price controls, supply and demand, zero-pricing policy

“Why can’t everything be free?” I’m always delighted whenever a child asks me, because I have an intellectually solid answer even a child can understand. Namely: If everyone had to produce for free, there would be virtually nothing to buy. If everything had a price of zero, consumers would strive to fill their shopping carts with anything they could get their hands on. Producers, however, would basically stop working.

(To be clear, this assumes that government strictly enforces this disastrous law. In the real world, even terrified North Koreans break the law when starvation is their only alternative).

What few children would understand is the following diagram. In a perfect world, I would have just copied it out of the textbook. But as far as I know, no textbooks actually contain this diagram, so I made it myself.

Why Can't Everything Be Free? - Econlib (3)

In a normal supply-and-demand diagram, the shaded area shows total gains from trade. With a price control of zero, however, the shaded area becomes the deadweight cost. How can deadweight costs equal gains from trade? Because a price control of zero annihilates the entire market, driving production down to zero. The unintended consequence of a price control of zero is a market quantity of zero.

Is any government demented enough to impose such draconian price controls? Yes; virtually all governments do so. Most notably, while organ donation is normally legal, organ markets are almost always banned. In other words, organs are something you can give away for free but may not sell at any price. Which is equivalent to a price ceiling of zero.

Still, price controls this draconian are extremely rare. What is not rare, however, is a seemingly slight variation on zero-pricing. When children ask, “Why can’t everything be free?,” they might be visualizing a world where charging money for goods is illegal. Most of the time, however, they are probably visualizing something quite different: A world where government directly gives everyone what they want, free of charge. Gratis.

What’s wrong with that? The easy answer is to say, “Well,someone has to pay for stuff, so government freebies ultimately mean enormous taxes.” That’s true, but misses the deeper economic insight. Namely: Giving people whatever they want, free of charge, is extremely wasteful, because it leads people to consume products they barely appreciate. I’ve said it before and I’ll say it again: Gratis is not great.

To see what I have in mind, ponder the following diagram:

Why Can't Everything Be Free? - Econlib (4)

What’s going on? On the generous assumption that government keeps per-unit costs at their original level, the efficient outcome is for consumers to go to the intersection of supply and demand. This maximizes the excess of benefits over costs. But if goods are free, consumers don’t stop there. Instead, they consume and consume and consume until they hit the dashed vertical line, which shows total quantity when demand intersects the x-axis. All units to the right of the intersection of supply-and-demand cost more to produce than the benefit they yield. Summing all these losses gives us the shaded area – which could in principle (though not as drawn) exceed the total surplus generated by the good’s existence.

Upshot: It is entirely possible that giving goods away for free without limitation is even less efficient than the good not existing at all!

Does this really happen in the real world? Verily. Any country that lets people have unlimited health care or education for free qualifies. To avoid this massive waste, you need death panels and such.

Is gratis pricing always bad? Not quite. For thoroughly non-rivalrous goods, gratis pricing is maximally efficient, at least in the short-run. (Though the long-run can be a totally different story). Similarly, gratis pricing is maximally efficient ifother prices have already done their job. In a free market, landlords charge people for their location, so there is no need for an additional “immigration charge” on top. And of course, when transactions costs are high relative to the value of the goods, gratis pricing can be the least-inefficient option. Charging people for soap at a hotel makes little sense, because almost everyone wants a little soap, hardly anyone wants a lot of soap, soap is cheap, and collecting soap fees is expensive.

What about positive externalities? Gratis pricing can be efficient if positive externalities are massive. In all other cases, however, free is overkill. Usually severe overkill.

The pathologies of zero-pricing are one of the most important topics that every econ textbook I know of totally neglects. And I can’t help but think that the reason is Social Desirability Bias. Human beings love the image of giving everyone what they need, free of charge. Demagogues capitalize on this love. That’s probably why education and health spending are so bloated; giving everyone all they want is folly, but this folly sounds ever so sweet. To discover that “Gratis is not great!” is crucial for economic literacy. But so enlightening your students is as thankless as telling them that Santa Claus doesn’t exist.

But collecting tolls used to be very costly. (It is less so nowadays.)

Why was it costly?

I can see that trying to charge people for each individual trip was inconvenient.

But even with primitive technology you can sell them a sticker they can put on their car that allows to drive during a specific time. (Eg specific days or specific times of day.)

Just fine everyone who doesn’t display the right sticker.

“Free” healthcare seems a bit more complicated than that. Personally I would not use any more healthcare if it was free. Everyone I know would rather not see a doctor or take any more medicine if they didn’t have to. I’m sure there are some people who overuse healthcare but it’s not clear to me how much more they would do it if it was free, and if such a cost is greater than the massive waste of the current US system.

