Slide 1

Scarcity and the Science of Economics We witness scarcity with each years hot new product.

Slide 2

Scarcity: Condition where unlimited human wants face limited resources. Effects almost every decision we make.

Slide 3

The study of how people try to satisfy wants with scarce resources. Economics is about scarce resources, consumption and production. How many "economic elements" can you identify in the picture above?

Slide 4

Need: Required for survival. Want: Desired for satisfaction.

Slide 5

Because resources are limited, virtually everything we do has a cost. Someone has to pay for production TINSTAAFL Why do you think scarcity is an issue with the rich as well as the poor?

Slide 6

What To Produce: A society must choose based on its needs. How To Produce: Society must choose based on its resources. For Whom to Produce: Society must choose based on its population and other available markets.

Slide 7

Land: Limited natural resources not created by humans (climate, fresh water, vegetation, minerals, animals) Capital: Means by which something is produced (money, tools, equipment, machinery, and factories).

Slide 8

Labor: Workers who apply their efforts, abilities, and skills to production. Entrepreneur: Risk-takers who combine the land, labor, and capital into new products.

Slide 9

When all the factors of production are present, PRODUCTION, or the process of creating goods and services, takes place.

Slide 10

Describes economic activity- Gross Domestic Product (GDP), unemployment rate, government spending, tax rates Analyzes economic activity and answers the whys and hows-why prices go up and down, or how do taxes affect savings.

Slide 11

Economists offer an explanation of the economy and its activities to the societys population. Prediction: We want to know whats around the corner to better prepare ourselves for the unknown. Will prices rise or fall? Will income increase or decrease? Economics is a social science because it looks at the decisions people make and how they react to those decisions.

Slide 12

Basic Economic Concepts 20% of the worlds people who live in the wealthiest nations consume 86% of the worlds goods and services. The 20% who live in the poorest nations consume only 1.3%

Slide 13

Goods: Item that is economically useful or satisfies an economic want. Consumer good: Intended for final use by individuals Capital goods: Manufactured goods which are used to produce other goods and services. Ex.? Durable goods: Any product that lasts longer than 3 years when used on a regular basis. Ex? Nondurable goods: Any product that lasts less than 3 years when used on a regular basis. Ex?

Slide 14

Services: Work that is performed for someone and intangible. Consumers: A Person who uses goods and services to satisfy wants and needs. Why do you think the U.S. has been described as a society of consumption?

Slide 15

Value: A worth that can be expressed in dollars and cents. Scarcity by itself is not enough to create value. For something to have value, it must also have utility.

Slide 16

Utility: Provide satisfaction, which varies with the needs and wants of each person.

Slide 17

The accumulation of goods that are tangible, scarce, useful, and transferable from one person to another. A nations wealth is comprised of all items, including natural resources, factories, etc. Does not include services!!

Slide 18

Adam Smiths 1776 book, The Wealth of Nations, referred specifically to the ability and skills of a nations people as a source of its wealth. Advocated a free market economy as more productive and more beneficial to society. Comments? Criticisms?

Slide 19

Wealth that is generated by the economy is made possible by a circular flow of economic activity.

Slide 20

Factor Markets Individuals earned income Focus on the four factors of production: land, labor, capital, entrepreneurship Product Markets Individuals spending place Focus on goods and services

Slide 21

Slide 22

Measure of the amount of output produced by a given amount of input within a certain time Productivity increases with efficient use of scarce resources.

Slide 23

May improve productivity because they lead to more proficiency (and greater economic interdependence)

Slide 24

Economic Growth: Depends on high productivity An economys productivity may be affected by

Slide 25

We rely on others, and others rely on us, to provide the goods and services that we consume.

Slide 26

Catch a man a fish, and you can sell it to him. Teach a man to fish, and you ruin a wonderful business opportunity.

Slide 27

Alternative Choices when making economic decisions Decision-making grid lists the adv./disadv of each choice. Criteria:How to spend my $50 gift card?!? AlternativesCost $50Durable?Will parentsFuture expenseCan use or less? approve?unnecessary?anytime? Several CDsyes no Concert Tixno MP-3 playeryes no Hackey sackyes noyesno Jeansyes

Slide 28

The cost of the next best alternative among a persons choices. The cost may be the money, time or resources a person gives up, or sacrifices, to make his/her final choice. Discussion Question: What are some important economic decisions you will be facing within the next 5 weeks? 5 months? One year? Five years?

Slide 29

Diagram illustrating the concept of opportunity cost. It shows the various combinations of goods and/or services an economy can produce when all productive resources are fully employed. Identifying possible alternatives allows an economy to examine how it can best put its limited resources into production. Considering different ways to fully employ its resources allows an economy to analyze the combination of goods/services that lead to maximum output.

Slide 30

50 units of butter will only cost 30 units of guns 120 units of guns will cost 50 units of butter Between pts A & B exists a near equal trade-off, which means a competition for resources

Slide 31

Opportunity Costs: Expressed in terms of trade-offs, or in terms of things given up to get something else The Cost of idle resources: If some resources are not employed, it is difficult for any company, nation, or individual to reach its true potential Economic Growth: Any increase in resources and/or productivity causes the production possibilities frontier to move outward

Slide 32

Build simple models to analyze or describe actual economic situations. Employ Cost-Benefit Analysis: Compare the cost of an action to the benefits received (Ex. ?) Baby Steps: Make decisions by taking small, incremental steps toward the final goal

Slide 33

Studying economics will help us know how the economy works on a daily basis. Helps us understand the Free Enterprise economy where consumers and privately owned businesses, not the government, make a majority of the economic decisions.

Slide 34

Helps us become better decision-makers, both in our personal and professional lives AND at the voting booth!!

Slide 35

Every time a choice is made, something is given up! Rational choice is taking the things with greater value and giving up those with lesser value On an individual level, the choices are not so difficult On the societal level, the choices may not be so easy to make
