2. Inflation Standard 5 Notes Part I

3. Inflation- a sustained rise in the level of prices generally or a sustained decrease in purchasing power. Inflation

4. 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?

5. 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. What causes inflation?

6. Cost-push Inflation

7. 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. What is the impact of inflation?

8. How 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. Inflation

9. Creeping inflation- small rate of inflation over a long period of time • Galloping Inflation- a rapid increase in price level • Hyperinflation- a rapid, uncontrolled rate of inflation in excess of 50% per month • Deflation-a decrease in the in the general price level Types of Inflation

10. Deflation

12. GDP Standard 5

13. Reading Check • GDP= (Gross Domestic Product) • Market value of all final G/S produced within a nation in a given time period

14. Reading Check • Final Good • t-shirt • Intermediate good • fabric used to make a t-shirt • Which (final or intermediate) is not included in the GDP? • Intermediate

15. Reading Check • Nonmarket activities are not included in the GDP because they are services that people don’t charge for. • performing one’s own home repairs • Homemaker’s cooking, cleaning, and childcare • Underground economy- because the activities are illegal, and thus unreported to the government • illegal- drug dealing • plumber who works for cash (not reported on his taxes) • Quality of Life (GDP does not show how G/S are distributed- US highest GDP, but 10%+ of Americans live in poverty)

16. Challenge Question • If you get paid in cash to baby-sit, mow lawns, or do other chores for neighbors, are you part of the underground economy or non market activities? • Underground economy- if you don’t claim the money you made on your taxes

17. Calculating GDP: C+I+G+X=GDP (C) Consumption = household spending on consumer goods and services + (I) Investment = spending by firms and households on new capital such as factories, tools, inventory increases or decreases, and new houses + (G) Government Spending = government spending on public goods and services + (X) Net Exports = foreign trade (exports are added to GDP and imports are subtracted)

19. GDP Growth/Reduction • When GDP is growing • an economy creates more jobs and more business opportunities • When GDP declines • jobs and more business opportunities become less plentiful

21. 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) • (Nominal GDP Growth Rate % - Inflation Rate % = Real GDP Growth Rate %)

24. Marriage? Benefit= can split the mortgage bill with someone else Cost= have to pay for the wedding • Small Wedding • $1,500 • Or $125 a month • Medium Sized Wedding • $10,000 • Or $835 a month • Large Wedding • $20,000 • Or $1,670 a month

25. 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

26. 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

27. 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 http://www.classzone.com/cz/books/econ_cnc/resources/htmls/animated_economics/ec12_anim_macroequilib.html

28. Aggregate Demand Decrease in aggregate demand Contraction phase • Increase in aggregate demand • Expansion phase

29. 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)

30. 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
