The success of entertainment products such as movies or books varies tremendously, and managers strive to increase the odds by deciding on the right marketing input. Aiming to improve managerial decision making, we suggest and test a quantile regression framework to detect outcome heterogeneity effects of marketing inputs in the entertainment industry. By analyzing the spread of the .9 and the .1 conditioned quantile to the .5 (median) conditioned quantile, we study how much an increase (decrease) of an input factor (star power and quality) changes the spread of the expected outcome (revenues and sales). The spread serves as an indicator for the heterogeneity effect of the input factor regarding the outcome. In two empirical studies, we show how marketing instruments increase (or decrease) outcome heterogeneity by estimating quantile regressions and provide generalizable findings regarding the outcome heterogeneity effects of star power (increases outcome heterogeneity) and quality evaluations (reduces outcome heterogeneity) in the entertainment industry.
In recent years, the emergence of highly successful digital multi-brand retailers has facilitated an omnichannel distribution strategy to become the norm for brands. Rather than relying solely on these multi-brand retailers, it is necessary for companies’ omnichannel strategy to establish strong brand-owned direct-to-consumer (D2C) webstores. To help D2C brands make decisions regarding distribution channel choices, this paper investigates the circumstances under which customers prefer brands’ D2C webstores over digital multi-brand retailers and how these circumstances vary across phases of the customer journey. The results from an extensive experimental study demonstrate that, depending on the customer journey, brands’ D2C webstores can compete with digital multi-brand retailers, particularly in product categories characterized by deep assortments, the need for extensive product information, exclusive products, or a high degree of personalization.
In recent years, service providers have identified the proactive postsales service (PPS) as a viable measure for preempting service failures and their negative consequences. Due to the high costs associated with PPSs, companies are looking for ways to increase their efficiency. To understand how companies can increase their revenues and lower their costs, this study investigates how cross-selling activities and different media types affect the impact of a PPS on inbound service calls and customer churn. Based on a large-scale field experiment in the telecommunications industry, as well as a controlled lab experiment, the results demonstrate the overall effectiveness of the PPS and indicate two mediating effects. While the effect of cross-selling on customer churn and service calls is mediated by the customers’ uncertainty regarding the company’s motives, it is the customers’ perception of privacy invasion that mediates the influence of the contact medium on the effectiveness of the PPS. Our finding that PPS contacts have to be clear in their message and should not be perceived as invasive is an indication of the importance of service-(post)sales ambidexterity.
In the service literature, churn is primarily attributed to customers who are dissatisfied with a service. However, in several industries, such as health care, weight loss services, and online dating, satisfied customers also churn because the service delivers on its promise, for example, by providing a cure, facilitating weight loss, or creating the circumstances that allow a person to meet their partner. Considering these dual churn pathways, it is necessary for companies in these markets to create awareness of what drives positive and negative churn to address the corresponding challenges for managing customer relationships. This study defines and theoretically discusses the concept of positive churn and outlines its consequences for companies in the short- and long term. Based on an analysis of combined observational and survey data from 1,369 customers, we empirically demonstrate the necessity of accounting for positive and negative churn by analyzing this phenomenon in online dating. Furthermore, this article discusses opportunities for future research on positive churn.
Ethical leadership has so far mainly been featured in the organizational behavior domain and, as such, treated as an intra-organizational phenomenon. The present study seeks to highlight the relevance of ethical leadership for extra-organizational phenomena by combining the organizational behavior perspective on ethical leadership with a classical marketing approach. In particular, we demonstrate that customers may use perceived ethical leadership cues as additional reference points when forming purchasing intentions. In two experimental studies (N = 601 and N = 336), we find that ethical leadership positively affects purchasing intentions because of customers’ concerns for moral self-congruence. We show this by means of both mediation and moderation analyses. Interestingly, the effect of perceived ethical leadership on purchasing intentions holds over and above the ethical advertising claims (e.g., cause-related marketing) that are commonly used in marketing. We conclude by discussing the possible ramifications of ethical leadership beyond its effects on immediate employees.
