This article determines the relative technical efficiency of rural- and urban-influenced crop/livestock enterprises in the Corn Belt. Farmers in urban-influenced locations are less technically efficient than farmers in rural locations. During 1998–2000, stochastic production frontier procedures indicate that a 10% increase in urban influence leads to a close to 4% decrease in technical efficiency. The most successful urban-influenced farms have controlled costs as effectively as rural farms. They have tended to de-emphasize that nondairy livestock activities—particularly beef and hogs—do not rely extensively on off-farm income, and have relatively large, less residential/lifestyle operations compared to less successful urban-influenced farmers. However, our statistical analysis clearly bears out the refrain in popular literature that urban proximity raises the cost for, and decreases the viability of, traditional farms.  相似文献

We use line integral theory to lay out in a more general theoretical framework the conditions under which it is possible to measure with market data the welfare effects of a change in a nonmarket good. We present in detail a numerical method of measuring the value of nonmarket goods using market data, under either weak neutrality or weak complementarity. Our numerical method is more flexible than the existing analytical method because it can be used with any well-behaved Marshallian demand function, and can be used even when the willig condition does not hold.  相似文献

This paper explores the landscape of training and development in the Republic of Ireland, a country with an impressive economic record in recent years. Both the Irish economic context and business context are explored. The national system for training and development and the surrounding policy and strategy context are set down. Survey data are drawn upon to examine the nature of training and development at organizational level. Here influence on training and development, levels of expenditure, the number of days per employee category and the dominant methods employed training and development are all discussed. Finally the academic study of training and development in the Republic of Ireland is examined.  相似文献

This paper examines the potential impacts of U.S. mandatory country of origin labeling. North American hog and pork markets are represented as vertically related in a partial equilibrium non-spatial model. A synthetic model is calibrated to historic data and then used to trace the program's added costs as they are passed through the market to determine who wins and who loses. The transactions costs reduce the welfare of all agents in the United States. Canadian welfare depends primarily on whether mixed supply chains continue to be accepted in the United States and trade in hogs continues. A closed border significantly reduces the welfare of Canadian hog producers and increases the welfare of Canadian pork processors.
Le présent article porte sur les répercussions éventuelles de l'étiquetage obligatoire du pays d'origine réclamée par les États‐Unis. Les marchés nord-américains du porc vivant et de la viande de porc sont représentés comme étant verticalement liés dans un modèle non spatial d'équilibre partiel. Un modèle synthétique est étalonné avec des données historiques et est ensuite utilisé pour déterminer les coûts supplémentaires qu'occasionne le programme à mesure qu'ils sont répartis sur le marché pour déterminer les gagnants et les perdants. Les coûts de transaction diminuent le bien‐être de tous les agents aux États‐Unis. Le bien-être au Canada dépend principalement de l'acceptation ou non des chaînes d'approvisionnement mixtes et de la continuité ou non du commerce du porc vivant. La fermeture des frontières diminue considérablement le bien-être des producteurs de porcs canadiens et augmente celui des transformateurs de porcs canadiens.  相似文献

The structure of marketing channel relationships   总被引:3,自引:0,他引:3  
Distribution channel research has been advanced in recent years by contributions based on the political economy paradigm, transaction cost analysis, and relationship marketing. Drawing on these bodies of thought, we propose a new conceptualization of the structure of marketing channel relationships. Relationship structure is defined in terms of decision-making structure and operational integration. The proposed model of channel structure antecedents and consequences is consistent with the major research paradigms but extends beyond simple categorical assemblages of constructs to provide an ordered set of relationships based on theory and empirical research. This conceptualization reconciles some apparent contradictions in the literature and provides a clear focus for structure, process, and performance research in channels. He received his Ph.D. in marketing from Louisiana State University. He has published in the areas of marketing channels, retailing, and logistics. His work has appeared in theJournal of Marketing Research, Journal of Marketing, Journal of Retailing, Journal of Business Research, Journal of Marketing Channels, International Journal of Physical Distribution and Materials Management, Journal of Marketing Education, and others. He served as the managing director of public relations with the Federal Express Corporation before entering the Ph.D. program at Alabama. He holds a B.B.A. in accountancy from the University of Mississippi and an M.A. in marketing from the University of Alabama.  相似文献
