National Year 11 Economics

Chapters: 5

1. 3.2.1 Introduction to the national economy

3.2.1.1 Interest rates, saving, borrowing and investment · 3.2.1.2 Government income and spending

Interest Rates: Saving, Borrowing and Investment – An interest rate is the price of borrowing money, written as a percentage per year. Savers earn interest as a reward for waiting and for taking a risk; borrowers pay it. Rates depend on the central bank's base rate, on risk, on time and on collateral. Higher rates encourage saving and discourage borrowing, spending and investment.
Taxation: Types of Taxes and How to Calculate Them – A tax is money people and businesses must pay to the government. The government uses it for public goods (roads, schools, hospitals, defence), to help poorer people and to manage the economy. Direct taxes are paid straight from income or wealth (income tax, corporate tax, property tax). Indirect taxes are added to the price of goods and services (GST, VAT, excise, customs). A tax is progressive if richer people pay a bigger share of income, proportional (flat) if all pay the same share, and regressive if poorer people pay a bigger share. Income tax often uses slabs: each slab of income has its own rate. Effective rate = total tax ÷ income × 100.

2. 3.2.2 Government objectives

3.2.2.1 Economic objectives and conflicts · 3.2.2.2 Economic growth · 3.2.2.3 Employment and unemployment · 3.2.2.4 Inflation · 3.2.2.5 Balance of payments · 3.2.2.6 Distribution of income

Macroeconomic Objectives and Policy Conflicts – Governments want four main things for the whole economy: steady growth of real GDP, low unemployment, stable prices (low inflation, often about 2%) and a sustainable balance of trade. Many also aim for a fairer spread of income and a protected environment. These goals often clash: a policy that helps one can hurt another, so governments must choose trade-offs.
Economic Growth: How a Country Makes More Each Year – Economic growth is a rise in a country's real GDP: the value of all final goods and services it makes in a year, after removing the effect of price rises. The growth rate is the percentage change in real GDP. GDP per head tells us the average output per person. Growth goes up and down around a trend in the economic cycle, creating output gaps. Growth comes from more and better resources (workers, skills, machines, technology) and brings higher incomes and jobs, but can also cause pollution, inequality and inflation.
Unemployment: Meaning, Rate, Types, Costs and Cures – A person is unemployed when they have no job, are able to work, and are actively looking for work. The labour force is everyone who is employed plus everyone who is unemployed. The unemployment rate is the unemployed divided by the labour force, times 100. Economists sort unemployment by its cause: frictional (moving between jobs), structural (skills or places no longer match the jobs), cyclical (a slump in total demand) and seasonal (work only in some months). Unemployment costs the person income, costs the country lost output and tax, and can harm health and society. Governments fight it with spending and interest-rate policy for cyclical unemployment and with training, information and mobility for the other types. Some unemployment always remains; the lowest sustainable level is called the natural rate.
Inflation: Why Prices Keep Rising – Inflation is a general, continuing rise in the price level, which lowers the purchasing power of money. It is measured with a price index such as the CPI: inflation rate = (new index − old index) ÷ old index × 100. Causes: demand-pull (demand grows faster than output), cost-push (costs rise) and expectations. Effects hit savers, fixed incomes and competitiveness. Deflation is a falling price level. Central banks aim for low, stable inflation, often about 2%, using interest rates; governments also use fiscal and supply-side policies.
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.
Income Inequality – Income inequality means income is shared unevenly between people. Economists rank people from poorest to richest, split them into five groups of 20% (quintiles) and compare their shares. The Lorenz curve plots the cumulative share of income against the cumulative share of people; the further it bends from the straight line of equality, the more unequal the society. The Gini coefficient = A ÷ (A + B) turns this into one number between 0 (perfect equality) and 1 (one person has everything). Wealth (what you own) is usually more unequal than income (what you earn). Causes include differences in skills, education, inherited wealth, discrimination and technology. Governments reduce inequality with progressive taxes, benefits, minimum wages and public services such as free schooling and health care.

