🏦 Part A: समष्टि अर्थशास्त्र (Macroeconomics) — 40 marks
Ch.1: परिचय (Introduction to Macroeconomics)
Macro vs Micro: Macro = पूरी अर्थव्यवस्था (GDP, Inflation, Unemployment) | Micro = Individual/Firm (Demand, Supply, Price)
Economy के Sectors: (1) Primary (Agriculture) (2) Secondary (Industry) (3) Tertiary (Services)
Circular Flow of Income: Two-sector (Households ↔ Firms), Three-sector (+Government), Four-sector (+Foreign sector)। Real flow (goods/services) vs Money flow (₹)।

Circular Flow of Income: Two-sector (Households ↔ Firms), Three-sector (+Government), Four-sector (+Foreign sector)। Real flow (goods/services) vs Money flow (₹)।
📊 Diagram: Circular Flow = ज़रूर बनाओ! Arrows दोनों तरफ — Real flow opposite to Money flow।
Ch.2: राष्ट्रीय आय का लेखांकन (National Income Accounting) ⭐⭐ MOST IMPORTANT!
🔑 Key Concepts — ये definitions रटो!
- GDP (Gross Domestic Product): देश की सीमा के अन्दर एक वर्ष में उत्पादित सभी final goods & services का मूल्य
- GNP = GDP + NFIA (Net Factor Income from Abroad)
- NDP = GDP - Depreciation
- NNP = GNP - Depreciation = National Income (at FC)
- NNPFC = NNPMP - Net Indirect Taxes (NIT = Indirect Tax - Subsidies)
- Market Price = Factor Cost + NIT
- Private Income = NI - Income of Public Sector - Net Retained Earnings + Transfer Payments + Interest on National Debt
- Personal Income = Private Income - Corporate Tax - Retained Earnings + Transfer Payments
- Personal Disposable Income = Personal Income - Direct Taxes
🔢 NUMERICAL FORMULAS — 10-15 marks!
Method 1 — Income Method:
NI = Compensation of Employees + Operating Surplus + Mixed Income of Self-employed
Operating Surplus = Rent + Interest + Profit (Corporate Tax + Dividends + Retained Earnings)
Method 2 — Expenditure Method:
GDPMP = C + I + G + (X - M)
C = Private Final Consumption, I = Gross Domestic Capital Formation (GDCF), G = Government Final Consumption, (X-M) = Net Exports
NNPFC = GDPMP - Depreciation + NFIA - NIT
Method 3 — Value Added / Product Method:
GVA = Value of Output - Intermediate Consumption
GDPMP = Σ GVA of all sectors + Net Indirect Taxes
Method 1 — Income Method:
NI = Compensation of Employees + Operating Surplus + Mixed Income of Self-employed
Operating Surplus = Rent + Interest + Profit (Corporate Tax + Dividends + Retained Earnings)
Method 2 — Expenditure Method:
GDPMP = C + I + G + (X - M)
C = Private Final Consumption, I = Gross Domestic Capital Formation (GDCF), G = Government Final Consumption, (X-M) = Net Exports
NNPFC = GDPMP - Depreciation + NFIA - NIT
Method 3 — Value Added / Product Method:
GVA = Value of Output - Intermediate Consumption
GDPMP = Σ GVA of all sectors + Net Indirect Taxes
⚡ Precautions:
• Intermediate goods exclude करो (Double counting से बचो!)
• Self-consumption include करो (imputed value)
• Second-hand goods exclude (but commission include)
• Transfer payments exclude (no production)
• Change in stock include करो
• Own-account production include (owner-occupied house rent)
• Intermediate goods exclude करो (Double counting से बचो!)
