促进可再生能源政策的主要目标是纠正燃烧化石燃料带来的无法定价的污染外部性。然而，很难评估这些政策是否以及在多大程度上促进了工业增长和经济福利，特别是在没有适当对照组的可比数据的情况下。本文提供了一个实证框架来解决这一问题，并特别关注日本使用消费者补贴安装住宅太阳能光伏系统。所提出的估计显示了弹性需求、小规模的实践学习以及生产中的适度学习溢出效应。我们的模拟表明，虽然补贴是鼓励更多使用太阳能电池板的有效工具，但除非减少二氧化碳排放的价值远高于当前的市场价格，否则它们将加剧社会盈余。
The primary goal of policies to promote renewable energy is to correct for the unpriced pollution externalities from burning fossil fuels. It is, however, difficult to assess whether and to what extent these policies enhance industry growth and economic welfare, especially when no comparable data on a proper control group are available. This paper provides an empirical framework to tackle such a problem with a particular focus on the use of consumer subsidies for installing residential solar photovoltaic systems in Japan. The presented estimates show elastic demand, and small learning by doing along with modest learning spillovers in production. Our simulations show that, while the subsidies are an effective instrument to encourage the greater use of solar panels, they would exacerbate social surplus unless the value of mitigating CO2 emission is well above the ongoing market price.
