“There is a fundamental problem with regulators. If a regulator agrees to change a rule and something bad happens, they could easily lose their career. Whereas if they change a rule and something good happens, they don’t even get a reward. So, it’s very asymmetric. It’s then very easy to understand why regulators resist changing the rules. It’s because there’s a big punishment on one side and no reward on the other. How would any rational person behave in such a scenario?”
