Word of mouth (WOM) is an important component of a complex and dynamic marketplace environment, and as such, WOM research is best undertaken as part of a holistic research program. Five principles describing the operation of WOM are discussed, supported by data, and examples drawn from recent research studies. Complexity science modeling is introduced as an effective method for simulating the r...

This paper investigates the design and application of write-once memory (WOM) codes for flash memory storage. Using ideas from Merkx [1], we present a construction of WOM codes based on finite Euclidean geometries over F2. This construction yields WOM codes with new parameters and provides insight into the criterion that incidence structures should satisfy to give rise to good codes. We also an...

Companies are encouraging and incentivizing contributors of online word-of-mouth (WOM) through gamification elements such as badges, mayorships, points, and such. We study how gamification elements, which capture and signal contributors’ accumulated expertise, affect consumers’ perception of contributors’ knowledge, and therefore the perceived effectiveness of their contributed WOM. We focus on...

Design/methodology/approach: Using a survey instrument, we empirically test the conceptual model of De Matos and Rossi (2008). Findings: We find support for the model and find satisfaction, commitment, loyalty, trust, perceived value and quality to b...

The authors study the effects of word-of-mouth (WOM) marketing on member growth at an Internet social networking site. Because such sites track the electronic invitations sent out by existing members, outbound WOM may be precisely tallied daily and then linked to the number of new members joining the site (signups). To handle the potential endogeneity among WOM, new signups, and traditional mar...

Free sampling of information goods has become a common business practice in expectation of reducing consumers’ uncertainty of product quality and helping product diffusion, yet receiving limited investigation of how consumers process free sampling and online word-of-mouth (WOM) and its consequences on retail sales. In this research, we examine the impact of free sampling of information goods on...

This paper investigates the effects of word of mouth (WOM) through microblogging and third-party platforms on the box office revenue of a movie and the moderating role of movie popularity. The study uses a two-year panel data set of 147 movies, tweets from 120 thousand randomly selected users of Sina Weibo, and reviews from Douban.com discussing these movies in their release period and finds th...

In this research, we investigate how television advertising drives online word-of-mouth (WOM). We first explore if television advertising (1) affects online WOM about the brand advertised and (2) associates with changes in online WOM about the program in which the advertisement airs. We further examine if the media context in which the advertisement appears – the television program – impacts th...

Consumers who had memorable shopping experiences (i.e., special promotions or exceptional services) tend to resort to word-of-mouth to tell significant others in their social network about those experiences. The study aims to investigate the role of social networks in the adoption and dissemination of e-WOM arguments. The study’s objectives are three-fold.: First, the study examines the effects...
