“…We expand the work of Ortiz‐de‐Mandojana and Aragon‐Correa (2015) by using a large panel sample that includes firms both in more and less environmentally impacting industries and test for the industry effects. By investigating a developed country, we also expand on the findings of Zou, Xie, Qi, and Yang (2019), Zou, Xie, Meng, and Yang (2019), and Sun, Li, Geng, Yang, and Zhang (2020), who investigate emerging economies.
