Online activism is a modern-day phenomenon present within online communities. Sustainable fashion is a current movement resulting from consumers' heightened environmental awareness and organisations becoming ‘greener’. Driven by hashtags, online communities are hubs for lobbyists and influencers who desire change from clothing brands. This study undertook focus groups and interviews to probe users’ lobbying behaviours via knowledge sharing within an online community. Two user types emerge. One shares knowledge to lobby others, driven by a desire for change. The other shares knowledge, led by their green beliefs, resulting in unintentional lobbying for change. This paper contributes insight into online lobbyists' behaviours and drivers. The challenge is to encourage online users to realise there will be consequences, intended or not. In the case of a ‘good cause’ such as sustainability, a moral concern does not justify what others might view to be unethical behaviour, heavy-handed pressurising or misleading lobbying.

Market systems research focuses on how discursive negotiations among market stakeholders spur change and determine what becomes “valuable and virtuous” or “worthless and immoral”. Surprisingly, we know little about the role of temporality in market change and its impact on market speeds. Based on a comparative discourse analysis of news media coverage of robots in Britain (3,023 articles) and the United States (2,104 articles), we find that market systems create culturally informed discourses about the future, which in turn establish the moral regime within which market stakeholders must operate. The moral regime in a local cultural context is a consensus on the resources available to describe desirable and disagreeable future outcomes of market-driven change. We find that the US is morally permissive towards robot technologies by highlighting their potential to contribute to a service-oriented convenience society. The UK is morally restrictive towards the same technologies by invoking the UK’s class system and highlighting robot technologies’ potential to take away workers’ rights and work itself. UK market stakeholders want the future to slow down, while US market stakeholders want it to speed up. As a result, we observe that market systems function as “time machines” that determine market speeds, i.e., how fast the future is permitted to arrive in a particular cultural context.

“How to Do Well by Doing Good: A Meta-Analysis of the Effectiveness of Cause-Related Marketing”

Cause-related marketing (CM) ties a brand’s philanthropic engagement to a sales promotion. Due to its dual nature, CM has been shown to evoke both positive (warm glow) and negative (consumer skepticism) consumer responses. Yet, current research has produced inconclusive evidence, and it is unclear to what extent and under what conditions (moderators) CM influences attitudinal and behavioral outcomes. This meta-analysis therefore synthesizes the empirical evidence about both the CM main effect and relevant CM moderators across 160 papers, reporting 229 studies. The authors find a moderate and positive main effect of CM. This effect is highly contingent on factors related to four dimensions: the for-profit partner, the non-profit partner, the donation, and the campaign communication. In particular, the meta-analysis reconciles previously inconclusive evidence on the most studied CM moderators (fit between the for-profit and the donation target, hedonic product type, donation level) and further reveals several significant novel CM moderators. Overall, the generalizations inform researchers and managers about expected effect sizes when executing CM, compare its effectiveness to other CSR activities and price promotions, and provide a systematic agenda for further research.

User-generated content (UGC) platforms provide consumers with access to content that is uploaded by users who do not hold the copyright to this content, and these platforms are not liable for restricting users from uploading the content due to “safe harbor” provisions. On many UGC video streaming platforms (e.g., YouTube) music is among the most popular content, raising the question of whether UGC platforms are beneficial for rights holders in the music industry (e.g., music labels and artists). On the one hand, UGC platforms pay fees to rights holders and may divert consumers from illegal piracy sites. On the other hand, these fees are only a fraction of what subscription-based audio streaming services (e.g., Spotify) pay, and UGC platforms may hinder the adoption of these services and displace paid downloads. Despite the ongoing controversial public debate, the relevance and magnitude of these effects have not been studied. To analyze how UGC video music streaming impacts (1) music consumption in other channels and (2) the total recorded music revenue, we compile a dataset covering music consumption via all major channels for 790 songs over a period of more than two years. We investigate these relationships using a simultaneous equation system and find that although UGC video streaming services generate income and reduce piracy, their effect on total revenues is negative because of the cannibalization of paid downloads and audio streaming channels.

