Economics from Scratch · Part 6
Who Owns What
After Part 5, I tried summing up the series so far: output from labor and capital multiplied by productivity, prices set by supply and demand, money and credit moving resources through time, value as future benefits discounted to today. My first reaction was that this just sounded like capitalism. Where were socialism and communism?
It turned out most of that summary isn’t capitalism. It’s what every economy has to deal with. Only a few pieces are where the systems actually disagree, and understanding them took going back to something more basic: what it means to own a business, and how the answer changes everything the business does.
As before, I’ve kept the questions I had along the way and what cleared them up.
The Problems Every Economy Solves
One person alone on an island decides what to eat, what to build and how hard to work. Scarcity is real: time spent fishing is time not spent building shelter. But there’s no coordination problem, because one person knows everything they need to know.
Scale up to Sam’s town of 10,000 people, and questions appear that nobody can answer alone: how many tutors the town should have, how much bread to bake tomorrow, who gets the scarce spots at the best tutoring center, why anyone would do the hard or boring jobs, and whether to eat the wheat now or plant some for next year. Every economy, of any kind, has to solve the same problems:
| Problem | The question | In Sam’s town |
|---|---|---|
| Information | Who knows what people need, and how best to make it? | Only families know how much they value tutoring. Only Sam knows what her center costs to run. |
| Coordination | How do millions of separate decisions fit together without shortages or waste? | Enough tutors for the students who want them, but not so many that most sit idle |
| Incentives | Why would anyone work hard, take risks, save or invent? | Why would Sam open a center, or Leo take a course to get better? |
| Distribution | Who gets what share of the output? | How the money the center brings in gets split |
| Power | Who decides, and what stops them abusing it? | Who sets the rules for the tutoring market, and who can change them |
| Time | How much to consume now versus invest for later? | Spend this year’s income, or buy laptops that pay off over five years |
A Soviet planner, a Danish politician and an American CEO all face these. The systems are different sets of answers to the same questions.
Two Dials
- Capital: things that were made in order to make other things: machines, buildings, tools, software, computers.
- Means of production: Marx’s term for what produces: the capital, plus usually the land and the businesses themselves.
- Capitalism: the means of production are privately owned, goods are traded in markets, most people work for wages, and owners keep the profit.
- Socialism: the means of production are owned socially, by the state, by the workers who use them, or by communities, so that no class lives off owning capital.
- Central planning: a central authority decides what gets produced, how much, and where it goes, instead of market prices.
Socialism is defined by ownership. How an economy is coordinated, by markets or by a plan, is a separate question, and socialists have disagreed about it from the start. So there are two dials, not one:
| Coordinated by markets | Coordinated by central planning | |
|---|---|---|
| Privately owned | Capitalism, like the US | Wartime economies, where the state directs privately owned factories, like the US and Germany in World War II |
| Socially owned | Market socialism: worker cooperatives, Yugoslavia | Soviet-style planned socialism |
Sam’s center in three corners. Under capitalism, Sam owns the center, sets prices in the market, pays Leo a wage, and keeps the profit. In a worker cooperative, Sam, Leo and the other tutors own it together and split the profit, with prices still set by the market. Under central planning, a ministry decides how many tutoring spots the town gets, what they cost and what tutors earn. There’s no market price.
The planned corner shows the core argument against it. Say the planner fixes tutoring at $75 a month because it seems fair. At $75, 160 families want spots but only 80 exist. Nothing rises to signal “make more,” so you get waitlists, and someone has to decide who gets the spots. This is the knowledge problem, made famous by Friedrich Hayek: prices carry information about what people want and what things cost that no planner can gather.
What Owning a Firm Means
Sam could, in principle, run tutoring without a firm: hire a tutor for each session, rent a room by the hour, negotiate every deal. But every deal takes searching, haggling and checking. In 1937, the economist Ronald Coase pointed out that firms exist because using the market for everything has costs. Inside a firm, instead of negotiating each time, someone just decides: “Leo, you teach the 4 p.m. class.”
So a firm is a group of people and equipment organized under one set of decisions instead of a string of separate deals. Owning one isn’t really about owning desks. It’s two rights:
- The residual claim. Everyone else gets a fixed, agreed amount. The owner gets whatever is left.
