在一个准实验环境中使用
机器学习方法,我研究了引入废物价格--家庭未分类废物处理的单位价格--对废物需求和社会福利的异质性影响。首先,使用一个价格和可观察到的差异很大的意大利城市的独特小组,我表明废物需求是非线性的。我发现有证据表明,在低价格时弹性不变,在高价格时弹性增加,这是由政策前的收入效应和浪费习惯驱动的。其次,我估计政策对污染和城市管理成本的影响,并计算每个城市的总体社会成本节约。在采用三年后,当废物价格导致显著避免废物时,所有城市的社会福利效果都是积极的。

英文摘要:
  Using machine learning methods in a quasi-experimental setting, I study the heterogeneous effects of introducing waste prices -- unit prices on household unsorted waste disposal -- on waste demands and social welfare. First, using a unique panel of Italian municipalities with large variation in prices and observables, I show that waste demands are nonlinear. I find evidence of constant elasticities at low prices, and increasing elasticities at high prices driven by income effects and waste habits before policy. Second, I estimate policy impacts on pollution and municipal management costs, and compute the overall social cost savings for each municipality. Social welfare effects are positive for all municipalities after three years of adoption, when waste prices cause significant waste avoidance.
