What Is an Inflationary Gap?

What Is an Inflationary Gap?

Let me explain what an inflationary gap is. It occurs when the demand for goods and services outstrips production because of higher employment levels, more trade activity, or increased government spending. For this to qualify as inflationary, the real GDP has to be higher than the potential GDP. If the potential GDP is higher than the real one, you're looking at a deflationary gap instead.

Key Takeaways

Remember, the real GDP must exceed the potential GDP for it to be an inflationary gap. To close this gap, policies include cutting government spending, raising taxes, issuing bonds and securities, hiking interest rates, and reducing transfer payments. You can use fiscal policy to pull money out of circulation in the economy. A tight monetary policy reduces money available to consumers, which cuts demand.

Understanding Inflationary Gaps

Think about the inflationary gap as that point in the business cycle where the economy is expanding, and consumers are buying more goods and services. Demand goes up, but production can't keep pace, so prices rise to bring things back to equilibrium. The real GDP can go above the potential GDP, creating this gap. The formula is straightforward: Inflationary Gap = Actual GDP - Anticipated GDP.

Calculating Real Gross Domestic Product (GDP)

GDP measures the value of final goods and services produced in a period and bought by the end user in an economy. It includes market goods and services plus some nonmarket ones like government defense or education. In macroeconomic theory, the goods market sets the real GDP. Start by calculating nominal GDP: Y = C + I + G + NX, where Y is nominal GDP, C is consumption, I is investment, G is government expenditure, and NX is net exports.

To get real GDP, divide by the GDP deflator: Real GDP = Y / D. This accounts for inflation over time. Increases in consumption, investments, government spending, or net exports boost real GDP short-term. Real GDP shows true growth, adjusting for price changes in the economy.

Fiscal and Monetary Policy to Manage the Inflationary Gap

Governments turn to fiscal policy to shrink an inflationary gap by reducing money in circulation. This means cutting spending, increasing taxes, issuing bonds and securities, or reducing transfer payments. These steps lower demand for goods and services, easing inflation and restoring equilibrium.

Central banks, like the Fed, use tools to fight inflation too. Raising interest rates makes borrowing more expensive, which reduces money available to consumers and cools demand. Once equilibrium is back, they can adjust rates as needed.

How Do You Identify an Inflationary Gap?

You identify it as the difference between the full-employment GDP and the actual reported GDP. It shows extra output beyond what the economy would produce at the natural unemployment rate.

What Is the Difference Between Inflationary and Deflationary?

Inflation means prices of goods and services rise, cutting purchasing power. Deflation is the opposite, with falling general price levels.

What Causes an Inflationary Gap?

It comes from demand exceeding production, driven by high employment, more trade, or higher government spending.

How Do You Calculate the Inflationary Gap?

Simple: It's the actual GDP minus the anticipated GDP.

What Is a Recessionary Gap?

That's when the economy is below full-employment equilibrium.

The Bottom Line

An inflationary gap is the difference between current real GDP and potential GDP at full employment, with real GDP being higher. Governments use policies like spending cuts, tax hikes, and interest rate increases to close it.