- Control. The owner has the final say on anything a contract doesn’t already fix: what to charge, whom to hire, what to buy.
| Who | What they get | Fixed or leftover? |
|---|---|---|
| Leo and the other tutor | $600 each in wages | Fixed, agreed in advance |
| The book supplier | $200 | Fixed |
| The bank that lent her $5,000 | Its interest | Fixed |
| Sam | Whatever is left | Leftover |
In a normal month, $2,000 comes in and Sam keeps about $600. In a great month she might keep $1,000. In a bad month she might keep nothing, while the tutors, the supplier and the bank still get paid in full.
The leftover and the control go together for a reason. The person who keeps the leftover gains when decisions are good and loses when they’re bad, so they have the strongest reason to decide well. If Sam’s choice to buy new laptops pays off, she’s richer. If not, she’s poorer. So:
Whoever owns the firm gets the leftover and makes the decisions, and they make decisions to maximize what they get.
In a worker cooperative, the leftover and the control go to the workers. Two things follow. Their pay is no longer fixed, so it goes up in good months and down in bad ones: the workers now carry the risk Sam used to. And decisions are made to maximize what the workers get, not profit for an outside owner. Those two shifts sound small, but they change how the firm hires, invests and handles risk.
How the Owner Changes the Decisions
A capitalist owner maximizes profit. A worker cooperative maximizes income per member. Start with two tutors, 20 students at $100, and $200 of supplies:
| Sam owns it | The tutors own it as a cooperative | |
|---|---|---|
| Money coming in | $2,000 | $2,000 |
| Supplies | −$200 | −$200 |
| Wages | −$1,200 ($600 each) | None: members take the leftover |
| What the owners get | Sam keeps $600 | $1,800 split two ways = $900 each |
Adding a third tutor. A third tutor would bring in 8 more students, $800, and use $50 more in supplies.
Sam hires if the tutor adds more than they cost: $800 in, $600 wage plus $50 supplies out. Profit rises $150. She hires.
The cooperative adds a member only if it raises income per member. The total to split becomes $1,800 + $800 − $50 = $2,550, or $850 each, down from $900. The members vote no.
The new tutor adds $750 of value, more than the $600 a tutor earns in the market, so the hire is good for the economy. But $750 is less than the $900 each member takes home, so adding them pulls the average down. The capitalist compares the new tutor to the market wage. The cooperative compares them to the members’ current income. So cooperatives tend to hire less, and the tutor who wasn’t added works somewhere else or doesn’t work.
A recession. Only 16 students want tutoring, so $1,600 comes in. One tutor can teach 10 students.
| Sam’s options | Keep both tutors | Let one go |
|---|---|---|
| Money in | $1,600 | $1,000 (one tutor’s limit) |
| Supplies | −$200 | −$100 |
| Wages | −$1,200 | −$600 |
| Sam’s profit | $200 | $300 |
Laying off a tutor earns Sam more, so she lets Leo go. Leo loses his whole income, and the other tutor keeps all of theirs.
In the cooperative, both keep their jobs: ($1,600 − $200) ÷ 2 = $700 each, down from $900. Everyone takes a pay cut instead of one person losing everything. Studies of cooperatives tend to find exactly this: they cut pay rather than jobs in downturns. It’s one of their genuine advantages.
Effort. At Sam’s center, Leo earns $600 whether or not he puts in extra effort, so Sam has to watch and manage. In a cooperative, extra effort raises the leftover everyone shares, so members have a reason to work hard and to keep an eye on each other. That works with two or ten members. With a thousand, each person gets only a tiny share of the gain from their own effort, so the advantage fades, and decisions by vote get slow.
| Decision | Capitalist owner | Worker cooperative |
|---|---|---|
| What it maximizes | Profit | Income per member |
| Hiring | Anyone who adds more than the market wage | Only people who add more than members already earn |
| In a downturn | Lays people off | Cuts everyone’s pay, keeps jobs |
| Effort | Has to monitor workers | Members police themselves, if the group is small |
| Who carries the ups and downs | The owner | The workers |
Neither is simply better. The cooperative is kinder in a downturn and motivates members in small groups. The capitalist firm expands more readily and creates more jobs when there’s work to be done.
