FINAL EXAM REVIEW

UNIT I: SUPPLY & DEMAND

Demand-

the desire for a product and the ability to pay for it

Law of Demand-

states that as prices decrease, the quantity demanded increases; and when price increases, the quantity demanded decreases

Price

Properties of Demand Curves

Movement Along– Occurs when prices go up & down

Shift in the Curve– Occurs when there is change in something other

than price

What is Elasticity?

How sensitive you are to a change in price

What is the general rule on elasticity?• The more substitutes there are, the

more elastic you are

Factors that Determine Elasticity

• Are there good substitutes?– Yes = elastic No = inelastic

• What proportion of income does it use?– Large = elastic Small = inelastic

• Is it a necessity or a luxury?– Luxury = elastic Necessity = inelastic

Elastic vs Inelastic Demand Curves

Factors that shift demand curves

Complementary goods– Goods used with another good

Substitute goods• Goods used instead of another good

Why does this happen?

Substitution Effect– As prices increase, people buy other similar goods

Income Effect• As prices increase, you can’t buy as much

Factors that will shift the demand curve left or “in”

People buy less at each price!!1.Decrease in income2.Price of substitute falls3.Price of compliment increases4.Poor product expectations5.Expect price to fall

Shift the demand curve right or “out” are exactly the opposite!

People will BUY MORE at each price!!1.Increase in income2.Price of substitute rises3.Price of compliment decreases4.Good product expectations5.Expect the price to remain the same/increase

Surplus v. shortage

Surplus–Supply is greater than demand

Shortage–Demand is greater than supply

Law of Supply

The supply model is used to try and predict the behavior of suppliers in a given market. It shows the amount a producer is willing to put on the shelf at each given price!!

As price goes up, business will supply more

Properties of Supply Curves

Movement along occurs when there is a change in price

A shift in the curve occurs when there is change in something other than price.

Factors that shift supply curves left or “in”

1. A decrease in producers2. A decrease in technology3. An increase in input cost4. An increase in the price of a related output

Fixed Costs

• Expenses that the owner of a business must incur whether they produce nothing, a little, or a lot.

THEY ARE CONSTANT

Variable Costs

• Business costs that vary as the level of production output changes

CHANGE AT EACH QUANTITY

Total Costs:FC + VC = TC

What is market equilibrium?

What is equilibrium price?

OCCURS WHEN QUANTITY DEMANDED AT A PARTICULAR PRICE = QUANTITY SUPPLIED

AT THAT PRICE

PLACE WHERE THE MARKET IS IN BALANCE; PRICE AT WHICH QUANTITY DEMANDED =

QUANTITY SUPPLIED

UNIT III: LABOR & UNEMPLOYMENT

UNEMPLOYMENT RATE:

The percentage of the labor force that is jobless and actively looking for work

The US Bureau of Labor Statistics surveys 60,000 households each month to determine this number.

Our current unemployment rate:

8.2%Highest unemployment rate during the Great Depression:

25%http://www.youtube.com/watch?v=vuMiwRDGqCU&feature=related

What two qualifications must a person have to considered unemployed? (16+

years old)?

1. NOT WORKING, BUT ARE ABLE TO WORK

2. HAVE LOOKED FOR WORK SOMETIME IN THE PREVIOUS FOUR WEEKS

TYPES OF UNEMPLOYMENT

Frictionally Unemployed-THE TEMPORARY UNEMPLOYMENT OF

WORKERS MOVING FROM ONE JOB TO ANOTHER

Structurally Unemployed-UNEMPLOYMENT THAT EXISTS WHEN THE

AVAILABLEJOBS DO NOT MATCH THE SKILLS OF AVAILABLE WORKERS

Cyclical Unemployment-• UNEMPLOYMENT CAUSED BY THE

PART OF THE BUSINESS CYCLE WITH DECREASED ECONOMIC ACTIVITY

Seasonal Unemployment-• UNEMPLOYMENT LINKED TO

SEASONAL WORK

UNDEREMPLOYMENT:People employed part-time who want to work full-

time, or those who work at a job below their skill level

FULL EMPLOYMENT:No unemployment due to decreased economic activity

http://www.pbs.org/newshour/video/module.html?mod=0&pkg=2072009&seg=5

LABOR UNIONAn organization of workers who collectively seek to improve wages, working conditions, benefits, job security, and other work-related matters; Labor unions began in the late 1800’s

due to working conditions in factories.

WAGES• payments workers receive in return for work

Minimum wage•the lowest amount established by law, an employer may pay a worker for one hour of work

The price for labor is dictated by the laws of supply and demand.

Equilibrium wage:the wage at which the quantity of workers demanded equals the quantity of workers

supplied

Poverty:having little or no money,

goods, or means of support

Living wage:minimum income necessary for a worker to meet basic needs

to live in a specific area

U3: Official Unemployment Rate

People without any kind of job who have been actively looking for work within the last month

7 – 8%

FORMULA: Unemployment Rate = number unemployed U.S. labor force

 *To be included in the labor force you must be considered

employed or unemployed!*

•Prevent people from doing what they want

•Lower standard of living

COMMAND• A system where society’s leaders, usually central

government make all economic decisions; called a CENTRALLY PLANNED ECONOMY

UNIT VI: THE SEVEN BILLION

Human Development Index (HDI) – combination of a nation’s real GDP per capita, life expectancy, adult literacy rate and student enrollment figures

GDP per Capita-A nation’s overall GDP divided by population

Ex. GDP of the US is over $40,000 (among the highest)GDP of Tanzania (E. Africa) is $700 (among the

lowest)

What is GDP?

