1️⃣ Introduction to Micro & Macro Economics
"Look at small details, understand the bigger picture!"
➡ Microeconomics – Study of consumers, sellers, demand, and supply.
➡ Macroeconomics – Study of the entire economy, GDP, inflation, and unemployment.
✅ Example:
Studying a single shop = Microeconomics
Studying India's entire economy = Macroeconomics
---
2️⃣ Utility Analysis
"Spend money to get satisfaction, but wisely!"
➡ Utility – Satisfaction gained from using a product.
➡ Marginal Utility – Additional satisfaction from consuming one more unit.
➡ Diminishing Marginal Utility – More consumption = Less satisfaction!
✅ Example:
The first slice of pizza is delicious.
By the fifth slice, satisfaction decreases!
---
3️⃣.1️⃣ Demand Analysis
"Price goes up, demand goes down. Price drops, demand rises!"
➡ Law of Demand – Price and demand have an inverse relationship.
➡ Giffen Goods – Essential goods whose demand increases even when prices rise (e.g., staple foods like bread).
✅ Example:
iPhone is expensive, so demand is limited.
If the price drops suddenly, more people buy it!
---
3️⃣.2️⃣ Elasticity of Demand
"Change the price, demand changes too!"
✔ Elasticity of Demand – Measures how demand changes due to price, income, or substitute goods.
🔹 Types:
✅ Price Elasticity – Higher price = Lower demand, and vice versa.
✅ Income Elasticity – Higher income = More demand for luxury goods.
✅ Cross Elasticity – If petrol prices rise, car demand drops!
📊 Elasticity Types:
🔸 Perfectly Elastic (Ed = ∞) – Small price change = Huge demand shift.
🔸 Inelastic (Ed < 1) – Price change has little effect on demand.
🚀 Factors: Product type, substitutes, income, time.
✅ Example:
iPhones are expensive, so fewer people buy them.
But during a sale, demand increases rapidly!
---
4️⃣ Supply Analysis
"Higher price, higher supply!"
➡ The supply curve is upward-sloping.
➡ Higher price = More production by sellers.
➡ Better technology = Increased supply.
✅ Example:
If wheat prices rise, farmers will produce more wheat.
---
5️⃣ Types of Markets
"Competition benefits customers, monopoly benefits sellers!"
➡ Perfect Competition – Many sellers, lower prices, better quality.
➡ Monopoly – One seller, controls price.
➡ Oligopoly – Few major sellers (e.g., telecom companies like Jio & Airtel).
✅ Example:
Zomato & Swiggy – Competition = Better offers for customers!
Indian Railways – No competition, so no choice!
---
6️⃣ Index Numbers
"Inflation rises, household budgets suffer!"
➡ CPI (Consumer Price Index) – Measures inflation.
➡ WPI (Wholesale Price Index) – Measures wholesale price changes.
✅ Example:
If petrol prices rise, inflation increases = CPI rises!
---
7️⃣ National Income
"How rich or poor is a country? This tells us!"
➡ GDP (Gross Domestic Product) – Total production within a country.
➡ GNP (Gross National Product) – GDP + Income from Indians abroad.
✅ Example:
India's GDP in 2024 was $3.7 trillion.
---
8️⃣ Public Finance in India
"Where does the government earn money, and where does it spend it?"
➡ Revenue Sources – Taxes (Income Tax, GST), government companies.
➡ Expenditures – Roads, railways, education, healthcare, military.

GST helps fund metro projects and highways.
---
9️⃣ Indian Money & Capital Market

If Sensex rises, investors profit!
If Sensex falls, investors face losses.