Investment and Time
The center could spend $3,000 now on laptops and learning software, raising income by $1,000 a year for 5 years, after which the equipment is worn out.
Sam’s view. A dollar arriving in the future is worth less than a dollar today, so to compare, each future $1,000 gets discounted back to today. At 8% a year, five payments of $1,000 are worth $3,993 today. It costs $3,000, so she invests.
Even if Sam plans to sell in two years, she still invests. A buyer pays for all future profits, so the extra $1,000 a year in years 3 to 5 makes the center worth more, and Sam collects that through a higher sale price. Because she can sell, she gets the full benefit however long she stays.
The cooperative’s view. The $3,000 comes out of this year’s income, so each of the two members gives up $1,500. Each then gets half of the extra $1,000, so $500 a year, but only while they’re still a member. When a member leaves, they can’t sell their place. One tutor plans to stay 5 years. Leo plans to leave in 2.
| The tutor staying 5 years | Leo, leaving in 2 years | |
|---|---|---|
| Gives up now | $1,500 | $1,500 |
| Gets back | $500 a year for 5 years | $500 a year for 2 years |
| Worth today, at 8% | $1,996 | $892 |
| Vote | Yes | No |
The investment is good for the center: $3,993 of value for $3,000. For Leo it’s a loss: he pays $1,500 and gets back $892 of value before he leaves. So he votes no.
That’s the horizon problem: each member only counts the benefits that arrive while they’re still there. The further away the payoff, the less soon-to-leave members care. Across an economy of cooperatives, that means too little long-term investment, which is part of what happened in Yugoslavia.
Outside money doesn’t easily fix it. A capitalist firm short on cash can sell shares to investors. Outside investors would want a share of the leftover and a say in decisions, but in a cooperative those belong to the members. So cooperatives mostly fund investment from members’ pay, or by borrowing, which is how many Yugoslav firms ended up deep in debt.
Successful cooperatives work around it. Mondragon gives each member an individual capital account. When the cooperative reinvests, part of the value is credited to each member’s account and paid back when they retire or leave. That gives Leo back much of the future value he helped create.
Capitalist firms have their own time problem: managers judged on quarterly earnings sometimes skip long-term investments. But a share price reflects all future profits, so owners at least have a way to cash in long-term value today.
Risk
- Risk aversion: most people prefer a steady $600 to a coin flip between $200 and $1,000, even though both average $600. A bad month hurts more than a good month helps, especially when rent is due.
- Diversification: spreading money across many separate bets, so one bad outcome doesn’t sink you.
- Limited liability: if a company goes bankrupt, its shareholders lose what they put in, but nothing more.
Say the center’s leftover each month is equally likely to be $200, $600 or $1,000, an average of $600. Who should carry that?
Leo, in a cooperative. His pay swings with the center’s results. He has one job, so in a bad month he might not make rent. And his skills, his job and his stake are all tied to one center. If it fails, he loses his income and his stake at once.
Sam, as a single owner. Better, if Sam has savings to get through bad months. But her wealth is still concentrated in one center.
Many investors, each owning small slices of many centers. An investor who owns 1/20 of each of 20 centers in different towns sees some bad months and some good ones in any month, and they partly cancel out. The average stays the same, but the swings shrink a lot.
So the same risk is much cheaper to carry for a diversified investor than for Leo. Leo would need a big reward to accept swings in his pay. The investor needs only a small one. That’s why the typical capitalist arrangement looks the way it does: workers get a fixed wage, so in effect the firm insures them against its ups and downs; diversified owners take the leftover and the risk; stock markets split ownership into tiny pieces so millions of people can hold a little of many companies; and limited liability makes it far easier to persuade people to invest. It’s also why cooperatives are rare: they put the risk on the people least able to spread it.
