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...

The paper critically assesses prevailing measures of global poverty. A welfarist interpretation of global poverty lines is augmented by the idea of normative functionings, the cost of which varies across countries. In this light, current absolute measures are seen to ignore important social...

Relative deprivation, shame and social exclusion can matter to the welfare of people everywhere. The authors argue that such social effects on welfare call for a reconsideration of how we assess global poverty, but they do not support standard measures of relative poverty. The paper argues...

While much progress has been made over the last 25 years in measuring global poverty, there are a number of challenges ahead. The paper discusses three sets of problems: (i) how to allow for social effects on welfare, recognizing the identification issues involved; (ii) the need to monitor...

The traditional approach to poverty measurement puts no explicit weight on success at increasing the typical level of living of the poorest—raising the consumption floor. To address this deficiency, the paper defines and measures the expected value of the floor, allowing for transient effects...
