The GDP gap, a macroeconomic concept, refers to the difference between an economy's actual and potential Gross Domestic Product (GDP).

How It Works

The potential GDP is the maximum amount an economy can produce without causing inflation. The actual GDP is the current output. The GDP gap is calculated as:

Potential GDP - Actual GDP

If the result is positive, it's an output gap (recession). If negative, it's an inflation gap (boom).

Why It Matters

The GDP gap is crucial for policymakers. A persistent output gap signals an economy below its potential, indicating the need for stimulus policies to boost growth. Conversely, a large inflation gap may warrant tightening policies to prevent overheating. For instance, during the 2008 recession, the U.S. GDP gap was around 7%, highlighting the need for significant fiscal and monetary stimulus.
