This paper analytically investigates the incentive scheme of perpetrators of violent conflicts. It provides a rational equilibrium framework to elicit how monetary incentives and survival considerations shape a combatant’s decision to participate in a conflict. In the model, a leader decides...

Au total, il semble bien que nous puissions conclure qu’à l’échelle nationale la mise en place de la loi Scellier a entraîné une hausse des prix du prix du mètre carré de l’ordre de 3 euros la première année et de 6 euros sur 2009 et 2010. Si l’on raisonne en termes de taux de...

We study cycles and chaos in economic models. Autonomous dynamical systems are considered through infinite time horizon optimization models. We first show how endogenous fluctuations arise in a multisector growth model. Secondly, we consider an extension of this model by allowing direct...

We consider the labour market implications of skill decay. State dependence in individual hazards emerges from the joint result of (optimal) hiring and search behaviours. We shed light on an original externality according to which firms' profits increase with the valuation of vacancies....

We adress the issue of optimal growth when standard-of-living aspirations are transmitted from one generation to the next. We derive the condition for the optimal solution to be stable in the saddle-point sense and show that this optimal solution may display damped oscillations even when the...

This paper constructs an overlapping generations model of pollution externality wherein individuals are altruistically linked to their offspring as in Barro (1974). It is shown that steady state consumption may be a decreasing function of the intergenerational degree of altruism. Despite...