Despite having very good healthcare benefits from my employers I’ve had to spend an inordinate amount of time managing it. When my twins were born they spent several weeks int the NICU. While I’m happy with the outcome, my partner and I spent literally hours a day for months dealing with the resulting paperwork. We could dispute out-of-network rates for nurses because we had no choice in who the hospital assigned, but we had to do it individually for every bill, for every shift, for every nurse. The hospital also assigned a specific person to work with us, who again must have spent hours per day helpful us. So in addition to paying for the insurance, and maxing out our out-of-pocket expenses, we also had to spend most of our “free time” on healthcare overhead while also working full time and handling two infants. My partner and I are well educated with extensive math and business experience. I can’t imagine how most people without those skills deal with stuff like this.

Is it unreasonable that I am jealous of every other developed country in the world where I could have avoided all that headache? And while this is just the most egregious example, there’s not a month that goes buy that I have to dispute or reconcile some insurance claim.

I have to believe there’s a more efficient way to handle healthcare in this country. Getting worse value while spending more than other countries seems like a poor outcome for having more of a free market solution.

It seems debatable that the US has a more free market healthcare system than most developed countries. The paperwork is largely due to the unnecessary extent to which healthcare provision is mediated through insurance, itself an artifact of state subsidization or mandate.
Other countries save money mainly through more stringent rationing, which doesn’t have adverse outcome effects because so much of healthcare is waste anyway. It seems doubtful that the same American electorate that insists on such extensive subsidies for nominally privately provided healthcare is going to tolerate strict rationing under healthcare socialism. Looking at much more Medicare spends per patient compared to what other countries pay per patient in the same group doesn’t seem consistent with the thesis that the main reason healthcare is more expensive here is because it isn’t as socialized.

Josh S
Feb 9 2022 at 8:55pm

Agreed on your point about how free market US healthcare is.
I don’t have a choice in the subsidies (which I’ve never advocated for) and I don’t have any choice in which insurance provider my employer has either.

Have a look at Singapore for excellent and cheap healthcare. Cheap as measured by total proportion of GDP spent. Excellent as measured by health outcomes.

If you want a US example, look at what the Amish are doing. Skatestarcodex has a write up.

“Free” healthcare seems a bit more complicated than that. Personally I would not use any more healthcare if it was free. Everyone I know would rather not see a doctor or take any more medicine if they didn’t have to. I’m sure there are some people who overuse healthcare but it’s not clear to me how much more they would do it if it was free, and if such a cost is greater than the massive waste of the current US system.

Certainly many people wouldn’t value additional healthcare even if it was free. Medicine has diminishing returns — going to the doctor offers very little benefit if you feel well. But some people would consume more if it were free and in the narrow economic sense it’s wasteful to give it to them. I think that this point is obscured in the US because people don’t realize that a great proportion of health care services are already free at the margin, so wasteful excess is already maximally achieved. Consider:

Most health care spending is by people who are insured
Many insured people face very small marginal costs for additional health services
Most health care spending is by people with expensive chronic conditions (e.g. cancer, heart disease, diabetes, autoimmune conditions). Even among those with deductibles or large coinsurance obligations, a typical expenditure is by someone who has already spent a lot of money on health care this year and thus probably already reached their out of pocket maximum, making marginal costs near zero
Truly uninsured people with expensive chronic conditions are rare enough that their providers can often secure free or deeply discounted treatments for them

I work in medical oncology, where increasingly our drugs are extremely expensive, often several hundred thousand dollars per year. The majority of patients will have the same financial obligation whether we prescribe a therapy that’s $2000/year or one that’s $200,000/year. If we can show them that the latter treatment is, say 5% more effective, or has 20% fewer side effects, nearly everyone will go for it. This almost certainly wasteful in the way that Bryan describes.

In my own experience, I have few health problems apart from a minor autoimmune condition which is annoying but has little effect on my life. There are some cheap treatments for this that I use and which are modestly effective, and also some that are more effective but cost somewhere between $10,000 and $100,000/year. I’d be willing to pay probably around $1000/year to have my condition go away, so I am not interested in these treatments. If they were free, I would definitely take them, and this would be quite wasteful.

To avoid this massive waste, you need death panels and such.

I’m all for death panels but we’re failing at getting death panels we want say that would cut medicare spending in half, so how about alternatively for to give medicare recipients better incentives how about we try at age 65 the Government funds a health saving account with $30k, then at 70 years old they get to keep what is left if anything in the account, but if they go over Medicare will pay for all of the overage, then again at 70 fund their health saving account with another $30k for and then at 75 years old they get to keep what is left. Etc. until death.

David Goldhill claimed, one out of five 90 year olds will have surgery on the year of their death, when no surgery is recommended for someone over 90 years old. If their estates could keep the money they might not get the surgery.
It could also give people an incentive to seek treatment outside the USA where it is cheaper and or maybe go with Direct Primary Care.

Love the graphs.“I have an intellectually solid answer even a child can understand. Namely: If everyone had to produce for free, there would be virtually nothing to buy.” My kid asked me that question when she was six. I told her I would give her two dollars a week to clean her room. The incentive worked. I then asked, would she do it for nothing? She said no because I offered two bucks. With no payment to clean her room, she said she would rather play a video game. A six year old kid understood the economic principles of scarcity, trade-offs, opportunity cost, incentives and TANSTAFIL.

