“…A differentiated product, such as a broodmare, is demanded by breeders because of the particular characteristics it possesses. Either case, utility or profit maximization, yields a hedonic price function that expresses price as a function of the quality and quantity of characteristics associated with the product (Schroeder, Espinosa, & Goodwin, 1992).…”

Thoroughbred broodmares are the primary input in the foal production process. Breeders need to make informed broodmare investment decisions, since substantial financial and genetic risks are associated with overvaluing a broodmare's productive capacity. Each broodmare represents a unique combination of breeding, racing, and genetic characteristics. This study estimates the marginal values of broodmare characteristics. Results identify large price differentials for broodmares that have won or produced graded stakes race winners. The analysis provides information for marketing, accounting and management decisions.

The study was conducted to estimate relative economic values (REVs) of survival, body weight, growth rate, reproduction, docility and food intake. Data were obtained from records of grasscutters (Thryonomys swinderianus) kept at the grasscutter section of the Department of Animal Science Education, University of Education, Winneba, Ghana. Average values of production inputs and outputs parameters were computed from records of 502 kids born between 2006 and 2010. Relative economic values of traits were computed by using computer models in Microsoft Excel spreadsheet of Windows 2007. When feed intake was included in the breeding objective and economic evaluation was based on genetic standard deviation, mature body weight emerged as the most important trait. Ranking order of traits was body weight > survival > reproduction > growth rate > feed intake > docility. The ranking order was maintained when feed cost was set to zero. The use of coefficient of variation to estimate REVs changed the ranking order of traits: Growth rate > reproduction > docility > survival > body weight > feed intake. It was concluded that post-weaning growth rate, litter size at weaning and docility should be selected to be included in the breeding objective of grasscutter breeding programmes in Ghana.

“…Neoclassical input characteristic models commonly have been used to examine demands for input characteristics of commodities such as cotton (Ethridge and Neeper 1987;Bowman and Ethridge 1992), tomatoes (Jordan et al 1985), rice (Brorsen et al 1990), purebred dairy bulls (Schroeder et al 1992), hogs (Walburger and Foster 1994), and wheat (Barkley and Porter 1996).…”

Diffusion patterns of all major bread wheat varieties released in western Canada over the period 1950–92 are analyzed. Agronomic, quality and disease attributes of each variety are examined to explain diffusion patterns. It is found that the pattern of diffusion is affected most by yield, days to maturity, test weight, lodging and bunt. The relative importance of these attributes varies somewhat by agroclimatic region within the prairie provinces. Nous avons analysé le tableau de répartition territorial de toutes les grandes variétés de bléà pain mises au commerce dans l'ouest du Canada entre 1950 et 1992. Nous en avons également cherché l'explication d'après les caractères agronomiques, qualitatifs et sanitaires de chaque variété. Le rendement grainier, la précocité de maturation, le poids à l'hectolitre et la résistance à la verse et à la carie se sont révélés les déterminants principaux de la diffusion variétale, bien que leur importance relative ait varié quelque peu selon les différentes zones agroclimatiques des provinces des Prairies.