Rewarding existing customers for the recruitment of new ones has become an increasingly popular acquisition tool for companies. However, when a company rewards the recruitment of a new customer, managers are unaware of whether the rewarded referral was actually necessary or whether “reward-scrounging” has occurred because the referral receiver would have converted anyway. As a consequence, companies risk overestimating the effectiveness of their referral programs, which is why gaining insights into how and when reward-scrounging occurs is crucial. In this study, we employ a large data set from the telecommunications industry to analyze the drivers of reward-scrounging. The results indicate that reward-scrounging reduces the effectiveness of referral reward programs over time and that its likelihood depends on both the referral sender's network position and the company's marketing activities. The findings are used to develop managerial means to alleviate the negative effects of reward-scrounging.
Geographic proximity has become increasingly relevant due to the growing number of marketing services that use consumers’ geographic locations, thus increasing the importance of gaining insights from this information. In five studies (both field and experimental), the authors analyze the effect of geographic proximity on social influence and demonstrate that not only social proximity but also perceived homophily can trigger social influence. They find that this effect holds under alternative representations of geographic distance and is confirmed for a range of different services and even for physical goods. Furthermore, the authors show that geographic proximity has a relative effect because the social influence of a closer sender is stronger than that of a more distant sender, regardless of the absolute distances. They present managerially relevant conditions under which the influence of geographic proximity not only is comparable to other types of information such as age or gender but also provides sufficient informational value for customers to offset differences among alternatives (e.g., due to higher prices) in trade-off decisions.
Recent acquisitions involving Tumblr and Instagram have demonstrated that the takeover of an unlisted start-up company can offer enormous financial benefits to its (former) stakeholders. Considering the multimillion-dollar amounts paid for start-ups with no existing and highly uncertain future revenues, we investigate the process and outcome of negotiation dynamics in the context of takeovers. In a series of experiments, we show that even with a low level of uncertainty about a start-up's value and its financial resources, start-ups can influence bidders' behavior and consequently the start-ups' valuation. The results indicate that incumbents' bidding behavior is driven by the perceived threat level with respect to the start-up's business activities as well as by the uncertainty with respect to other incumbents' bidding behavior—drivers that are subject to activities by the start-ups' management. Interestingly, the effect even exists if incumbents clearly know that initiating a bidding process will very likely lead to losses.
In recent years, management and academics have increasingly focused on quality management in public transport. In particular, many public transport operators regularly monitor their service quality over time and use these data to assess quality performance (e.g., for performance-based quality contracts) and to determine managerial decisions (e.g., budget allocations for service improvements). However, despite the widespread applications of service quality data in practice, it is unclear whether cross-sectional analyses and cross-temporal comparisons of service quality data provide valid insights for quality management purposes. In this study, we investigate the usability of cross-sectional analyses and cross-temporal comparisons of service quality data by conducting an empirical study that tracked a panel’s perceptions of the service quality of public transport and its choice over the course of three consecutive years. The results demonstrate that cross-sectional analyses provide valid insights for quality management. However, cross-temporal comparisons should be interpreted carefully because the results of these comparisons are surprisingly unreliable. In fact, we find that service quality data do not provide reliable results over time and therefore conclude that cross-temporal comparisons of service quality data must be interpreted with caution for quality management in public transport.
In recent years, social media have become a popular channel through which customers and companies can interact. However, companies struggle to assess whether their investments in establishing and maintaining brand pages in social media actually meet their high expectations with respect to developing and retaining customers. Based on three empirical studies, the authors explore the role of interactions through corporate social media channels, such as Facebook brand pages, in customer relationship management. The results indicate that social media interactions indeed ease the upselling efforts and reduce the risk of churn. These positive effects offset the observed increases with regard to the number of service requests and the higher overall service cost. Thus, we ultimately find customers who interact with the brand on social media to be more profitable.
