Mismeasurement and efficiency estimates: Evidence from smallholder survey data in Africa by Abay, Kibrom A.,Wossen, Tesfamicheal,Chamberlin, Jordan Pdf

Smallholder agriculture in sub-Saharan Africa is commonly characterized by high levels of technical inefficiency. However, much of this characterization relies on self-reported input and production data, which are prone to systematic measurement error. We theoretically show that non-classical measurement error introduces multiple identification challenges and sources of bias in estimating smallholders’ technical inefficiency. We then empirically examine the implications of measurement error for the estimation of technical inefficiency using smallholder farm survey data from Ethiopia, Malawi, Nigeria, and Tanzania. We find that measurement error in agricultural input and production data leads to a substantial upward bias in technical inefficiency estimates (by up to 85 percent for some farmers). Our results suggest that existing estimates of technical efficiency in sub-Saharan Africa may be severe underestimates of smallholders’ actual efficiency and what is commonly attributed to farmer inefficiency may be an artifact of mismeasurement in agricultural data. Our results raise questions about the received wisdom on African smallholders’ production efficiency and prior estimates of the productivity of agricultural inputs. Improving the measurement of agricultural data can improve our understanding of smallholders’ production efficiencies and improve the targeting of productivity-enhancing technologies.

The economics of teff: Exploring Ethiopia’s biggest cash crop by Minten, Bart,Taffesse, Alemayehu Seyoum,Brown, Petra Pdf

Considerable poverty and food insecurity in Ethiopia, combined with the overwhelming majority of Ethiopians who depend on agriculture for their livelihoods, make agricultural transformation a crucial development goal for the country. One promising improvement is to increase production of teff, the calorie- and nutrient-rich but low-yielding staple. The Economics of Teff: Exploring Ethiopia’s Biggest Cash Crop examines key aspects of teff production, marketing, and consumption, with a focus on opportunities for and challenges to further growth. The authors identify ways to realize teff’s potential, including improving productivity and resilience, selecting and scaling up new technologies, establishing distribution systems adapted to different areas’ needs, managing labor demand and postharvest operations, and increasing access to larger and more diverse markets. The book’s analysis and policy conclusions should be useful to policy makers, researchers, and others concerned with Ethiopia’s economic development.

Weather and Climate Services in Europe and Central Asia by Anonim Pdf

Weather and Climate Services in Europe and Central Asia is part of the World Bank Working Paper series. These papers are published to communicate the results of the Bank's ongoing research and to stimulate public discussion. Worldwide, the accuracy and value of weather and climate services are rising, bringing great economic benefits. However, many national hydrometeorological services in Europe and Central Asia are in decline. As a result, these potential gains are often missed. Much more could be done to mitigate weather disasters, support the productivity of smallholding and commercial agriculture, conserve energy, and promote safe aviation and transport by road and rail. Although capacity deficiencies are serious, they could be remedied significantly by relatively modest-but sustained-investments. Chapter 1 describes the worldwide growth in weather forecasting skill, presents principal issues and questions in Europe and Central Asia (ECA), and sets out the study's organization. Chapter 2 assesses the needs of the key sectoral clients of the national hydrometeorological services in the region. Chapter 3 addresses ECA's natural weather and climate issues: vulnerability to transboundary weather events, extreme weather, variable weather, and projected climate change. Chapter 4 presents the forecasting workflow, and then presents key regional and national capacity gaps. Chapter 5 discusses ways to estimate the economic benefit of existing and upgraded forecasting capacity. This study is part of an ongoing Regional Working Paper Series sponsored by the Chief Economist's Office in the Europe and Central Asia Region of the World Bank.

Harvesting Prosperity by Keith Fuglie,Madhur Gautam,Aparajita Goyal,William Francis Maloney Pdf

This book documents frontier knowledge on the drivers of agriculture productivity to derive pragmatic policy advice for governments and development partners on reducing poverty and boosting shared prosperity. The analysis describes global trends and long-term sources of total factor productivity growth, along with broad trends in partial factor productivity for land and labor, revisiting the question of scale economies in farming. Technology is central to growth in agricultural productivity, yet across many parts of the developing world, readily available technology is never taken up. We investigate demand-side constraints of the technology equation to analyze factors that might influence producers, particularly poor producers, to adopt modern technology. Agriculture and food systems are rapidly transforming, characterized by shifting food preferences, the rise and growing sophistication of value chains, the increasing globalization of agriculture, and the expanding role of the public and private sectors in bringing about efficient and more rapid productivity growth. In light of this transformation, the analysis focuses on the supply side of the technology equation, exploring how the enabling environment and regulations related to trade and intellectual property rights stimulate Research and Development to raise productivity. The book also discusses emerging developments in modern value chains that contribute to rising productivity. This book is the fourth volume of the World Bank Productivity Project, which seeks to bring frontier thinking on the measurement and determinants of productivity to global policy makers.

