What is meant by the term "output gap"?

• A. The difference between current and past output
• B. The difference between actual economic output and potential output
• C. The gap between demand and supply in the market
• D. The difference between actual employment and unemployment rates

Answer: (B)

The term "output gap" refers to the difference between actual economic output and potential output, which is represented by option B. Potential output is the level of economic activity that an economy can sustain over the long term without increasing inflation, accounting for factors like technology, resources, and labor. When actual output falls short of potential output, the economy experiences a negative output gap, indicating underutilization of resources. Conversely, when actual output exceeds potential output, it suggests the economy is overheating, which can lead to inflationary pressures.

In comparison, the other options do not accurately capture the essence of the output gap. For instance, the difference between current and past output does not account for potential output and is more about historical performance rather than the economy's capability. The gap between demand and supply refers to market dynamics rather than aggregate economic performance related to output. Lastly, the difference between actual employment and unemployment rates does not directly relate to output levels, focusing instead on labor market conditions rather than the overall output of the economy. Thus, option B is the most comprehensive and accurate definition of the output gap.
