Concept of Inflation
- Inflation is a steady increase in the prices of goods and services in the economy.
- It is measured yearly and is usually represented as a rate: Rate of Inflation = (Price in this Period – Price in the Previous Period) X 100/Price in the Previous Period.
- It is measured by the Price Index.
Types of Inflation
- Creeping Inflation: A slow yet continuous increase in prices generally in the range of 2% to 3%.
- Walking Inflation or Trotting Inflation: Rate of price rise exceeding 2%, usually in the range of 3% to 10%.
- Galloping Inflation: Rate of price rise exceeding 10% and below 50%, which makes it unbearable for businesses and employees to maintain their incomes in comparison with their costs and prices.
- Hyperinflation: A condition of inflation wherein the rate of increase of prices is alarmingly high, usually more than 50% per month.
Types of Inflation based on Causes
- Demand-Pull Inflation: Increase in prices due to an increase in aggregate demand and consumption.
- Cost-Push Inflation: Increase in prices due to an increase in the cost of ‘factors of production’.
- Supply-Shock Inflation: A rise in prices due to an unexpected or unforeseen sharp fall in the supply of commodities.
- Structural Inflation or Bottleneck Inflation: A rise in prices due to deficiencies in the economy leading to shortages of supply.
- Protein Inflation: A rise in demand and prices of protein-rich items due to changing dietary habits.
Measures of Inflation
- In India, two indicators for measurement are used, which are the Wholesale Price Index and the Consumer Price Index.
- The third is GDP Deflator.
Indian Market Overview
Wholesale Price Index (WPI)
- It measures average change in commodity prices in the wholesale market.
- The three commodity groups are: Primary Products, Fuel and Power, and Manufactured Products.
- Weights assigned to each commodity are on the basis of production value net of net imports.
- Compiled and published monthly by the Office of Economic Advisor, Ministry of Commerce and Industry.
- Base year for WPI: 2011-12.
Consumer Price Index (CPI)
- Average change in prices paid by the ultimate consumers for a basket of goods and services over time.
- The types of CPIs are due to the diversity in the condition of society.
- Industrial Workers Price Index (CPI-IW): Measures commodity basket of industrial workers
- Consumer Price Index for Urban Non-Manual Employees (CPI-UNME): It measures the change in commodity baskets consumed by nonmanual employees.
- CPI for Rural Laborers and Agricultural Laborers (CPI-AL&RL): Measures change in commodity baskets consumed by rural laborers.
New CPIs
- Covers all segments of the population of India.
- Compilated and published by the Central Statistical Organisation (CSO) for All India Level and the State/UT Level.
- New Indices: CPI (Rural), CPI (Urban), and CPI (Combined).
- Reserve Bank of India (RBI) uses CPI (Combined) as the sole inflation measure for monetary policy.
Comparative Analysis of Wholesale Price Index (WPI) and Consumer Price Index (CPI)
- WPI and CPI are on the same base year, 2011-12, but with different commodity numbers and weights.
- Inflation based on WPI is generally low, while inflation based on CPI is generally high.
- WPI is not very suitable for monetary policy decisions, while CPI is very suitable.
Producer Price Index (PPI)
- PPI measures the average change in selling prices received by domestic producers over time.
- It measures price changes from the perspective of producers.
GDP Deflator
- GDP Deflator is the ratio between GDP at Current Prices and GDP at Constant Prices.
- It indicates the level of price rise by indicating changes in price levels.
- It is a better measure of inflation as it takes into account all goods and services of the economy.
- Redistribution of Income and Wealth: It causes loss to some group and gains to others.
- Borrower Vs Lender: The borrower is the gainer, the lender is the loser.
- Producer Vs Consumer: Consumers have to pay more money to producers for the same amount of goods and services.
- Flexible Income Group Vs Fixed Income Group: Flexible income groups aren’t affected; fixed-income groups lose since their purchasing power declines.
- Debentures or Bond Holders Vs Issuers: Issuers gain; bond holders lose.
- Equity Holders: In the inflationary condition, equity holders earn more income.
Effects of Inflation on Production and Consumption
- Increased prices can reduce the demand for goods and services, thereby reducing production and diverting investment to other sectors.
- Inflation decreases the value of money, hence a wise economic decision to deposit money in banks.
- In the short term, inflation is generally associated with economic growth and employment; however, in the long run, it may not always be so.
- High prices reduce exports and increase imports from other countries, which leads to an adverse Balance of Payment (BoP).
- High import and low export means high demand for foreign currencies that depreciate the domestic currency.
Measures to Control Inflation
- Investors compute a “Real Interest Rate” by adjusting the “Nominal Interest Rate” for inflation.
- Inflation Tax is an implicit tax resulting from the impact of inflation on nominal assets, like cash, bonds, and savings accounts.
- Phillips Curve is the inverse relationship between the unemployment rate and inflation.
- Monetary Measures: The RBI uses monetary instruments to reduce the money supply of the market, which diminishes demand and consequently prices.
- Fiscal Measures: Lesser government expenditure reduces demand and lowers price level.
- Trade Measures: To curb the shortage of goods in the domestic market, various trade measures could be taken.
- Administrative Measures: A logical Wage Policy helps control the cost of production and prices.
