Toward a unified theory of consumer acceptance technology

In the last few decades, scholars and practitioners have increasingly tried to understand the factors that influence technology acceptance. Theories and models developed by scholars have tended to focus on the role of cognition and have rarely included affect. The few studies that have incorporated affect have tended to measure a single emotion rather than modeling it comprehensively. This research addresses that inadequacy in our understanding of technology adoption by merging two previously unrelated models: TAM (the Technology Acceptance Model) and PAD (the Pleasure, Arousal, and Dominance paradigm of affect). This study also examines an enhanced view of cognition. The product of this unified theoretical framework is referred to as the Consumer Acceptance of Technology (CAT) model. The results of a test using structural equation modeling provide empirical support for the model. Overall, the CAT model explains over 50% of the variance in consumer adoption intentions, a considerable increase compared to TAM. These findings suggest that substantial improvement in the prediction of technology adoption decisions is possible by use of this model with its integration of affect and cognition. © 2007 Wiley Periodicals, Inc.     

Marketing,market growth,and endogenous growth theory: An inquiry into the causes of market growth

Market growth plays a central role in virtually all strategic marketing models developed in the past 30 years. Although marketing scholars seem implicitly to assume that marketing efforts contribute in some way to market growth, market growth per se remains a conceptual black box in marketing. Using new developments in endogenous growth theory, this article explores the link between marketing actions and market growth. In particular, the authors develop a conceptual model arguing that the effect of endogenous actions on market growth is mediated by knowledge creation, matching, and diffusion. Propositions are proposed to guide future research. The authors discuss the implications for marketing strategy at both business discipline and public policy levels.

The role of social influence on adoption of high tech innovations: The moderating effect of public/private consumption

As technological innovations have become an integral part of the world economy in recent decades, predicting acceptance of those products has become a major goal of many researchers in academia and industry. The main objective of this study is to examine the role of social influence and the moderating effect of a product's public/private status on consumers' intended adoption of high-tech innovations. The results indicate that both social influence and adoption attitude have positive effects on consumer intention to adopt an innovation. Specifically, the effect of social influence on adoption intention is fully mediated by consumer attitude. Further, the relationship between social influence and adoption intention is stronger when an innovation is publicly consumed rather than privately consumed. Implications and future research directions are discussed.
