[eng] Two traditional assumption of dynamic demand models intertemporal separability and the recursivity of the utility function are here analyzed in detail .The kind of preferences underlying each utility function is first derived. We show that if separability easily accepts recursivity it is...

La théorie micro-économique entend réduire au maximum le nombre d'hy pothèses sur les goûts nécessaire à la construction des modèles de demande. Néanmoins aucun modèle n'atteint jamais la généralité absolue et certaines hypothèses sont même devenues tellement usuelles qu'on ne...

We study linear factor models under the assumptions that factors are mutually independent and independent of errors, and errors can be correlated to some extent. Under factor non-Gaussianity, second to fourth-order moments are shown to yield full identification of the matrix of factor loadings....

We develop and estimate an equilibrium job search model of worker careers, allowing for human capital accumulation, employer heterogeneity and individual-level shocks. Monthly wage growth is decomposed into the contributions of human capital and job search, within and between jobs. Human capital...

Postel-Vinay and Robin’s (2002) sequential auction model is extended to allow for aggregate productivity shocks. Workers exhibit permanent differences in ability while firms are identical. Negative aggregate productivity shocks induce job destruction by driving the surplus of matches with low...

We compare earnings inequality and mobility across the U.S., Canada, France, Germany and the U.K. during the late 1990s. A flexible model of earnings dynamics that isolates positional mobility within a stable earnings distribution is estimated. Earnings trajectories are then simulated, and...

Il existe une économie politique du redoublement dont il faut essayer de mettre à jour quelques ressorts : le redoublement est une modalité particulière de la gestion du système éducatif qui présente des coûts et des bénéfices et dont l’efficacité est mise en question depuis de...

We develop an empirical search-matching model with productivity shocks so as to analyze policy interventions in a labor market with heterogeneous agents. To achieve this we develop an equilibrium model of wage determination and employment, which is consistent with key empirical facts. As such...
