Consumer Search in Retail Gasoline Markets
利用汽油价格网站的日度网页流量数据直接衡量搜索强度，检验零售汽油市场中的消费者搜索行为，发现存在横截面和时间序列上的价格搜索证据。
This paper develops direct tests for search behavior in retail gasoline markets. We exploit a unique market‐level dataset that allows us to directly measure search intensity with daily web traffic data from a gasoline price reporting website and perfectly measure daily changes in price levels and dispersion. Our simple yet powerful tests provide strong evidence of both cross‐sectional and intertemporal price search.
