Promoting Recycling: Private Values, Social Norms, and Economic Incentives
基于全美代表性家庭数据，研究发现个人环境价值观和亲环境行为规范显著促进塑料水瓶回收，而社会规范影响微弱；州回收法和瓶押金等经济激励政策效果突出，能将非回收者转变为积极回收者。
Evidence from a nationally representative sample of households illuminates the determinants of recycling behavior for plastic water bottles. Private values of the environment are influential in promoting recycling, as are personal norms for pro-environmental behavior. However, social norms with respect to the assessment of the household's recycling behaviors by others have little independent effect. Particularly influential are policies that create economic incentives to promote recycling either through state recycling laws that reduce the time and inconvenience costs of recycling or through bottle deposits. Effective policies can have a discontinuous effect at the individual level, transforming non-recyclers into avid recyclers.