Cookies enable companies to collect and exchange extensive information about users. This information is often used to improve the performance of online advertising. Yet, the collection of information leads to a loss of privacy. Accordingly, EU policy makers have put forward initiatives to restrict cookie usage. So far, there exists very little empirical knowledge on the trade-off between user privacy and the economic value that website publishers, advertisers, and even users derive from cookies. As a result, policy makers have no way of telling whether their restrictions on cookies have the intended positive consequences for user privacy, or whether any benefits are outweighed by negative effects on the profits of companies. To begin to fill this gap on the cost side of this discourse, we estimate the potential upper-bound of an economic loss for digital publishers of lifespan restrictions on cookies. Our analysis is based on an empirical study on cookies of 54,127 users who received about 130 million ad impressions over almost 2.5 years. Restricting their lifetime to one year as the European Union proposes decreases their cookie lifetime value by 14.1%. In light of the €10.6 Bn. cookie-based display ad revenue in Europe, such restrictions would endanger each year €180 Mio.

In an era of rapidly changing and evolving markets, firms’ marketing agility has become a key driver of competitive advantage. Marketing agility, however, requires very timely and ongoing insights into markets. Over the past decade, marketers have thus turned to a rich, abundant and very timely data source, namely user-generated-content (UGC). Extracting insights from UGC, however, is challenging since such data are usually very big and unstructured. To overcome this challenge, researchers recently started to employ methods from the field of natural language processing (NLP) such as the popular word2vec model. However, it suffers from two major shortcomings: 1) it is unable to distinguish between multiple meanings of a word, and 2) it does not capture changes over time. We overcome the shortcomings of word2vec with a new model named Dory that is inspired by human memory-systems. As we show by simulation and in an empirical application, Dory’s additional qualities of human memory-systems enable it to detect patterns in consumers’ brand perspectives that remain undetected by extant models.

Digitalisierung ist das Schlagwort der Stunde. Vielfach wird damit ein revolutionärer Wandel in Verbindung gebracht, der traditionelle Branchenstrukturen innerhalb kurzer Zeit auf den Kopf stellt und bestehende Unternehmen durch neue Geschäftsmodelle verdrängt. Dabei wird «neu» und «innovativ» auch gleichzeitig als «gut» verstanden. Vielfach werden dabei aber grundlegende Fundamente der Digitalisierung vernachlässigt und falsch interpretiert. Auf Basis der Ergebnisse verschiedener Forschungsprojekte und Unternehmenskooperationen zeigt der Vortrag die grundlegenden Treiber der Digitalisierung auf, ver-sucht Missverständnisse auszuräumen und die Entwicklungschancen aus einer marktori-entierten Perspektive aufzuzeigen.

Zur Person:

Prof. Dr. Marcus Schögel ist Direktor des Instituts für Marketing an der Universität St. Gallen und Leiter des neukonzipierten Masters in Marketing Management. In der Forschung beschäftigt er sich mit den Herausforderungen, die sich aus einer «interaktionsorientierten Marketingperspektive» ergeben. Er arbeitet dabei an der Bewältigung der Herausforderungen von kundenzentrierten Unternehmensstrategien, marktorientierten Veränderungsprozessen in Unternehmen und der Realisierung von erfolgreichen Go to marketStrategien.


Healthy eating strategies can be based on approach (foods one should eat) or avoidance (foods one should not eat). Previous research has reported mixed findings for the effectiveness of these strategies. The current research examines whether weight status moderates the effectiveness of approach and avoidance strategies in goal pursuit. Using an ideal weight goal context, this research shows that approach strategies motivate goal-consistent behaviors among people with poor weight status by increasing the perceived attainability of the goal. Avoidance strategies are more motivating among people with good weight status because they decrease the perceived progress toward the goal, which increases the perceived need for additional effort in the form of goal-consistent behaviors to ensure timely attainment.

As of 2017, a third of internet users worldwide has “used a mobile payment service in the last month”, with forecasts projecting over 1.1 billion proximity mobile payment users worldwide by 2021 (Statista, 2019). Mobile payment methods and apps are key technologies of interest to managers, who are unsure about the business impact. This is one of the first studies to differentiate between different forms of cashless mobile payments: SMS mobile payment only, SMS mobile payers who downloaded the app but never switched to app mobile wallet, and mobile wallet users. For a large, international beverage brand sold in vending machines, difference-in-difference-in-differences (DDD) methodology we find that different forms of mobile payments have different potential to impact purchase behavior.

The paper challenges two conventional notions: that changes in costs are not completely pass-through to the customer, and that this pass-through is asymmetric (cost increases are more likely to be passed through than cost decreases). We show that what looks like incomplete pass-through can also be seen as the salespeople passing-through the cost over time, i.e., in later transactions. We also show that the asymmetry that has been reported in the literature depends on the price level at which a salesperson is operating and it can go in either direction.
