Scientific evidence indicates that global warming could well lead to a sea-level rise of 1 meter or more in the 21st century. This paper seeks to quantify how a 1-meter sea-level rise that would affect coastal wetlands in 76 developing countries and territories, taking into account how much of...

Against what standards should we judge the developing world's overall performance against poverty going forward? The paper proposes two measures, each with both "optimistic" and "ambitious" targets for 2022, 10 years from the time of writing. The first measure is absolute consumption poverty, as...

This paper provides an overview of the history of development research at the World Bank and points to new future directions in both what we research and how we research. Six main messages emerge. First, research and data have long been essential elements of the Bank's country programs and its...

Global climate models predict a rise in extreme weather in the next century. To better understand future interactions among adaptation costs, socioeconomic development, and climate change in developing countries, observed losses of life from floods and droughts during 1960-2003 are modeled using...

We are not seeing faster progress against poverty amongst the poorest developing countries. Yet this is implied by widely accepted "stylized facts" about the development process. The paper tries to explain what is missing from those stylized facts. Consistently with models of economic growth...

Global climate models predict a rise in extreme weather in the next century. To better understand future interactions among adaptation costs, socioeconomic development, and climate change in developing countries, observed losses of life from floods and droughts during 1960-2003 are modeled using...

The "developing world's middle class" is defined here as those who are not poor when judged by the median poverty line of developing countries, but are still poor by US standards. The "Western middle class" is defined as those who are not poor by US standards. Although barely 80 million people...

Prevailing measures of relative poverty put an implausibly high weight on relative deprivation, such that measured poverty does not fall when all incomes grow at the same rate. This stems from the (implicit) assumption in past measures that very poor people incur a negligible cost of social...
