How Prices Work

It’s easy to blame greedy drug companies, hospitals, or insurers for high health care bills. But they wanted to earn money in 2000, too, and so do drug companies and hospitals in other countries, where prices are far lower. To explain high prices, look for what’s different and what changed. Start with how economists describe a market economy.

In health care, prices often can’t do their job. Insurers, employers, and government pay most bills, so patients rarely see or compare prices. Patients also know less than their doctors, and when you’re sick or hurt you can’t easily shop around. When buyers can’t see prices and sellers don’t compete on them, prices send weaker signals.

Work through five questions whenever a price changes:

The Price Detective Checklist
The Price Detective ChecklistWhat to look forIn the health care market
1. Supply and demand. What shifted, and how strongly do buyers and sellers respond?Shifts in supply or demand; price elasticities of demand and supplyAn aging population, new treatments, and patients who see little of the price
2. Government. Did a price control, tax, subsidy, quota, or tariff change?Policies that push demand up or hold supply backTax break for job-based insurance, Medicare and Medicaid, licensing and facility rules
3. Market power. How competitive is the market?Number of sellers, barriers to entry, and how many alternatives buyers haveHospital mergers, drug patents, and a few large drug middlemen
4. Price discrimination. Do different buyers pay different prices for the same thing?Price differences by customer that costs don’t explainPrivate insurers pay far more than Medicare for the same hospital stay
5. Inflation. Is it one price, or nearly all prices?Monetary policy of the Federal Reserve and fiscal policy of the federal governmentHospital prices rose about twice as fast as prices overall

Start Here: What Changed?

Not every health care price rose fast. Hospital prices far outpaced overall inflation, while doctors’ prices rose more slowly than prices overall:

What Changed?: Consumer price index
Consumer price indexSept. 2000Sept. 2026Change
Hospital services100393nearly quadrupled
All consumer prices100194nearly doubled
Prescription drugs100189nearly doubled
Physicians’ services100178up 78%

Each index is set to 100 in September 2000. The drug index tracks list prices, not rebates.

Americans spend much more on health care than people in other rich countries, and they pay little of it directly:

What Changed?: Health spending
Health spendingAmount
U.S. total, 2024$5.3 trillion (18% of GDP)
U.S. per person, 2024 (peer-comparison basis)$14,775
Average of comparable rich countries, per person$7,860
Share paid out of pocket by patients11%
Average family job-based premium, 2025 (worker pays)$26,993 ($6,850)

What changed, and what didn’t? A major study comparing the U.S. with 10 rich countries found Americans use about as much care, such as doctor visits and hospital stays. The difference is mainly prices: for labor, drugs, and devices, plus higher administrative costs. So the question is why U.S. prices are so high.

Running the Checklist on Health Care

1 Supply and demand: more demand, slow-growing supply

  • Demand rose. An aging population needs more care: Medicare covered 66.6 million people in 2024. New treatments also add value people want to buy, from cancer drugs to joint replacements.
  • Patients see little of the price. When insurance pays most of the bill, patients use more care than they would if they paid the full price. One study found the spread of insurance explains at least 40% of the rise in real health spending per person from 1950 to 1990.
  • Supply responds slowly. It takes more than a decade to train a doctor, and caring for patients is hard to automate. A medical school association projects a shortage of 13,500 to 86,000 physicians by 2036.

READ How Do People Respond to Prices?, section ①. When insurance pays most of the bill, the price a patient sees is low, but the full price also includes time.

2 Government: policies that push demand up and hold supply back

Government is a huge buyer of care, with Medicare alone paying about 21% of all health spending, and it writes many of the rules. Many of these policies help people get care. But when demand rises and supply is held back, prices rise.

Running the Checklist on Health Care: Pushes demand up
Pushes demand upHow it raises pricesWhat the evidence shows
Tax break for job-based insuranceInsurance from an employer isn’t taxed as income, so workers get more generous plans in place of wages.The tax break will cost about $290 billion in income taxes in 2026. The Congressional Budget Office says it encourages plans with lower out-of-pocket costs, raising total spending.
Medicare and MedicaidCovering more people means more care purchased, much of it by people who otherwise couldn’t afford it.After Medicare began in 1966, hospital spending rose sharply, a major piece of the 40% insurance effect.
Running the Checklist on Health Care: Holds supply back
Holds supply backHow it raises pricesWhat the evidence shows
Certificate of need lawsHospitals and clinics must get state approval to open or expand, and rivals can object.Federal antitrust agencies told South Carolina these laws “create barriers to expansion, limit consumer choice, and stifle innovation.” SC’s hospital rule ends in 2027.
Limits on doctor trainingSince 1997, Medicare has capped the residency slots it funds near 1996 levels.Fewer new doctors than demand calls for; projected shortages through 2036.
Scope-of-practice rulesStates limit what nurse practitioners can do without a doctor.The Federal Trade Commission found these limits reduce the supply of primary care.
Drug approval costsTesting new drugs is long and expensive, and few succeed.About 12% of drugs entering trials are approved; costs run from under $1 billion to over $2 billion per new drug.

