Municipal governments have attempted to reduce waste disposal and increase recycling rates in Japan. However, it is difficult to get full cooperation from residents. Using experiments in which residents are given an opportunity to choose the components of the waste management system (choice experiments), we measure the cost of each characteristic of the waste collection services. The estimation result reveals that there are trade-offs between the risk, payments, and handling costs. The marginal loss in utility revenues from an increase in the types of waste being separated is almost 200 yen (US$ 1.74) and a 1% increase in the recycling rate raises the cost of service by 53 yen (US$ 0.46). In addition, the results show the need for communications about risks between municipal authorities and residents.
日本的市政府一直在努力减少垃圾处理量并提高回收率。然而,很难获得居民的全面合作。通过让居民有机会选择垃圾管理系统的组成部分的实验(选择实验),我们测量了垃圾收集服务各特征的成本。估计结果表明,在风险、费用和处理成本之间存在权衡。垃圾分类种类增加导致的效用收入边际损失约为200日元(1.74美元),回收率提高1%会使服务成本增加53日元(0.46美元)。此外,结果表明市政当局与居民之间需要就风险进行沟通。