Two limits. Some risk can’t be diversified away: in a recession, every center has a bad month at once. The extra return investors demand for owning stocks over safe bonds, the equity risk premium, is really payment for that economy-wide risk. And separating risk from decisions creates a new problem. If thousands of small shareholders carry the risk, hired managers run the company without carrying much risk themselves. They might take it easy or chase their own goals. That’s the principal-agent problem, and the usual fixes are paying managers partly in company stock and having boards that can fire them. Sam doesn’t have this problem, because she both decides and carries the risk.
| Who carries the risk | Strength | Weakness |
|---|---|---|
| A single owner | The decider bears the result | Owner’s wealth is concentrated |
| Many diversified shareholders | Risk is spread cheaply | Managers aren’t owners |
| The workers, in a cooperative | Members are motivated, jobs are stable | Workers carry risk they can’t spread |
| All of society, through state ownership | The most diversified of all | Nobody deciding personally gains or loses |
In theory, state ownership is the best at carrying risk, because the whole society shares it. It’s the worst at incentives, because no decision-maker feels the result. Almost every arrangement is a trade-off between spreading risk widely and making the people who decide feel the consequences.
The Arrangements Side by Side
Every way of organizing production sets the same dials: who gets the leftover, who decides, what the firm is run to maximize, who funds investment, who carries the risk, whether a money-losing firm closes, and whether decisions are guided by prices or a plan.
| Arrangement | Who owns and decides | Strengths | Weaknesses | Where it thrives |
|---|---|---|---|---|
| Owner-run business | The owner | The decider bears the result | Owner’s wealth concentrated; hard to grow big | Shops, restaurants, small firms |
| Shareholder corporation | Shareholders; hired managers decide | Raises huge sums; risk spread; stakes easy to sell | Principal-agent problem; can chase short-term results | Most large companies |
| Partnership | The senior workers | The owners are the key talent; little capital needed | Hard to raise large sums | Law, accounting, consulting |
| Worker cooperative | All the workers, one vote each | Stable jobs; motivated members | Under-hires, underinvests; undiversified risk; slow decisions | Small, labor-heavy firms with similar members |
| Consumer or producer cooperative | Customers, or suppliers | Serves members, not outside owners | Slower to raise money and expand | Credit unions, farm co-ops |
| Nonprofit | No owners; a board | Trusted where a profit motive could exploit customers | Weak pressure to be efficient | Hospitals, universities, charities |
| State-owned company | The government | Can pursue social goals; risk spread across society | Weak incentives; political interference; rarely allowed to fail | Utilities, railways, national oil companies |
| Central planning | Planners run the whole economy | Can mobilize resources fast for one big goal | Knowledge problem, weak incentives, concentrated power | Wartime production |
The partnerships row is a clue. Law and accounting firms are effectively owned by their workers, and they’re very successful. Worker ownership works when the key asset is the workers’ own skill, little outside money is needed, and the owners are similar enough to agree easily.
The economist Henry Hansmann turned this into a general idea: ownership tends to go to whichever group can own most cheaply. Investors are cheap owners in most industries. They all want the same simple thing, profit, so they rarely disagree. They can diversify. And they can supply the money. Workers usually have mixed goals, can’t diversify, and often can’t fund the firm. Where those problems are small, worker ownership works.
Capitalism, Built From Six Rules
Instead of defining capitalism, it helps to build it. These six rules, taken together, produce a capitalist economy:
| Rule | What it means | Which problem it handles |
|---|---|---|
| 1. Private property | People and firms can own things, including the means of production | Incentives, power |
| 2. Voluntary exchange | People trade only when both sides agree | Distribution, power |
| 3. Market prices | Prices are set by supply and demand, not by an authority | Information, coordination |
| 4. Profit and loss | Owners keep the leftover when they do well and take the losses when they don’t | Incentives |
| 5. Free entry and exit | Anyone can start a business, and failing businesses close | Coordination |
| 6. Capital markets | People can invest in businesses they don’t run, and sell those stakes later | Time |
All six at once. College admissions get tougher and more families want tutoring.
- Families are free to pay more, so the price climbs from $100 to $112.50.
- Sam’s leftover jumps. Nobody told her the town needs more tutoring. The profit is the message.
- A tutor named Ava sees the profits and opens her own center.
- An investor puts $20,000 into Ava’s center for a share of its future profits.
- Ava offers tutors more than they earn elsewhere, and teachers leave other jobs for better pay, which moves people to where they’re most valued.
- More spots exist, so the price drifts back toward $100 and Sam’s extra profit fades. Competition has turned higher demand into more tutoring.
