In this paper, we argue that, once the costs of maintaining the hedging portfolio are properly taken into account, semistatic portfolios should more properly be thought of as separate classes of derivatives, with nontrivial, model‐dependent payoff structures. We derive new integral representations for payoffs of exotic European options in terms of payoffs of vanillas, different from the Carr–Madan representation, and suggest approximations of the idealized static hedging/replicating portfolio using vanillas available in the market. We study the dependence of the hedging error on a model used for pricing and show that the variance of the hedging errors of static hedging portfolios can be sizably larger than the errors of variance‐minimizing portfolios. We explain why the exact semistatic hedging of barrier options is impossible for processes with jumps, and derive general formulas for variance‐minimizing semistatic portfolios. We show that hedging using vanillas only leads to larger errors than hedging using vanillas and first touch digitals. In all cases, efficient calculations of the weights of the hedging portfolios are in the dual space using new efficient numerical methods for calculation of the Wiener–Hopf factors and Laplace–Fourier inversion.  相似文献

We consider the problem of hedging a contingent claim with a “semistatic” strategy composed of a dynamic position in one asset and static (buy‐and‐hold) positions in other assets. We give general representations of the optimal strategy and the hedging error under the criterion of variance optimality and provide tractable formulas using Fourier integration in case of the Heston model. We also consider the problem of optimally selecting a sparse semistatic hedging strategy, i.e., a strategy that only uses a small subset of available hedging assets and discuss parallels to the variable‐selection problem in linear regression. The methods developed are illustrated in an extended numerical example where we compute a sparse semistatic hedge for a variance swap using European options as static hedging assets.  相似文献

We develop a general framework for statically hedging and pricing European‐style options with nonstandard terminal payoffs, which can be applied to mixed static–dynamic and semistatic hedges for many path‐dependent exotic options including variance swaps and barrier options. The goal is achieved by separating the hedging and pricing problems to obtain replicating strategies. Once prices have been obtained for a set of basis payoffs, the pricing and hedging of financial securities with arbitrary payoff functions is accomplished by computing a set of “hedge coefficients” for that security. This method is particularly well suited for pricing baskets of options simultaneously, and is robust to discontinuities of payoffs. In addition, the method enables a systematic comparison of the value of a payoff (or portfolio) across a set of competing model specifications with implications for security design.  相似文献

We price an American floating strike lookback option under the Black–Scholes model with a hypothetic static hedging portfolio (HSHP) composed of nontradable European options. Our approach is more efficient than the tree methods because recalculating the option prices is much quicker. Applying put–call duality to an HSHP yields a tradable semistatic hedging portfolio (SSHP). Numerical results indicate that an SSHP has better hedging performance than a delta-hedged portfolio. Finally, we investigate the model risk for SSHP under a stochastic volatility assumption and find that the model risk is related to the correlation between asset price and volatility.  相似文献

Classical put–call symmetry relates the price of puts and calls under a suitable dual market transform. One well‐known application is the semistatic hedging of path‐dependent barrier options with European options. This, however, in its classical form requires the price process to observe rather stringent and unrealistic symmetry properties. In this paper, we develop a general self‐duality theorem to develop valuation schemes for barrier options in stochastic volatility models with correlation.  相似文献

PUT-CALL SYMMETRY: EXTENSIONS AND APPLICATIONS   总被引:2,自引:0,他引:2  
Classic put-call symmetry relates the prices of puts and calls at strikes on opposite sides of the forward price. We extend put-call symmetry in several directions. Relaxing the assumptions, we generalize to unified local/stochastic volatility models and time-changed Lévy processes, under a symmetry condition. Further relaxing the assumptions, we generalize to various  asymmetric  dynamics. Extending the conclusions, we take an arbitrarily given payoff of European style or single/double/sequential barrier style, and we construct a conjugate European-style claim of equal value, and thereby a semistatic hedge of the given payoff.  相似文献

Average effects of influence strategies on consumers' attitudes and behaviors have been studied extensively. Less is known about the relative size of individual differences in these effects, despite recognition of their importance in social psychology. Two experiments use repeated exposures to influence strategies to identify the effects of each social influence strategy for individual participants. Study 1 provides evidence of large variation in the effects of influence strategies, such that for many participants the estimated effect of using an influence strategy is negative, even though the effect of that strategy is significantly positive on average. Study 2 replicates these findings over three sessions, each a week apart. The observed variation in responses to influence strategies cannot be attributed to transient intra-individual variation (e.g., strategy × mood interactions). Meta-judgmental measures of personality constructs (e.g., need for cognition) explain only a small portion of the observed variance, suggesting the importance of directly modeling heterogeneity in responses to influence attempts. These results are important for interactive marketeers since they indicate that different influence strategies substantially differ in their effects on individual consumers and should thus be adapted to individuals.  相似文献

