  1. Understanding & Predicting E-commerce Adoption: An Extension of the Theory of Planned Behavior(MIS Quarterly March 2006) Presented by: Yasmine Makram

  2. Objective This paper aims to: • shed light on the phenomenon of consumer adoption of B2C e-commerce using an extended version of the Theory of Planned Behaviour (TPB). • It draws upon theories from: IS, social psychology, marketing, and economics to propose, operationalize, and empirically examine a comprehensive model that explains & predicts 2 key online consumer behaviours: • Getting information • Purchasing products

  3. Definitions • Business-to-consumer (B2C) e-commerce is: “the activity in which consumers get information and purchase products using Internet technology” • E-commerce adoption is an “instance of IT acceptance and use within a setting that combines technology adoption with marketing elements, and it thus requires distinct theorization within the information systems literature.” • Getting information is an: “ activity intrinsic to the IT since the Web system itself presents the product information.” • Product purchasing is: “a task extrinsic to the IT since the Web system primarily provides the means to achieve the purchase.”

  4. What is different about e-commerce? • spatial & temporal separation between consumers and Web vendors • personal information can be easily collected, processed, & exploited by multiple parties not directly linked to the transaction. • consumers must actively engage in extensive IT use when interacting with a vendor’s website. • concerns about the reliability of the open Internet infrastructure that Web vendors employ to interface with consumers.

  5. The Theory of Planned Behavior (TPB)

  6. Proposed Extension of TPB

  7. Comparison

  8. Definitions Attitude:desirability of using a website to get information & purchase products from a Web vendor, respectively. Subjective Norm: perceptions of whether these two behaviours are accepted, encouraged, & implemented by the consumer’s circle of influence Self Efficacy:describes consumers’ judgments of their own capabilities to get product information & purchase products online. Controllability:consumers’ perceptions of whether getting information & purchasing products online is completely up to them because of the availability of resources and opportunities.

  9. Implications for Information Systems The set of accessible beliefs identified in this study was empirically shown to draw either from the: • IT adoption and use literature: (ex. perceived usefulness, perceived ease of use, download delay, navigability) or • the domain of IS (ex. trust, information protection, user skills), confirming the increasingly important role of IT in online consumer behaviour.

  10. Implications for Information Systems Since: online consumers are intrinsically active users of IT & IT considerations take center stage. Therefore: IT-related variables have become at least as important as traditional factors in predicting consumer behaviour on the Internet.

  11. Implications for Information Systems Rather than viewing e-commerce as a marketing issueinfluenced by IT use it is perhaps more accurate to view e-commerce as an IS phenomenon where an IT user interacts with a complex IT system. (This system includes not only a website, but also the supporting services and the people and procedures behind those services.)

  12. Implications for Information Systems An IS view would not only help better understand B2C e-commerce, but it may also shed light on how marketing, economic,& other factorsintegrate with IS concepts to better explain other complex IT phenomena.
