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
Demand and supply · Market structure · Efficiency and economic policy
- 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.
- 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.
