Chapter 8 “The Business Cycle”
Overview Our economy has experienced a pattern of uneven growth throughout our history. Some periods are marked by rapid growth while during others the economy declines.
Phases of the Business Cycle 1. Peak – temporary period of full employment and near capacity output. 2. Trough – bottom of a recessionary period. 3. Recession – decline from peak to trough. 4. Recovery – expansion from trough to peak.
Causes of fluctuation 1. Irregular innovation or random events causes changes in business cycle. 2. Aggregate spending is the key.
Non-cyclical fluctuations Seasonal variations are not the business cycle. (more sales around Christmas, etc.) Secular Trends- long term movements of the economy. (cover periods of years.)
Durable and Nondurable goods Durable good and construction industries feel the most impact of the business cycle. These purchases can be postponed. Firms in these industries have monopoly power. They can reduce output when sales go down instead of lowering their price.
Types of Unemployment 1. Frictional – short term, less than 6 weeks. People in between jobs. Somewhat desirable, indicates mobility in the economy.
Types of Unemployment 2. Structural – caused by changes in the structure of the demand for labor. Occurs when jobs become obsolete or geographic need for jobs changes.
Types of Unemployment 3. Cyclical – caused by the recession phase of the business cycle. People who are laid off as we enter a recession.
Full Employment Does not mean zero unemployment. Occurs when cyclical is zero and structural and frictional reach levels that are seen as unavoidable.
Labor Force All persons between ages 16-65, not institutionalized, who are actively looking for a job. Unemployment rate =percentage of labor force that is unemployed.
How is this % calculated A random telephone survey of households is taken. Part time workers count as full time. Discouraged workers are not counted as unemployed.
Unemployment Rate This rate is inaccurate because of the manner in which it is calculated. People lie to the telephone survey takers. The survey is biased against people without phones.
Inflation 1.Rise in the general level of prices. 2. Rising price of one good does not constitute inflation.
Cost of Unemployment = lost output 1. GDP Gap – amount by which actual GDP falls below potential GDP. 2. Okun’s Law – for every 1% unemployment exceeds full (4.5%) there is a corresponding 2.5% GDP gap. 1 : 2.5
Unequal Burden of Unemployment 1. Occupation 2. Age 3. Race 4. Gender
Types of Inflation 1. Demand Pull Inflation – a rise in prices caused by excess demand. 2. Cost Push Inflation – as production costs increase, they are passed on to consumers in the form of higher prices.
Who is hurt by inflation? 1. Fixed Income receivers 2. Savers 3. Creditors
Who is helped by inflation? 1. Flexible income receivers 2. Borrowers/debtors
Hyperinflation and Breakdown 1. extremely rapid inflation, devastating to an economy. A. Post WW1 Germany B. Argentina, Bolivia, Brazil, C. Yugoslavia
Hyperinflation A 500,000,000,000 (500 billion) Yugoslav dinar banknote circa 1993, the largest nominal value ever officially printed in Yugoslavia, the final result of hyperinflation. Yugoslav dinarbanknotenominal valueYugoslavia
