Market Failure

  • Adverse outcome: supply and demand fail to achieve balance \(\implies\) Inefficient distribution
  • Theory \(\implies\) two forces balance ideally \(\implies\) production will match demand, prices rise and fall to maintain equilibrium
    • Balance disrupted in market failure.
  • Complete (no market exists) vs partial (market exists wrong quantity/wrong price)

How?

  • Inefficient distribution \(\implies\) individuals end up worse off than not acting in rational self-interest (it's that bad!)
  • Overall group \(\to\) too many costs, too few benefits
  • Economic outcomes deviate from optimal

  • Market failures in government activity

    • rent-seeking by special interest groups
    • each small group imposes costs
  • Correcting the imbalance

    • Government intervention
    • Private-market actors
  • Not all market failures have a potential solution

Causes (EICPG)

Remember as Externalities Inform Control to Public Goods

Many types of imbalances

  1. Externalities
    • Consumption or service harms a third part
    • Pollution from production
    • Negative externalities \(\implies\) Collateral damage \(\implies\) market failure
  2. Information Failure
    • Partial information
    • Buyer/seller lacks info on which price is based \(\implies\) overpay or undercharge
  3. Market control
    • One party with too much control \(\implies\) imbalanced pricing
    • Monopoly/Oligopoly (single or small group) manipulate pricing
    • Monopsony/Oligopsony buyers have advantage
  4. Public goods
    • Defy the tenets of supply and demand
    • Nonexcludable: everyone has access, consumption cannot be limited only to those paying for it
    • Nonrival: use by one individual doesn't limit consumption by others
    • Private sector has less incentive to produce public goods \(\implies\) Govt has to produce or subsidize their production

Solutions

  • Private Market Solutions
    • A solution may emerge from the private market itself
    • e.g. Asymmetrical Information (Securities)
      • Intermediaries/Rating agencies: Moody's and Standard & Poor's
      • inform market participants about security risk
    • e.g. Asymmetrical Information (Electronics)
      • Underwriters Laboratories LLC
    • e.g. Negative Externalities (Pollution)
      • Tort Lawsuits to increase opportunity costs for polluter
    • e.g. Public Goods (Non-excludability)
      • Radio broadcast elegantly solve non-excludable problem
      • Package paid ads with the free broadcast (so someone is paying)
  • Government-imposed Solutions
    • No solution from market \(\implies\) Government enters
    • e.g. Business hire too few low-skilled workers after min wage increase
      • government creates exceptions for less-skilled workers
    • Impose tax and subsidies
      • Subsidies encourage behavior \(\implies\) positive externalities
      • Taxation cut down negative behavior \(\implies\) e.g. tax on tobacco \(\implies\) increased cost of consumption \(\implies\) more expensive to smoke \(\implies\) Smoking is harder (discouraged)
  • Collective action solutions
    • Parties privately
      • agree to limit consumption
      • enforce rules among themselves
      • to overcome tragedy of the commons (= Social or political problem where each individual in incentivized to act in such a way that will ultimately be harmful to all individuals1)
    • Consumers and producers
      • form co-ops to provide services that would be underprovided in a pure market
      • e.g. Electric service to rural homes
      • e.g. Cooperatively held refrigerated storage facility for groups of dairy farmers to chill their milk at an efficient scale

        Recurring theme: Disrupted balance of supply and demand


  1. for personal gain, people deplete shared (common) resources. Exploitation, underinvestment and eventually depletion, e.g. extinction of dodo bird
