We study convex risk measures describing the upper and lower bounds of a good deal bound, which is a subinterval of a no‐arbitrage pricing bound. We call such a convex risk measure a good deal valuation and give a set of equivalent conditions for its existence in terms of market. A good deal valuation is characterized by several equivalent properties and in particular, we see that a convex risk measure is a good deal valuation only if it is given as a risk indifference price. An application to shortfall risk measure is given. In addition, we show that the no‐free‐lunch (NFL) condition is equivalent to the existence of a relevant convex risk measure, which is a good deal valuation. The relevance turns out to be a condition for a good deal valuation to be reasonable. Further, we investigate conditions under which any good deal valuation is relevant.  相似文献

The published literature relating to the location of a business tends to support two different kinds of theories: (1) that business locations are selected to minimize costs; or (2) that decision-makers select locations because of personal preferences. This study attempts to find explanations as to why certain communities have grown faster than others, and to provide a model for the location decision of a start-up business.We find a negative correlation of two entrepreneurship measures to environmental factors that are usually considered to be desirable, i.e., health care and the environment, climate and terrain, recreation, and low crime. We find a weak correlation between community attitudes and the entrepreneurship measures. We also find a positive correlation of entrepreneurship with a high number of college graduates; a negative correlation when a high proportion of the population is over age 65.Population mobility and low unemployment are also positively correlated with the measures, but those factors seem at least as likely to be results as to be causes of business births and business growth.We believe that start-ups are vital for any community that wishes to grow, therefore the location decision of start-up businesses seems important. We propose a model of the location decision of a start-up, a model that emphasizes the individuality of the decision maker and the specific success requirements of the business. The driving force behind a start-up can be a decision-maker's desire for personal gain, a problem that begs a solution, or a solution that is looking for a problem. In some cases, the reason for starting a business will dictate its location. In other cases, success requirements of the business will dominate. We believe that researchers can gain a true understanding of the location decision only by considering both the preference of the decision-maker and the requirements of the specific business.  相似文献

We consider the problem where rankings, provided for instance by a group of evaluators, have to be combined into a common group ranking. In such a context, Arrow and Raynaud suggested that the compromise ranking should be a prudent order. In general, a prudent order is not unique. That is why, we propose to manage this possible multiplicity of compromise solutions by computing robust conclusions. This allows for a progressive refinement of the decision model and supports the group to eventually select one group ranking. The approach is illustrated on a problem where a group of junior researchers has to agree on a ranking of research domains.  相似文献

We propose a methodology to draw a representative sample from a population with a small fraction of potential customers for a certain product or a service. The objective is to increase the expected number of potential customers in a sample of fixed size representing the whole population. The method also provides a useful way of incorporating subjective judgement and uncertainty into the sampling plan. This approach has produced very satisfactory results for rare event problems in a number of telecommunications applications.  相似文献

Marketers have traditionally evaluated products and practices on the basis of whether something could be sold. It is also important to evaluate products and practices from a societal perspective, “Should a product be sold?” The first idea reflects a managerial orientation and what must be done to sell a product; the second idea reflects a societal orientation and the impact of selling a product. In relation to the second idea, the societal marketing concept was introduced in 1972. There has been little advancement in our understanding of a societal orientation since that time. The current study presents a conceptualization of a societal orientation based on a review of literature and qualitative interviews. The construct was conceptualized as “attention to the long-term well-being of individuals and society at large by enhancing positive impacts from and reducing negative effects associated with production and consumption of a product.” Five domains comprising a societal orientation are proposed: physical consequences, psychological well-being, social relationships, economic contribution, and environmental consciousness.  相似文献

Competition in Markets and Competition for Markets   总被引:1,自引:1,他引:1  
This paper builds on a distinction that is sometimes made between competition in a market and competition for a market. Competition for a market refers to the struggle to create a new market, or to erect a new standard, and it is usually associated with the process of innovation that brings new displacing technologies to market. Competition in a market is the conventional view of competition, and concentrates on the actions of incumbents and imitative entrants in well-established markets. The paper reviews some of the issues that competition for markets raises for anti-trust policy makers, and then asks whether competition for a market is a perfect substitute for competition in a market.  相似文献

