Price concentration studies investigate the relationship between market concentration and price levels. They are increasingly used in the mobile telecom industry. This paper provides a detailed account of the limitations of such studies. In addition, it proposes a specific approach in order to account for quality differences across countries, which are likely important when explaining price differences. When applying our approach to European mobile telecom markets from 2003 to 2012, we find that there is no positive relationship between concentration and prices and some indications that the relationship may be negative.

This paper focuses on women leaders’ self-views as women and leaders and explores consequences of positive social identity (i.e., positive evaluation of the social category in question) for women in leadership positions. We hypothesized that holding positive gender and leader identities reduced perceived conflict between women’s gender and leader identities and thereby resulted in favorable psychological and motivational consequences. Studies 1 and 2 revealed that positive gender identity indeed reduced women leaders’ identity conflict. In Study 3, we found that by lessening identity conflict, positive gender identity reduced stress, increased life satisfaction, and caused women to construe leading more as an attractive goal than a duty. In contrast, positive leader identity directly affected women’s motivation to lead, but did not reduce their identity conflict. Overall, these results emphasize the protective role of women’s positive gender identity for their advancement in organizations and leader identity development.

Negotiating the pursuit of multiple goals often requires making difficult trade-offs between goals. In these situations, consumers can benefit from using products that help them pursue several goals at the same time. But do consumers always prefer these multipurpose products? We propose that consumers’ incidental mood state alters perceptions of products in a multiple-goals context. Four studies demonstrate that being in a positive mood amplifies perceptions of differences between multiple conflicting goals. As a consequence, consumers are less likely to evaluate multipurpose products as being able to serve multiple distinct goals simultaneously. We conclude by discussing implications of these findings for marketers of multipurpose products.

While much research has been done on how attitudes towards therapy relate to engagement in it, the willingness to engage in coaching has not yet been studied. As coaching continues to grow in popularity and makes its way into curricula of MBA programs, it is worth examining what factors may influence people’s attitudes toward this new type of psychological support. With frequently noticed and discussed similarities between coaching and therapy, this paper examines whether particular antecedents of engagement in therapy, namely mental health stigma and gender, would be equally relevant for engagement in coaching by MBA students.

Previous research has identified customer satisfaction and customer–company identification as two of the most important concepts in relationship marketing. Despite their proclaimed importance, research on their long-term effectiveness is surprisingly scarce. Furthermore, comparative research acknowledging the concepts' different theoretical roots and illuminating the differences in their long-term effectiveness is lacking. Also, little is known about how competitive actions affect the long-term effectiveness of both concepts. This study makes a first attempt to address these research voids and offers a comparative analysis of the effectiveness of customer satisfaction and customer–company identification in driving important customer outcomes over time. Latent growth analyses of rich longitudinal data from customers over nine measurement points spanning 43 weeks (n = 6930) show that customer satisfaction and customer–company identification have positive initial effects on customers' loyalty and willingness to pay, but differ in their ability to maintain these positive effects over time. While the positive effects of customer satisfaction decrease more rapidly, the effects of customer– company identification are significantly more persistent. Analysis of the moderating effects of relative competitive advertising suggests that customer–company identification is more effective at immunizing customers against competitive actions.
