赌场豪华竞赛:产业两栖性制造的市场失败

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.     

A Bayesian survey technique for rare subjects

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.     

Control the risks of high-stakes litigation

A litigation crisis can be not only a costly jolt to a company's financial health but a disruptive force to company personnel and markets. Here is a blueprint for formulating a contingency plan for dealing with such a crisis.     

正义感：构建和谐社会的重要因素

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。     

Negotiation in Strategy Making Teams: Group Support Systems and the Process of Cognitive Change

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.     

How price increases affect future purchases: The role of mental budgeting,income, and framing

This article suggests that mental budgeting processes provide afurther understanding of how and to what degree price increases negatively affect a customer's future purchase behavior in a particular category of expenses. Furthermore, the authors analyze how customer income and different price presentation tactics alter this reaction. Results of two experimental studies using both students and non‐students show that customer income attenuates the negative effect of a price increase on the likelihood of a future purchase in a particular expense category. As an underlying mechanism, the influence of customer income on future purchase behavior is partially mediated by the degree to which customers engage in mental budgeting. Moreover, mental budgeting strengthens the negative effect of a price increase on a future purchase in the same category of expenses, whereas it does not alter the effect of a price increase on a future purchase in another category. Finally, the framing of a price increase as a percentage versus in absolute terms leads to a lower likelihood of a future category purchase. © 2009 Wiley Periodicals, Inc.     

CONVEX RISK MEASURES FOR GOOD DEAL BOUNDS

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.     

Bond Market Structure in the Presence of Marked Point Processes

We investigate the term structure of zero coupon bonds when interest rates are driven by a general marked point process as well as by a Wiener process. Developing a theory that allows for measure–valued trading portfolios, we study existence and uniqueness of a martingale measure. We also study completeness and its relation to the uniqueness of a martingale measure. For the case of a finite jump spectrum we give a fairly general completeness result and for a Wiener–Poisson model we prove the existence of a time–independent set of basic bonds. We also give sufficient conditions for the existence of an affine term structure.     

Interdependent preferential trade agreement memberships: An empirical analysis

The establishment of a new preferential trade agreement (PTA) or the expansion of an existing one alters the incentives of non-members to participate in a PTA. This can lead to a domino effect whereby non-members join an existing PTA. Or it can lead a pair of countries to establish a new PTA. We examine the determinants of why a pair of countries enters a bilateral PTA. Our emphasis is on (a) the impact of pre-existing PTAs and (b) whether this impact is larger when the members of pre-existing PTAs are on average geographically close to the pair of countries. Using data for 145 countries during 1955-2005, we find evidence that pre-existing PTAs increase the probability that a country-pair will enter a bilateral PTA and that this effect diminishes with distance. The analysis makes use of techniques drawn from spatial econometrics.     

Applying yield management pricing to your service business

Yield management pricing is a broad term that describes how a service provider can secure higher revenues from its relatively fixed capacity. There are several major advantages associated with the use of yield management pricing. Through use of yield management, a firm can better compete against a low-cost provider. Yield management pricing is an effective mechanism to allocate a service provider's relatively fixed capacity, and is also a more efficient alternative to providing discounts on a much broader scale. This article discusses how a service provider can develop and maintain a yield management system through completion of eight interrelated steps.     

Firms’ export decisions—fixed trade costs and the size of the export market

This article presents a model of international trade under monopolistic competition. In the increasing returns sector firms face fixed, in addition to variable, trade costs, and both exporters and non-exporters may coexist. Exporters benefit from access to large foreign markets, thus a small country has a higher share of exporting firms than a large one. In contrast to standard models, the increasing returns sector will be more open in a small country than in a large one, and a small country may be a net exporter of such commodities, despite the disadvantage of a smaller home market.     

Making an exciting brand big: Brand personality,logo size and brand evaluation

This research examines how brand personality (excitement) and logo size used in product design (big versus small) interacts in affecting consumer brand evaluation. We first demonstrate that combining a big logo and a high-excitement brand (versus a small logo combined with a high-excitement brand) leads to high processing fluency, further resulting in more favourable brand evaluation (Study 1). We then determine the consumption situation as a moderator of such an interaction effect: the influence of the big logo and high-excitement-brand combination on brand evaluation is significantly weakened in a private consumption situation (a T-shirt worn at home) compared to a public consumption situation (a T-shirt worn outside, Study 2a), and becomes insignificant for a private product category (slippers, Study 2b).     

