Taxes and transfers can have significant impacts on poverty and inequality. All standard measures are by definition anonymous in the sense that we do not know the identity of winners and losers. That a given combination of taxes and transfers makes some of the poor poorer, however, may be...

Inequality in Mexico rose between 1989 and 1994 and declined between 1994 and 2010. We examine the role of market forces (demand and supply of labour by skill), institutional factors (minimum wages and unionization rate), and public policy (cash transfers) in explaining changes in inequality. We...

Inequality and poverty fell sharply in many Latin American countries during a decade in which voters in ten countries chose left-leaning leaders. Are these developments related? Using data for 18 Latin American countries, this paper presents econometric evidence that social democratic regimes in...

This paper tests the sensitivity of poverty indexes to the choice of adult equivalence scales, assumptions about the existence of economies of scale in consumption, methods for treating missing and zero incomes, and different adjustments to handle income misreporting. We also perform sensitivity...

Rising food prices cause considerable policy dilemmas for developing country governments. Letting domestic prices adjust to reflect the full change in international prices generates inflationary pressures and causes severe hardship for poor households lacking access to social safety nets....

The effect of taxes and benefits on the poor is usually measured using standard poverty and inequality indicators, stochastic dominance tests, and measures of progressivity and horizontal inequity. However, these measures can fail to capture an important aspect: that some of the poor are made...

This handbook presents a step-by-step guide to applying the incidence analysis used in the multi-country Commitment to Equity Project (CEQ). We define the pre- and post-net transfer income concepts, discuss the methodological assumptions used to construct them, explain how taxes, subsidies and...

World food commodities prices increased 130 percent from January 2002 to July 2008. Individual agricultural commodities show even more pronounced increases: corn, wheat, rice and soybeans rose by 190, 162, 318 and 246 percent, respectively. Since July, food commodities prices began to fall....

Current policy discussion focuses primarily on the power of fiscal policy to reduce inequality. Yet, comparable fiscal incidence analysis for 28 low and middle income countries reveals that, although fiscal systems are always equalizing, that is not always true for poverty. In Ethiopia,...

This evaluation of World Bank research between 1998 and 2005 was carried out by a panel consisting of Abhijit Banerjee (MIT), Angus Deaton (Princeton, chair), Nora Lustig (UNDP), and Kenneth Rogoff (Harvard.) The panel selected a large random sample of research projects, which were read and...
