Rapid summary for last-minute revision before your exam.

Basic Economic Concepts

• Scarcity: Unlimited wants vs limited resources. Foundation of economics.
• Opportunity Cost: Cost of the next best alternative foregone. Decision-making core.
• Demand & Supply: Law of Demand (price ↑ → demand ↓). Law of Supply (price ↑ → supply ↑). Market equilibrium (D = S).
• Price Elasticity of Demand (PED): % change in Qd / % change in P. |PED| > 1 = elastic, < 1 = inelastic. Luxury vs necessity.
• Market Structures:
  • Perfect Competition: Many firms, identical product, no pricing power.
  • Monopoly: Single firm, unique product, high barriers to entry.
  • Monopolistic Competition: Many firms, differentiated products (soap, toothpaste).
  • Oligopoly: Few large firms (airlines, telecom). Interdependence, game theory.
• GDP: Gross Domestic Product — total value of goods/services produced in a country in a year. Nominal vs Real GDP. GDP Growth Rate.
• GNP: Gross National Product = GDP + Net Factor Income from abroad.
• Inflation: Rise in general price level. CPI (Consumer Price Index), WPI (Wholesale Price Index). Core inflation (excludes food and fuel).
• Types of Inflation: Creeping (slow), Trotting (moderate), Galloping (high), Hyperinflation (失控).
• Deflation: Falling prices. Dangerous — leads to reduced spending, production cuts.
• Stagflation: High inflation + high unemployment + low growth (1970s oil crisis).
• Fiscal Policy: Government spending and taxation. Expansionary (↑ spending, ↓ tax) vs Contractionary. Budget deficit, surplus.
• Monetary Policy: Central bank control of money supply and interest rates. RBI’s tools: Repo rate, Reverse repo rate, CRR, SLR, MSF.

Money, Banking & Finance

• Functions of Money: Medium of exchange, Store of value, Unit of account, Standard of deferred payment.
• Central Bank (RBI): Banker’s bank, Government’s bank, Lender of last resort. Issues currency, controls credit.
• Commercial Banks: Accept deposits, lend money, create credit. Balance sheet: Assets (loans) vs Liabilities (deposits).
• Money Multiplier: 1/CRR. Deposit expansion multiplier. How much banks can create from initial deposit.
• NPAs: Non-Performing Assets. Gross NPA vs Net NPA. Recovery rate, provision coverage ratio.
• RBI Key Rates:
  • Repo Rate (repurchase rate): Rate at which RBI lends to banks (short-term).
  • Reverse Repo Rate: Rate at which RBI borrows from banks.
  • CRR (Cash Reserve Ratio): % of deposits banks must keep with RBI.
  • SLR (Statutory Liquidity Ratio): % of deposits in gold/government securities.
  • MSF (Marginal Standing Facility): Emergency borrowing from RBI (above repo).

International Trade

• Balance of Payments (BoP): Current Account + Capital Account + Financial Account.
• Current Account: Trade in goods (exports-imports), services, primary income (interest, dividends), secondary income (remittances).
• Capital Account: Transfer of capital assets, acquisition/disposal of assets.
• Trade Deficit: Imports > Exports (in goods). Current Account Deficit (CAD) — broader.
• FOREX Market: Foreign exchange. Exchange rate systems: Fixed (Pegged), Floating (Market-determined), Managed float.
• Devaluation vs Revaluation: Official downward vs upward adjustment of currency value under fixed system.
• Bretton Woods System: Post-WWII fixed exchange rates (gold standard). Dollar pegged to gold ($35/oz). Collapsed 1971 (Nixon Shock). Led to fiat currency system.

⚡ Exam Tips for XAT:

• XAT’s Decision Making and General Awareness sections test understanding of business/economic news.
• Focus on: How does RBI’s rate cut affect economy? What does a trade deficit mean? Why is fiscal deficit important?
• Recent economic policy decisions (budget, GST changes, RBI decisions) are frequently asked.

Standard content for students with a few days to months.

