CAPE Economics Unit 1 · Work through your exam, one topic at a time.
CAPE Economics Unit 1 is the first of two independent units in the Caribbean Advanced Proficiency Examination Economics syllabus, offered by the Caribbean Examinations Council (CXC). Unit 1 focuses on microeconomics and is one of the three modules that make up the unit: Methodology: Demand and Supply; Market Structure, Market Failure and Intervention; and Distribution Theory. Each module requires approximately 50 hours of instruction, totaling 150 hours per Unit. The syllabus is designed for students who wish to understand how individuals, households, firms, governments and international institutions allocate scarce resources, and it develops skills in applying economic concepts, analysing data, evaluating policies and making evidence-based judgments. Topics on this exam: Methodology: Demand and Supply, Market Structure, Market Failure and Intervention, and Distribution Theory. The CAPE Economics Unit 1 study guide has 3 sections and about 1,547 words.
01Methodology: Demand and Supply
CAPE Unit 1's methodology domain asks you to model scarcity and choice with the circular flow, PPC and demand-supply diagrams, and to distinguish positive from normative statements. The exam rewards correct ceteris paribus reasoning, labelled diagrams and elasticity calculations, not descriptive prose. A demand curve shows the quantity buyers plan to buy at each price, ceteris paribus; a change in price moves along it, while income, tastes, prices of substitutes/complements, expectations or population shift it. Supply is the planned quantity sellers offer; input costs, technology, taxes/subsidies, expected prices and number of firms shift supply.

CAPE Unit 1 tests how market structure changes price, output and efficiency. You must compare perfect competition, monopoly, monopolistic competition and oligopoly using assumptions, revenue diagrams and the profit-maximising rule MR = MC. Expect questions on barriers to entry, concentration ratios, collusion, price discrimination and dynamic versus allocative efficiency. Perfect competition: many price-taking firms, homogeneous product, free entry/exit, perfect information.

This domain examines why free markets may fail to allocate resources efficiently and how governments intervene. CAPE Unit 1 expects externalities, public goods, merit and demerit goods, asymmetric information, market power and inequality, plus evaluation of taxes, subsidies, price controls, regulation and tradable permits. Negative externality: MSC MPC, so the free market overproduces. A Pigouvian tax equal to marginal external cost at the social optimum corrects the gap.
