Framing effects on retail store choice decisions were investigated in four experiments. Subjects preferred the store that guaranteed (a sure option) good prices (experiment 1), product availability (experiment 2), or a rebate (experiment 3) when consequences were framed in terms of gains; subjects preferred the risky option when consequences were framed in terms of losses. Consistent with fuzzy-trace theory, framing effects were reduced when the expected values of options were disparate in a direction that disfavored sure gain or probabilistic loss options (experiment 2) and when the perceived costs of committing a judgmental error were high (experiment 3). Experiment 4 shows that the moderating effects of disparate expected values and costs of judgment errors generalize to within-subject designs.  相似文献

The study in this article involved the investigation of 15 carrier selection variables over three dimensions by three groups with high involvement in the purchasing decision—traffic managers, sales representatives, and sales managers. The primary focus of the study was the identification of significant differences in the assessment of importance of the technical abilities of a carrier, the service orientation of a carrier and the image of a carrier as perceived by sales managers and sales representatives representing the selling systems, and traffic managers representing the buying systems.  相似文献

Conclusions Unlike McKenzie and Tullock, we do not know how personsshould treat their bodily organs or what is an ideal exit. That depends upon their utility goals, which are defined in output terms specific to the decision maker. We contend that the body is an input into the utility production process, and therefore, as with any input, it must be maintained and repaired at a level consistent with the output goals for maximization of utility. Thus, from this framework, it is quite consistent for a person to die with healthy organs without any thought of belief in reincarnation or the desire to bequeath one's bodily organs to others, or religious values. Self interest is all that must prevail.Also, the fact that there are interrelationships between the organs in the system, and at points these relationships take on fixed factor characteristics such that reduced levels of operation in one organ can create disorientation or coma or damage to other organs, means that the body cannot die as M-T suggest. Zero capacity for all organs at death is a technical impossibility as well as being inconsistent with the output goals of utility maximizers.  相似文献

Frictions, Heterogeneity and Optimality in Mortgage Modeling   总被引:1,自引:0,他引:1  
The purpose of this article is to provide a unified framework for incorporating frictions into a theoretical options-pricing model (OPM) for mortgages. This article presents formulation for a frictions-adjustable mortgage model that integrates borrower heterogeneity while simultaneously preserving prepayment and default financial decisions. Our model demonstrates the flexibility of the OPM by simulating separate and concurrent effects of three categories of frictions on the mortgage and mortgage components. Researchers can use our example formulation to determine the effects of specific borrower characteristics on mortgage values without destroying the options theoretic framework.  相似文献

E-Finance: An Introduction   总被引:1,自引:0,他引:1  
E-finance is defined as “The provision of financial services and markets using electronic communication and computation”. In this paper we outline research issues related to e-finance that we believe set the stage for further work in this field. Three areas are focused on. These are the use of electronic payments systems, the operations of financial services firms and the operation of financial markets. A number of research issues are raised. For example, is the widespread use of paper-based checks efficient? Will the financial services industry be fundamentally changed by the advent of the Internet? Why have there been such large differences in changes to market microstructure across different financial markets?  相似文献

Although there are many projects, mainly supported by international donors, demonstrating that the Internet can be supplied to rural areas in developing countries, the real objective is to make these projects sustainable on a commercial basis. Among other things, this type of sustainability will require a project with unusually low costs of Internet delivery to poor, isolated users. In this paper we have examined a case from India, which uses a unique combination of low-cost indigenous technology and a low-cost model of delivery that exploits the ability of the informal sector to respond and adapt to local needs. This model, we feel, may serve as an example, to other developing countries seeking to bridge the global Digital Divide.  相似文献

This paper investigates the impact of divergent consumer confidence on option prices. To model this, we assume that consumers disagree on the expected growth rate of aggregate consumption. With other conditions unchanged in the discrete-time Black–Scholes option-pricing model, we show that the representative consumer will have declining relative risk aversion instead of the assumed constant relative risk aversion. In this case all options will be underpriced by the Black–Scholes model under the assumption of bivariate lognormality. This revised version was published online in June 2006 with corrections to the Cover Date.  相似文献

Measures developed for the analysis of corporate diversification have become fundamental to a broad range of strategy research. This paper examines the content validity of the two most widely used continuous measures of related diversification—the related component of the entropy index and the concentric index—and raises fundamental questions about their validity as indicators of portfolio relatedness. These questions are not driven by the use of SIC data for estimation of the indexes; they involve validity problems intrinsic to the construction of the measures. The related component of entropy and the concentric index are sensitive to features of corporate portfolio composition that may not be directly linked to portfolio relatedness. These sensitivities can create important ambiguities in strategy research. Copyright © 2002 John Wiley & Sons, Ltd.  相似文献
