摘要:

AbstractThis study investigates the demand relationships for 16 food commodities and a nonfood category in Japan through the estimation of the per household demand model of the Rotterdam system. It also attempts to assess the predictive power of the estimated model, and to inquire into recent trends in demand changes for food commodities. Estimates of total shift in demands were decomposed into average annual rates of shift in demands with respect to relative price, real income, family size and time. Policy implications of the results are discussed in detail. © 1993 John Wiley&Sons, Inc

摘要:

AbstractEconomies of size studies can be categorized according to the methodology employed. Two recent studies for cattle slaughtering and beef fabrication that varied widely in methodology and data were compared using a binary variable regression model. Despite differences in data and the methodology chosen, the comparative analysis showed that results from the two studies were similar. Estimated minimum costs and associated annual volumes were sensitive to inclusion or exclusion of the smallest plant size in one study. Minimum cost annual volumes varied over a relatively wide range, suggesting a flat long‐run average cost curve at higher volumes, with only a small effect on average total cost. © 1993 John Wiley&Sons, I

摘要:

AbstractFour marketing methods for slaughter cattle were analyzed and examined for pricing efficiency. Profits per head were found to be significantly different under the various marketing methods. Greater price discrimination occurred as carcass information increased. Increased price discrimination led to greater dispersion of profit from one marketing method to another. Different marketing methods appeared to send different production signals to producers. The desires of the consumer for less fat and a high‐quality product did not appear to be reaching the producers in the form of profit incentives under the most widely used marketing method. © 1993 John Wiley&Sons, I

摘要:

AbstractIn a study investigating the adoption of irrigation and drainage reduction technologies, a classification of farms predicated on the organizational characteristics of the firm was used to assess farm decision making with regard to resource use. Organizational classes represent farms that differ in size, technology, crop mix, or labor but that manage these and other resources similarly through their organizational structure. Organizational structure was the product of the farm's assignment of task roles, the formalization of rules and procedures surrounding the task, and the relationship between workers and the task. We identified five types of farm organizations—the unified organization, the primary hierarchy, the simple functional hierarchy, the complex functional hierarchy, and the market hierarchy—which were tested against common production resources to (1) determine the ability of our classification to differentiate farms according to these characteristics and (2) assess regional differences in the availability and quality of resources upon farm decision making. © 1993 John Wiley&Sons,

摘要:

AbstractIndia has exhibited a remarkable growth in total foodgrain production during the last 40 years. Total foodgrain production has increased by 236% with an annual growth rate of 2.74% during the period 1950/51–1989/90. Average production increased by 72% between periods 1950/51–1965/66 (pregreen revolution) and 1966/67–1989/90 (green revolution). These increases have been accompanied by higher instability and risk in production of certain crops. This study applies variance decomposition procedures to time series data on foodgrains to analyse the sources of instability. Statistical identities have been used to provide an exact decomposition of the components of change in mean and variance of production. The coefficient of variation and variance of total foodgrain production increased by 6.97 and 239.65%, respectively, between the two periods. © 1993 John Wiley&Son

摘要:

AbstractThe agricultural sector is coming under increasing scrutiny as to its contribution to environmental degradation. The concepts of corporate social responsibility and environmental and product liability suggest that agribusiness firms have a duty and are responsible not only for the environmental impacts of their production and distribution operations but in part for the environmental practices and impacts of those who use their products and from whom they acquire raw materials as well. More and more agribusiness firms are expected to develop environmentally responsible corporate policies that are substantiative in nature rather than simply public relations gestures. © 1993 John Wiley&Sons, Inc

摘要:

AbstractThe European Community's (EC) 1992 programme is designed to achieve an area without internal frontiers. If nontariff barriers threaten to restrict trade in processed foodstuffs, the EC has two complementary strategies to pursue. Food law harmonisation, to the extent required to ensure food safety, is one. The principle of mutual recognition is the second. The potential impact of mutual recognition on food manufacturers and consumers is reviewed. Mutual recognition, while striking down barriers to trade, does not create a single market. The EC is likely to resort to more, not less, harmonisation of food law in future years. © 1993 John Wiley&Sons, Inc

摘要:

AbstractThis article looks at agribusiness research as it is evolving in the broad, complicated social milieu of agribusiness concepts, especially education, politics, and organizational entities. Probably its most useful contribution is a research effort to define and measure the amount of agribusiness research being conducted in the US Department of Agriculture and the State Agricultural Experiment Stations. The article also gives selected directional guidelines for definition and development of future agribusiness research. © 1993 John Wiley&Sons, Inc
