The aim of this paper is to provide a detailed analysis of the process of segregation formation. The claim is that segregation does not originate from prejudice or exogenous psychological factors. Rather it is the product of strategic interactions among social groups in a setting where one group...

The paper aims to present the insurance linked securities market behaviour, that has changed a lot the past three years, both in terms of structure and in terms of ceded risks. After having introduced some stylized facts characterizing the insurance linked securities we capture their market...

This papier formalizes the process of forecasting unbalanced monthly data sets in order to obtain robust nowcasts and forecasts of quarterly GDP growth rate through a semi-parametric modelling. This innovative approach lies on the use on non-parametric methods, based on nearest neighbors and on...

The main contribution of the paper is to provide a weaker non-satiation assumption than the one commonly used in the literature to ensure the existence of competitive equilibrium. Our assumption allows for satiation points in the set of individually feasible consumptions, provided that the...

We study in this paper the interactions between migration rates and the level of labour standards. We use an augmented version of the Grogger and Hanson (2008) model, adding the level of working conditions into the specification. Our hypothesis is that the differential of working conditions may...

In Cameroun, around 18 percent of children aged between 10-14 years old grow up within a sibship extended to host one (or more) foster-child. This proportion is similar in other African countries and in particular West African ones. This paper aims at estimating the effect of foster-children...

The financial and economic crisis entails the question of a return to organized societal regulation. After 30 years during which public authority occupied a marginal position, the financial world is begging for a return to some order. Thus, the question to be asked is that of the legitimate...

Eliciting sincere preferences for non-market goods remains a challenge due to hypothetical bias - the so-called gap between hypothetical monetary values and real economic commitments. The gap arises because people either overstate hypothetical values or understate real commitments or a...

We study the structure of unstable local effectivity functions defined for n players and p alternatives. A stability index based on the notion of cycle is introduced. In the particular case of simple games, the stability index is closely related to the Nakamura Number. In general it may be any...

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...
