Pearson Edexcel A Level Economics B Paper 3 2025 Mark Scheme

Download the official Pearson Edexcel A-Level Economics B Paper 3 mark scheme for the June 2025 examination series (9EB0/03). This examiner-approved PDF contains the complete set of accepted answers, indicative content, examiner guidance, diagrams, assessment criteria, and level-based descriptors used during the official Edexcel marking process for “The economic environment and business”.

The mark scheme provides detailed examiner guidance for every question in the 2025 Edexcel A-Level Economics B Paper 3 assessment. Students can see exactly how marks are awarded for synoptic economic analysis, globalisation evaluation, stakeholder conflict, labour-market analysis, inflation and unemployment trade-offs, market regulation, and business ethics.

Official answers are included for Section A short-answer and essay questions covering diseconomies of scale, firm growth, business objectives, consumer conflict, ethical business behaviour, stakeholder relationships, and the economic effects of globalisation on national and local economies.

The mark scheme explains how Edexcel rewards balanced analysis of economies and diseconomies of scale, including issues such as communication failures, management complexity, resource scarcity, technological change, artificial intelligence, and minimum efficient scale. Examiner guidance also demonstrates how contextual evidence involving Tesco, PepsiCo, and ethical business awards should be integrated into economic reasoning.

Detailed indicative content is provided for questions assessing conflict between business objectives and consumer interests. Students can study how Edexcel rewards discussion of profit maximisation, monopoly power, consumer welfare, market structures, customer satisfaction, consumer protection laws, and ethical business strategies using balanced chains of reasoning and contextual evaluation.

The Paper 3 mark scheme also contains comprehensive examiner guidance for evaluating ethical business behaviour and stakeholder conflict. Official answers include analysis of sustainable business practices, fair treatment of employees and suppliers, environmental responsibility, opportunity cost, shareholder returns, ethical consumer behaviour, and long-run impacts on sales, loyalty, market share, and profitability.

Extensive examiner commentary is included for the 20-mark essay evaluating the effects of globalisation on local and national economies. Students can learn how Edexcel rewards analysis of free trade, foreign direct investment, migration, technological change, poverty reduction, labour-market expansion, trade wars, inequality, environmental degradation, biodiversity loss, deforestation, and protectionist policies.

Section B examiner guidance focuses on labour markets, supply-side policies, inflation, unemployment, and market regulation. Official answers explain how Edexcel rewards analysis of national living wage increases, labour costs, employment effects, disposable income changes, aggregate demand impacts, and price elasticity considerations using contextual evidence from firms such as Pets at Home and Currys.

The mark scheme also includes detailed evaluation guidance for supply-side policies designed to reduce skills shortages in the UK construction industry. Students can study how Edexcel rewards discussion of occupational mobility, education and training investment, subsidies, tax incentives, migration policy, time lags, opportunity costs, and political trade-offs associated with labour-market reforms.

Comprehensive examiner commentary is provided for the question assessing the trade-off between inflation and unemployment. Official indicative content includes analysis of aggregate demand, labour demand, Phillips-curve relationships, stagflation, supply-side shocks, inflation trends between 2019 and 2024, unemployment movements, and the effects of global events on UK macroeconomic performance.

The mark scheme also contains extensive guidance for evaluating the benefits of regulation in markets. Students can study how Edexcel rewards discussion of market failure, consumer protection laws, competition policy, regulatory bodies, merger investigations, anti-competitive behaviour, environmental regulation, compliance costs, bureaucracy, contestability, economies of scale, and regulatory capture.

Official level-based descriptors clearly explain how Edexcel distinguishes between isolated, competent, analytical, and sophisticated Economics responses across knowledge, application, analysis, and evaluation. Students can see how contextual evidence, coherent chains of reasoning, balanced judgement, and nuanced evaluation contribute to higher-band A-Level Economics B marks.
