Thanks for the reply and sorry for the delay. I can see how my second point was unclear. Let me reframe it by saying that the evidence does not support that impact investing has been, in the past, effective at providing corporations an incentive to adopt ESG. The evidence that ESG factors produced above market returns is evidence that fund flows did not raise the price of ESG factors, thus provided no incentive for corporations to adopt ESG (above whatever profit maximization incentives already existed).
On the first point, you are arguing that ESG is not priced into current prices, and that ESG factors will produce higher returns in the future. I guess I disagree. I know there are a few factors that have long track records of overperformance (value, momentum, low vol). I do not think there is sufficient evidence to claim that ESG is a similar factor. It just seams like conjecture at this point. I would say I believe in weak-form efficient market hypothesis. Basically you can get above-market returns, but it is a lot of work, and simple theories are unlikely to work.