Macroeconomics — Detailed

National Income Accounting:

• GDP (Gross Domestic Product): Market value of all final goods/services produced within geographical boundaries in a year.
• GNP (Gross National Product): GDP + Net Factor Income from abroad (NFIA).
• NNP (Net National Product): GNP - Depreciation (Capital consumption allowance).
• National Income (NI): NNP - Indirect taxes + Subsidies. Or: Compensation of employees + Proprietors’ income + Rental income + Corporate profits + Interest.
• Per Capita Income: National Income / Population. Used to compare development levels.
• GDP Deflator: Nominal GDP / Real GDP × 100. Measures inflation.
• Purchasing Power Parity (PPP): Exchange rate that equalizes purchasing power of two currencies. Used for realistic international comparisons. India PPP GDP is much higher than nominal GDP.
• Human Development Index (HDI): Composite of health (life expectancy), education (mean/expected schooling), income (GNI per capita). India ranked 134/189 (2023) — Low Human Development.

Circular Flow of Income:

• Households → factors of production (land, labor, capital, entrepreneurship) → Firms.
• Firms → goods and services → Households.
• Leakages (savings, taxes, imports) = Injections (investment, government spending, exports).
• Equilibrium when Leakages = Injections.

Consumption, Savings & Investment:

• Consumption Function: C = C₀ + cY (C₀ = autonomous consumption, c = marginal propensity to consume (MPC), Y = income).
• Marginal Propensity to Consume (MPC): ΔC/ΔY. Between 0 and 1.
• Marginal Propensity to Save (MPS): ΔS/ΔY. MPS = 1 - MPC.
• Multiplier Effect: K = 1/(1-MPC) = 1/MPS. Government spending multiplier, tax multiplier.
• Investment: GFCF (Gross Fixed Capital Formation). Private vs Public investment. Autonomous vs Induced investment.

Keynesian Economics:

• Aggregate Demand (AD) = C + I + G + (X-M).
• Short-run aggregate supply (SRAS). Long-run LRAS (vertical at full employment).
• Recessions: AD shifts left → output ↓, unemployment ↑. Stimulus (↑G, ↓tax) shifts AD right.
• Paradox of Thrift: If everyone saves more, total savings don’t increase (reduced consumption → lower income → lower savings).

Money & Banking — Detailed:

Money Supply Measures (RBI):

• M0: Currency in circulation + Bankers’ deposits with RBI (high-powered money).
• M1: M0 + Demand deposits (current + savings accounts) + Other deposits with RBI.
• M2: M1 + Savings deposits with post office savings banks.
• M3: M3 (Broad money) = M1 + Time deposits with banks.
• M4: M3 + All deposits with post office savings banks (excluding NSC).
• Most commonly used: M3.

Credit Creation Process:

• Banks create money by lending. Initial deposit → Fractional reserve → Multiple credit creation.
• Money Multiplier = 1/CRR. If CRR = 4%, multiplier = 25. If CRR = 20%, multiplier = 5.
• Actual multiplier may be less due to cash drain, precautionary reserves.

Non-Performing Assets (NPAs):

• Sub-standard: NPA for < 12 months.
• Doubtful: NPA for > 12 months.
• Loss Assets: Uncollectible. Written off.

RBI’s Monetary Policy Framework:

• 5-year monetary policy framework agreement (2015) with government.
• Target: CPI inflation of 4% (+/- 2%). RBI uses repo rate to achieve this.
• When inflation above target → contractionary (raise rates). When below → expansionary (cut rates).
• Standing Deposit Facility (SDF): New tool (2022) — allows RBI to absorb excess liquidity without securities.

Inflation — Detailed:

Demand-Pull Inflation: Too much money chasing too few goods. AD shifts right. Cost-Push Inflation: Rising input costs (oil shock, supply disruptions). SRAS shifts left. Built-in Inflation: Expectations of future inflation → current wage demands → price increases.

Phillips Curve: Inverse relationship between unemployment and inflation in short run. In long run, vertical (no tradeoff). Expectation-augmented Phillips Curve.

Indexation: Adjusting wages, contracts for inflation. Used in India for DA (Dearness Allowance) for employees.

Deflation: Sustained fall in price level. Debt deflation (debt becomes more expensive). Japan lost decades (1990s-2000s).

• Revenue Deficit: Revenue expenditure - revenue receipts. Indicates consumption without investment.
• Primary Deficit: Fiscal deficit - interest payments. Shows borrowing need excluding interest.

