1. Unit at a Glance
This unit builds the conceptual base for all microeconomics and macroeconomics study in your A-Level course. We start with the most fundamental question of economics (why does economics exist?) and work incrementally through key definitions, analytical tools, and comparisons of real-world resource allocation systems.
Every concept you learn here will be reused in later units, so taking time to master these foundational ideas will make more advanced topics much easier to understand.
This unit covers the following sub-topics:
Scarcity, choice and opportunity cost
Introduces the core economic problem of scarcity, trade-offs, and the definition of opportunity cost.
β β± 6 min
Positive and normative statements
Teaches the key distinction between factual, testable claims and value-based judgements in economics.
β β± 4 min
Factors of production
Classifies the four categories of productive resources and explains their roles in output.
β β± 4 min
Production possibility curves
Uses the PPC model to illustrate opportunity cost, efficiency, growth, and production trade-offs.
β β β± 7 min
Specialization and division of labour
Explores the key benefits and potential drawbacks of specialization for workers and economies.
β β β± 5 min
Different economic systems
Compares how market, command, and mixed systems answer the three basic economic questions.
β β β± 6 min
Money and its functions
Outlines the four core functions of money that enable modern trade and specialization.

2. Common Pitfalls
Wrong move:
Treating opportunity cost as only the monetary cost of a choice
Why:
Opportunity cost includes all implicit (non-monetary) costs of the next best alternative foregone
Correct move:
Always identify the next best alternative given up, regardless of whether it has an explicit price tag
Wrong move:
Assuming any statement mentioning values must be normative
Why:
A statement can be about values and still be testable (and therefore positive)
Correct move:
Check if the statement can be proven true or false with evidence, rather than just looking at its topic
Wrong move:
Thinking points inside a PPC only represent unemployment of resources
Why:
Points inside the PPC also represent inefficient use of fully employed resources
Correct move:
Interpret all points inside the PPC as productive inefficiency, regardless of the source
3. Quick Reference Cheatsheet
Key Concept / Formula | Core Definition |
|---|---|
Opportunity Cost | Value of the next best alternative foregone when a choice is made |
Positive Statement | Testable, factual claim about how the economy functions |
Normative Statement | Value-based judgement about what economic outcome is desirable |
Factors of Production | Land (natural), Labour (human effort), Capital (man-made aids), Enterprise (organisation/risk) |
Opportunity Cost on PPC | : Units of good Y given up to produce 1 extra unit of good X |
Four Functions of Money | Medium of exchange, unit of account, store of value, standard of deferred payment |
Three Basic Economic Questions | What to produce? How to produce it? For whom to produce it? |
What's Next
This is the first foundational unit of the CIE A-Level 9708 syllabus. Start with the first sub-topic below to build your core knowledge step by step. After completing all sub-topics in this unit, you will move on to Unit 2: The Price System and the Microeconomy, which applies these core concepts to explain how market prices work.
