Policy makers are generally interested in both the anti-poverty impact and the efficiency of reforms. To connect these two dimensions, I measure the poverty gap change per unit of net revenue that tax-benefit reforms produce. To isolate the impact of reforms and account for labour supply...

During the last 20 years, microsimulation models have been increasingly applied in qualitative and quantitative analysis of public policies. This paper discusses microsimulation techniques and their theoretical background as a tool for the analysis of public policies. It next analyses basic...

The key challenge in making distributional comparisons with ordinal data is the lack of commensurability of the distances between the ordered categories. This chapter provides a critical review of the most recent theoretical developments addressing this challenge and providing methods for...

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...

Assessing whether distributional changes are pro-poor has become increasingly widespread in academic and policy circles. Starting from relatively general ethical axioms, this paper proposes simple graphical methods to test whether distributional changes are indeed pro-poor. Pro-poor standards...

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 socialpsychological building blocks, reformulating it as a ratio between a measure of social stress and aggregate income. We...

This paper examines the fiscal and distributional effects of a number of alternative basic income implementation modes across 28 European welfare states. The paper aims to make three contributions to the literature. Firstly, through the use of EUROMOD's advanced 'add-on' and 'loop' features, we...

This paper aims to propose a social protection system that "decommodifies" labour and fulfills the properties of a Social Protection Floor satisfying revenue-neutrality. To this end, firstly, a Universal Basic Income (UBI) scheme is explored. Secondly, the UBI is transformed into a Negative...

This paper analyses the effectiveness of tax-benefit systems in reducing poverty and inequality across 13 countries in the Global South. Using national survey data and tax-benefit microsimulation models from the SOUTHMOD project, we provide a cross-country perspective on the redistributive...

On the presumption that poorer people tend to work less, it is often claimed that standard measures of inequality and poverty are overestimates. The paper points to a number of reasons to question this claim. It is shown that, while the labor supplies of American adults have a positive income...
