3. a) The use of production possibility frontiers to depict:  opportunity cost (through marginal analysis)  economic growth or decline  efficient or inefficient allocation of resources possible and unobtainable production b) The distinction between movements along and shifts in production possibility curves, considering the possible causes for such changes c) The distinction between capital and consumer goods d) The use of production possibility frontiers to depict the maximum productive potential of an economy e) Consideration of actual vs. potential growth of an economy

4. We will be able to explain opportunity cost We will be able to explain the different factors of production as economic resources. We will be able to discuss and chart production possibility frontiers. Title: What is a production possibility frontier? A-Level Economics

5. Do you work to live or live to work?

6. Britons continue to work the longest hours in Europe. According to the TUC, the UK working week has now crept up to 43.5 hours – three hours longer than the European average. More than four million full-time employees work more than 48 hours a week (700,000 more than did during the 1990s). One in six employees regularly clocks up more than 60 hours a week. It also found 5.26 million Britons work an average of 7.2 hours of unpaid overtime a week. Stress positively correlates with both depression and coronary heart disease (Tennant, 2001, 2000).

7. What is the Opportunity Cost? Why is this relevant? Opportunity Cost The cost of an activity expressed in terms of the next best alternative, which has to be given up when making the choice. Key Term:

8. Production Possibility Curve  This shows the maximum quantities of different combinations of output of two products, given current resources and the state of technology The data below shows the various production possibilities for an economy that produces two goods, cars and television sets. a.Draw the above combinations of products on a graph. Put cars on the vertical axis and televisions on the horizontal axis. b.How many televisions can be produced when car production is 700? How does this change when 550 cars are produced? c.How does your diagram illustrate: a.Choice b.Scarcity? CarsTelevisions 1,0000 800400 600800 4001,200 2001,600 02,000

9. Production possibility frontiers: What is it all about?

11. A production possibility frontier (PPF) shows the maximum possible output combinations of two goods or services an economy can achieve when all resources are fully and efficiently employed Production possibility frontiers: What is it all about?

12. 12 What is a Production Possibilities Frontier (PPF)? A graph that shows the maximum combinations of goods that can be produced when resources and technology are used efficiently

13. 13 For simplicity, lets take a world with only 2 products Lets use beer and pizza (a typical college campus?)

14. 14 A typical PPF has the following shape:. Pizza Beer The curve has a negative slope. The curve is concave to the origin.

15. 15 Shape of the PPF? Why Concave? If PPF a straight line, we have constant opportunity costs If PPF concave, we have increasing opportunity costs

16. 16 Consider a straight line PPF Beer Pizza Beer given up, the opportunity cost, remains constant

17. 17 Concave shape, increasing opportunity costs. Pizza Beer Beer given up, the opportunity cost, is increasing

18. 18 What is the Law of Increasing Costs? The opportunity cost of producing a good increases as more of the good is produced

19. 19 Why does the Law of Increasing Opportunity costs hold? Because resources are not perfectly adaptable to all products

20. 20 All points on the curve correspond to full use of resources. Pizza Beer A B

21. 21 Points outside the the PPF are not feasible with existing resources. Pizza Beer.A.A

22. 22 Periods of unemployment or inefficiency in production correspond to points under the PPF. Pizza Beer.A.A

23. 23 What is the Law of Increasing Costs? The opportunity cost of producing a good increases as more of the good is produced

25. 25 How do we have more of everything? By increasing our resources

26. What could increase the PPF? -  natural resources found -  population (labour) -  technology -  infrastructure for production Production Possibility Frontier

27. 27 Economic growth indicates an increase in the total output of an economy. Pizza Beer.A.A The PPF shifts to the right !

28. 28 Can a PPF shift inward (to the left)? YES!! For just the opposite reasons as an outward shift such as a loss of resources

29. 29 Economic growth and the Capital Consumer goods tradeoff: Consumer goods Capital goods A B From which point would an economy grow faster, A or B?? Answer is A, with more capital goods
