Inequality of opportunity and economic growth : a cross-country analysis

Income differences arise from many sources. While some kinds of inequality, caused by effort differences, might be associated with faster economic growth, other kinds, arising from unequal opportunities for investment, might be detrimental to economic progress. This study uses two new metadata sets, consisting of 118 household surveys and 134 Demographic and Health Surveys, to revisit the question of whether inequality is associated with economic growth and, in particular, to examine whether inequality of opportunity -- driven by circumstances at birth -- has a negative effect on subsequent growth. The results are suggestive but not robust: while overall income inequality is generally negatively associated with growth in the household survey sample, we find no evidence that this is due to the component associated with unequal opportunities. In the Demographic and Health Surveys sample, both overall wealth inequality and inequality of opportunity have a negative effect on growth in some of the preferred specifications, but the results are not robust to relatively minor changes. On balance, although the results are suggestive of a negative association between inequality and growth, the data do not permit robust conclusions as to whether inequality of opportunity is bad for growth.

Is inequality underestimated in Egypt ? evidence from house prices

Household income surveys often fail to capture top incomes which leads to an underestimation of income inequality. A popular solution is to combine the household survey with data from income tax records, which has been found to result in significant upward corrections of inequality estimates. Unfortunately, tax records are unavailable in many countries, including most of the developing world. In the absence of data from tax records, this study explores the feasibility of using data on house prices to estimate the top tail of the income distribution. In an application to Egypt, where estimates of inequality based on household surveys alone are low by international standards, the study finds strong evidence that inequality is indeed being underestimated by a considerable margin. The Gini index for urban Egypt is found to increase from 36 to 47 after correcting for the missing top tail.

The distribution of consumption expenditure in Sub-Saharan Africa : the inequality among all Africans

This paper uses a set of national household surveys to study the regional Sub-Saharan Africa distribution of consumption expenditure among individuals during 1993 to 2008. The analysis puts the disparities in living standards that exist among persons in Africa into context with the disparities that exist within and between African countries. Regional interpersonal inequality has increased (from a Gini index of 52 percent in 1993 to 56 percent in 2008), driven by increasing disparities in living standards across countries, while there has been no systematic increase in within-country inequality. For the African distribution as a whole, growth of consumption expenditure (from household surveys) has been low (around 1 percent per year). This growth has been uneven and as a result the richest 5 percent of Africans received around 40 percent of the total gains, while the bottom third stagnated.

Fair Progress?: Economic Mobility across Generations around the World

Fair Progress? Economic Mobility across Generations around the World looks at an issue that has gotten much attention in the developed world, but with, for the first time, new data and analysis covering most of the world, including developing economies. The analysis examines whether those born in poverty or in prosperity are destined to remain in the same economic circumstances into which they were born and looks back over a half a century at whether children’s lives are better or worse than their parents’ in different parts of the world. It suggests local, national, and global actions and policies that can help break the cycle of poverty, paving the way for the next generation to realize their potential and improve their lives.

The Incidence of Subsidies to Residential Public Services in Argentina: The Subsidy System in 2014 and Some Alternatives

More than a decade of energy and transport subsidies have weakened Argentina’s fiscal capacity. Following the 2001 crisis, public services tariffs were frozen in an attempt to offset the negative effects on households’ real purchasing power. However, these subsidies steadily increased over the years, particularly since 2006, becoming a significant fiscal burden. Though subsidies can be a tool to protect the poor, in Argentina they led to distortions and a large share have been absorbed by upper classes and non-residential consumers. This paper first analyzes the incidence of the 2014 system of residential federal subsidies to residential public services (defined as electricity, gas, water and transport) and then simulates the distributional impacts of alternative subsidy structures. Simulations on the electricity sector suggest that targeting consumption levels through a simple lifeline tariff is not sufficient to achieve a propoor incidence of subsidies. Instead, explicit targeting is necessary (though not sufficient) and needs to ensure comprehensive coverage of the poorest households. Similarly, on the transport sector show that the existing tariffs are not well-targeted, but that an expanded set of social programs could improve coverage of the poorest. Gas subsidy simulations showed that a social tariff would virtually eliminate the subsidy, suggesting that there is little overlap between the receipt of social programs and access to piped gas.
