Two Books Covered in CBSE Class 12 Economics Notes

Class 12 Microeconomics Chapter Wise Revision Notes

Book 1: Introductory Macroeconomics Revision Notes

Introductory Macroeconomics studies the economy as a whole. It examines total output, employment, money supply, government finance and transactions with other countries.

Chapter 1: Introduction

Macroeconomics studies aggregate economic variables such as total output, employment, general price level and national income.

It developed as a separate area of study after economists recognised that the behaviour of an entire economy could not always be explained through individual consumers and firms.

Important participants in an economy include:

• Households
• Firms
• Government
• External sector

Households supply factors of production and consume goods and services. Firms produce goods and employ factors of production.

The government collects taxes, spends on public services and regulates economic activity. The external sector connects the domestic economy with other countries.

Chapter 2: National Income Accounting

National income accounting measures the value of final goods and services produced during an accounting year.

Important concepts include:

• Final goods and intermediate goods
• Consumer goods and capital goods
• Stocks and flows
• Depreciation
• Gross investment and net investment
• Domestic territory
• Normal residents

The three methods of calculating national income are:

1. Value added method
2. Income method
3. Expenditure method

Under the expenditure method:

GDP at market price = C + I + G + (X − M)

Here:

• C = Private consumption expenditure
• I = Investment expenditure
• G = Government expenditure
• X = Exports
• M = Imports

Important relationships include:

NDP = GDP − Depreciation

GNP = GDP + Net Factor Income from Abroad

NNP = GNP − Depreciation

Nominal GDP measures production at current prices. Real GDP measures production at constant prices.

GDP Deflator = Nominal GDP/Real GDP × 100

GDP is an important indicator of output, but it does not fully measure welfare. It may ignore income inequality, environmental damage and unpaid household work.

Chapter 3: Money and Banking

Money is anything generally accepted as a medium of exchange.

Its main functions are:

• Medium of exchange
• Measure of value
• Store of value
• Standard of deferred payment

Money supply includes currency held by the public and demand deposits held with commercial banks.

Commercial banks:

• Accept deposits
• Provide loans
• Transfer funds
• Create credit

Banks keep a part of deposits as reserves and lend the remaining amount. This process leads to credit creation.

Money Multiplier = 1/Legal Reserve Ratio

The Reserve Bank of India controls money and credit through monetary policy.

Important tools include:

• Repo rate
• Reverse repo rate
• Bank rate
• Cash Reserve Ratio
• Statutory Liquidity Ratio
• Open market operations
• Margin requirements

An increase in reserve ratios generally reduces the capacity of commercial banks to create credit.

Chapter 4: Determination of Income and Employment

Aggregate demand is the total planned expenditure on goods and services in an economy.

In a two-sector economy:

AD = C + I

The consumption function is:

C = C̄ + cY

Here, C̄ is autonomous consumption, c is the marginal propensity to consume and Y is income.

Important measures include:

APC = C/Y

APS = S/Y

MPC = ΔC/ΔY

MPS = ΔS/ΔY

The following relationships hold:

APC + APS = 1

MPC + MPS = 1

Equilibrium income is determined where aggregate demand equals aggregate supply or planned saving equals planned investment.

The investment multiplier is:

k = 1/(1 − MPC)

It can also be expressed as:

k = 1/MPS

Excess demand exists when aggregate demand is greater than the output available at full employment. It may create inflationary pressure.

Deficient demand exists when aggregate demand is lower than the full-employment level. It may cause unemployment and reduced production.

Chapter 5: Government Budget and the Economy

A government budget is an annual statement of expected government receipts and expenditure.

Its main objectives include:

• Reallocation of resources
• Reduction of economic inequality
• Economic stability
• Management of public enterprises
• Economic growth

Government receipts are classified as revenue receipts and capital receipts.

Revenue receipts do not create liabilities or reduce government assets. Tax revenue and non-tax revenue are examples.

Capital receipts either create liabilities or reduce assets. Borrowings, disinvestment and recovery of loans are examples.

Revenue expenditure is incurred for regular government activities. Capital expenditure creates assets or reduces liabilities.

Important deficit measures are:

Revenue Deficit = Revenue Expenditure − Revenue Receipts

Fiscal Deficit = Total Expenditure − Total Receipts excluding Borrowings

Primary Deficit = Fiscal Deficit − Interest Payments

Chapter 6: Open Economy Macroeconomics

An open economy interacts with other countries through trade and financial transactions.

The balance of payments records all economic transactions between residents of a country and the rest of the world during a period.

Its two main accounts are:

• Current account
• Capital account

The current account records exports and imports of goods and services, income and transfers.