Nobody planned any of it. That’s what Adam Smith called the invisible hand. The reverse happens when an AI tutor arrives: prices fall, some centers lose money, the weakest closes, and its tutors and classroom move to other uses. That’s painful for the people involved, and it’s the part other systems found hardest to allow.
What capitalism needs from outside the market. Capitalism doesn’t mean no government. Private property needs laws, courts and police. Voluntary exchange needs enforceable contracts and a ban on fraud and force. Market prices need stable money. Capital markets need disclosure rules so investors aren’t cheated. Free entry needs competition law, so nobody can block rivals. Where those are weak, capitalism works badly, however free the markets look on paper.
It works best when there’s real competition, buyers know roughly what they’re getting, prices include all the costs, money is stable, and people can recover from losing. Each of those conditions, when it breaks, becomes one of the shortcomings below.
Why Capitalism Is the Most Common System
Capitalism tends to win on six things:
- Information and coordination. Prices carry what millions of people know, with no planner needed.
- Incentives. The people who decide usually bear the result, at least partly.
- Failure works. Bad firms close, and their workers, money and equipment move to better uses. Joseph Schumpeter called new firms replacing old ones creative destruction, and it’s how economies improve.
- Capital for new ideas. Investors fund risky new ventures, can sell their stakes later, and spread their risk across many bets. That’s what funds startups, including today’s AI companies.
- Growth compounds. Small advantages in productivity growth, sustained for decades, become huge differences in wealth. The clearest natural experiments are East and West Germany, and North and South Korea: similar people and history, different systems, very different outcomes.
- It lets the other forms exist. Capitalism doesn’t ban cooperatives, partnerships or nonprofits. They compete alongside shareholder firms, and each wins where it fits best. Planned socialism usually banned the alternatives.
Where It Falls Short, and the Fixes
| Shortcoming | What goes wrong | Common fixes |
|---|---|---|
| Inequality | Gains go to whoever has bargaining power and owns capital, and wealth compounds for those who already have it | Progressive taxes, public education, transfers, broad ownership through retirement accounts, employee ownership, national wealth funds like Norway’s |
| Worker insecurity | Risk moves off owners onto workers’ jobs, so in a downturn people lose everything at once | Unemployment insurance, retraining, portable benefits. Denmark’s “flexicurity”: firing is easy, but support is generous. |
| External costs | Pollution and carbon emissions are costs nobody pays for, so markets make too much of them | Charging for the damage, like a carbon tax, or regulating it directly |
| Monopoly | Some firms get big enough to set prices and block rivals, capturing value without creating it | Antitrust law, blocking mergers, open standards |
| Instability | Booms, busts and financial crises, often driven by expectations running ahead of reality | Central banks, deposit insurance, bank capital rules, automatic support in recessions |
| Public goods | Things everyone benefits from but nobody can charge for, like basic research or clean air, get underprovided | Government funding for research, infrastructure, public health |
| Hidden information | When sellers know much more than buyers, as with insurance or used cars, markets work badly | Disclosure rules, licensing, minimum standards |
Each fix turns a dial partway toward the other side, and each has its own costs. Taxes can weaken incentives. Regulators can be captured by the industries they regulate. Bailouts soften the budget constraint that makes capitalism work. So the real debate in rich countries isn’t capitalism versus socialism. It’s how far to turn each dial, and which costs are worth paying.
AI looks set to push on three of these at once: inequality, if AI capital captures more of the value; worker insecurity, if jobs change faster than people can adjust; and monopoly, since training frontier models takes enormous scale. Which fixes a society chooses may matter as much as the technology.
What’s Next
Every economy solves the same problems: information, coordination, incentives, distribution, power and time. Capitalism and socialism differ on two dials, ownership and coordination. Owning a firm means getting the leftover and making the decisions, and whoever owns it runs it for themselves, which changes hiring, investment and who carries risk. Capitalism is common because it’s strongest on information, incentives, failure and funding new ideas, and because it lets other arrangements compete inside it. Its weaknesses, inequality, insecurity, external costs, monopoly and instability, are what mixed economies try to fix.
These arrangements didn’t appear from nowhere. Part 7 goes back through history, from ancient empires to the Industrial Revolution, to see how each economic system arose, what Adam Smith and Karl Marx actually argued, and why their debate still frames how we think about all this.
