The Impact of the Internet on Information Search for Automobiles
利用1990年和2000年汽车购买者调查数据，研究互联网作为汽车信息来源的使用决定因素、对其他信息来源的影响以及对总搜索努力的影响。
Using data from surveys of automobile buyers collected in 1990 and 2000 in a natural experiment setting, the authors study the determinants of use of the Internet as a source of information on automobiles, its impact on the use of other sources, and its impact on total search effort. The results indicate that the Internet draws attention in approximately the same proportion from other sources. The results also show that those who use the Internet to search for automobiles are younger and more educated and search more in general. However, the analysis also indicates that they would have searched even more if the Internet had not been present.
