The research focus is individuals who have information about many kinds of products, places to shop, and other facets of the market, and initiate discussions with and respond to information requests from other consumers. Specifically, the authors develop a Likert-type scale to measure consumers’ propensity to provide general shopping and marketplace information. Consumers scoring high on this scale are referred to as “market mavens.” Based on a national sample of 1531 households, the findings indicate that market mavens exist and that other consumers recognize them. Consumers believe market mavens are influential in their purchasing decisions. The authors document the distinctness of market mavens from other influencers. They test several propositions about the market attitudes and behaviors of market mavens, but find no clear socioeconomic and demographic profile of these influencers. The results have implications for marketing managers and suggest a reexamination of the approach to information diffusion.

The main objective of customer satisfaction programs is to increase customer retention rates. In explaining the link between customer satisfaction and loyalty, switching costs play an important role and provide useful insight. For example, the presence of switching costs can mean that some seemingly loyal customers are actually dissatisfied but do not defect because of high switching costs. Thus, the level of switching costs moderates the link between satisfaction and loyalty. The purposes of this paper are: to examine the moderating role of switching costs in the customer satisfaction‐loyalty link; and to identify customer segments and then analyze the heterogeneity in the satisfaction‐loyalty link among the different segments. An empirical example based on the mobile phone service market in France indicates support for the moderating role of switching costs. Managerial implications of the results are discussed.

Drawing on our work in two postsocialist countries, Hungary and Romania, we contribute to understanding product involvement and brand commitment. We demonstrate that prominent political-cultural discourses, cultural intermediaries, social influences, and life themes and projects collectively prompt product involvement. We introduce the concept of involvement with branded products and examine its origins within a sociohistorical context. We consider the origins of brand commitment and illustrate that consumers with little interest in either the product category or the idea of branded products may be committed to particular brands. Further, we contribute to understanding the relationships among product involvement, brand commitment, and brand experimentation.
