Companies are often clueless about when their consumers will purchase again. New research by Evşen Korkmaz from Rotterdam School of Management, Erasmus University (RSM) will help businesses determine how much time and effort individual customers are worth investing in. Korkmaz reveals that by using existing customer base analysis models but extending their analytic capabilities, companies can predict the specific interests, and purchasing behaviour of customers at an early stage in order to develop individual marketing strategies.

When will a customer purchase again?

Recent years have seen many advances in quantitative models in the marketing literature. These advances enable model building for a better understanding of customer purchase behaviour and customer heterogeneity in a way for firms to develop optimal targeting and pricing strategies. Still, it has been observed that not many of the advanced models have found their way into business practice. With her dissertation Understanding heterogeneity in hidden drivers of customer purchase behaviourEvşen Korkmaz bridges the gap between advanced models and their business applications by systematically extending the use of models.

Sometimes a company hasn’t heard from a particular customer for a while, due to matters such as a changing family situation, holiday leave, or the loss of interest in your product. While a customer does not often share this information, companies should know whether that customer is still active and worth approaching. To map this out, businesses use probabilistic models that utilise customer data from the past to predict their future behaviour. However, in her dissertation, Korkmaz exposes that much more can be read with these existing models.

Korkmaz focuses on probabilistic customer base analysis models that deal with understanding customer heterogeneity and predicting customer behaviour. These models specify a customer's transaction and defection processes under a non-contractual setting. Through this study, she shows that the timing of the next purchase for each customer can be predicted using these models. This information can help a company decide whether the customer is worth investing time, money and effort in.

Building two new models, Korkmaz interprets customer heterogeneity in a more flexible and insightful way. As a result, managers can obtain a refined segmentation. Customers are no longer analysed as one heterogeneous group, but rather as several heterogeneous groups, so-called customer segments, so that one can analyse within and across heterogeneity, for whom both individual and segment-specific marketing techniques can be determined.

Businesses can learn from this research how to get a hold of more – and more accurate – information on their customer’s behaviour by using data they already have.

Recent years have seen many advances in quantitative models in the marketing literature. Even though these advances enable model building for a better understanding of customer purchase behavior and customer heterogeneity in a way that firms can develop optimal targeting and pricing strategies, it has been observed that not many of the advanced models have found their way into business practice. This thesis aims to bridge the gap between advanced models and their business applications by systematically extending the use of models. Korkmaz first focuses on probabilistic customer base analysis models that deal with understanding customer heterogeneity and predicting customer behaviour. These models specify a customer's transaction and defection processes under a non-contractual setting. Through this study, she shows that the timing of the next purchase for each customer can be predicted using these models. Korkmaz also extends them by modeling customer heterogeneity in a more flexible and insightful way. As a result, managers can obtain a refined segmentation. Based on the customer heterogeneity insights, Korkmaz then focuses on pricing strategies for online retailers who derive their revenues from delivery fees and sales. In order to come up with optimal pricing strategies for delivery fees, she uses ideas from the two-part tariff literature.

Given the time and costs associated with implementing advanced models and theories in managerial practice, marketing executives need to be convinced  to implement advanced models by clearly demonstrating the contributions of such models. Korkmaz’ study serves as a step toward bridging advanced models and business practice by empirically demonstrating their extended contributions.
