Since von Neuman and Morgenstern's (1944) contribution to game theory, the expected utility criterion has become the standard functional to evaluate risky prospects. Risky prospects are understood to be lotteries on a set of prizes. In which case a decision maker will receive a precise prize...

Will employment instability be the employment pattern tomorrow? Many studies support this view. This analysis is first discussed. Statistical data don't allow concluding to a general trend of employment instability during the 80's. These data show that different figures of mobility have been...

This paper aims to show how the neo-classical current, which has yet absorbed development as one of its components, is trapped in a deep crisis, and how its domination can be understood in the theoretical field tightly linked to that of neo-liberalism on the policies of development.

This paper proposes a new empirical representation of inflation expectations errors in a Space-State Markov-Switching framework. We explicitly identify the dynamics of inflation expectation errors using the expectations augmented Markov-Switching Phillips curve as a measurement equation. In this...

This paper discusses various proposals to handle measures of flexicurity or lifelong learning. A critical reading of their theoretical foundations, and their consequences on the labour market is set out. The claim to give an answer to the unemployment by using these measures is contested. Having...

The question at stake is that of the theoretical representation of marketable permits. The setting up of such markets to regulate pollution problems is justified by constant reference to the efficiency of market coordination. Indeed, Montgomery established in 1972 the existence of an efficient...

Usually, an economic good isn't available gratuitously, but the case of information goods and services (IGS) is specific. Their intrinsic properties allow zero prices that is unconceivable for the others economic private goods. The gratuitousness is not the aim of productive activity ; it...
