(b) The government can start giving subsidies to the bus commuters of the difference in the prices to encourage them for continuing with the bus services.

Step by step solution

Step 1. Define Externality.

An externality is a consequence of an economic activity that affects the third party. For example, pollution is an externality.

Part (a). The demand-supply analysis.

Widely available bus lines will reduce traffic congestion by decreasing private vehicles. This may lead to external benefits such as transportation costs, pollution, and traffic congestion being reduced.

The use of public buses would increase both the price and the quantity demanded as the external benefit shifts the demand curve right.

Part (b). A government policy.

The government can start giving subsidies to the bus commuters of the difference in the prices to encourage them for continuing with the bus services. The policy of providing subsidies to bus commuters will attract a large crowd owing to the extra revenue they gain.
