This unit introduces the foundational economic concepts that underpin all other topics in the 9708 syllabus. You will learn how societies address the core problem of scarcity and allocate limited resources to meet unlimited wants.

**Prerequisites:** No prior economics knowledge is required for this unit

## Learning objectives

- Explain the core economic problem of scarcity and how it drives individual and societal choice
- Distinguish between positive and normative analysis, the two foundations of economic reasoning
- Classify factors of production and describe their distinct roles in producing goods and services
- Interpret production possibility curves to illustrate opportunity cost, efficiency, and economic growth
- Compare how different economic systems answer the three basic questions of resource allocation

## 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](https://www.owlsprep.com/study/cie-9708-u1-scarcity-choice-and-opportunity-cost/) — Introduces the core economic problem of scarcity, trade-offs, and the definition of opportunity cost.
- [Positive and normative statements](https://www.owlsprep.com/study/cie-9708-u1-positive-and-normative-statements/) — Teaches the key distinction between factual, testable claims and value-based judgements in economics.
- [Factors of production](https://www.owlsprep.com/study/cie-9708-u1-factors-of-production/) — Classifies the four categories of productive resources and explains their roles in output.
- [Production possibility curves](https://www.owlsprep.com/study/cie-9708-u1-production-possibility-curves/) — Uses the PPC model to illustrate opportunity cost, efficiency, growth, and production trade-offs.
- [Specialization and division of labour](https://www.owlsprep.com/study/cie-9708-u1-specialization-and-division-of-labour/) — Explores the key benefits and potential drawbacks of specialization for workers and economies.
- [Different economic systems](https://www.owlsprep.com/study/cie-9708-u1-different-economic-systems/) — Compares how market, command, and mixed systems answer the three basic economic questions.
- [Money and its functions](https://www.owlsprep.com/study/cie-9708-u1-money-and-its-functions/) — Outlines the four core functions of money that enable modern trade and specialization.

## Common pitfalls

- **Wrong:** Treating opportunity cost as only the monetary cost of a choice
  - Why it fails: Opportunity cost includes all implicit (non-monetary) costs of the next best alternative foregone
  - Correct: Always identify the next best alternative given up, regardless of whether it has an explicit price tag
- **Wrong:** Assuming any statement mentioning values must be normative
  - Why it fails: A statement can be about values and still be testable (and therefore positive)
  - Correct: Check if the statement can be proven true or false with evidence, rather than just looking at its topic
- **Wrong:** Thinking points inside a PPC only represent unemployment of resources
  - Why it fails: Points inside the PPC also represent inefficient use of fully employed resources
  - Correct: Interpret all points inside the PPC as productive inefficiency, regardless of the source

## 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 | $\frac{\Delta Y}{\Delta X}$: 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.

- [Scarcity, choice and opportunity cost](https://www.owlsprep.com/study/cie-9708-u1-scarcity-choice-and-opportunity-cost/)
- [Positive and Normative Statements](https://www.owlsprep.com/study/cie-9708-u1-positive-and-normative-statements/)
- [Factors of Production](https://www.owlsprep.com/study/cie-9708-u1-factors-of-production/)
