Study Notes

Market Failures and Solutions in Economics

  • Public goods suffer from the free-rider problem, where individuals have no incentive to pay for goods they cannot be excluded from consuming.
  • Pure public goods have non-rivalry and non-excludability, while pure private goods have neither.
  • Options to deal with public goods include public production, public finance and private production, private market solutions, and private cooperation.
  • Information asymmetry leads to opportunistic behavior, such as adverse selection and moral hazard, causing market failure.
  • Externalities, which are the impact of individuals' actions on others, can lead to market failure and require government intervention.
  • There are four types of externalities: negative production, negative consumption, positive production, and positive consumption.
  • Negative externalities lead to overproduction, while positive externalities result in underproduction in the market.
  • The education sector is an example of a positive externality, where government intervention is needed to provide subsidies or the service itself.
  • Pollution by an aluminum factory is an example of a negative externality, requiring solutions such as Pigouvian taxes, cap-and-trade permits, regulations, or voluntary agreements.
  • Property rights can help internalize externalities, but creating markets for them is not straightforward due to the free-rider problem.
  • The Paris Agreement aims to limit global warming by slashing emissions by 43% by 2030, requiring international cooperation and government intervention.
  • UN Climate Review in September 2023 emphasizes the need for drastic global emission reductions to avoid dangerous climate change.
