External Environment (AQA A-Level Business): Revision Notes
Costs and Demand
Introduction to external environment
The external environment includes all the factors that exist outside a business's direct control. These factors can significantly influence both the demand for products or services and the costs of running a business. Key external factors include:
- Competition from rival firms
- Market conditions and characteristics
- Economic factors like interest rates and income levels
- Social and demographic changes
- Environmental concerns and sustainability issues
While some external changes can be predicted by spotting trends, others (like the 2008 recession) arrive unexpectedly. Businesses must be prepared to respond to these changing circumstances. It's important to remember that external changes aren't always negative – what harms one business might benefit another.
Competition
Understanding competitive environments
Most businesses face competition from other firms offering similar or identical products and services. The competitive environment refers to the market situation where multiple businesses compete for customers. The strategies competitors use will directly affect your business.
Impact of competition on demand
Competition influences demand in several important ways:
Product differentiation is crucial for success. When many firms sell similar products, a business needs to make its offering stand out. This encourages consumers to choose its products over competitors'. For example, in the UK grocery sector, the major supermarkets (Tesco, Asda, Sainsburys, Morrisons) have all experienced falling demand because discount retailers Aldi and Lidl have attracted customers away.
Innovation can dramatically shift market demand. When a competitor introduces an innovative product or service, it can reshape entire markets. Apple's launch of the iPod and iPhone transformed the technology industry. Businesses that adopt new technology early often benefit, while those that lag behind can suffer. Morrison's slow adoption of online shopping hurt their performance, while HMV failed to anticipate the rise of music downloading and nearly collapsed.
Impact of competition on costs
Competition doesn't just affect demand – it also creates cost pressures. In competitive markets, firms often compete on price. This forces businesses to constantly seek ways to reduce costs wherever possible to maintain profitability while keeping prices attractive to customers.
Exam tip: When analysing competition, always consider how a business can differentiate itself from rivals. This differentiation strategy is essential for maintaining demand and avoiding pure price competition.
Market conditions
Defining market conditions
Market conditions describe the key characteristics of a particular market. These characteristics include:
- Market size (total value or volume)
- Growth rate (how fast the market is expanding or contracting)
- Barriers to entry (obstacles preventing new competitors entering)
- Seasonal factors (predictable fluctuations in demand)
- Intensity of competition (how fiercely firms compete)
Impact on demand and costs
Different market conditions create different opportunities and challenges:
A market with high growth and low competition offers greater opportunities for businesses to increase demand compared to a stagnant or declining market. Conversely, high barriers to entry (like the aeronautical engine market) protect existing operators from new competitors, allowing them to maintain demand and potentially charge higher prices.
Markets with lower barriers might see more new entrants, increasing competition and putting pressure on both demand and costs for existing firms.
Economic factors
Interest rates and their effects
Interest rates represent the cost of borrowing money and the reward for saving. Changes in interest rates can significantly impact both business costs and consumer demand.
Impact on consumer demand
When interest rates rise, several effects occur:
Consumers typically have less disposable income because:
- Borrowing costs increase for loans and mortgages
- People are encouraged to save more (attracted by higher interest rates on savings)
This reduced disposable income generally leads to lower demand for products and services. However, not all businesses are affected equally. Discount retailers might actually benefit as consumers switch from premium grocery stores (like traditional supermarkets) to budget options (like Lidl). Similarly, restaurants like Pizza Hut have gained customers as people cut back on more expensive dining options.
When interest rates fall, the opposite occurs – consumers have more to spend, typically increasing demand.
Impact on business costs
Interest rate changes directly affect businesses with borrowing:
Rising interest rates mean businesses with high levels of debt face increased costs when rates rise. Combined with potentially falling demand, this can severely impact profitability. However, businesses with little borrowing are less affected by rate rises.
Falling interest rates reduce borrowing costs, easing pressure on both demand and costs. Businesses with large cash reserves might actually lose out because they earn less interest on their savings.
Impact on business decisions
Interest rates influence strategic decision-making:
High or rising rates may cause businesses to postpone new capital investment because the costs involved become more expensive. This affects decisions about expanding operations or purchasing new equipment.
