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

We show how a collection of results in the literature on the empirical estimation of welfare indicators from sample data can be unified. We also demonstrate how some of these ideas can be extended to empirically important cases where the data have been trimmed or censored.

Orderings of income distribution in terms of inequality should be closely related to orderings in terms of risk. Using a novel mult-country questgionnaire experiment we examine the basis for this claim in terms of respondents' distributional perceptions. We show that in terms of both inequality...

According to standard theory founded on Harsanyi (1953, 1955) a social welfare function can be appropriately based on the individual’s approach to choice under uncertainty. We investigate whether people really do rank distributions according to the same principles irrespective of whether the...

We stablish a general relationship between the standard form of the individualistic social-welfare function and the "reduced-form" version that is expressed in terms of inequality and mean income. This shows the relationship between the property of monotonicity and the slope of the...

Lorenz curves and second-order dominance criteria are known to be sensitive to data contamination in the right tail of the distribution. We propose two ways of dealing with the problem: (1) Estimate Lorenz curves using parametric models for income distributions, and (2) Combine empirical...

The analysis of inequality is placed in the context of recent developments in economics and statistics. Prepared for Handbook of Income Distribution, edited by A B Atkinson and F Bourguignon.

Inequality comparisons between countries and over time should take into account problems of data imperfection. We examine the contrasting experience of the UK and Spain during the 1980s in terms of the distribution of disposable income. We consider whether the apparent divergence in inequality...

Poverty and inequality are often estimated from grouped data as complete household surveys are neither always available to researchers nor easy to analyze. In this study we assess the performance of functional forms proposed by Kakwani (1980a) and Villasenor and Arnold(1989) to estimate the...
