How can the impact of aid be estimated in the presence of fungibility? And how far does fungibility reduce its benefits? These questions are analyzed in a context where a donor wants to target its efforts on a specific sector and specific geographic areas. A traditional...

We consider public debt from a long-term historical perspective, showing how the purposes for which governments borrow have evolved over time. Periods when debt-to-GDP ratios rose explosively as a result of wars, depressions and financial crises also have a long history. Many of these episodes...

Health systems are not just about improving health: good ones also ensure that people are protected from the financial consequences of receiving medical care. Anecdotal evidence suggests health systems often perform badly in this respect, apparently with devastating consequences for households,...

This paper provides new estimates of the global gains from multilateral trade reform and their distribution among developing countries in the presence of trade preferences. Particular attention is given to agriculture, as farmers constitute the poorest households in developing countries but are...

Many policy makers are concerned about dependence on resource exports. This paper examines four changes that reduce this dependence: (i) accumulation of capital and skills; (ii) changes in protection policy, particularly reductions in the burden of protection on exporters; (iii) differential...
