QUESTION 2 (5 marks) Read the textbook, analyse the issue “Population growth, sustainability and the PPF (pp. 44–5)”, and answer the following questions 1 Draw a production possibilities frontier for an economy that has no immigration. (1 Mark) 2 Explain how a new policy of promoting immigration could shift this nation’s PPF. (1 Mark) 3 Does this shift in the PPF result only from increased resources in the form of new labour, or do other resources and technological change also play a part? Where does the natural environment fit into this picture? (1.5 Marks) 4 Give some thought to the PPF for the countries from which workers are emigrating. Does this emigration affect their production possibilities, and what is its effect on the natural environment in these countries? (1.5 Marks) QUESTION 3 (5 marks) 1 Distinguish between an increase in demand and an increase in quantity demanded. Show each graphically (1 Mark). 2 Explain what will happen to either supply or demand in the following situations a) As a result of the improving economy, several large overseas companies decide to enter the supermarket business in Australia. b) Consumers suddenly decide that tattoos are unfashionable. c) The Department of Employment issues findings of a study that shows that playing computer games increases young people's job prospects. d) Frost threatens to damage the coffee crop, and consumers expect the price to rise sharply in the future. e) The price of air conditioners increases significantly.