The market value of all final goods & services produced within a nation’s borders in a given time period (often used annually)

Measures 2 things at once:1.Total income of everyone in the economy2.Total expenditure on the economy’s output

of goods

3. What is not counted?

a. Intermediate productsb. Buying used goods c. Not produced in U.S.d. Off-market transactionse. Black Market

IMF (International Monetary Fund)The International Monetary Fund (IMF) is

an organization of 187 countries, working for global monetary cooperation, secure financial stability, facilitate international

trade, promote high employment and sustainable economic growth, and reduce poverty around the world; countries pay into the IMF and can

borrow money at low rates; IMF works for fair loans & loan terms for LDC’s.

UN Development ProgramUNDP is the United Nations' global development

network, an organization advocating for change and connecting countries to

knowledge, experience and resources to help people build a better life. They are on the

ground in 177 countries, working with them on their own solutions to global and national development challenges. When faced with issues of globalization, countries turn to the

UNDP to bring in experts to work with governments on problem-solving.

UNIT VII: FISCAL POLICY & BANKING

INFLATION

SUSTAINED RISE IN GENERAL PRICE LEVEL, OR THE

SUSTAINED FALL IN THE PURCHASING POWER OF

MONEY

What is a business cycle?A SERIES OF PERIODS OF EXPANDING AND CONTRACTING ECONOMIC ACTIVITY

How is the business cycle measured?AN INCREASE OR DECREASE IN REAL GDP

A. EXPANSION PHASE-REAL GDP GROWS RAPIDLY

B. THE PEAK-GDP REACHES HIGHEST

POINTC. CONTRACTION

PHASE-REAL GDP DECLINES

D. THE TROUGH-MARKS THE END

OF CONTRACTION

The expansion stage of the business cycle is a period of

ECONOMIC GROWTH, or an increase in the GDP. JOBS are usually easy to find so UNEMPLOYMENT goes down.

More RESOURCES are needed to keep up with spending DEMAND. The PEAK is the point at which GDP is the highest. As prices RISE and RESOURCES tighten, businesses become less PRODUCTIVE.

After the peak begins the CONTRACTION phase. What happens during this phase?

THIS IS THE POINT OF THE BUSINESS CYCLE WHERE REAL GDP FALLS AND PRODUCERS CUT BACK

The final phase is TROUGH. This is the point where both REAL GDP and EMPLOYMENT stop declining. The cycle is done when:IT HAS GONE THROUGH ALL FOUR PHASES

DEMAND-SIDE ECONOMICS:

FISCAL POLICY TO STIMULATE AGGREGATE DEMAND– KEYNESIAN

ECONOMICS

What was Keynes first

revolutionary idea?

He defined AGGREGATE DEMAND as the sum of all

demand in the economy

Laffer Curve

Illustrates how tax cuts affect tax revenues and economic growth.Tax revenues increase as tax rates increase to a certain point.

After that point, higher taxes actually lead to decrease tax revenue.WHY?

Too high of taxes could actually discourage people from working, investing, and

spending.

AUTOMATIC STABILIZERS:Features of fiscal policy that work automatically to stabilize the economy

PUBLIC TRANSFER PAYMENTSUnemployment compensation, food stamps, welfare, etc.; when people receive these benefits, they gain income to spend so that recession is less severe on the individual/family. In a weak economy, more people qualify for these benefits; in a strong economy, less qualify

DISCRETIONARY FISCAL POLICY:

Actions taken by the government by choice to correct economic instability; Congress must enact legislation in order for these policies to be implemented. (Similar to discretionary spending)

EXPANSIONARY FISCAL POLICY:Plan to increase aggregate demand and stimulate a weak economy

CONTRACTIONARY FISCAL POLICY:

Plan to reduce aggregate demand and slow down an inflationary (too-rapidly expanding) economy

SUPPLY-SIDE

Cut corporate taxes

Lower production costs

More $ for hiring workers

More supply is made

But, more people have $ to spend

and demand goes up

Businesses make $ due to increased

demand

What is a balanced budget?WHEN A GOVERNMENT SPENDS WHAT THEY TAKE IN IN TAXES

What is deficit spending?WHEN A GOVERNMENT SPENDS MORE THAN IT COLLECTS IN A SPECIFIC BUDGET YEAR

What is national debt?THE DEFICIT SPENDING THAT ACCUMULATES FROM YEAR TO YEAR

1. Portable2. Divisible3. Durable4. Uniform

Physical Characteristics of Money

How does the Federal reserve system

operate?• It’s main function is to control the

money supply through monetary policy

• The power of the Fed has grown to the point where its decisions have enormous impact on the economy.

The Reserve Requirement: The Fed’s most powerful

tool• A fraction of the bank’s deposits that must be kept in reserve by the bank to control the amount the bank can lend

• Usually vary between 3% & 14% of total deposits.

• CONTROLLING THE MONEY SUPPLY:Increase supply = LOWERS RRDecrease supply = RAISES RR

The Discount Rate: The Fed acts as a lender to banks

• Interest the Fed charges when it lends money to banks

• When the prime rate or discount rate changes, all INTEREST rates will change.

• CONTROLLING THE MONEY SUPPLY:Increase supply = LOWERS DRDecrease supply = RAISES DR

The Federal Open Market Operations: The Fed’s most important & most frequently

used tool• to adjust the money supply• The Fed is the nation’s owner of

SECURITIES (bonds, Treasury bills, Treasury notes)

• CONTROLLING THE MONEY SUPPLY:Increase supply = BUYS securitiesDecrease supply = SELLS securities

The Federal reserve constantly monitors

• the money supply• It will increase or decrease the money

supply by increasing or decreasing interest rates.

• The ECONOMY reacts to decisions by the FEDERAL RESERVE