The brand personality of nonprofit service organizations (NPO) is a focal cue for individuals engaging in pro-social behavior. However, the positive effect of brand personality on donors’ intention to engage pro-socially may be affected in cases in which NPOs provide monetary incentives to those donors. Relying on social exchange theory, the authors examine how monetary incentives and brand personality commonly affect the intention to donate and whether this effect varies based on the perceived trustworthiness of the NPO. The results of two experimental studies show that branding and incentivizing decisions should not be developed independently because monetary incentives do indeed undermine the positive effects of brand personality on the intention to donate. However, the effectiveness of incentives varies with the perceived level of trust in the NPO: highly trusted NPO services are harmed by monetary incentives, whereas less-trusted NPOs may even benefit.
Referral programs have become a popular tool to use the customer base for new customer acquisition. We replicate the work of Schmitt et al. (2011) who find that referred customers are more loyal and valuable than customers acquired through other channels. While our results confirm that rewarded referrals indeed reduce the risk of customer churn, we do not find that referred customers are necessarily more valuable. Analysis of the relationship between senders and receivers of referrals demonstrates that demographic similarity drives the referred customer value.
Book pricing is problematic for two main reasons. First, because legal restrictions make pricing decisions irreversible. Second, because publishers must set prices for many books every year. Therefore, a sound knowledge of consumer reaction to price is essential for good pricing decisions. Our research examines consumer reactions to prices, provides price elasticities based on a large sample of fiction books, and creates a comprehensive set of quality measures and control variables. Our results show that once price endogeneity is considered, consumers are price elastic. Moreover, we find that the price elasticity for hardcover books is substantially smaller than for paperbacks.
Customer retention is a major driver of customer lifetime value and is thus a key performance metric in marketing management. Consequently, companies try to retain customers by offering contracts with minimum contract durations (MCD). Using behavioral, psychometric, and advertising data for a large sample of DSL customers, the authors study the impact of minimum contract durations on actual customer churn behavior. The analyses demonstrate that subscriptions with minimum contract durations do indeed help companies to successfully retain customers. The effect is impaired though, as companies typically (must) provide incentives to convince customers to commit to those contracts. We find that incentives attract customers that either cannot or should not be retained and hence require companies to carefully apply both MCD and incentives.
When companies launch new products, they need to understand the impact of publicity and advertising on sales. What is their relative effectiveness? Do they strengthen each other (have a positive interaction effect) or weaken each other (have a negative interaction effect)? Further, does the timing of these activities (before or after launch) affect their impact on sales? This paper develops hypotheses regarding the elasticities of pre- and post-launch publicity and advertising on sales. The hypotheses are tested on a large-scale empirical data set that tracks sales, publicity, and advertising for 3336 video games across 52 weeks covering the pre- and post-launch phases. The results demonstrate that pre-launch publicity is more effective than pre-launch advertising but that the reverse is true post-launch. Surprisingly, the analysis reveals a negative interaction effect between pre-launch advertising and publicity, which means that publicity becomes less effective when it is accompanied by higher levels of advertising for the same product. Simulations indicate that companies can gain most sales by focusing on publicity pre-launch, and that there is little benefit from increasing publicity and advertising during the same phase, which is consistent with negative (pre-launch) and zero (post-launch) interaction effects.
For the past decade, customer relationship management (CRM) has been one of the priorities in marketing research and practice. Hence, many companies have invested heavily in CRM systems that, unfortunately, did not meet their expectations. Because such shortcomings may have resulted from unrealistic expectations as well as inappropriate data input, this study provides insights into what companies may expect from CRM and what data they should use. Across the phases of the CRM process, the authors show which CRM objectives have been considered and which customer data have proven to be applicable in the empirical CRM literature. The results indicate that despite differences with respect to influence, a variety of customer data can be used to analyze CRM objectives throughout the entire customer life cycle. Overall, the study provides researchers with a comprehensive review of the empirical research on CRM and offers practitioners insights on the scope of CRM analyses and the applicability of customer data for CRM.