• Self-consumption include करो (imputed value)
• Second-hand goods exclude (but commission include)
• Transfer payments exclude (no production)
• Change in stock include करो
• Own-account production include (owner-occupied house rent)
🔄 GDP vs GNP vs NDP vs NNP:
GDP → +NFIA → GNP
GDP → -Depreciation → NDP
GNP → -Depreciation → NNP
MP → -NIT → FC
National Income = NNPFC 🎯
GDP → +NFIA → GNP
GDP → -Depreciation → NDP
GNP → -Depreciation → NNP
MP → -NIT → FC
National Income = NNPFC 🎯
Ch.3: मुद्रा और बैंकिंग (Money & Banking) ⭐
Money Supply: M1 = Currency + Demand Deposits + Other Deposits with RBI
M2 = M1 + Post Office Savings | M3 = M1 + Time Deposits (सबसे common) | M4 = M3 + Post Office Total Deposits
Central Bank (RBI) Functions: Note Issue (monopoly), Banker to Government, Banker's Bank, Controller of Credit, Lender of Last Resort, Foreign Exchange Management
Credit Control — Monetary Policy:
• Quantitative: Bank Rate ↑ = Credit ↓, Repo Rate, Reverse Repo, CRR, SLR, Open Market Operations (Buy/Sell securities)
• Qualitative: Margin Requirements, Moral Suasion (Request), Rationing of Credit
M2 = M1 + Post Office Savings | M3 = M1 + Time Deposits (सबसे common) | M4 = M3 + Post Office Total Deposits
Central Bank (RBI) Functions: Note Issue (monopoly), Banker to Government, Banker's Bank, Controller of Credit, Lender of Last Resort, Foreign Exchange Management
🔑 Credit Creation — Money Multiplier ⭐
- Money Multiplier = 1/LRR (Legal Reserve Ratio)
- LRR = CRR + SLR
- Total Credit = Initial Deposit × (1/LRR)
- Example: Deposit = ₹1000, LRR = 20% → Multiplier = 1/0.2 = 5 → Total Credit = ₹5000
• Quantitative: Bank Rate ↑ = Credit ↓, Repo Rate, Reverse Repo, CRR, SLR, Open Market Operations (Buy/Sell securities)
• Qualitative: Margin Requirements, Moral Suasion (Request), Rationing of Credit
🔢 Numerical: LRR = 10%, Initial Deposit = ₹5000
Money Multiplier = 1/0.10 = 10
Total Deposits = 5000 × 10 = ₹50,000
Total Credit Created = 50,000 - 5,000 = ₹45,000
Money Multiplier = 1/0.10 = 10
Total Deposits = 5000 × 10 = ₹50,000
Total Credit Created = 50,000 - 5,000 = ₹45,000
Ch.4: आय और रोज़गार का निर्धारण (Income & Employment Determination)
Aggregate Demand (AD) = C + I (Two-sector closed economy)
Aggregate Supply (AS) = C + S
Equilibrium: AD = AS → C + I = C + S → I = S (Saving-Investment approach)
Consumption Function: C = C̄ + bY (C̄ = autonomous consumption, b = MPC, Y = income)
Saving Function: S = -C̄ + (1-b)Y = -C̄ + sY (s = MPS)
MPC + MPS = 1 ⭐
Excess Demand (Inflationary Gap): AD > AS → Prices ↑ → Solution: ↓Government spending, ↑Tax
Deficient Demand (Deflationary Gap): AD < AS → Unemployment ↑ → Solution: ↑Government spending, ↓Tax
Aggregate Supply (AS) = C + S
Equilibrium: AD = AS → C + I = C + S → I = S (Saving-Investment approach)
Consumption Function: C = C̄ + bY (C̄ = autonomous consumption, b = MPC, Y = income)
Saving Function: S = -C̄ + (1-b)Y = -C̄ + sY (s = MPS)
MPC + MPS = 1 ⭐
🔑 Investment Multiplier ⭐
- K = 1/(1-MPC) = 1/MPS
- ΔY = K × ΔI
- MPC = 0.8 → K = 1/(1-0.8) = 1/0.2 = 5
- अगर Investment ₹100 बढ़े → Income = 5 × 100 = ₹500 बढ़ेगी
- MPC ↑ = K ↑ (Higher MPC = Higher multiplier)
Deficient Demand (Deflationary Gap): AD < AS → Unemployment ↑ → Solution: ↑Government spending, ↓Tax
Ch.5: सरकारी बजट (Government Budget) ⭐
🔑 Budget Components:
- Revenue Receipts: Tax (Direct + Indirect) + Non-Tax (Profits, Fees, Fines, Dividends) — न लौटाने वाली
- Capital Receipts: Loans, Disinvestment, Recovery of loans — liability बढ़ती है or asset घटता है
- Revenue Expenditure: Salary, Interest, Subsidies, Pension — asset नहीं बनता, liability नहीं घटती
- Capital Expenditure: Roads, Buildings, Loans given — asset बनता है or liability घटती है
🔄 Revenue vs Capital — Trick:
Revenue Receipt: कोई liability create नहीं होती, कोई asset कम नहीं होता
Capital Receipt: Liability बढ़ती है (loan लिया) या Asset कम होता है (disinvestment, recovery)
Revenue Expenditure: कोई asset create नहीं होता
Capital Expenditure: Asset बनता है या Liability कम होती है
Budget Deficits:Revenue Receipt: कोई liability create नहीं होती, कोई asset कम नहीं होता
Capital Receipt: Liability बढ़ती है (loan लिया) या Asset कम होता है (disinvestment, recovery)
Revenue Expenditure: कोई asset create नहीं होता
Capital Expenditure: Asset बनता है या Liability कम होती है
• Revenue Deficit = Revenue Expenditure - Revenue Receipts
• Fiscal Deficit = Total Expenditure - Total Receipts (excluding borrowings) ⭐
• Primary Deficit = Fiscal Deficit - Interest Payments
Fiscal Deficit Implications: Borrowing बढ़ती है → Interest burden → Future generations पर बोझ। लेकिन productive investment हो तो growth भी!
