This paper analyses the determinants of the Romanian temporary labour migration during the transition period. First of all, we build a househould level model in order to explain the decision to migrate in a couple. Then, by using a 10% sample of the Romanian 2002 Census we try to assess the...

This paper is organized as follows : First we show that the reference to the notion of group selection is coherent with the other parts of Hayek's thought. Second we develop the idea that recent works in terms of the emergence and evolution of social norms corroborate in part Hayek's theses in...

We present a model of household behavior to explore the complex interactions between the decision-making process within the household and social norms. The household is viewed as two separate spheres – the female and the male – both linked by a public good and a "conjugal contract" trough...

This paper investigates the relationship between the subjective well-being of both the employed and unemployed and regional unemployment rates. While employed men suffer from regional unemployment, unemployed men are significantly less negatively affected. This is consistent with a social-norm...

This paper proposes a new formulation of the theory of social norms. The theoretical model explores the interrelation between individuals' income, time-use and consumption decisions on the one hand, and the determinants of their decision to conform or not to social norms on the other. It is...

This article focuses on the three way relationship between change in divorce law, evolution of divorce rate and evolution of the cultural acceptance of divorce. We consider a heterogeneous population in which individuals differ in terms of the subjective loss they suffer when divorced, this loss...

While the opportunity to punish selfish and reward generous behavior coexist in many instances in daily life, in most laboratory studies, the demand for punishment and reward are studied separately from one another. This paper presents the results from an experiment measuring the demand for...

We deal with the problem of outsourcing the debt for a big investment, according two situations: either the firm outsources both the investment (and the associated debt) and the exploitation to a private consortium, or the firm supports the debt and the investment but outsources the...

In a recent but well known paper, Reny has proved the existence of Nash equilibria for compact and quasiconcave games, with possibly discontinuous payoff functions. In this paper, we prove that the quasiconcavity assumption in Reny's theorem can be weakened : we introduce a measure allowing to...

A power system is modeled by an interaction form, the solution of which is called a settlement. By stability we mean the existence of some settlement for any preference profile. Like in other models of power structure, instability is equivalent to the existence of a cycle. Structural properties...
