Income distributions for developing countries in Asia are modeled using beta-2 distributions, which are estimated by a method of moments procedure applied to grouped data. Estimated parameters of these distributions are used to calculate measures of inequality, poverty, and pro-poor growth in...

Similar looking Lorenz Curves can imply very different income density functions and potentially lead to wrong policy implications regarding inequality. This paper derives a relation between a Lorenz Curve and the modality of its underlying income density: Given a parametric Lorenz Curve, it is...

This paper studies the stationary distribution of wealth by using a basic economic model encompassing saving, investment, occupational choice, an imperfect credit market, entrepreneurial abilities, and intergenerational wealth mobilities. It implies that persistent wealth inequality depends on...

The generalized entropy class of inequality indices is derived for Generalized Beta of the Second Kind (GB2) income distributions, thereby providing a full range of top-sensitive and bottom-sensitive measures. An examination of British income inequality in 1994/95 and 2004/05 illustrates the...

Income distribution analysis can be conducted from the point of view of the comparisons between different geographical regions, family types or socio-economic groups it can also be carried out to assess the effects of an economic policy over time. The paper presents the results of a research on...

This paper revisits the fitting of parametric distributions to earned income data. In line with Camilo Dagum's dictum that candidate distribution should not only be chosen for fit, but that economic content should also play a role, a new candidate is proposed. The fit of a simple finite mixture...

In this paper, income distributions for developing countries in Asia are modeled using beta-2 distributions, which are estimated by a method of moments procedure applied to grouped data. Estimated parameters of these distributions are used to calculate measures of inequality, poverty, and...

Growth that reduces poverty is often considered pro-poor regardless of whether the poor benefit from it more than the non-poor. Such growth could simply be termed poverty-reducing growth. This paper argues that for growth to be pro-poor it should disproportionally benefit the poor. The paper...

This article proposes the k-generalized distribution as a descriptive model for the distribution and dispersion of income within a population based on the deformed exponential and logarithm functions recently introduced by Kaniadakis (Phys A 296:405–425, 2001; Phys Rev E 66:056125, 2002; Phys Rev E...

Poverty and inequality are often estimated from grouped data as complete household surveys are neither always available to researchers nor easy to analyze. In this study we assess the performance of functional forms proposed by Kakwani (1980a) and Villasenor and Arnold (1989) to estimate the...
