InflationStandard 5 Notes Part I
Inflation
Inflation- a sustained rise in the level of prices generally or a sustained decrease in purchasing power.
What causes inflation?
Demand-pull inflation- results when total demand rises faster than the production of goods and services
"more money chasing the same amount of goods.“
What causes inflation? Cost-push inflation- results when
increases in the costs of production push up prices.◦ Inputs like labor, land, capital, and
management◦ Wage-price spiral- a cycle that
begins with increased wages, which lead to higher production costs, which in turn result in higher prices, which result in demands for higher wages.
Cost-push Inflation
What is the impact of inflation?
Decreasing Value of the Dollar◦ people on fixed incomes are hit hard. They do not receive wage increases. ◦ EX: People on social security
Increasing Interest Rates◦ borrowing money becomes more expensive to keep up with the rate of
inflation. Credit card payments rise. Consumers buy less items that require borrowing like houses and cars.
◦ Ex. Fred wants to buy a car valued at $10,000 Fred saved up for a plan where the interest rate is 5% ($188 a month) Inflation caused interest rates to increase to 10% (now $212 a month) Over his 5 yr loan period, Fred will end up paying over $1,425 more for his loan
at the higher rate
Decreasing Real Returns on Savings◦ if the inflation rate is higher than your interest rate in your savings account
or bond, you can lose money that you are trying to save.
InflationHow is it measured?
◦ Consumer Price Index (CPI)- a measure of changes in the prices of goods and services commonly purchased by consumers.
◦ Producer Price Index (PPI)- a measure of change in wholesale prices
◦ Inflation Rate- the rate of change in prices over a set period of time.
Types of InflationCreeping inflation- small rate of inflation
over a long period of timeGalloping Inflation- a rapid increase in price
levelHyperinflation- a rapid, uncontrolled rate of
inflation in excess of 50% per monthDeflation-a decrease in the in the general
price level

GDP
Standard 5
Gross Domestic Product (GDP)
• Market value of all final G/S produced within a nation in a given time period
• To be included, a G/S must be final (intermediate- fabric, final- shirt) and produced within borders
• Calculating GDP:Consumption (C)
+ Investment (I) + Government Spending (G) + Net Exports (Foreign trade, X)
• When GDP is growing– an economy creates more jobs and more business
opportunities
• When GDP declines– jobs and more business opportunities become less plentiful
2 Types:
• Nominal GDP- stated in the price levels for the year in which the GDP was measured
• Real GDP- nominal GDP adjusted inflation (for changes in prices)– An estimate of the GDP if prices were to remain
constant from year to year
What GDP Does Not Measure
• Nonmarket activities (i.e. home childcare or performing one’s own home repairs)
• Underground economy (i.e. illegal- drug dealing and legal- plumber who works for cash)
• Quality of Life (GDP does not show how G/S are distributed- 10%+ of Americans live in poverty)
Just checking…
• If you get paid in cash to baby-sit, mow lawns, or do other chores for neighbors, are you part of the underground economy? Why or why not?
• Yes, if you are required to file taxes and do not report the income to the IRS
• No, if you do report taxable income
How economic value might be assigned to homemaking activities:
• Choose a partner.• Attempt to determine a dollar value for one
adult’s full-time homemaking activities for one year.
• Take notes about the process you use to arrive at that figure.

Business Cycle
• A series of periods of expanding and contracting economic activity• Four Phases:
– Expansion• A period of economic growth (an increase in a nation’s real GDP)
– Peak• The point at which GDP is highest
– Contraction• Sometimes a recession (6 months+) or depression (extended period of high
unemployment and limited business activity)– Trough
• The point at which real GDP and employment stop declining
How economic growth is measured• Real GDP per capita– Real GDP/Total Population– Reflects each person’s share of real GDP– Some people will have more money, others less– Does not measure quality of life
One way to understand business cycles is through demand and supply…
• Aggregate demand- the total amount of G/S that households, businesses, government and foreign purchases will buy at each and every price level
• Aggregate supply- the total amount of G/S that producers will provide at each and every price level

Aggregate Demand• Increase in aggregate
demand• Expansion phase
• Decrease in aggregate demand
• Contraction phase
Why do Business Cycles Occur?• Business decisions
• Aggregate supply increase can cause an economic expansion
• Changes in interest rates• Rise in interest rates= decrease in AD (aggregate demand)• Fall in interest rates= increase in AD
• Consumer expectations• Ways consumers feel about prices, job prospects, businesses activity
cause changes in aggregate demand
• External issues (i.e. Hurricane Katrina, oil embargo of 1973)
Business Cycles in U.S. History
• The Great Depression– Real GDP declined by about a third– Sales in some big businesses
declined by as much as 50 percent– 1 in 4 people were unemployed
• The New Deal– Government agencies created– Many Americans were put back to
work– Some trees in Eagle Creek Park
were planted during this time
