The advertising budget allocation decision has been recognized as a critical decision that should receive logical, scientific determination. However, actual decision-making practice indicates that marketers typically use qualitative, non-scientific methods when setting advertising budgets. This article discusses the reasons for this practice by focusing on the properties of qualitative models which make them attractive to practitioners and the properties of quantitative models which make them unattractive. To assist in this analysis, a taxonomy for the classification of various qualitative and quantitative budget models is constructed, the emphasis of which is on the perceived usefulness of a budget model to practitioners.  相似文献

The authors conducted a painstaking review of widely used economics textbooks to determine if or how issues relating to race and gender are treated. In doing so, the authors also shed light on the nature of the treatment of these issues.  相似文献

Summary The Neyman-Pearson Lemma describes a test for two simple hypotheses that, for a given sample size, is most powerful for its level. It is usually implemented by choosing the smallest sample size that achieves a prespecified power for a fixed level. The Lemma does not describe how to select either the level or the power of the test. In the usual Wald decision-theoretic structure there exists a sampling cost function, an initial prior over the hypothesis space and various payoffs to right/wrong hypothesis selections. The optimal Wald test is a Bayes decision rule that maximizes the expected payoff net of sampling costs. This paper shows that the Wald-optimal test and the Neyman-Pearson test can be the same and how the Neyman-Pearson test, with fixed level and power, can be viewed as a Wald test subject to restrictions on the payoff vector, cost function and prior distribution.  相似文献

Community views of ecotourism   总被引:2,自引:0,他引:2  
Ecotourism can be an incentive for conservation, especially when it triggers positive economic change. Yet it introduces many changes to communities:positive and negative, social and economic. The full range of change is seldom evaluated in direct relation to conservation at the local level. In this study of three Amazon ecotourism projects, local leaders discussed changes from ecotourism in their communities. Economic benefits were mentioned, but so were new restrictions on time, decreased reciprocity, and social conflict. Other changes included heightened self-esteem and greater community organization. Such shifts should be considered in relation to conservation as they affect the stability of local institutions and the prospects for long-term collective action for resource management.  相似文献

Optimism about the increased engagement of women in information technology employment has been informed, in part, by essentialist ideas about the suitability for women of emerging jobs combining technical with interpersonal, artistic or other 'non-technical' skills. Drawing on evidence from Australia, we highlight limitations to this brand of optimism, questioning the potential for women in mixed-skill jobs in computing and multimedia organisations.  相似文献

We examine the usefulness and credibility of analyst recommendations by focusing on their behavior surrounding tender offer announcements. For our 1998–2001 sample, we find analysts did not identify takeover targets through their recommendations nor did they distinguish between wealth‐increasing and wealth‐decreasing tender offers. We find some evidence of conflicts of interest in analyst recommendations, but it is confined to the 1999–2000 dot‐com period. However, the long‐run performance following recommendations suggests that these conflicts have little ultimate cost to investors.  相似文献
