Study Notes
An output gap is the difference between the actual level of economic output (GDP) and the potential level of output that an economy could produce at full employment. Example: Economists use output gaps to assess whether an economy is operating above or below its capacity.
- Positive Output Gap — occurs when actual GDP exceeds potential GDP, indicating full utilization of resources and potential inflationary pressures. Example: A surge in consumer spending can push GDP beyond sustainable levels, creating a positive output gap.
- Negative Output Gap — happens when actual GDP is below potential GDP, showing underutilization of resources and economic downturn. Example: During a recession, decreased demand can cause GDP to fall below potential, resulting in a negative output gap.
- Demand-Side Shocks — sudden changes in consumer spending, investment, or government expenditure affecting output gaps. Example: A sudden increase in government spending can create a positive output gap.
- Supply-Side Shocks — disruptions in technology, labor productivity, or resource availability impacting potential output. Example: A technological advancement can increase potential output, affecting the output gap.

- Misunderstanding the role of demand-side and supply-side shocks
Typical Exam Questions
- What is an output gap? An output gap is the difference between actual GDP and potential GDP.
- What is the distinction between actual and potential growth? Actual growth refers to the increase in GDP, while potential growth is the increase in the economy's capacity to produce.
- Demonstrate a positive output gap with an AD/AS diagram. Show actual GDP exceeding potential GDP on the diagram.
What Examiners Usually Test
