What Pricing Power Actually Is

When the price of a candy bar at the grocery store goes up by ten cents, almost no one notices. When the price of insulin goes up by ten dollars, diabetics notice immediately, and they buy it anyway. Both are price increases. Only one is evidence of pricing power.

Pricing power is the ability of a seller to raise prices without losing a proportionate amount of business. It is not the same as charging high prices. A boutique that charges two hundred dollars for a sweater no one buys has high prices and no pricing power. A utility that charges fifteen cents per kilowatt-hour and could charge sixteen without losing a single customer has low prices and enormous pricing power. The question is not what the number on the tag is. The question is what happens when the number changes.

Economists describe this with the concept of price elasticity of demand — the percentage change in quantity sold divided by the percentage change in price. When demand is elastic, a small price increase causes a large drop in sales, and the seller has little pricing power. When demand is inelastic, a price increase barely dents volume, and the seller has a great deal of it. Pricing power, then, is structural. It depends on whether buyers can easily walk away.

Several conditions tend to produce that inability to walk. The first is the absence of substitutes. If a drug is the only one approved for a condition, patients cannot shop around. If a software platform stores years of a company's data in a proprietary format, switching means losing the data or paying to convert it. The second is brand or identity attachment. A buyer who associates a product with a particular self-image — a Harley-Davidson motorcycle, a Hermès bag — treats alternatives as not-quite-the-same-thing, even when they are functionally equivalent. The third is small-ticket invisibility. A subscription that costs nine dollars a month falls below the threshold at which most customers bother to reevaluate it; the seller can raise it to ten without triggering a review. The fourth is regulatory or contractual lock-in. A municipal water utility, a tenant on a long lease, a hospital network with exclusive insurer contracts — none of these face buyers who can shop in the ordinary sense.

Pricing power erodes when these conditions weaken. Patents expire and generic substitutes appear. Brand loyalty fades across generations. A new entrant offers a frictionless way to migrate data. Regulators force interoperability. Each of these changes the elasticity of demand the seller faces, and the seller's ability to raise prices without losing volume shrinks accordingly. This is why firms with strong pricing power spend heavily to maintain the conditions that produce it — patents, brand investment, switching costs, exclusivity agreements — even when those investments seem disconnected from the product itself.

It is worth distinguishing pricing power from two things it resembles. It is not market power in the antitrust sense, which concerns dominance over a market as a whole; a small specialty shop can have pricing power within its niche without coming anywhere near monopoly. And it is not the same as profitability. A firm with pricing power can choose not to use it — keeping prices low to deter entrants, to build long-term loyalty, or to avoid regulatory attention. Costco famously caps the markup on its products even when customers would tolerate more. The power is the option, not the exercise.

The practical consequence for analysts is that pricing power is most reliably observed not in current prices but in past behavior under stress. When input costs rose sharply in 2021 and 2022, some firms passed the increases through to customers without losing volume; others absorbed them and watched margins compress. The first group revealed pricing power. The second revealed that whatever pricing power they thought they had was conditional on a calmer environment. Pricing power is what remains when something pulls on it.
