The situation where the equilibrium level of real GDP falls short of potential GDP is known as _________.
Recessionary gap
Understanding the Recessionary Gap in Macroeconomics
The question asks about the economic situation where the equilibrium level of real Gross Domestic Product (GDP) is less than the potential GDP. This is a core concept in macroeconomics related to the output gap.
What is Potential GDP?
Potential GDP represents the maximum level of output an economy can sustain over a period without causing accelerating inflation. It's based on using resources like labor, capital, and technology at their natural or full employment levels.
What is Equilibrium Real GDP?
Equilibrium real GDP is the actual level of output produced in the economy at a given time, determined by the intersection of aggregate demand and aggregate supply.
Identifying the Economic Gap
When the equilibrium real GDP falls short of potential GDP, it means the economy is producing below its full capacity. Resources, particularly labor, are likely underutilized, leading to unemployment rates higher than the natural rate.
Let's look at the options provided:
- Recessionary gap: This term specifically describes the situation where the equilibrium real GDP is below the potential GDP. It indicates that the economy is operating below its full potential, often associated with recessions or slowdowns. This matches the condition described in the question.
- Inflationary gap: This is the opposite situation, where equilibrium real GDP exceeds potential GDP. This happens when aggregate demand is very strong, pushing output temporarily beyond sustainable levels and typically leading to upward pressure on prices (inflation).
- Demand-side inflation: This refers to inflation caused by an increase in aggregate demand, which pulls up prices when the economy is near or at full employment (or in an inflationary gap situation). It describes a cause of inflation, not the state of output relative to potential.
- Supply-side inflation: Also known as cost-push inflation, this refers to inflation caused by decreases in aggregate supply, often due to rising production costs (like wages or raw materials). It describes a cause of inflation, not the state of output relative to potential.
Based on the definitions, the situation where equilibrium real GDP is less than potential GDP is precisely what is meant by a recessionary gap.
| Concept | Equilibrium Real GDP vs. Potential GDP | Economic Condition |
|---|---|---|
| Recessionary Gap | Below Potential GDP | Underutilization of resources, higher unemployment |
| Inflationary Gap | Above Potential GDP | Overutilization of resources, upward pressure on inflation |
| Zero Output Gap | Equal to Potential GDP | Economy operating at full potential/natural rate of unemployment |
Therefore, the correct term for the situation where the equilibrium level of real GDP falls short of potential GDP is a recessionary gap.

| Output Gap | Difference between actual GDP and potential GDP |
Additional Information on Recessionary Gaps and Potential GDP
A recessionary gap indicates that the economy is not performing as well as it could. This gap represents lost output and implies that there are unused productive resources, such as unemployed workers and idle factories. Governments and central banks often implement expansionary fiscal and monetary policies to try and close a recessionary gap by increasing aggregate demand. Policies might include increasing government spending, cutting taxes, or lowering interest rates. The goal is to stimulate economic activity and move equilibrium real GDP closer to potential GDP, thereby reducing unemployment and boosting overall output. Understanding the relationship between equilibrium GDP and potential GDP is crucial for analyzing the health of an economy and for designing appropriate macroeconomic stabilization policies.