3 Market power: fewer rivals, higher prices

  • Hospitals. Hospitals with no nearby rivals charge about 12% more than those in markets with four or more.
  • Drug patents. Patents give new drugs years without competition. That reward pays for research, but it means high prices until generics arrive. Generics, about 90% of U.S. prescriptions, are cheaper here than in most other rich countries.
  • Middlemen. Three companies manage most prescription drug benefits. The Federal Trade Commission found they marked up some specialty generic drugs by $7.3 billion over their cost from 2017 to 2022.

4 Price discrimination: who pays matters

The same hospital stay has very different prices depending on who pays. In 2022, private insurers paid hospitals about 254% of what Medicare paid for the same services. Brand-name drugs cost at least three times as much in the U.S. as in other rich countries, even after rebates. Higher expected revenue also gives drug makers more reason to invest in research, and most new drugs launch in the U.S. first.

5 Inflation: why hospital prices rise faster

Hospital prices nearly quadrupled from 2000 to 2026, while prices overall nearly doubled. That isn’t general inflation; it’s a change in hospital prices compared with other prices. Hospitals run on skilled labor that is hard to replace with machines, and with fewer rivals, they can pass those costs on.

What Can Government Do?

What Can Government Do?: Tool
ToolHow it worksThe catchWhat the evidence shows
Repeal certificate of need lawsLets hospitals and clinics open or expand without state approval.New facilities may serve profitable patients, leaving rural hospitals less revenue.12 states have repealed; SC is phasing its law out
Train more providersFunds more residency slots; lets nurse practitioners do more.Costs taxpayers, and training takes years.FTC finds limits reduce primary care supply
Limit the tax breakCaps how much job-based insurance escapes taxes.Raises taxes on many workers.CBO says total spending would fall
Negotiate drug pricesMedicare negotiates prices for some high-cost drugs.Lower prices may mean slightly fewer new drugs.22% lower net spending on 10 drugs in 2026
Enforce antitrustBlocks hospital mergers; reviews drug middlemen.Slow and costly; some mergers may improve care.Monopoly hospitals charge about 12% more

Fair Challenges

Decide what you think of each challenge first, then open the response.

“Greedy drug companies are the problem.”
Brand-name drugs cost much more here, and patents limit competition. But drug companies wanted profits in other countries too, where prices are lower; the difference is how prices are set. Drugs are also a small part of spending: hospitals and doctors cost far more. And high prices fund research: lowering them could mean fewer new drugs, though estimates of how many vary.
“Insurers are the problem.”
Insurance paperwork adds to administrative costs. But insurers in concentrated markets often push hospital prices down, not up. The deeper issue is that third-party payment weakens price shopping, whoever the payer is.
“Just adopt single payer.”
The Congressional Budget Office found it could cover nearly everyone and lower out-of-pocket and administrative costs, but would raise federal spending sharply. Demand for care would grow faster than supply, leading to more delays, especially for specialty care. Whether that trade-off is worth it is a value question.
“Nonprofit hospitals don’t care about profit.”
About 58% of community hospitals are nonprofits, and their tax breaks were worth about $28 billion in 2020. But nonprofits also merge, raise prices where they lack rivals, and spend surpluses on expansion. Ownership matters less than competition.
“Just make prices public.”
Hospitals must now post prices, and the No Surprises Act bans many surprise bills. That helps. But only about a third of spending is on care you can plan and shop for; you can’t compare prices in an ambulance.
“Health care isn’t a normal market.”
Partly true: Arrow showed uncertainty and unequal information make it different. But incentives still work. Patients still respond to prices when they see them, and providers still respond to rules that limit entry. That is why the checklist still helps.

The Normative Question

Economics can show how insurance, taxes, licensing, and competition affect prices, spending, and access to care. It can’t decide whether health care is mainly a right or a service people buy, how much to trade lower prices for faster access to new treatments, or who should pay. Every choice, including keeping today’s system, puts the cost on someone.
