This book was released on 2013 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Consumer demand for food is an important component of the structure within which various agricultural and food policies have been formulated. For explicitly recognizing the interdependent demand relationships, a complete food demand system approach is desirable. This report contains a methodological blueprint for estimation and application of ordinary (quantity-dependent) and inverse (price-dependent) food demand systems in a unified framework. Both of the demand systems are theoretically consistent and practical for evaluating policy options related to controlling prices or supplies in the market. Each demand system is estimated for a U.S. food demand structure consisting of 13 food groups and one nonfood sector. Some empirical applications are provided to examine how economic factors influence the nutrient content of American diets and the consumer welfare measurements. The findings of this report are useful for applied economists and graduate students in economics, especially agricultural economics.

Available in PDF, EPUB and Kindle. Book excerpt: This article reports tests of aggregation over consumer food products and estimates of aggregate food demand elasticities. Evidence that food demand variables follow unit root processes leads us to build on and simplify existing tests of the Generalized Composite Commodity Theorem. We compute food demand elasticities using a method of cointegration that is shown to apply to a convenient but nonlinear functional form. Estimates are based on consumer reported expenditure data rather than commercial disappearance data.

Book excerpt: The four papers on aggregation theory and estimation of demand function together provide a complete picture starting from the underlying theory of aggregation and specification to empirical estimation of demand functions. The first paper is about the aggregation across consumers. The second paper explores the properties associated with the Constant Slutsky Elasticity (CSE) model which is closely related to the absolute price version of the Rotterdam Model. The third paper estimates a complete system of demand equations making full use of the restrictions implied by economic theory. This is done using the model formulated by Stone namely, Klein-Rubin. The fourth paper estimates a model of consumer behavior by pooling Canadian cross sectional and time series data. An attempt is made in this synthesis to collate the four papers and understand the entire theory behind demand functions and see how demand functions are estimated empirically after incorporating elements such as leisure, household size to make the theory fit the reality. The first half of the section will draw from the first two papers to understand the theory of aggregation. The following section will draw from the next two papers on empirical estimates to understand the application of theory.

This book was released on 2021-06-29 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook addresses the core issues facing economists concerning price determination in commodity markets, especially food and agricultural commodities. This book hones in on the conceptual basis of the various relationships, with special emphasis on market interrelationships, both horizontally and vertically. This book covers key concepts such as consumer demand theory; quality, heterogeneous goods, and cross section demand; derived demand, marketing margins, and relationship between output and raw material prices; retail-to-farm demand linkages, imperfect competition, and short-run price determination; dynamic consumer demand; and dynamic models of the firm. What makes this textbook of particular use to students is its focus on bridging the gap between theory and empirical analysis. Going from theory to empirics requires that we have data—time series or cross section—that match the theoretical constructs. Often the data match is not perfect, either by definition or how the data are computed. In addition to problems of matching data with theoretical constructs, students and researchers need to know how to specify, estimate, and interpret results within the context of imperfect and often incomplete data. This textbook uses several data sets to illustrate how one might address problems in real-world settings. Furthermore, with exercises at the end of each chapter, students are able to test themselves on their ability to bring theory to life.

Available in PDF, EPUB and Kindle. Book excerpt: "Many findings and policy recommendations in the academic literature are influenced by published estimates of elasticities of demand for food. However, the quality of these estimates is diverse and depends on modeling choices and assumptions, including the functional form for demands, types of data used, separability structure, food definitions, and statistical techniques used to estimate the models. In this monograph, we make three contributions to the empirical literature on demand for food in the United States. First, we evaluate the elasticities of demand for food from previous studies using the mean absolute error in elasticity-based predictions of quantity responses to actual past changes in prices and total expenditure. Second, we estimate elasticities of demand for aggregate food products using annual and monthly data under various alternative assumptions about functional form. We evaluate how well these new estimates of elasticities of demand predict quantity responses to actual price and expenditure changes, both absolutely and compared with previous estimates from the literature. Third, we estimate two sets of elasticities of demand for disaggregated fruit and vegetables: one that is conditional on the total expenditure on fruit and vegetables and a second that is conditional on expenditure on goods. To facilitate and provide context for these empirical contributions, we begin the monograph with a succinct statement of the relevant theory that underpins demand models, some specific discussion of separability and aggregation assumptions and their implications for the interpretation of demand elasticities, and a review of issues more generally that arise in empirical demand analysis."--Executive summary.

Available in PDF, EPUB and Kindle. Book excerpt: Extract: Three food demand estimation procedures were compared to find which best measures the structure of food demand. These procedures were Semmingly Unrelated Regression, Block Additive, and Ordinary Least Squares. The focus was on food commodity substitution. The comparison of results was made on the basis of commodity demand and net change in calories consumed as estimated by each procedure. Each procedure projects a similar pattern of commodity demand and net caloric intake change. Overall, the Seemingly Unrelated Regression procudure provides the most reasonable and consistent results.

This book was released on 2015-01-02 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States Department of Agriculture's (USDA's) Economic Research Service's (ERS) Food Availability Data System includes three distinct but related data series on food and nutrient availability for consumption. The data serve as popular proxies for actual consumption at the national level for over 200 commodities (e.g., fresh spinach, beef, and eggs). The core Food Availability (FA) data series provides data on the amount of food available, per capita, for human consumption in the United States with data back to 1909 for many commodities. The Loss-Adjusted Food Availability (LAFA) data series is derived from the FA data series by adjusting for food spoilage, plate waste, and other losses to more closely approximate 4 actual intake. The LAFA data provide daily estimates of the per capita availability amounts adjusted for loss (e.g., in pounds, ounces, grams, and gallons as appropriate), calories, and food pattern equivalents (i.e., "servings") of the five major food groups (fruit, vegetables, grains, meat, and dairy) available for consumption plus the amounts of added sugars and sweeteners and added fats and oils available for consumption. This fiscal year, as part of its initiative to systematically review all of its major data series, ERS decided to review the FADS data system. One of the goals of this review is to advance the knowledge and understanding of the measurement and technical aspects of the data supporting FADS so the data can be maintained and improved. Data and Research to Improve the U.S. Food Availability System and Estimates of Food Loss is the summary of a workshop convened by the Committee on National Statistics of the National Research Council and the Food and Nutrition Board of the Institute of Medicine to advance knowledge and understanding of the measurement and technical aspects of the data supporting the LAFA data series so that these data series and subsequent food availability and food loss estimates can be maintained and improved. The workshop considered such issues as the effects of termination of selected Census Bureau and USDA data series on estimates for affected food groups and commodities; the potential for using other data sources, such as scanner data, to improve estimates of food availability; and possible ways to improve the data on food loss at the farm and retail levels and at restaurants. This report considers knowledge gaps, data sources that may be available or could be generated to fill gaps, what can be learned from other countries and international organizations, ways to ensure consistency of treatment of commodities across series, and the most promising opportunities for new data for the various food availability series.
