Market Failure

Market failure occurs when the price mechanism of supply & demand fails to efficiently allocate resources.

There are a variety of key exam topics highlighting market failure below:

  • Public goods – there is usually not enough public good provided in a free market
  • De-Merit goods – people tend to underestimate the cost of a good. Demerit goods can be addictive; hence consumers continue to buy them, and this causes negative externalities
  • Asymmetric information – when one party possess more information than the other and can use this to their advantage by exploiting the other party
  • Negative and Positive Externalities – goods which cause positive externalities are often under consumed in the economy, whereas goods which cause negative externalities are overconsumed; this is indicated by the welfare loss or welfare gain. This causes market failure as there is a misallocation of resources and potentially a lack of knowledge.
