【摘要】

Peer-to-peer (P2P) resale markets have grown rapidly in recent years along with online retailing. While most of online retailing platforms focus on selling new products, P2P resale platforms create a new venue for millions of used-product owners (i.e., holders) to resell their used products when updating to new ones. However, these P2P resale markets could considerably encroach onto the existing demand of new-product sellers. To explore the impact of P2P resale markets on new-product sellers, we consider a Cournot competition model with two competing firms manufacturing and selling substitutable new products and a P2P resale market. When the firms are homogeneous in production costs, our analysis first corroborates the firms' concern on the negative demand encroachment effect of the P2P resale market; as a result, both firms are worse off with the P2P resale market than without, specifically if the proportion of holders in the market is high and the discount rate of the used product is low. Although the P2P resale market attracts away those consumers with lower willingness-to-pay(WTP), it also releases some holders to purchase new products and, more importantly, allows the firms to price higher for remaining consumers with higher WTP. Therefore, if the proportion of holders in the market is low enough and the discount rate of the used product is high, both firms can instead be better off with the presence of the P2P resale market. Furthermore, when the firms are heterogeneous in production costs, we observe another unconventional outcome (i.e., the weaker's benefit) that the more cost-inefficient firm is more likely to benefit from the presence of the P2P resale market. Moreover, the presence of the P2P resale market can conditionally lead to more environmental impact and less consumer welfare. These results are robust against an endogenous commission rate of the P2P resale market or the number of competing firms.
