Phases of the business cycle
The business cycle moves through expansion, peak, contraction and trough, then recovery, with irregular length and depth.
What it means
- Expansion: rising output, employment, investment and prices.
- Peak: activity at its highest; shortages and inflation may appear.
- Contraction: falling demand, output and employment.
- Trough: lowest point; recovery begins after it.
- Two quarters of falling GDP
Answer: Contraction phase
- Deep, long trough (1930s)
Answer: Great Depression
Related terms
- Stagflation: inflation with stagnant output
- Soft landing: slowdown without recession
Exam tip: Peak and trough are turning points; expansion and contraction are phases.
Leading, coincident and lagging indicators
Leading indicators change before the economy turns, coincident ones with it, and lagging ones after it.
What it means
- Leading: stock prices, new orders, building permits, consumer expectations.
- Coincident: GDP, industrial production, personal income.
- Lagging: unemployment rate, interest rates, inflation.
- Policymakers watch leading indicators to act early.
- Stock prices fall sharply
Answer: Possible slowdown ahead
- Unemployment still rising after GDP recovers
Answer: Normal lag

Theories of business cycles
Different economists blamed different causes: sunspots (Jevons), bank credit (Hawtrey), over-investment (Hayek), innovation (Schumpeter), psychology (Pigou), aggregate demand (Keynes).
What it means
- External causes: sunspots and weather, wars, technology shocks.
- Internal causes: credit, investment, demand, expectations.
- Keynes: investment changes multiplied through income.
- Modern view: a mix of demand and supply shocks.

Try 3 CA Foundation-style questions
Q1. Joseph Schumpeter explained business cycles mainly by
- innovations
- sunspots
- changes in money supply only
- psychology of businessmen only
Show answer
Answer: (1) innovations
Schumpeter's innovation theory: clusters of innovations cause booms; the cycle ends as the innovation spreads and profits fall.
Q2. According to Keynes, business cycles are mainly caused by fluctuations in
- sunspot activity
- population
- aggregate (effective) demand, especially investment
- the gold standard only
Show answer
Answer: (3) aggregate (effective) demand, especially investment
Keynes: changes in aggregate demand, driven largely by investment and the multiplier, cause output and employment to fluctuate.
Q3. The phase in which output, income and employment are falling is
- contraction (recession)
- expansion
- recovery
- peak
Show answer
Answer: (1) contraction (recession)
During contraction, demand falls, firms cut output and jobs, and investment declines.
