In this paper, we provide evidence that compensatory education policies that target schools in socially deprived areas are likely to create a negative signal resulting in a sorting effect. We investigate this effect by analyzing the French "Réseaux ambition réussite" (RAR) program, which...

In this paper we consider the problem of adaptive density or survival function estimation in an additive model de ned by Z = X + Y with X independent of Y , when both random variables are nonnegative. We want to recover the distribution of X (density or survival function) through n observations...

We investigate the estimation of the ?-fold convolution of the density of an unob- served variable X from n i.i.d. observations of the convolution model Y = X + ?. We first assume that the density of the noise ? is known and define nonadaptive estimators, for which we provide bounds for the mean...

What shapes the size of a personal network of family and friends? We concentrates here on the effect of retirement from the work force. Retirement provides time to develop personal relationships; but it deprives from a potential supply of colleague friends. We draw evidence from a new question...

In this paper we consider the problem of adaptive estimation of random-e ects densities in linear mixed-e ects model. The linear mixed-e ects model is de ned as Yk;j = k + ktj + "k;j where Yk;j is the observed value for individual k at time tj for k = 1; : : : ;N and j = 1; : : : ; J. Random...

Being retired goes with more frequent participation in some social activities such as volunteering or going to a club. It also goes with an increase in the intensity of participation. To conclude about a causal effect of retirement we use the longitudinal SHARE data and an IV strategy. Indeed we...

While most of the literature on employment protection has focused on government-mandated severance pay, it has recently been documented that a substantial share of severance payments derives from private contracts or collective agreements. This paper studies the determination of these payments....

This study evaluates the impact of an increase in childcare subsidies on the use of paid childcare and the participation rate of mothers of preschool children. We use a natural experiment provided by the PAJE, a French reform in family allowances introduced in 2004. This reform temporarily...

The assumption that consumers are fully rational and hold correct expectations over prices is demanding in dynamic settings. We claim that it is testable provided that market-level data on prices and purchases are available. We find that consumers hold simple expectations on the timing of...

The basic assumption of a structural VARMA model (SVARMA) is that it is driven by a white noise whose components are uncorrelated (or independent) and are interpreted as economic shocks, called "structural" shocks. These models have to face two kinds of identification problems. The first...
