Question 1

Does 'market failure' mean a company is failing and going bankrupt?

Accepted Answer

No, this is a common misconception. Market failure is not about a firm's profitability. A highly profitable company can be a major cause of market failure if, for example, it creates significant pollution (a negative externality). Market failure refers to the inefficiency of the market outcome from society's perspective, not the commercial success or failure of individual businesses.

Question 2

Are all goods provided by the government 'public goods'?

Accepted Answer

No, and this is a crucial distinction. A 'public good' has specific economic characteristics: it is non-rivalrous and non-excludable (e.g., national defence). Many goods provided by the government, like state education or national healthcare, are not true public goods. They are rivalrous (a place in a class is limited) and excludable (a school could charge fees). These are better classified as merit goods that the government provides to correct under-consumption.

Question 3

If a market is failing, does the government always have to intervene?

Accepted Answer

Not necessarily. Government intervention is only justified if the benefits of the intervention outweigh the costs. Sometimes, government intervention can lead to 'government failure', where the intervention itself causes a more inefficient outcome. This could be due to high administrative costs, political self-interest, or imperfect information on the government's part. Therefore, economists often weigh the potential for government failure against the existing market failure before recommending intervention.
