This paper provides an econometric evaluation of the impact of two innovative care programs for elderly people with dementia (day-care centers and group-living) on the well-being of the primary caregiver of patients. For this evaluation, we use data from a survey conducted in six European...

Des études empiriques montrent que dans les pays en voie de développement des chocs sanitaires peuvent avoir des effets sévères sur le revenu des ménages. Peu d’analyses ont jusqu’à présent analysé l’impact de la mortalité. La différence majeure entre une période de maladie et...

A partir de la Encuesta Salud, Bienestar y Envejecimiento (SABE) de la OPS-OMS (2001) se estiman los determinantes del estado de salud para los adultos mayores montevideanos (60 años y más). Se utilizan cuatro aproximaciones a dicho estado: limitaciones funcionales, autopercepción,...

This paper considers the identification and estimation of hedonic models. We establish that in an additive version of the hedonic model, technology and preferences are generically nonparametrically identified from data on demand and supply in a single hedonic market. The empirical literature...

Cet article propose une analyse des rendements éducatifs issue du modèle de Mincer (1974). Dans le cas de Madagascar où plus de 50% des élèves étaient scolarisés dans une école privée en 1997, le type d’éducation reçue (publique ou privée) est pris en compte, tandis que les biais...

Researchers, policymakers, and parents are giving education reforms involving expanded school choice increased attention. Many view the heightened competition that would presumably result from such reforms as a panacea for the ills currently plaguing the public education system in the US....

This paper develops Wald-type tests for general (possibly nonlinear) restrictions in the context of a weakly-identified heteroskedastic IV regression. In particular, it is first shown that, in a framework with many weak instruments, consistency and asymptotic normality can be obtained when...

This paper considers models with time-varying individual effects (also known as factor models). The paper extends Ahn, Lee and Schmidt, Journal of Econometrics, 2001 and Bai, Econometrica, 2003 to allow a parametric function of time for the time factor. It provides a fixed-effects treatment of...

This paper proposes shrinkage methods in instrumental variable estimations to solve the ``many instruments'' problem. Even though using a large number of instruments reduces the asymptotic variances of the estimators, it has been observed both in theoretical works and in practice that in finite...

Instrumental Variables (IV) methods identify internally valid causal effects for individuals whose treatment status is manipulable by the instrument at hand. Inference for other populations inevitably requires some sort of homogeneity assumption. I develop a simple theoretical framework that...
