Trade (business) cycle explained
The trade (business) cycle describes recurrent fluctuations in real GDP around its long-run trend.
Read the full explanation
Its phases are boom, downturn (recession), slump (trough) and recovery (upswing). In a boom, real GDP grows quickly, unemployment falls and inflationary pressure builds. A downturn follows as growth slows, often triggered by falling demand or a shock; a recession is commonly described as at least two consecutive quarters of negative real GDP growth. At the trough, output is at its lowest before recovery begins, with high unemployment and spare capacity. Recovery brings rising output and employment. The cycle links to output gaps: booms tend to produce positive gaps, downturns and slumps negative gaps. Cycles differ in length, depth and cause, so the pattern is a tendency, not a fixed timetable.
Your focus
- Define the trade (business) cycle and identify its phases in sequence.
- Describe the typical characteristics of each phase using real GDP growth, unemployment and inflation.
- Explain how phases of the cycle relate to positive and negative output gaps.
Trade (business) cycle exam tips
Marking Points
- Defines the trade (business) cycle as fluctuations of real GDP around its long-run trend.
- Names the phases: boom, downturn or recession, slump or trough, and recovery or upswing.
- Describes a boom as rapid growth with falling unemployment and rising inflationary pressure.
- Describes a recession as a period of negative real GDP growth, often taken as at least two consecutive quarters.
- Describes the trough as the lowest point before recovery, with high unemployment and spare capacity.
- Links cycle phases to output gaps: booms to positive gaps and downturns to negative gaps.
Examiner Tips
- 💡Define the cycle in one sentence, then name and sequence the phases before adding detail.
- 💡Use real GDP growth, unemployment and inflation as indicators to distinguish phases in a multiple-choice option.
- 💡Check the wording of options for absolute claims such as always or never, which usually misdescribe the cycle.
Common Mistakes
- Treating the cycle as regular and predictable: its length and depth vary and causes differ; correct by describing it as a tendency rather than a fixed pattern.
- Equating a slowdown with a recession: a recession requires negative real GDP growth, commonly two consecutive quarters; correct by distinguishing slower growth from falling output.
- Assuming the trough means zero output: the trough is the lowest point of the cycle, not an absence of production; correct by describing it as the minimum before recovery.
- Confusing the trade cycle with seasonal variation: seasonal changes recur within a year, while the trade cycle spans years; correct by keeping the timescales distinct.
