摘要：Trade-in programs for electronics products, e.g., mobile phones, have been increasingly popular. These programs target at customers (we call them "bargainers") who seek to salvage or upgrade their old devices. There are two widely adopted trade-in options: trade-in-for-upgrade and trade-in-for-cash. In this paper, we consider a firm who offers both trade-in options, i.e., a hybrid trade-in program, to acquire old products, then refurbishes and resells them, together with  new product over a finite selling horizon. The bargainers choose which option to trade in their products while new customers decide whether to buy a new product or a refurbished one. When the selling price of new products is exogenous, we derive the optimal trade-in prices of old product and resale price of refurbished product. We show that the optimal trade-in and resale policies are of a threshold-type and trade-in-for-upgrade should be offered with a premium refund (compared to trade-in-for-cash) only in early periods of the selling horizon. We further consider two variants of the base model. In the first, the new product has a fixed amount of initial inventory and is not replenishable during the selling horizon. One different finding is that the firm may still offer a premium refund for trade-in-for-upgrade in the later periods of the selling horizon. In the second, the firm also sets the new product price. We show that when the customer sensitivity of product quality follows a uniform distribution, it is optimal for the firm to set the new product price at a constant level during the entire horizon, regardless of the refurbished product's inventory level. Finally, our  numerical results demonstrate that the hybrid trade-in program could generate significantly more profit than either upgrade-only or cash-only trade-in program.
