中文摘要
我们研究个体发明者如何响应从事“清洁”电力技术工作的激励。利用天然气价格变动，我们估计了发明者的产出弹性和进入弹性，并衡量了一次价格上升（对应于碳的社会成本）的中期影响。我们发现，由此诱发的清洁创新反应主要来自现有的清洁发明者；新发明者在边际上的反应，不及其在清洁能源专利方面的平均贡献所显示的那样大。我们的结果强化了政府干预以加快能源转型的理由。（JEL L94, O31, O34, Q35, Q42, Q55）
Abstract
We study how individual inventors respond to incentives to work on “clean” electricity technologies. Using natural gas price variation, we estimate output and entry elasticities of inventors and measure the medium-term impacts of a price increase mirroring the social cost of carbon. We find that the induced clean innovation response primarily comes from existing clean inventors. New inventors are less responsive on the margin than their average contribution to clean energy patenting would indicate. Our results strengthen the rationale for government intervention to expedite the energy transition. (JEL L94, O31, O34, Q35, Q42, Q55)
