Yet, it may give rise to a strong endogeneity problem since the use of a proxy respondent is likely to be linked to subjects’ health status. That paper aims at giving a convenient and tractable way to cope with the twofold potential endogeneity of the respondent status in the estimation of two probit equations concerning the need for care with daily activities and unmet or undermet need reported by people aged 60 years and over living in the community. Unlike previous papers dealing with that topic, evidence is found that proxy respondents do not entail any subjectivity when they assess old people’s need for care but they seem to overestimate undermet and unmet need.

Ces formes atypiques d’emploi concernent en premier lieu la jeunesse et peuvent constituer un prealable a une insertion durable ou laisser des cicatrices sur leurs chances d’emploi a moyen terme. Nous comparons les trajectoires d’entree sur le marche du travail de cohortes de primo-sortants du systeme educatif de 1998, 2004 et 2010 a l’aide d’un modele dynamique markovien de transitions heterogenes sur le marche du travail. Nos analyses montrent que la norme d’emploi est de plus en plus difficile a atteindre. Les evolutions recentes des dynamiques de transitions sur le marche du travail, en lien avec la crise de 2008, apparaissent fortement heterogenes. Elles ont contribue a compenser la degradation tendancielle des effets tremplin de l’emploi a temps complet en CDD vers le CDI a temps complet.

Extending it to commonly used nonlinear models such as binary choice and duration models is not straightforward. This paper shows that the original decomposition using a linear model can be obtained as a first order Taylor expansion. This basis provides a means of obtaining a coherent and unified approach which applies to nonlinear models, which we refer to as a Taylor decomposition. Explicit formulae are provided for the Taylor decomposition for the main nonlinear models used in applied econometrics including the Probit binary choice and Weibull duration models. The detailed decomposition of the explained component is expressed in terms of what are usually referred to as marginal effects and a remainder. Given Jensen's inequality, the latter will always be present in nonlinear models unless an ad hoc or tautological basis for decomposition is used.

The aim of this study was to compare Progression Free Survival (PFS) at 1st line treatment of EOC patients treated in high vs low-volume hospitals. This retrospective study using prospectively implemented databases was conducted o n an exhaustive cohort of 267 patients treated in first line during 2012 in the Rhone-Alps Region of France. In order to control for selection bias, a multivariate analysis and the Inverse Probability Weighting (IPW) using the propensity score were adopted. An Adjusted Kaplan Meier Estimator (AKME) and a univariate Cox model in the weighted sample were then applied in order to determine the impact of the centralization of care on EOC. Patients treated in lower volume hospitals had a probability of relapse (including death) that was 1.5 times higher than for patients treated in higher volume hospitals (p=0.02). As reported in other countries, the concentration of care for EOC has a significant positive impact on patient outcomes .