The effect of product positioning in a comparison table on consumers’ evaluation of a sponsor

This paper examines the effect on consumers’ perceptions resulting from the positioning of a sponsor in relation to a competitor or competitors in a comparison table of a print advertisement. We hypothesize when a sponsor places its product in the right-hand panel and the competitor’s product in the left-hand panel, respondents will react with a favorable evaluation for the sponsor as a result of two primary forces. The first is a general preference for an object positioned on the right as opposed to an object positioned on the left. The second is a vastly prevalent left-to-right reading habit. The prevalent left-to-right reading habit can lead consumers to subconsciously perceive this layout as a positive comparative advertisement, and the reversed placement is perceived as a negative comparative advertisement. We confirmed the hypothesis with three laboratory experiments.     

The Use of Telephone Directories as a Sample Frame: Patterns of Bias Revisited

A study was undertaken to reassess the utility of using telephone directories as a sample frame. A survey research unit within the Genesee County Health Department of Flint, Michigan, randomly sampled 1,031 households from the city of Flint using a complete listing of dwellings within the city as a universe. In addition to the normal interview schedule used, households were given a supplemental questionnaire on telephone service. The adult household respondent was asked if the household had a telephone and, if not, why. If the household had a telephone the respondent was asked if the number was listed in a phone directory or not. If the phone was unlisted, the respondent was asked why. The results were quite similar to those found by past research. There were a number of statistically dependent relationships found between whether or not households had listed or unlisted phones and various characteristics of household heads as well as other household features. It is concluded that using a telephone directory as a sample frame may lead to a significant sampling bias. Telephone sampling can still be a useful marketing tool if random digit dialing is used. This latter suggestion is briefly discussed.     

Technological advantage,alliances with customers,local knowledge and competitor identification

Research typically studies competitor identification in stable markets and seldom considers possible antecedents in a dynamic context. To address this situation, this study combines a relational view, a capability-based approach, and a managerial cognition view to predict competitor identification. The hypotheses concern how a firm's customer ties, technological advantage, their interaction, and top manager's local knowledge influence competitor identification. Using a sample of 1348 firms across manufacturing and servicing sectors in China, we find that strong customer ties have a positive impact on competitor identification, firm-specific technological advantage has a negative impact, and the interaction of the two positively relates to competitor identification as does having greater local knowledge. These results suggest that a relational view, a capability-based view and a managerial cognition view complement one another in determining competitor identification in a dynamic environment.

Place the good after the bad: effects of emotional shifts on consumer memory

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.     

How to protect your premium product from low-price competitors: Price,quality, or portfolio adjustment?

In a game-theoretic framework, I analyze how a brand manufacturer can thwart new entrants into its market. Three strategic options are considered, a price adjustment of the premium product, a quality adjustment of the premium product and a portfolio adjustment of adding a fighter brand. In a basic setup, I show that the incumbent's best response to entry is to choose a portfolio adjustment. If, however, the incumbent is uncertain about whether the rival firm will enter the market, a price adjustment of the premium product might be the better alternative if launching the fighter brand is associated with costs. Moreover, if technological progress improves the efficiency of product development, a combined quality and portfolio adjustment might be the best alternative for the incumbent.     

Trade liberalization and strategic outsourcing

This paper develops a model of strategic outsourcing. With trade liberalization in the intermediate-product market, a domestic firm may choose to purchase a key intermediate good from a more efficient foreign producer, who also competes with the domestic firm for a final good. This has a strategic effect on competition. Unlike the outsourcing motivated by cost saving, the strategic outsourcing has a collusive effect that could raise the prices of both intermediate and final goods. Trade liberalization in the intermediate-good market has a very different effect compared with trade liberalization in the final-good market.     

The Effect of Franchisors' Communication, Service Assistance, and Competitive Advantage on Franchisees' Intentions to Remain in the Franchise System

This study developed and empirically tested a model examining the antecedents of franchisees' overall satisfaction and intention to remain in a franchise system. Based on a sample from a convenient store franchise system in Taiwan, the results showed that communication is very important in reinforcing franchisees' trust and overall satisfaction with the franchise system. The results also showed that competitive advantage of a franchise system is the basis for a franchisee's overall satisfaction and intention to remain in a franchise system. However, satisfaction of a franchisor's service assistance did not have direct impact on a franchisee's overall satisfaction toward the franchise system.
