The result of the research is that that is, in general impossible. Sure, some regulators do good work for some period. But the general forces and incentives in play push quite strongly towards the regulator being captured.
The better working alternatives are laws, where disputes or guilt are decided by courts. Since there is no regulator to capture in this scenario, things work pretty well. Of course, lawmakers can also be captured, but that's harder.
