When Does One Dime = 100 Million People?

Ending extreme poverty is likely to be one of the UN Sustainable Development Goals for 2030. So it is a good idea to figure out what that entails. And it turns out that it’s become more complex in the last year or so. That’s because new price data, 2011 Purchasing Power Parity (PPP) estimates, were released in 2014 and the World Bank’s global poverty database, PovcalNet, also had a substantial update.

SDG One: First Fix the Goalposts

This is the latest in a series of CGD blogs suggesting improvements to the SDG targets.

The first target of the first goal of the Sustainable Development Goals is to “eradicate extreme poverty for all people everywhere” by 2030.  The second target is to “reduce at least by half the proportion of…. [people] living in poverty…..according to national definitions.”  

A Better Measure of Shared Prosperity

One of the World Bank’s two goals for developing countries is to “share prosperity,” which it measures by the growth rate in mean consumption (or income) for the poorest 40 percent of the population. That metric has the appeal of simplicity, but it tells us nothing at all about how rising prosperity — or economic contraction — is being shared among the poorest 40 percent.

National Vices, Global Virtue: Is the World Becoming More Equal?

You may find the answer surprising, but the most recent data show that the world as a whole is becoming more equal, driven by fast growth rates of China and India and slower growth rates in rich countries. A decrease in the US mean income from 2008 to 2011, for instance, makes global convergence of people’s incomes a lot easier to achieve. 

Another Good Reason to Dislike Low-Bar Global Poverty Lines

Angus Deaton said he didn’t mind poverty analysis as long as the poverty line is infinity.  Stevenson and Wolfers (2013) assemble the array of survey based measures of subjective well- being (SWB), such as “life satisfaction” or “happiness” and search for income satiation.