FRBM Act (Fiscal Responsibility and Budget Management Act, 2003):

• Target: Eliminate revenue deficit and reduce fiscal deficit to 3% of GDP.
• Not strictly adhered to. Government raised FD target to 9.5% (COVID year 2020-21), then gradually reducing.
• Fiscal consolidation roadmap: Medium-Term Fiscal Policy (MTFP).

🔴 Extended — Deep Study (3mo+)

Comprehensive coverage for students on a longer study timeline.

Advanced Economic Theory

Theories of Value:

• Labor Theory of Value (Classical): Adam Smith, David Ricardo. Value = amount of labor embodied. Problem: doesn’t account for capital.
• Marginalist Revolution (1870s): Value determined by marginal utility (subjective). Jevons, Menger, Walras (Marginalist Trinity).
• Neoclassical Synthesis: Marshall combined supply (cost of production) and demand (marginal utility). Price = intersection of MR and MC.
• Modern: Supply-demand framework. General Equilibrium (Walras).

Theories of Economic Growth:

• Classical: Malthus (population growth vs food supply — iron law of wages). Diminishing returns.
• Harrod-Domar Model: Savings rate and capital-output ratio determine growth. S/Y = g × k. Problem: assumes fixed coefficients.
• Solow-Swan Model (1956): Neo-classical. Adds labor and technology to capital. Convergence hypothesis. TFP (Total Factor Productivity) important. Shows diminishing returns to capital.
• Endogenous Growth Theory (Romer, Lucas): Knowledge spillovers, R&D, human capital drive growth (internal to system).
• Lewis Model (Dual Sector): Unlimited labor supply from traditional agriculture. Structural transformation from agriculture → industry. Lewis turning point (when surplus labor dries up).
• Poverty Trap: Low income → low savings → low investment → low income. Multiple equilibria. Need big push or critical minimum effort.

Microeconomics — Advanced:

Consumer Behavior:

• Utility: Total satisfaction. Marginal Utility (MU) = ΔTU/ΔQ. Law of Diminishing MU.
• Indifference Curves: Consumer preferences. Budget line (constraint). Consumer equilibrium at tangency. Substitutes vs Complements. Inferior goods vs Normal goods.
• Revealed Preference: Samuelson. If consumer buys X at lower price, X is preferred when Y’s price rises.

Theory of Production:

• Production Function: Q = f(L, K). Short run (variable factors, fixed capital). Long run (all factors variable).
• Law of Variable Proportions (Short Run): TP, MP, AP. Increasing, diminishing, negative returns.
• Returns to Scale (Long Run): Increasing (α+β > 1), Constant (α+β = 1), Decreasing (α+β < 1). Cobb-Douglas: α+β = 1 (constant returns).
• Isoquants: Same output. MRTS (Marginal Rate of Technical Substitution). Isocosts (equal cost lines). Cost minimization.

Cost Theory:

• Short Run: TFC (fixed), TVC (variable). TC = TFC + TVC. AFC (TFC/Q), AVC (TVC/Q), AC (TC/Q), MC (ΔTC/ΔQ). U-shaped AC and AVC curves (due to Law of Variable Proportions).
• Long Run: All costs variable. LAC (Long Run Average Cost) = envelope of short-run AC curves. Economies of scale (downward sloping LAC). Diseconomies (upward). Minimum Efficient Scale.

Market Structures — In Depth:

Perfect Competition:

• Assumptions: Many buyers/sellers, identical products, perfect information, free entry/exit, no transaction costs.
• In short run: P = MR = MC (profit max). Can earn economic profit or loss.
• In long run: P = LAC (no economic profit). No entry/exit incentive. Allocatively efficient (P=MC) and productively efficient (P=minimum LAC).
• Examples: Agricultural markets (wheat, rice), stock markets (theoretical, not real).

Monopoly:

• One firm, unique product, high barriers. No close substitutes.
• Demand = Market demand (downward sloping). MR = P(1+1/|ε|). MR < P.
• Profit maximization: MR = MC. Can earn economic profit in both short and long run (no entry).
• Price discrimination: 1st degree (perfect — each consumer pays max price), 2nd degree (block pricing), 3rd degree (different groups — students, seniors).
• Natural monopoly: LAC always declining (high fixed costs, low marginal costs). Example: Utilities (electricity, water). Regulated.
• Deadweight loss: Monopoly creates DWL (P > MC). Allocatively inefficient.
• Efficiency loss: X-inefficiency (no incentive to minimize costs).

