We develop a model economy adapting Hotelling's migration law to make individuals react to the gradient of their indirect utility. In a first version, individuals respond uniquely to utility differences. In a second phase, we insert our migration law as a dynamic constraint in a spatial model of...

This paper focuses on jobs found by formerly unemployed people ; it is based on the 2007 and 2009 « leaving unemployment » surveys. A review of recent studies about job quality shows the importance of multi-dimensional approaches. Yet few research works are concerned with job quality of...

Financial globalization has led to the explosion of the principle of societal regulation applied by the political domain considered as inoperative, in order to be taken over by civil society. This is the dogma of ungovernability. Civil society, proclaiming its expertise, does nevertheless affirm...

This article presents a conceptual approach related to the European flexicurity debate, the Transitional Labour Market (TLM) theory and its main assumptions. The aim is to bring this analytic framework into the discussion and to clarify some central aspects by defining the key concepts of...

In this paper we propose new option pricing models based on class of models with jump contain in the Lévy-type based models (NIG-Lévy, Merton-jump (Merton 1976) and Duan based model (Duan 2007)). By combining these different class of models with several volatility dynamics of the GARCH type,...

Two financial structures are equivalent if, for each given state price, the images of their full payoff matrices of these financial structures are equal. The main consequence of this definition is that, regardless of the standard exchange economy ?, the existence of a financial equilibrium in an...

We consider a stochastic financial exchange economy with a finite date-event tree representing time and uncertainty and a financial structure with possibly long-term assets. We exhibit a sufficient condition under which the set of marketable payoffs depends continuously on the arbitrage free...

This working paper proposes an analysis – from a Marxist point of view – of the relationships between John Maynard Keynes and the economic mainstream of his time (first part), then presents the theoretical elements on the crisis developed by this author (second part), and finally questions,...
