Abstract: We consider product counterfeiting on a customer-to-customer platform that provides an inspection service. We develop a two-stage game-theoretical model. In the first stage, the platform designs a contract specifying commission and penalty fees. In the second stage, a seller signals his product authenticity by setting a price and a buyer decides whether to purchase it. This results in a contract design problem that governs a signaling game. We find that the effect of inspection is beyond merely detecting counterfeits. The inspection, even an imperfect one, changes the signaling game's structure and incentivizes the seller who likely has an authentic product to sell through the platform. This can only be achieved by carefully choosing the commission and penalty fees. Interestingly, a higher platform's expected profit does not imply a higher price or commission fee in equilibrium. Under some mild conditions, the optimal commission increases but the optimal penalty decreases as the platform’s inspection capability improves.
