The Backfire Effect of Sustainable Social Cues. New Evidence on Social Moral Licensing

8th March 2022
KCG Secretary
Authors: WassiliLasarov, RobertMai, StefanHoffmann (Ecological Economics, 2022, 195 : 107376)

To encourage individuals to consume sustainably, managers and policymakers often highlight positive examples that others have set regarding sustainable consumer behavior (e.g., donations to a good cause). This study shows that under certain circumstances, this strategy provokes a paradoxical effect such that consumers deliberately deviate from these positive examples[...]

Vanishing Boycott Impetus: Why and How Consumer Participation in a Boycott Decreases Over Time

8th March 2022
KCG Secretary
Authors: Wassili Lasarov, Stefan Hoffmann, Ulrich Orth (Journal of Business Ethics, forthcoming)

Media reports that a company behaves in a socially nonresponsible manner frequently result in consumer participation in a boycott. As time goes by, however, the number of consumers participating in the boycott starts dwindling. Yet, little is known on why individual participation in a boycott declines and what type of consumer is more likely to stop boycotting earlier rather than later. Integrating research on drivers of individual boycott participation with multi-stage models and the hot/cool cognition system, suggests a “heat-up” phase in which boycott participation is fueled by expressive drivers, and a “cool-down” phase in which instrumental drivers become more influential[...]

KCG Secretary
Authors: Robert Mai, Stefan Hoffmann, Ingo Balderjahn (Journal of the Academy of Marketing Science, 2021, 49: 1151–1174)

The organic market is characterized by remarkable disparities, and confusion persists about which motives drive organic consumption. To understand them, this research introduces the idea that the same consumer motives can exert different and potentially opposite impacts when organic consumption patterns unfold[...]

Indirect rebound effects on the consumer level occur when potential greenhouse gas emission savings from the usage of more efficient technologies or more sufficient consumption in one consumption area are partially or fully offset through the consumers’ adverse behavioral responses in other areas[...]

Too Cold to Be Skeptical: How Ambient Temperature Moderates the Effects of CSR Communication

19th November 2021
KCG Secretary
Authors: Wassili Lasarov, Robert Mai, Jan S. Krause, Ulrich Schmidt, Stefan Hoffmann (Ecological Economics , 2021, 183, Article: 106943)

Consumer reactions to firms' corporate social responsibility (CSR) communication range from favorable approval to outright skepticism toward the company. This paper contributes to the CSR literature by introducing a so-far overseen but relevant variable that helps to explain why consumer sometimes react positively and sometimes negatively to CSR communication: the ambient temperature[...]

Virtue Ethics between East and West in Consumer Research: Review, Synthesis and Directions for Future Research

19th November 2021
KCG Secretary
Authors: Guli-Sanam Karimova, Nils Christian Hoffmann, Ludger Heidbrink, Stefan Hoffmann (Journal of Business Ethics, 2020, 165: 255–275)

This literature review systematically synthesizes studies that link consumer research to differences and similarities in virtue ethics between the East and the West, with a focus on early Chinese and ancient Greek virtue ethics. These two major traditions provide principles that guide consumer behavior and thus serve as a background to comparatively explain and evaluate the ethical nature of consumer behavior in the East and the West[...]

KCG Policy Paper No. 7: Ein Lieferkettengesetz für Deutschland?

12th February 2021
KCG Secretary
Authors: Holger Görg, Aoife Hanley, Ludger Heidbrink, Stefan Hoffmann, Till Requate

Ein Lieferkettengesetz kann einen starken Anreiz dafür setzen, dass deutsche Unternehmen sich für nachhaltige Sozial- und Umweltbedingungen in globalen Lieferketten einsetzen. Dabei sollte jedoch überdacht werden, ob es zum jetzigen Zeitpunkt nicht sinnvoller wäre, eine gesetzlich vorgeschriebene Haftung durch eine zunächst zeitlich befristete Selbstverpflichtungsphase zu ersetzen oder zu ergänzen[…]

KCG Researchers Investigate Consumer Roles in Collaborative Consumption

9th August 2019
KCG Secretary
The rapid development of new digital technologies has facilitated the formation of new e-business ideas. Many of these ideas can be seen as the implementation of a new collaborative form of consumption and production and are expected to have their potential economic impact beyond national boundaries. Here economic agents take both roles of consumers and suppliers. This makes them different from the traditional business models where the classic supplier-consumer dualism usually applies[…]

Hungry Bellies Have No Ears. How and Why Hunger Inhibits Sustainable Consumption

12th July 2019
KCG Secretary
Authors: Stefan Hoffmann, Robert Mai, Wassili Lasarov, Jan Krause and Ulrich Schmidt (Ecological Economics, Vol. 160, 96-104)

While reports state that consumers are increasingly willing to consume more sustainably, no study has considered how the activation of very basic human needs, such as the state of hunger, affects sustainable food consumption. The authors expect that hungry consumers display a lower preference for sustainable food items and that this hunger-induced[…]

Ethical Products = Less Strong: How Explicit and Implicit Reliance on the Lay Theory Affects Consumption Behaviors

21st December 2017
KCG Secretary
Authors: Robert Mai, Stefan Hoffmann, Wassili Lasarov and Arne Buhs (Journal of Business Ethics, 2019, Vol. 158, 659–677)

Many consumers implicitly associate sustainability with lower product strength. This so-called ethical = less strong intuition (ELSI) poses a major threat for the success of sustainable products. This article explores this pervasive lay theory and examines whether it is a key barrier for sustainable consumption patterns. Even more importantly, little is known about the underlying mechanisms that might operate differently at the implicit[…]

The Tenure-Based Customer Retention Model: A Cross-Cultural Validation

21st December 2017
KCG Secretary
Authors: Carolin Krauts and Stefan Hoffmann (Journal of International Marketing, 2017, Vol. 25(3), 83-106)

International businesses and their marketing managers face complexity in the targeting of different customer groups in multiple countries, with different purchase histories and brand relationship tenures. Thus far, no customer retention model has been suggested to sufficiently reduce such complexity. To fill the gap, this study distinguishes three global customer groups—brand stayers, brand switchers, and category novices[…]

Consumer Response to Unethical Corporate Behavior: A Re-Examination and Extension of the Moral Decoupling Model

21st December 2017
KCG Secretary
Authors: Kristina Haberstroh. Ulrich Orth, Stefan Hoffmann and Berit Brunk (Journal of Business Ethics, 2017, Vol. 140(1), 161-173)

This research replicates Bhattacharjee et al. (J Consum Res 39(4):1167–1184, 2013) moral decoupling model and extends the original along the dimensions of theory, method, and context. Adopting a branding perspective and focusing on the corporate domain rather than the public figures investigated by Bhattacharjee and colleagues, this research examines the proposition that consumers dissociate judgments of morality from judgments of performance to justify purchasing from companies deemed to act immorally[…]