Ch.6: भुगतान शेष (Balance of Payments)
BOP = Current Account + Capital Account
Current Account: Trade in goods (Export - Import), Trade in services, Income (wages, investment income), Transfers (remittances)
• Trade Balance = Export of goods - Import of goods
• Current Account Deficit (CAD): Imports > Exports
Capital Account: FDI, FPI (Portfolio Investment), Loans (External borrowing/lending), Banking capital
Foreign Exchange Rate:
• Fixed: Government/Central Bank fixes rate
• Flexible/Floating: Market forces (demand-supply) decide
• Managed Floating: Market-based + RBI intervention (India follows this)
Demand for forex ↑ = ₹ depreciates (Dollar costly) | Supply of forex ↑ = ₹ appreciates (Dollar cheap)
Current Account: Trade in goods (Export - Import), Trade in services, Income (wages, investment income), Transfers (remittances)
• Trade Balance = Export of goods - Import of goods
• Current Account Deficit (CAD): Imports > Exports
Capital Account: FDI, FPI (Portfolio Investment), Loans (External borrowing/lending), Banking capital
Foreign Exchange Rate:
• Fixed: Government/Central Bank fixes rate
• Flexible/Floating: Market forces (demand-supply) decide
• Managed Floating: Market-based + RBI intervention (India follows this)
Demand for forex ↑ = ₹ depreciates (Dollar costly) | Supply of forex ↑ = ₹ appreciates (Dollar cheap)
🔄 Current vs Capital Account:
Current = Day-to-day trade (goods, services, transfers) — Short-term
Capital = Investment & borrowing (FDI, loans, FPI) — Long-term, asset creation/liability
Current = Day-to-day trade (goods, services, transfers) — Short-term
Capital = Investment & borrowing (FDI, loans, FPI) — Long-term, asset creation/liability
📈 Part B: व्यष्टि अर्थशास्त्र (Microeconomics) — 40 marks
Ch.1: परिचय (Introduction to Microeconomics)
Central Problems: What to produce? How to produce? For whom to produce?
Economy Types: Capitalist (Market) — Price mechanism | Socialist (Planned) — Government | Mixed — Both (India)
PPC (Production Possibility Curve): Shows maximum combinations of 2 goods। Concave to origin (increasing opportunity cost)। Shift right = growth, Left = destruction। Point on PPC = efficient, Inside = underutilization, Outside = not possible।
Economy Types: Capitalist (Market) — Price mechanism | Socialist (Planned) — Government | Mixed — Both (India)
PPC (Production Possibility Curve): Shows maximum combinations of 2 goods। Concave to origin (increasing opportunity cost)। Shift right = growth, Left = destruction। Point on PPC = efficient, Inside = underutilization, Outside = not possible।
📊 PPC Diagram: Draw concave curve, label axes with two goods, mark efficient/inefficient/unattainable points।
Ch.2-3: उपभोक्ता व्यवहार / माँग (Consumer Behaviour & Demand) ⭐⭐
Utility Approach: Total Utility (TU) maximum → Marginal Utility (MU) = 0। Consumer Equilibrium: MU/Price = MU/Price (for 2 goods)
Law of Demand: Price ↑ = Quantity Demanded ↓ (inverse relation, other things constant)
Exceptions: Giffen goods, Prestige goods, Expectation of future price rise, Necessities
Law of Demand: Price ↑ = Quantity Demanded ↓ (inverse relation, other things constant)
Exceptions: Giffen goods, Prestige goods, Expectation of future price rise, Necessities
🔑 Demand Concepts:
- Movement along curve: Price change → Extension (Price↓) / Contraction (Price↑)
- Shift of curve: Non-price factors → Increase (Right shift) / Decrease (Left shift)
- Factors shifting demand: Income, Tastes, Price of related goods (Substitute ↑ = Demand↑, Complement ↑ = Demand↓), Population, Expectations
- Price Elasticity = % Change in Qty / % Change in Price
- Elastic (Ed>1), Inelastic (Ed<1), Unitary (Ed=1), Perfectly elastic (Ed=∞), Perfectly inelastic (Ed=0)
📊 Diagrams ज़रूर बनाओ: (1) Demand curve (downward sloping) (2) Movement vs Shift (3) Elasticity types — 5 curves
Ch.3: उत्पादन एवं लागत (Production & Costs)
Production Function: TP, AP, MP relationships।
