4 marks

Unit 1 · 1.3.1 Introductory Concepts · Knowledge & Application

Explain: what is meant by scarcity and opportunity cost.

Mark Scheme Breakdown

1–2 marksDefinition of scarcity (unlimited wants, limited/finite resources)

3–4 marksDefinition and application of opportunity cost (next best alternative forgone with example)

KKnowledge/Definition

AApplication

Model Answer

Scarcity is the fundamental economic problem — it arises because human wants are unlimited, yet the resources available to satisfy those wants are finite. K Because resources (land, labour, capital, enterprise) are scarce relative to wants, societies must make choices about how to allocate them. K

Opportunity cost is the next best alternative forgone when a choice is made. K For example, if the UK government chooses to spend £50bn on the HS2 rail project, the opportunity cost is the hospitals, schools, or tax cuts that money could have funded instead. A Opportunity cost exists because of scarcity — if resources were unlimited, choosing one option would not require giving up another. A

Examiner Commentary

Both terms must be defined precisely. Scarcity must reference the tension between unlimited wants and limited resources — not simply "things are rare." Opportunity cost must include "next best alternative forgone," not just "what you give up." The HS2 example grounds the answer in a real-world context, earning the application marks that push into the top band.
