Statistical analysis of inequality with decompositions: the Canadian experience
TLDR
The authors carried out a decomposition of Theil-entropy measures into a between-group component, based on factors such as education, age, gender, and marital status, and a component representing inequality within each group.Abstract:
This study carries out a decomposition of Theil-entropy measures into a between-group component, based on factors such as education, age, gender, and marital status, and a component representing inequality within each group. We apply a bootstrapping technique to measures of inequality to enable statistical inference. Trends in household income inequality in Canada are investigated using data from 1991 to 1997 drawn from Survey of Consumer Finance. We find an evident trend toward increasing inequality of household incomes between the years 1991–1997, during which the economy was recovering from a steep recession. Although most of the increase in measured inequality is attributed to the `within-group' component, we find the change in `between-group' inequality to be significant for education, age, and marital status.read more

Urbanization, Educational Expansion, and Expenditures Inequality in Indonesia in 1996, 1999, and 2002
Takahiro Akita,Sachiko Miyata +1 more
TL;DR: In this paper, the authors examined inequality changes associated with urbanization and educational expansion in Indonesia and found that the urban sector's higher educational group contributed significantly to overall inequality, leading to a conspicuous rise in urban inequality.

Earnings Variability and Earnings Instability of Women and Men in Canada: How Do the 1990s Compare to the 1980s?
TL;DR: In this paper, the authors decompose the total variation of workers' earnings into permanent variation and a transitory component (or earnings instability), and find that there has been an increase in overall earnings variability among Canadian workers between the two sub-periods, with the increase much more marked among men, particularly with non-continuous labour market attachment.

A Convenient Method of Decomposing the Gini Index by Population Subgroups
TL;DR: This paper proposed a method of estimating the within-group, between-group and interaction components of the overall traditional Gini index from the estimated parameters of underlying "trick regression models" involving known forms of heteroscedasticity related to income.

On the Measurement of Inequality
TL;DR: In this paper, the problem of comparing two frequency distributions f(u) of an attribute y which for convenience I shall refer to as income is defined as a risk in the theory of decision-making under uncertainty.

The Bootstrap and Edgeworth Expansion
TL;DR: In this paper, the authors present a non-Edgeworth view of the Bootstrap and propose a method of importance sampling for estimating bias, variance, and skewness.

Divergent inequalities: theory and empirical results
TL;DR: In this article, the authors show that widely used summary measures of inequality or the idea of the "disappearing middle class" are potentially misleading by failing to distinguish between the concepts of inequality and polarization, and using scalar "inequality" measures which are not consistent with rankings based on Lorenz curves.
