摘要:

This paper empirically examines the economies of size in both grain production and distribution by farm truck in Saskatchewan by using farm level data, and confirms that economies of size prevail. The examination also shows that economies of size in farm trucking reinforce the economies in production. The policy implication is such that the potential impact of an increase in rail freight rates and branch line abandonment would have a differential impact on individual producer's net income by farm size.En utilisant les données relev'ees au niveau des fermes, ce document examine d'une façon empirique les exploitations agricoles de la Saskatchewan importantes tant du point de vue de la production céréaliere que de la distribution par camionnage et confirme que ce genre d'exploitations prédomine. L'analyse montre aussi que le camionnage par gros tonnage renforce la production. L'impact potentiel d'une augmentation des tarifs ferroviaires et I'abandon des voies d'embranchement auraient un impact sur le revenu net de chaque producteur variant selon la grandeur de son exploita

摘要:

This article uses the concepts of economic surplus to assess the transfer and social cost effects of the national supply management programs for poultry products. The focus is on analytical and methodological issues and problems of identifying and quantifying these effects. It is apparent that different estimating methods and assumptions lead to considerable differences in the social cost estimates. Nonetheless, short‐run losses in allocative efficiency are relatively minor compared to the transfer effects. However, the potential long‐run losses in efficiency are substantial.Cet article utilise les concepts de surplus économiques pour évaluer les effets de transfert et de coúts sociaux dans les programmes hationaux de gestion de I'approvisionnement en volailles. Nous porterons notre attention sur les questions analytiques et méthodologiques et sur les problémes d'identification et de quantification de ces effets. II est évident que des méthoaes devaluation et des hypothéses différentes entraínent des differences considé fOlOrables dans Vestimation des coÜts sociaux. Pourtant, lespertes à court terme dues à une mauvaise distribution sont relativement minimes par rapport aux effets de transfert. Mais les pertes à long terme, pertes potentielles en efficacité

摘要:

Historical patterns of hog slaughterings are analyzed and related to a hog‐corn price ratio series using the transfer function or dynamic regression technique. This technique permits explicit tests of causal relationships and provides a systematic means for specifying distributed lag forms. It is determined that the hog‐corn price ratio series leads hog slaughterings and that there is no feedback. The estimated transfer function is analyzed in terms of its implications for the supply of hogs and its implications for the length of the hog cycle.Nous analyserons les schémas historiques de l'abattage de pores et Us mettrons en correspondence avec une série de rapportsprix du porc —prix du maïs en ulilisant lafonction de transfert ou la technique de regression dynamique. Cette technique permet de tester explicitement les relations causales et foumit un moyen systématique de spécifier les formes de retard distribué. On a determine que Vabattage de pores dépend de la série de rapports prix du pore —prix du maïs mais que I'inverse n'est pas vrai.

摘要:

Recent theoretical and empirical studies of beef cattle producers by Barros, Jarvis, Nores, Reutlinger, and Yver have focused on producers' supply response assuming cattle represent consumption goods and capital goods. To differentiate producer price response for cattle sold as consumption goods and cattle retained as capital goods requires data on herd and slaughter age‐sex structure. This has limited the range of econometric work which could be carried out in many developing countries. This study utilizes a time series of the Colombian cattle herd which was recently constructed by Rivas and Valdes and which has the necessary age‐sex and slaughter data to develop a complete system of structural equations representing the simultaneous determination of demand and supply for Colombian cattle over the 1950–1970 p