Two studies were conducted to assess separateness-connectedness (SC) as a new message variable and as a new individual difference variable in advertising. Study I began the process of developing a Separateness-Connectedness scale based on a sample of 140 college students (97 Westerners and 43 non-Westerners, 81 males and 59 females) attending a midwestern university. The 9-item, 2-factor scale revealed good reliability and construct validity. The structure of the overall model was then successfully tested on a new sample by confirmatory factor analysis. In Study II an experiment assessed whether the separateness/connectedness self-schema would moderate the effect of using either a connected or a separated advertising appeal on consumers' attitude toward the ad. As predicted, a significant interaction effect was found. The results revealed that individuals with a separate self-schema preferred a separated advertising theme, and individuals with a connected self-schema preferred a connected advertising theme. Implications for advertising managers, the studies' limitations, and future research directions are also discussed. © 1997 John Wiley & Sons, Inc.  相似文献

Online customer reviews have been shown to have a powerful impact on the sales of a given product or service. However, the qualities of a ‘credible’ online customer review are still subject to debate. Existing research has highlighted the potential influence of a range of factors on the credibility of an online customer review, but relies heavily on quantitative methods and a ‘top down’ approach. In turn, this can reduce our understanding of the influence of these factors into merely discerning whether one pre-determined factor is more influential than another is. This paper adopted a ‘bottom up’ thematic analysis of individual qualitative interviews with a purposeful sample of consumers who regularly utilised online customer reviews. The findings uncovered a range of factors that influenced the credibility of an online customer review that were attached to a reader’s personal experience and to the content of a specific review, and inferred the existence of a reciprocal relationship between the constructs of review helpfulness and review credibility.  相似文献

Using a simple overlapping generations framework, calibrated to four Southern European countries, we analyze the relationship between tax evasion, determined endogenously, and financial repression. We show that higher degree of tax evasion within a country, resulting from a higher level of corruption and a lower penalty rate, yields higher degrees of financial repression as a social optimum. However, a higher degree of tax evasion, due to a lower tax rate, reduces the severity of the financial restriction.  相似文献

We set up a model to investigate the strategic aspect of a firm's incentive to collaborate in cost-reducing R&D with either a local or a foreign partner. We argue that collaboration with a foreign firm is preferred to collaboration with a local firm if the extra profits generated by a foreign collaboration exceed the additional cost of coordinating collaboration across national borders. We show that foreign collaboration is more likely the bigger the home market size of the foreign firm and, given certain conditions, the higher the international trade cost. We also show that whenever a foreign collaboration arises in equilibrium, it is efficient (i.e., world-welfare-maximising) and that there are cases where (a) a foreign collaboration would be efficient but a local collaboration emerges in equilibrium, and (b) an efficient foreign collaboration emerges in equilibrium, but one of the countries would prefer a local collaboration. We briefly consider the policy implications of these findings.  相似文献

正义感是人类以实现正义为目的的一种美好情感,是人的一种最基本的道德情操。一个以正义感调节的社会,人民幸福,社会稳定有序。和谐社会是一个制度正义的社会。制度正义既以正义感为前提,又以正义感为当然表征。因此,和谐社会亦是一个充满正义感的社会。在当前,正义感的培养显得格外重要和紧迫。对于道德教育来说,这既是挑战,又是机遇。  相似文献

Although integrated marketing communication (IMC) has progressed towards mid-range maturity level, its full-scale adoption has been impeded by a lack of consensus on its defining constructs. The purpose of this study is to move from abstraction to define the construct of strategic integration (SI) and develop this into a management tool, thus making an important contribution to both the theory and practice of IMC. Drawing from both IMC and strategic management literature, the construct of SI is operationalised into a number of key factors and a well-cited management model, Fuchs' ‘integration valuator’ is explored as the starting point of a measurement tool for IMC. To do this, a Delphi study invites the scrutiny of an expert panel of world-leading IMC researchers and practitioners. The panel validated the model construction process, redefined overarching constructs and key factors with a high degree of consensus, supported a process measure, suggested a weighted evaluation measure and recognised the importance of developing such a measure. They delivered clear and consistent imperatives guiding model development. The result is a measure of SI that evaluates organisational proficiency and diagnoses the integration of IMC campaigns. It also advances theory by providing a better understanding of the construct of SI.  相似文献

