Cereal Prices and Child Undernutrition in Ethiopia
(Taylor and Francis, 2021-07-06)This paper looks at how changing cereal prices affect child undernutrition in Ethiopia. It derives height for age (stunting) and weight for height (wasting) as indicators of child undernutrition from the two most recent years of the Livings Standards Measurement Survey and utilizes market prices for key cereals, teff, wheat, and maize at the enumeration area across all regions of the country. Using a panel data fixed effects model, the analysis finds that, contrary to previous studies, rising cereal prices are positively associated with improved child stunting rates for children between ages 6 months and 5 years. There is no evidence to suggest that cereal prices have a significantly greater impact on height for age for children that come from households who are net sellers of these crops. Cereal prices do not appear to be associated with wasting, which is a shorter-term negative health outcome. -

Rural Roads, Poverty, and Resilience: Evidence from Ethiopia
(Taylor and Francis, 2020-10)This study analyses the linkage between the recent rural road development and household welfare, resilience, and economic conditions in Ethiopia. The empirical approach relies on a difference-in-differences matching method, taking advantage of a nationally representative household survey and an original road database, both of which are panel data spanning the period 2012–2016. The results of the econometric analysis suggest that Ethiopia’s rural road development was associated with a significant increase in household welfare or significant smaller losses in household consumption during the severe droughts. In addition, rural roads in very remote areas were associated with farmers’ sales of a larger share of their harvests and higher chance of fertiliser use. Rural road development was also associated with a higher likelihood of earning income from wage employment, particularly for women and youth. Taken together, the results suggest that, by connecting remote communities to markets and the main road network, rural roads have substantially supported the welfare and resilience of rural households in shock-prone Ethiopia. -

Games as Boundary Objects: Charting Trade-offs in Sustainable Livestock Transformation
(Taylor and Francis, 2020-03-27)Attempts to structurally transform segments of the agri-food system inevitably involve trade-offs between the priorities of actors with different incentives, perspectives and values. Trade-offs are context-specific, reflecting different socio-economic and political realities. We investigate the potential of structured boundary objects to facilitate exposing and reconciling these trade-offs within the context of multi-stakeholder social learning processes with pastoral and mixed crop-livestock communities in Burkina Faso, Ethiopia and Tanzania. Building on boundary objects as items flexible enough to be understood by all without having one common definition, structured boundary objects visualize actors’ input in a comparable format to facilitate knowledge sharing. Stakeholders in each country used a simulation tool and board game to explore the implications of changing livestock stocking and management practices for the environment and for actors’ future socio-economic priorities. Using structured boundary objects elicited trade-offs between household food and animal feed, and between livestock for income, labor, and/ or cultural functions, reflecting the context-specific and subjective evaluations actors make when attempting to plan livelihood changes. Our findings suggest to policy and decision-makers that sustainable transition plans can be developed when stakeholders in local agri-food systems employ approaches that allow shared understandings of trade-offs inherent to sustainable agriculture to emerge. -

Port Rail Connectivity and Agricultural Production: Evidence from a Large Sample of Farmers in Ethiopia
(Taylor and Francis, 2019-03-27)Agriculture important in Africa, employing a large share of the labor force and earning foreign exchange. Transport connectivity has long been a crucial constraint in the region. In theory, railways have the advantage of shipping bulky freight, such as fertilizer, at low costs. However, in many African countries, railways were in virtual bankruptcy in the 1990s. Using a large sample of data comprised of more than 190,000 households over eight years in Ethiopia, the paper estimates the impacts of rail transport on agricultural production. The paper takes advantage of the historical event that a major rail line connecting the country to Port Djibouti was abandoned during the 2000s. With the fixed effects and instrumental variable techniques combined, an agricultural production function is estimated. It is found that deteriorated transport accessibility to the port had a significantly negative impact. The use of fertilizer particularly decreased with increased transport costs. -

Land Ownership and Technology Adoption Revisited: Improved Maize Varieties in Ethiopia
(Elsevier, 2018-03)The lack of land ownership can discourage agricultural technology adoption, yet there is scarce evidence of the impact of land rental contracts on the adoption of improved crop varieties in developing countries. The current study investigates such impact using a nationally representative survey of Ethiopian maize farmers. In contrast to many previous studies, we show in a simple model that cash-renters are as likely to adopt improved maize varieties as owner-operators, while sharecroppers are more likely to adopt given that such varieties are profitable. Empirical analysis reveals a significant impact of sharecropping on improved maize variety adoption, and no significant impact from cash-rental, lending support to the above hypotheses. These results imply that improvements in land rental markets can potentially enhance household welfare through crop variety adoption in agrarian economies where land sales markets are incomplete or missing. -

