Abstract:
Like any other Information Communication Technology (ICT) solution, E-shopping alters shopping trip patterns in a city. Product internet searching is another ICT solution which affects shopping trip patterns in a city. At the first stage, by producing ordinal regression models, this study explores all factors which are effective in adoption and frequency of product internet searching and e-shopping. In the next step, rather than pre-imposing restrictive assumptions regarding dependence, this study determines the structure of dependency between product internet searching and e-shopping with two (adoption and frequency) joint models by implementing the copula-based approach. This study relies on data gathered from students of Tehran in 2012 which provides several different individual demographics, shopping behaviors, internet usage, and ttitudinal/behavioral characteristics. Results of this study indicate the existence of a subtle positive dependence between the adoption of these two ICT choices. On the other hand, strong positive and asymmetric dependence has been observed for the frequency of these two ICT choices
