Identifying policies which can improve water sector management is critically important given the global burden of water-related disease. Each year, 1 in 10 child deathsroughly 800,000 in totalis the direct result of diarrhea. Can private-sector participation (PSP) in the urban piped water sector improve child health? The author uses child-level data from 39 African countries during 19862010 to show that introducing PSP decreases diarrhea among urban dwelling children under five years of age by 5.6 percentage points, or 35 percent of its mean prevalence. PSP also leads to greater reliance on piped water. To attribute causality, the author exploits time variation in the private water market share controlled by African countries former colonizers. A placebo analysis reveals that PSP does not affect symptoms of respiratory illness in the same children, nor does it affect a rural control group unaffected by PSP.
This study has been conducted in order to generate evidence of the visibility of exit from farm input subsidies in an African context. The study simulates the impact of alternative exit strategies from Malawis farm input subsidy program on maize markets. The simulation is conducted using a multiequation partial equilibrium model of the national maize market, which is sequentially linked via a price-linkage equation to local rural maize markets. The model accounts for market imperfections prevailing in the country that arise from government price interventions. Findings show that some alternative exit strategies have negative and sustained impacts on maize yields, production, and acreage al...
Though there is increasing evidence of the availability and potential of new agricultural technologies in Africa south of the Sahara, effective demand for them is still low. A recent refocus on increasing farmers use of modern technologies such as improved seed and chemical fertilizer has led to a resurgence of input subsidies for these products in many developing countries. One popular mechanism currently in use is input vouchers. Targeted input vouchers are intended to simultaneously improve the targeting of subsidies and develop demand in private markets. While there is growing evidence of the impact of targeted subsidies on private input demand, as far as we are aware no empirical stud...
This book showcases the potential of computational approaches for research questions at the heart of migration and integration research via a set of original, cutting-edge empirical studies by a diverse, international team of authors. Why do people emigrate? Do weather conditions and climate change affect decisions to migrate? How do migration networks evolve on a global scale? Can we predict refugee movements? How do host communities respond to the influx of refugees? Do right-wing populist parties get stronger where lots of refugees are located? Do terror attacks lead to more hostility towards immigrants? What mechanisms explain neighborhood ethnic segregation? The collection of studies in...
Nigeria has for decades placed enormous emphasis on diversifying its economy beyond oil and into sectors such as agribusiness and manufacturing. Lack of progress on the diversification agenda could be blamed on weak implementation and misalignment of public spending, but it also reflects more profound underlying issues. For example, declarations that any particular sector should drive diversification without offering clarity on specific investment priorities and expected outcomes will not persuade budget holders to allocate development resources. The lack of clarity also deprives policy makers and practitioners of the information, inspiration, and conviction to develop and execute sector pla...
Group lending has been widely adopted in the past thirty years by many microfinance institutions as a means to mitigate information asymmetries when delivering credit to the poor. This paper proposes an empirical method to address the potential omitted-variable problem resulting from unobserved group types when modeling the repayment behavior of group members. We estimate the model using a rich dataset from a group-lending program in India. The estimation results support our model specification and show the advantages of relying on a type-varying method when analyzing the probability of default of group members. In particular, our model helps to better understand the factors driving repayment behavior, which may differ across group types, and shows a higher predictive power than standard single-agent choice models.
This report answers the question: “What guidelines can be used to identify the types of agricultural investments that have the highest economic return, where “agriculture” is broadly defined to include primary production, handling, storage, transportation, distribution, processing, and retailing?” Using the literature and MCC’s ERR analyses, we explain how agricultural investments fit in a wider development context, identify information useful to MCC’s decision making that is not provided by the ERR analyses, and suggest IFPRI tools for exploratory and ex-ante evaluative analysis that MCC can use in their decision-making process.
Agriculture in African South of the Sahara (SSA) can be transformed if the right public support is provided at the initial stage, and it can sustain itself once the enabling environment is put in place. Successes are also specific to the location of projects. In Ghana, interesting insights are obtained from the successful Kpong Irrigation Project (KIP), contrasted with other major irrigation projects in the country. Through an exploratory review, we describe how a productive system evolved in KIP and how public support for critical aspects (accumulation of crop husbandry knowledge, selection and supply of profitable varieties, and mechanization of land preparation) might have created a productive environment that the private sector could enter and fill in the market for credit, processing, mechanization of harvesting, and other institutional voids that typically have constrained agricultural transformation in the rest of SSA. Slower progress in other projects also raises a number of questions. We conclude by summarizing those questions and some testable hypotheses for future research.
Addressing emerging global poverty, hunger, and malnutrition challenges requires prudent evidence-based policymaking at the country level. Capacity for generating evidence remains a major constraint in the policy process in developing countries. We surveyed 30 countries to measure the capacity of their individuals, organizations, and policy process system to undertake food and agricultural policy research. Our Food Policy Research Capacity Index, constructed using measures of human capacity (PhD full-time equivalent researchers per million rural residents), human capacity productivity (publications per PhD full-time equivalent researcher), and strength of institutions (the government effecti...
