This paper considers the semiparametric identification of endogenous and exogenous peer effects based on group size variation. We show that Lee (2006)’s linear-in-means model is generically identified, even when all members of the group are not observed. While unnecessary in general,...

This paper considers the semiparametric identification of endogenousand exogenous peer effects in the linear-in-means model. We showthat this model is generically identified when at least three differentsizes of peer groups are observed in the sample at hand. While unnecessaryin general,...

This paper studies the econometric properties of a linear-in-means model of social interactions. Under a slightly more restrictive framework than Lee (2007), we show that this model is generally identified when at least three different sizes of peer groups are observed in the sample at hand....

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...

The text aims to present the basic principles of what the author calls the «residential» economy. He recalls that the theoretical basis of this proposal lies in already old concept «theory of the base.» The author describes four types of local economy: productive, public, residential and...

We evaluate the impact of reimbursement rates on health expenditures, using a natural experiment. For historical reasons, reimbursement rates of public health insurance are higher in the French region Alsace Moselle than in other French regions. For both systems, affiliation is compulsory....

This paper evaluates the French RAR program (Réseaux Ambition Réussite or Ambition Success Networks), a junior high school program started in 2006 which intended to concentrate means and funds on well-chosen disadvantaged junior high schools. We use the criteria of eligibility to estimate a...
