Business Cycle – Real GDP Over Time
A diagram illustrating the fluctuations in real GDP over time, including periods of boom, recession, peak, and trough, relative to the long-term trend of economic growth.

trend
Trend: The long-term growth path of the economy's potential output.
gdp
Real GDP: The actual level of output fluctuating above and below the trend line.
peak
Peak: The highest point in a cycle before a downturn begins.
trough
Trough: The lowest point in a cycle, signaling the end of a recession.
boom
Boom: A phase of above-trend growth with falling unemployment and rising inflation.
recession
Recession: A phase of below-trend growth, often with rising unemployment and declining inflation.
The business cycle shows the periodic fluctuations in real GDP around the long-term trend line.
A boom is a period of rapid economic growth above the long-term trend, often leading to inflationary pressure.
A peak marks the highest point of GDP before economic activity begins to slow down.
A recession is characterized by a decline in real GDP, typically for two consecutive quarters, leading to higher unemployment and lower inflation.
The trough is the lowest point of the cycle, from which the economy begins to recover.
The trend line represents the potential output of the economy if all resources were used efficiently over time.
