This research aims to enhance our knowledge of Internet purchase behavior by proposing a new model which draws from three disciplines: consumer behavior, decision analysis and IS. A research methodology has been designed to capture the dynamic process that Internet shoppers follow when they are engaged in a shopping experience and the influences of their interactions with the environment on their behavior. Data from an Internet panel data provider, video recording sessions and questionnaires will be collected to capture the purchase behavior process and establish the contextual factors and the possibilities of cross-channel behavior in the three different sectors of banking, groceries and mobile phones. The proposed model will be revised based on the results of our study. The theoretical and empirical results will inform the three literatures of this study. Companies will also be able to devise winning strategies by better understanding their consumers’ Internet shopping behavior.
