| 要旨 | We examine a hybrid supply chain in which a manufacturer distributes its product both directly to consumers via an online channel and indirectly through its affiliated retailer. Contract terms are determined through Nash bargaining. The manufacturer and the retailer make strategic upfront investments that increase the consumers’ willingness to pay. We focus on the parties’ asymmetric bargaining positions: the retailer can only profit when bargaining reaches an agreement while the manufacturer can still offer its product if bargaining fails. As a consequence, we find that the investments have opposite effects on the surplus that is shared between the supply chain partners. The retailer’s investment always increases the trade surplus, whereas the manufacturer’s investment reduces the trade surplus. This gives rise to counterintuitive results. The parties’ profits are reduced, if (1) the consumers’ common willingness to pay for the product increases, (2) the consumers’ “dislike” of online purchases from the manufacturer decreases, and (3) both firms’ investment efficiency increases. Our results hold under linear and nonlinear demands, under quantity and price competition, and with a linear and nonlinear supply contract. We further find that an increase in the manufacturer’s bargaining power can actually reduce the manufacturer’s profit, increase the retailer’s profit, but hurt the supply chain. |
