Moral Hazard

“Protection from a consequence can change behavior that others cannot observe.”

01 / PLAINLY

What it means, plainly

Moral hazard appears when, after an agreement, one party can change hard-to-observe actions without bearing all their consequences.

02 / CONTEXT

A little more

Moral hazard arises when, after an agreement, one party takes hard-to-observe actions without bearing all their consequences. Coverage, monitoring, and incentives try to preserve protection without erasing responsibility.

03 / WHY IT MATTERS

Why it matters

It helps design protection and responsibility without assuming that coverage makes every person careless.

04 / EXAMPLE

A familiar example

A full warranty may reduce maintenance care when the decision-maker does not pay the later repair cost.

05 / LIMIT

What it does not mean

“Moral” is historical terminology; the model does not diagnose bad ethics or predict that every insured person behaves worse.

06 / NOTICE

Notice it in your day

Take a hypothetical warranty or insurance policy and note which action might change, who can observe it, and who would bear the final cost.

FINAL NOTE

The idea worth keeping

Find which action changes after the agreement, who can observe it, and where the cost lands.

QUESTIONS / 02

Questions people still have

When does a moral-hazard problem arise?

After an agreement, when a hard-to-observe action changes and its consequences do not fully fall on the decision-maker.

Does the term diagnose bad moral character?

No. “Moral” is historical terminology for the model, not a judgment of character.
