    Diagram & Curves
    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.

    Example Exam Question
    Using a diagram, explain the phases of the business cycle and how they affect unemployment and inflation.
