Commodities have become an important component of many investors' portfolios and the focus of much political controversy over the past decade. This book utilizes structural models to provide a better understanding of how commodities' prices behave and what drives them. It exploits differences across commodities and examines a variety of predictions of the models to identify where they work and where they fail. The findings of the analysis are useful to scholars, traders and policy makers who want to better understand often puzzling - and extreme - movements in the prices of commodities from aluminium to oil to soybeans to zinc.

All major U.S. agricultural program crops -- corn, barley, sorghum, oats, wheat, rice, and soybeans -- have exhibited extreme price volatility since mid-2007, while rising to record or near-record levels in early 2008. Several international organisations have announced that the sharply rising commodity prices are likely to have dire consequences for the world's vulnerable populations, particularly in import-dependent, less developed nations. In the United States, high commodity prices have pushed farm income to successive annual records and have sharply lowered government farm program costs, but they have also stoked the flames of food price inflation and have raised costs for livestock producers and food processors. In addition, high, unexpectedly volatile prices have increased the risk and costs associated with grain merchandising. In particular, they have dramatically increased the cost of routine hedging activities (i.e., pricing commodities for purchase, delivery, or use at some future date) at commodity futures exchanges and, as a result, have diminished "forward contracting" opportunities for grain and oilseed producers who are eager to take advantage of record high market prices. For some crops (particularly for wheat and rice), the price increases are likely to be relatively short-term in nature and are due to weather-related crop shortfalls in major producer and consumer countries, a weak U.S. dollar that has helped spark large increases in U.S. exports, a bidding war among major U.S. crops for land in the months leading up to spring planting in 2008, and the often perverse price effects resulting from international policy responses by several major exporting and importing nations to protect their domestic markets. Assuming a return to normal weather, these factors will likely self-correct within two growing seasons as global supplies are replenished and prices moderate. For coarse grains (corn, sorghum, barley, oats, and rye), oilseeds, and oilseed products (e.g., vegetable oil and meal), the price increases have also been due to strong, sustained demand deriving from two sources: robust income growth in developing countries (e.g., China and India), which has contributed to increased demand for meat products and the feed grains needed to produce that meat; and growing agricultural feedstock demand to meet large increases in government biofuel-usage mandates or goals in the United States, the European Union, and other countries. Market analysts, including the United Nations' Food and Agricultural Organization (FAO), are predicting record global grain and oilseed production in 2008 in response to the high market prices. However, given the overall strength in demand growth, most market analysts predict that when commodity supplies eventually recover and prices moderate from current high levels, the new equilibrium prices will be significantly higher than has traditionally been observed during periods of market balance. This book examines the causes, consequences, and outlook for prices of the major U.S. program crops

The April 2012 issue of the World Economic Outlook assesses the prospects for the global economy, which has gradually strengthened after a major setback during 2011. The threat of a sharp global slowdown eased with improved activity in the United States and better policies in the euro area. Weak recovery will likely resume in the major advanced economies, and activity will remain relatively solid in most emerging and developing economies. However, recent improvements are very fragile. Policymakers must calibrate policies to support growth in the near term and must implement fundamental changes to achieve healthy growth in the medium term. Chapter 3 examines how policies directed at real estate markets can accelerate the improvement of household balance sheets and thus support otherwise anemic consumption. Chapter 4 examines how swings in commodity prices affect commodity-exporting economies, many of which have experienced a decade of good growth. With commodity prices unlikely to continue growing at the recent elevated pace, however, these economies may have to adapt their fiscal and other policies to lower potential output growth in the future.

This book provides fresh insights into concepts, methods and new research findings on the causes of excessive food price volatility. It also discusses the implications for food security and policy responses to mitigate excessive volatility. The approaches applied by the contributors range from on-the-ground surveys, to panel econometrics and innovative high-frequency time series analysis as well as computational economics methods. It offers policy analysts and decision-makers guidance on dealing with extreme volatility.

This comprehensive overview of local food systems explores alternative definitions of local food, estimates market size and reach, describes the characteristics of local consumers and producers, and examines early indications of the economic and health impacts of local food systems. Defining ¿local¿ based on marketing arrangements, such as farmers selling directly to consumers at regional farmers¿ markets or to schools, is well recognized. Statistics suggest that local food markets account for a small, but growing, share of U.S. agricultural production. For smaller farms, direct marketing to consumers accounts for a higher percentage of their sales than for larger farms. Charts and tables.

The recent global financial crisis exposed the serious limitations of existing economic and financial models. Not only did macro models fail to predict the crisis, they seemed incapable of explaining what was happening to the economy. Policymakers felt abandoned by the conventional tools of the now obsolete Washington consensus and the World Trade Organization’s oversimplified faith in free markets.The traditional models for agricultural commodities have so far failed to take into account the uncertain character of the global agricultural economy and its ferocious consequences in food price volatility, the worst in 300 years, yielding hunger riots throughout the world. This book explores the elements which could help to close this fundamental modeling gap. To what extent should traditional models be questioned regarding agricultural commodities? Are prices on these markets foreseeable? Can their evolution be either predicted or convincingly simulated, and if so, by which methods and models? Presenting contributions from acknowledged experts from several countries and backgrounds – professors at major international universities or researchers within specialized international organizations – the book concentrates on four issues: the role of expectations and capacity of prediction; policy issues related to development strategies and food security; the role of hoarding and speculation and finally, global modeling methods. The book offers a renewed wisdom on some of the core issues in the world economy today and puts forward important innovations in analyzing these core issues, among which the modular modeling design, the Momagri model being a seminal example of it. Reading this book should inspire fruitful revisions in policy-making to improve the welfare of populations worldwide.
