We propose graphical methods to determine whether commodity-tax changes are "socially efficient", in the sense of improving social welfare or decreasing poverty for large classes of social welfare and poverty indices. We also derive estimators of critical poverty lines and economic efficiency...

This paper aims to test empirically if certain frequently used measures of well-being, which are regarded as valuable properties of human life, are actually desired by people. In other words, it investigates whether the "expert judgments" in social science overlap with social consensus on what...

This paper studies poverty as a dynamic phenomenon, motivated by the recurringeconomic crises that affect developing countries and the incidence of income fluctuationson household welfare. While the increasing availability of household panel data has beenexploited in theoretical analysis and...

What are the principal issues on which research on income distributionand inequality focus? How might that focus shift in the immediate future?Prepared for the The Elgar Handbook of Socio-Economics.

This article provides a brief overview of the key issues in inequality measurement andhas been prepared for inclusion in the second edition of The New Palgrave.

We examine individuals' distributional orderings in a number of contexts. This is done by using a questionnaire-experiment that is presented to respondents in any one of seven "flavours" or interpretations of the basic distributional problem. The flavours include inequality, risk, social welfare...

Starting from the axiomatisation of polarisation contained in Esteban and Ray (1994)and Chakravarty and Majumdar (2001) we investigate whether people's perceptionsof income polarisation is consistent with the key axioms. This is carried out using aquestionnaire-experimental approach that...

The evaluation of social risk equity for alternative probability distributions over the potential sets of fatalities is analyzed axiomatically. Fishburn and Straffin [Equity considerations in public risks valuation, Operatons Research 37 (1999), 229-239] have identified a necessary and...

We examine the statistical performance of inequality indices in the presence of extreme values in the data and show that these indices are very sensitive to the properties of the income distribution. Estimation and inference can be dramatically affected, especially when the tail of the income...

We consider a model with two types of consumers, with each preferring a different variety of goods, and with each better at producing the type of good it prefers to consume. We find that under plausible conditions members of the majority group earn a higher wage and enjoy higher utility than...
