We decompose the generalized Lorenz order into a size and a distribution component. The former is represented by stochastic dominance, the latter by the standard Lorenz order. We show that it is always possible, given generalized Lorenz dominance between two distributions F and G, to find...

We investigate how income inequality affects social welfare in a model of voluntary contributions to multiple pure public goods. Itaya, de Meza, and Myles (1997) show that the maximization of social welfare precludes income equality in a single pure public good model. In contrast, we show that...

The well known Pareto criterion used in the context of efficiency and welfare has to do with absolute changes whereas in every domain of economic behaviour inequality or relative changes has become a major concern. We propose an inequality-preserving or distribution neutral Pareto criterion-the...

Over the last decades, research in behavioural economics has demonstrated that individual welfare (utility), as relevant for economic decision making, depends not only on absolut but also on distributional aspects. Moreover, evidence is gathering that something similar holds for aggregate...

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...

This note provides evidence for the relationship between income comparisons and subjective well-being (SWB), using novel German data on self-reported comparison intensity and perceived relative income for seven reference groups. We find negative correlations between comparison intensity and SWB...

We estimate household equivalence scales using income satisfaction data from the German Socio-Economic Panel. We extend previous studies applying this approach by taking reference income into account. This allows separating needs-based from reference effects in the determination of income...

The present note raises the issue of how best to interpret the World Bank's (WB) much used "constant USD per capita income" concept and similar series. We find that the guide to its construction appearing on the WB data portal to be sketchy. The procedures essentially convert all host-country...

Recent books by Thomas Piketty (Piketty, 2014) and Anthony Atkinson (Atkinson, 2015) have brought the annual wealth tax back on the policy agenda. Both authors suggest using the annual wealth tax to supplement the redistributional effects of the income tax, assigning it a role as a...
