In markets where sellers are able to price discriminate, or the buyers to bargain, individuals receive discounts over the posted prices that are usually not observed by the econometrician. This paper considers the structural estimation of a demand and supply model à la Berry et al. (1995) when...

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...

Once individual unobserved heterogeneity and human capital depreci- ation have proved not to fully account for wage di erences consecutive to parenthood, a remaining explanation (discrimination aside) could be that parents select into low wage rms. This paper tests that hypothesis by resorting...

L’hypergamie féminine, définie comme la propension des individus à former des couples au sein desquels la femme se trouve en infériorité par rapport à l’homme, est un phénomène observé dans de nombreuses sociétés et du point de vue de nombreux critères. À l’encontre d’une...

En 1962, l’accession de l’Algérie à l’indépendance a entrainé le départ massif vers la métropole des Français qui y étaient installés. Or, bien que leur arrivée remonte désormais à plus de cinquante ans, on ne dispose toujours pas d’études approfondies sur le parcours de ces...
