 note = {This paper criticizes the conventional wisdom that a second-hand market may weaken the incentive for durable-goods monopolist to develop the new products that is improved in quality.  The analysis will be undertaken by distinguishing the products according to its value of second-use.  In the case of high value of second-use (such as cars and PCs), the second-hand market may assure socially desirable investment in the development of the new products for wide range of quality change.  This is because a second-hand market can help the monopolist screen the demand of consumers with higher valuation for the products and extract-perfectly consumers’ surplus from the new product introduction.  On the other hand, if the products don’t possess the value of second-use (such as video games, books and music CDs), the profitability of the sales of the new products is not affected by the second-hand market, neither is the investment in the development of these products.},
