Business Cycle – Real GDP Over Time

Macroeconomics

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.

Diagram
Business Cycle – Real GDP Over Time
Curves and Elements

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.

Key Explanations
1

The business cycle shows the periodic fluctuations in real GDP around the long-term trend line.

2

A boom is a period of rapid economic growth above the long-term trend, often leading to inflationary pressure.

3

A peak marks the highest point of GDP before economic activity begins to slow down.

4

A recession is characterized by a decline in real GDP, typically for two consecutive quarters, leading to higher unemployment and lower inflation.

5

The trough is the lowest point of the cycle, from which the economy begins to recover.

6

The trend line represents the potential output of the economy if all resources were used efficiently over time.
