This paper derives a basic formula for the measure of social welfare, a second order approximation to the difference of the value of the Bergson-Samuelson social welfare function between the socially optimal resource allocation and the one in the present suboptimal economy. We discuss pros and...

I take a new approach to measuring world inequality and welfare over time by constructing robust bounds for these series instead of imposing parametric assumptions to compute point estimates. I derive sharp bounds on the Atkinson inequality index that are valid for any underlying distribution of...

The Gini coefficient features prominently in Amartya Sen's 1973 and 1997 seminal work on income inequality and social welfare. We construct the Gini coefficient from social-psychological building blocks, reformulating it as a ratio between a measure of social stress and aggregate income. We...

This paper asks whether prioritarianism - the view that social welfare orderings should give explicit priority to the worse-off - is consistent with the normative theory of equality of opportunity. We show that there are inherent tensions between some of the axioms underpinning prioritarianism...

There is no consensus on how to measure social welfare and inequality when households have different needs. As we show, a dilemma emerges between holding households responsible for their needs or compensating them. This dilemma is of first-order importance for social welfare, but generally plays...

When individuals' utility is a convex combination of their income and their concern at having a low relative income (the weights attached to income and to the concern at having a low relative income sum up to one), the maximization of aggregate utility yields an equal income distribution. This...
