1. National Income and Related Aggregates

Basic macroeconomic concepts · Circular flow and measuring national income · National income aggregates

• Basic Macroeconomic Concepts: Goods, Stocks, Flows and Investment – Macroeconomics looks at the whole economy. Before we measure national income we need a few words. Final goods are bought for final use; intermediate goods are used up by firms in making other goods in the same year. Final goods are consumption goods (used up by families) or capital goods (used again and again to produce). A stock is measured at a point of time; a flow over a period. Gross investment is all new capital; depreciation is normal wear and tear; net investment = gross investment − depreciation.
• Circular Flow of Income and the Three Methods of Measuring National Income – In a two-sector economy households give factor services to firms and get factor payments (rent, wages, interest, profit); they spend this income on the firms' goods. Money moves in a circle opposite to the real flow of goods and services. Because the same money passes three points, national income can be measured three ways: value added by producers (product method), incomes paid to factors (income method) and spending on final goods (expenditure method). All three give the same total.
• National Income Aggregates: GDP, GNP, NDP, NNP, Real GDP and Welfare – Start with GDP at market price: value of all final goods and services made inside the country in a year. Subtract depreciation to go from Gross to Net. Add net factor income from abroad (NFIA) to go from Domestic to National. Subtract net indirect taxes (indirect taxes − subsidies) to go from Market Price to Factor Cost. NNP at factor cost is National Income. Nominal GDP uses current prices; real GDP uses base-year prices; GDP deflator = nominal ÷ real × 100. A higher GDP need not mean more welfare because of unequal distribution, non-monetary exchanges and externalities.

2. Money and Banking

Money and its supply · Money creation and central bank

• Money and Its Supply: Barter, Functions of Money and M1 – Barter (goods for goods) needs a double coincidence of wants and has no common measure of value. Money solves this. Its functions: medium of exchange (main), unit of account, store of value and standard of deferred payment. Money supply is the total stock of money held by the public (households and firms) at a point of time. Notes are issued by the RBI and coins by the government; demand deposits are created by commercial banks. Narrow money M1 = currency with the public (CU) + net demand deposits in banks (DD) + other deposits with the RBI (OD).
• Money Creation by Banks and the Central Bank (RBI) – Banks keep only a part of deposits as reserves (the legal reserve ratio, LRR) and lend the rest. Each loan is spent and comes back to banks as a new deposit, so total deposits become a multiple of the first deposit: total deposits = initial deposit × 1/LRR. The RBI is India's central bank: it issues currency, is banker to the government and to banks, is lender of last resort, controls credit and keeps foreign exchange reserves. It controls credit with repo rate, reverse repo rate, bank rate, CRR, SLR, open market operations and margin requirements.

3. Determination of Income and Employment

Aggregate demand and multiplier · Full employment, excess and deficient demand

• Aggregate Demand, Propensities to Consume and Save, and the Investment Multiplier – Aggregate demand (AD) is total planned spending on final goods: C + I + G + (X − M); in a two-sector model AD = C + I. Consumption depends on income: C = c̄ + bY, where b = MPC. APC = C/Y, MPC = ΔC/ΔY, APS = S/Y, MPS = ΔS/ΔY; APC + APS = 1 and MPC + MPS = 1. Short-run equilibrium output is where AD = AS (planned spending = output), or saving = planned investment. A rise in investment raises income by a multiple: k = ΔY/ΔI = 1/(1 − MPC) = 1/MPS.
• Full Employment, Excess Demand and Deficient Demand – Full employment means everyone able and willing to work at the current wage has a job. Involuntary unemployment means people willing to work at the current wage cannot find work. Deficient demand: AD at full-employment output is less than that output; the shortfall is the deflationary gap, causing lower output, unemployment and falling prices. Excess demand: AD at full employment is more than full-employment output; the excess is the inflationary gap, causing rising prices without more output. Both are corrected by fiscal policy (government spending, taxes) and monetary policy (RBI tools that change money supply).

4. Government Budget and the Economy

Government budget

• Government Budget and the Economy – A government budget is a yearly plan of expected receipts and planned expenditure. Receipts are revenue (taxes, non-tax income) or capital (borrowing, loan recovery, disinvestment). Spending is revenue (builds no asset) or capital (builds an asset or cuts debt). A budget can be balanced, surplus or deficit, and the deficit is measured as revenue, fiscal and primary deficit.

