I don’t care who sets the price

In a landscape where economic power is often equated with the ability to dictate terms, Brian Albrecht delivers a jarring correction: the person holding the price tag is rarely the one holding the power. This piece dismantles the intuitive but flawed belief that because a firm posts a sticker price, it controls the market outcome. Albrecht brings together decades of experimental economics and historical case studies to prove that competitive forces, not administrative decisions, dictate who actually pays the bill.

The Illusion of Control

Albrecht begins by exposing a common cognitive error. "Knowing who physically announces a price tells us almost nothing about who controls that price or how the market will perform," he writes. The argument is that we confuse the mechanical act of setting a price with the economic power to control it. This distinction is vital for busy readers who might otherwise assume that corporate pricing strategies are the primary drivers of inflation or market inefficiency. The author argues that this confusion stems from what he calls the "animistic fallacy," where observers assume that because a human made a decision, that decision caused the outcome.

I don’t care who sets the price

The core of Albrecht's reasoning relies on the classic economic concept of tax incidence. He illustrates this with a simple thought experiment: if Congress shifts a tax from sellers to buyers, the economic burden does not change. "The legal obligation to write the check determines nothing about the economic incidence," he notes. What matters is the elasticity of supply and demand. This framing is effective because it uses a fundamental tenet of introductory economics to dismantle a complex-sounding critique of market theory. Critics might argue that in the real world, friction and information asymmetry prevent such perfect shifts, but Albrecht's point stands that the direction of the burden is rarely determined by who writes the check.

"Don't mistake physical appearances for Economic Forces. What matters for prediction is understanding the Economic Forces."

The Mechanics of Competition

To prove that price-setting does not equal power, Albrecht turns to the Bertrand competition model. In this scenario, two firms sell identical products and simultaneously announce prices. While both are technically "setting" prices, the equilibrium outcome forces them to price at marginal cost, earning zero profit. "Both firms are price-setters. Neither is a price-taker in the mechanical sense. Yet the equilibrium outcome is both firms pricing at marginal cost," Albrecht explains. This is a powerful counter-intuitive insight: the freedom to name a price can be a trap if a competitor is willing to undercut you by a penny.

He extends this logic to the monopolist. Even a single seller with no competitors has no control if their demand curve is perfectly flat. "The monopolist can set whatever price they want. They can announce $15 if it makes them feel powerful. But no one will buy," he writes. The physical act of posting a price is irrelevant if the market constraints are too tight. This reframing shifts the focus from the firm's internal decision-making to the external constraints imposed by consumer alternatives.

Evidence from the Lab and the Rails

Albrecht bolsters his theoretical arguments with hard data from experimental economics, specifically the work of Vernon Smith. In a 1964 study, Smith found that when sellers were the only ones allowed to post prices, the market price actually fell below the competitive equilibrium. "When sellers administer prices in Smith's experimental markets, buyers benefit," Albrecht observes. This directly contradicts the folk wisdom that sellers use price-setting to exploit buyers. Instead, the side that reveals information first is often at a disadvantage because they expose their willingness to sell, inviting competitive undercutting.

The author also cites a 1984 study by Smith, Jon Ketcham, and Arlington Williams, which showed that market institutions do matter, but not in the way critics assume. In posted-offer markets with few sellers, prices could rise due to tacit coordination, but this was a result of the specific institutional setup, not the mere act of posting prices. "The relevant institutional feature is not the superficial question of who physically announces the price," Albrecht argues. "What matters is the competitive structure: How much information do traders have? How quickly can they respond to prices?"

This theoretical framework is grounded in a historical example of the Great Northern Railway. Before 1905, the railroad held a monopoly and could set rates with impunity. When the Soo Line announced a competing track, the Great Northern's ability to control prices evaporated overnight, even though they still posted the tariffs. "Great Northern went from a monopolist that both set and controlled rates to a duopolist that set rates but had no control," Albrecht writes. The administrative mechanics remained identical, but the economic forces shifted completely.

Bottom Line

Brian Albrecht's argument is a necessary corrective to the intuition that price tags equal power, successfully demonstrating that competitive constraints, not administrative decisions, drive market outcomes. The piece's greatest strength is its synthesis of abstract theory, experimental data, and historical fact to prove that the "who" of pricing is less important than the "why" of market structure. The only vulnerability lies in the assumption that markets are always fluid enough to enforce these constraints instantly, a condition that may not hold in highly regulated or opaque industries. For the reader, the takeaway is clear: look past the sticker price and examine the competitive landscape to understand where the real power lies.

I don’t care who sets the price

by Brian Albrecht · Economic Forces · Read full article

There’s a folk wisdom out there that “setting the price”, meaning putting the sticker below the item or announcing what the price is for the good, means you have “control” over the price. Sellers post prices on shelves, so sellers must have power. That sort of thing.

This folk wisdom has intellectual backing. Many critics of mainstream economics argue that “administered pricing”—the fact that firms post prices rather than accepting them from some mythical Walrasian auctioneer—proves supply and demand theory fails to describe real markets. If firms are making deliberate pricing decisions, the argument goes, then prices aren’t being determined by impersonal market forces.

Both claims are wrong.

Knowing who physically announces a price tells us almost nothing about who controls that price or how the market will perform. The confusion stems from conflating two different things: setting a price and controlling a price. A firm sets a price when it announces what it will charge. A firm controls a price when it has meaningful discretion over what that price can be. These are not the same. A firm can set a price while having almost no control over it.

The folk wisdom commits a form of the animistic fallacy, something I’ve written about before. The assumption is that observed outcomes must result from someone’s intentional design. We see a firm posting a price and assume that decision “controlled” the outcome.

Basic economic theory says it cannot be true in general. Moreover, much empirical evidence, both experimental and observational, confirms the theory. “Setting” the price just isn’t that important in most cases.

Don’t mistake physical appearances for Economic Forces.

As a general rule, we should not mistake physical appearances for Economic Forces. What matters for prediction is understanding the Economic Forces.

The clearest way to see this is through tax incidence, a lesson from the first month of any Econ 101 course. Suppose Congress passes a law requiring sellers to send a check to the IRS for $1 per gallon of gasoline sold. The next week, they repeal that law and instead require buyers to pay $1 per gallon directly to the IRS at the pump. Does this change who actually bears the burden of the tax?

No. The legal obligation to write the check determines nothing about the economic incidence. What matters is the elasticity of supply and demand. If demand is perfectly inelastic and supply is perfectly elastic, ...
