1. Economic skills, scarcity and exchange
Economic skills and strategic insight · Scarcity and choice · Exchange, specialisation and money
- Economics Basics: How People, Firms and the State Choose – Economics is the science of how people, firms and governments use limited resources to meet unlimited wants. Needs are met by goods and services (free vs economic goods, consumer vs capital goods, private vs public goods). Because of scarcity, every society answers What, How and For whom to produce. Three economic agents act: households (work, consume, save), firms (produce and sell to earn profit = revenue − cost) and the state (rules, taxes, public services). Economics uses methods like observation, models and statistics; it splits into microeconomics (one household, firm, market) and macroeconomics (whole economy: GDP, unemployment, inflation, cycles). Social goals include growth, full employment, stable prices, fair income sharing and sustainability.
- The Problem of Choice: Scarcity and Opportunity Cost – Our wants are unlimited but resources like money, time, land and workers are limited. This is scarcity, and it forces us to choose. The value of the next best option we give up is the opportunity cost. Economists study how people and societies make these choices. Every society must decide what, how and for whom to produce. Market, planned and mixed economies answer these differently, and a welfare state makes sure basic needs of all are met.
- International Trade: Comparative Advantage, Protection and the Forex Market – Countries gain by specialising in goods where their opportunity cost is lowest (comparative advantage) and trading at terms between their costs. Tariffs, quotas and subsidies protect local firms but raise prices and cause a deadweight loss. Trade blocs and the WTO shape the rules. In the foreign exchange market, a rise in a country's real interest rate pulls in capital, raises demand for its currency, makes it appreciate and lowers net exports.
2. Market
Market demand and supply · Market mechanism and market forms · Costs, revenue and producer behaviour · Consumer behaviour · Market failure, government and welfare · Labour market
- Demand, Supply and Market Equilibrium – The law of demand says buyers want less when the price rises; the law of supply says sellers offer more. The market price settles at equilibrium, where quantity demanded equals quantity supplied, and shifts in demand or supply move it. Some goods break the usual laws (Giffen, Veblen, panic buying). A price ceiling set below equilibrium causes shortages. Markets can also fail, for example with pollution or public goods like street lights, so the government steps in.
- Market Structures: From Perfect Competition to Monopoly – A market structure describes how many firms sell, how alike their products are, and how easy it is to enter. Perfect competition: many firms, identical goods, free entry, price takers, normal profit in the long run. Monopolistic competition: many firms, differentiated goods, easy entry, some price power. Oligopoly: a few interdependent firms, high barriers, strategic behaviour (game theory, collusion, price leadership). Monopoly: one firm, no close substitutes, high barriers, price maker with possible supernormal profit and price discrimination. Contestable markets show that the threat of entry also limits power.
- Cost and Revenue: TC, AC, MC and TR, AR, MR – Cost is what a firm spends on inputs. Total cost (TC) = total fixed cost (TFC) + total variable cost (TVC). Dividing by output gives AFC, AVC and AC; marginal cost (MC) is the extra cost of one more unit. AFC keeps falling; AVC, AC and MC are U-shaped, and MC cuts AVC and AC at their minimum. Revenue is money from sales: TR = P × q, AR = TR/q = price, MR = extra TR from one more unit. With a fixed price AR = MR; with a falling price MR lies below AR and TR is highest where MR = 0.
- Demand and Price Elasticity of Demand – Demand is the quantity of a good buyers are willing and able to buy at each price in a period. Market demand adds up all buyers' demand at each price. Demand depends on own price, income, prices of related goods, tastes, expectations and number of buyers. A change in own price moves us along the curve; a change in any other factor shifts it. Price elasticity of demand (Ed) = % change in quantity ÷ % change in price; it can also be judged from total expenditure.
- 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.
- The Labour Market – The labour market is where workers sell their time and skills and employers buy them. Firms demand labour because people buy their products (derived demand). Workers supply labour, and more people offer work at higher wages. The wage settles where demand meets supply. A minimum wage above that level can raise pay but may cut jobs. Trade unions, a single big employer (monopsony), skills, discrimination and new technology all change wages and jobs.
3. Exchange over time
Households exchange over time · Government exchanges over time · Pensions
- Smart Ways to Manage Your Finances – Inflation makes prices rise, so the same money buys less. Money kept in a bank earns interest: simple interest is paid only on the original amount, while compound interest also earns interest on earlier interest, so it grows faster over time. A budget plans income into needs, wants and savings. Savings are kept safe; investments can grow but carry risk, and higher possible returns mean higher risk. Insurance shares risk among many people. Income tax is paid on income above a limit, at rates that rise with income.
- 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.
- Pensions: Money for When You Stop Working – A pension is an income you get after you retire. In a pay-as-you-go (PAYG) system, today's workers pay for today's retirees. In a funded system, each person saves into a pot that is invested and grows with compound interest. Most countries mix three pillars: a state pension, a workplace pension and private savings. Because people live longer and have fewer children, there are fewer workers per retiree, which puts pressure on PAYG systems and on public debt. Starting to save early is the strongest single lever.
4. Research, experiments and electives
Research and economic experiments · Elective topics (at least two)
- Research Skills: From a Question to a Finished Project – Research is a careful way of finding an answer. You ask a clear, focused question, plan how to answer it, find information and check that each source can be trusted, collect and analyse your own data, draw a conclusion that the evidence supports, and share it while crediting every source you used.
- Economics Basics: How People, Firms and the State Choose – Economics is the science of how people, firms and governments use limited resources to meet unlimited wants. Needs are met by goods and services (free vs economic goods, consumer vs capital goods, private vs public goods). Because of scarcity, every society answers What, How and For whom to produce. Three economic agents act: households (work, consume, save), firms (produce and sell to earn profit = revenue − cost) and the state (rules, taxes, public services).
