Abstract: |
How unequal is the world today? Is global income inequality falling, as many economists claim, or is it rising, as one often hears?This paper reviews the arguments and evidence. A number of concerns about the underlying data are identified, with biases going in both directions. Conceptual issues further cloud the picture. The claim that global inequality has been falling since 1990 can be defended for a subset of the admissible parameter values, but only a subset.Global inequality is found to be rising if one or more of the following conditions holds: (i) one attaches a high ethical weight to the poorest; (ii) one has a strong ethical aversion to high-end inequality; (iii) one takes a nationalistic perspective, emphasizing relative deprivation within countries; or (iv) one sees inequality as absolute rather than relative.Popular debates on this topic would benefit from greater clarity on the concepts used, and greater awareness of data limitations. |

Abstract: |
This paper is the first to compare global trends in income and wealth inequality this century. It is based on large income and wealth microdata samples designed to be representative of all countries in the world.Measured by the Gini coefficient, inequality between countries accounts for about two-thirds of global income inequality, but noticeably less— around one half—of wealth inequality. Broadly similar results are found for different years and different inequality indices, bar the share of the top 1 per cent. Over time, changes in countries’ mean income and wealth, and population sizes, have reduced world inequality.Income inequality has changed little within countries, so the downward trend remains intact. However, within-country wealth inequality has risen, halting the downward shift in global wealth inequality and raising the share of the top 1 per cent after 2007. |

Abstract: |
The Great Recessions was essentially a ‘mancession’ in countries like Spain, the UK or the US, i.e. it hit men harder than women for they were disproportionately represented in heavily affected sectors. We investigate how the mancession, and more generally women’s relative opportunities on the labor market, translate into within-household redistribution. Precisely, we estimate the spouses’ resource shares in a collective model of consumption, using Spanish data over 2006-2011. We exploit the gender-oriented evolution of the economic environment to test two original distribution factors: first the regional-time variation in spouses’ relative unemployment risks, then the gender-differentiated shock in the construction sector (having a construction sector husband after the outburst of the crisis). Both approaches conclude that the resource share accruing to Spanish wives increased by around 7-9 percent on average, following the improvement of their relative labor market positions. Among childless couples, we document a 5-11 percent decline in individual consumption inequality following the crisis, which is essentially due to intrahousehold redistribution. |

Abstract: |
We evaluate the impact of a conditional cash transfer (CCT) program that we designed on family well-being among low-income families with young children. Although most CCTs have been implemented in low-income countries, our research is in the context of a high-income country, Italy, where the recent economic crises have worsened the conditions of families with children, especially among immigrants. Our objective is to evaluate the introduction of conditionality (attendance of courses) into a pre-existing unconditional cash transfer program. Using a randomized controlled trial, we find that CCT families search more actively for work, and they work more hours and more regularity than the cash transfer and control groups. CCT families also are able to save more money and eat healthier foods. The CCT intervention appears to be more effective than cash transfer alone in changing households’ behavior in several dimensions of well-being. Our findings add to the accumulating evidence on the impact of conditional cash transfers versus unconditional ones and to the literature concerning multidimensional incentive programs. |
