It will be politically difficult to liberalize international migration without protecting host-country workers. The paper explores the scope for efficiently managing migration using a competitive market for work permits. Host-county workers would have the option of renting out their citizenship...

The paper formalizes and tests the hypothesis that greater exposure to big shocks induces stronger societal responses for adaptation and protection from future big shocks. We find support for this hypothesis in various strands of the literature and in new empirical tests using cross-country data...

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...

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...

Evidence on the implementation of India's National Rural Employment Guarantee Act suggests that the available work is often rationed by local leaders in poor areas, and that this is an important factor limiting the scheme's impact on poverty. The paper offers explanations for this empirical...

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...

The Purchasing Power Parity (PPP) rates from the 2011 round of the International Comparison Program (ICP) imply some dramatic revisions to price levels and real incomes across the world. The paper tries to understand these changes. Domestic inflation rates account for a share of the PPP changes,...

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...

The widely held view that China has greatly reduced income poverty over the last 40 years does not accord with all the evidence. The paper tries to reconcile the conflicting findings. The fact that strongly-relative measures show rising poverty is easily understood, since such measures depend...

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)...
