Never Assume Regulation Kills Efficiency if You Want a Market That Actually Works

Never walk into a policy debate assuming regulation is a cuss word. I get why people do it. The term conjures images of stacked paperwork, permitting delays, and some mid-level official demanding a third environmental assessment for a storage shed. That version of regulation deserves its bad reputation.

But here’s the uncomfortable truth: every market that has ever functioned at scale has been built on a foundation of rules. Every single one. The question was never whether to regulate. It was always how, and how much, and in whose interest.

That framing tends to annoy everyone equally. Free-market true believers hear it as a surrender to statism. Left-leaning skeptics hear it as a cop-out that legitimizes corporate capture. Fine. Let’s unpack both reactions, because the real story about government regulation and its effect on economic efficiency is far less dramatic than either camp wants it to be.

So before you reach for the nearest guillotine for the administrative state—or, equally, before you smother a startup in compliance forms—hear me out.

The False Dichotomy That Keeps Everyone Stupid

Here’s the standard mental model: you draw a line, put “heavy regulation” on one end and “free markets” on the other, and assume the efficient optimum sits somewhere near the right. It’s tidy. It appeals to common sense. It also collapses the moment you look at how actual markets work.

A so-called free market doesn’t spontaneously generate its own ground rules. Strangers don’t exchange money for goods or services without some shared expectation that contracts mean something. When you buy a used car, you’re relying on title laws. When you sign a mortgage, you’re relying on recording statutes and foreclosure procedures and the fact that a court will enforce the terms. When you invest in a public company, you’re relying on disclosure rules that make the financial statements less than a work of complete fiction.

That’s all regulation. It’s in the water supply of every advanced economy.

Economists like to talk about the “institutional underpinnings of markets,” which is a polite way of saying: somebody has to write the rules, update them, and hold people to them. The OECD’s body of work on regulatory policy makes precisely this point year after year. Jurisdictions with clearer, more predictable, better-enforced rules tend to attract more investment and generate more productive activity, not less, relative to chaotic free-for-alls. The correlation isn’t perfect. But it’s persistent.

So the binary framing is wrong. Regulation isn’t a dial that you simply crank down to unleash economic vitality. It’s a design problem. And design is where the conversation usually breaks down.

Define the Enemy Properly

Let me be precise about what efficiency means, because the word gets thrown around like a beach ball at a stadium concert.

When economists say “efficient,” they usually mean one of three things:

• Allocative efficiency: resources flowing toward their highest-value uses.
• Productive efficiency: goods and services produced at the lowest possible cost.
• Dynamic efficiency: innovation and adaptation over time.

A regulation can hurt all three. It can also help all three. The difference usually comes down to whether the rule corrects a genuine market failure or just redistributes rents toward politically connected incumbents.

Here’s the kicker: many of the rules that generate the loudest complaints—mandatory disclosure, capital adequacy requirements, workplace safety standards—are precisely the ones that reduce the information gaps and transaction costs that make markets sluggish in the first place.

When banks are forced to disclose their risk exposures, investors can price debt more intelligently. Capital flows to sounder projects instead of vanishing into leverage black holes. That’s allocative efficiency improving because of a mandate. Not in spite of it.

When public companies have to file standardized financial statements, due diligence becomes cheaper and faster. That lowers transaction costs across the entire equity market.

Are these burdens? Sure, in isolation. Compiling and auditing financial statements is real work, and it costs real money. But compare those compliance costs to the alternative: every investor running private forensics on every potential counterparty, because nobody trusts the public numbers. That’s a world where capital markets basically don’t exist, or exist only for a narrow circle of insiders with the resources to hire their own analysts.

Good regulation is expensive. The absence of good regulation is often more expensive.

When Regulation Genuinely Is Deadweight

Now, I’m not going to pretend every regulation earns its keep. That would be a different kind of fairy tale.

A hedge fund friend of mine likes to joke that regulation is just a tax on being the only honest guy in the room. I tell him that’s also what burglars think about locks. But he has a point, buried under the cynicism.

Some licensing regimes are pure rent-protection. Occupational licensing for hair braiding, interior design, or florist work often does little to protect public health and a lot to keep competition out. The empirical literature on the regulation of entry, going back to the influential work of Djankov, La Porta, Lopez-de-Silanes and Shleifer, found that heavier entry regulation is associated with more corruption and larger unofficial economies, not better quality goods and services. Those studies help explain the grain of truth in every “red tape is suffocating business” complaint.

So I’m not here to defend every rule that has ever been written. Rules can be outdated, contradictory, captured by incumbent interests, or just plain stupid. The point is narrower and more stubborn: that is an argument for better regulation, not for less of it.

Consider the difference between a building code that requires licensed electricians to handle major wiring and a rule that requires a license to give someone a haircut. The first genuinely prevents fires. The second just prevents hairdressers from competing with salons that already have political clout.

One is underpinned by a legitimate market failure—information asymmetry between a consumer and someone doing dangerous work—and the other is a story about who gets to slice people’s split ends for money.

Conflating the two is how we end up with ideologies instead of policy.

Where Regulation Sharpens, Rather Than Dulls, the Market

Let me make the affirmative case in a more structured way. There are four recurring situations where careful government regulation doesn’t impede efficiency. It’s what makes efficiency possible in the first place.

