Book Description
This book shows how decisions made by individual farmers influence the efficiency of agricultural markets. Unless farmers properly take account of the correlation between prices and yields in forming their price forecasts, competitive markets will often be socially inefficient, leading to misallocation of resources. The authors demonstrate that a simple and practical price forecasting rule, based on expected per unit revenue, is generally adequate to ensure efficient market behavior.Time-series data from various countries are used to test the hypothesis that market supply is influenced by the correlation of price and yield as well as by lagged market prices . The importance of market inefficiencies in risky situations is shown to, depend on the variability of yields, the nature of farmers'price forecasting behavior, the degree of private risk aversion,and the elasticity of demand. The authors suggest and evaluate three basic policy approaches governments may take when confronted with very inefficient markets--establishing production quotas, improving market information services, and implementing price stabilization schemes. They conclude by discussing implications of the study for the specification of agricultural supply models and for the economic appraisal of risky investment projects.

Book Description
Models of crop growth and development were conceived originally for scientific purposes. Typically, they describe the mechanisms of crop production, development from emergence through tuber initiation to senescence determined by temperature and day-length. Growth is driven by solar radiation intercepted by the foliage. Yields are enhanced by the availability of water and nutrients and may be reduced by pests, diseases and weeds. The scientific models describing the processes involved are leaving the research institutes and increasingly are becoming a means of knowledge transfer for students, and most importantly, to growers and their intermediaries such as extensionists and consultants. Many decision support systems (DSS) have a mechanistic model core that assures their robustness and reliability. This book gives an overview of model-based DSS in potato production. Decision support systems are used by the processing industry to guide them to promising production areas and by breeders to identify the ideal genotype for such environments. Consultants and soil laboratories use them as well as farmers to optimize the use of nitrogen, water and chemicals to control insects, nematodes, late blight and weeds. The systems, making use of models and sensing techniques, improve yield and quality while allowing their users to improve the efficiency of use of resources, thus generating positive effects for profits and for the environment. The book also gives examples of new introductions of DSS and farmers responses. The book is intended for researchers wanting to bring their models to practice, students to learn bout DSS, intermediaries and growers to improve the performance of the potato industry or of other commodities for which potato serves as an example.

Book Description
This book explores the policy implications of growing pressures for economic adjustment in the agricultural sectors of developed countries. The primary focus is on Europe and North America, but adjustment policies in other developed countries are discussed. Some chapters are based on an international workshop at Imperial College, London in October 2003 and an international symposium in Philadelphia in the spring of 2004.
