ECONOMICS:The study of the allocation of

our scarce resources to satisfy our unlimited wants for goods

and services.

Page 3: ECONOMICS What does it mean to me? The Ten Powerful Ideas of EconomicsThe Ten Powerful Ideas of Economics.

Economics is:

*A social science concerned with how resources are used to satisfy wants.

*A study of how people and countries use their resources to produce, distribute, and consume goods and services.

*An examination of behavior related to how goods and services are acquired.

*A study of how people decide who will get the goods and services.

Capital Resources: includes any good used to create a final good or

service.

CAPITAL RESOURCESCAPITAL RESOURCES are further divided into:

CAPITAL GOODS

Goods used in the production process that can be reused

for another product. (computers, trucks,

machines.)

INTERMEDIATE GOODS

Goods that are used up in the

production process. (paper, oil, ink,.)

There are 10 powerful ideas that serve as the foundation

of economics.

If you develop a good understanding of them and master the problem-solving skills inherent in them, they will serve you for the rest of

your life.

Page 15: ECONOMICS What does it mean to me? The Ten Powerful Ideas of EconomicsThe Ten Powerful Ideas of Economics.

NUMBER 1:

WANTS AND DESIRES

How do we satisfy our unlimited wants and desires

in a world of limited resources?

Page 16: ECONOMICS What does it mean to me? The Ten Powerful Ideas of EconomicsThe Ten Powerful Ideas of Economics.

“Goods” and “services” are those things that we value or desire.

GOODS tend to be TANGIBLETANGIBLE things--objects that can be seen, held, tasted, heard, or smelled.

INTANGIBLE GOODSINTANGIBLE GOODS are things we cannot reach out and touch, such as friendship, knowledge, and

fairness. SERVICES are intangible.

Page 17: ECONOMICS What does it mean to me? The Ten Powerful Ideas of EconomicsThe Ten Powerful Ideas of Economics.

In contrast to goods, BADS are items that people do not desire or want---garbage, pollution, weeds, and crime.

The elimination of a bad becomes a good.

In economics, we assume that more goods lead to greater

satisfaction, or UTILITY, and that bads lead to dissatisfaction

or DISUTILITY.

Page 18: ECONOMICS What does it mean to me? The Ten Powerful Ideas of EconomicsThe Ten Powerful Ideas of Economics.

NUMBER 2:

SCARCITY

We all face scarcity because it is not possible for an individual to have all

the goods and services that he or she desires.

However, because we all have differing wants and desires, scarcity

affects individuals differently.

Page 19: ECONOMICS What does it mean to me? The Ten Powerful Ideas of EconomicsThe Ten Powerful Ideas of Economics.

The essential question in Economics is:

ScarcityScarcity

For instance, antiques are valued For instance, antiques are valued for their scarcity. . .for their scarcity. . .

the same as poverty. (eg. Goods can be scarce in United States AND Somalia. However, scarcityisn’t going away; poverty might.)

the same as shortage. (eg. Whether you have a shortage or not depends upon how you handle the rationing problem made necessary by scarcity)

Scarcity is NOT:

Page 22: ECONOMICS What does it mean to me? The Ten Powerful Ideas of EconomicsThe Ten Powerful Ideas of Economics.

NUMBER 3: CHOICESWe may all want a home, two cars,

gourmet food, all with a pristine environment with no pollution. If we had unlimited resources to produce

all of the goods and services everyone wanted, we would not have to choose

among these decisions.

If we did not have to make meaningful economic choices, the study of

economics would not be necessary.

Page 23: ECONOMICS What does it mean to me? The Ten Powerful Ideas of EconomicsThe Ten Powerful Ideas of Economics.

Scarcity forces us to choose and choices

are costly because we always give up other

opportunities.

Economists call this OPPORTUNITY

COST.

Opportunity Cost:Opportunity Cost:

Page 25: ECONOMICS What does it mean to me? The Ten Powerful Ideas of EconomicsThe Ten Powerful Ideas of Economics.

Everyone must give up something to get more of other things, called

trade-offs.

Page 26: ECONOMICS What does it mean to me? The Ten Powerful Ideas of EconomicsThe Ten Powerful Ideas of Economics.

