In this paper, we consider a simple kinetic model of economy involving both exchanges between agents and speculative trading. We show that the kinetic model admits non trivial quasi-stationary states with power law tails of Pareto type. In order to do this we consider a suitable asymptotic limit...

Depuis plusieurs années, les entreprises préfèrent les bureaux ouverts aux bureaux individuels. Pourtant, l'open space a souvent été critiqué par les salariés et notamment par deux salariés dans le livre L'open space m'a tuer. Malgré ces critiques, les entreprises privées snobent...

Dans cette communication, nous essayons de montrer que de nombreux instruments du contrôle de gestion semblent céder a une idéologie de la complexité. Ceux-ci semblent en effet invoquer la complexité et leur capacité a aider les managers à la prendre en charge sans pour autant réellement...

There are two main approaches for defining social welfare relations for an economy with infinite horizon. The first one is to consider the set of intertemporal utility streams generated by a general set of bounded consumptions and define a preference relation between them. This relation is...

This paper inverts the usual logic of applied optimal income taxation. It starts from the observed distribution of income before and after redistribution and corresponding marginal tax rates. Under a set of simplifying assumptions, it is then possible to recover the social welfare function that...

This paper presents the Paretian Watershed and the fundamental theorems of welfare economics. It distinguishes the British approach (à la Kaldor-Hicks) from the American approach (à la Bergson-Samuelson) to new welfare economics. It develops the more recent domains of happiness economics, the...

There is no consensus yet on the correct way to write the social utility function in presence of paternalistic altruism. This note shows that the speci cation of the central planner objective is crucial for optimal capital intensity and optimal growth in a one and a two-sector models. In a...

Few studies have explored, to date, the issue of the monetary valuation of non-fatal injuries caused by road traffic accidents. The present paper arises interest in this question and aims to estimate, by means of the contingent valuation, the willingness to pay (WTP) of French households to...
