Complete revision notes for HKDSE Economics, covering both microeconomics and macroeconomics with worked examples, data-response practice, and exam-style problems. Content follows the HKEAA curriculum structure.

The study of choices: Economics is about how people, businesses, and governments make decisions under scarcity. Microeconomics studies individual choices; macroeconomics studies the big picture.

Why it matters: Every policy decision — from taxes to trade — has economic consequences. Understanding economics helps you evaluate arguments and make informed decisions.

The key insight: Economics isn’t about money — it’s about trade-offs. Every choice has an opportunity cost, and understanding this principle clarifies everything from personal budgets to national policy.

• Basic Economic Concepts — Scarcity, opportunity cost, production possibility frontier, specialisation, division of labour, and economic systems
• Demand, Supply, and Markets — Demand and supply analysis, market equilibrium, elasticity, government intervention, and market failure
• Market Failure and Government Intervention — Externalities, public goods, information asymmetry, taxation, and regulation
• Market Structure and Theory of the Firm — Perfect competition, monopoly, oligopoly, monopolistic competition, and profit maximisation

• National Income and Macroeconomic Indicators — GDP measurement, inflation, unemployment, economic growth, and living standards
• Fiscal and Monetary Policy — Government spending, taxation, money supply, interest rates, inflation, and unemployment
• Money and Banking — Functions of money, banking system, money creation, central bank roles, and monetary policy transmission

• International Trade and Finance — Comparative advantage, trade policies, balance of payments, exchange rates, and trading blocs

• IB Economics: IB Economics
• A-Level Economics: A-Level Economics

Topics with substantial overlap with IB/A-Level content are noted in individual pages where applicable.

Each topic page contains:

• Key concepts and definitions aligned with the HKEAA syllabus

• Worked examples with full calculations and step-by-step solutions

• Data-response practice problems in <details> format for self-testing

• Real-world Hong Kong examples connecting theory to the local economy

1. Time management: The DSE Economics paper is 2.5 hours. Allocate approximately 45 minutes for Section A (multiple choice, 30 questions), 45 minutes for Section B (short answer, 3 questions), and 60 minutes for Section C (extended response, 1 question from a choice of 3).

2. Calculator use: Bring an approved calculator. Practice calculations with it before the exam — do not use your phone.

3. Diagram practice: Memorise the key diagrams: PPC, demand-supply with shifts, consumer/producer surplus, deadweight loss, monopoly diagram, kinked demand curve, AD-AS model, Phillips curve, and the circular flow. Always label axes and curves.

4. Hong Kong context: The HKEAA often sets questions in the Hong Kong context. Be prepared to discuss: the Linked Exchange Rate, public housing, the MPC, land supply, fiscal reserves, CEPA, the Greater Bay Area, and Hong Kong”s structural economic transformation.

5. Evaluation skills: For 7—8 mark questions, always include both analysis and evaluation. Use phrases like “however,” “on the other hand,” ” on,” “in the short run vs long run,” and “this assumes.” Acknowledging limitations and counterarguments earns evaluation marks.
