Drinking culture is very prominent in Australia. The country has been known as the beer-drinking nation of the world. The citizens spend approximately $14.1 billion on alcohol per year. However, The Telegraph reports that in the recent years, the Australians are choosing wine over beer, and also the level of consumption is decreasing as the Australians are choosing healthy living (Pearlman, 2015). The government of Australia may impose policies to reduce the alcohol consumption to decrease the negative impact on health. Higher excise tax and price flooring are two such policies. However, the price elasticity of demand for alcohol needs to be estimated before evaluating the impacts of these policies by the government.
1 bottle (700 ml) | Australia ($) | other country on average |
Whiskey | 37 | 25.33 |
Vodka | 37 | 19.99 |
Beer | 17.99 | 9.79 |

Australia has quite higher price of alcohol than in other countries. In spite of the higher cost, the consumption level of alcohol is high in Australia. The demand is not dependent on the price of alcohol. It is assumed that the alcohol consumption primarily depends on the tastes and preferences of the consumers. Thus, 1% increase in the price of alcohol does not have much effect on the demand for alcohol (Jiang et al., 2016).
If, P1 = $17.99, Q1 = 700 ml; and P2 = $20.99, Q2 = 700 ml,
Then, price elasticity of demand for alcohol, Ep =
Therefore, it can be said that, demand for alcohol is inelastic of price. Customers would still prefer to buy the same quantity even if the price rises.
Excise tax is an indirect tax. It is imposed on the sale of a good. The producers shift this tax burden to the customers by raising the price of the product. As the elasticity of price is zero for alcohol, the effect of excise tax is borne by the consumers. They willing pay the higher price to avail the same quantity of alcohol (Sornpaisarn, Kaewmungkun & Rehm, 2015).
Figure 1 depicts the effects of excise tax on the sale of alcohol. As the demand for alcohol is price inelastic in Australia, the demand curve is vertical. The government imposes excise tax of amount t per unit of the product. Due to this, the supply curve shifts upward from S1 to S2, and price increased by the tax amount t, from P1 to P2. As a result of price hike, the producers reduce their supply. However, consumers still demand the same quantity of alcohol, so quantity remains at Q, but new price is P2, which is higher than the previous price P1, by the amount of t per unit. Thus, excise tax only increases the price of alcohol but does affect the demand for it.
When the government imposes minimum prices on the producers, it is known as price flooring. It is a type of price control. Price floor must be higher than the market equilibrium price for effectiveness. When it is imposed, the sellers cannot charge any price below it. To reduce over-consumption of any product, the government sometimes impose minimum price (Mishustin, 2016).
Figure 2 represents the impacts of price floor. The demand for alcohol is price inelastic in Australia. Hence, it has a vertical demand curve. The market equilibrium is at price P* at quantity Q*. When the government imposes price floor, that is, minimum price, the price of alcohol rises to Pf from P*. Therefore, producers increase the supply of alcohol in the market, represented by ES in the figure. This would lead to unsustainable market (Sharma, Etilé & Sinha, 2016). The sellers cannot ask for a lesser price to reach equilibrium and this may lead to market failure. To prevent this situation, either the government would have to buy the surplus production or the sellers have to absorb it (De Vroey, 2016).
The above discussion infers that the imposition of excise tax on the sale of alcohol has greater impact than the imposition of minimum price. In case of inelastic demand, price floor leads to market failure. However, the demand or consumption of alcohol remains unchanged in both the cases. Although, the revenue of the government increases due to excise taxes, and that can be used for the purpose of public spending. On the other hand, the impact of price floor affects the producers and not the customers. Therefore, in the case of inelastic demand, the effect of excise tax is higher than that of price floor (Grossman et al., 2013).
Figure 3 depicts the long run equilibrium of the table manufacturer. The lowest point of his long run average cost curve (LRAC) gives the price of P1, where long run marginal cost (LRMC) cuts the LRAC curve from below. Here P1 = $200. The long run price under monopolistic competition occurs at the point L, where LRAC is equal to AR or demand curve (D), and LRMC is equal to marginal revenue (MR). Thus, the profit maximizing price for the table manufacture would be P*, which is more than P1 = $200 (Vargas, Costa & do Val, 2016).
Oligopoly is a form of the market, characterized by few large sellers, many buyers and differentiated products (Baumol & Blinder, 2015). The features of oligopoly are:
In Australia, three major oligopolistic industries are Banking, Grocery retail and Telecommunication. Four banks, ANZ, NAB, Westpac and Commonwealth Bank dominate the banking sector. In the grocery retail, Woolworths and Coles are market giants. Telecommunication sector is dominated by Telstra, Optus and NBN Co (Dimech, 2014).
These sectors have few but large firms and many buyers. The products are slightly differentiated, hence, non-price competition is widely practiced in this market. The firms act like a group, thus, a decision of one firm affects the decision of the others. There is no price war, as that would bring loss for all firms in the respective industries. If Woolworths goes for a reduction in grocery price to grab more customers, Coles would lower its prices too, to retain the market share. These firms are already so established and have effective pricing, which creates barriers to entry for a new firm in all these industries.
Monopolistic competition is a form of imperfect competition. This market structure is characterized by the presence of many buyers and many sellers, with products that are close, but not perfect substitutes. Here, a single firm does not have the power to control the market price (Varian, 2014).
The features of monopolistic competition are:
The industries, such as, consumer goods, restaurant business and beverage are monopolistically competitive in Australia (Balistreri & Rutherford, 2013). All these sectors have many buyers and many sellers. They sell differentiated products; hence, the intensity of non-price competition is too high. The prices of one firm has little effect on the decisions of the other firms, hence, they can take independent decisions. There is free entry and exit for the firms, without incurring much cost. There is lack of perfect knowledge among the buyers about the products in the respective sectors (Kollmorgen, 2016).
Duopoly is a simple form of oligopoly market structure. It consists of only two sellers and many buyers. Natural duopoly occurs when there is no third seller in the market, differentiated products leading to some monopoly power, and independence between two firms.
In duopoly, a major economic model is Cournot model, which plots reaction curves of the firms in the diagram. It represents the profit maximizing output of one firm and the output expected to be produced by the other firm. The output of one firm is the decreasing function of the production of another firm (Moulin, 2014).
The Cournot equilibrium for natural duopoly. Q1 is the output of firm 1 and Q2 is the output of firm 2. The reaction curves represent the quantity produced by one firm as a function of the expected output of the competitor. In the diagram, point E* is the Cournot equilibrium. It reflects the combination of output, which both the firms produce for profit maximization by predicting the output level of the other correctly. Here, firm 1 will produce 60 units, if firm 2 produces 120 units for profit maximization. Therefore, at this situation, it is difficult for another new firm to enter the market and make profit.
