This paper introduces a new Lorenz dominance criterion that allows ranking income distributions according to ray-invariant intermediate inequality measures. In doing so, it defines a-Lorenz curves by adapting the generalized Lorenz curves to this case. In addition, it provides an empirical...

This paper examines how spatial price differentials affect income distribution in Italy. The distribution of household income is “reshuffled” after controlling for the purchasing power of households residents in different regions, but only when housing price variations are included in the...

This study validates the microeconomic model defining the evolution of personal incomes in the U.S. Because of a large portion of population not reporting any income, any comprehensive modeling of the overall personal income distribution (PID) is complicated. Age-dependent PIDs allow overcoming...

Inequality measures are often presented in the form of a rank ordering to highlight their relative magnitudes. However, a rank ordering may produce misleading inference, because the inequality measures themselves are statistical estimators with different standard errors, and because a rank...

The evolution of Gini coefficient for personal incomes in the USA between 1947 and 2005 is analyzed and modeled. There are several versions of personal income distribution (PID) provided by the US Census Bureau (US CB) for this period with various levels of resolution. Effectively, these PIDs...

This paper introduces a class of intermediate inequality indices, I(?, ?), that is at the same time ray-invariant and unit-consistent. These measures permit us to keep some of the good properties of Krtscha’s (1994) index while keeping the same “centrist” attitude whatever the income...

The average and median income dependence on work experience and time is analyzed and modelled for the USA. The original data set providing the mean and median income estimates in 10 year long intervals spans a long time period of almost 35 years – from 1967 to 2003. A microeconomic model...

An income inequality measure satisfies the Pigou-Dalton transfer principle if progressive transfers decrease income inequality. When transfers cause transaction costs, one can trace out the maximum leakage such that the transfer pays at the margin. An income inequality measure is leaky-bucket...

We offer a model of equality of opportunity that encompasses different conceptions expressed in the public debate. In addition to circumstances whose effect on outcome should be compensated and eort which represents a legitimate source of inequality, we introduce a third factor, luck, that...

In contrast to the experience in high-income OECD countries, the introduction of democracy in most low- and middle-income countries (LMICs) has been followed, as a rule, by a concentration of income. Using the median voter hypothesis as analytical tool, this paper explores the conditions under...
