Equity-Indexed Life Insurance: Pricing and Reserving Using the Principle of Equivalent Utility

Abstract

The author applies the principle of equivalent utility to price and reserve equity-indexed life insurance. Young and Zariphopoulou (2002a, b) extended this principle to price insurance products in a dynamic framework. However, in those papers, the insurance risks were independent of the risky asset in the financial market. By contrast, the death benefit for equity-indexed life insurance is a function of a risky asset; therefore, this paper further extends the principle of equivalent utility. In a second extension, the author applies the principle of equivalent utility to calculate reserves, as introduced by Gerber (1976). In a related paper, Moore and Young (2002) price equity-indexed pure endowments, the building blocks of equity-indexed life annuities.     

Clustering consistency analysis

Cluster analysis is a frequently used technique in marketing as a method to develop partitions or classifications for market segmentation, product positioning, test market selection, etc. Because of the vast diversity in the assortment of clustering algorithms available, it is often times not obvious which algorithm or technique should be employed. It is often recommended that the marketer perform more than one cluster analysis on the same data set and compare representations as a reliability check. A methodology for evaluating the consistency of different clusterings is introduced via contingency table analysis by log-linear models. In addition, insight is provided as to selecting a “best” representative clustering by examining Stewart and Love's (1968) redundancy measures. Bell Laboratories     

The evolution of food retailing systems: Contrasting the experience of developed and developing countries

Most writings on the evolution patterns of food retailing institutions have dealt with developed country experiences. This article reviews the evolution of food retailing systems in the developing economies and relates it to the experience of developed economies. Variations in food retailing systems among countries are related, in a systematic manner, to the differences in the environmental factors. The difficulties of introducing an innovative institution, the supermarket, in developing economies are also discussed.     

Informal group influence among situationally/dispositionally-oriented consumers

Consumer susceptibility to reference group influence has been demonstrated for certain products and buying situations. This article reports a study designed to determine if reference group influence varies between consumers classified as situationally-oriented and dispositionally-oriented. Results indicate a considerable difference between the two groups. Independence Health Plan     

The home purchase process: Measurement of evaluative criteria through pairwise measures

Although the purchase of a home represents a sizable investment for the average family, relatively little consumer research pertaining to the home purchase process has been reported. This investigation utilized Thurstone's Case V methodology to identify key attributes used by consumers to make housing choices and to show how these attributes are perceived by consumers of different tenure and socioeconomic status. The pairwise comparison analysis showed a strong preference for the attributes “safety and security from crime” and “quality construction” by the respondents. In addition, the analysis revealed several important differences in attribute preferences between former owners and former renters. Former home owners, for example, were more likely than former renters to prefer school quality when it was pitted against several other attributes. Thurstone's Case V techniques was found to be an effective method for measuring consumer preferences. Implications which focus on home product development and marketing strategies are discussed.     

An empirical test of the Causative Markov model of consumer behavior

This paper examines an extension of the Markov model of consumer brand switching behavior, which captures the nonstationarity in the consumer decision processes over time. The extended model has been labeled as the Causative Matrix model. The model is put to test on empirical data, and compared with the stationary version of the model. The Causative Matrix model is shown to be a better forecasting tool. Its ability to yield additional insights into consumer brand choice processes is also discussed.     

货币危机的政治经济学解释:文献评述

作者从文献的角度对货币危机的政治经济学解释做了一次比较全面的梳理,从中可以看出国际金融政治经济学的研究特点和思维方式。在理论构建上,政治经济学的学者们完全沿用了经济学模型中的不完全信息和动态博弈论,引入了预期的形成以及市场交易者和政府之间的战略互动,从而成功地把各种政治和经济变量纳入到一个模型之内。他们的贡献是,把政治变量引入到市场交易者和政府的预期形成中,强调了政治变量以及作为一种信息的政治变量在市场交易者和政府预期中的作用或者地位,并强调了政治变量在市场交易者和政府之间战略互动或动态博弈过程中的作用,从而更好地解释了货币危机的原因,提高了预测货币危机的准确性。在实证研究上,政治经济学通过预期效用函数、战略概率模型等方式,较为成功地实现了对政治因素这个分类变量的模型化,较好地实现了对政治因素的量化分析。     

国际调停发生的讨价还价模型:一种定量检验

国际冲突是否经历调停是由调停的供给方(即调停者)和需求方(即争端方)共同决定的。与既有大多数研究强调影响调停发生的"深层原因"不同,作者借鉴理性主义解释视角,着重关注影响调停发生的"即时原因",即将调停的发生视为需求方讨价还价成功的结果。根据理性主义的解释,影响需求方讨价还价结果的主要障碍有私有信息(包括故意误传私有信息)、承诺问题和议题不可分割性三种,而第三方调停者的干预可以帮助需求方克服这三种障碍,从而增加调停发生的可能性。作者使用"国际危机行为"和"国际冲突管理"两个数据库数据,运用统计方法检验了调停发生的讨价还价模型。统计结果表明,当影响需求方之间讨价还价结果的三种问题得到有效管理时,国际冲突更容易经历调停。     

The marketing concept in perspective

A re-evaluation of the marketing concept appears to be in the making. The focus of research designed to facilitate this re-evaluation is likely to be of considerable importance to the future development of marketing theory. Research designed to better define the role and scope of the marketing concept seems to offer the most promise. Such research would be an aid to determining where the marketing concept should fit into a comprehensive theory of marketing. Limitations of the marketing concept are well documented in the literature suggesting a need for a broader framework of marketing theory. It seems imperative that academicians accept the responsibility for developing a more comprehensive general theory of marketing, one relevant to both the micro and macro aspects of a functioning system. Such flexibility seems to be a minimal requirement.
