In this paper, the world distribution of personal incomes (WDPI) is estimated using a global sample comprising country sample clones. A clone is a random sample that reproduces – with predetermined high probability and precision – an unknown survey sample using information that is 'encoded'...

How does welfare affect the prosperity of mothers and their children? We study this question using a Canadian welfare reform and by linking administrative welfare records to tax returns, nearly all medical spending, and children's educational attainment. Eighty percent of mothers in the complier...

Welfare caseloads in North America halved following reforms in the 1990s and 2000s. We study how this shift affected families by linking Canadian welfare records to tax returns, medical spending, educational attainment, and crime data. We find substantial and heterogeneous employment responses...

To assess the impact of tax-benefit policy changes on income distribution over time, we suggest a methodology based on counterfactual simulations. We start by decomposing changes in inequality/poverty indices into three contributions: reforms of the tax-benefit structure (rules, rates, etc.),...

By inverting Saez (2002)'s model of optimal income taxation, we characterize the redistributive preferences of the Irish government between 1987 and 2005. The (marginal) social welfare function revealed by this approach is consistently comparable over time and show great stability despite...

This paper reviews developments in income and health poverty in Ireland over the 2003-2011 period using data from the Survey of Income and Living Conditions (SILC). It also examines developments in the correlation between the two. Income poverty fell up to and including 2009, after which this...

When measuring health inequality using ordinal data, analysts typically must choose between indices specifically based upon ordinal data and more standard indices using ordinal data which has been transformed into cardinal data. This paper compares inequality rankings across a number of...
