摘要:AbstractUnder the recent severe financial situation, it is more important that central and local governments justify their public investments than ever. Cost-benefit analysis (CBA) is often used for this problem. However, CBA has not been done on public library services in Japan. The aim of this study is to conduct double-bounded dichotomous choice CVM (contingent valuation method) and to validate applicability and effectiveness of this method. The result shows that respondents are willing to pay about 350 JPY per library-use on average. Moreover, household income and frequency of public library use significantly affect their willingness to pay.
