Social norms have been claimed to influence customer retention when the social network the customer engages with is well aware of a customer’s use of the product or service. This research investigates whether social norms will also influence customer retention for services that are used so infrequently that the social network the customer engages with is not aware that the customer has the product or service. The specific services investigated are also impacted by the fact that the customers themselves are not entirely certain as to their individual need of the product, namely credence goods. The aim of this research is to provide a profile of a customer that would be more influenced by social norms; which knowledge would allow organisations to target specific customers. Using the Mann-Whitney and Kruskal-Wallis tests, hypotheses were tested by analysing questionnaire feedback data on 100 active insurance customers and 100 inactive insurance customers from within the South African financial services market. Empirical support for the effect of social norms on customer retention of credence goods is found. Empirical proof that females are more influenced by social norms than males was found as well as the link between culture value orientation to social norms. In this research a link between a customer’s age to social norm influence was not found. / Dissertation (MBA)--University of Pretoria, 2013. / ccgibs2014 / Gordon Institute of Business Science (GIBS) / MBA / Unrestricted

Digital advertising has seen dramatic growth over the last decade. Total digital ad spending in the US has increased 6 times between 2010 and 2020, from $26 billion to $152 billion(eMarketer). This impressive development has in turn sparked a huge stream of literature studying all the different aspects of advertising in the digital media. My dissertation contributes to this literature via two essays. In the first essay, I consider a very important topic of ad blocking, that in the recent years has become a significant threat to advertising supported content. With a specific focus on consumer and total welfare, I show the detrimental role of the adblockers’ current revenue model in decreasing content quality, consumer surplus and total welfare. In the second essay, I study demand learning in digital advertising markets, where firms learn over time how their advertising campaigns impact consumer demand by using their advertising campaign outcomes in earlier periods. By developing an analytic model, I demonstrate in several scenarios, such as monopoly and competition, that learning has an ambiguous effect on the key market parameters and, in particular, on the equilibrium advertising and quantities.
