• Schools: Classical vs. Keynesian economics.
1.2 Context of the Present Book
• Capitalist Economy: Private ownership, wage labour, profit motive.
• 4 Sectors: Households (consume, save), Firms (produce, invest), Government (tax, spend), External Sector (trade).
• Key Concepts: Economic agents, unemployment, factors of production, wage rate, investment.


Chapter 2: National Income Accounting
Page Range: 9-35
2.1 Basic Concepts
• Factors of Production & Remuneration: Labour→Wages, Capital→Interest, Land→Rent, Entrepreneurship→Profit.
• Goods: Final (end-use) vs. Intermediate (raw material).
• Stocks vs. Flows: Stocks (at a point in time, e.g., capital) vs. Flows (over a period, e.g., income).
• Investment: Gross Investment = Net Investment + Depreciation.
• Key Terms: Depreciation, Inventories.
2.2 Circular Flow & National Income Calculation
• Circular Flow: Illustrates income flow between households and firms.
o Leakages: Savings, Taxes, Imports (S, T, M).
o Injections: Investment, Govt. Spending, Exports (I, G, X).
• 3 Methods to Calculate GDP:
o Product (Value Added): GDP = ΣGVA of all firms. (Avoids double counting).
o Expenditure: GDP = C + I + G + (X − M).
o Income: GDP = Wages + Rent + Interest + Profits.
2.3 Macroeconomic Identities
• GNP = GDP + Net Factor Income from Abroad (NFIA).
• NNP = GNP − Depreciation.
• National Income (NI) = NNP at Factor Cost = NNP at Market Price − Net Indirect Taxes.
• Personal Disposable Income (PDI) = Personal Income − Personal Taxes.
2.4 Nominal and Real GDP
• Nominal GDP: At current prices.
• Real GDP: At constant (base-year) prices.
• GDP Deflator = (Nominal GDP / Real GDP) × 100.
• Price Indices: CPI (Consumer) & WPI (Wholesale).
2.5 GDP and Welfare
• Limitations: Ignores income distribution, non-monetary exchanges (e.g., housework), and externalities (e.g., pollution).

3.1 Functions of Money
• Roles: Medium of Exchange, Unit of Account, Store of Value.
• Solves the “double coincidence of wants” problem of barter systems.
3.2 Demand for and Supply of Money
• Demand:
o Transaction Motive: MTd = kPY (depends on income).
o Speculative Motive: Inversely related to interest rates.
o Liquidity Trap: Money demand becomes infinite at very low interest rates.
• Supply:
o M1 (Narrow Money) = Currency + Demand Deposits.
o M3 (Broad Money) = M1 + Net Time Deposits.
3.3 Money Creation by Banking System
• Process: Banks create credit from deposits.
• Money Multiplier = 1 / CRR (Cash Reserve Ratio).

• MPS (Marginal Propensity to Save) = 1 − MPC.
• Investment: Assumed autonomous (I = Ī).
4.2 Equilibrium in Two-Sector Model

• Formula: Y = (C̄ + Ī) / (1 – c).
4.3 The Multiplier Mechanism
• Investment Multiplier = ΔY / ΔI = 1 / (1 – c) = 1 / MPS.
• A change in autonomous spending (A) leads to a larger change in income (Y).
4.4 Key Concepts

• Revenue Deficit = Revenue Expenditure − Revenue Receipts.
• Fiscal Deficit = Total Expenditure − (Revenue Receipts + Non-debt Capital Receipts).
• Primary Deficit = Fiscal Deficit − Interest Payments.
5.3 Fiscal Policy & Multipliers
• Govt. Expenditure Multiplier = ΔY / ΔG = 1 / (1 – c).
• Tax Multiplier = ΔY / ΔT = -c / (1 – c).
• Balanced Budget Multiplier = 1.
• Automatic Stabilizers: Proportional taxes reduce economic volatility.

4.2 Revenue
• For a price-taking firm: Price (p) = Average Revenue (AR) = Marginal Revenue (MR).
4.3 Profit Maximization

4.4 Supply Curve of a Firm
• Short Run: Rising part of SMC curve above min AVC.
• Long Run: Rising part of LRMC curve above min LRAC.
4.7 Price Elasticity of Supply (es)
• Formula: es = (%Δ Quantity Supplied) / (%Δ Price).


Chapter 5: Market Equilibrium
Page Range: 1-20
5.1 Equilibrium, Excess Demand, Excess Supply
• Equilibrium: Where market demand equals market supply (qD = qS).
• Excess Demand (Shortage): qD > qS, price rises.
• Excess Supply (Surplus): qS > qD, price falls.
• Shifts: Changes in demand/supply lead to new equilibrium.
• Free Entry/Exit: In the long run, firms earn zero economic profit (p = min AC).
5.2 Applications
• Price Ceiling: Max price set below equilibrium → Shortage.
• Price Floor: Min price set above equilibrium → Surplus.
