This paper analyses the behaviour of banks’ customers when a new technology (internet banking) is introduced. The determinants of consumer adoption of internet banking are characterised using survey data from Korea in both static and dynamic framework. There is evidence that adoption of internet banking is influenced by sex, age, marital status, degree of exposure to internet banking, and the characteristics of the banks. A duration analysis shows no evidence of first mover advantage (order effects) in internet banking whilst the largest bank (rank effects) in commercial banking remains dominant in internet banking. The results imply that the internet banking adoption is dominated by social norm effects.
