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...

Although Foreign Direct Investments (FDI) are as important to the world economy as exports, the extensive literature on trade costs has no strong parallel for FDI. Data are hard to come by, and many of the barriers to FDI are unobservable. This paper circumvents the problem by inferring the...

In this paper, we analyze the effect of Cournot competition with differentiated products on the real and financial decisions of a publicly-owned firm, with three different structures in the financial market : monopoly, duopoly and Stackelberg. We shows that the degree of product differentiation...

Buyers are typically unaware of the full set of offers when making a purchase. This paper examines how international trade interacts with this problem of market intransparency. Sellers must communicate their offers through costly advertising, but cannot reach all buyers. Consequently, no market...
