Overview of Stagflation

  • Definition of Stagflation

    • Coined during the 1970s in the United States
    • A combination of the terms stagnation and inflation

  • Stagnation

    • Refers to an economy that is stagnant, meaning it is not growing

  • Inflation

    • Defined as a general increase in the prices of goods and services

  • Final Definition

    • Stagflation describes an economy that is characterized by both:
    • High unemployment
    • Rising inflation

Illustration of Stagflation Using Aggregate Demand and Supply Model

  • Starting Point: Long-run equilibrium represented by

    • Price level: P
    • Real GDP: y*

  • Cause of Stagflation:

    • Negative shocks, such as rising input costs, lead to a leftward shift in the aggregate supply curve
    • Example: Shift from AS to AS1

  • Effects of the Shift:

    • Movement to a new short-run equilibrium
    • Real GDP falls from y* to y1
    • As output decreases, unemployment rises due to less labor being needed for lower output
    • Price level changes
    • Moves from P to P1

  • Short-Run Equilibrium:

    • Characterized by price level P1 and real GDP y1
    • Illustrates the conditions of stagflation, with ongoing stagnation and inflation

Historical Context and Economic Implications

  • Pre-1970s Understanding:

    • Before the 1970s, stagflation was not a recognized phenomenon in the US economy
    • Economic fluctuations were primarily attributed to changes in aggregate demand:
    • Increasing aggregate demand led to higher inflation and lower unemployment
    • Decreasing aggregate demand led to lower inflation and higher unemployment

  • 1970s Economic Events:

    • Aggregate supply shocks, primarily caused by:
    • Oil embargoes
    • Domestic economic policies
    • Resulted in simultaneous increases in both inflation and unemployment

Conclusion

  • Significance of Stagflation:

    • The term has become a crucial descriptor for economies experiencing recession and is now widely recognized as a concerning economic condition

  • Practical Application:

    • Understanding stagflation is essential for analyzing economic policies and consumer behavior in response to economic conditions.
