Gini and entropy are the most use measures to gauge income inequalities. We show that each measure yields different subgroup decomposition techniques into within-group inequalities and between-group inequalities. Then, we show that the Gini index has been decomposed into many ways to bring out a...

L’objet de cet article est de vérifier si les facteurs d’insécurité alimentaire qui exercent une influence clé en milieu urbain ont un impact tout aussi significatif en milieu rural au Sénégal. A cette fin, un modèle logit binomial appliqué aux données de l’enquête ménage du...

In this paper, we suggest a framework for the analysis of ethnic polarization. This framework allows for the measurement of ethnic or religious polarization. We apply our measure to Ivory Coast and find a surprising result as the ethnic polarization decreased in years preceding the conflict in...

Parental migration is often found to be negatively correlated with child health in Africa, yet the causal mechanisms are poorly understood. The paper uses a dataset that provides information from the respondent parent on child morbidity both in the rural and urban settings. Households first...

Empirical studies point to trade credit as an important continuing source of short term financing for small and medium-sized enterprises. We show that vendor financing appears in equilibrium as the result of repeated trade interactions between a buyer and a supplier when changing supplier is...

Welfare comparisons may be sensitive to the assumptions made about economies of scale within households. This paper uses recent advances in sequential stochastic dominance techniques to show how to test for the robustness of poverty and housing quality comparisons to assumptions about economies...

The OECD estimates that between 1970 and 1995 more than half of the total growth in output of the developed world resulted from innovation, and the proportion is increasing as the economy becomes ever more knowledge intensive (European Commission, 2001). Protection of intellectual property is...

Decentralization of expenditure responsibilities from central to local governments is generally thought to increase overall government accountability by bringing the policymaking process closer to citizens. In practice, decentralization reforms tend to be partial in nature, leading to the...

Using an extension of Lucas' model of endogenous growth with education externality, we show that an environmental tax may increase growth. This is because the tax makes physical capital accumulation less attractive, thereby correcting for the underinvestment by agents in human capital.
