A recurrent problem in economic studies based on survey data is to determine whether survey weights should be used or not. We show that weighted estimators are more robust than unweighted ones, but less accurate when unweighted estimators are consistent. In some circumstances, a compatibility...

In this article, we focus on the estimation of outpatient expenditures with panel data. We model the logarithm of expenditures and consider five different models. The first two are two-part and sample selection cross-section models. Two-part panel data models turn out to be inappropriate for...

This document presents the different ways to model heterogeneity in case of clustering, such pupils achievement in classroom or schools. In the linear framework, it essentially discusses the pertinence of fixed or random effects assumptions depending upon the goal pursued and the empirical...

Disentangling state dependence from unobserved heterogeneity is a common issue in economics. It arises for instance when studying transitions between different states on the labor market. When the outcome variable is binary, one of the usual strategies consists in using a conditional logit model...

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...

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...

This paper shows how to simply compute one of the estimators proposed by Honoré and Kyriazidou (2000), as well as its variance, through a reshaping of the original dataset that is then used in a weighted logistic regression with clustering.

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....

[fre] La Nouvelle économie géographique consacre la métropole comme « locomotive de la croissance économique ». L’espace devient un facteur crucial de la croissance du fait de l’existence d’économies d’agglomération minimisant les coûts de transaction. La littérature...

In this paper, we build a new test of rational expectations based on the marginal distributions of realizations and subjective beliefs. This test is widely applicable, including in the common situation where realizations and beliefs are observed in two different datasets that cannot be matched....
