Consumers face considerable frustration when purchasing structurally and/or semantically complex high-involvement products online. Reliance on computer-mediated communications for their information needs may result in functional and emotional frustration from information overload and lack of personal trust. This paper proposes a responsive real-time information system as a proxy for a perceptive sales representative who assesses customer needs based on information exchanges and then offers appropriate responses. By tracking and analyzing a consumer's online activity, vendors can offer information relevant to the consumer's real-time needs, facilitating their purchase process. In essence, this is a real-time value co-creation process based on the consumer offering cues to vendors through their key strokes and mouse click activity. This allows for differentiated information offerings for inexperienced and more experienced consumers, creating value by dynamic information serving. Where appropriate value is created, consumers will experience less frustration and continue online, rather than possibly moving offline or to alternative vendors. In examining the bases of consumer information needs in complex purchases, this paper identifies the data required to enable a responsive dialog between vendors and consumers. 相似文献

We study the asymptotic behavior of distribution densities arising in stock price models with stochastic volatility. The main objects of our interest in the present paper are the density of time averages of a geometric Brownian motion and the density of the stock price process in the Hull–White model. We find explicit formulas for leading terms in asymptotic expansions of these densities and give error estimates. As an application of our results, sharp asymptotic formulas for the price of an Asian option are obtained. 相似文献

This article presents evidence that the European Monetary System (EMS) bands for the Italian lira and the pound sterling were not credible for most of the period 1990–1992, and especially during the week prior to their withdrawal from the EMS system. Using a simple test, developed by Svensson, domestic interest rates for both Italy and the United Kingdom have been found to be mostly outside the rate-of-return bands implied by the official arrangements of the EMS target zone system. Furthermore, comparing implied forward rates for various maturities with the official EMS bands of both currencies, we again found that the followed monetary policies in both countries were not in general consistent with those needed to maintain an orderly functioning of the (EMS) system. The Svensson test can further be used as an indicator of potential speculative attacks on an EMS currency, and, in turn, as a signal of an emerging need to adjust the corresponding country's monetary policy. 相似文献

We compare the performance and risk of a sample of 181 large banks from 15 European countries over the 1999–2004 period and evaluate the impact of alternative ownership models, together with the degree of ownership concentration, on their profitability, cost efficiency and risk. Three main results emerge. First, after controlling for bank characteristics, country and time effects, mutual banks and government-owned banks exhibit a lower profitability than privately owned banks, in spite of their lower costs. Second, public sector banks have poorer loan quality and higher insolvency risk than other types of banks while mutual banks have better loan quality and lower asset risk than both private and public sector banks. Finally, while ownership concentration does not significantly affect a bank’s profitability, a higher ownership concentration is associated with better loan quality, lower asset risk and lower insolvency risk. These differences, along with differences in asset composition and funding mix, indicate a different financial intermediation model for the different ownership forms. 相似文献

This study investigates the considerations that might be made by managers when choosing between mutually exclusive stakeholder expectations and reaching and engaging in a dialogue with them. In addition, the study also examines if there are systematic differences across countries (Italy and the US) in the decision to address the concerns of various stakeholder groups. Data was collected from 244 managers and 72 companies simultaneously in two different national business contexts, Italy and the US. The results of the study provide some evidence that managerial perception of three stakeholder group characteristics – power, legitimacy, and urgency – form a parsimonious group of variables that explain the process of stakeholder prioritization. However, only limited support was found for the relationship between salience accorded to a stakeholder group and engagement efforts directed toward the group. The results of the study also show that the managerial decision as to which of the stakeholder groups’ demands to address will be influenced by society-specific expectations. The significance of this study lies in investigating the stakeholder prioritization and engagement process, as it is being practiced, which, one could argue, would help in developing guidelines for effective stakeholder management that stands a realistic chance of being adapted and followed. 相似文献

Trade policy barriers and high transaction costs hinder developing countries from taking the full advantages of the global trading system. In order to help developing countries overcome the problem, the World Trade Organization (WTO) launched the Aid for Trade (AFT) initiatives in its Ministerial Conference held in Hong Kong in 2005. We examine the effects of AFT inflows on bilateral trade costs facing 133 developing countries while accounting for differences in their location on the contours of various measures of institutional quality. Our results from the estimation of a mixed effects (random-intercept and random-coefficient) model indicate that institutional quality significantly affects the extent to which AFT reduces bilateral trade costs. An important policy implication of our findings is that an economically robust and sustainable reduction in bilateral trade costs facing developing countries requires the presence of both promulgated and effectively functioning institutions such as regulatory power and the rule of law. 相似文献

AbstractObjective: To develop an economic model to evaluate changes in healthcare costs driven by restricting usage of branded tyrosine kinase inhibitors (TKIs) through substitution with generic imatinib among chronic myeloid leukemia (CML) patients in a typical Oncology Care Model (OCM) practice, and examine the impact on Performance-Based Payment (PBP) eligibility.Methods: An Excel-based economic model of an OCM practice with 1,000 cancer patients during a 6-month episode of care was developed. Cancer types and proportions of patients treated in the practice were estimated from an OCM report. All-cause healthcare costs were obtained from published literature. It was assumed that if a practice restricts usage of branded TKIs for newly-diagnosed CML patients, 80% of the market share of branded imatinib and 50% of the market shares of 2nd-gen TKIs would shift to generic imatinib. Among established TKI-treated patients, it was assumed that 80% of the market share of branded imatinib and no patients treated with 2nd-gen TKIs would shift to the generic.Results: Four CML patients were estimated for a 1,000-cancer patient OCM practice with a total baseline healthcare cost of $51,345,812 during a 6-month episode. If the practice restricts usage of branded TKIs, the shift from 2nd-gen TKIs to generic imatinib would reduce costs by $12,970, while shifting from branded to generic imatinib lowers costs by $25,250 during a 6-month episode. Minimum reductions of $3,013,832 in a one-sided risk model and $2,372,010 in a two-sided risk model are required for PBP eligibility; the shift from 2nd-gen TKIs to generic imatinib would account for 0.4% and 0.5% of the savings required for a PBP, respectively.Conclusions: This analysis indicates that the potential cost reduction associated with restricting branded TKI usage among CML patients in an OCM setting will represent only a small proportion of the cost reduction needed for PBP eligibility. 相似文献

Brand crises endanger companies. Social media are a key platform where stakeholders elaborate and react to crises. This research explores whether social media audience and traditional mass media audience react differently to a brand crisis in terms of their (1) attitude towards the brand and (2) word-of-mouth (WOM). As to the brand attitude, we argue that stakeholders mainly exposed to the brand crisis via social media have a more negative reaction towards the brand compared to those who are principally exposed via traditional media. As to the behaviour, we posit that social media exposure intensifies WOM. By analysing the Barilla crisis, the findings suggest that the social media act as ‘multipliers’ of the reaction of stakeholders to a brand crisis. 相似文献

There are two competing definitions of economics. One, exemplified in Etzioni's work, stipulates that economics is the study of one kind of ends, the pursuit of material benefits (welfare). This definition entails that material ends are incommensurable with moral ends. The other, expressed in Becker's work, registers that economics is the analysis of one aspect of all ends, optimization. This definition implies that material and moral ends are commensurable. The paper finds that each definition has its own shortcomings. The paper outlines an alternative view, illustrated by the difference between gifts and grants, which promises to supplant the shortcomings of each definition. 相似文献
