Regulatory Capture
What is Regulatory Capture?
Regulatory capture is when a regulator ends up serving the industry it oversees rather than the public, because the industry lobbies and the public does not.
Capture follows from an asymmetry of incentives. A rule that raises industry profit by a large amount per firm costs each consumer a few dollars, so the firms hire lawyers, submit evidence and attend every hearing while consumers do nothing, which is the concentrated benefits and diffuse costs problem. The agency also depends on the industry for the technical information it needs, and staff often move between the agency and the firms it supervises, so the industry's framing becomes the agency's framing. The results look like restricted entry, protected prices and standards written around what incumbents already do. Capture is not the same as bribery: it usually operates through entirely legal channels and can happen with honest officials, which is why economists file it under government failure rather than crime.
Regulatory Capture: a worked example
Occupational licensing is where students meet capture most often. Suppose a state cosmetology board, most of whose members are working salon owners, sets the required training at 1,500 hours. At a school charging $10 an hour that is $15,000 in tuition, plus roughly nine months of forgone wages, so fewer people qualify and existing salons face less new competition. The board can point to hygiene and safety as the reason, and some of that is genuine, which is exactly what makes capture hard to identify: the public-interest justification and the incumbent's interest point the same way.
The mistake students make with regulatory capture
Students assume that once a market failure is identified, regulation fixes it, so the only question left is whether to regulate. Capture is the reason that does not follow. An agency staffed by honest people can still write rules that favor incumbents, because the industry supplies the information and the political pressure while consumers supply neither. Comparing a real market against an ideal regulator, rather than a real one, overstates the case for intervening.
Regulatory Capture questions
What causes regulatory capture?
Regulatory capture is caused by an imbalance in who bothers to participate: each regulated firm has a great deal riding on the rules while each consumer has very little, so only one side lobbies consistently. Dependence on industry data and the movement of staff between the agency and the firms reinforce it.
What is an example of regulatory capture?
The standard textbook example is the Interstate Commerce Commission, the agency created to regulate American railroad rates, which economists argued came to protect the carriers it oversaw by limiting entry and holding rates up, and which was eventually wound down as transport was deregulated. Licensing boards staffed by members of the licensed profession are the everyday version.
How can regulatory capture be reduced?
Capture is reduced by making the regulator less dependent on the industry it oversees. That means independent funding and in-house technical expertise, published records of meetings and lobbying, waiting periods before staff can take industry jobs, and consumer representatives with standing to challenge decisions. Periodic reviews that force old rules to be justified again also help, since capture tends to show up in rules nobody revisits.
