Commodity Market Reforms : Lessons of Two Decades
(Washington, DC: World Bank, 2001-03)Structural reform of the economies of developing countries has been in the forefront of development interest since the early 1980s. This interest stems from a recognition that the structures and institutions of these countries are critical to any enhancement of economic and social development. One of the key reforms has been that of primary commodity markets, especially agricultural commodity markets, because many developing countries, including the poorest, depend heavily on these for foreign exchange earnings and employment, and hence for poverty reduction. This report focuses on the political economy and institutional aspects of agricultural commodity market reform. In order to explore in detail factors that are critical to the processes, consequences, and substance of reform, the authors have focused the analysis and evaluation on five commodities important in many developing countries, specifically cocoa, coffee, sugar, cotton, and cereal. In doing so, they highlight important lessons on how agricultural sector reform can be launched and implemented. Some of the factors identified in the report as being key to successful reform include the recognition that commodity markets often affect communities and even politics, that the initial conditions of markets are critical, and that government intervention can crowd out private sector initiatives, especially when it comes to building the institutions needed to develop a healthy agricultural sector. -

Determinants of Agricultural Growth in Indonesia, the Philippines, and Thailand
(World Bank, Washington, D.C., 2002-03)The introduction of new high-yielding varieties of cereals in the 1960s, known as the green revolution. Changed dramatically the food supply I Asia, as well as in other countries. The authors examine over an extended period, the growth consequences for agriculture in Indonesia, the Philippines, and Thailand. Despite geographic proximity, similar climate, and other shared characteristics, gains in productivity, and income differed significantly among the countries. The authors quantify these differences, and examine their determinants. They find that the new technology changed the returns to fertilizers, irrigated land, and capital, all of which proved scarce to varying degrees, Complementing technology-related changes in factor use were investments - public and private - driven in part by policy. The authors find that factor accumulation played an important role in output growth, and that accumulations from policy-driven investments in human capital, and public infrastructure, were important sources of productivity gains. They conclude that policies that ease constraints on factor markets, and promote public investment in people, and infrastructure, provide the best opportunities for agricultural growth. -

Policies on Managing Risk in Agricultural Markets
(World Bank, 2004-09-01)Over the past dozen years, policymakers have largely abandoned long-standing popular approaches for addressing risk in agriculture without fully resolving the question of how best to manage the negative consequences of volatile agricultural markets. The article reviews the transition from past policies and describes current approaches that distinguish between the trade-related fiscal consequences of commodity market volatility and the consequences of price and production risks for vulnerable rural households and communities. Current policies rely more heavily on markets, even though markets for risk are incomplete in numerous ways. The benefits and limitations of market-based instruments are examined in the context of risk management strategies, and innovative approaches to extend the reach of risk markets are discussed. -

How Endowments, Accumulations, and Choice Determine the Geography of Agricultural Productivity in Ecuador
(Oxford University Press on behalf of the World Bank, 2006-09-01)Spatial disparity in incomes and productivity is apparent across and within countries. Most studies of the determinants of such differences focus on cross-country comparisons or location choice among firms. Less studied are the large differences in agricultural productivity within countries related to concentrations of rural poverty. For policy, understanding the determinants of this geography of agricultural productivity is important, because strategies to reduce poverty often feature components designed to boost regional agricultural incomes. Census and endowment data for Ecuador are used to estimate a model of endogenous technology choice to explain large regional differences in agricultural output and factor productivity. A composite-error estimation technique is used to separate systemic determinants from idiosyncratic differences. Simulations are employed to explore policy avenues. The findings suggest a differentiation between the types of policies that promote growth in agriculture generally and those that are more likely to assist the rural poor. -

A Conceptual Model of Incomplete Markets and the Consequences for Technology Adoption Policies in Ethiopia
(World Bank, Washington, DC, 2013-10)In Africa, farmers have been reluctant to take up new varieties of staple crops developed to boost smallholder yields and rural incomes. Low fertilizer use is often mentioned as a proximate cause, but some believe the problem originates with incomplete input markets. As a remedy, African governments have introduced technology adoption programs with fertilizer subsidies as a core component. Still, the links between market performance and choices about using fertilizer are poorly articulated in empirical studies and policy discussions, making it difficult to judge whether the programs are expected to generate lasting benefits or to simply offset high fertilizer prices. This paper develops a conceptual model to show how choices made by agents supplying input services combine with household livelihood settings to generate heterogeneous decisions about fertilizer use. An applied model is estimated with data from a panel survey in rural Ethiopia. The results suggest that adverse market conditions limit the adoption of fertilizer-based technologies, especially among resource-poor households. Farmers appear to respond to market signals in the aggregate and this provides a pathway for subsidies to stimulate demand. However, the research suggests that lowering transaction costs, through investments in infrastructure and market institutions, can generate deeper effects by expanding the technologies available to farmers across all pricing outcomes. -

