考虑产品质量差异和二手市场时以旧换新对双寡头竞争的影响
Impacts of trade-in program on duopoly competition with product quality differentiation and secondhand market
摘要
Abstract
Considering the existence of the Secondhand market and the implementation of trade-in program,the competition models between two manufacturers who produce the same products at various qualities are developed by the Nash game,and the impacts of the trade-in program from the perspectives of the demands,profits,marginal profits of manufacturers and the net costs of consumers are investigated.It finds that the trade-in program has different impacts when it is implemented by different manufacturers.When the low-quality manufacturer implements the program,it is always beneficial to himself and consumers but harmful to the high-quality manufacturer.However,when the program is implemented by the high-quality manufacturer,it can be beneficial to the lowquality manufacturer as well as to the implementer but harrmful to consumers if the transaction cost of the consumer selling the used product in the secondhand market is low enough.Furthermore,with the increase in transaction cost,it also becomes harmful to the low-quality manufacturer and beneficial to consumers,which is the same as in the case that the low-quality manufacturer implements the trade-in program.The impacts of related parameters on the demands,marginal profits of manufacturers and the net costs of consumers are also analyzed.关键词
