Economics (PGT) — Study Notes for HTET Level 3
Overview
Economics at the PGT level for HTET covers a comprehensive range of topics spanning microeconomics, macroeconomics, Indian economy, and development economics. This subject tests both theoretical understanding and the ability to apply economic concepts to real-world scenarios, particularly in the Indian context.
For HTET PGT, candidates must demonstrate mastery over NCERT Class XI and XII economics content along with deeper conceptual clarity expected of a senior secondary teacher. Questions typically test understanding of economic theories, policies, statistical concepts, and current economic developments in India. The ability to explain complex economic phenomena in simple terms—a pedagogical necessity—is implicitly assessed.
Approximately 60-70% of questions come from core microeconomic and macroeconomic theory, while 30-40% focus on Indian economy and development issues. Strong command over graphs, numerical problems, and policy-related questions is essential.

Key Concepts
• **Scarcity and Choice**: Economics studies how societies allocate scarce resources among unlimited wants—the fundamental economic problem that drives all economic analysis.
• **Law of Demand and Supply**: Demand curves slope downward (inverse price-quantity relationship); supply curves slope upward (direct relationship). Market equilibrium occurs where demand equals supply.
• **Elasticity**: Measures responsiveness—price elasticity of demand (Ed = % change in Qd ÷ % change in P). Elastic if Ed > 1, inelastic if Ed < 1, unitary if Ed = 1.
• **National Income Accounting**: GDP = C + I + G + (X - M). Distinction between GDP at market price, GDP at factor cost, GNP, NNP, and per capita income is crucial.
• **Money and Banking**: Functions of money (medium of exchange, store of value, unit of account), money supply measures (M1, M2, M3), credit creation by commercial banks (Credit = Initial Deposit × 1/CRR).
• **Inflation and Unemployment**: Inflation types (demand-pull, cost-push), Phillips Curve relationship, stagflation. Unemployment types—frictional, structural, cyclical, disguised.
• **Indian Planning and Reforms**: Five-Year Plans (1951-2017), 1991 LPG reforms (Liberalisation, Privatisation, Globalisation), NITI Aayog replacing Planning Commission (2015).
• **Human Development**: HDI components—health (life expectancy), education (mean and expected years of schooling), and standard of living (GNI per capita). India's HDI rank and challenges.

Formulas / Key Facts
**Microeconomics Formulas:**
- Total Revenue (TR) = Price × Quantity
- Marginal Revenue (MR) = Change in TR ÷ Change in Q
- Average Cost (AC) = Total Cost ÷ Quantity
- Profit Maximisation: MR = MC
