Investigating industry context effects in consumer-firm relationships: Preliminary results from a dispositional approach

Few, if any, past studies have attempted to develop a model to capture and explain industry context variability and hypothesize its effects on consumer-firm relationships. Generally, industry effects are ignored, described, or explained post hoc. Using the notion of consumers' dispositions toward a market, a framework is proposed for understanding the influence of industry context on consumer satisfaction, trust, value, and loyalty in relational exchanges. The empirical results of a survey in two service industries show that industry contexts matter and yield significant direct and moderating effects on consumer-firm relationships. The study underscores the promise of a dispositional approach for providing insights for the theory and practice of relationship marketing, resolvin goutstanding questions, and proposing fruitful areas for further examination.

Old flames never die – the role of binding social ties for corporate entrepreneurship in family firms

This paper investigates the role of social ties and family embeddedness for corporate entrepreneurship in family firms. Family firms are mostly characterized by close and often inseparable ties between the dominant family coalition and the firm and offer specific resources within a context of both rational as well as non-rational factors that influence entrepreneurial strategies. We empirically test (n =?181) the relationship between binding social ties and innovation, strategic renewal, and corporate venturing. Our findings indicate a strong significance for networks and close and stable relationships both to inside the firm and the outside in decision making for corporate venturing and innovation. In contrast, the results for strategic renewal show no relevance of strong social ties. We link up with the debate on the role of owners as an important stakeholder group.
