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...

All interested parties seem to agree that it is important to be able to monitor public sector performance at the sectoral level, but most current work based on multi-country databases does not lend itself to country-specific conclusions. This is due to a large extent to major data limitations...

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...

This paper presents an empirical analysis of speculative attacks on pegged exchange rates in 22 countries between 1967 and 1992. We define speculative attacks or crises as large movements in exchange rates, interest rates, and international reserves. We develop stylized facts concerning the...

The authors explore the relation between the establishment of a regulatory agency and the performance of the electricity sector. The authors exploit a unique dataset comprising firm-level information on a representative sample of 220 electric utilities from 51 development and transition...

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 shows empirically that "privatization" in the energy, telecommunications, and water sectors, and the introduction of independent regulators in those sectors, have not always had the expected effects on access, affordability, or quality of services. It also shows that corruption leads...

Thirty years ago, in 1974, Chile launched the first large-scale privatization in a developing country. About 15 years later, Argentina provided a new model of global infrastructure management. Since then a variety of public-private partnerships in infrastructure have been adopted throughout the...

The authors review about 80 studies on electricity and gas, water and sanitation, and rail and ports (with a footnote on telecommunications) in developing countries. The main policy lesson is that there is a difference in the relevance of ownership for efficiency between utilities and transport...

The authors examine the effects of the introduction of Vietnam's health insurance (VHI) program on health outcomes, health care utilization, and non-medical household consumption. The use of panel data collected before and after the insurance program's introduction allows them to eliminate any...
