A revised version may be available directly from the author. The higher value of the line in US dollars reflects the fact that the new PPPs yield a relatively lower purchasing power of that currency vis-à-vis those of most poor countries. Because the line was designed to preserve real purchasing power in poor countries, the revisions lead to relatively small changes in global poverty incidence: from 14.5 percent in the old method to 14.1 percent in the new method for 2011. In 2012, the new reference year for the global count, we find 12.7 percent of the world's population, or 897 million people, are living in extreme poverty. There are changes in the regional composition of poverty, but they are also relatively small. This paper documents the detailed methodological decisions taken in the process of updating both the poverty line and the consumption and income distributions at the country level, including issues of inter-temporal and spatial price adjustments. It also describes various caveats, limitations, perils and pitfalls of the approach taken.
Cash transfer programmes are a popular social protection tool in developing countries that aim, among other things, to improve education outcomes in developing countries. The debate over whether these programmes should include conditions has been at the forefront of recent policy discussions. This systematic review aims to complement the existing evidence on the effectiveness of these programmes in improving schooling outcomes and help inform the debate surrounding the design of cash transfer programmes. Using data from 75 reports that cover 35 different studies, the authors find that both conditional cash transfers (CCTs) and unconditional cash transfers (UCTs) improve the odds of being enrolled in and attending school compared to no cash transfer programme. The effect sizes for enrolment and attendance are always larger for CCTs compared to UCTs, but the difference is not statistically significant. When programmes are categorised as having no schooling conditions, having some conditions with minimal monitoring and enforcement and having explicit conditions that are monitored and enforced, a much clearer pattern emerges whereby programmes that are explicitly conditional, monitor compliance and penalise non-compliance have substantively larger effects (60% improvement in odds of enrolment). Unlike enrolment and attendance, the effectiveness of cash transfer programmes on improving test scores is small at best. More research is needed that examines longer-term outcomes such as test scores and, more generally, evaluating the impacts of UCTs.
