On Day 19, you will focus on three fundamental concepts of Economy that are crucial for the UPSC Prelims:
- Gross Domestic Product (GDP) β Measurement, components, types, and importance.
- Inflation β Causes, types, impact, and control measures.
- Banking System β Structure, functions, RBIβs role, and monetary policies.
These topics are highly relevant because questions from basic economic concepts appear frequently in GS Paper 1. Having a strong foundation in these areas will help in understanding current affairs, economic policies, and government reports effectively.
π Topic 1: Gross Domestic Product (GDP)
What is GDP?
GDP (Gross Domestic Product) is the total monetary value of all final goods and services produced within a country’s borders in a given period (quarterly or annually). It is a key indicator of a countryβs economic performance and growth.
Methods to Calculate GDP
1οΈβ£ Production Method (Value Added Method)
- Calculates the value added at each stage of production in all sectors.
- Formula: GDP = Value of Output β Value of Intermediate Goods
2οΈβ£ Income Method
- Measures GDP by adding all incomes earned by factors of production.
- Formula: GDP = Wages + Rent + Interest + Profits
3οΈβ£ Expenditure Method
- Calculates GDP by total expenditure on final goods and services.
- Formula: GDP = C + I + G + (X – M)
- C = Private Consumption
- I = Investment
- G = Government Spending
- (X – M) = Net Exports (Exports – Imports)
Types of GDP
πΉ Nominal GDP β Measured at current market prices (includes inflation).
πΉ Real GDP β Adjusted for inflation, reflects true economic growth.
πΉ Per Capita GDP β GDP divided by the total population, indicating average income level.
Significance of GDP
β
Measures economic performance of a country.
β
Used for policymaking (fiscal & monetary policy).
β
Indicates standard of living.

π Topic 2: Inflation
What is Inflation?
Inflation refers to the general increase in prices of goods and services over time, reducing the purchasing power of money.
Types of Inflation
πΊ Demand-Pull Inflation β Caused by higher demand than supply.
πΊ Cost-Push Inflation β Due to increase in production costs (wages, raw materials).
πΊ Core Inflation β Excludes volatile items like food and fuel.
πΊ Hyperinflation β Extremely high and rapid inflation (e.g., Zimbabwe 2008).
Measuring Inflation in India
π Consumer Price Index (CPI) β Measures retail inflation, used by RBI for monetary policy.
π Wholesale Price Index (WPI) β Measures price change at the wholesale level.
Effects of Inflation
π¨ Negative Impacts
- Reduces purchasing power (money loses value).
- Increases cost of living.
- Hurts savings and fixed-income earners.
π‘ Positive Impacts
- Moderate inflation encourages investment and production.
- Governments benefit from higher tax revenues.
Control Measures
β
Monetary Policy β RBI increases interest rates to reduce money supply.
β
Fiscal Policy β Government reduces spending and increases taxes.
β
Supply-Side Policies β Boosts production to reduce shortages.