Budget Support as More Effective Aid? by Stefan Koeberle,Zoran Stavreski,Jan Walliser Pdf

"Budget support has become an increasingly important instrument in the context of a partnership-based approach to development assistance. Compared to traditional modes of aid delivery, it promises greater country ownership, reduced transaction costs, better donor coordination, scaling up of poverty reduction and potentially greater development effectiveness. This book presents a timely and valuable review of key concepts, issues, experiences and emerging lessons relevant to budget support. It provides an overview of principal characteristics, expectations and concerns related to budget support, key design and implementation issues, as well as some practical experiences. The contributors include government representatives from developing countries, leading academic scholars, bilateral development agencies and development practitioners from international financial institutions, including the World Bank and the International Monetary Fund. They present a wide range of views on key issues such as the choice of instruments, alignment of budget support with country programs, predictability, and coordination and conditionality. The authors draw their insightful analysis on the contemporary research and evaluation work, as well as the broad practical experience with budget support. This book will be of great interest to practitioners in aid-recipient countries and international financial institutions, bilateral agencies and civil organizations involved in budget support."

The Oxford Handbook of Economic Imperialism by Zak Cope,Immanuel Ness Pdf

"The Oxford Handbook of Economic Imperialism examines unequal commercial, trade, and investment gains at the international level and explores how countries and nations can have exploitative relations. The book contains thirty-four chapters written by academics and experts in the field of international political economy. The chapters in the Handbook look at the history of economic imperialism from the early modern age to the present. They demonstrate the persistence of economic imperialism in today's postcolonial world and the enduring control wielded by great powers even after the end of formal empire. The book reveals how emerging powers are expanding economic control in new geographic and geopolitical contexts. The Handbook highlights the significance of economic imperialism in the structures, relations, processes, and ideas that help sustain poverty and conflict worldwide"--

An African Green Revolution by Keijiro Otsuka,Donald F. Larson Pdf

This volume explores the usefulness of the Asian model of agricultural development for Africa, where, even before the recent world food crisis, half the population lived on less than on dollar a day, and a staggering one in three people and one third of all children were undernourished. Africa has abundant natural resources; agriculture provides most of its jobs, a third of national income and a larger portion of total export earnings. However the levels of land and labor productivity rank among the worst in the world. The book explains Africa’s productivity gap and proposes ways to close it, by examining recent experience in Africa and by drawing on lessons from Asia.

African Farmers, Value Chains and Agricultural Development by Alan de Brauw,Erwin Bulte Pdf

This book provides a thorough introduction to and examination of agricultural value chains in Sub-Saharan Africa. First, the authors introduce the economic theory of agri-food value chains and value chain governance, focusing on domestic and regional trade in (and consumption of) food crops in a low-income country context. In addition to mainstream and heterodox thinking about value chain development, the book pays attention to political economy considerations. The book also reviews the empirical evidence on value chain development and performance in Africa. It adopts multiple lenses to examine agricultural value chains, zooming out from the micro level (e.g., relational contracting in a context of market imperfections) to the meso level (e.g., distributional implications of various value chain interventions, inclusion of specific social groups) and the macro level (underlying income, population and urbanization trends, volumes and prices, etc.).Furthermore, this book places value chain development in the context of a process the authors refer to as structural transformation 2.0, which refers to a process where production factors (labor, land and capital) move from low-productivity agriculture to high-productivity agriculture. Finally, throughout the book the authors interpret the evidence in light of three important debates: (i) how competitive are rural factor and product markets, and what does this imply for distribution and innovation? (ii) what role do foreign investment and factor proportions play in the development of agri-food value chains in Africa? (iii) what complementary government policies can help facilitate a process of agricultural value chain transformation, towards high-productive activities and enhancing the capacity of value chains to generate employment opportunities and food security for a growing population.
