The Impacts of Climate Change on Regional Water Resources and Agriculture in Africa
This paper summarizes the methods and findings of the hydrological assessment component of the project studying likely impacts of climate change on water resources and agriculture in Africa. The first phase of the study used a version of a conceptual rainfall-runoff model called WatBal (Water Balance) applied to gridded data to simulate changes in soil moisture and runoff across the whole continent of Africa rather than to any particular catchment or water resource system. The model inputs were the climate variables of the 1961-90 climatology and physiological parameters (such as soil properties and land use) derived from global datasets for each of the 0.5 degree latitude/longitude cells ac...
Improving Effective Coverage in Health
In many low- and middle-income countries, health coverage has improved dramatically in the past two decades, but health outcomes have not. As such, effective coverage—a measure of service delivery that meets a minimum standard of quality—remains unacceptably low. Improving Effective Coverage in Health examines one specific policy approach to improving effective coverage: financial incentives in the form of performance-based financing (PBF), a package reform that typically includes performance pay to frontline health workers as well as facility autonomy, transparency, and community engagement. This Policy Research Report draws on a rich set of rigorous studies and new analysis. When compa...
Hidden Impact?
By the widely used difference-in-difference method, the Southwest China Poverty Reduction Project had little impact on the proportion of people in beneficiary villages consuming less than $1 a day-despite a public outlay of $400 million. Is that right, or is the true impact being hidden somehow? The authors find that impact estimates are quite sensitive to the choice of outcome indicator, the poverty line, and the matching method. There are larger poverty impacts at lower poverty lines. And there are much larger impacts on incomes than consumptions. Uncertainty about the impact probably made it hard for participants to infer the gain in permanent income, so they saved a high proportion of the short-term gain.
The "Glass of Milk" Subsidy Program and Malnutrition in Peru
The authors evaluate the Vaso de Leche (VL) feeding program in Peru. They pose the question that if a community-based multistage targeting scheme such as that of the VL program is progressive, is it possible that the program can achieve its nutritional objectives? The authors address this by linking VL public expenditure data with household survey data to assess the targeting, and then to model the determinants of nutritional outcomes of children to see if VL program interventions have an impact on nutrition. They confirm that the VL program is well targeted to poor households and to those with low nutritional status. While the bulk of the coverage of the poor is attributed to targeting of p...
A Cross-country Analysis of Public Debt Management Strategies
This paper analyzes results of a survey on debt management strategies conducted by the Banking and Debt Management Department of the World Bank. The analysis focuses on (1) whether a public debt management strategy exists in a given country, (2) whether it is made public, and (3) in which form it is imparted. The paper analyzes the distribution of the latter characteristics over different regions, income groups, and levels of indebtedness using graphical analysis. Using regression analysis, it investigates the extent to which basic economic factors can explain the characteristics of public debt management strategies across countries.
Innovation Shortfalls
There is a common perception that low productivity or low growth is due to what can be called an "innovation shortfall," usually identified as a low rate of investment in research and development (R&D) when compared with some high innovation countries. The usual reaction to this perceived problem is to call for increases in R&D investment rates, usually specifying a target that can be as high as 3 percent of GDP. The problem with this analysis is that it fails to see that a low R&D investment rate may be appropriate given the economy's pattern of specialization, or may be just one manifestation of more general problems that impede accumulation of all kinds of capital. How can we know when a ...
Short-term and long-term effects of cash for work: Evidence from a randomized controlled trial in Tunisia
While a growing literature analyzes the economic effects of cash for work programs in developing countries, there remains little evidence about the longer-term effects of these interventions. This paper presents findings from a randomized controlled trial evaluating a three month intervention providing public works employment in rural Tunisia. The evaluation design incorporates two dimensions of randomization — community-level randomization to treatment and control, and individual-level randomization among eligible individuals — and a sample of 2,718 individuals was tracked over five years. The findings suggest that cash for work leads to significant increases in labor market engagement, assets, consumption, financial inclusion, civic engagement, psychological well being, and women’s empowerment one-year post-treatment; however, these effects have largely attenuated to zero five years post-treatment, with the exception of a positive effect on assets. There is also evidence of positive spillover effects within treatment communities, but these effects similarly attenuate over time
