Much of the data underlying global poverty and inequality estimates is not in the public domain, but can be accessed in small pieces using the World Bank's PovcalNet online tool. To overcome these limitations and reproduce this database in a format more useful to researchers, we ran...

While measured remittances by migrant workers have soared in recent years, macroeconomic studies have difficulty detecting their effect on economic growth. We review existing explanations for this puzzle and propose three new ones. First, we offer evidence that a large majority of the recent...

It is time to fundamentally reframe the research agenda on remittances, payments, and development. We describe many of the research questions that now dominate the literature and why they lead us to uninformative answers. We propose reasons why these questions dominate, the most important of...

Many countries in Africa suffer high rates of underemployment or low rates of productive employment; many also anticipate large numbers of people to enter the workforce in the near future. This paper asks the question: Are African firms creating fewer jobs than those located elsewhere? And, if...

Social capital can help reduce adverse shocks by facilitating access to transfers and remittances.This study examines how various measures of social capital are associated with disaster recovery after the 2008 Sichuan earthquake. We find that households having a larger Spring Festival network in...

In this paper we identify a group of people in Latin America and other developing countries that are not poor but not middle class either. We define them as the vulnerable “strugglers”, people living in households with daily income per capita between $4 and $10 (at constant 2005 PPP dollar)....

Theory and evidence have raised concerns that microcredit does more harm than good, particularly when offered at high interest rates. We use a clustered randomized trial, and household surveys of eligible borrowers and their businesses, to estimate impacts from an expansion of group lending at...

How big is China's aid to Africa? Does it complement or undermine the efforts of traditional donors? China releases little information, and outside estimates of the size and nature of Chinese aid vary widely. In an effort to overcome this problem, AidData, based at the College of William and...

Jenny Aker and Isaac Mbiti examine the growth of mobile phone technology over the past decade and consider its potential impacts upon quality of life in low-income countries, with a particular focus on sub-Saharan Africa. They first provide an overview of the patterns and determinants of mobile...

We use a public economics framework to consider how pharmaceuticals should be priced when at least some of the Ramp;D incentive comes from sales revenues. We employ familiar techniques of public finance to relax some of the restrictions implied in the standard use of Ramsey pricing. In the more...
