๐ Understanding Inflationary and Recessionary Gaps
In macroeconomics, potential GDP represents the level of output an economy can produce when all resources are fully employed. An inflationary or recessionary gap arises when the actual GDP deviates from this potential. These gaps act as signals to economists and policymakers, indicating whether the economy is operating above or below its sustainable capacity.
๐ Definition of an Inflationary Gap
An inflationary gap occurs when the actual GDP exceeds potential GDP. This situation implies that the economy is producing beyond its long-run sustainable capacity, leading to upward pressure on prices (inflation). Resources are being overutilized, and demand exceeds supply.
๐ Definition of a Recessionary Gap
A recessionary gap (also known as a deflationary gap) arises when the actual GDP is less than potential GDP. This signifies that the economy is underperforming, with resources not being fully utilized. There is spare capacity, leading to unemployment and potentially deflationary pressures.
