Labour market analysis is an important element to understand the inequality and poverty within a given population. The literature reveals that the informal sector is characterised by a great deal of flexibility and exempt from formal market rigidities but on the other hand, this sector can...

Growth of the informal sector of the Senegalese economy may result in a productivity slowdown and could induce a surge in inequality and poverty. The production process is similar for some subsectors of the informal sector and those of the formal one. But there is evidence that the economy is...

Based on empirical facts, we build a model of informal insurance institutions and study their stability. In our setting, risk sharing groups are overlapping homogenous coalitions, originating from networks of historical trust relationships. We derive a general folk theorem that works in an...

Four axioms are introduced in order to characterize the family of pair-based decomposable inequality measures, which is embraced in the class of weakly decomposable inequality measures. Three axioms, namely, normalization by pairs, aggregation by pairs, and decomposition by pairs enable the...

This paper analyzes the definition of economic efficiency. The standard definition used in economic literature is the Pareto Optimum which is based in the space of individual utilities. This paper proposes new definitions based on alternative spaces. The paper also introduces a dominance...

La littérature montre que la mesure des inégalités de revenu n’est pas suffisante pour appréhender les déterminants des inégalités. Les sources de rémunération, leurs corrélations au revenu global, leurs parts dans le revenu global, rentrent en compte dans la décomposition de la...

An axiomatic approach is used to propose a measure of extreme poverty which is not only multidimensional in nature, but also recognizes the fact that there are interaction effects between different deprivations, and that the length of time during which deprivations are felt may also have a...

The concept of horizontal inequality is generally used in economics to refer to the unequal treatment of equal individuals by the fiscal system. For example, an economic system can treat unequally two individuals who hold identical levels of production factors. The following note will present a...

We propose simple graphical methods to identify poverty-reducing marginal reforms of transfer programs. The methods are based on Program Dominance curves that display cumulative program benefits weighted by powers of poverty gaps. These curves can be decomposed simply as sums of targeting...

In this paper we construct a standard CGE model to explore the impact of scaling up infrastructure in Mali. As the debate on the importance of scaling up infrastructure to stimulate growth and provide a push to African economies, some analyst raise concern on financing these infrastructures...