• TP increases at increasing rate → then decreasing rate → then falls
• AP = TP/L | MP = ΔTP/ΔL = TPn - TPn-1
• MP cuts AP at AP's maximum point ⭐
• When MP = 0, TP is maximum
Returns to a Factor: Increasing → Constant → Diminishing (Law of Variable Proportions)
• TP increases at increasing rate → then decreasing rate → then falls
• AP = TP/L | MP = ΔTP/ΔL = TPn - TPn-1
• MP cuts AP at AP's maximum point ⭐
• When MP = 0, TP is maximum
Returns to a Factor: Increasing → Constant → Diminishing (Law of Variable Proportions)
🔑 Cost Concepts:
- TC = TFC + TVC (Total = Fixed + Variable)
- AC = AFC + AVC = TC/Q
- MC = TCn - TCn-1 = ΔTC/ΔQ
- AC curve = U-shaped (falls → minimum → rises)
- MC cuts AC at AC's minimum point ⭐
- When MC < AC → AC falls | MC > AC → AC rises | MC = AC → AC minimum
- TFC is constant (horizontal line) | TVC starts from origin
Ch.4: आगम (Revenue)
TR = P × Q | AR = TR/Q = Price | MR = TRn - TRn-1
Perfect Competition: AR = MR = Price (horizontal line) — firm is price-taker
Imperfect Competition: AR > MR (both downward sloping, MR falls faster) — firm is price-maker
When MR = 0, TR is maximum
Perfect Competition: AR = MR = Price (horizontal line) — firm is price-taker
Imperfect Competition: AR > MR (both downward sloping, MR falls faster) — firm is price-maker
When MR = 0, TR is maximum
📊 Revenue Diagrams: (1) Perfect: AR=MR horizontal (2) Monopoly: AR above MR, both slope down (3) TR rises → max → falls
Ch.4: पूर्ति (Supply)
Law of Supply: Price ↑ = Quantity Supplied ↑ (direct relation)
Supply curve: Upward sloping
Movement vs Shift: Same as demand — Price change = movement, Non-price = shift
Factors shifting supply: Technology, Input prices, Taxes/Subsidies, Number of firms, Goals, Expectations
Price Elasticity of Supply = % Change in Qty Supplied / % Change in Price
• Straight line through origin → Es = 1 (always, regardless of slope)
• Meets Y-axis → Es > 1 | Meets X-axis → Es < 1
Supply curve: Upward sloping
Movement vs Shift: Same as demand — Price change = movement, Non-price = shift
Factors shifting supply: Technology, Input prices, Taxes/Subsidies, Number of firms, Goals, Expectations
Price Elasticity of Supply = % Change in Qty Supplied / % Change in Price
• Straight line through origin → Es = 1 (always, regardless of slope)
• Meets Y-axis → Es > 1 | Meets X-axis → Es < 1
Ch.5: बाज़ार संतुलन (Market Equilibrium)
Equilibrium: Demand = Supply (where curves intersect)
Excess Demand: QD > QS → Price ↑ → towards equilibrium
Excess Supply: QS > QD → Price ↓ → towards equilibrium
Effects of Shifts:
• Demand ↑ (Right shift): Equilibrium Price ↑, Quantity ↑
• Supply ↑ (Right shift): Equilibrium Price ↓, Quantity ↑
• Both ↑: Quantity ↑, Price depends on relative shift
Excess Demand: QD > QS → Price ↑ → towards equilibrium
Excess Supply: QS > QD → Price ↓ → towards equilibrium
Effects of Shifts:
• Demand ↑ (Right shift): Equilibrium Price ↑, Quantity ↑
• Supply ↑ (Right shift): Equilibrium Price ↓, Quantity ↑
• Both ↑: Quantity ↑, Price depends on relative shift
🔢 Numerical: Qd = 200 - 4P, Qs = -40 + 6P
Equilibrium: Qd = Qs → 200-4P = -40+6P → 240 = 10P → P = 24
Q = 200 - 4(24) = 104 units
Equilibrium: Qd = Qs → 200-4P = -40+6P → 240 = 10P → P = 24
Q = 200 - 4(24) = 104 units
Ch.6: बाज़ार के प्रकार (Forms of Market) ⭐⭐
🔑 Perfect Competition vs Monopoly vs Monopolistic:
- Perfect Competition: Many sellers, Homogeneous product, Free entry/exit, Perfect knowledge, AR=MR, Price-taker, Normal profit in long run
- Monopoly: Single seller, No close substitutes, Barriers to entry, AR>MR, Price-maker, Can earn super-normal profit
- Monopolistic Competition: Many sellers, Differentiated product (branding!), Free entry/exit, Selling costs (advertising), AR>MR, Normal profit in long run
- Oligopoly: Few sellers, Interdependence, Barriers to entry, Kinked demand curve
• If MR > MC → Produce more
• If MR < MC → Produce less
• MR = MC (MC rising) = Profit maximizing output ⭐
