2. Objectives The definition of economics The central fact of economics The four economic resources The concepts of opportunity cost, full employment, full production, and productive efficiency What enables the economy to grow The law of increasing cost 2-2 Copyright  2005 by The McGraw-Hill Companies, Inc.

3. Economics Defined Economics is the efficient allocation of the scarce means of production toward the satisfaction of human wants –The means of production are limited –Human wants are unlimited 2-3 Copyright  2005 by The McGraw-Hill Companies, Inc. All rights reserved.

4. The Central Fact of Economics: SCARCITY Scarcity –Resources are the things society uses to produce goods and services These resources are scarce (limited) The economic problem –There are never enough resources to produce all of the goods and services that people want 2-4 Copyright  2005 by The McGraw-Hill Companies, Inc.

5. Four Economic Resources Land Labor Capital Entrepreneurial ability 2-5 Copyright  2005 by The McGraw-Hill Companies, Inc. All rights reserved.

6. Land Land (a broader meaning than our normal understanding of the word) –Includes natural resources such as timber, oil, coal, iron ore, soil, water, as well as the ground in which these resources are found –Is used for the extraction of minerals and farming –Provides the site for factories, office buildings, shopping centers, homes, etc. –Produces “rent” 2-6 Copyright  2005 by The McGraw-Hill Companies, Inc. All rights reserved.

7. Labor –The work and time for which one is paid is what economists call “labor” –Money received for one’s labor is called wages and/or salaries –About two-thirds of the total resource cost is the cost of labor 2-7 Copyright  2005 by The McGraw-Hill Companies, Inc. All rights reserved.

8. Capital –Man-made goods used to produce other goods or services is what economists call “capital” Examples are office buildings, stores, and factories –The money owners of “capital” receive is called “interest” –Capital is the MOST important of the four economic resources 2-8 Copyright  2005 by The McGraw-Hill Companies, Inc. All rights reserved.

9. Entrepreneurial Ability The entrepreneur –Sets up a business –Assembles the needed resources –Risks his/her own (or borrowed) money –Makes a “profit” or incurs a “loss” Is central to the American economy –23 million businesses are virtually all entrepreneurs The vast majority work for themselves or have one or two employees 2-9 Copyright  2005 by The McGraw-Hill Companies, Inc.

10. Our Economic Problem Revisited Limited resources versus unlimited wants There are NOT enough resources to produce everything that everyone wants Therefore, CHOICES must BE MADE! Every choice has an “opportunity cost” associated with it! 2-10 Copyright  2005 by The McGraw-Hill Companies, Inc. All rights reserved.

11. Opportunity Cost: An Important, Fundamental Concept in Economics Because we cannot have everything we want, we must make choices The thing we give up (our second-best choice) is called the opportunity cost of our choice –This is the foregone value of the next best alternative In the economic world, “both” is not an admissible answer to a choice of “which one” 2-11 Copyright  2005 by The McGraw-Hill Companies, Inc. All rights reserved.

12. Highest Valued Alternative Options –Watch TV –Talk on the telephone –Go on a date –Study economics Opportunity cost is the highest valued alternative that could have been chosen (i.e., study economics) Choice made Highest valued alternative 2-12 Copyright  2005 by The McGraw-Hill Companies, Inc.

13. Inherit $40,000 Bought the car –(Paid $40,000) Can’t go to college College graduate (lifetime earnings) $1,300,000 High School graduate (lifetime earnings) 800,000 Two choices – buy a car or go to college Opportunity Cost $ 500,000 2-13 Copyright  2005 by The McGraw-Hill Companies, Inc. All rights reserved.

14. California 1967-1997 Prisons –Added 21 additional prisons Colleges –Added 1 additional college The Opportunity Cost of building more prisons is building fewer colleges 2-14 Copyright  2005 by The McGraw-Hill Companies, Inc. All rights reserved.

15. California 1990 - 1997 Prison guards – + 10,000 College employees – - 10,000 Obviously, the opportunity cost of one additional prison guard is one college employee 2-15 Copyright  2005 by The McGraw-Hill Companies, Inc. All rights reserved.

16. Full Employment Five percent unemployment rate 1 From 1971 – 1996 the unemployment rate was above 5%. In recent years, this has hovered above 4 %. If it stays this low, the next edition of the textbook may adjust this to 4 % 1 2-16 Copyright  2005 by The McGraw-Hill Companies, Inc. All rights reserved.

17. Full Production Eighty five to ninety percent utilization rate 2-17 Copyright  2005 by The McGraw-Hill Companies, Inc. All rights reserved.

18. Underemployment of Resources An unemployment rate greater than 5% A capacity utilization rate less than 85% Discrimination –A phenomenon that has diminished but has not been eliminated entirely –Probably keeps our output 10 - 15 percent below what it could be If there was truly an efficient allocation of resources 2-18 Copyright  2005 by The McGraw-Hill Companies, Inc.

Production Possibilities Curve This is known as the “law of increasing cost.” As the output of one good expands, the opportunity cost of producing additional units of this good increases. As we shift from butter to guns, we have to give up increasing units of butter for each additional unit of guns

27. When you are on the curve, to get more of one thing you have to give up some of the other thing When you are at a point that is inside the line (PPF) it is possible to get more of both If you were at point G, it would be possible to move to point D or any other point on the line (PPF) and get more butter and more guns 2-27 Copyright  2005 by The McGraw-Hill Companies, Inc.

28. Points Inside and Outside the Production Possibilities Curve Frontier Every point on the curve represents output at Full Employment and Full Production Every point inside the curve represents output at less than Full employment and less than Full Production 2-28 Copyright  2005 by The McGraw-Hill Companies, Inc. All rights reserved. Where we usually are A Recession A Depression Point W represents output at more than full employment and full production and is currently unattainable

29. Productive Efficiency Is attained when the maximum possible output of one good is produced, given the output of other goods –Productive efficiency occurs only when we are operating on the production possibilities curve –Productivity efficiency means that the output of one good cannot be attained with out reducing the output of some other good 2-29 Copyright  2005 by The McGraw-Hill Companies, Inc.
