With address to developing countries, this paper derives some formulae for the optimal price structure for publicly provided private goods. A general equilibrium model is examined, which makes it possible to incorporate features like distributional social objectives and public profit constraints...

Interest in the emergence of a global middle class has resulted in a number of attempts to identify and enumerate who belongs to it . Current research provides wildly different estimates about the size and evolution of the global middle class because of a lack of consensus on appropriate...

Particularly in sub-Saharan Africa, agriculture is predominantly rain-fed and, therefore, prone to unstable weather conditions and less productive than in other regions of the world. Increasing the efficiency and sustainability of farmer groups and cooperatives is of primary importance to many...

This paper is concerned with concepts - poverty, inequality, affluence, and polarization - that are typically treated in different literatures. Our aim here is to place them within a common framework and to identify the way in which different classes of income transfers contribute to different...

Do market-orientated economies with relatively large cross-sectional levels of inequality have higher income mobility and therefore less permanent inequality? To answer this question, we introduce a formal representation of income mobility as an equalizer of permanent income. The proposed...

This paper is concerned with the problem of ranking and quantifying the extent of deprivation exhibited by multidimensional distributions, where the multiple attributes in which an individual can be deprived are represented by dichotomized variables. To this end we first aggregate deprivation...

In seeking to understand inequality today, a great deal can be learned from history. However, there are few countries for which the long-run development of income inequality has been charted. Many countries have records of incomes, taxes and social support. This paper presents a new methodology...

It is shown that if social welfare is the sum of logaritmic utility function, the optimal income distribution and the welfare effect of any income redistribution is independet of the equivalence scales. In optimum all households have the same per capita income. Based on this observation it is...
