PEST analysis: the political, economic, social and technological factors of the external environment, their effects on business, and the use of PEST to analyse opportunities and threats.

What this dot point is asking

WJEC Unit 4 uses PEST analysis to examine the external (macro) environment: the political, economic, social and technological factors that affect a business but lie outside its control. Strong answers do not just list factors; they trace how each affects a specific firm (its costs, demand or strategy) and use PEST to identify opportunities and threats.

The answer

What PEST analysis is

Political factors

Political factors are the effects of government and politics: taxation (corporation tax, VAT), regulation and legislation (employment, health and safety, environmental rules), government spending and policy, trade policy (tariffs, agreements) and political stability. A change such as a tax rise or new regulation can raise a firm's costs or open or close markets.

Economic factors

Social factors

Social factors are changes in society: demographics (an ageing population, migration), lifestyle and attitudes (health-consciousness, working patterns), culture and values, and ethical and environmental expectations. They shift what customers want and how firms are expected to behave, creating both opportunities (new products) and threats (declining demand for outdated products).

Technological factors

Technological factors are advances in products (new goods to sell), processes (automation, more efficient production), the internet and e-commerce (new ways to reach customers), and data and communications. Technology can lower costs, create new markets and products, and disrupt firms that fail to keep up.

Using PEST

PEST is used to scan the environment before making strategic decisions, sorting external forces into the four headings to reveal opportunities to seize and threats to counter (it links closely to the SWOT opportunities and threats). Its limits are that it only identifies factors (it does not decide), it dates quickly in a fast-changing world, and judging each factor's impact is uncertain - so it must be updated, prioritised and combined with judgement.

Examples in context

Example 1. Economic factors hitting a luxury firm. A premium goods retailer is hit hard when interest rates rise and the economy slows: borrowing is dearer, consumers cut discretionary spending, and demand for its high-end products falls (high income elasticity). A PEST scan would have flagged the economic cycle as a major threat, prompting the firm to build resilience. The example shows economic factors as often the most powerful in PEST.

Example 2. Technological and social opportunity. A traditional firm spots, through PEST, a social shift towards online shopping and sustainability and a technological opportunity in e-commerce, and responds by launching an online sustainable range. By scanning the environment it turned external change into a strategic opportunity ahead of slower rivals. The example illustrates PEST used proactively to find opportunities, not just threats.

• Cue. Political, Economic, Social and Technological factors of the external environment.

Q2. Explain how a rise in interest rates (an economic factor) could affect a business. [3 marks]

• Cue. A rise increases the cost of borrowing for the firm and raises loan and mortgage costs for consumers, reducing consumer spending and demand and making the firm's investment dearer.
