The main objective of this study is to analyse the effect of the professional environment on sick leaves. The professional context is approximated by the sector of activity. The database used - Hygie (2005-2008) - allows taking individual heterogeneity into account thanks to the longitudinal...

In this note, I study further a new approach recently introduced for the hedging of derivatives in incomplete markets via non quadratic local risk minimization. A structure result is provided, which essentially shows the equivalence between non-quadratic risk minimization under the historical...

La gouvernance de la Compagnie de Jésus se caractérise dès ses débuts par un certain nombre de particularités, dont le vœu d'obéissance au pape, l'importante autorité du préposé général, ainsi que l'esprit ignatien qui est transmis à travers les exercices spirituels à toutes les...

There is considerable debate whether the domestic political institutions (specifically, the country's level of democracy) of the host developing country toward foreign investors are effective in establishing the credibility of commitments are still underway, researchers have also analyzed the...

We consider an optimal investment and consumption problem for a Black-Scholes financial market with stochastic volatility and unknown stock appreciation rate. The volatility parameter is driven by an external economic factor modeled as a diffusion process of Ornstein-Uhlenbeck type with unknown...

The aim of the article is to contribute to the analysis of path dependency mechanisms at territory level in old industrial regions. The paper presents the results of research into the processes of transition that have been at work over the past 25 years in two old French clusters. In these...

We present a model of inductive inference that includes, as special cases, Bayesian reasoning, case-based reasoning, and rulebased reasoning. This uni ed framework allows us to examine how the various modes of inductive inference can be combined and how their relative weights change...

In 2003, the French government decided to reform the system managing the different minimum wage regulations and the targeted reductions to employers' social security contributions. The main objective of the reform was to simplify the complex regulations that were created by the progressive...

We defend a methodology of discounting, for the evaluation of the long-term effects of climate policies, which relies on a social welfare objective, against the view that the market rate of return should be used for that purpose. We also show that in the long run, the discount rate for such...

We study the influence of taking liquidity costs and market impact into account when hedging a contingent claim, first in the discrete time setting, then in continuous time. In the latter case and in a complete market, we derive a fully non-linear pricing partial differential equation, and...
