The effects of variety and bundling on choice and satisfaction: Applications to new telecommunication and media services

The purpose of this working paper is twofold; 1)to review consumer behavior literature on how assortment variety and bundling influence choice related variables, and 2)to apply this review on an analysis of telecommunication and new services. Literature related to the characteristics of assortment/bundle, perception of the assortment/bundle, perception of the choice situation, choice, perception of the choice, and experience with the chosen option is reviewed with focus on assortment and bundling. The review is based on an open literature search using keywords as “assortment size”, “assortment variety”, “bundling” and “unbundling” in databases as ISI and Ebsco. In addition, manual reviews of references used in the articles revealed from the databases have also been used to make sure we cover as many relevant articles as possible. The articles reviewed are briefly summarized in table 1 (assortment studies) and table 2 (bundling studies).

Based on the literature reviewed, the results revealed are applied in a theoretical analysis of the effects of variety and bundling on choice- and post-choice related variables in new telecommunication and media services. Six services are discussed; traditional telephony and broadband services, mobile internet services and applications, services in heterogeneous access networks, multiplay services, TV-channel network services, and online video services. The analyses focus on potential effects of assortment variety and bundling on choice and post choice related variables for each of the six services. Because regulatory authorities typically use variety to stimulate efficient competition, some regulatory issues of relevance for each of the six services are also briefly discussed.

The main results from the general consumer literature review on variety and bundling is summarized. A brief summary of what seems to be the most relevant issues related to variety, bundling, and regulatory actions for the six telecommunication and media services analyzed is also presented. The review of the literature and the analyses of the six services show a significant need for research on how variety and bundling influence choice and choice related variables. A discussion of potential routes for future research together with a preliminary draft of a research model closes the discussion of this working paper.
