What is a Business Cycle?

• Alternating periods of expansion and contraction.
• Measured through GDP, income, output and employment.
• Consists of four phases.

Name the four phases of a Business Cycle.

• Peak
• Contraction
• Trough
• Mnemonic: EPCT

What are the characteristics of the Expansion phase?

• Employment increases.
• Investment rises.
• Income increases.
• Economy moves towards full capacity.

What happens during the Peak phase?

• Highest level of economic activity.

• Growth starts slowing down.

How does an economy move from Contraction to Trough?

• Demand falls.
• Firms reduce production.
• Unemployment increases.
• Investment declines.
• Economy reaches the lowest point called the Trough.

Differentiate between Leading, Coincident and Lagging Indicators.

• Leading Indicators predict future economic activity.
• Coincident Indicators move with the economy.

Match the following indicators.

• New manufacturing orders and stock prices → Leading Indicators
• GDP, Personal Income and Industrial Production → Coincident Indicators
• Unemployment rate and Prime Lending Rate → Lagging Indicators

true or False: Business Cycles occur at fixed time intervals.

• False.
• Business cycles are recurring but not regular.
• Their duration and intensity differ every time.

• Hawtrey → Purely Monetary Theory
• Schumpeter → Innovation Theory
• Nicholas Kaldor → Cobweb Theory
• Hayek → Over-investment Theory

How does Hawtrey's Monetary Theory explain a recession?

• Interest rates rise.
• Businesses reduce production.
• Prices fall.
• Economy enters recession.

What is the main idea of the Cobweb Theory?

• Common in agriculture.
• Production decisions depend on previous prices.
• Time lag creates repeated price fluctuations.

State three Internal and three External causes of Business Cycles.

Internal Causes:
• Investment fluctuations.
• Aggregate Demand changes.
• Monetary policy changes.

External Causes:
• Wars.
• Technological changes.
• Natural factors.

True or False: Business Cycles affect every sector equally.

• False.
• Capital goods industries are affected the most.
• Essential goods industries are affected less.

Why are Capital Goods and Consumer Durables more affected by Business Cycles?

• Purchases can be postponed.
• Demand falls sharply during recession.
• Essential goods continue to be purchased

How should a business respond during Expansion and Contraction?

Expansion:
• Expand production.
• Invest in new projects.
• Build inventory.

• Reduce costs.

• Microeconomics studies individual consumers and firms.
• Macroeconomics studies the economy as a whole.
• Micro focuses on individual markets.