Some economists argue that we are worse off because of the FDA (Food

and Drug Administration).

What are the “costs” of having a government administrative agency control the food and

drugs a society can consume?

Page 27: ECONOMICS What does it mean to me? The Ten Powerful Ideas of EconomicsThe Ten Powerful Ideas of Economics.

TINSTAAFL

(There is no such thing as a free lunch)

This statement clarifies the relationship between scarcity and opportunity cost. If the cafeteria is offering “free” lunches, is it really free from society’s perspective?

Could the resources used to create the free lunch have been used to create something else of value?

Technically, this is called a “subsidized”

lunch.

Page 28: ECONOMICS What does it mean to me? The Ten Powerful Ideas of EconomicsThe Ten Powerful Ideas of Economics.

Prices and Costs are NOT the same Prices and Costs are NOT the same thing.thing.

PRICES reflects the monetary value of a good or service, which is an objective fact.

COSTS are personal and subjective.

For example, would a $60,000 Lexus cost more to a poorer person than a richer one?

They both give up the same amount of money, however, the costs are different for

each person.

In market settings, goods have positive prices

Too often the long-termlong-term consequences of a choice is ignored.

“….must trace not merely the immediate results but the results in the long run, not merely the primary consequences but the secondary consequences, and not merely the effects on some special group but the effects on everyone.”

--Henry Hazlitt

Especially in politics there is a tendency to stress the short term

benefits while completely ignoring the longer-term

consequences. . . . we hear an endless pleading for proposals to help specific industries, regions, or groups without consideration

given to their impact on the broader community, including

taxpayers and consumers.

--Common Sense Economics

Page 31: ECONOMICS What does it mean to me? The Ten Powerful Ideas of EconomicsThe Ten Powerful Ideas of Economics.

Consider the rent controls imposed on apartments. Cities like Berkeley and Santa Monica, California, as well as New York City have adopted such controls, usually in response to claims that rent controls will keep rents from rising and make housing more affordable for the poor.

True, in the short run…..but what about the long-run consequences:

1) Market for apartments will decline

*existing apartments will not go to those who need them

*expensive for someone to give up a rent controlled apartment

*hard to find place closer to work because others are holding onto theirs

2) Reduce investment in new housing

*no incentive to build new apartments for the future.

NUMBER 4:

THINKING MARGINALLY

Choices are not all or nothing.

Most choices are of the “little more” or “little less”

variety.Most of us do not dine in the nude so we can afford food.--Common Sense Economics

Page 33: ECONOMICS What does it mean to me? The Ten Powerful Ideas of EconomicsThe Ten Powerful Ideas of Economics.

Economists call this “marginal thinking” because the focus is on the

additional, or marginal, choices.

People will alter their behaviors if they expect the marginal benefits from doing so will outweigh the

expected marginal costs they will bear.

This is called theThis is called the

RULE OF RATIONAL CHOICE.

Page 34: ECONOMICS What does it mean to me? The Ten Powerful Ideas of EconomicsThe Ten Powerful Ideas of Economics.

NUMBER 5: INCENTIVES CREATE

RATIONAL BEHAVIOR

Much of human behavior can be explained and predicted as a response

to incentives.

Rational behavior exists as people respond to incentives--both positive

and negative--in the relative cost-benefit structure.

Page 35: ECONOMICS What does it mean to me? The Ten Powerful Ideas of EconomicsThe Ten Powerful Ideas of Economics.

INCENTIVES are important in communist societies as well.

In the former Soviet Union, employees in a glass plant were rewarded by the number of tons of sheet

glass they produced.

This led to factories producing sheet glass so thick, one could barely see through it.

So they changed the strategy and employees were rewarded by the number of square meters they could

produce.

This led to production of glass so thin that it broke easily.

**Taken from “Common Sense Economics” 2005

Page 36: ECONOMICS What does it mean to me? The Ten Powerful Ideas of EconomicsThe Ten Powerful Ideas of Economics.

Incentives can be either positive or negative.

POSITIVE incentives will either increase benefits or reduce costs.

NEGATIVE incentives will either decrease benefits or increase costs.

Would a tax on cigarettes be a negative or positive incentive?

