Economic Transformation in Africa from the Bottom Up: New Evidence from Tanzania
(Published by Oxford University Press on behalf of the World Bank, 2020-02)Tanzania's rapid labor productivity growth has been accompanied by a proliferation of small, largely informal firms. Using Tanzania's first nationally representative survey of micro, small, and medium-sized enterprises (MSMEs)—this paper explores the nature of these businesses. It finds that these firms are located in both rural and urban areas and that they operate primarily in trade services and manufacturing. Roughly half of all business owners say they would not leave their job for a full-time salaried position. Fifteen percent of these small businesses contribute significantly to economy-wide labor productivity. The most important policy implication of the evidence presented in this paper is that if the goal is to grow MSMEs with the potential to contribute to productive employment, policies must be targeted at the most promising firms. -

Cash Transfers and Health: Evidence from Tanzania
(Published by Oxford University Press on behalf of the World Bank, 2019-06)How do cash transfers conditioned on health clinic visits and school attendance impact health-related outcomes? Examining the 2010 randomized introduction of a program in Tanzania, this paper finds nuanced impacts. An initial surge in clinic visits after 1.5 years—due to more visits by those already complying with program health conditions and by non-compliers—disappeared after 2.5 years, largely due to compliers reducing above-minimal visits. The study finds significant increases in take-up of health insurance and the likelihood of seeking treatment when ill. Health improvements were concentrated among children ages 0–5 years rather than the elderly, and took time to materialize; the study finds no improvements after 1.5 years, but 0.76 fewer sick days per month after 2.5 years, suggesting the importance of looking beyond short-term impacts. Reductions in sick days were largest in villages with more baseline health workers per capita, consistent with improvements being sensitive to capacity constraints. These results are robust to adjustments for multiple hypothesis testing. -

What Drives Local Food Prices? Evidence from the Tanzanian Maize Market
(Published by Oxford University Press on behalf of the World Bank, 2019-02)We examine the drivers of monthly changes in maize prices across 18 Tanzanian markets. Local prices respond three to four times faster to the main regional market (Nairobi) than to the international benchmark (US Gulf). More importantly, shocks from Nairobi account for only one third of the explained variation in domestic prices; the remaining two-thirds is accounted for by domestic influences (including harvest cycles, weather shocks, and trade policies). Further, we show that remoteness and the local agroecology systematically influence the behavior of food prices. -

Progressive Pathway to Universal Health Coverage in Tanzania: A Call for Preferential Resource Allocation Targeting the Poor
(Taylor and Francis, 2018-10-31)Universal health coverage (UHC) can be a vehicle for improving equity, health outcomes, and financial well-being. After publication of the World Health Organization’s report in 2010, many countries declared their goal of achieving UHC. A key lesson from research evidence and country experience in implementation of pro-poor UHC is that public budget plays a crucial role in financing the poor. It has long been recognized that if a country wants to reduce the gap between the poor and non-poor, deprived groups should receive preferential allocation of health care resources to achieve more rapid improvements in their health. Based on a technical analysis of public funds allocation mechanisms in Tanzania, we argue that these mechanisms should prioritize the poor more explicitly and give them preferential treatment to close the gap with the non-poor in service utilization and health outcomes. -

Can Agricultural Interventions Improve Child Nutrition? Evidence from Tanzania
(Published by Oxford University Press on behalf of the World Bank, 2017-10-01)Severely reduced height-for-age due to undernutrition is widespread in young African children, with serious implications for their health and later economic productivity. It is primarily caused by growth faltering due to hunger spells in critical periods of early child development. We assess the impact on early childhood nutrition, measured as height-for-age, of an agricultural intervention that improved food security among smallholder farmers by providing them with a “basket” of new technology options. We find that height-for-age measures among children from participating households increased by about 0.9 standard deviations and the incidence of stunting among them decreased by about 18 percentage points. -

Producing Home Grown Solutions : Think Tanks and Knowledge Networks in International Development
( 2011-09)Mainstream international development discourse has long heralded the importance of home grown solutions and national ownership of development policies. Ownership has been seen as the missing link between the significant development aid inflows from the North and poverty reduction outcomes in the South. You only have to look to international agreements such the 2002 Monterrey Consensus or the2005 Paris Declaration for evidence of this. -

China's International Poverty Reduction Center as a Platform for South-South Learning
( 2010-10)After attending a South-South experience-sharing event in China, a number of African officials wondered: "How come China is able to develop and retain its implementation capacity, whereas our countries suffer from brain-drain?"
