In this paper, we study consumer's characteristics leading to shopping and buying over the Internet. Based on a survey data, we apply the multinomial logit model for following three discrete choices: those who have the experience of internet purchases, those who did window shopping only, and those who have none of the experiences. The results are as follows: Demographic variables such as schooling, marital status, and occupational groups are shown to affect the probability of internet buying. Also likely to buy over the internet are those who frequently access to the Internet, have longer experiences of use, and are subscribed to broadband services. Internet buying is also highly correlated with transactions-related activities on the Internet but not to entertainment or non-transaction information gathering activities. Next, those who use the Internet only for window shopping have similar characteristics to the Internet buyers in general, but the former tend to be new users and are likely to have experiences in relatively basic Internet activities. On the other hand, our results indicate that marketing over the Internet is not quite as effective as over the television.