The purpose of this study is, by means of studying the changes in Chinese advertisements’ contents and forms over a decade, to evaluate the advertising westernization in China and to provide suggestions for Chinese companies in selecting proper advertising strategies. If relatively typical Western cultural characteristics are presented in Chinese advertisements, it indicates that the cultural distance between East and West is reduced, and standardization strategies may be a better choice for foreign enterprises. Otherwise, they should adopt specialization or combined strategies.   相似文献

The degree to which a firm's performance is dependent on its resources and strategies is widely debated in the literature. We examine this issue by analyzing historical data on the entire population of new independent firms started worldwide in the semiconductor silicon industry for the first 50 years of its existence. We measure resources (managerial capabilities and technological competencies) and strategies (emphasis on demand pull or technology push) at the time of founding and test their relationship with each other as well as with multiple measures of performance (lifespan and best year's sales). We find that firms founded on managerial capabilities emphasize demand-pull strategies at founding, whereas firms founded upon technological competencies emphasize technology-push strategies at founding. We also find that firms emphasizing technology-push strategies perform better than firms emphasizing demand-pull strategies. Lastly, we find that though managerial capabilities are related to a firm's best year's sales, this relationship is mediated by the firm's founding strategy.  相似文献

This article focuses on organizations' continued struggles to design and implement successful and credible reward strategies. We argue that a major and neglected factor that accounts for this is how reward strategies are designed and executed with insufficient attention given to employee preferences for different types of reward. We argue that this is both a problem of process in the way reward systems are designed and a problem of how models of reward strategy are built. Developing more effective reward strategies requires a better understanding of holistic rewards and greater attention to line management roles in their implementation. © 2010 Wiley Periodicals, Inc.  相似文献

Abstract

Promotional strategies used by manufacturers (or retailers) influence not only their own outcomes, but also the outcomes of retailers (or manufacturers). As cooperation of both the parties is needed for successful implementation of promotional strategies, the promotions used by either party should provide outcomes that are positive for the other party. The authors propose a framework for examining (1) the effect of promotional strategies on both manufacturer and retailer profitability and (2) which of two promotional strategies (retail price cut or coupon promotion) yields greater total profitability to achieve an exogenously given sales level. The proposed framework also helps in identifying conditions when conflict is likely to occur between manufacturer and retailer, and suggests a cooperative strategy to resolve the conflict.  相似文献

Abstract

Developing and maintaining a brand image is vital to any successful marketing and communication campaign. An image that clearly communicates the needs satisfied by the brand contributes to brand equity and helps combat brand parity. The normative model of brand image management suggests that marketers should base their images on a single set of consumer needs (depth strategy), rather than multiple sets of needs (breadth strategy). The extent to which depth strategies outperformed breadth strategies (in terms of annual change in sales volume, profit margin, and market share) was investigated for U.S. consumer goods exported into international markets. These markets varied in terms of level of economic development, cultural context, and competition. While the results indicate that depth strategies do tend to perform best, there are conditions under which breadth strategies perform just as well.  相似文献

ABSTRACT

With increasing emphasis on relationship selling, a bond is often formed between the salesperson and each customer. When a salesperson leaves to work for a competitor, customers may follow. Small companies are particularly vulnerable since they lack the resources necessary for many sales force retention strategies. The suggestion is made that such companies can implement “bridging strategies,” company-level relationship strategies designed to supplement the relationship between the sales rep and the customer, with the distinct objective of retaining customers following salesperson defection. Using the three levels of relationship marketing described by Berry and Parasuraman (1991), specific bridging strategies are identified and analyzed. The pharmaceutical industry is discussed as an example.  相似文献

In recent years, the metaverse has garnered significant attention as a term referring to a network of 3D virtual worlds that integrate elements of both physical and digital worlds. Fashion brands have begun exploring the metaverse as a new marketing platform, which is expected to bring about substantial changes in the fashion and retail industry. However, a lack of consensus on the nature of the metaverse and its impact on the fashion industry currently exists, and limited academic research is available on the metaverse's influence on fashion brands' marketing strategies and brand experiences. To address this gap, this study employs a thematic analysis approach on trade journals and industry articles that cover fashion brands' metaverse strategies. Through this analysis, the study provides a typology of current marketing strategies of fashion brands in the metaverse. Based on these empirical findings, this research proposes a theoretical framework that explains how different metaverse strategies affect different dimensions of brand equity. Finally, this study offers research directions for fashion brands' metaverse strategies by presenting an integrated framework that synthesizes the key insights from our research findings.  相似文献

