Data and operationalization of variables
Variable | Description | Measurement unit | Mean | SD | ||
---|---|---|---|---|---|---|
Dependent variable | Customer retention (M/B) | Monthly measured dummy variable: 1 = customer i remains with the focal firm for mobile/broadband service category at time t; 0 = otherwise | Monthly | .8704/.8983 | .1064/.0937 | |
Lock-in | Lock-in (bundling) | Bundling reflects whether customer i is locked into the exchange relationship with firm m at time t − 1, based on whether they have acquired the two service categories (i.e., mobile and broadband) in a bundled manner Monthly measured dummy variable: 1 = customer i has acquired both the mobile service and the broadband service from the same service provider; 0 = customer i has acquired only one service (i.e., mobile or broadband) from the provider | Monthly | .1465 | .3536 | |
Lock-in (binding contract) | Binding contract is a customer-specific variable that refers to whether customer i is locked into the exchange relationship with firm m at time t − 1 based on the number of months required at time t − 1 to complete the initially agreed contractual length. This fluctuates between 0 and 36 months, varies across individual customers depending on different aspects, and decreases month by month | Monthly | 5.4631 | 3.9523 | ||
Affective customer experience (CX) | Affective CX (M) | Affective customer experience of customer i of the focal firm’s mobile services measured through NPS via a survey in December of each year from 2013 to 2016 (0 = very unlikely, 10 = very likely) | Yearly | 7.5910 | 1.215 | |
Affective CX (B) | Affective customer experience of customer i of the focal firm’s broadband services measured on a five-point Likert scale via a survey in December of each year from 2013 to 2016 (1 = very poor, 2 = poor, 3 = fair, 4 = good, 5 = very good).

Social class | Social class (low, medium, or high) that customer i belongs to at time t | Yearly | _ | _ | ||
Age | Age (in years) of customer i at time t | Yearly | 42.7308 | 19.9295 | ||
Householdsize | The number of family members of customer i at time t | Yearly | 2.9827 | .0015 | ||
Competitive Affective CX (M/B) | Competitive affective customer experience in mobile/broadband services measured in December of each year from 2013 to 2016 by computing the difference between the mobile/broadband affective customer experience of customer i perceived from the focal firm and the average score for affective customer experience in the mobile/broadband service category for the rest of the competing firms | Yearly | .0055/.0135 | .2334/.2387 | ||

-
The moderating role of relationship depth in the main effects of lock-in (H3). Lock-in helps to retain customers who have a weak relationship with the firm. However, with a deeper relationship, lock-in may backfire. Indeed, given high relationship depth, a binding contract could increase customer churn from 0.43% to 1.12% (Panel F of Fig. 2).
-
The moderating role of relationship depth in the main effects of affective customer experience (H4a–b) Delivering positive affective customer experience can effectively reduce customer churn, especially for customers who have weak relationships with the firm. However, for customers who have established deep relationships with the firm, a more nuanced perspective is required. Ensuring positive affective customer experience is necessary to maintain the established relationship. However, firms should be aware that the marginal effect of improving affective customer experience decreases as a deeper customer–firm relationship develops. Thus, for these customers, business managers should place the emphasis on ensuring an acceptable level of affective customer experience, allowing customers to rely on their confidence in assessing ongoing interactions. This emphasis should be mainly applied to the core category, since customers tend to be insensitive to affective customer experience perceived from other related categories.
-
The moderating role of relationship depth in the joint effects of lock-in and affective customer experience (H5a–b) Both lock-in and affective customer experience help firms to enhance customer retention. Intuitively, the more the better, and therefore one might suggest that firms should always implement the two strategies simultaneously. Nonetheless, our research shows that managers need to follow a timeline, and that doing so is critical for balancing the short-term and long-term financial consequences of customer retention strategies. From a long-term perspective, improving affective customer experience should be considered as the core strategy for firms. Happy customers have better retention rates and are less price-sensitive. In addition, happy customers tend to complain less, which reduces the stress on the firm’s operating infrastructure and helps to keep costs in check. Both prior academic research (e.g., Becker & Jaakkola, 2020; De Keyser et al., 2020; McColl-Kennedy et al., 2019) and business practice (Watermark Consulting, 2021) consistently highlight the importance of adopting a long-term approach in means dedicating efforts in improving affective customer experience. However, firms are not always able to provide excellent (or even acceptable) affective customer experience, and they may need time to improve the relevant internal processes. In the interim, lock-in mechanisms can be used. We thus argue that lock-in can serve as a stop-gap, providing firms with additional time to repair the affective customer experience before the expiration of a lock-in. Any decision to adopt such a strategy should take into account the firm’s objectives and resource availability, since economic incentives might be a drain on firm resources.
