Thanks and Some Additional Comments

I wanted to thank Frank Pasquale for organizing and hosting this symposium and all of the participants for the time they took reading The Economic Dynamics of Law and providing their thoughts. I wanted to say a little about the most recent posts, even though it’s possible that something more might appear before the weekend is out.

I’m happy to accept Livermore’s suggestion that systemic risk avoidance and keeping open a robust set of economic opportunities can be thought of as an incompletely theorized agreement about goals. He may be right that in fact avoiding systemic risk is efficient, but I doubt that all climate disruption cost-benefit analysis (CBA) would necessarily reveal that. Showing that most current CBA would call for some action on climate disruption does not suffice to show the congruence between CBA and avoidance of systemic risk taking into account collateral negative consequences (which is narrower than taking into account all costs under my normative framework). First, there is a historical problem. Prominent early CBA and much of the CBA from a few years ago would not invite vigorous measures to address climate disruption (although some CBA did early on). Even today, there may be a discrepancy between what scientists tell us we need to minimize significant risk, a phase-out of fossil fuels, and what some of the CBA is telling us. CBA is basically guesswork, and does not yield a reasonably specific answer when substantial uncertainties exist. Read More
