We provide the first theoretical analysis of altruism in networks. Agents are embedded in a fixed, weighted network and care about their direct friends. Given some initial distribution of incomes, they may decide to support their poorer friends. We study the resulting non-cooperative transfer...

We develop a dynamic game to provide with a theory of Arab spring-type events. We consider two interacting groups, the elite vs the citizens, two political regimes, dictatorship vs a freer regime, the possibility to switch from the first to the second regime as a consequence of a revolution, and...

In this paper, we conduct an econometric analysis of the links of on-the-job training (OJT) and worker remuneration in the area of Tunis using a case study data based on eight firms. We pay particular attention to the way the OJT cost may be shared between firms and workers. This is done through...

We explore the existence of endogenous fluctuations with a rational bubble and the stabilizing role of fiscal and monetary policies. Consumers' credit constraints, the role of collateral and a portfolio choice are the key ingredients of our analysis. We consider an overlapping generations model...

We estimate the informal-formal sector pay gap throughout the conditional wage distribution using panel data from Brazil, Mexico and South Africa. We control for time-invariant unobservables and identification is stemming from inter-sector movers. We control for observables in a non-linear way...

This paper provides a new estimation of an international poverty line based on a Bayesian approach. We found that the official poverty lines of the poorest countries are related to the countries' mean consumption level. This new philosophy is to be compared to the previous assumptions made by...

La plupart des modèles économiques d'indemnisation des dommages définissent le montant de l'indemnité proportionnellement à faute commise et laissent à la victime l'initiative de la démarche de négociation. Par opposition à ces systèmes de " tort law ", se développent des dispositifs...

A large body of theoretical and empirical research focuses on two very different rationales for government subsidies to college students: positive fiscal externalities from greater human capital accumulation and a larger income tax base, and the existence of liquidity constraints among student...

L'économie du bien-être ou welfarisme, qui pose que les seules informations pertinentes pour juger les états sociaux sont les utilités individuelles (Sen, 1979), a très longtemps occupé une place hégémonique dans le champ de l'économie normative. Le modèle ELIE de redistribution des...

This paper develops a simple business-cycle model in which financial shocks have large macroeconomic effects when private agents are gradually learning their uncertain environment. When agents update their beliefs about the parameters that govern the unobserved process driving financial shocks...
