A significant increase in the price of coffee beans, a key ingredient in coffee production, has prompted some consumers to switch to tea. Which of the following factors affecting price elasticity of demand best explains this consumer behaviour?
Degree of necessity, as consumers view coffee as a luxury item.
Availability of substitutes, as tea provides an alternative beverage option.

The Australian economy is constantly evolving. The main instrument for allocating resources is the market, but government also plays a significant role in resource allocation. In this unit students investigate the role of the market in allocating resources and examine the factors that affect the price and quantity traded for a range of goods and services. Students develop an understanding of the key measures of efficiency and how market systems might result in efficient outcomes. Students consider contemporary issues to explain the need for government intervention in markets and why markets might fail to maximise society’s living standards. As part of a balanced examination, students also consider unintended consequences of government intervention in the market. Students develop an understanding of the macroeconomy. They investigate the factors that affect the level of aggregate demand and aggregate supply in the economy and apply theories to explain how changes in these variables might affect achievement of domestic macroeconomic goals and living standards. Students assess the extent to which the Australian economy has achieved these macroeconomic goals during the past two years. Australia’s living standards depend, in part, on strong economic relationships with its major trading partners. Students investigate the importance of international economic relationships and the effect of these on Australian living standards. Students analyse how international transactions are recorded, and examine how economic factors might affect the value of the exchange rate, the terms of trade and Australia’s international competitiveness. Students also analyse how changes in the value of the exchange rate, the terms of trade and international competitiveness affect the domestic macroeconomic goals.
In this area of study students investigate the role of the market in addressing the key economic questions of what and how much to produce, how to produce and for whom to produce. Students consider the effects of decisions made by consumers and businesses on what goods and services are produced, the quantities in which they are produced, the way they are produced and to whom they are distributed. Students investigate the key factors that affect the level of demand and supply in markets and how these might lead to changing prices, as well as the movement of land, labour and capital resources to those areas of production that generate the most value for society. Students use models to make predictions and consider the role of markets in achieving economic efficiency. They discuss instances where the market fails to allocate resources efficiently and evaluate whether government intervention leads to a more efficient allocation of resources in terms of maximising society’s living standards.
