Business Cycles vs. Business Fluctuations
• Business Cycles: regular increases and decreases in real GDP
• Business Fluctuations: irregular increases and decreases in real GDP
They both can interrupt economic growth
![Page 4: Economic Instability](https://reader035.fdocuments.net/reader035/viewer/2022062410/56815ebe550346895dcd438c/html5/thumbnails/4.jpg)
First phase is recession, a period during which real GDP
(GDP measured in constant prices) declines for at least 2
quarters in a row or 6 consecutive months.
![Page 5: Economic Instability](https://reader035.fdocuments.net/reader035/viewer/2022062410/56815ebe550346895dcd438c/html5/thumbnails/5.jpg)
The recession begins when the economy reaches a peak,
the point where real GDP stops going up.
![Page 6: Economic Instability](https://reader035.fdocuments.net/reader035/viewer/2022062410/56815ebe550346895dcd438c/html5/thumbnails/6.jpg)
The recession ends when the economy reaches a trough,
the turnaround point where real GDP stops going down.

As soon as the declining real GDP
bottoms out, the economy moves into the second
phase, expansion – a period of recovery
until the economy reaches a new peak.

When it does, the current business cycle ends and a new one begins.

Trend line: growth path the economy
would follow if it were not interrupted by
alternating periods of recession and recovery

Causes of Changes in the Business Cycle1. Changes in investment spending: When the
economy is expanding, businesses expect future sales to be high, so they invest heavily in capital goods.
2. Innovation and Imitation: Come up with a new product or new way of doing things; copying what other companies may be doing
3. Monetary Policy Decisions: Change of interest rates causing incentives to invest or not
4. External Shocks: oil prices, wars, international conflict, natural disasters

What Happens if a recession becomes very severe?
Depression: a state of the economy with large numbers of people out of work, acute shortages, and excess capacity in manufacturing plants.
![Page 12: Economic Instability](https://reader035.fdocuments.net/reader035/viewer/2022062410/56815ebe550346895dcd438c/html5/thumbnails/12.jpg)
The Great DepressionCauses
• Unequal distribution of income
• Easy Credit• Global economic
conditions
Effects• GDP fell almost 50 percent• Unemployment rose nearly
800 percent• Average manufacturing
wage fell from 55 cents an hour to 5 cents an hour
• Banks failed• Money supply contracted

What’s the difference between inflation and deflation?
• Inflation: increase in the general level of prices of goods and services
• Deflation: decrease in the general level of prices for goods and services
![Page 14: Economic Instability](https://reader035.fdocuments.net/reader035/viewer/2022062410/56815ebe550346895dcd438c/html5/thumbnails/14.jpg)
Market Basket: commonly purchased goods and services
Total of approx. 354 determined
items
![Page 15: Economic Instability](https://reader035.fdocuments.net/reader035/viewer/2022062410/56815ebe550346895dcd438c/html5/thumbnails/15.jpg)
Constructing the Consumer Price Index• Consumer Price Index (CPI): series used to
measure prices changes for a representative sample of frequently used consumer items
1. Select a Market Basket2. Find the average price of each item in the
market basket. Then add up the total for the basket.
3. Have a base year: a year that serves as a comparison for all other years
4. Convert the dollar cost of a market basket to an index value so that it is easier to interpret.

Types of Inflation
• Creeping Inflation: 1-3% inflation per year; not much of a problem
• Hyperinflation: 500% and above inflation per year; very very rare
• Stagflation: period of slow economic growth coupled with inflation
![Page 18: Economic Instability](https://reader035.fdocuments.net/reader035/viewer/2022062410/56815ebe550346895dcd438c/html5/thumbnails/18.jpg)
Causes of InflationCauses of inflation include strong demand,
rising costs, and wage-price spirals, along with a growing supply of money.
• Demand-pull inflation: prices rise because all sectors try to buy more goods and services than the economy can produce; cause shortages, which drive up prices
• Cost-push inflation: rising costs drive up prices of products
![Page 19: Economic Instability](https://reader035.fdocuments.net/reader035/viewer/2022062410/56815ebe550346895dcd438c/html5/thumbnails/19.jpg)
Consequences of InflationInflation can reduce purchasing power, distort
spending, and affect the distribution of income.• Reduce Purchasing Power: dollar buys less as
prices rise• Distort Spending Patterns: • Encourage Speculation: Spend money on
luxury items if the prices are expected to increase
• Distorted Distribution of Income:

UNEMPLOYMENT
![Page 21: Economic Instability](https://reader035.fdocuments.net/reader035/viewer/2022062410/56815ebe550346895dcd438c/html5/thumbnails/21.jpg)

Measuring Unemployment
• Civilian Labor Force: sum of all people age 16 and above who are either employed or actively seeking employment
• Who is classified as unemployed?– People available to work who made a specific
effort to find a job during the past month AND worked less than 1 hour for pay in a week
– Work 15 hours or less in a week in a family business for no pay

Limitations of the Unemployment Rate
1. Doesn’t measure people too frustrated or discouraged to look for work
2. People are considered employed even if they only have part-time jobs

Sources of Unemployment1. Frictional: workers are between jobs; short-term
condition2. Structural: fundamental change in the economy;
more serious type of unemployment, also includes Technological: workers are replaced by machines or automated systems
3. Cyclical: related to changes in the business cycle, also includes Seasonal: annual changes in the weather or other conditions that reduce the demand for jobs
