主 题：Games of Supplier Encroachment Channel Selection and E-tailer's Information Sharing
内 容：We consider an e-tailer's upstream supplier who wants to encroach into retailing to earn additional revenue. The supplier needs to decide whether to enter the retail market by either selling to consumers on the e-tailer's platform by paying commission fees (agency encroachment) or opening an independent online/offline retail store (direct encroachment). The e-tailer has private demand information and decides whether to share it with the supplier. Two leadership scenarios---the supplier-leads (i.e., the supplier selects the channel before the e-tailer decides whether to share information) and the e-tailer-leads (i.e., the supplier selects the channel after the e-tailer decides whether to share information)---are examined. Our main findings are as follows. First, we show that the e-tailer has no incentive to share information under no encroachment and direct encroachment. Interestingly, this result holds in both leadership scenarios. Second, a medium commission rate gives rise to an equilibrium of agency encroachment with information sharing by the e-tailer. This equilibrium is more likely to sustain in the supplier-leads scenario than in the e-tailer-leads scenario. Third, agency encroachment brings the seller the highest sales volume (at retail in the encroaching channel plus on wholesale to the e-tailer) when the two parties compete in quantity while direct encroachment does so for a price competition. Fourth, supplier encroachment always improves consumer surplus, but it is not necessarily welfare-improving. Last, we find that the e-tailer is more willing to share information to induce the supplier to encroach through his agency channel if he has a significant selling cost advantage over the supplier or can endogenously determine the commission rate.
