A subsidy is a benefit, usually paid or granted by a government, that lowers the cost of producing, buying or doing something for a particular person, business or industry. The benefit can be cash, such as a payment per unit produced, or something with no cash outlay attached, such as a tax break, a below-market interest rate or a government-backed price reduction. In economics, a subsidy works like a negative tax. It moves the price that buyers pay and the price that sellers receive apart, which changes how much of the good gets produced and consumed.

What Is a Subsidy?

The word comes from the Latin subsidium, meaning support or aid: one party absorbs part of a cost so that another pays less or earns more. A subsidized good, loan or service is one whose price to the user sits below what the market alone would charge.

Most discussion of subsidies concerns government programs, because governments are the largest providers and their subsidies are funded by taxpayers. A government subsidy can be aimed at:

• Individuals and households, through welfare payments, unemployment benefits, housing assistance or help with health insurance premiums.
• Businesses and industries, through production payments, tax credits, cheap loans or guaranteed prices.
• Institutions, such as schools, hospitals or public transit systems.

Subsidies are a feature of a mixed economy, since a purely free market would have none. Much of the political argument over subsidies is really an argument over how mixed an economy should be (see capitalism and its alternatives).

Private parties can subsidize too. An employer that covers part of the cost of staff meals, or a company that sells one product at a loss and recovers the money on another (a cross-subsidy), is doing the same thing on a smaller scale. When economists say “subsidy” without qualification, though, they nearly always mean public support.

How a Subsidy Works

Every subsidy either adds money to a transaction or removes a cost from it. Take a production subsidy of a fixed dollar amount per unit. From the producer’s point of view, each unit now earns the market price plus the subsidy, so producers are willing to supply more at any given price. On a supply and demand chart, the supply curve shifts down by the amount of the subsidy. The new equilibrium has a lower market price and a larger quantity.

Worked example (hypothetical)

Assume a market for a good with these simplified, illustrative curves:

• Demand: Qd = 100 - 2P
• Supply: Qs = -20 + 4P

Without a subsidy, set Qd equal to Qs: 100 - 2P = -20 + 4P, so P = $20 and Q = 60 units.

With a $3 per-unit subsidy paid to producers, each seller receives the market price plus $3. Supply becomes Qs = -20 + 4(P + 3) = -8 + 4P. Setting this equal to demand: 100 - 2P = -8 + 4P, so P = $18 and Q = 64 units.

What changed:

Buyers save $2 per unit and sellers gain $1 per unit. The two gains add up to the full $3 subsidy.

Consumer surplus rises by about $124 and producer surplus by about $62, a combined gain of $186, while the government spends $192. The $6 gap is the deadweight loss: the extra 4 units cost more to produce than buyers value them, so society is slightly worse off unless the subsidy corrects some other problem. The $192 is also the subsidy’s opportunity cost: it could have funded something else or been left with taxpayers.

Interpreting the split: who really benefits

In the example, buyers captured two-thirds of the subsidy even though the government paid sellers. That outcome depends on the slopes of the curves, not on who receives the check. In elasticity terms, the approximate share passed to buyers is:

Buyer share = Es ÷ (Es + |Ed|)

where Es is the price elasticity of supply and Ed is the price elasticity of demand. The less price-responsive side captures more of the benefit. If demand is very inelastic, buyers capture most of a subsidy. If supply is rigid, producers keep most of it.

Two practical consequences follow:

1. Paying the buyer or the seller gives the same market result. A $3 subsidy given to consumers at the till would produce the same $18 to $21 price gap and the same 64 units. The legal recipient (statutory incidence) and the real beneficiary (economic incidence) can differ.
2. Subsidies can raise prices elsewhere. If supply is constrained, as with housing in a city that cannot build quickly, a subsidy to buyers can push up the price sellers charge, and much of the benefit ends up with existing owners.

Types of Subsidies

Direct vs. indirect subsidies

Direct subsidies are actual payments of money to a specific person, group or industry. A per-unit payment to farmers, a grant to a manufacturer or a check to an unemployed worker are all direct.

Indirect subsidies have no predetermined cash value and involve no payment to the recipient. Their value shows up as a cost the recipient does not have to pay. Common forms include:

• Tax breaks: credits, deductions, exemptions or reduced rates for a favored activity. Because the government gives up revenue rather than writing a check, these are often called tax expenditures.
• Price reductions: government-supported prices for essential goods or services such as fuel, electricity or food staples, so that buyers pay below the market rate.
• Cheap credit: loans at below-market interest rates, or government guarantees that let a borrower get a lower rate from a private lender.
• In-kind support: free or discounted land, infrastructure, equipment or services.

Indirect subsidies are harder to measure and less visible in budgets, which is part of why critics watch them closely.

Subsidies for individuals

Welfare payments and unemployment benefits support people through financial hardship. Other individual subsidies aim to change behavior. Subsidized student loan interest rates, for example, lower the cost of borrowing for education to encourage more people to continue their studies.

In the United States, the Affordable Care Act made some families eligible for help with health insurance premiums based on income and household size. The money goes to the insurer, which lowers the household’s premium, so the household benefits without ever receiving the cash.

