I’m very grateful  to Olivier de Schutter, UN special rapporteur on extreme poverty and human rights, for his discussion of Zack Gehan and my paper on future growth forecasts and poverty in 2050. There is much to agree with in his analysis, but I’d disagree with his statement “our focus should be on...

In the next few weeks, the OECD will release its estimate of ODA—Official Development Assistance—provided by member countries, and will no doubt claim yet another record high.

We found that policy lending projects are significantly faster to design, while projects that under...

The World Bank’s Evolution Roadmap suggests the institution could provide more grants and subsidies to activities that support the provision of global public goods (GPGs), particularly in richer developing countries. Provision of those public goods is surely a priority: avoiding future pandemics and...

I'm not a huge fan of arbitrary lines through country income levels to create income thresholds.

The process suggests a considerable degree of uncertainty about how the world will look in three de...

Neither goal can be accomplished unless the extreme poverty line is (finally) fixed rather than constant...