5. Balance of Payments

Balance of payments · Foreign exchange rate

• Balance of Payments – The balance of payments (BoP) is a yearly record of all money dealings between residents of a country and the rest of the world. The current account records goods, services, transfers and income; the capital account records investment, loans and deposits. Autonomous items are done for their own sake; accommodating items (reserve changes) settle the gap. A BoP surplus raises reserves; a deficit lowers them.
• Foreign Exchange Rate – The foreign exchange rate is the price of one currency in terms of another, such as ₹80 per dollar. Under a flexible rate, demand for and supply of foreign currency set it; a rise means the rupee depreciates. Under a fixed rate, the government sets it and changes it by devaluation or revaluation. Managed floating mixes both: the market sets the rate, and the central bank smooths big swings.

6. Development Experience (1947-90) and Economic Reforms since 1991

Indian economy on the eve of independence · Planning and policies 1950-90 · Reforms since 1991

• Indian Economy on the Eve of Independence – When India became independent in 1947, about two centuries of colonial rule had left a poor, stagnant economy. Most people farmed, but yields were low under the zamindari system. Handicrafts had collapsed and modern industry was small. Foreign trade served Britain, and the export surplus drained away. Literacy and life expectancy were low; railways and ports existed mainly for colonial needs.
• Indian Economy 1950–1990: Planning and Policies – After 1947 India chose a mixed economy guided by five-year plans. The plans aimed at growth, modernisation, self-reliance and equity. In agriculture, land reforms and the Green Revolution raised food output. In industry, the Industrial Policy Resolution 1956 gave the public sector the lead, with licensing and protection for small-scale industry. Trade followed import substitution behind tariffs and quotas.
• Politics of Planned Development – After independence India debated how to develop: the market road or the state-led road. It chose a mixed economy and set up the Planning Commission in 1950. The First Five Year Plan focused on agriculture and irrigation; the Second Plan, led by P.C. Mahalanobis, pushed heavy industry through the public sector. People argued about agriculture versus industry and public versus private. The results were a base of industry, partly successful land reforms, the Green Revolution and new political voices of farmers.
• Economic Reforms Since 1991: LPG, Demonetisation and GST – In 1991 India faced a balance of payments crisis, with forex reserves enough for about two weeks of imports. It took IMF and World Bank loans and launched the New Economic Policy of liberalisation, privatisation and globalisation (LPG). Growth, reserves and services rose, but agriculture, jobs and small firms faced strain. Demonetisation (2016) cancelled old ₹500 and ₹1000 notes, and GST (2017) replaced many indirect taxes with one tax.

7. Current Challenges facing Indian Economy

Human capital formation · Rural development · Employment · Sustainable economic development

• Human Capital Formation in India – Human capital is the skill, knowledge and good health stored in people. When a country spends on education, health, training, migration and information, people become more productive. This is human capital formation. It raises output, spreads new ideas and improves quality of life, so it is both a cause and a result of development. India has grown its schools, colleges and literacy a lot since 1951, but spending on education is still below the 6% of GDP goal.
• Rural Development in India – Rural development means raising the living standard of village people: better credit, fair markets, roads and power, schools and health, more kinds of jobs and care for land. Farmers need cheap credit from banks, NABARD, cooperatives and self-help groups instead of moneylenders. Regulated markets, storage and cooperatives help them get fair prices. Diversification into dairy, fishing, horticulture and non-farm work gives more income. Organic farming keeps soil and food safe.
• Employment: Growth, Informalisation and Other Issues – A worker is anyone doing a job that adds to national output, even if self-employed. The share of people who work is the worker-population ratio. In India about half the workers are self-employed; the rest are regular salaried or casual wage workers. Most jobs are in the informal sector, with no job security or social security. Problems include unemployment (open, disguised, seasonal), jobless growth and casualisation. Government tries to fix them through direct job schemes like MGNREGA and indirect help through growth, skills and credit.
• Environment and Sustainable Development – The environment gives us resources, soaks up our waste, supports life and gives beauty. When we take resources faster than nature renews them, or throw waste faster than it can absorb, we cross its carrying capacity and face an environmental crisis. India faces land degradation, air and water pollution, forest and biodiversity loss. Burning fossil fuels traps heat and causes global warming; CFCs thin the ozone layer. Sustainable development meets today's needs without harming the ability of future generations to meet theirs, using clean energy, less waste and traditional knowledge.

8. Development Experience of India: A Comparison with Neighbours

Comparing India, Pakistan and China

• Development Experience of India: A Comparison with Neighbours – India, Pakistan and China began their development journeys at about the same time (1947–49) with similar poverty. China reformed first (1978), Pakistan in 1988 and India in 1991. China grew fastest, near 10% a year for decades, led by industry. India grew steadily, led by services. Pakistan's growth was slower and uneven. China controlled population with the one-child policy; India now has the largest population. China is far ahead on human development indicators such as life expectancy, literacy and infant mortality; India is in the middle and Pakistan lags.
