What it means
Bastiat lived from 1801 to 1850 and spent much of his early life as a landowner and local magistrate in France. He turned to writing in his forties, campaigning against tariffs (taxes on imported goods) and supporting free trade after seeing how protection harmed ordinary consumers.
His career as a public writer was short, but his work had lasting influence. His most famous idea appears in an essay called That Which Is Seen, and That Which Is Not Seen.
Bastiat argued that a bad economist looks only at the immediate, visible result of a policy, while a good economist also considers the consequences that cannot be seen. This is the basis of the broken window fallacy, the idea that destroying something does not create wealth, even though the repair work is easy to spot.
Another well-known piece is the Candlemakers' Petition, a satire in which candle makers ask the government to block out the sun to protect their trade. It was written to mock the logic of protecting domestic industries from foreign competition.
The same logic, Bastiat said, would justify banning daylight. He also wrote The Law, which argues that government should protect people's lives, liberty and property and should not be used to favour one group at the expense of another.
Supporters read this as a case for limited government, while critics say it understates the role of the state. Either way, it remains widely read.
For business people, his lasting value is the habit of thinking about unseen costs. Before approving a subsidy, a discount or a new project, it is worth asking what is not being done with the money.
That question is close to what modern finance calls opportunity cost. Bastiat's influence extends to later writers who popularised his ideas, including twentieth century economists who used the seen and unseen contrast in their books.
His writing is often cited in debates about subsidies, public works and trade barriers.
In practice
Real-world examples.
Example
A town council spends $2,000,000 on a new stadium and cites 40 new jobs. A finance officer asks what the $2,000,000 would have produced if used on road repairs or tax cuts, and presents the comparison to the council. She believes the unseen cost is the lower spending in other parts of the budget.
Example
A company runs a half-price promotion and counts 3,000 extra sales as a win. The marketing analyst points out that many of the buyers would have paid full price, so the unseen cost is lost margin on those sales. The result is a sale that looked busy but earned less.
Example
A government considers a tariff on imported steel to protect 5,000 jobs. A manufacturer of steel products explains that higher input costs will raise prices for its customers and may cost jobs in its own factory. Her argument is based on what cannot be seen on the surface.
Formula
Calculation
Net effect of a decision = visible benefit - unseen cost
Suppose a shopkeeper's window is broken and the repair costs $500. The visible benefit is that the glazier earns $500. The unseen cost is that the shopkeeper would otherwise have spent that $500 on a new suit, and the tailor now earns nothing.
Net effect on spending in the community = $500 - $500 = $0. Because the shopkeeper also ends up with just the window she already had, the community is $500 poorer than if the window had never broken.Case study
Seen in the real world.
Calloway Components is a fictional manufacturer that asked its government for protection against cheaper imports. The chief financial officer was asked to prepare the numbers for the lobbying campaign. She realised the visible gain was easy to quantify: higher prices would protect about $4,000,000 of annual sales.
Remembering the seen and unseen idea, she also modelled what the tariff would do to customers. In this illustrative scenario, the buyers of her components would face higher prices on their own products, and some would switch to imports of the finished goods.
The figures showed that the net effect on the wider industry was negative. She recommended that the company spend the lobbying budget on improving efficiency, and the board agreed after reviewing the analysis. The board kept the analysis on file and used the same two-column format of seen and unseen effects for later investment proposals.
Watch out
Common mistakes.
- Quoting the broken window idea to claim that spending on repairs is always wasteful, when the point is that destruction does not add to total wealth.
- Assuming Bastiat opposed all government activity, when he supported a limited role in protecting life, liberty and property.
- Looking only at the jobs or sales a project creates without asking what the money would otherwise have produced.
Questions
People also ask.
When did Bastiat live?
He was born in 1801 and died in 1850, so his best-known work was written in the last few years of his life. He published most of his major work in a burst of writing in the late 1840s.
Is his work still relevant?
Yes. The seen and unseen idea underlies modern thinking about opportunity cost and the full impact of policies. Business schools often use his ideas when teaching cost-benefit analysis.
Where should a beginner start?
His short essay That Which Is Seen, and That Which Is Not Seen is brief, readable and available in many free editions. Reading it takes about half an hour and gives a strong feel for his method.
