摘要👨🏿‍💻：Several brand name companies have launched online peer-to-peer (P2P) platforms to support their customers to post, sell and buy their used  goods.  These P2P platforms serve as redistribution/secondhand markets where used or pre-owned goods are passed on from someone who does not want them to someone who does want them.  This is another alternative to the more common “reduce, reuse, recycle, repair" methods of dealing with waste.  For this reason, these firms typically publicize their campaigns as ``Go Green" programs.  However, as commonly perceived, secondhand markets would cannibalize the sales of a firm’s new products and thus compromises its financials. Hence, we aim to address two research questions here:  will actions of supporting customers to sell used goods through secondhand markets 1) enhance firm profits and/or 2) be greener than not supporting?  If a firm can benefit from more active secondhand trading, then a “Go Green” program will most likely lead to financial sustainability and hence the firm’s long-term voluntary commitment to such effort. To address these issues, we consider a stylized model in which selling and buying used goods is costless (i.e., of zero transaction cost). We determine when supporting resale of used goods is both environmentally friendlier and more profitable and when only one of the two goals can be achieved.
