Explanation:

The effect of a market exchange on a third party who is outside or "external" to the exchange is called an externality or spill over.

Negative externality are negative spill over effects of a transaction, a situation where a third party, outside the transaction, suffers from a market transaction by others.

Internalizing the externality means shifting the burden, or costs, from a negative externality, such as pollution or traffic congestion, from outside to inside (external to internal). This can be done through taxes, property rights, tolls, and government subsidies.

A negative externality exists is the cost of production exceeds private costs

Hence, such negative externality can be internalized through subsidy by the government
