Understanding Inflation: Causes, Effects, and Control
B1. Inflation
Inflation is the continuous and widespread process of rising prices in an economy over time.
Deflation
Deflation is the process in which prices are reduced in an economy over time in a continuous and widespread manner; it is the phenomenon contrary to inflation.
Measuring Inflation
The inflation rate between two periods is measured by the percentage increase in the CPI (Consumer Price Index) between the first and second period.
Formula: Inflation = ((CPI2 - CPI1) / CPI1) x 100
Causes of Inflation
- Demand-Pull Inflation: Any factor that shifts the aggregate demand curve to the right, such as an increase in public consumption spending or investment, generates inflationary pressure.
- Excess Money in Circulation: Uncontrolled growth of the money supply leads to excess demand. As the price of money decreases, the aggregate demand curve shifts to the right.
- Cost-Push Inflation: Supply shocks occur when price pressure is caused by an increase in the cost of inputs.
- Structural Inflation: Occurs when certain productive sectors cannot respond to a rapid increase in demand, causing rising prices throughout the production system.
Effects of Inflation
- Reduces the competitiveness of national products.
- Hampers the informational function of prices.
- Erodes the purchasing power of money.
- Adversely affects long-term investments.
- Hurts creditors and favors those in debt.
- Encourages the nominal price of money.
Control of Inflation
- Demand-Pull: Implement measures to reduce demand, such as raising interest rates.
- Excess Money: Control through monetary policy standards.
- Cost-Push: Addressed with structural reforms, such as the adjustment of salaries.
- Structural: Encourage competition in monopoly and oligopoly markets to lower prices.
