RESEARCH

The Welfare Effects of Summary Information: Taobao’s Golden Seller Certification

Abstract: Consumer-based rating systems and reputation signals have been main sources of information on product quality and seller performance in online markets. However, it is time consuming to sifting through all the information. This raises an important question: if someone has evaluated all the reviews, summarized all the available information and compiled it into a simple badge, will consumers value such easily accessible information in decision making? This paper studies the valuation of Golden Seller certification, a badge that conveys such summary information, using data collected from the smart phone markets on Taobao. We use a structural model to evaluate the

overall effects of the Golden Seller certification on consumer welfare and seller profits. Our results reveal that the Golden Sellers charge a relatively lower price, but have a significant higher sales volume. Additionally, our demand estimation and counterfactual simulation suggest that consumer welfare improves because of the new information as well as the added convenience and accessibility of the existing information conveyed in the badge. Meanwhile, Golden Sellers, or high-quality sellers, benefit from the certification substantially while the other sellers are only slightly worse off. These results suggest that the certification enhances market efficiency and expands market.

Price and Quality Effects of Code Sharing Agreements: Evidence from United Airlines/US Airways

Abstract: Past studies of airline alliance have focused on price effects, while very limited empirical evidence was shown on the service quality. This paper investigates the price and quality effects of the codesharing agreements between United Airlines (UA) and US Airways (US) on ticket level. Using a difference-in-difference-in-difference model, this study finds that market fares in UA/US codesharing markets on average decrease relative to the non-codesharing markets. Further, there is an incremental negative effect on codesharing tickets, which is mainly driven by the virtual codeshare. However, the evidence on service quality in terms of connection is very interesting. The quality in UA/US codesharing markets on average declines relative to the non-codesharing markets. Moreover, regardless of the codesharing type, the alliance has a significantly negative effect on service quality. The passengers of traditional codeshared flights are harmed most by the alliance due to both relatively higher market fare and a longer distance traveled.
