What Is a Life Worth? The Value of a Statistical Life

How economists estimate the "value of a statistical life" from how much people pay to reduce small risks, why governments use it, and why it's ethically debated.

Governments must decide how much to spend on safety. Economists use the value of a statistical life (VSL).

What it means

VSL isn’t the value of any particular person’s life.
It’s based on how much people are willing to pay to reduce small risks of death.

Example

If each of 100,000 people would pay 100 rupees to cut their risk of death by 1 in 100,000, together they’d pay 1 crore rupees to prevent one statistical death. So the VSL is 1 crore.

Estimation

Wage premiums for risky jobs.
Spending on safety products like helmets.
Surveys.

Uses

Road safety, pollution rules and health policies.
The US uses a VSL of around 13 million dollars in some agencies.

Variation

VSL estimates vary by income; richer countries have higher VSLs, raising ethical debates.

Ethics

Critics say putting a price on life is troubling; supporters say it helps make consistent choices with limited budgets.

The road barrier

A government weighs building a crash barrier that costs 5 crore and is expected to prevent several deaths over its life, using VSL to judge if it's worth it.

Thinking VSL is the price of a person

It reflects willingness to pay for small risk reductions.

Key takeaways

VSL is based on willingness to pay for small risk reductions.
It's estimated from wages, spending and surveys.
Governments use it for safety decisions.
Its use raises ethical debates.
