We assume that the durability of goods is provided exogenously, and that the marginal cost is independent of the durability. There is an infinite horizon, and firms choose the production level in every period. We obtain the following result. A firm that provides goods with less durability produces more goods in every period and can earn more profit than another if the quality of the secondhand goods or the marginal cost are sufficient low., 中尾武雄教授古稀記念論文集, Dedicated to Professor Takeo Nakao on his 70th birthday, Article, application/pdf},
