PRC 3 Business and Economic Insights Study Companion | Volume II: Economics | BGB-360

Build a Strong Foundation in Economics

The PRC 3 Business and Economic Insights Study Companion — Volume II is an original, examination-focused learning resource prepared by the BGB-360 Academy Academic Team. It is useful to PRC 3 candidates and to anyone studying introductory economics or the economic side of business.

The companion explains how economic choices, markets, firms, national income and policy decisions fit together. It develops the reasoning behind definitions, diagrams and calculations, then shows how to apply them to business and economic situations.

Each chapter moves from learning outcomes and examination focus to clear explanations, worked illustrations, practice questions, explained answers and revision controls. This structure helps readers understand a topic, test it, diagnose errors and revisit weak areas.

The book supports independent study, classroom learning and structured revision. It may be used alongside lectures and the official PRC 3 Volume II Study Text and Question Bank.

Complete Chapter Coverage

Chapter 1 — Nature and Scope of Economics

Explore scarcity, choice and opportunity cost. The chapter introduces economic questions, the role of economic systems and the distinction between individual decisions and economy-wide outcomes.

Chapter 2 — Demand, Supply and Market Equilibrium

Understand how buyers and sellers influence price and quantity. Learn to distinguish movements along curves from shifts, determine market equilibrium and explain the effect of changing market conditions.

Chapter 3 — Elasticity of Demand and Supply

Measure how strongly quantity responds to changes in price, income and related factors. Use elasticity calculations and interpretation to connect market behaviour with pricing and revenue decisions.

Chapter 4 — Firm Theory

Examine production, costs, revenue, profit and market structures. Apply marginal and average measures to understand how a firm makes output and pricing decisions.

Chapter 5 — National Income and Its Determination

Learn what national income measures, how key aggregates relate to one another and why the method of measurement matters. Interpret nominal and real values and the forces affecting equilibrium income.

Chapter 6 — Consumption, Saving and Investment

Study how income is allocated between consumption and saving, how the related propensities are calculated and why investment matters for economic activity.

Chapter 7 — Multiplier and Accelerator

Trace how changes in spending can affect national income. Work through multiplier calculations, recognise leakages and connect changes in demand to investment through the accelerator concept.

Chapter 8 — Public Finance

Understand government revenue, public spending, taxation and borrowing. Consider how fiscal choices affect economic activity and the decisions of households and businesses.

Chapter 9 — Money

Review the functions and forms of money and the role of banks. Connect the banking system, credit creation and central-bank activity with the wider economy.

Chapter 10 — Inflation and Unemployment

Identify causes, measures and consequences of inflation and unemployment. Compare possible policy responses and consider how these problems affect households, firms and economic performance.

Chapter 11 — Monetary Policy

Examine monetary-policy objectives and instruments, including interest rates and bank-reserve measures. Follow how policy changes can affect lending, spending, output and prices.

Chapter 12 — Balance of Trade and Payments

Learn how international transactions are recorded. Distinguish trade and current-account measures, work through balances and consider the effects of trade policy and external imbalances.

Volume II Cumulative Examination Practice

Bring the chapters together through 60 original objective questions and six integrated scenarios. Explained answers, a topic diagnostic and a completion record support focused revision after the first attempt.

Designed for Active Study

Economics becomes more useful when a learner can explain a relationship, apply it to a new situation and interpret the result. Reading a definition alone does not show whether that understanding is secure.

This companion supports a five-stage study cycle:

1. Preview: Read the learning outcomes and identify the central economic question.
2. Learn: Study an explanation and work through the illustration.
3. Practise: Attempt an original question or scenario independently.
4. Diagnose: Compare your reasoning with the explained answer and record errors.
5. Retake: Revisit weak topics and attempt them again after further study.

Three Flexible Study Routes

Routine Chapter-by-Chapter Study

Work through one chapter at a time, complete its practice, record errors and retest before moving on. This route suits learners building their understanding alongside classes or other commitments.

Focused Preparation

Prioritise highlighted definitions, formulas, worked illustrations and objective practice. Use the cumulative topic diagnostic to decide where additional study is needed.

Pre-Examination Review

Review rapid-recall points, common errors, chapter retest records and cumulative practice. Check current official instructions separately for the online examination interface and rules.
