Inflation
What is Inflation ?
In the layman’s understanding, inflation signifies a situation that is characterized by an increasing trend in the general price level. In other words, it refers to the persistent increase in the prices of an economy in a year. This means that when money income is expanding relatively to the output of work done by the productive agents for which it is the payment, leading to a rise in the price of the goods.
Causes of Inflation
- Demand-pull Inflation occurs when aggregate demand exceeds aggregate supply, often during periods of strong economic growth.
- Cost-push Inflation arises from increases in the cost of production, such as higher wages or raw material prices.
- Wage-price Inflation – workers demand higher wages to keep up with rising prices, and firms pass the cost on to consumers. In other words, wage-price spiral.
Effects of inflation
- Negative effects include reduced purchasing power, uncertainty in investment, income inequality, and loss of savings’ real value.
- Positive effects may include lower real debt burdens and incentives to invest rather than hold cash.
Mild inflation is normal in a growing economy, but hyperinflation or deflation (fall in prices) can be harmful and destabilising.
How to measure the rate of inflation?
The Consumer Price Index is a statistical device used to measure the rate of inflation. It shows price changes as percentages of prices in a base year. By comparing the current cost of the basket to a base year, economists can calculate the rate of inflation and monitor price stability.
Controlling Inflation
- Monetary policy: Monetary policy is the most common tool used to control inflation. When inflation is rising too fast, the central bank may increase interest rates. Higher interest rates make borrowing more expensive and saving more attractive. As a result, households and businesses reduce spending and investment, leading to lower demand in the economy. This reduction in aggregate demand (AD) helps to ease the upward pressure on prices. However, this policy may slow down economic growth and affect employment levels in the short run.
- Fiscal policy: Governments can also use fiscal policy to reduce inflation. One approach is to cut government spending, which directly reduces aggregate demand in the economy. Another is to increase taxes (such as income tax or VAT), which leaves households with less disposable income to spend, also reducing demand. By tightening fiscal policy, the government reduces the overall money flow in the economy, which helps to bring down demand-pull inflation. However, this policy can be politically unpopular and may reduce economic growth if applied too strictly.
- Supply-side policies: While monetary and fiscal policies tackle inflation from the demand side, they aim to increase the productive capacity of the economy and reduce the cost of production. For example, investing in better education and training increases labour productivity, and encouraging competition in markets can drive efficiency. Lower production costs and higher output reduce cost-push inflation, where firms pass on increased costs to consumers. Though supply-side policies are effective in the long run, they often take time to show results and may not be helpful in reducing short-term inflation.