ABSTRACT

This qualitatively-based empirical research explored the strategies used by two museums to manage their roles in co-production as well as how they manage, motivate and guide visitors through the process of co-production. We also gained insights into how visitors responded to these strategies. Our findings suggest that the two museums employ different strategies to co-produce the consumption experience and that their strategies were linked to the nature of authenticity that is apparent in the museums. Strategies included explicitly controlling the visitor experience through empowering visitors to design their own visitor experience. The success of these strategies relied on the two museums recognising the situational variables of the context of consumption and adopting appropriate strategies that enabled them and the visitors to leverage the value of the visitor experience. The findings from this study suggest that further research should be undertaken on how authenticity might be integrated into a service-dominant logic paradigm and service strategies aimed at enhancing the co-creation of value.  相似文献

Engaging in unethical consumption behaviors is an acute societal problem that can have severe consequences for adolescents, and businesses in particular have been accused of making such consumption particularly appealing and accessible. However, the causes of unethical behaviors are not well understood and research on the causes has been mixed. In this research, we investigate the effects of coping strategies for loneliness on adolescents’ adoption of unethical behaviors, a topic that business ethics research has not explored. In a large-scale study (n = 409) of adolescents (ages 13–17), we show that whether loneliness leads to the adoption of unethical behaviors depends on the strategies adolescents use to cope with their loneliness: active coping strategies are associated with fewer unethical behaviors, whereas passive coping strategies are associated with more unethical behaviors. In addition, we show that active and passive coping strategies can be executed through consumption practices. We show that the relation between active coping and fewer unethical behaviors is mediated by sharing of possessions, whereas the relation between passive coping strategies and more unethical behaviors is mediated by product acquisition. Finally, we also show that these mediated relations differ as a function of age cohort (grade level). The indirect effect of active coping on fewer unethical behaviors via sharing holds only for middle school adolescents, whereas the indirect effect of passive coping on more unethical behaviors via product acquisition holds only for high school adolescents. We shed new light on both the bright and dark sides of materialism and unethical behaviors and provide practical implications for research on loneliness, business ethics, and unethical behaviors.  相似文献

We examined firm-level and country-level antecedents of R&D internationalization strategies, focusing on differences between enterprises in emerging and advanced economies. Previous research often focuses on the relative importance of home-base-exploiting versus home-base-augmenting knowledge transfer strategies. We suggest that country-level and firm-level effects differ for the two strategies, and hence, we examined each strategy independently. Collecting data in China, India, the United States, and Germany, we demonstrated that firms' relative technological position as a firm-level characteristic can explain differences in home-base-exploiting strategies between emerging and advanced economies. In contrast, home-base-augmenting is more closely related to exploratory institutional environments, a country-level factor. Thus, either firm- or country-level antecedents can gain a dominant role, depending on the strategy implemented.  相似文献

ABSTRACT

The concept paper adopts a positioning type for the purpose of branding services in a transitioning economy. The consumer-based typology is deemed appropriate and relevant as it represents consumer expectations, reflecting the paper’s key argument that consumer-based positioning strategies are appropriate for branding purposes. Consequently, the paper adopts a positioning type for illustrative purpose. The three positioning strategies adopted were—‘service reliability’, ‘social responsibility’, and ‘branding’ apply to the Ghanaian context. The ‘service reliability’ strategy has a ‘universal’ appeal and is the most prevalent in application. The ‘social responsibility’ to a large extent reflects the caring and community-based nature of the Ghanaian society, whilst the ‘branding’ strategy appears more applicable to international than local firms. The paper contributes to theoretical knowledge in its key assertion that the application of consumer-based positioning strategies for branding is appropriate and beneficial. Practically, the derived propositions will guide the manager in decision making on branding.  相似文献

This study employed a content analysis of the creative strategies present in the social media content shared by a sample of top brands. The results reveal which social media channels are being used, which creative strategies/appeals are being used, and how these channels and strategies relate to consumer engagement in branded social media. Past research has suggested that brands should focus on maintaining a social presence across social channels with content that is fresh and frequent and includes incentives for consumer participation (Ling et al., 2004). This study confirmed the importance of frequent updates and incentives for participation. In addition, several creative strategies were associated with customer engagement, specifically experiential, image, and exclusivity messages. Despite the value of these creative approaches, most branded social content can be categorized as functional.  相似文献
