Innovation is one of the most important issues in business research today. It has been studied in many independent research traditions. Our understanding and study of innovation can benefit from an integrative review of these research traditions. In so doing, we identify 16 topics relevant to marketing science, which we classify under five research fields:(More)

T study examines whether user-generated content (UGC) is related to stock market performance, which metric of UGC has the strongest relationship, and what the dynamics of the relationship are. We aggregate UGC from multiple websites over a four-year period across 6 markets and 15 firms. We derive multiple metrics of UGC and use multivariate time-series(More)
The product life cycle (PLC) is the result of multiple supply and demand forces. However, past research has focused primarily on the role of diffusion in driving the PLC. This study takes a step toward a broader theoretical perspective on the PLC by incorporating informational cascades and developing and testing many new hypotheses based on this theory. The(More)
The authors study how ad cues impact actual consumer behavior in new vs. well-established markets. They use theoretical insights from consumer information processing to argue that the same ad cues can have different effects on consumer behavior, depending on whether the market is new or old. They then test these hypotheses in the context of a toll-free(More)
The Internet has enabled consumers to make more informed decisions more conveniently with apparently more efficient price-clearing mechanisms than was available before its advent. One such mechanism is the name-yourown-price auction. The authors study the extent to which decisions made in such an auction are rational in relation to an economic model. The(More)
Despite extensive research on consumer innovativeness, the literature does not contain a parsimonious construct that has been validated for use across countries, demographics, and categories. This study attempts to fill this gap by studying consumer innovativeness across 15 major world economies. Significantly, the authors find that four negatively valenced(More)
T failure of firms in the face of technological change has been a topic of intense research and debate, spawning the theory (among others) of disruptive technologies. However, the theory suffers from circular definitions, inadequate empirical evidence, and lack of a predictive model. We develop a new schema to address these limitations. The schema generates(More)
