Zooming In on Choice: How Do Consumers Search for Cameras Online?
利用详细的数据集，描述了消费者在购买数码相机前的在线搜索行为，发现平均搜索14次，早期搜索能预测最终购买，且搜索路径存在“锁定”效应。
We describe online consumers’ search behavior for differentiated durable goods using a data set that captures a detailed level of consumer search and attribute information for digital cameras. Consumers search extensively, engaging in 14 searches on average prior to purchase. Individual level search is confined to a small part of the attribute space. Early search is highly predictive of the characteristics of the camera eventually purchased. Search paths through the attribute space are state dependent and display “lock-in” as the search unfolds. Finally, the first-time discovery of the chosen alternative usually takes place toward the end of the search sequence. We discuss these and other findings in the context of optimal search strategies and discuss the prospects for consumer learning during search.
