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 introduces in statistics the notion of the barycenter of the distribution of a non-negative random variable and explores its relation with the Gini index, the concentration area, and the Gini’s mean difference. The introduction of the barycenter allows for new economic, geometrical,...

This paper investigates whether the size of the shadow economy increases income inequality in Uganda. This paper applies the autoregressive distributed lag (ARDL) bounds testing approach to cointegration, to test the long- and short-run relationship between the shadow economy and income...

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...

Chotikapanich and Griffiths (2002) introduced the Dirichlet distribution to the estimation of Lorenz curves. This distribution naturally accommodates the proportional nature of income share data and the dependence structure between the shares. Chotikapanich and Griffiths (2002) fit a family of...

This paper adds to our understanding of the causes of income inequality across nations by examining the influence of different aspects of gender equality or female empowerment. Whereas the economics of income inequality has been an area of active academic inquiry, the role of gender equality has...

The Household Integrated Economic Surveys (HIES) of the Pakistan Bureau of Statistics (PBS) reveal a low level of income inequality in Pakistan. However, this is due to large sampling and non-sampling errors. Appropriate adjustments for the size and inequality in income from different sources...

This work studies trends in income distributions and inequality in the European Union using data from the European Union Statistics on Income and Living Conditions. We model the income distribution for each country under a Dagum distribution assumption and using maximum likelihood techniques. We...

The cohesiveness of constituent nations in a confederation such as the Eurozone depends on their equally shared experiences. In terms of household incomes, commonality of distribution across those constituent nations with that of the Eurozone as an entity in itself is of the essence. Generally,...

Recent research on Nigeria indicates declining income inequality. In contrast, anecdotal evidence suggests that only the upper class has benefited from economic growth in Nigeria overtime. The disconnect between these findings and anecdotal evidence, and the limitation in how inequality was...
