Sample questions from Market Failure and Government Intervention

Answer each one closed book first, then open the answer.

  1. Private, external and social costs

    Who is the third party when a factory discharges waste into a river?

    Show the answer
    The anglers, water companies and residents downstream, who bear the cost of the pollution without taking any part in the factory's transactions.
  2. Private, external and social costs

    Define welfare loss.

    Show the answer
    Welfare loss is the loss of net benefit to society that results from producing at the free-market level of output rather than at the socially optimal level.
  3. Private, external and social benefits

    Give two external benefits created when a firm trains its workforce.

    Show the answer
    Other employers gain skilled staff when trained workers move on, and higher productivity raises output and tax revenue across the whole economy.
  4. Private, external and social benefits

    Define a merit good.

    Show the answer
    A merit good is one whose consumption yields greater benefits than the consumer realises or values, so it is under-consumed if left entirely to the market.
  5. Externalities in production and consumption

    Give an example of a positive consumption externality.

    Show the answer
    A homeowner restoring a run-down period property, which raises the appearance and the value of the whole street.
  6. Externalities in production and consumption

    Explain what would happen to the price and quantity of petrol if its full external costs were reflected in it.

    Show the answer
    The supply curve would shift up by the value of the external cost, so the price would rise and the quantity bought would fall towards the socially optimal level.
  7. Strengths and weaknesses of the market economy

    Define market failure.

    Show the answer
    Market failure is the failure of a free market to allocate resources efficiently, leaving society's welfare lower than it could be.
  8. Strengths and weaknesses of the market economy

    How does the immobility of labour cause market failure?

    Show the answer
    Workers cannot always move between regions or acquire new skills quickly, so labour remains unemployed in one place while vacancies go unfilled in another.

How the guide is worked

Answering a question from memory stores it far better than reading the answer again. The guide runs that as a fixed procedure on one subtopic at a time, about twenty minutes a session.

  1. Step 1 · Closed book

    Cover the answers. Work through one subtopic and write down what you can. Leave blanks where you have nothing.

  2. Step 2 · Open book

    Go back to the top. Read each printed answer and write it out in full, including the ones you had right.

  3. Step 3 · Closed book again

    Same questions, same order, from memory. The gap between pass one and pass three is the session result.

Read the full method, the return schedule and the research behind it.
