This paper develops a simple model of optimal growth with renewable resource and endogenous discounting. Relaxing the time-additivity preference hypothesis allows to make endogenous the rate of time preference and to reconsider the dynamics of models with concave resource. The possibility of...

The aim of this paper is to analyse how the criteria of horizontal and vertical equity of the French system of family transfers evolved from 1975 till 2002. It focuses primarily on non-contributory benefits and on income taxation and uses family type's methods. Two main findings can be outlined...

Beyond the presupposed cleavage between economics and ethics, the institutional dimension of economic ethics is to the emphasized. The question is : how can we define collective legal rules which concern the whole society ? The other great issue of ethics formalization is then the implementation...

In a general equilibrium model of incomplete nominal-asset markets and adverse selection, Cornet-De Boisdeffre [3] introduced refined concepts of " no-arbitrage " prices and equilibria, which extended to the asymmetric information setting the classical concepts of symmetric information. In...

We propose in this note a simple non-parametric test of Richter-rationality which is the basic definition of rationality used in choice functions theory. Loosely speaking, the data set is rationalizable in the Richter' sense if there exists a complete-acyclic binary relation that rationalizes...

We give some Fubini's theorems (interversion of the order of integration and product capacities) in the framework of the Choquet integral for product sigma-algebras. Following Ghirardato this is performed by considering slice-comonotonic functions. Our results can be easily interpreted for...

We examine how spillovers can circulate. More precisely, we study how spillovers can flow inside cooperation. We first present the standard conception that considers spillovers are market failures. In that case, cooperation allows internalising them. As the internalisation is partial, we propose...

The European Union has decided to implement in 1999 an independent European security and defence policy (ESDP). As States' preferences in defence issues are characterized by a strong heterogeneity, I propose to determine the kind of allocation process for providing defence resources. By assuming...

This paper considers the role mergers and acquisitions have on employment. First, it considers the importance of different aspects of compensation policy and human resource management practices for distinguishing acquired and acquiring firms. Second, it examines which individuals from which...

We investigate the profitability and locational effects of two-firm Cournot mergers in the circular city. As compared with the linear market, we find that mergers turn out to be unprofitable much earlier.
