In macroeconomics, the difference between current and potential GDP is known as a gap. This gap is caused by factors such as employment levels, government expenditure, and volume of trade activities. When these factors cause the real GDP to exceed the potential GDP, an inflationary gap is created.
This article talks about the significance of the inflationary gap in an economy.
An inflationary gap is a concept in macroeconomics that measures the difference between the prevailing GDP in the economy and the potential GDP i.e. the GDP when the economy operates at full employment. This gap is considered inflationary only if the current GDP is greater than the potential GDP. It occurs either due to an increase in aggregate demand or a reduction in aggregate supply.
All economies go through boom-bust cycles and experience inflationary gaps in the process. The economy in the United States was booming in 2006. The economic boom led to a lowering of unemployment rates, an increase in wages and also an increase in disposable income.
While this increased the demand, wage increases left less money for production and thus there was a gap in demand and output. Hence, the increase in purchasing power caused an inflationary gap.
Here is the inflationary gap formula:
Inflationary gap = Real or Actual GDP- Potential GDP
When an inflationary gap occurs, policies such as tax increases, decrease in government spending, issuing bonds and securities, and increasing interest rates are introduced.
This also indicates an expansion in the economy. When it occurs, there are more funds available in the economy and the interest in buying goods and services is more than before. On the other hand, when the real GDP is lower than the potential GDP, the gap caused is termed deflationary gap.
When there is inflation in the economy, the wages also rise, thereby leading to an increase in consumer demand. This creates an inflationary gap. This phenomenon is based on 2 economic concepts. The concepts are:
Economics describe this as the Phillips curve, which means a trade-off occurs between employment and inflation.
The concept of the natural rate of unemployment means that the economy is functioning in a way that fresh graduates are entering the workforce and non-performers are being terminated. It also includes businesses failing because of poor planning and management.
When the demand for labour increases, employers must increase the salary to attract more workers. This causes the employment rate to cross the natural rate. This accelerates inflation.
An inflationary gap is generally seen as a sign of an overheating economy, and it can have significant consequences if left unchecked. One of the main concerns is that it can lead to a rapid increase in prices, which can erode the purchasing power of people’s wages and savings. This can be especially problematic for those on fixed incomes or those who are reliant on their savings to meet their basic needs.
It can also create uncertainty and instability in financial markets, as investors may become concerned about the value of their assets if prices are rising rapidly. This can lead to a decline in the value of financial assets and a decrease in the overall level of economic activity.
It comprises potential gross domestic product and real GDP. It is the difference between real and potential GDP. Below are the factors that help to determine the real GDP of the economy:
Government expenditure includes income transfers, public consumption, social benefit transfers, etc.
This includes the output of unincorporated expenses, permits, household licences, etc.
Net exports refer to the difference between exports and imports. If the value is positive, i.e. exports are more than imports, it is called a trade surplus. However, if the imports are more than the exports, it is termed a trade deficit.
Investments include commercial expenses such as equipment purchases. However, they do not include the exchange of assets or the costs of buying financial assets.
Note that intermediate products and services are not included in the GDP calculation.
Below are the two primary ways to manage inflationary gaps and get higher price levels in market equilibrium:
The government enacts fiscal policies to control the supply of money. Contractionary fiscal policies help to decrease the money supply and reduce the demand. By enacting these policies, governments can manage the inflationary gaps.
Central banks control the supply of money by enacting monetary policies. Banks make borrowing money more difficult by increasing interest rates. This reduces the supply of money and thus the demand. Banks do this to manage the inflationary gaps.
The advantages of an inflationary gap are below:
Inflationary and recessionary gaps are opposite concepts. Recessionary gaps occur when the real GDP level of the country is lower than the potential GDP when the economy is at full-employment equilibrium. This means that at the full employment level, the actual output of the country is lower than the potential output.
Recessionary gaps are created during times of recession when the money supply is low, government spending is decreasing and consumer confidence is low. Government and central banks put expansionary policies in place to manage recessionary gaps. These policies help to increase demand by increasing the supply of money in the economy.
Governments fight the inflationary gap in the economy using deflationary fiscal policies. They do this by increasing taxes or reducing spending. This controls the currency in circulation. These policies are also known as contractionary fiscal policies.
Banks and government institutions control the money circulation in the economy by changing the lending rates.
Ans. In economics, the output gap is the difference between the real output of an economy and its anticipated output. Anticipated output is the maximum quantity of goods and services that an economy can turn when it is at its full capacity.
Ans. Full employment is an economic situation where all people looking for jobs can find one at the current wages and conditions. This condition doesn’t mean zero unemployment because some people will always be temporarily out of jobs, i.e. while changing jobs or for other reasons.
Ans. When the current GDP in the economy is lower than the potential GDP at full employment, the inflationary gap formula yields a negative value. This is termed a deflationary gap.
