主讲内容：
With the rapid development of live-streaming e-commerce, it has been increasingly common for firms to collaborate with live-streamers (e.g., online influencers, celebrities, or key opinion leaders) to promote and sell their products via live broadcasting shows. In addition to the products and reputation of the live-streamers, the success of a live-streaming show largely depends on the effort the live-streamers devoted in attracting fans and promoting products. Hence, in order to improve the live-show sales, in addition to the sales commissions, the live-streaming agreement signed between the seller and live-streamer sometimes specifies a minimal sales volume, which represents the sales commitment the live-streamer makes. In this paper, we study the impact of such commitment on the performance of a supply chain where a seller sells its product via a live-streamer. The live-streamer determines the effort level that affects random demand at the live-show while the seller determines the stocking level to be prepared prior to the live-show. We solve and compare their optimal decisions and corresponding expected profits for the scenarios without and with the live-streamer's sales commitment. Without sales commitment, the live-streamer's optimal effort and profit first increase and then decrease in the commission rate; while the seller's optimal stocking level and profit could be decreasing or first increasing and then decreasing in the commission rate, depending on the popularity of the live-streamer. With sales commitment, if the live-streamer indeed commits, she spends more effort and commits more while the seller stocks more when the commission rate increases. Compared between these two scenarios, the live-streamer is always better off whereas the seller would also be better off if the live-streamer's penalty of not fulfilling commitment is high or the commission rate is relatively low. Finally, we propose a set of commitment-based contracts to coordinate decisions of the seller and the live-streamer that maximize their overall profit.