A quick, non-exhaustive list:

• Externalities: pollution, pandemics, and climate change. Prices don’t capture the full social cost of a ton of carbon. Rules, whether carbon pricing or emission standards, force those costs back into the decision-making calculus of firms and households.
• Information asymmetries: food labels, securities disclosure, drug efficacy testing. The seller almost always knows more than the buyer, and, when the gap gets too wide, the market contracts to a market for lemons—low-quality goods driving out everything else.
• Natural monopolies: electricity grids, water systems, certain rail infrastructure. Duplicating that infrastructure would be absurdly wasteful, so we hand a monopoly to one operator and use rate regulation to stop it from charging monopoly prices.
• Coordination and interoperability: radio spectrum allocation, technical standards for wireless charging, safety protocols for rail networks. Everyone benefits when everyone uses the same rules of the road.

There are good case studies hiding in plain sight on almost all of these. Wait, actually, we should not quietly skate past the environmental example, because the numbers there are so lopsided.

The Underrated Environmental Record

In the United States, the Clean Air Act has been one of the most heavily criticized pieces of economic regulation in modern history. Industry groups predicted disaster at every amendment. And yet, by the EPA’s own benefit-cost analyses, the cumulative benefits of Clean Air Act programs between 1990 and 2020 dwarf their costs by margins that are almost embarrassing to quote. Look at the agency’s own review of the Clean Air Act and the economy and the ratio is enormous, something on the order of thirty to one by most credible tallies.

That’s not to say the EPA is always right, universally efficient, or incapable of going overboard. It’s to say the reflexive narrative that regulation is a deadweight on the economy is simply not consistent with the evidence in one of the most heavily regulated domains in the developed world.

In fact, the more honest economic story is the reverse: the deadweight comes from uncertainty about regulation. Firms can adapt to almost any stable set of rules. What they cannot adapt to is a regulatory environment that flips direction every election cycle, that stacks inconsistent requirements across different agencies, or that leaves large questions about enforcement in permanent limbo.

Predictability, not laxity, is the real friend of investment.

A Crisis Is a Terrible Thing to Waste, and Oversight Prevents Crises

Want to talk about economic efficiency collateral damage? The 2008 financial crisis is the bulletin board case. In the years before the crash, financial engineering ran so far ahead of oversight that nobody—not the banks, not the rating agencies, not the regulators—had a clear line of sight on the systemic risk embedded in mortgage-backed securities.

The resulting economic contraction was the most efficient-economy-destroying event since the Great Depression. Trillions in wealth evaporated. Unemployment soared. A decade of productivity growth essentially vanished into a hole of balance-sheet repair.

Now, I’m not naive enough to claim that smarter regulation would have prevented every bad loan or every act of seller fraud. Markets will always contain a residue of human error and human greed. But the absence of basic regulatory plumbing in the shadow banking system didn’t create freedom. It created opacity. And opacity is to financial markets what fog is to an airport: it’s not a market condition, it’s a reason to shut down all flights.

Here’s the part the deregulatory crowd rarely concedes: the credibility of economic systems depends on someone standing outside the game and enforcing the rules. A market that is believed to be rigged, opaque, or underpinned by implicit bailouts develops fewer arm’s-length transactions, wider bid-ask spreads, and higher costs of capital for everyone. Regulation that restores trust doesn’t tax the market. It oils the motor.

The Principles of Regulation That Actually Respects Efficiency

If we can agree that rules are occasionally useful in principle, the practical question becomes: how do you tell good ones from bad ones in advance?

I’ve pulled enough regulatory weeds over the years to offer a few ground rules. You might disagree with the details, but I’d defend the broad direction of all of them.

1. Name the market failure before you write anything

If you can’t articulate what specific market failure you are correcting—information asymmetry, externality, monopoly, coordination problem—then you’re likely writing regulation to protect an incumbent, soothe a political constituency, or make someone’s résumé look impactful.

Do the analysis first. If there’s no failure, there’s no regulatory mandate. This sounds like commonsense, but a startling portion of the administrative state skips straight from political impulse to rule-writing.

2. Do the cost-benefit analysis, and do it honestly

Formal cost-benefit analysis has been a legal requirement for major federal regulations in the U.S. since the Reagan administration, and it’s a genuinely good discipline when it’s applied without a pre-ordained conclusion.

The problem isn’t the tool. The problem is when agencies get pressure to inflate benefits or ignore costs to justify a predetermined political outcome, or when the other side does the reverse in opposition. A tool is not the same as a conclusion. Use the tool properly—put real numbers on both sides, account for alternatives, acknowledge uncertainty—and you usually get a defensible rule.

Don’t look at cost-benefit analysis as a gut-check ritual. Look at it as the central organizing principle of regulatory humility.

3. Prefer performance standards to design standards

This is one of the underrated levers in regulatory design. Where possible, tell firms what outcome you want—fewer workplace injuries, lower particulate emissions, safer food—and let them figure out how to get there.

Design standards, which dictate specific technologies or processes (“you must install this exact filter model”), tend to freeze the state of the art. They reward clever regulators rather than clever engineers. A performance standard keeps the pressure on innovation, because the cheapest way to hit the target can change as technology improves.

4. Write rules that expire

Yes, really. Sunset clauses are unpopular with regulators and with the industries that have grown comfortable with existing rules, but they serve a real function: forcing periodic review of whether a rule actually does what it claimed to do and at what cost.

Some of the most inefficient regulations in existence are old ones. Not old and wrong, just old and irrelevant, quietly collecting compliance costs long after the problem they solved has changed shape. Mandatory periodic review, not permanent rule, would flush some of that waste out of the system.
