Large numbers of doctors, engineers, and other skilled workers from developing counties choose to move to other countries. Do their choices threaten development? The answer appears so obvious that their movement is most commonly known by the pejorative term “brain drain”. This paper...

This paper compares the wages of workers inside the United States to the wages of observably identical workers outside the United States-controlling for country of birth, country of education, years of education, work experience, sex, and rural-urban residence. This is made possible by new and...

The US government’s proposed $5 billion Millennium Challenge Account (MCA) could provide upwards of $250-$300m or more per year per country in new development assistance to a small number of poor countries judged to have relatively “good” policies and institutions. Could this assistance be...

When is the rigorous impact evaluation of development projects a luxury, and when a necessity? The authors study one high-profile case: the Millennium Villages Project (MVP), an experimental and intensive package intervention to spark sustained local economic development in rural Africa. They...
