It is sometimes argued that poorer people choose to work less, implying less welfare inequality than suggested by observed incomes. Social policies have also acknowledged that efforts differ, and that people respond to incentives. Prevailing measures of inequality (in outcomes or opportunities)...

The paper provides new measures of global poverty that take seriously the idea of relative-income comparisons but also acknowledge a deep identification problem when the latent norms defining poverty vary systematically across countries. Welfare-consistent measures are shown to be bounded below...

"In this paper we propose a new approach to international comparisons of real GDP measured from the output-side. The traditional Geary-Khamis system to measure real GDP from the expenditure-side is modified to include differences in the terms of trade between countries. It is shown that this...

Current global inequality measures assume that national-mean income does not matter to economic welfare at given household income, as measured in surveys. The paper questions that assumption on theoretical and empirical grounds and finds that prominent stylized facts about global inequality are...

Longstanding development issues are revisited in the light of our newly-constructed dataset of poverty measures for India spanning 60 years, including 20 years since reforms began in earnest in 1991. We find a downward trend in poverty measures since 1970, with an acceleration post-1991, despite...

The latest World Bank estimates of real GDP per capita for China are significantly lower than previous ones. We review possible sources of this puzzle and conclude that it reflects a combination of factors, including substitution bias in consumption, reliance on urban prices which we estimate...

In a rare example of an explicit national goal for income distribution besides reducing poverty, China's leadership has recently committed to expanding the middle-income share--moving to a less polarized "olive-shaped" distribution. Recognizing the potential trade-offs, the paper asks whether...

Low response rates among rich households are thought to be a serious problem in many applications using household surveys. The paper discusses the various ways the problem can be dealt with, and makes some recommendations for practice, including in developing countries. Under certain conditions,...

The path of income inequality in post-reform China has been widely interpreted as "China's Kuznets curve." We show that the Kuznets growth model of structural transformation in a dual economy, alongside population urbanization, has little explanatory power for our new series of inequality...
