AS Micro Multiple Choice: Statements about Market Failure

The exam question provides four statements

• A Small firms are less efficient than large firms due to diseconomies of scale.
• B The existence of free riders will result in the over-production of public goods.
• C The social benefits of some private goods exceed the private benefits.
• D Markets do not supply merit goods.

The right answer is C

• A Small firms are less efficient than large firms due to diseconomies of scale - incorrect - small firms are likely to be less efficient because of economies of scale
• B The existence of free riders will result in the over-production of public goods - incorrect - the free rider problem is likely to cause an under-production or non-production of public goods because free riders can consume and benefit without paying
• C The social benefits of some private goods exceed the private benefits - correct! - this statement refers to positive externalities from consumption, for example merit goods such as health care, education and the cultural arts
• D Markets do not supply merit goods - incorrect - markets do provide merit goods (think about private health care!) but they tend to be under-consumed in a market economy
