With the increasing popularity of online retailing, this research investigates the alternative online operation strategies regarding commission price when selling through online platforms. We exploit a triadic network setting that consists of one online platform firm and two competing vendors and examine the strategic choice of the involved parties to effectively compete in the marketplace. We develop game models for alternative commission pricing strategies and obtain the equilibrium solutions. Through a comparison of equilibrium solutions, our analysis reveals that alternative commission pricing strategies lead to different economic results for the online platform and the two vendors individually and collectively. While vendors can take necessary actions (e.g., an additional fee for an exclusive pricing right) to maximize their own benefit, competing vendors can also respond to their rival's strategic choice to minimize the negative impact of the deal reached by the other two parties. Our findings also suggest that the exclusive pricing right that the lead vendor tried to secure results in a higher commission fee paid to the online platform. Through modelling strategic behavior and consequential economic results in the setting of a triad network, our research also responds to the proposition that structural and behavioral approaches represent incommensurable ideas, and we show that a combined theoretical strategy appears well-adapted to the complex realities of interfirm networks.
