## What is market failure?

Market failure occurs when there is a misallocation of resources.

## What are the two main types of market failure?

Market failure can be complete or partial.

Complete market failure results in a missing market. This happens with public goods due to the free-rider problem.

Partial market failure occurs due to a misallocation of resources. It usually means that a good is over-produced or under-consumed. This can happen due to externalities.
