This paper surveys evidence from recent randomized evaluations in developing countries on the impact of price on access to health and education. The debate on user fees has been contentious, but until recently much of the evidence was anecdotal. Randomized evaluations across a variety of...

Climate negotiators in Cancún reached agreement that long-term climate finance will include a commitment by developed countries to mobilize US $100 billion per year to help developing countries combat climate change. However, that level of investment will require substantial capital from...

During the 1990s, the World Bank and several donor partners provided a “surge” in external aid to support Pakistan's social sectors. Despite the millions of donor dollars spent, the program failed. Poverty was higher in Pakistan in 2004 than it was a decade earlier when the antipoverty...

Existing studies from the United States, Latin America, and Asia provide scant evidence that private schools dramatically improve academic performance relative to public schools. Using data from Kenya — a poor country with weak public institutions — we find a large effect of private...

The combination of relatively high American barriers to trade in textiles and apparel and the importance of the sector to the Pakistani economy make increased market access a potentially powerful tool of U.S. policy. Unfortunately, recent proposals to extend duty-free market access for Pakistani...

International Development Association (IDA) donors and others operating a country performance-based allocation system face two difficult problems: how to strengthen incentives to produce and document development results and how to increase flexibility for fragile states. Fragile states have the...

This paper examines the potential benefits and costs of providing duty-free, quota-free market access to the least developed countries (LDCs), and the effects of extending eligibility to other small and poor countries. Using the MIRAGE computable general equilibrium model, it assesses the impact...

What have the MDGs achieved? And what might their achievements mean for any second generation of MDGs or MDGs 2.0? We argue that the MDGs may have played a role in increasing aid and that development policies beyond aid quantity have seen some limited improvement in rich countries (the evidence...

After a decade of rapid growth in average incomes, many countries have reached middle-income status. At the same time, however, poverty has not fallen so dramatically; as a result, most of the world's poor now live in middle-income countries (MICs). In fact, up to a billion poor people — or a...

Development finance is at a turning point. There is talk about a “triple revolution of goals, actors and tools.” As much of Asia grows its way out of poverty, aid will increasingly be focused on Africa and on countries plagued by instability, or with governments unable to meet the basic...
