A method of combining survey data and Dairy Herd Improvement Association (DHIA) records to achieve low cost farm trials is presented. Farm trials and surveys of current practices and production responses are useful to identify yield gaps between expectations predicted from experimental findings and actual field results. Different management schemes can be ranked using subjective probabilities and stochastic dominance to enhance successful implementation of research findings and to increase the feedback between researchers, extension workers, and producers. A survey of current masitis control practices and expected milk yield response is the example. Combining survey results with DHIA records allowed estimating the relationship between somatic cell counts (SCC) and milk yield. Eliciting beliefs about the relationship between SCC and milk yield showed that producers agreed with predictions from the statistical model. Subjective probabilities about SCC and mastitis control practices showed that our sample of experts and producers consistently ranked the different practices but extension agents had no consensus about the the most or least effective ones. 相似文献

In this paper we compare alternative asymptotic approximations to the power of the likelihood ratio test used in covariance structure analysis for testing the fit of a model. Alternative expressions for the noncentrality parameter (ncp) lead to different approximations to the power function. It appears that for alternative covariance matrices close to the null hypothesis, the alternative ncp's lead to similar values, while for alternative covariance matrices far from Ho the different expressions for the ncp can conflict substantively. Monte Carlo evidence shows that the ncp proposed in Satorra and Saris (1985) gives the most accurate power approximations. 相似文献

This paper develops two new methods for conducting formal statistical inference in nonlinear dynamic economic models. The two methods require very little analytical tractability, relying instead on numerical simulation of the model's dynamic behaviour. Although one of the estimators is asymptotically more efficient than the other, a Monte Carlo study shows that, for a specific application, the less efficient estimator has smaller mean squared error in samples of the size typically encountered in macroeconomics. The estimator with superior small sample performance is used to estimate the parameters of a real business cycle model using observed US time-series data. 相似文献

Consolidation in the banking industry has sparked concern about the survival of small banks, particularly as it relates to the availability of credit to small businesses. However, if small banks have an advantage in processing credit information, compared to large banks, they should continue to survive in a competitive environment. We evaluate risk-adjusted commercial loan yields (gross yields less net charge-offs and the risk-free rate of return) at small and large banks for the period of 1996 through 2001. Our primary finding is that, after controlling for market concentration, cost of funds, and a variety of other factors that might influence yields, smaller banks earn greater risk-adjusted yields than larger banks. This result suggests that small banks make better choices from the available small business loans and is consistent with the notion that these banks have an information advantage in evaluating credit. 相似文献

Abstract. We experimentally investigate the effects of a mandatory increase in education on the market for professional labor services when several service qualities are assumed to exist. We show that when suppliers have insufficient incentives to offer high-quality services in a free market, an increase in mandatory education can improve the coordination of supplier decisions and increase efficiency. If suppliers voluntarily provide a sufficient quantity of high-quality services, an education constraint can have the opposite effect. In both instances, however, an increase in the mandatory level of education can be expected to reduce the price of high-quality services while increasing the price of lower service qualities. Résumé. Les auteurs ont procédé à une analyse expérimentale des conséquences qu'aurait une hausse imposée du niveau d'études sur le marché des services professionnels, si l'on suppose l'existence de plusieurs qualités de services. L'analyse démontre que lorsque les stimulants sont insuffisants pour inciter les fournisseurs à offrir des services professionnels de qualité supérieure dans un marché libre, une hausse imposée du niveau d'études peut améliorer la coordination des décisions des fournisseurs et augmenter l'efficience. Si toutefois les fournisseurs offrent de leur propre chef une quantité suffisante de services de qualité supérieure, le fait d'imposer un niveau d'études supérieur peut avoir l'effet contraire. Dans les deux cas, on peut s'attendre à ce qu'une hausse du niveau d'études obligatoire réduise le prix des services de qualité supérieure tout en augmentant le prix des services de qualité plus faible. 相似文献

Countries and their products: A cognitive structure perspective 总被引:3,自引:0,他引:3
Terence A. Shimp Saeed Samiee Thomas J. Madden 《Journal of the Academy of Marketing Science》1993,21(4):323-330
This research reports on consumers’ cognitive structures for countries and their products. In-depth personal interviews identified
respondents’ knowledge, beliefs, myths, and other relevant cognitions related to a diverse set of 11 countries and their products.
Derived cognitive dimensions were analyzed via correspondence analysis, and the 11 countries were subsequently grouped into
five sets, or cognitive categories. In addition to the empirical findings, the article introduces the concept of country equity
as a new way of thinking about global brands and discusses managerial implications related thereto.