Intersectoral Migration in Southeast Asia : Evidence from Indonesia, Thailand, and the Philippines
(World Bank, Washington, DC, 2003-01)Using time series data spanning three decades, the authors examine the determinants of sectoral migration in Indonesia, Thailand and the Philippines. They employ a principal components algorithm to address problems associated with trended and inter-correlated explanatory variables. Migration rates in the three countries are low relative to other developing countries with the consequence of persistent inter-sectoral income differentials. Even so, the rate of migration has been responsive to income ratios in each country. The migration rates were also affected by the absorbing capacity of non-agriculture, as indicated by several measures. In contrast to other studies, policy variables consisting of indicators of physical and human capital had little impact on the migration rate separate from that captured by relative incomes. -

Should African Rural Development Strategies Depend on Smallholder Farms? An Exploration of the Inverse Productivity Hypothesis
(World Bank, Washington, DC, 2012-09)In Africa, most development strategies include efforts to improve the productivity of staple crops grown on smallholder farms. An underlying premise is that small farms are productive in the African context and that smallholders do not forgo economies of scale -- a premise supported by the often observed phenomenon that staple cereal yields decline as the scale of production increases. This paper explores a research design conundrum that encourages researchers who study the relationship between productivity and scale to use surveys with a narrow geographic reach, when policy would be better served with studies based on wide and heterogeneous settings. Using a model of endogenous technology choice, the authors explore the relationship between maize yields and scale using alternative data. Since rich descriptions of the decision environments that farmers face are needed to identify the applied technologies that generate the data, improvements in the location specificity of the data should reduce the likelihood of identification errors and biased estimates. However, the analysis finds that the inverse productivity hypothesis holds up well across a broad platform of data, despite obvious shortcomings with some components. It also finds surprising consistency in the estimated scale elasticities. -

Aligning Climate Change Mitigation and Agricultural Policies in Eastern Europe and Central Asia
(World Bank, Washington, DC, 2012-06)Greenhouse gas emissions are largely determined by how energy is created and used, and policies designed to encourage mitigation efforts reflect this reality. However, an unintended consequence of an energy-focused strategy is that the set of policy instruments needed to tap mitigation opportunities in agriculture is incomplete. In particular, market-linked incentives to achieve mitigation targets are disconnected from efforts to better manage carbon sequestered in agricultural land. This is especially important for many countries in Eastern Europe and Central Asia where once-productive land has been degraded through poor agricultural practices. Often good agricultural policies and prudent natural resource management can compensate for missing links to mitigation incentives, but only partially. At the same time, two international project-based programs, Joint Implementation and the Clean Development Mechanism, have been used to finance other types of agricultural mitigation efforts worldwide. Even so, a review of projects suggests that few countries in Eastern Europe and Central Asia take full advantage of these financing paths. This paper discusses mitigation opportunities in the region, the reach of current mitigation incentives, and missed mitigation opportunities in agriculture. The paper concludes with a discussion of alternative policies designed to jointly promote mitigation and co-benefits for agriculture and the environment. -

Uzbekistan : Strengthening the Horticulture Value Chain
(World Bank, Washington, DC, 2015-01)Why produce a policy note on horticulture in Uzbekistan? There are several answers to this existential question, although they are not necessarily obvious ones. Agriculture, taken as a whole, constitutes a small and declining share of Uzbekistan s national income, and horticulture is a small share of agricultural income. Even so, it is an important source of income for the 4.7 million households that operate dehkan farms in rural and disproportionally poor communities. Horticultural products are grown on an additional 21 thousand larger private farms as well. Evidence in this note suggests that growing fruit and vegetables is among the most profitable activities on both dehkan and private farms and, over the last ten years, the incomes those activities generate comprised a growing share of national GDP. Horticultural export earnings have also surged in recent years, growing from USD 373 million in 2006 to USD 1.16 billion in 2010. Uzbekistan has special agro-ecological conditions that set it apart from most countries and provides the basis for its horticulture subsector. Like agriculture as a whole, the subsector benefits greatly from policies that support basic research in agronomy and post-harvest technologies, from policies that support private investment and efficient markets, and from policies that promote the good stewardship of natural resources. The policy note is centered on the horticultural subsector. However, because an effort is made to draw comparisons between the policy environment that prevails for dehkan farmers and private farmers growing horticultural crops and that which is relevant for private farmers growing wheat and cotton, the note touches on many sector-wide issues. Still, it is important to emphasize that this policy note should not be viewed as a general review of agricultural policies. Finding ways to adapt policy lessons from horticulture to improve agricultural productivity as a whole is a more ambitious task and one that requires broader analysis and discussion. -

Using Markets to Deal with Commodity Price Volatility : What Can Governments and Donors Do to Develop Markets that Ameliorate Commodity Price Volatility?
(World Bank, Washington, DC, 1999-01)Commodities are often at the heart of local and sometimes national economies. Commodity prices are notoriously volatile, creating instability and uncertainty for commodity-dependent developing countries. Commodity price instability undermines economic growth and skews the distribution of income. As a result, nearly every government has tried to manage commodity price risks. This Note discusses different sets of commodity pricing policies and the barriers to their risk management.
