A key aspect defining the contemporary income distribution is the (increasing) share the top holds compared to the rest. This paper shows that income concentration increases towards the very top of the distribution, while the shares the middle- and upper-middle-income groups hold remain stable...

This paper introduces in statistics the notion of the barycenter of the distribution of a non-negative random variable Y with a positive finite mean μY and the quantile function Q(x). The barycenter is denoted by μX and defined as the expected value of the random variable X having the...

This paper measures high medical expenses in ten developed countries, both overall and by income and age, providing some of the best evidence to date on the extent of high medical spending across and within countries. Using comparable household-level data on out-of pocket (OOP) medical...

Economic inequality across Asia has been growing, but dimensions of this inequality and their development are unclear. This paper evaluates income inequality using household surveys from China, India, Japan, Korea, Russia and Taiwan. These countries may be viewed as jointly representative of...

This paper provides recent evidence on the contribution of the spatial dimension to inequality and more specifically accounts for the impact of the changes in the territorial distribution of the population on the recent dynamics of income inequality. We use LIS harmonized microdata for a...

We provide a characterization of the generalised satisfaction - in our terminology nondeprivation - quasi-ordering introduced by S.R. Chakravarty (Keio Economic Studies 34 (1997), 17-32) for making welfare comparisons based on the absence of deprivation. We show that the non-deprivation...

Income distribution is seen as instrumental to human development and to a number of development outcomes through a variety of channels. It is also considered important in itself, as testified by its inclusion in the Sustainable Development Goals. Yet existing research on income inequality in...
