9708/21/O/N/22 

• Explain, with the use of a diagram(s), how the production possibility curve of an economy could be affected by a decrease in the quantity of labour available, but an increase in its quality. [8] 

9708/22/O/N/22 

• Explain how a production possibility curve can be used to demonstrate scarcity, choice and opportunity cost. 

9708/22/F/M/22 

• Explain with the help of a production possibility curve diagram(s) how a decision to re-allocate resources in an economy to produce more capital goods and fewer consumer goods would affect consumers in both the short run and the long run. [8]

9708/22/O/N/21 

• Use a diagram(s) to explain how a production possibility curve can be used to show opportunity cost and why such a curve is usually drawn with increasing opportunity costs. [8]  

9708/21/O/N/21 

• With the aid of a diagram, compare what happens to an economy’s resources to cause a movement along its production possibility curve with what happens to an economy’s resources to cause a shift of its production possibility curve. [8] 

9708/22/M/J/20 

• Use a production possibility curve diagram(s) to distinguish between the growth of an economy and a reduction in the number of unused resources in an economy and explain one reason that might cause each to occur. [8] 

9708/21/M/J/20 

• Explain, with the aid of a production possibility curve (PPC) diagram, why scarcity makes choice inevitable for firms and how each choice has an opportunity cost. [8] 

9708/21/M/J/19

• Explain, with the help of diagrams, how (i) constant and (ii) increasing opportunity costs determine the shape of an economy’s production possibility curve. [8] 

9708/22/F/M/19

• Show how a production possibility curve can be used to explain scarcity, choice and opportunity cost. [8] 

9708/21/O/N/18

• Discuss whether enterprise is crucial to the outward shift of the production possibility curve in a mixed economy. [12] 

9708/21/O/N/17 

• Use production possibility curves to explain the different impact on an economy of a rise in the unemployment rate and an increase in the working population. [8]

9708/22/O/N/17

• Show the difference between a movement along, and a shift in, a production possibility curve. Explain what might cause each to occur. Use diagrams to support your answer. [8]

9708/23/O/N/17

• Explain how a production possibility curve with increasing opportunity costs illustrates the consequences of a government’s choice to produce more military goods. Use a diagram to support your answer. [8]

9708/23/M/J/13

• With the help of a diagram, explain how a production possibility curve can illustrate the concepts of opportunity cost and economic growth. [8]
