Abstract:
Expanding credit access is a key ingredient of development strategies worldwide. Microfinance practitioners, policymakers, and donors have ambitious goals for expanding access, and seek efficient methods for implementing and evaluating expansion. There is less consensus on the role of consumer credit in expansion initiatives. Some microfinance institutions are moving beyond entrepreneurial credit and offering consumer loans. But many practitioners and policymakers are skeptical about “unproductive” lending. These concerns are fueled by academic work highlighting behavioral biases that may induce consumers to overborrow. We estimate the impacts of a consumer credit supply expansion using a field experiment and follow-up data collection. A South African lender relaxed its risk assessment criteria by encouraging its loan officers to approve randomly selected marginal rejected applications. We estimate the resulting impacts using new survey data on borrower behavior and well-being, and administrative data on loan repayment. We find that the marginal loans increased credit access and produced measurable benefits in the form of increased employment, reduced hunger, and reduced poverty. The marginal loans also appear to have been profitable for the lender. The results must be interpreted with caution but suggest that consumer credit expansions can be welfare-improving.

82. AIDS Treatment and Intrahousehold Resource Allocations: Children's Nutrition and Schooling in Kenya

Abstract:
The provision of life-saving antiretroviral (ARV) treatment has emerged as a key component of the global response to HIV/AIDS, but very little is known about the impact of this intervention on the welfare of children in the households of treated persons. We estimate the impact of ARV treatment on children's schooling and nutrition outcomes using longitudinal household survey data collected in collaboration with a treatment program in western Kenya. We find that children's weekly hours of school attendance increase by over 20 percent within six months after treatment is initiated for the adult household member. For boys in treatment households, these increases closely follow their reduced market labor supply. Similarly, young children's short-term nutritional status—as measured by their weight-for-height Z-score—also improves dramatically. We also present evidence that the impact of treatment is considerably larger when compared to the counterfactual scenario of no ARV treatment. The results illustrate how intrahousehold allocations of time and resources are altered in response to significant health improvements. Since the improvements in children's schooling and nutrition at these critical early ages will affect their socio-economic outcomes and wellbeing in adulthood, the widespread provision of ARV treatment is likely to generate significant long-run welfare benefits.

83. Why Are There So Few Black-Owned Firms in Africa? Preliminary Results from Enterprise Survey Data

Abstract:
Much of the growth in Sub-Saharan Africa in the past decade has come from extractive industries, rather than from private, entrepreneurial activity. Furthermore, non-extractive activity in the private sector is often dominated by firms owned by ethnic minorities. This paper analyzes the characteristics of the formal private sector in five countries in sub-Saharan Africa, with a particular emphasis on Black African-owned (indigenous) firms. We find that indigenous firms start smaller and grow more slowly; however their rate of growth is positively influenced by whether the owner-entrepreneur has a university degree. We do not find overwhelming evidence that credit is the binding constraint but we do find that indigenous firms get less access to trade credit than firms owned by minority entrepreneurs. Finally, we discuss policy solutions that might enable a larger number of indigenous entrepreneurs to enter and survive in a vibrant, multi-ethnic private sector.

84. New data on African health professionals abroad

Abstract:
The migration of doctors and nurses from Africa to developed countries has raised fears of an African medical brain drain. But empirical research on the causes and effects of the phenomenon has been hampered by a lack of systematic data on the extent of African health workers' international movements. We use destination-country census data to estimate the number of African-born doctors and professional nurses working abroad in a developed country circa 2000, and compare this to the stocks of these workers in each country of origin. Approximately 65,000 African-born physicians and 70,000 African-born professional nurses were working overseas in a developed country in the year 2000. This represents about one fifth of African-born physicians in the world, and about one tenth of African-born professional nurses. The fraction of health professionals abroad varies enormously across African countries, from 1% to over 70% according to the occupation and country. These numbers are the first standardized, systematic, occupation-specific measure of skilled professionals working in developed countries and born in a large number of developing countries.

85. Will Debt Relief Make a Difference? Impact and Expectations of the Multilateral Debt Relief Initiative

Abstract:
The Multilateral Debt Relief Initiative (MDRI) is the latest phase of debt reduction for poor countries from the World Bank, the IMF, and the African Development Bank. The MDRI, which will come close to full debt reduction for at least 19 (and perhaps as many as 40) qualifying countries, is being presented as a momentous leap forward in the battle against global poverty. However, the analysis in this paper suggests that the actual gains may be more modest and elusive. This is not because, as some anti-debt campaigners fear, that the initiative is a mere accounting trick. Rather, the limited short-term financial impact of the MDRI on affected countries is because the debt service obligations being relived were themselves relatively insignificant. For example, in 2004 the average African country in the program paid $19 million in debt service to the World Bank, but received 10 times that amount in new Bank credit and more than 50 times as much in total aid. Just as importantly, finances are rarely the binding constraint on poverty and other development outcomes. This is not to say that the MDRI is futile. Indeed the impact could be considerable over the long-term, especially on the ability of creditors to be more selective in the future. But most of the impact of the MDRI will be long-term and difficult to measure. As such, expectations of the effect on indebted countries and development indicators should be kept modest and time horizons long.

86. Back to the Future for African Infrastructure? Why State-Ownership Is No More Promising the Second Time Around

Abstract:
Too many African state-owned enterprises (SOEs), particularly those in infrastructure sectors, have a long history of poor performance. African governments and donors labored through the 1970s and 1980s to improve SOE performance through “commercialization”——i.e., methods short of ownership change. These generally failed, giving rise, in the 1990s, to much more heavy reliance on private sector participation and ownership. This approach produced some successes, but Africa's private participation in infrastructure (PPI) initiatives have been comparatively few and weak. A number of those that have been launched have run into problems, to the point where both investor and African government interest in the approach has waned in the last few years. The reform is not popular——surveys of public opinion in 15 African countries reveal that only a third of respondents prefer private to state-owned firms. Nonetheless, African states (and their supporters) should not jettison the PPI approach. Rather, they should acknowledge its limitations, and recognize the large scope and moderate pace of the preparatory measures required both to improve their investment climates and to make PPI work effectively.

87. An Aid-Institutions Paradox? A Review Essay on Aid Dependency and State Building in Sub-Saharan Africa

Abstract:
A number of proposals today support a substantial increase in foreign aid levels to sub-Saharan Africa even though this region already receives a historically unprecedented volume of aid. This essay reviews the evidence regarding the potentially negative effects of aid dependence on state institutions, a topic which has received relatively little attention. We note several pathways through which political institutions might be adversely affected and devote particular attention to fiscal and state revenue issues. In addition to reviewing the economic literature on the aid-revenue relationship, this essay brings in the long-standing political science literature on state-building to consider the potential impact of aid dependence on the relationship between state and citizen. We conclude that states which can raise a substantial proportion of their revenues from the international community are less accountable to their citizens and under less pressure to maintain popular legitimacy. They are therefore less likely to have the incentives to cultivate and invest in effective public institutions. As a result, substantial increases in aid inflows over a sustained period could have a harmful effect on institutional development in sub-Saharan Africa.
