordinary sample mean and sample covariance matrix. Nowadays they are used to determine robust Mahalanobis distances in a reweighting procedure, and used as robust plug-ins in all...

This paper studies the efficiency of educational choices in a search-matching model where individuals face a tradeoff between acquiring formal education and learning-by-doing while on-the-job. The labor market is hierarchically segmented into two sectors. When their educational effort is successful...

Because of sorting, more skilled workers are more productive in higher type firms. They also learn at different rates about their productivity and therefore have different wage paths across firms. We show that under supermodularity there is always Positive Assortative Matching: differential...

We study a market with free entry and exit of firms that can costly invest in their quality. If the investment is observable, the first best is characterized by high quality and a large output. If the investment is non observable, free entry creates adverse selection, blocking market existence. If...

This study provides a first set of experimental results highlighting a new mechanism for racial discrimination, based on a cognitive limitation in facial re-identification across races. An experiment is conducted to study how people record and recall payoff-relevant information about others, within...

This paper introduces endogenous and directed technical change in a growth model with environmental constraints and limited resources. A unique final good is produced by combining inputs from two sectors. One of these sectors uses "dirty" machines and thus creates environmental degradation....

This paper uses a unique data set and the exogenous nature of the conflict and resulting displacement in Northern Uganda to examine their impacts on labour market participation. I find that the longer the existence of the Internally Displaced People's camp to which individuals moved, the less men...

This paper provides evidence on the relevance of the mode collection for the analysis of consumption data for the United States using complementary data sets from the Consumer Expenditure Surveys (CEX). We first show that population figures from consumption reports obtained with diaries markedly...

This paper characterizes the optimal income taxation when individuals respond along both the intensive and extensive margins. Individuals are heterogeneous in two dimensions: their skills and their disutility of participation. Preferences over consumption and work effort can differ with the skill...