Human beings love the image of giving everyone what they need, free of charge. Demagogues capitalize on this love. That’s probably why education and health spending are so bloated; giving everyone all they want is folly, but this folly sounds ever so sweet. To discover that “Gratis is not great!” is crucial for economic literacy.

Amen. “Free” can be quite expensive – including for the recipient! Socialized healthcare systems are a classic example of that (a very good primer on their problems is Thomas Sowell’s chapter on medical care in Applied Economics). There’s been quite a few examples of waste due to subsidies (“gratis” or free pricing is the equivalent of a 100% subsidy), including in medical care.

“After Canada’s Quebec province created its own government health plan back in the 1970s, telephone consultations went down, office visits went up and the time per visit went down. In other words, medical conditions which neither the doctor nor the patient previously thought serious enough to require an office visit, before price controls, now took up more time by both the patient (in travel time) and the doctor (in the office), thereby reducing the time available to people who had more serious conditions.” Sowell, Thomas. Applied Economics (pp. 55-56). Basic Books. Kindle Edition. I’m not aware of any medical revolution that discovered it was “necessary” for people to go to the office more, rather than continuing with telephone consultations. But I am aware of a price “revolution” (the politically lowered prices) that would cause such behavior!

‘Excessive prescriptions were reported as “routine” under China’s government-provided medical care and patients there “leave the dispensary with bags, rather than bottles, full of pills.’ China has subsequently moved away from government-provided medical care.” Sowell, Thomas. Applied Economics (pp. 59-60). Basic Books. Kindle Edition. Price ceilings caused more usage/hoarding of pills than would otherwise occur!

“Economists have observed the effects of insurance policy changes on the demand for health care. One experiment asked a group of California Medicaid beneficiaries to pay $1 for their first two office visits each month, while a similar group continued to receive completely free service. This modest charge reduced office visits by 8 percent.4 Other studies have found that even small changes in time cost can have an effect. For example, when the health facility at one college was moved so that it took 20 minutes rather than five to ten to walk there, student visits fell by nearly 40 percent.5 Whether the health services forgone in these cases were necessary remains an open question, but surely the behavior of the potential patients was not dominated by their health needs.” Rhoads, Steven E.. The Economist’s View of the World (p. 32). Cambridge University Press. Kindle Edition. The college facility is a particularly blunt example. If 10 to 15 minutes extra time is enough to deter you from getting medical appointments, your health is probably not in any serious danger.

“[Economist Michael] Cooper noted that both demand and need tend to grow in line with provision. Doctors react to any expansion in supply by realigning their conception of need. Thus, one study of acute care hospitals found that both admissions and length of stay increased with bed availability. It could not discover a level of bed provision that would have fully satiated doctors’ demands.12” Rhoads, Steven E.. The Economist’s View of the World (p. 34). Cambridge University Press. Kindle Edition.

When younger, I was such a patient, and I would frequently see a sports medicine doctor and a physical therapist about my tennis elbow. They would subject me to electrical stimulation and therapeutic ultrasound therapies. I was never sure that either did anything to get me back on the court any sooner. But I loved tennis, and it was worth $10 a visit (my co-pay) if it might speed up the natural healing process. I would never have paid the full cost of the treatment. My fundamental health was never at issue. Rhoads, Steven E.. The Economist’s View of the World (p. 35). Cambridge University Press. Kindle Edition. A very blunt example of the third-party payer problem!

Even such “needed” things as food and electricity are not immune:

‘When people try to quantify a country’s “need” for this or that product or service, they are ignoring the fact that there is no fixed or objective “need.” Seldom, if ever, is there a fixed quantity demanded. For example, communal living in an Israeli kibbutz was based on its members’ collectively producing and supplying each other with goods and services, without resort to money or prices. However, supplying electricity and food without charging prices led to a situation where people often did not bother to turn off electric lights during the day and members would bring friends from outside the kibbutz to join them for meals. But, after the kibbutz began to charge prices for electricity and food, there was a sharp drop in the consumption of both.{33} In short, there was no fixed quantity of “need” or demand for food or electricity, despite how indispensable both might be.’ Sowell, Thomas. Basic Economics (p. 28). Basic Books. Kindle Edition.

The above list is far from exhaustive. But hopefully I persuaded you that Bryan’s analysis about the wastefulness of gratis pricing is correct.

Even after the CCCP bread was priced so cheaply in RF/UKR/ … that:
a) people kept using it as a side-dish for every type of lunch, even pasta.
b) private pig-farmers in the 90ies loaded their cars with it – the (cheaper) “black” version (actually brown, baked with rye) to feed it to their sows.
c) and there was only one other version than “black”: white (wheat only). Both were tasty – probably inspired by German bread. In villages at times only black, in big cities in good years more choice.
– Nowadays everywhere lots of choice, all same bland taste. 😉 –
Iran still the only country with a working kidney market?
Agree with the other comment: Why is this fine blog free? Why so many others? – Ok, non-rival. But why you (Scott S./Scott A./Robert H./ … ) keep delivering? – Why do we write comments? (ok, that does not produce much positive value – the MR comments negative)