Subsidies for businesses and industries

Business subsidies are often justified as support for a domestic industry facing foreign competition that has pushed prices so low that local firms cannot operate profitably without help. Others aim to accelerate new industries, regional development or research. Historically, most U.S. subsidies have gone to four industries: agriculture, financial institutions, oil companies and utilities.

Production vs. consumption subsidies

A production subsidy lowers costs for producers, as in the worked example. A consumption subsidy lowers the price paid by consumers, for instance by capping retail fuel prices and covering the difference. Both increase the quantity traded, and in energy they stack: G-20 production subsidies averaged about $290 billion a year from 2017 to 2019, 95% of it to oil and gas, while global consumption subsidies in 2019 came to about $320 billion, also driven largely by oil and gas. Subsidizing both sides pushes the price signal down twice, encouraging even more consumption.

Why Governments Use Subsidies

Correcting market failure. When the actual supply of a good falls below the socially optimal level, economists call it a market failure. Subsidizing the undersupplied good lowers producers’ costs and, if set at the right level, can push output back toward the optimum. This is the strongest economic case for a subsidy. In the worked example, the $6 deadweight loss would disappear, and could become a net gain, if the extra 4 units produced benefits the market price did not reflect.

Positive externalities. When an activity benefits third parties who have no say in the decision, buyers and sellers weigh only their own gains, so the activity happens less than society would want. Education, vaccination and basic research are standard examples. A subsidy that closes the gap between private and social benefit is called a Pigouvian subsidy, the counterpart of a Pigouvian tax on negative externalities such as pollution.

Infant industries. Some development theories hold that governments in less-developed economies should support domestic industries while they are young, shielding them from established foreign competitors until they can compete on their own. China and several South American countries are often cited as users of this approach.

Jobs and stability. Supporters argue that subsidies preserve businesses and the jobs they create, especially in regions dependent on a single industry, and that they cushion households against sudden income losses.

Social and political goals. Some subsidies aim at outcomes markets do not price at all: keeping small farms in business, ensuring rural areas have postal or broadband service, or making essentials affordable for low-income households.

Drawbacks and Limitations

They distort prices and resource allocation. Free market economists hold that market forces should decide which businesses survive. When a firm fails, its labor, capital and other factors of production move to more productive uses. A subsidy can interrupt that process and keep resources in an inefficient activity.

They are hard to calibrate. The market failure argument assumes policymakers know the optimal quantity and the right subsidy rate. Critics argue that economic calculation is too imprecise, and microeconomic models too stylized, to measure a market failure accurately. Set the subsidy too high and it creates overproduction, which is the deadweight loss problem from the example on a larger scale.

They often cost more than promised. Some economists argue that subsidy programs routinely fall short of their projected results, and that their costs and unintended effects are rarely worth it.

Someone else pays. Subsidy money comes from taxes, borrowing or higher prices elsewhere.

They attract lobbying. Theories of regulatory capture and rent seeking describe subsidies as a mutually beneficial arrangement: companies seek protection from competition, and politicians receive campaign support or later career benefits. Because a subsidy raises its recipients’ profits while its cost is spread thinly across many taxpayers, recipients usually lobby far harder to keep it than anyone lobbies against it, even after its original purpose has gone.

They are hard to remove. Cheap fossil fuels encourage overconsumption, yet energy subsidy reform faces resistance from consumers who would pay more and companies that would earn less.

Judging Whether a Subsidy Worked

Economists and politicians often reach opposite verdicts on the same program because they use different yardsticks: total economic welfare, the welfare of the targeted group, or a non-economic or political goal. A subsidy that transfers wealth to its beneficiaries and helps its sponsors get reelected can succeed for its backers while being an economic failure over the long run.

The Great Depression offers a clear case. Presidents Herbert Hoover and Franklin D. Roosevelt both set price floors on farm products and paid farmers to limit production. On its own terms (stopping food prices from falling and protecting small farmers) the policy worked. But taxpayers funded it, and artificially high food prices lowered consumers’ living standards, leaving people outside farming worse off in absolute terms.

Subsidy vs. Related Terms

• Subsidy vs. transfer payment. A transfer payment (such as unemployment benefits) moves money to a person without any good or service in return. Many individual subsidies are transfer payments. Business subsidies tied to production or price are not.
• Subsidy vs. grant. A grant is a direct subsidy for a defined purpose, often a project. “Subsidy” is broader and includes indirect support.
• Subsidy vs. tax break. A tax break is one kind of indirect subsidy. It lowers what the recipient owes rather than paying it, with a similar budget effect.
• Subsidy vs. price floor or price ceiling. A price control fixes a legal price without necessarily paying anyone. It becomes a subsidy when the government funds the gap, for example by buying surplus output at a guaranteed price or reimbursing retailers who sell below cost.
• Subsidy vs. tariff. Both can protect domestic producers. A tariff does it by taxing imports, raising prices for consumers. A subsidy does it by supporting domestic firms, usually lowering prices but at taxpayers’ expense.

FAQs

The Bottom Line

Subsidies matter to taxpayers, consumers and businesses because they change prices, output and who carries the cost. Who gains depends on how responsive supply and demand are, so the legal recipient may not be the real beneficiary. A subsidy can correct a market failure or support a social goal, but it can also distort prices, overshoot its target and outlast its purpose once lobbying sets in.
