This study is a cross‐cultural examination of the ideal self‐image of women in terms of health and beauty. The match‐up between two advertising beauty types (possible advertising presenters) and female consumers' ideal health and beauty images in terms of wanting to look like a specific model were tested with 750 female respondents from five European cities. The respondents also identified the ideal eye and hair colors for health and beauty. This quantitative study revealed cross‐cultural variation in ideal self‐image in terms of healthy and beautiful beauty types. International advertisers need to understand the important, contemporary, cultural characteristics of an ideal beauty type in terms of healthy or beautiful before developing standardized advertising communicating such appeals. © 2006 Wiley Periodicals, Inc.  相似文献

We use a model of mean-shifting investment technologies to study the relationship between market structure, risk taking and social welfare in lending markets. Introduction of loan market competition is shown to reduce lending rates and to generate higher investments without increasing the equilibrium bankruptcy risk of borrowers. Hence, there need not be a tradeoff between lending market competition and financial fragility. Such a tradeoff may not emerge either when banks compete by conditioning interest rates on investment volumes irrespectively of whether credit rationing takes place or not.  相似文献

We design a compound real options model, which determines the timing of takeovers and characterizes the distribution of the associated surplus. We delineate a relation between the bargaining power of the acquiring firm and the takeover incentives. The takeover threshold is decreasing as a function of the expected primary takeover gain and the embedded divestment gain. Decreased implementation uncertainty stimulates takeover activity. This uncertainty concerns the delay until either primary takeover synergies or subsequent divestment gains are realized. We demonstrate how the relation between volatility and takeover timing depends on the functional form of the profit flow with implementation uncertainty.Financial support from the Foundation for the Promotion of the Actuarial Profession and the Finnish Insurance Society to Luis H.

We analyze how different degrees of privacy protection affect industry profits, consumer welfare, and total welfare in a model with switching costs. Firms earn higher profits under weak privacy protection compared with strong or no privacy protection. The relationship between the degree of privacy protection and equilibrium profits is not monotonic. Consumer surplus and total welfare increase with the degree of privacy protection unless firms recognize consumer‐specific switching costs. In that case, pricing conditional on switching costs has favorable implications for consumer surplus and total welfare.  相似文献

We analyse the effect of product market integration on environmental policy incentives in an international duopoly, where national policy makers act strategically. If traditional trade policy instruments are not available, environmental policies will typically be determined by the interaction of conflicting policy incentives. Contrary to popular belief, we find that international product market integration, in this particular setting, might reduce the need for transnational policy coordination, both from a purely environmental and from a social welfare perspective.  相似文献

Summary. This study develops a real options approach for analyzing the optimal risk adoption policy in an environment where the adoption means a switch from one stochastic flow representation into another. We establish that increased volatility does not necessarily decelerate investment, as predicted by the standard literature on real options, once the underlying volatility of the state variable is made endogenous. We prove that for a decision maker with a convex (concave) objective function, increased post-adoption volatility increases (decreases) the expected cumulative present value of the post-adoption profit flow, which consequently decreases (increases) the option value of waiting and, therefore, accelerates (decelerates) current investment.Received: 12 October 2001, Revised: 4 December 2002, JEL Classification Numbers: O32, G30, D92, C61.

The aim of the study was to evaluate a hospital-based injury recording system on hip fracture registration in elderly persons aged + 65 years from 1994 through 2008, and to examine the agreement between the number of validated fractures and the number of fractures reported to the Norwegian Patient Registry using three different sources: (1) Medical records, (2) Patient administrative system and (3) The hospital's hip fracture record to the Norwegian Patient Registry from 2002 through 2008. The injury recording system included 582 hip fracture events and 535 (92%) were confirmed through the medical records. Reasons for non-verification were different coding failures. Searching the patient administrative system using ICD codes identified 16 hip fractures not included in the fracture registry between 2002 through 2008. The total number was the same as the number of hip fractures reported to the Norwegian Patient Registry using ICD codes alone for identification. The conclusion is that on well-defined diagnosis like hip fractures, local fracture registries may obtain a high degree of reliability if different sources are available for quality control. Well-functioning patient administrative systems may be used to study numbers of hip fractures.  相似文献

We apply cointegration analysis to daily averages of Nord Pool prices covering the period 2001–2007 in order to empirically characterize the geographical dimension of the relevant market for production and wholesale of electricity. We reach the following econometric conclusions: (i) price areas Finland, Sweden, and Norway 3 unambiguously belong to the same relevant market; (ii) Denmark 2 belongs to this same market except for the subsample 2004–2007; (iii) Norway 1 and Denmark 1 define separate markets on their own. We find that the stochastic trends in Nord Pool prices originate in countries abundant in capacity to generate hydro power.  相似文献

This article addresses the relationship between the ethics underpinning leadership and change. It examines the developments in leadership and change over the last three decades and their ethical implications. It adopts a consequentialist perspective on ethics and uses this to explore different approaches to leadership and change. In particular, the article focuses on individual (egoistic) consequentialism and utilitarian consequentialism. The article argues that all leadership styles and all approaches to change are rooted in a set of values, some of which are more likely to lead to ethical outcomes than others. It also argues that all stakeholders in an organisation have a role to play in ensuring ethical outcomes. It concludes that in order to achieve sustainable and beneficial change, those who promote and adopt particular approaches to leadership and change must provide greater ethical clarity about the approaches they are championing.  相似文献

We analyze how a patent‐holding pharmaceutical firm may strategically use advertising of existing drugs to affect research and development (R&D) investments in new (differentiated) drugs, and thereby affect the probability distribution of future market structures in the industry. Within a fairly general model framework, we derive exact conditions for advertising and R&D being substitute strategies for the incumbent firm and show that it may overinvest in advertising to reduce the incentive for an entrant to invest in R&D, thereby reducing the probability of a new product on the market. In a more specific setting of informative advertising, we show that such overinvestment incentives are always present and that more generous patent protection implies that a larger share of the patent rent is spent on marketing, relative to R&D.  相似文献
