Basic Economic Concepts

Slide 3

Basic Economic Vocabulary Needs are Necessities for survival Wants are Ways of expressing needs and/or goods and services consumed beyond what is necessary for survival. Goods are physical objects that can be purchased Services are actions or activities performed for a fee

Slide 4

Economics is the study of scarcity and choice. We have limited resources and unlimited needs and wants. Every economics issue involves personal choice. Scarcity: there is not enough of it available to satisfy the way a society wants to use it. This leads us to making choices. Opportunity Cost is what is sacrificed when one choice is made over the next best alternative Every decision has an opportunity cost

Slide 5

Opportunity Cost to every decision!

Slide 6

The Six Core Principles of Economics 1.People choose 2.People s choices involve costs. 3.People respond to incentives in predictable ways. 4.People create systems that influence individual choices and incentives. 5.People gain when there is voluntary exchange. 6.People s choices have consequences that lie in the future.

Slide 7

1. People Choose We always WANT more than we can get and PRODUCTIVE RESOURCES (HUMAN, NATURAL, CAPITAL) are always limited. Therefore, because of this major economic problem of SCARCITY, we usually choose the alternative that provides the most BENEFITS with the least COST.

Slide 8

2. People s choices involve costs. All Choices Involve Costs The OPPORTUNITY COST is the next best alternative you give up when you make a CHOICE. When we choose one thing, we refuse something else at the same time.

Slide 9

3. People respond to incentives in predictable ways. INCENTIVES are actions, awards, or rewards that determine the CHOICES people make. Incentives can be positive or negative. When incentives change, people change their behaviors in predictable ways.

Slide 10

4. People create systems that influence individual choices and incentives. People cooperate and govern their actions through both written and un written RULES that determine methods of ALLOCATING scarce resources. These RULES determine what is produced, how it is produced, and for whom it is produced. As the rules change, so do individual CHOICES, INCENTIVES, and behavior.

Slide 11

5. People gain when there is voluntary exchange. People SPECIALIZE in the PRODUCTION of certain GOODS and SERVICES because they expect to gain from it. People TRADE what they produce with other people when they think they can gain something from the EXCHANGE. Some BENEFITS of voluntary TRADE include higher STANDARDS OF LIVING and broader choices of GOODS and SERVICES.

Slide 12

6. People s choices have consequences that lie in the future. Economists believe that the COSTS and BENEFITS of DECISION MAKING appear in the future, since it is only the future that we can influence. Sometimes our choices can lead to UNINTENDED CONSEQUENCES.

Slide 13

Key Assumptions in Economics People are rationally self-interested __They seek to maximize their utility (happy points) People generally make decisions at the margin __They weigh the marginal benefit against the marginal cost of a decision Ceteris Paribus _ Economists hold factors constant, except for whats being considered.

Microeconomics vs. Macroeconomics MICROeconomics (think of small picture) Individual markets The behavior of firms (companies) and consumers Supply and demand Competition Resource markets Market failures

Slide 16

Macroeconomics Examines: (Think of the Big Picture) National Markets Total output and income of nations Total supply and demand of the nation Taxes and government spending Interest rates and central banks Unemployment and inflation Income distribution Economic growth and development International Trade

Slide 17

Eight Economic Goals Economic Growth 1. Economic Growth [Increase in Real GDP or per capita GDP] 3% 3% annual growth will increase our standard of living. 1929-Per capita=$ 792 1933-Per capita=$ 430 2007-per capita= $ 44,000 1929-Per capita=$ 792 ; 1933-Per capita=$ 430 ; 2007-per capita= $ 44,000 Full Employment 95-96 % 2. Full Employment about 95-96 % employment is full 198210.8% employment. In 1982, unemployment was 10.8% [12 M unempl.] Doing the best with what we have. Economic Efficiency 3. Economic Efficiency obtaining the maximum output from available resources or maximum benefits at minimum cost from our limited resources.

Eight Economic Goals In 1945, $1.50 bought what $1.00 did in 1860. Today, it takes $11 to buy what $1 bought in 1945. Price Level Stability 4. Price Level Stability sizable inflation or deflation should be avoided. We had over 10% in 73, 79, & 80. Inflation 2% in the 1950s2.3% in 1960s7.4% in 80s was 2% in the 1950s, 2.3% in 1960s and 7.4% in 80s. A person making $25,000 a year at age 30 would need (with average inflation of 5%) $125,000 a year at age 65 to have the same standard of living. 1972 82, $2.14=$1.00 In 1982, it took $2 to buy what $1 bought in 1972. 2008 1982 2008 1982

Slide 19

Eight Economic Goals A n Equitable Distribution of Income 5. A n Equitable Distribution of Income. One group shouldnt have extreme luxury while another is in stark poverty. The richest 1%(3 mil.) have as much total income after taxes [average $400,000 a year as the bottom 40% [100 million people]. The richest 1% have greater wealth than the bottom 90% of the population.

Slide 20

. E conomic Security 7. E conomic Security provision should be made for those not able to take care of themselves handicapped, disabled, old age, chronically ill, orphans. Protection from lay-offs [unemployment insurance]. Also no discrimination. 43 million Americans have some type of disability. A. Hearing impaired: 22 million (including 2 million deaf) B. Totally blind: 120,000 (Legally blind: 60,000) C. Epileptic: 2 million D. Paralyzed: 1.2 million D. Paralyzed: 1.2 million E. Developmentally disabled; 9.2 million F. Speech impaired: 2.1 million G. Mentally retarded: up to 2.5 million H. HIV infected: 900,000 Economic Freedom 6. Economic Freedom guarantee that businesses, workers, and consumers have a high degree of economic freedom. Balance of Trade $400 billion a year complementaryeconomic growthF.E. ] conflictF.E.price level stability 8. Balance of Trade. O ver $400 billion a year the last few years. Some of these goals are complementary [ economic growth & F.E. ] and some conflict [F.E. and price level stability].

Slide 21

ECONOMICS - science of scarcity choices - the study of the choices people make in an effort to satisfy unlimited needs and wantslimited resources their unlimited needs and wants from limited resources. Individual Choice: Decisions by individuals about what to do, which necessarily involve decisions about what not to do. Think Target and the size of your house.

Slide 22

SCARCITY Marginal decision making = the result of an additional change Marginal benefits vs. marginal costs is the basis for making the decision Examples: 1 more hour of sleep vs. eating breakfast Part time job vs. goofing off College vs. full time job

Slide 23

WHAT IS AND WHAT SHOULD BE: Positive vs. Normative Economics: Positive economics deals with facts and therefore addresses what is. Normative economics attempts to determine what should be based on value judgment. Normative statements express an individual or collective opinion on a subject.

Slide 24

"with other things the same," or "all other things being equal or held constant."
