Minimum price on alcohol
Governments in Australia and around the world are considering implementing a minimum price (aka
price floor) on alcohol. Your task is to use the Economic way of thinking learnt in class to formally
explain the effect of the minimum price. You will need to consider the external effects (negative
externalities) of alcohol consumption, the price elasticity of demand, and taxation (an alternative way
of reducing alcohol production/consumption). To simplify analysis, please assume that alcohol is a
single homogenous good. That is, do not differentiate between different types of alcohol and
packaging (wine, beer, casked wine, spirits etc.).

Questions:
1. Using demand and supply for alcohol, explain why the market outcome may not be efficient.
[Think about externalities. What are some of the external costs imposed on society from
excessive alcohol consumption?] [20 marks] 2. Explain how a well enforced price floor could affect the market for alcohol and how
consumption could adjust to an efficient level. [You can assume that firms understand market
demand and will only produce the amount demanded at the price floor.] [20 marks] 3. Now suppose that instead of using the price floor to restrict consumption, the government
decides to impose a tax on alcohol ($x on each unit of alcohol sold).
a. Can such a tax achieve an efficient level of consumption? Explain. [15 marks] b. In light of your answer to part a, if you were advising the government, would you
recommend implementing a price floor or tax to achieve the efficient level of
consumption? [Hint: think about tax revenue.] [15 marks] 4. Is the demand for alcohol elastic or inelastic? Explain. How are your answers to Question 2
and 3 affected by the price elasticity of demand? [15 marks] 5. Suppose that changing climate increases the price of hops (an input in the production of
alcohol). How will this affect the market for alcohol? Assuming that the price floor or tax on
alcohol sales is operating, what does the government need to do in order to maintain an
efficient level of alcohol consumption? [15 marks]
