SECTION I – Understanding Economics

Chapter 1 : Definition of Economics

• Evolution of economic thought
  • Wealth definition – Adam Smith: Economics studies the “nature and causes of the wealth of nations.”
  • Significance: Focus on production & accumulation; criticised for materialistic bias.
  • Welfare definition – Alfred Marshall: Emphasises human welfare over mere wealth.
  • Scarcity definition – Lionel Robbins: Economics is the science of choice under scarcity; centrality of opportunity cost.
  • Growth-oriented definition – Paul Samuelson: Dynamic view, combining scarcity with growth & choice over time.
• Subject matter
  • Microeconomics: Individual units, price determination, consumer & producer behaviour.
  • Macroeconomics: Aggregates—national income, employment, inflation.
  • Their differences & interdependence (e.g., micro foundations of macro models).
• Illustrative economic questions (from text)
  • Individual choices of consumption & saving; pricing & wage determination; policy issues—privatisation, BOP deficits, recession 2008-10.

Chapter 2 : Basic Concepts of Economics

• Human wants
  • Classification: Necessaries, comforts, luxuries
  • Features: Unlimited, gradable, competitive, satiable individually but not collectively.
• Consumption & Sustainable Consumption
  • Significance: Utility maximisation balanced with resource conservation.
• Utility
  • Total vs. Marginal Utility; law of diminishing marginal utility; ethical debate on consumerism.
• Production & Factors of Production
  • Land, labour, capital, entrepreneurship – characteristics, mobility, remuneration (rent, wages, interest, profit).
• Price & General Price Level — links to inflation expectations.
• Inflation
  • Demand-pull vs. cost-push; policy trade-offs (Phillips curve conceptually connected).
• Market types – Perfect competition, monopoly, monopolistic competition, oligopoly.
• Income (personal, national) & Per-Capita Income
• Saving & Investment – Classical vs. Keynesian view on equality; accelerator principle.
• Stock vs. Flow variables – Wealth (stock) vs. income (flow).

Chapter 3 : Basic Problems of an Economy

• Scarcity → choice → central problems: What, how, for whom to produce; efficient use of resources.
• Production Possibility Curve (PPC)
  • Assumptions: Fixed resources & technology, full employment.
  • Characteristics: Downward-sloping, concave due to increasing opportunity cost.
  • Shifts reflect growth; points inside = unemployment/inefficiency.

Chapter 4 : Types of Economies

• Developed vs. Developing – UN, World Bank income thresholds; structural characteristics (e.g., sectoral share of GDP).
• Economic Systems
  • Capitalism: Private ownership, price mechanism; merits (efficiency), demerits (inequality, market failure).
  • Socialism: State ownership, planning; merits (equity), demerits (bureaucracy).
  • Mixed economy: Co-existence; India’s ‘commanding heights’ model until 1991.
  • Other binaries: Simple/complex, closed/open, agricultural/industrial.
• Regional & global groupings – EU, ASEAN, BRICS, SAARC.

Chapter 5 : Solutions to Basic Problems under Different Systems

• Price mechanism in capitalism—guides allocation via $P = MC$ equilibrium.
• Planning in socialism—central authority sets output targets.
• Mixed economies blend the two; public-private partnership (e.g., Indian electricity sector).
• Limitations: Externalities, information asymmetry, policy lags.

SECTION II – Indian Economic Development

Chapter 6 : Economic Growth and Development

• Distinction: Growth = quantitative $\Delta Y$; Development = qualitative (HDI, equity).
• Sustainable development integrates environment (Brundtland definition).

Chapter 7 : Indicators of Development

• Quality-of-Life Index – includes life expectancy, literacy.
• Human Development Index (HDI)
  • Construction: Life expectancy, education index, GNI per capita (log scale).
  • India’s rank & state disparities.

Chapter 8 : Sustainable Development

• Resource depletion channels: deforestation, groundwater overuse.
• Strategies: Renewable energy, green taxes, PPP in waste management.

Chapter 9 : Planning & Economic Development in India

• Five-Year Plans (1951-2017): Mahalanobis model, sectoral priorities, achievements (literacy up, life expectancy), failures (jobless growth).
• NITI Aayog – Think-tank functions, cooperative federalism.

Chapter 10 : Indian Economy Post-Liberalisation

• 1991 crisis → New Economic Policy: Liberalisation, Privatisation, Globalisation (LPG).
• Agricultural reforms: MSP rationalisation, crop diversification.
• Industrial reforms: De-licensing, FDI caps raised.
• Foreign trade: Shift from inward-looking to export promotion; WTO commitments.

Chapter 11 : Structural Changes after Liberalisation

• Liberalisation
  • Deregulation, interest-rate reforms, SEZ policy.
• Privatisation
  • Disinvestment, strategic sale vs. minority sale, PPP models.
• Globalisation
  • Trade-to-GDP ratio rise, service-exports boom; concerns—de-industrialisation, income volatility.

Chapter 12 : Poverty in India

• Absolute vs. Relative poverty; Tendulkar vs. Rangarajan committees.
• Vicious circle: Low income → low saving → low investment.
• Flagship schemes: PDS, PM-KISAN, DBT, MGNREGA.
• Critical appraisal: Inclusion errors, fiscal burden, need for universal basic income.

Chapter 13 : Indian Agriculture & Rural Development

• Agriculture’s share in employment > 40 %; declining GDP share.
• Agricultural marketing defects – long chain of intermediaries, inadequate cold storage.

SECTION III – Statistics for Economics

Chapter 16 : Statistics – Definition, Scope & Limitations

• Plural sense: Numerical facts; Singular sense: Science of data.
• Limitations: Only aggregates, may mislead without context, ethical use crucial (data privacy).

Chapter 17 : Collection, Organisation & Presentation of Data

• Primary vs. Secondary data; census vs. sample surveys.
• Data classification: Geographical, chronological, qualitative, quantitative.
• Frequency distributions; tabulation & diagrammatic presentation (bar, pie, histogram).

Chapter 18 : Measures of Central Tendency

• Arithmetic Mean $\bar{X} = \frac{\sum X}{N}$
• Median (middle value); graphical derivation via ogive.
• Mode – most frequent; relation $3\,\text{Median} = 2\,\bar{X} + \text{Mode}$.
• Choice of average depends on data skew, purpose, simplicity.

Chapter 19 : Measures of Dispersion

• Range $= X<em>{\max} - X</em>{\min}$
• Quartile Deviation $= \frac{Q<em>3 - Q</em>1}{2}$
• Mean Deviation $
  $MD = \frac{\sum |X - A|}{N}$
• Standard Deviation
  $\sigma = \sqrt{\frac{\sum (X-\bar{X})^2}{N}}$
• Coefficient of Variation $CV = \frac{\sigma}{\bar{X}} \times 100$ – basis for comparing stability.
• Lorenz Curve – visual inequality measure; area between curve & line of equality linked to Gini coefficient.

Chapter 20 : Correlation
