气候经济学中的家庭作业：家庭生产、环境偏好与气候政策
Homework in Climate Economics: Household Production, Environmental Preferences, and Climate Policy
摘要
Household energy use accounts for approximately one third of U.S. emissions. Guided by a new survey, we develop a quantitative model in which households differ in income and their desire to reduce their emissions. Our analysis of cost-minimizing subsidies for clean equipment, such as electric vehicles and heat pumps, and residential solar yields three insights. First, solar receives the highest subsidy rate and accounts for over one third of abatement, reflecting its complementarities with clean equipment. Second, restricting subsidy eligibility to lower-income households generates only small cost savings. Third, without environmental preferences, household emissions would be over 15 percent higher.
中文摘要
家庭能源使用约占美国排放的三分之一。在一项新调查的指导下，我们构建了一个定量模型，其中家庭在收入和减少自身排放的意愿方面存在差异。我们对清洁设备（如电动汽车和热泵）及住宅太阳能的成本最小化补贴进行分析，得出三点洞见。第一，太阳能获得最高的补贴率，并占减排量的三分之一以上，这反映了其与清洁设备的互补性。第二，将补贴资格限制在低收入家庭仅带来很小的成本节约。第三，如果没有环境偏好，家庭排放将高出 15% 以上。
