 note = {本稿では、生産される財が品質というよりも耐久性によって製品差別化されている複占市場を分析する。耐久性は外生的に与えられ、限界費用は耐久性とは無関係であるとする。無限期までを考え、企業は毎期価格を決定する。そこで以下の結果を得た。(1)中古価格が正である限り、両企業とも正の利潤を得る。(2)中古財の品質が十分に低いならば、耐久性に劣る財を生産する企業がより多くの利潤を得る。, This paper analyzes a duopoly market where products are differentiated by durability instead of quality. We assume that the durability of goods is given exogenously, and the marginal cost is independent of the durability. There is an infinite horizon and firms choose price in every period. We obtain the following results: (1) The firms earn positive profits as long as the price of the secondhand goods is positive. (2) The firm that provides goods with less durability can earn more profit than the other if the quality of the secondhand goods is sufficiently low., 論説(Article), application/pdf},
