Standard measures of poverty may reveal nothing about whether the poorest of the poor are being lifted-up or left-behind, yet this is a widespread concern among policy makers and citizens. The paper assesses whether public spending on social protection benefits the poorest and hence lifts the...

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...

Thirty years of distributional data are used to study the short-term impacts of popular macroeconomic indicators on real household incomes from the poorest to the richest Americans. The appropriate weights on unemployment versus inflation vary across the distribution. The unemployment rate...

Not much is obvious about how socioeconomic inequalities impact the spread of infectious diseases once one considers behavioral responses, correlations among multiple covariates and the likely non-linearities and dynamics involved. Social distancing responses to the threat of catching COVID-19...

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...

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)...

We study how pre-pandemic inequalities in America influenced social distancing over the course of the COVID-19 pandemic. Richer counties tended to see more protective mobility responses in the initial (pre-pharmaceutical) phase, but less protective responses later. Near linearity of this income...

Ethnic riots broke out in Malaysia in 1969, prompting a national effort at affirmative action favoring the poorer (majority) of "Bumiputera" (mainly Malays). Since then, Malaysia's official poverty measures indicate one of the fastest long-term rates of poverty reduction in the world, due to...
