Consumers evaluate products with all their senses but exhibit considerable variability in the extent to which they actively use and rely on a specific sense. We know little about the variability in consumers’ propensity to actively engage their sense of smell in the context of product evaluation in purchase decision making. This research provides insights into this issue by conceptualizing the need for smell construct, detailing the development of the ENFAS scale, and providing state-of-the-art psychometric evidence of its validity. Ten studies contributed to a two-dimensional 11-item instrument, supporting the scale's external and cross-national validity, and establishing the position of need for smell in its nomological net. The results yield insight into how smell perception affects consumer choices and may help optimize product presentations for the retail context.@en

Social media offers a myriad of opportunities for entrepreneurial marketing strategies that leverage the power of communities, especially when they are combined with traditional approaches such as celebrity endorsement. The reach, frequency, and speed of communication on social media offer the ideal leverage for the drivers of entrepreneurial marketing. However, the rapid rate of change may threaten the effects of investments in entrepreneurial marketing on social media and they might become only short-lived. Employing structural equation modeling, we test the long-term effect of Facebook-based celebrity endorsement on purchase intention among 234 members of a Facebook fan community in a two-wave longitudinal design. We argue that this relationship is mediated by a sponsor's brand image and moderated by brand differentiation. This study is the first to investigate the long-term effects of entrepreneurial marketing on social media. We present the contributions and implications of our findings as they affect research and practice.@en
