Abstract: To encourage strategic consumers to buy the short-life-cycle products in advance,the joint strategy models of advance selling and buy-back were established respectively to analyze retailer's advance price,buy-back price and optimal order quantity decisions for conventional products and new products.In the pre-sale of conventional products,changes in consumers'consumption psychology were common returning reasons,at which the partial buy-back policy achieved the highest profit.In the advance selling of new products,consumers would return if the products did not meet their expectation,at which the buy-back policy was not beneficial to retailer because it would increase the demand uncertainty and ordering decision difficulty.

Key words: conventional products, new products, strategic consumers, advance selling, buy-back policy, jointpricing, ordering decision