The capital account records transactions that affect foreign assets and liabilities.

The foreign exchange rate is the price of one currency in terms of another.

Under a flexible exchange-rate system, demand and supply determine the rate.

• Appreciation: Market-led increase in currency value
• Depreciation: Market-led fall in currency value
• Revaluation: Official increase under a fixed system
• Devaluation: Official reduction under a fixed system

Managed floating allows market forces to operate with occasional central-bank intervention.

Book 2: Indian Economic Development Revision Notes

Indian Economic Development examines the condition of the Indian economy at independence, planning, reforms and current development issues.

Chapter 1: Indian Economy on the Eve of Independence

At independence, India had an underdeveloped economy shaped by colonial policies.

Major features included:

• Low agricultural productivity
• Limited industrial development
• Poor infrastructure
• High dependence on agriculture
• Low literacy and life expectancy
• Widespread poverty

Agriculture suffered from exploitative land systems and limited irrigation.

Modern industries were few and mainly concentrated in cotton, jute, iron and steel. Foreign trade largely served British economic interests.

Chapter 2: Indian Economy 1950–1990

India adopted economic planning after independence.

The main goals of the Five Year Plans were:

• Growth
• Modernisation
• Self-reliance
• Equity

Agricultural reforms included land reforms, institutional changes and the Green Revolution.

Industrial policy gave an important role to the public sector. Industrial licensing was used to regulate private investment.

Small-scale industries received protection because they generated employment and supported balanced regional development.

Import substitution aimed to reduce dependence on imported goods by encouraging domestic production.

Chapter 3: Liberalisation, Privatisation and Globalisation: An Appraisal

India introduced major economic reforms in 1991 due to a balance of payments crisis and other economic difficulties.

The reform programme is known as LPG:

• Liberalisation: Reduction of government controls and restrictions
• Privatisation: Increased participation of the private sector
• Globalisation: Integration with the world economy

Reforms included industrial deregulation, financial-sector changes, tax reforms and trade-policy changes.

The reforms improved competition and expanded some industries. However, concerns remain about employment, agriculture, inequality and uneven development.

Chapter 4: Human Capital Formation in India

Human capital refers to the knowledge, skills and health embodied in people.

The main sources of human capital formation are:

• Education
• Healthcare
• On-the-job training
• Migration
• Information

Education raises productivity and supports innovation. Health improves a person’s ability to work and learn.

Human capital and human development are related, but they are not identical. Human capital focuses on productive capacity, while human development focuses on overall well-being.

Chapter 5: Rural Development

Rural development aims to improve the economic and social conditions of people living in rural areas.

Important areas include:

• Rural credit
• Agricultural marketing
• Cooperatives
• Diversification
• Organic farming

Rural credit may come from institutional and non-institutional sources. Institutional sources include commercial banks, cooperative banks and regional rural banks.

Diversification reduces dependence on crop farming. It includes dairy, poultry, fisheries, horticulture and other activities.

Organic farming avoids synthetic chemicals and supports environmentally sustainable agricultural practices.

Chapter 6: Employment: Growth, Informalisation and Other Issues

Employment provides income and supports participation in production.

Workers may be:

• Self-employed
• Regular salaried employees
• Casual wage labourers

The workforce is also divided between formal and informal sectors.

Formal-sector employees generally receive regulated wages, job security and social-security benefits. Informal workers often lack these protections.

Important concerns include:

• Unemployment
• Underemployment
• Casualisation
• Informalisation
• Unequal employment opportunities

Worker-population ratio measures the proportion of the population actively engaged in economic activity.

Chapter 7: Environment and Sustainable Development

The environment supplies resources and absorbs waste. Excessive use can reduce its ability to perform these functions.

Major environmental concerns include:

• Air and water pollution
• Global warming
• Deforestation
• Loss of biodiversity
• Land degradation
• Resource depletion

Sustainable development meets present needs without reducing the ability of future generations to meet their needs.

Strategies include:

• Renewable energy
• Cleaner fuels
• Organic farming
• Waste management
• Sustainable resource use
• Pollution control

Chapter 8: Comparative Development Experiences of India and its Neighbours

This chapter compares the development experience of India, China and Pakistan.

The comparison covers:

• Population
• Economic growth
• Sectoral contribution
• Human-development indicators
• Economic reforms

China introduced market-oriented reforms before India and developed a strong manufacturing sector.

India has shown strength in services and democratic institutions. Pakistan has experienced periods of economic growth but also faces structural and political challenges.

Development should be compared through several indicators, including income, education, health, employment and sectoral transformation.
