In an economy with a non-convex production sector, we provide an assumption on each individual producer, which implies that the survival assumption holds true at the aggregate level for general pricing rules. For the marginal pricing rule, we derive this assumption from the bounded marginal...

This paper focuses on the influence of the influence of the opening of a market of allowances, such as the European Union Emission Trading Scheme, on the general equilibrium of an economy. Assuming there existed an equilibrium before the opening of this new market, we describe the changes in the...

In this paper we prove an index formula for production economies with externalities. We allow for non-convexities in the production sector and set the firms behavior according to general pricing rules. We derive as corollaries existence of a general equilibrium in such a setting.

The measurement of gender inequalities has become an important topic in the academic literature. First, appropriate indicators are needed to compare the relative situation of women in developing countries. Second, there is renewed attention given to the relationship between gender inequality and...

This paper provides evidence that local social interactions within etnic groups may explain the puzzling variations in labour-market outcomes across individuals. Peer effects work first by creating pressure on labor-market participation, second, by conveying information about job opportunities...

This paper provides historical and empirical arguments that can explain the development of the Egyptian informal sector. After recalling the various approaches proposed in the literatures, it identifies the configuration that overrides the Egyptian labor market by allowing for the heterogeneity...

This paper assumes that gender inequality hinders economic and human development: a one standard deviation change in the Gender Inequality Index (GII) will increase long term income per capita by 9,1% and Human Development Index (HDI) by 4%. Gender inequality may be a explanation of economic...

By trying to guarantee that the fight against poverty is based on evidence, randomized experiments, essentially developed by Esther Duflo within the J-PAL, offer a new way to fight poverty. The originality of such approach is to import the methodology of clinical trials in development economics....