3. 3.2.3 How the government manages the economy

3.2.3.1 Fiscal policy · 3.2.3.2 Monetary policy · 3.2.3.3 Supply-side policies · 3.2.3.4 Correcting externalities

Fiscal Policy – Fiscal policy is how a government uses its spending (G) and taxes (T) to steer the whole economy. The budget compares the two: if spending is bigger than tax revenue the budget is in deficit and the government borrows; if tax is bigger, it is in surplus. In a slump the government can use expansionary policy (spend more or cut taxes) to raise total demand, output and jobs. When demand is too strong and inflation is high it can use contractionary policy (spend less or raise taxes). Because money is re-spent, a change in G has a bigger final effect on demand: the multiplier. Some changes happen by themselves (automatic stabilisers, such as falling tax receipts and rising benefits in a recession); others are chosen (discretionary). Fiscal policy has limits: time lags, rising public debt, higher interest rates (crowding out) and political pressure. It works alongside monetary policy, which is run by the central bank through interest rates.
Monetary Policy – Monetary policy is the use of interest rates and the money supply by a central bank to keep prices stable and support growth and jobs. Raising the policy rate makes borrowing dearer, cuts spending and aggregate demand, and lowers inflation (contractionary). Cutting it does the opposite (expansionary). Other tools include open market operations, quantitative easing, reserve requirements and forward guidance. Most central banks follow an inflation target and are independent of the government. Monetary policy works with time lags and is weaker when rates are already near zero.
Supply-Side Policies – Supply-side policies try to raise how much an economy CAN produce (its productive capacity), not just how much people want to buy. They aim to make workers more skilled, markets work better and firms invest more. Market-based policies give people and firms more reason to work and compete: cutting income and profit taxes, removing unneeded rules (deregulation), selling state firms (privatisation) and reforming trade unions. Interventionist policies use government spending: education and training, roads and ports, broadband and research. If they work, the long-run aggregate supply (LRAS) curve shifts right: output and jobs can grow without pushing up prices, and exports become more competitive. But they are slow, can be costly, and some may increase inequality.
Market Failure – A market fails when buying and selling on its own does not give the best result for society. Resources are used in the wrong amounts: too much of some goods (pollution, cigarettes), too little of others (street lights, vaccines, education). Main causes: externalities, public goods, merit and demerit goods, imperfect information, market power and unfair inequality. Governments try to fix it with taxes, subsidies, rules, direct provision and information, but government action can also fail.

4. 3.2.4 International trade and the global economy

3.2.4.1 Why countries trade · 3.2.4.2 Exchange rates · 3.2.4.3 Free-trade agreements · 3.2.4.4 Globalisation

International Trade: Basis, Balance, WTO and Ports – International trade is the exchange of goods and services between countries. It began with barter, grew along routes like the Silk Route, passed through the cruel slave trade and colonial trade, and expanded with industry. Countries trade because they differ in resources, population, development, foreign investment and transport. Balance of trade compares exports and imports. Trade can be bilateral or multilateral; free trade lowers barriers, while dumping sells goods abroad below cost. The WTO sets global rules, regional blocs group neighbours, and ports of many types act as gateways.
Exchange Rates: Converting Money Between Currencies – A currency is the money used in a country or group of countries. An exchange rate is the price of one currency in terms of another, for example 1 USD = 83 INR. To convert into the second currency, multiply by the rate; to convert back, divide. Banks and money changers sell foreign currency at a higher rate and buy it at a lower rate, and may charge commission, so each swap costs you a little. Rates change with demand and supply. When a currency appreciates it buys more foreign money: imports get cheaper and exports dearer. When it depreciates, the opposite happens. People and firms gain or lose when rates move between buying and selling.
Globalisation and the Indian Economy – Globalisation is the fast joining of countries' economies through trade, investment, technology and movement of people. MNCs spread production across countries. New technology and liberalisation (removing trade barriers, in India from 1991) made it possible. The WTO sets trade rules. Globalisation helped some groups and hurt others, so we need fair globalisation.

5. 3.2.5 Money and financial markets

3.2.5.1 The role of money · 3.2.5.2 The financial sector

Money and Credit – Money is a medium of exchange that removes the need for a double coincidence of wants. Banks take deposits and give loans. Credit can help people grow, or trap them in debt, depending on its terms. Formal loans from banks and cooperatives are cheaper and regulated; informal loans from moneylenders are costly. Self-Help Groups bring cheap credit to poor women.
The Financial Sector: Banks, Insurers and Markets – The financial sector is all the firms that deal with money: banks, building societies and credit unions, insurance companies, and financial markets such as the stock market and bond market. Its main job is to link savers, who have spare money, with borrowers, who need money. Banks take deposits, pay interest and lend at a higher interest rate. Insurers collect small premiums from many people and pay out to the few who suffer a loss, so risk is shared. Financial markets let firms and governments raise money by selling shares and bonds, and let investors buy and sell them. The sector also runs payments (cards, transfers, UPI) and currency exchange. It matters because it turns savings into investment that builds factories, homes and jobs. When it fails, as in the 2008 crisis, the whole economy suffers.
