An output gap refers to the difference between the actual level of output in an economy and the potential level of output. The potential level of output is often referred to as the full-employment output. Understanding output gaps is crucial for analyzing economic performance and the effectiveness of economic policies.
Potential Output
Potential output represents the maximum level of output an economy can produce when all its resources (land, labor, capital, and technology) are fully employed. It's a theoretical concept and is not directly observable.
Factors influencing potential output include:
Availability of labor and capital
Technological progress
Productivity levels
Government regulations
Output Gap Definitions
There are two main types of output gaps:
Positive Output Gap: Occurs when the actual level of output is greater than the potential level of output. This often leads to inflationary pressures.
Negative Output Gap: Occurs when the actual level of output is less than the potential level of output. This often leads to economic recession or unemployment.
Causes of Output Gaps
Output gaps can arise due to various factors:
Demand-Pull Gaps: These occur when aggregate demand is higher than potential output. This can be caused by increased consumer spending, investment, government spending, or net exports.
Cost-Push Gaps: These occur when the cost of production for firms increases, leading to a decrease in output. This can be caused by rising wages, higher raw material prices, or increased taxes.
Positive Output Gap: Inflationary Pressures
A positive output gap means the economy is producing more than it is capable of sustainably. This excess demand can lead to:
Rising Inflation: As demand exceeds supply, prices tend to increase.
Decreasing Unemployment: Firms are likely to hire more workers to meet the higher demand.
Increased Resource Utilization: More of the economy's resources are being used.

Negative Output Gap: Recession and Unemployment
A negative output gap means the economy is producing less than it is capable of. This can lead to:
Falling Output: The overall level of production in the economy is lower than it could be.
Rising Unemployment: Firms may lay off workers due to lower demand.
Falling Investment: Businesses are less likely to invest when demand is weak.
Governments and central banks can use various policies to try and close output gaps:
To address a Positive Output Gap:
Monetary Policy: Raising interest rates to reduce demand.
Fiscal Policy: Reducing government spending or increasing taxes to reduce demand.
To address a Negative Output Gap:
Monetary Policy: Lowering interest rates to encourage borrowing and investment.
Fiscal Policy: Increasing government spending or reducing taxes to boost demand.

Suggested diagram: A graph showing the short-run aggregate supply (SRAS) and short-run aggregate demand (SRAS) curves. A positive output gap would be represented by the actual output being to the right of the potential output on the aggregate output curve. A negative output gap would be represented by the actual output being to the left of the potential output.
