This paper proposes a method to decompose earnings inequality into a component due to unequal opportunities and a residual term. Drawing on the distinction between 'circumstance' and 'effort' variables in John Roemer's work on equality of opportunity, we associate inequality of opportunities...

This paper contributes towards the growing debate concerning the world distribution of in- come and its evolution over that past three to four decades. Our methodological approach is twofold. First, we formally test for the number of modes in a cross-sectional analysis where each country is...

We estimate and analyze the global income distribution from national log-normal income distributions for the years 1970 to 2003, as well as the income distribution of seven regional subsamples. From these distributions we obtain measures for global and regional inequality and poverty, and find...

In this paper we analyze the world´s cross-national distribution of income and its evolution from 1970 to 2003. We argue that modeling this distribution by a finite mixture and investigating its number of components has advantages over nonparametric inference concerning the number of modes. In...

Using the evidence from the Luxembourg Wealth Study it appears that the distribution of wealth in the UK is considerably less than in Canada, the US or Sweden. But does this result come from an underestimate of inequality among the wealthy and of the wealth differential between the rich and the...

We show how classic source-decomposition and subgroup-decomposition methods can be reconciled with regression methodology used in the recent literature. We also highlight some pitfalls that arise from uncritical use of the regression approach. The LIS database is used to compare the approaches...

We examine the relationship between risk analysis and inequality analysis, using a questionnaire-experimental approach .The experiments focus on the effect of income transformations on the perceived rankings of income distributions in either a risk or inequality context. Both context and income...

The amp;apos'prediction approachamp;apos' proposed by Dearden, Machin and Reed (DMR) consists in (1) regressing the observed incomes of the child and parent families on separate sets of predetermined variables, and (2) regressing the childamp;apos's predicted income on that of the parents....

We examine the sensitivity of estimates and inequality indices to extreme values, in the sense of their robustness properties and of their statistical performance. We establish that these measures are very sensitive to the properties of the income distribution. Estimation and inference can be...
