Internet Car Retailing
研究了互联网汽车推荐服务对加州汽车经销商定价的影响，发现使用该服务的消费者平均支付价格降低2%，相当于每辆车节省450美元。
We investigate the effect of Internet car referral services on dealer pricing of automobiles in California. Customers of an online service pay on average 2% less for their car ($450 for the average car). 25% of the savings come from purchasing at low‐price dealerships affiliated with the online service. The remaining 75% stem from information provision by the online service, bargaining by the service on behalf of consumers, and cost efficiencies. A consumer receiving the mean online price does better than 65% of offline consumers, conditional on the car being purchased.