Monopolistic Competition:

• Many firms, differentiated products (branding, quality, design). Some pricing power.
• Short run: MR = MC → economic profit possible.
• Long run: Entry drives profit to zero (like perfect competition). P > LAC, P > MC.
• Excess capacity: Firms operate below minimum LAC (inefficient).
• Non-price competition: Advertising, product differentiation.

Oligopoly:

• Few firms, interdependence. High barriers. Strategic interaction (game theory).
• Game Theory:
  • Nash Equilibrium: Each player chooses best strategy given others’ strategies.
  • Prisoner’s Dilemma: Individual rationality vs collective rationality. Both lose.
  • Dominant strategy: Best regardless of opponent.
• Models:
  • Cournot ( quantity): Firms choose output simultaneously. Reaction functions. Duopoly.
  • Bertrand (price): Firms choose price. Typically leads to competitive outcome (Price = MC) — butBertrand Paradox.
  • Stackelberg (leader-follower): One firm leads in quantity.
  • Cartel (collusion): Firms act as monopoly, share profit. Prisoner’s dilemma (temptation to cheat). OPEC example.
• Kinked Demand Curve (Sweezy): One firm raises price → competitors don’t follow. One firm lowers price → competitors match. Rigid prices, price stability.
• Entry deterrence: Limit pricing (price below minimum LAC to deter entry), predatory pricing (below cost, drive out competitor).

Macroeconomics — Advanced:

IS-LM Model (Hicks-Hansen):

• IS Curve (Investment-Saving): Goods market equilibrium. Downward sloping (r ↓ → I ↑ → AD ↑ → Y ↑). Equation: Y = C(Y-T) + I(r) + G.
• LM Curve (Liquidity Preference-Money): Money market equilibrium. Upward sloping (Y ↑ → Md ↑ → r ↑ to restore equilibrium).
• Equilibrium: IS = LM. Determines Y* and r*.
• Policy: Expansionary fiscal policy → IS shifts right → Y ↑, r ↑ (crowding out — higher interest rates reduce private investment).
• Limitation: Keynesian short-run. Classical long-run (vertical LRAS).

AD-AS Model:

• Aggregate Demand (AD): Inverse relationship between price level and real GDP. Wealth effect, interest rate effect, exchange rate effect.
• Short-Run AS (SRAS): Upward sloping (wages sticky in short run). Keynesian range (horizontal), Intermediate, Classical range (vertical).
• Long-Run AS (LRAS): Vertical at full employment output (Y*). Potential GDP. Determined by productive capacity (technology, resources, institutions).
• Shocks: AD shock (demand side — oil crisis, financial crisis). AS shock (supply side — oil embargo, pandemic).

Phillips Curve:

• Short Run: Negative relationship between unemployment and inflation (policy tradeoff).
• Long Run: Vertical at NAIRU (Non-Accelerating Inflation Rate of Unemployment). No tradeoff.
• Expectation-augmented Phillips Curve: π = πe - β(u - u*) + supply shock. Adaptive expectations (past inflation).
• Rational Expectations (Lucas): People use all available information. Only unexpected policy matters.

Monetarism (Milton Friedman):

• Money supply is key driver of inflation. “Inflation is always and everywhere a monetary phenomenon.”
• Money demand stable function. Rejected Keynesian interest rate approach.
• Natural Rate of Unemployment (NAIRU).
• Critique of Phillips Curve: Long-run vertical.

Supply-Side Economics (Reaganomics):

• Laffer Curve: High tax rates → lower revenue (discourages work, investment). Tax cuts stimulate growth → higher revenue.
• Supply-side: Reduce marginal tax rates, deregulation, control money supply.
• Criticism: Laffer Curve empirical support weak.

