Longer duration of extended warranty at a lower price attracts more customers to buy through the retail channel and hence enhances the retailer's profit margin. Two different coordination contract mechanisms, namely, all unit quantity discount along with franchise fee, and revenue sharing contracts are proposed to resolve channel conflict and asymmetric Nash bargaining product is used for a particular profit split.
