CHAPTER 2The Economizing Problem

Decision on factors of productionProduction Possibilities Curve

Circular Flow

Thinking about different cultures

• In U.S. – emphasize our position in life.• Is this at expense of environment, education,

greater good? Where? • Majority of U.S. concern for others? Examples.• Does this mean U.S. way the only way?• Tolerance Today…. Is this viable?• Can it help our economy? How? Where?

Economic Wants (anything that can be purchased in the system.)

Break Economic Wants down –• Basic• SocialBASIC: (Food, Clothing, Shelter)SOCIAL: Microwaves, Refrigerator, High Speed

Internet, Air Conditioning, Ipads,

Social Examples U.S. Households

90% have microwave ovens88% have television in living room87% subscribe to cable or satellite TV77% own personal computer72% have flat screen TV68% have broadband Internet service68% have television in their bedrooms.

Factors of Production

Every economy works with these factors. Some have moreresources, more capital, or more land, etc. Some economies do notencourage entrepreneurship.

LAND

CAPITAL

ENTREPRENEURSHIP

PROPERTY RESOURCES

LAND

ECONOMIC RESOURCES

Land- all the bounties of nature- land, minerals, water. What gives land value?

Labor

Human ResourcesQuality vs Quantity

Watch for capital intensive andLabor Intensive

Human’s ability to produce goods and services. Equal opportunity for all--- everyone gets an education.

Capital

In the factors of production Capital is machinery, tools used to make other tools, BUT there are other types of capital

**************physical (good used to produce another good… machinery- tools to produce tractors, computers, roofing machines….*this is why U.S. has a high standard of living (technology, industrial development). Level of consumption depends on R & D to come up with new resources when ones used are getting near depletion.financial- money as such produces nothing. Money only considered as medium of exchange.. Has to be put to use in investment to see growth.human- our mind….can put under physical also because this is a tool…. (for some people)

What is an entrepreneur?

French term “one who begins.”Person who takes the 3 factors.. Puts them

together…. (success and failure)Example- Robert Fulton/steamboat… went

bankrupt 3 times before he convinced people that a boat could be powered by steam.

Thinking Hat Time

• Name some Entrepreneurs today?

Economic Models

Economic model gives incites as to how something works… only a model… cannot be totally accurate.

Production Possibility Curve= modelAssumptions:• maximum amount of any two goods that

can be produced from a fixed amount of resources.

• specific time period• fixed resources and fixed technology

Law of Increasing Opportunity CostsThe amount of other products that must beforgone or sacrificed to obtain 1 unit of a specific

product is called the opportunity cost of that good.

Economic resources arenot completely adapt-able to other uses. Crude Oil is not adaptable to

making bread.

Research and Development R&D

1 – Increase in resource supplies2 - New Resources 3 – Better resource quality 4 – Technological

advances

Where does the impetus of this R & D come from? More from private or public?

Building a Concept• What two things can you do with your

money?• If you put into savings, what happens then?• Can this money be loaned out to businesses?• What will businesses do hopefully?• What is capital?• How can capital be created?• Is consumption important in an economy?• Is capital important in an economy?• OK… Time to ponder!!!

Time to Think… put your “thinking hat on.”

If we do not utilize our resources…what happens?

unemploymentlower standard of living

Where would we be on our PPC?*******Mental exercise….capital goods vs

consumer goods.

• Bottom Line

At some point societies (and individuals) have to abstain from consumption in order to have greater ability to consume in the future.. (does Congress have a social responsibility to reduce deficit?)

We (consumers) determine what goes into consumption/savings…

Resources are limited…. Need to save so that capital can be acquired… (industrial development) But… need to consume also. Especially now.

So, is this what Greece, Spain, Portugal need to learn? What about the U.S.?

Is there a balance? (Enter monetary and fiscal policy decisions)… high interest rates (save incentive) pulls money out of economy and places into investments – should lower inflation…

But, too much saving lowers goods available and increased demand can drive prices up, production down.

Continued OverviewGovernment steps inMarket mechanism (market prices and sales to signal

desire outputs - - or resource allocations.) (prices drive resources!!!)

Government intervention/ command economiesMarket failure (imperfection in market prevents

optimal outcomes) (housing bubble)Government fails- (is this possible?)

forced pollution clean-up- over taxation- mandates that are ineffectual or expensive- economic pie shrinks because businesses cannot adjust.

Or government spends on wrong things…doesn’t help the economic pie, just makes it fatter! Stimulus pkg, Auto bailout? Subsidies to pet political projects?
