    Content: This study analyzes the impact of large-scale fee elimination for secondary school girls in The Gambia on the quantity, composition, and achievement of students. The gradual rollout of the program across geographic regions provides identifying variation in the policy. The program increased the number of girls taking the high school exit exam by 55 percent. The share of older test takers increased in poorer districts, expanding access for students who began school late, repeated grades, or whose studies had been interrupted. Despite these changes in the quantity and composition of students, there are robustly positive point estimates of the program on test scores, with suggestive evidence of gains for several subgroups of both girls and boys. Absence of learning declines is notable in a setting where expanded access could strain limited resources and reduce school quality. The findings suggest that financial constraints remain serious barriers to post-primary education, and that efforts to expand access to secondary education need not come at the expense of learning in low-income countries like The Gambia.

    Content: Education systems in developing countries are often centrally managed in a top-down structure. In environments where schools have different needs and where localized information plays an important role, empowerment of the local community may be attractive, but low levels of human capital at the local level may offset gains from local information. This paper reports the results of a four-year, large-scale experiment that provided a grant and comprehensive school management training to principals, teachers, and community representatives in a set of schools. To separate the effect of the training from the grant, a second set of schools received the grant only with no training. A third set of schools served as a control group and received neither intervention. Each of 273 Gambian primary schools were randomized to one of the three groups. The program was implemented through the government education system. Three to four years into the program, the full intervention led to a 21 percent reduction in student absenteeism and a 23 percent reduction in teacher absenteeism, but produced no impact on student test scores. The effect of the full program on learning outcomes is strongly mediated by baseline local capacity, as measured by adult literacy. This result suggests that, in villages with high literacy, the program may yield gains on students' learning outcomes. Receiving the grant alone had no impact on either test scores or student participation.

    Content: Access to reliable electricity is a prerequisite for the economic transformation of African economies, especially in a digital age. Yet the electricity access rate in Sub-Saharan African countries is often substantially low, households and businesses with access often face unreliable service, and the cost of the service is often among the highest in the world. This situation imposes substantial constraints on economic activities, provision of public services, adoption of new technologies, and quality of life.Much of the focus on how best to provide reliable, affordable, and sustainable electricity service to all has been on mitigating supply-side constraints. However, demand-side constraints may be as important, if not more important. On the supply side, inadequate investments in maintenance result in high technical losses; most state-owned utilities operate at a loss; and power trade, which could significantly lower the cost of electricity, is underdeveloped. On the demand side, the uptake and willingness to pay are often low in many communities, and the consumption levels of those who are connected are limited. Increased uptake and use will encourage investment to improve service reliability and close the access gap. This report shows that the fundamental problem is poverty and lack of economic opportunities rather than power. The solution lies in understanding that the overarching reasons for the unrealized potential involve tightly intertwined technical, financial, political, and geographic factors. The ultimate goal is to enable households and business to gain access, to afford to use, and utilities to recover their cost and make profits. The report makes the case that policy makers need to adopt a more comprehensive and long-term approach to electrification in the region-one centered on the productive use of electricity at affordable rates. Such an approach includes increased public and private investment in infrastructure, expanded access to credit for new businesses, improved access to markets, and additional skills development to translate the potential of expanded and reliable electricity access into substantial economic impact. Enhancing the economic capabilities of communities is the best way to achieve faster and more sustainable development progress while addressing the broad challenges of affordability, low consumption, and financial viability of utilities, as well as ensuring equitable provision between urban and rural areas.

    Content: This paper studies the impact of a computer-assisted learning program on learning outcomes among high school students in The Gambia. The program uses innovative technologies and teaching approach to facilitate the teaching of mathematics and science. Since the pilot schools were not randomly chosen, the study first used administrative and survey data, including a written test, to build a credible counterfactual of comparable groups of control students. It used these data to conduct a pre-analysis plan prior to students taking the high-stakes certification exam. The study later used the certification exam data on the same students to replicate the results. The findings show that the program led to a 0.59 standard deviation gains in mathematics scores and an increase of 15 percentage points (a threefold increase) in the share of students who obtained credit in mathematics and English, a criterion for college admission in The Gambia. The impact is concentrated among high-achieving students at the baseline, irrespective of their gender or socioeconomic background.

    Content: This paper provides evidence on how the provision of social infrastructure, such as reliable electricity, can be leveraged to increase taxation in developing countries, particularly in Sub-Saharan Africa. First, using comprehensive data from the latest round of the Afrobarometer survey, the paper uses the instrumental variable approach to estimate the effect of access to and reliability of electricity on the tax compliance attitudes of citizens in 36 countries in Sub-Saharan Africa. The evidence shows a significant positive effect of electrification on tax compliance attitudes, with potentially strong externalities. The analysis also finds that the reliability of supply is crucial in explaining the impact of electricity access on attitudes toward taxes. Second, the paper provides suggestive evidence on national identity as one channel driving this impact. Access to social amenities such as electricity induces a sense of national identity among citizens, thereby incentivizing them to contribute, through taxes, toward the functioning of the state. Third, using data from the most recent World Bank Enterprise Surveys and under conservative assumptions, the paper estimates that countries in the region could in total generate additional tax revenues of more than USD 9.5 billion (4.3 percent of total tax revenue) per year solely by resolving issues related to electricity shortages. Put together, the paper concludes that the financial returns associated with public investments toward improving access to and reliability of electricity are substantial and could be harnessed to augment the financing gap in the sector

    Content: This study develops and structurally estimates a model of household and electric utility behavior to describe how the low access rates and high connection charges that are common in the Sub-Saharan Africa region arise from regulated electricity tariffs being set too low. As a result, the utilities lose money on each connected customer and low electricity consumption by households makes it difficult to recover the cost of providing a connection. For each possible choice of the regulated tariff, the optimal upfront connection charge is computed that will maximize profits for the utility in its service territory. Higher tariffs are associated with lower optimal connection charges and higher electrification rates. Nonetheless, due to households' low willingness to pay for electricity services, the equilibrium electrification rates in the model are much lower than 100 percent. Future advances in electrification will require higher incomes, increased coverage of the distribution network, and lower connection costs

    Content: Early childhood experiences lay the foundation for outcomes later in life. Policy makers in developing countries face a dual challenge of promoting access to and quality of early childhood development services, but evidence on how to manage this trade-off is scarce. This paper studies two experiments of early childhood development programs in The Gambia: one increasing access to services, and another improving service quality. In the first experiment, new community-based early childhood development centers were introduced to randomly chosen villages that had no preexisting, structured early childhood development services. In the second experiment, a randomly assigned subset of existing early childhood development centers received intensive provider training. The analysis finds no evidence that either intervention improved average levels of child development. Exploratory analysis suggests that the first experiment, which increased access to relatively low-quality early childhood development services, led to declines in child development among children from less disadvantaged households. The evidence supports that these households may have been steered away from better quality early childhood settings in their homes. Comparisons of observationally similar children across experiments reveal that existing early childhood development centers increased language skills by 0.4 standard deviation relative to the community-based alternative, reflecting differences in program quality
