Group and individual interviews were conducted to examine relationships developed between children and brands in the family setting. Children's stories about brands suggest that they develop relationships with a wide range of brands and these relationships are imbedded in the social environment where children live and grow. Interpersonal relationship metaphors were utilized to describe different forms of child–brand relationships. The article concludes that children's relationships with brands serve important functions in their lives and have significant implications for marketers. © 2002 Wiley Periodicals, Inc.  相似文献

This article reports the results from two experiments that tested decision‐framing effects on choices made by simulated organizational buying groups. The first experiment showed that the choice of suppliers by buying groups varied depending on the nature of the decision frame. Moreover, group influence seemed to intensify the effect of the loss decision frame. The second experiment tested whether mixed‐frame groups used a lexicographic strategy to make multidimensional supplier choice decisions. Buying groups faced with a choice between two suppliers that differed with respect to price and quality chose the supplier that was best on the most important attribute—quality. Also, the decision frame associated with the important attribute affected the buying groups' choices. © 2002 John Wiley & Sons, Inc.  相似文献

The bias of various estimators for static cross-section and panel data models is assessed in a simulation study, where the actual data generating process is a dynamic adjustment mechanism with random individual effects. It is concluded that the consequences of incorrectly estimating a static model can be rather serious. Therefore, it is important to have an accurate technique available for the detection of dynamics. Two exact similar tests for the presence of a lagged dependent variable in panel data models are developed; in some simulation experiments these tests outperform standard asymptotic test procedures. Empirical results on Engle curves for food illustrate the above issues.  相似文献

Employers seek to manage risk in their group health and life insurance plans through wellness programs and certain hiring practices. In both cases, the Americans with Disabilities Act may ultimately affect the use of these forms of risk rating on the grounds that they are discriminatory.  相似文献

ABSTRACT

Marx's Capital shows that surplus value can be produced in one industry, yet realized as profit (and possibly revenue) by other industries over the course of circulation. This paper highlights the separation between surplus value production and realization in Marx's work, and develops a new method for estimating surplus value production at the industry level to trace out transfers of surplus value across industries. The framework is based on the ‘New Interpretation’ and links money value added to surplus value production at the industry level. Data on value added by industry for the U.S. are used to estimate surplus value production by industry. The analysis allows comparison of surplus value production and realization in each industry. The pattern of differentials between surplus value creation and realization across industries sheds light on the processes of capitalist competition and points to a source of instability for capitalist economies.  相似文献

This article investigates transitions at the level of societal functions (e.g. transport, communication, housing). Societal functions are fulfilled by socio-technical systems, which consist of a cluster of aligned elements, e.g. artefacts, knowledge, user practices and markets, regulation, cultural meaning, infrastructure, maintenance networks and supply networks. To understand how transitions from one socio-technical system to another come about, the article describes a conceptual multi-level perspective. The perspective is illustrated with a historical case study: the transition from horse-drawn carriages to automobiles in the USA (1860–1930). The case study shows that technological substitution approaches to this transition are too simple, because they neglect the electric tram and bicycle, which acted as important stepping stones. The case study also corrects another mistake, namely that the gasoline car won by chance from steam and electric automobiles. It will be shown that particular niches played a crucial role in this competition, as well as the wider socio-technical context. The case study deviates on three points from the multi-level perspective. These deviations are used to conceptualize a particular transition pathway, called ‘de-alignment and re-alignment’.  相似文献

In this paper, we develop a paleoeconomic model of the co-evolution of economic specialization and encephalization—the common physiological measure of intelligence as reflected by brain mass relative to total body mass. Our economic analysis links ecological and social intelligence theories of increased encephalization in early hominins through a model in which both economic and ecological feedbacks jointly determined the evolutionary incentives. We focus on degrees of specialization affected by coordination costs with and without market exchange. Our results suggest encephalization would be a process characterized by diminishing returns to behavioral advances. In terms of the long-running debate in economics over whether specialization increases or decreases intelligence, our results suggest from an evolutionary perspective the answer depends on economic/social institutions and how these influence ecological interactions.  相似文献
