Tom Gosling talks to Dimitri Vayanos about the impact the green investors can have on stock prices by divesting from dirty firms and investing in green firms. There's a debate in the academic literature about whether the impacts are negligible or substantial. Using a theoretical model, Dimitri and his co-authors identify a significant but modest impact on cost of capital, measured in a few tens of basis points and share price impacts over a decade of around 10%. So noticeable, but not transformative in the context of the green transition.