Land Productivity and Plot Size: Is Measurement Error Driving the Inverse Relationship?
(Elsevier, 2018-01)This paper revisits the decades-old puzzle of the inverse plot-size productivity relationship (IR), which states that land productivity decreases as plot size increases. While existing studies define land productivity or yields as self-reported production divided by plot size, we consider an alternative approach to estimating yields based on crop cuts. The crop-cut method entails measuring and harvesting randomly selected subplots by trained technicians, and is recommended by the Food and Agricultural Organization for the accurate measurement of crop production. Using data of rural Ethiopia, our analysis indicates that the IR is strong when based on self-reported production, but disappears when based on crop-cut estimates. Our inference from these findings is that the IR is an artifact of systematic over-reporting of production by farmers on small plots, and under-reporting on larger plots. We also discuss how rejecting the inverse plot-size productivity relationship has significant implications for the inverse farm-size productivity relationship. -

Prevalence, Economic Contribution, and Determinants of Trees on Farms across Sub-Saharan Africa
(Elsevier, 2017-11)Trees on farms are often overlooked in agricultural and natural resource research and policy in Sub-Saharan Africa. This article addresses this gap using data from the Living Standards Measurement Study-Integrated Surveys on Agriculture in five countries: Ethiopia, Malawi, Nigeria, Tanzania, and Uganda. Trees on farms are widespread. On average, almost a third of rural smallholders grow trees. They account for an average of 17% of total annual gross income for tree-growing households and 6% for all rural households. Gender, land and labor endowments, and especially forest proximity and national context are key determinants of on-farm tree adoption and management. These new, national-scale insights on the prevalence, economic contribution and determinants of trees on farms in Africa lay the basis for exploring the interaction of agriculture, on-farm tree cultivation, and forestry to gain a more complete picture of the dynamics of rural livelihoods across the continent and beyond. -

Direct and Indirect Effects of Malawi's Public Works Program on Food Security
(Elsevier, 2017-09)Labor-intensive public works programs are important social protection tools in low-income settings, intended to supplement the income of poor households and improve public infrastructure. In this evaluation of the Malawi Social Action Fund, an at-scale, government-operated program, across- and within-village randomization is used to estimate effects on food security and use of fertilizer. There is no evidence that the program improves food security and suggestive evidence of negative spillovers to untreated households. These disappointing results hold even under modifications to the design of the program to offer work during the lean rather than harvest season or increase the frequency of payments. These findings stand in contrast to those from large public works programs in India and Ethiopia, and serves as a reminder that public works programs will not always have significant and measurable welfare effects. -

Examining Changes in Maternal and Child Health Inequalities in Ethiopia
(Springer, 2017-08-22)Ethiopia has made considerable progress in maternal, newborn, and child health in terms of health outcomes and health services coverage. This study examined how different groups have fared in the process. It also looked at possible factors behind the inequalities. The study examined 11 maternal and child health outcomes and services: stunting, underweight, wasting, neonatal mortality, infant mortality, under-5 mortality, measles vaccination, full immunization, modern contraceptive use by currently married women, antenatal care visits, and skilled birth attendance. It explored trends in inequalities by household wealth status based on Demographic and Health Surveys conducted in 2000, 2005, 2011, and 2014. The study also investigated the dynamics of inequality, using concentration curves for different years. Decomposition analysis was used to identify the role of proximate determinants. -

Explaining Ethiopia’s Growth Acceleration—The Role of Infrastructure and Macroeconomic Policy
(Elsevier, 2017-08)Ethiopia has experienced an impressive growth acceleration over the past decade. This was achieved on the back of an economic strategy emphasizing public infrastructure investment supported by heterodox macro-financial policies. This paper identifies the drivers of Ethiopia’s recent growth episode and examines the extent to which they were typical or unique. It combines country-specific information with the results of a cross-country panel regression model. We find that Ethiopia’s growth is explained well by factors correlating with growth in a broad range of countries in recent decades, including public infrastructure investment, restrained government consumption, and a conducive external environment. On the other hand, we argue that the policy mix that supported very high levels of public investment in Ethiopia was, to some extent, unique. Interestingly, macroeconomic imbalances due to this heterodox policy mix only moderately held back growth which helps explain why Ethiopia was able to grow so fast in spite of their presence: their negative effects were quantitatively much less important than the positive growth drivers they helped to achieve. The results suggest that “getting infrastructure right” may outweigh moderate shortcoming in the macro framework at early stages of development. We further relate this country-specific finding to the recent growth literature.
