            The Economic Problem
                                     • Unlimited Wants
                                     • Scarce Resources
                                       – Land, Labour,
                                       Capital
                                     • Resource Use
                                     • Choices

     The Economic Problem
• What goods and services should an
  economy produce? – should the emphasis
  be on agriculture, manufacturing or services,
  should it be on sport and leisure or housing?
• How should goods and services be
  produced? – labour intensive, land intensive,
  capital intensive? Efficiency?
• Who should get the goods and services
  produced? – even distribution? more for the
  rich? for those who work hard?

         Opportunity Cost
• Definition – the cost expressed in terms
  of the next best alternative sacrificed
• Helps us view the true cost of decision
  making
• Implies valuing different choices

Production Possibility Frontiers
• Show the different combinations of goods and
  services that can be produced with a given
  amount of resources
• No ‘ideal’ point on the curve
• Any point inside the curve – suggests
  resources are not being utilised efficiently
• Any point outside the curve – not attainable
  with the current level of resources
• Useful to demonstrate economic growth and
  opportunity cost
