OPTIMALITY OF RECYCLING AND THE LOCATION OF A RECYCLING CENTER
研究即使居民不偏好回收、垃圾填埋空间充足且回收物市场价格为零时，地方政府仍可通过合理选址回收中心来降低总废物管理成本，使回收成为最优选择，且城市规模越大回收越可能最优。
ABSTRACT. Consider a community investigating the integration of recycling into its waste management program. Even if (1) the county's citizens do not gain utility from recycling, (2) landfill space is plentiful, and (3) the market price for recyclables is zero, recycling can still be optimal for a local government. By determining the relationship between the amount of recycling and the location of a recycling center, conditions are identified under which recycling will reduce total waste management costs enough that municipal recycling will be optimal. In addition, it is shown that the likelihood of municipal recycling increases with the size of the city.
