Green Business Cycles
This paper examines the relationship between green innovation and the business cycle, revealing that while non-green innovation is procyclical, green innovation is countercyclical. This pattern holds unconditionally over the business cycle and conditional on economic shocks. Motivated by these findings, we develop a business cycle model with endogenous green and non-green innovation to explain their distinct cyclical behavior. The key mechanism operates through a ‘green is in the future’ channel: green patents are expected to generate higher profits in the future, making green patenting less sensitive to short-term economic fluctuations. In general equilibrium, this channel is reinforced, making green and non-green innovation effective substitutes. We provide direct evidence supporting the model mechanism using data on market-implied values of green and non-green patents.