An employer asked to provide a reference for a former or departing employee is confronted with a number of complex legal and ethical concerns. The issue of references is always controversial, involving a balance of employers' fears of legal liability, interests in providing relevant information to prospective employers, and concerns for fairness to former employees. Recently this topic has been the focus of new attention as the result of a court decision holding a former employer legally liable for wrongs committed by a former employee in a new job. In that case, the former employer had provided a positive reference while neglecting to note certain negative aspects of the former employee'sperformance. This paper addresses legal and ethical aspects of the reference dilemma and incorporates responses of human resource professionals to the question of ethical reference policies and practices.  相似文献

This paper reports on the use of a Group Support System (GSS) to explore at a micro level some of the processes manifested when a group is negotiating strategy—processes of social and psychological negotiation. It is based on data from a series of interventions with senior management teams of three operating companies comprising a multi-national organization, and with a joint meeting subsequently involving all of the previous participants. The meetings were concerned with negotiating a new strategy for the global organization. The research involved the analysis of detailed time series data logs that exist as a result of using a GSS that is a reflection of cognitive theory.  相似文献

赌场业是一种兼有服务业和金融业双重性质的产业.作为服务业,赌场的豪华程度以及与之相联系的服务产品质量的差异对于赌客是有意义的,在价格一律的条件下激励赌客由低档小赌场向高档大赌场流动.作为金融业,赌博价格是一个投资(赌博)回报率的概念,它无法作为反映赌场豪华程度和服务质量价差的价格杠杆作用.这导致了赌场业的有质差无价差的现象,进而赋予了豪华大赌场较之简陋小赌场的竞争优势,进而导致了在赌场建设上的豪华竞赛以及与此竞赛相联系的资源浪费和市场失败.文章研究和分析了由赌业的两栖性所导致和推动的赌场间豪华竞赛的经济动因和机理,进一步指出澳门赌业的发展,不能自由放任.  相似文献

Fear of missing out (FOMO) is an emerging topic in consumer psychology. However, the theoretical foundations of FOMO are underdeveloped and extant FOMO scales confine the construct to the context of social media. Without a theoretical foundation and a new FOMO scale, the future development of research on this promising phenomenon is limited. This article provides a new conceptualization of FOMO and a new FOMO scale. Using self-concept theory, the authors propose that FOMO is an emotional response to perceived psychological threats to one's self-concept. Because the self-concept involves a private and a public self, FOMO involves two dimensions: a personal FOMO and a social FOMO. Accordingly, a new scale was developed. The results of four studies support the validity and reliability of the two-dimensional scale. This new conceptualization and scale will enable consumer researchers to examine FOMO in a broader set of contexts, test the relationship between FOMO and related constructs, and develop a nomological network around the construct.  相似文献

Marketing research has a limited understanding about the effects arising from emotional shifts (i.e., the transition from one emotion to another) during the same advertising message. This paper sheds light on this topic through two studies. Study 1 examines whether an advertising message that features a negative-to-positive emotional shift (i.e., a shift from a negative to a positive emotion) generates greater recall of an advertised brand than an advertising message with a neutral-to-positive emotional shift (i.e., a shift from a neutral to a positive emotion) or one with no emotional shift. Study 2 examines whether an advertising message that simulates a buyer-seller encounter—with the seller reproducing a negative-to-positive emotional shift via facial expressions—generates a greater recall of the advertised content than an identical advertisement with no emotional shift. Results confirm that a negative-to-positive shift facilitates the recall of both the brand and the advertised information.  相似文献

In the market of consumer electronics, firms often limit their product supply to create a scarcity effect to entice consumers to buy their product. However, the outcome of such a strategy is not always desirable. In this study, we propose the product configuration level as a contingent variable that works with the supply level to affect the outcome of a supply limitation strategy. With a vignette-based experiment, we find that for a product with a superior configuration, consumers' purchase intention is boosted only if the supply is very limited. For a product with an inferior configuration, however, the supply limitation strategy does not work at any supply level. Therefore, the supply limitation strategy works only for a superior product configuration and at a fine-tuned supply level.  相似文献
