OCR A Level Business: External Influences Facing Businesses (H431)

This guide covers External influences — the name the specification’s subject content gives this Area of Study in OCR A Level Business (H431); its content overview lists it as “External influences facing businesses”. The specification does not number its areas. In the subject content it comes after Introduction to business and Business objectives and strategy, and shifts the focus from decisions a business makes internally to the market and wider environmental forces it must respond to but cannot fully control.

Syllabus coverage

OCR A LEVEL BUSINESS H431 – AREA OF STUDY: EXTERNAL INFLUENCES

• Markets – the market, market size and growth (explaining what a market, competition, market size and market growth mean, and evaluating how a business could increase market share); the features of monopoly, oligopoly and monopolistic competition, and the relationship between market structure and a firm’s decision-making power; demand and supply, including how changes in their determinants affect price and output, and constructing and interpreting demand-and-supply diagrams to show excesses, shortages and equilibrium.
• Market forces and competition – evaluating the impact of market forces on a business and its stakeholders, and how a business should respond; the distinction between physical and non-physical (online, digital) markets and why firms choose to operate in each; how the strength of competition affects a business, and why firms enter or exit a market; and market dominance – how mergers, acquisitions and organic growth can create dominant firms, and how the UK regulates and restricts market dominance.
• The global context – globalisation and the factors that facilitate it (the internet, communication technologies, e-commerce, trade liberalisation, transport infrastructure and multinationals); the role of multinationals and global branding; international trade and free trade, including barriers to trade, exchange rates and currency conversion, trading blocs, and the factors a business must consider when trading internationally (language, culture, logistics, currency); the influence of the European Union, including its enlargement and the single European currency, and the advantages and disadvantages to a UK business of not being part of the EU and the Eurozone, and of not being a member of the Single European Market; and emerging markets and changes in the global environment.
• PESTLE-style factors – political factors (political stability and uncertainty, and the effect of government policy at local, national, EU and international level); economic factors (key economic indicators, taxation, government expenditure, subsidies, monetary/fiscal/supply-side policy, GDP, and the business cycle); social factors; technological factors and the digital revolution (the information age, and the opportunities and threats of rapid technological change); ethical factors (distinguishing law from ethics, and the trade-offs of ethical trading); legal factors (legislation covering employment, equality, company and partnership structure, health and safety, data protection, intellectual property, planning, environment, consumer protection, contract and financial conduct); and environmental factors.

Why this topic is examined as a connected whole, not a checklist

It is tempting to treat this area of study as a long list of factors to memorise, but OCR’s own assessment objectives weight evaluation and analysis as heavily as knowledge, so exam questions consistently ask you to judge which external influence matters most in a given business scenario, and why, rather than simply list every possible factor. A strong answer on, for example, a small UK manufacturer facing rising import costs will explain the specific link between exchange rate movements (global context) and input costs (economic factors), rather than separately describing “economic factors” and “the global context” as unconnected checklist items. This is precisely why the specification groups markets, competition and global/PESTLE factors together under one topic – they are meant to be argued together.

Market structure and decision-making power

Monopolistic competition, oligopoly and monopoly are the three market structures named in the specification, and each is linked to a business’s decision-making power and the barriers to entry and exit in that market. A stronger evaluative answer identifies where a real business sits between these structures and how much pricing and strategic freedom that position gives it, rather than simply naming the “correct” category from a textbook definition.

Common mistakes

• Listing PESTLE factors without applying them to the specific business in the question. A generic explanation of “political factors affect businesses” earns far fewer marks than one that names the specific policy and traces its effect on the named business’s costs, revenue or strategy.
• Treating globalisation as purely positive. The specification explicitly requires evaluation of both opportunities and threats, including the risk that a business is more exposed to competition, currency movements and international market shocks the more global it becomes.
• Confusing market dominance with simply being a large firm. Dominance is about decision-making power over price and output relative to competitors, not size alone – a large firm facing low barriers to entry or exit may have little real dominance.
• Discussing ethical and legal factors as identical. The specification explicitly requires distinguishing law (compulsory, enforceable) from ethics (a business choice, not a legal requirement), and exam questions test this distinction directly.
• Ignoring the digital revolution as a distinct factor separate from “technological factors” generally – the specification treats the information age and rapid technological change as having their own specific opportunities and threats worth analysing separately.

How to approach it

Build a bank of real, named business examples for each external influence as you revise – a genuine case of a company responding to exchange rate change, a real merger creating market dominance, an actual example of ethical or environmental pressure changing a business’s practice – because questions on this area of study consistently reward specific, current evidence over generic theory. Practise explicitly weighing conflicting influences against each other (for example, cost pressure from economic factors against reputational pressure from ethical factors) since the specification’s higher-mark questions require exactly this kind of trade-off judgement. Revise market structures and market forces together with the global/PESTLE factors, rather than as separate blocks, since real exam scenarios typically combine a market-structure question with an external-influence context in the same case study.
