Abstract: To analyze the impact of consumers price reference effect on dynamic pricing strategies in closed-loop supply chains,the pricing strategies and profit allocation problems of a two-period closed loop supply chain system under centralized decision and three decentralized collection modes (manufacturer-collection,retailer-collection and third party-collection) with the consideration of price reference effect were discussed.The backward deduction method was utilized to obtain and compare the equilibrium solutions of decision variables in above four cases,and the variation trends of equilibrium solutions with price reference parameter were analyzed.The result showed that besides the centralized decision be the best of all,the third party-collection mode yielded the lowest collection rate and the worst system performance,whereas the relation between manufacturer-collection mode and retailer-collection mode depended on the values of remanufacturing cost savings and collection subsidies.Under centralized decision,as the price reference effect increased,both the two periods prices decreased and the optimal collection rate increased.When the price reference effect was greater than 0.6321,the whole channel profit decreased in the reference effect;on the contrary,when the price reference effect was smaller than 0.6321,the variation trend between channel profit and reference effect was related to the chosen parameters:if the collection scale parameter was lower than its threshold,the channel profit decreased in the reference effect,otherwise increased.Under three decentralized collection modes,the 1st-period price increased,the 2nd-period price decreased and the collection rate decreased in the price reference effect.However,the channel members and the whole closed-loop supply chain could benefit from the reference effect.
