题目: Streaming Customers in Live Stream Commerce: Identifying Lifts from Sales Pitches
摘要: Live stream commerce is a trending marketing practice where customers watch broadcasters' online sales presentations in real time and make purchases quickly in the showroom. A top broadcaster in China can realize about one million dollars in sales during a three-hour live show on a typical day. However, skepticism arises on its overall effectiveness to the brand. The live stream may cannibalize sales volumes from other channels, and high commission fees and deep discounts may even shrink the margin. This paper identifies the net effect of the sales pitch by top broadcasters using customers' streaming data from a leading live stream platform in China. Broadcasters launch a sequence of products during one show and sometimes have intermission periods during two products. What customers see depends on their time of entering the showroom. We compare two groups of customers, one entering the showroom during a product interval and the other during its follow-up intermission, to examine the net effect of the sales pitch by broadcasters. We find that customers increase their tendencies of product-page browsing by 1.92% (relative to 9.11% for those who do not see the live sales pitch) and their purchase likelihood by 0.88% (relative to 0.66%). Effects are more pronounced for low-involvement and hedonic products, and customers aged between 30 and 50 are mostly affected. Further analysis suggests a positive intensive margin, as customers entering earlier convert more within a product period.
