Critical constructs for analyzing ebusinesses investment, user experience and revenue models

Examines issues related to the successes and failures of Internet businesses. Recent literature has stressed the value of microeconomic models of markets to analyze ebusiness models and strategy. The concepts of transaction costs, switching costs, network externalities and product versioning are especially useful in understanding business strategy in the new information economy. These concepts are reviewed and analyzed. A deeper assessment of Internetbased businesses, both successes and failures, reveals a number of other constructs that are relevant for analysis, viz. infrastructure investment models, user experience models and models of revenue generation. These constructs reveal the inherent complexity of the electronic medium for conducting business and point to the subtle issues that determine success or failure. Case studies and examples are used to illustrate the usefulness of these constructs.
