Introduction

This article supports the Pearson A Level Economics curriculum, specifically Theme 2.2.3 Investment as a component of aggregate demand. It helps teachers, SLT, careers leads, and headteachers deliver clear conceptual understanding, link to real‑world examples, and ensure exam readiness. Investment makes up roughly 15 % of AD—a significant driver of growth and policy intervention—so it’s essential learners grasp both its theory and practical implications Tutor2u+1Tutor2u+1Office for National StatisticsThe Guardian+1Tutor2u+1Tutor2u+3Pearson Qualifications+3sharnbrook.academy+3Tutor2uPhysics and Maths Tutor+4Pearson Qualifications+4OneMoneyWay+4.

Teaching Notes

• Common pitfalls:

  • Confusing gross and net investment—ensure students calculate depreciation correctly.

  • Using interest rates too simplistically—consider transmission lags and non‑price factors like sentiment.

• Extension activities:

  • Update graphs with ONS business investment data (Q2 2024).

  • Debate: “Tax incentives vs low interest rates: which better stimulates business investment?”

  • Explore LSE/Bennett Institute research on UK’s structural investment gap and its productivity impact Pearson Qualifications+2Pearson Qualifications+2Pearson Qualifications+2Pearson Qualifications+1The Guardian+1Office for National Statistics+1edgenie.co.uk+1Tutor2uBennett Institute for Public Policy.