Economic Development:

• Deals: Tata-Corus (2007), Vodafone-Hutchison Essar (2007), Walmart-Flipkart (2018), Facebook-WhatsApp (2014 — global), Microsoft-LinkedIn (2016).
• Antitrust/Competition Law: CCI (Competition Commission of India). Section 4 (abuse of dominance), Section 5 (combinations — threshold-based).
• Takeover: Open offer under SEBI SAST. When acquirer crosses 25% threshold, must make open offer for 26% additional shares.

Key Global Economic Issues:

• Recession: Two consecutive quarters of negative GDP growth. Global recession 2009 (post-2008), 2020 (COVID). Risk of recession 2023-24 (inflation, rate hikes).
• Global Inflation: Post-COVID supply disruptions + Ukraine war → 40-year high inflation (2021-23). Central banks (Fed, ECB, RBI) raised rates aggressively.
• Debt Crisis: Rising global debt-to-GDP. Sri Lanka (2022 default), Pakistan (IMF bailouts), Zambia, Ghana. Risk: Sovereign defaults.
• Trade Wars: US-China tariffs (2018 onwards). Technology decoupling. Export controls on semiconductors. Supply chain restructuring (China +1 strategy).
• Climate Change: Physical risks (extreme weather → supply shocks). Transition risks (carbon taxes → stranded assets). Carbon border adjustment (EU CBAM).
• De-globalization: Friendshoring, reshoring, supply chain localization. Post-COVID and Ukraine war exposed supply chain vulnerabilities.

Economic Concepts for Business:

Break-even Analysis:

• Fixed Costs (FC) + Variable Costs (VC). TC = FC + VC.
• Revenue = P × Q. Break-even when Revenue = TC → Q* = FC/(P-VC). Contribution margin = P - VC.
• Margin of Safety = Actual Sales - Break-even Sales.

Pricing Strategies:

• Cost-plus pricing: MC + margin.
• Penetration pricing: Low initial price to gain market share (loss leader).
• Skimming: High initial price (new technology, luxury).
• Price discrimination: Segmented markets.
• Dynamic pricing: Surge pricing (Uber, airlines, hotels).

Investment Appraisal:

• NPV (Net Present Value): PV of cash inflows - PV of cash outflows. If NPV > 0, accept project. TVM: Money today > Money tomorrow.
• IRR (Internal Rate of Return): Discount rate where NPV = 0. If IRR > cost of capital, accept.
• Payback Period: Time to recover initial investment. Simple, ignores TVM.
• ROI (Return on Investment): Net profit / Investment × 100.

Working Capital Management:

• Current Ratio (CR): Current Assets / Current Liabilities. >1.5 good.
• Quick Ratio (Acid Test): (Current Assets - Inventory) / Current Liabilities. >1 good.
• Inventory turnover, receivables turnover, payables turnover.
• Cash conversion cycle: Days Inventory Outstanding + Days Sales Outstanding - Days Payable Outstanding.

Capital Structure:

• MM Theorem (Modigliani-Miller): Without taxes, firm value independent of capital structure (irrelevant). With taxes, debt is beneficial (interest tax shield) → 100% debt is optimal.
• In practice: Pecking order theory (internal funds > debt > equity). Trade-off theory (debt benefits vs financial distress costs).
• WACC: Weighted average cost of capital = E/V × Ke + D/V × Kd × (1-t). Minimizing WACC maximizes firm value.

Derivatives & Risk:

• Forward/Futures: Agree to buy/sell at future date, pre-agreed price. Exchange-traded (futures) vs OTC (forwards).
• Options: Right but not obligation. Call (buy) vs Put (sell). American vs European. Premium paid upfront.
• Hedging: Use derivatives to reduce existing risk. Airline hedging jet fuel costs. Importer hedging forex risk.
• Speculation: Taking risk for profit. Contrarian.

⚡ XAT Final Strategy:

• Read Economic Survey of India (annual) — provides comprehensive economic overview, policy directions.
• Follow RBI’s Monetary Policy Report (biannual).
• Read business newspapers (The Economist, Financial Express, Business Standard) — not just static facts.
• Practice case-based questions involving break-even, market structures, cost analysis.
• Understand government schemes: PM-KISAN, PM Awas Yojana, Ayushman Bharat, Startup India, Make in India — their objectives and impact.
• Note economic terms from business news:stagflation, supply chain disruption, greenwashing, ESG investing, circular economy.