Page 37: ECONOMICS What does it mean to me? The Ten Powerful Ideas of EconomicsThe Ten Powerful Ideas of Economics.

NUMBER 6:

SPECIALIZATION AND TRADE

People tend to dedicate their resources to one lifetime activity, whether it be teaching school,

child-rearing, or cooking food. Why is this?

The answer is simple: OPPORTUNITY COST.

By concentrating their energies into a single, best- suited activity, individuals

incur lower opportunity costs. In this way, they make better use of their limited

resources.

Page 38: ECONOMICS What does it mean to me? The Ten Powerful Ideas of EconomicsThe Ten Powerful Ideas of Economics.

If a country, region, firm, or person can produce a good or

service for a lower cost, economists would say they have a COMPARATIVE ADVANTAGE.

The advantages of specialization include greater skill, lower costs,

greater efficiency, higher production, and increased wealth.

Page 39: ECONOMICS What does it mean to me? The Ten Powerful Ideas of EconomicsThe Ten Powerful Ideas of Economics.

NUMBER 7:MARKETS AND THE PRICE SYSTEM

How do we determine who gets

what?

The market system allows communication between consumers and

producers regarding the allocation of scarce resources. This is done through PRICES.

Page 40: ECONOMICS What does it mean to me? The Ten Powerful Ideas of EconomicsThe Ten Powerful Ideas of Economics.

Government policy sometimes interferes with the market

system.

Consider how minimum-wage legislation censors effective communication from

teenagers to employers.

While it is true that minimum wage protects teenagers from being paid extremely low wages for unskilled

labor, the increase in minimum wage has two effects on teenage

employment:

There are seven reasons to justify

government involvement into

the economic decision-making

process:

NUMBER 8:GOVERNMENT POLICIES

Governments are institutions devised by

humans to serve the collective group or will.

Page 43: ECONOMICS What does it mean to me? The Ten Powerful Ideas of EconomicsThe Ten Powerful Ideas of Economics.

•government provides legal framework

•some goods and services are inherently “public”

•lack of competition has led markets to operate inefficiently

•government can help participants in market activity make better decisions

•the existence of externalities--like pollution--can cause inappropriate market signals

•income distribution as determined by the market may be considered unfair or inappropriate

•overall level of output may be viewed as inappropriate in the market.

NUMBER 9:

ECONOMIC GROWTH

Economic growth enhances the potential amount of individual consumption---the greater the economic growth, the more

goods we and our descendants will have to consume in the future.

Page 45: ECONOMICS What does it mean to me? The Ten Powerful Ideas of EconomicsThe Ten Powerful Ideas of Economics.

Americans produce and earn approximately 30 times as much per person today as in 1750.

Why are Americans so much more productive than 250 years ago?

1) Scientific knowledge and technological abilities

2) Complex machines and factories, better roads, extensive systems of communication

3) Families in 1750 directly produced most of the items they consumed; today we purchase them from others

--Common Sense Economics

Page 46: ECONOMICS What does it mean to me? The Ten Powerful Ideas of EconomicsThe Ten Powerful Ideas of Economics.

Other sources of economic growth:

1) Investments in people (skills) and machines (assets)

2) Improvements in technology (brain power, less cost)

3) Improvements in Economic Organization

*human activities

*entrepreneurship

*open markets promote free exchange of ideas

*competition

PRICE STABILITY

NUMBER 10:

When overall prices increase in an economy, it is called INFLATION.

When overall prices decrease, it is called

DEFLATION.

When either of these conditions exist, the

PURCHASING POWER of money is changing.

Page 48: ECONOMICS What does it mean to me? The Ten Powerful Ideas of EconomicsThe Ten Powerful Ideas of Economics.

Inflation will cause the purchasing power of money to decrease.

It can raise one nation’s prices relative to prices in other countries , which will lead to difficulties in financing foreign goods.

In extreme situations, it can erode the faith the people have in the currency resulting in the refusal to accept paper money as a form of payment.

Page 49: ECONOMICS What does it mean to me? The Ten Powerful Ideas of EconomicsThe Ten Powerful Ideas of Economics.

In a deflationary period, the purchasing power of an

individual will rise, however, businesses may be forced to lay off workers in an effort to

reduce costs to offset the lower prices of the product.
