Definition
The business cycle is the natural rise and fall of economic growth that occurs over time. It is characterized by four main phases: expansion, peak, contraction (or recession), and trough. During the cycle, various factors such as output, employment, income, and sales are affected, leading to periods of economic boom and busts.
Phases of the Business Cycle
-
Expansion: This phase is marked by increased economic activity, rising employment, higher consumer spending, and growth in the gross domestic product (GDP). Businesses invest more, and confidence tends to be high.
-
Peak: The peak is the zenith of economic activity where expansion hits its highest point. It is characterized by high output and employment, often accompanied by inflationary pressures.
-
Recession (Contraction): During this phase, there is a significant decline in economic activity. Employment and consumer spending decrease, leading to lower production and investment.
-
Trough: This stage represents the lowest point of the cycle, where economic activity is at its lowest. It precedes the recovery phase.
-
Recovery: The recovery phase signals a turnaround from the trough, as economic activity begins to improve. Employment rates rise, consumer confidence returns, and GDP starts to grow again.
Examples
- The Great Depression (1929-1939): This marked a severe worldwide economic downturn, characterized by significant contraction and a long trough.
- The Dot-Com Bubble (1995-2000): Initially an expansion driven by technology stocks, it peaked and then led to a recession when the bubble burst.
- The Great Recession (2007-2009): Triggered by the subprime mortgage crisis, this period saw a severe contraction in economic activity worldwide.
