All rights reserved. 2-1 Chapter Objectives • • • • • • • • • Definition of economics Central fact of economics The four economic resources Opportunity cost Full employment Full production Productive and allocative efficiency Enabling the economy to grow The law of increasing cost Copyright 2002 by The McGraw-Hill Companies, Inc. All rights reserved. 2-2 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 Copyright 2002 by The McGraw-Hill Companies, Inc. All rights reserved. 2-3 The Central Fact of Economics Is 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 Copyright 2002 by The McGraw-Hill Companies, Inc. All rights reserved. 2-4 Four Economic Resources • • • • Land Labor Capital Entrepreneurial ability Copyright 2002 by The McGraw-Hill Companies, Inc. All rights reserved. 2-5 Land – 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” Copyright 2002 by The McGraw-Hill Companies, Inc. All rights reserved. 2-6 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 Copyright 2002 by The McGraw-Hill Companies, Inc. All rights reserved. 2-7 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 Copyright 2002 by The McGraw-Hill Companies, Inc. All rights reserved. 2-8 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 Copyright 2002 by The McGraw-Hill Companies, Inc. All rights reserved. 2-9 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! Copyright 2002 by The McGraw-Hill Companies, Inc. All rights reserved. 2-10 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” Copyright 2002 by The McGraw-Hill Companies, Inc. All rights reserved. 2-11 Highest Valued Alternative • Options – – – – Watch TV Talk on the telephone Go on a date Study economics Choice made Highest valued alternative • The opportunity cost here is the highest valued alternative that could have been chosen (i.e., study economics) Copyright 2002 by The McGraw-Hill Companies, Inc.

All rights reserved. 2-14 California 1990 - 1997 • Prison guards + 10,000 • College employees - 10,000 Obviously, the opportunity cost of one additional prison is guard is one college employee Copyright 2002 by The McGraw-Hill Companies, Inc. All rights reserved. 2-15 Full Employment • A five percent unemployment rate 1 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 % Copyright 2002 by The McGraw-Hill Companies, Inc. All rights reserved. 2-16 Full Production • An eighty-five to ninety percent utilization rate Copyright 2002 by The McGraw-Hill Companies, Inc. All rights reserved. 2-17 Underemployment of Resources • • • • • • An unemployment rate greater than 5% A capacity utilization rate less than 85% Blue laws Federal and state laws Night and weekend work Discrimination – A phenomenon that has diminished but has not been eliminated entirely – Probably keeps our output 10 -15% below what it could be • If there was truly an efficient allocation of resources Copyright 2002 by The McGraw-Hill Companies, Inc.

This means that by the time you are 48-50 years old, interest on the $385,000 would give you $26,950 annually ($2,246 a month) for the rest of your life.

The opportunity cost of NOT doing this is approximately $1,193,000 Copyright 2002 by The McGraw-Hill Companies, Inc. All rights reserved. 2-36
