The Green Tobin's q: theory and evidence

We derive from a dynamic stochastic model a “Green Tobin's q” as a function of a firm's green efforts (technology and pressure), as well as traditional capital stocks and investments. The evidence focuses on the oil industry which is inextricably bound to the debate on climate change. Our regression results indicate a negative impact on Tobin's q from green technologies, and a positive impact on Tobin's q from green stockholder pressure. In addition to adding a theoretical model, we provide empirical evidence regarding pressing issues in the energy transition.