Low or falling rates make capital investment more attractive and affordable, encouraging businesses to invest in growth.
Exam tip: Remember the relationship between interest rates and incomes. When interest rates rise, incomes available for spending (disposable income) fall. When rates fall, disposable income rises. They move in opposite directions.
Incomes
How income levels affect demand
The overall level of incomes in the economy is a major demand driver. Income changes affect different products differently:
During periods of falling incomes (like the 2008 recession):
- Overall demand decreases
- Demand for necessities falls less than demand for luxuries
- Consumers prioritize essential spending
During periods of rising incomes:
- Overall demand increases
- Demand for luxury items increases proportionally more
- Consumers have more discretionary spending power
This concept relates to income elasticity of demand – how sensitive demand is to income changes. Necessities show low income elasticity (demand changes little when incomes change), while luxuries show high income elasticity (demand changes significantly when incomes change).
Demographic factors
Understanding demography
Demography is the study of human populations. Key demographic factors include:
- Age distribution of the population
- Gender balance
- Income and occupation patterns
- Birth and death rates
- Public health levels
- Immigration patterns
UK demographic trends
The UK faces two significant demographic trends:
- Growing population – largely driven by immigration
- Ageing population – people are living longer
Impact on businesses
These demographic changes affect businesses in multiple ways:
Demand patterns change: An ageing population demands different goods and services. For example, demand for holidays like cruises has increased as businesses like B&Q actively recruit older workers to serve this growing market.
Working population structure changes: Workers now face the prospect of working longer before receiving the state pension. This affects workforce planning and the types of products and services needed.
Long-term planning required: Businesses must recognize and anticipate demographic changes to adjust their product ranges, marketing strategies, and workforce planning accordingly.
Exam tip: When analyzing demographics, consider both the impact on what customers buy and how the available workforce changes. Demographics affect both demand-side and supply-side factors.
Environmental issues and fair trade
Growing environmental concerns
Businesses today cannot ignore environmental issues without facing serious consequences. Social media and traditional media quickly expose environmental problems, potentially damaging a business's reputation, sales, and costs.
Environmental legislation in the UK
UK governments have introduced extensive legislation to protect the environment from pollution. This regulation requires businesses to invest significant resources in:
- Keeping water sources clean
- Reducing air pollution
- Protecting the countryside
These measures increase business costs, but businesses that locate overseas to avoid stricter UK regulations still face public scrutiny and pressure.
Sustainable development and conservation
Global warming and carbon emissions have become major concerns. Both businesses and governments are expected to reduce emissions contributing to climate change.
Sustainable development has emerged as a business priority due to concerns about depleting natural resources. Businesses should conserve and sustain resources wherever possible. For example:
- The fishing industry operates under quotas
- Paper manufacturers pledge to plant new trees for every tree cut down
Fair trade
Fair trade aims to achieve better prices, decent working conditions, and fair terms of trade for farmers and workers in less developed countries. While this may increase costs for businesses buying from these suppliers, it can also:
- Increase demand from ethically-conscious consumers
- Improve business reputation
- Act as a unique selling point
Preparing for external changes
Although businesses may sometimes face unexpected external changes (like the depth of the 2008 recession), many changes can be anticipated. By identifying predictable changes such as:
- Demographic shifts
- Interest rate trends
- New product developments
Businesses can develop strategies to minimize negative impacts and maximize positive opportunities. This forward planning helps businesses stay ahead of competitors and maintain profitability.
The PESTLE framework
External factors affecting businesses can be remembered using the acronym PESTLE:
The PESTLE Framework:
- Political (government policy, funding, grants)
- Economic (inflation, interest rates, labour costs, energy costs)
- Social (population, education, media, lifestyle, fashion, culture)
- Technological (emerging technologies, web, information and communication)
- Legal (regulations, standards, employment law)
- Environmental (weather, green and ethical issues, pollution, waste, recycling)
Exam tip: Use PESTLE to systematically analyze all external factors affecting a business. This framework ensures you don't miss important environmental influences in your exam answers.
Remember!
Key Points to Remember:
-
External environment factors include competition, market conditions, economic factors, demographics, and environmental issues – all outside the business's direct control.
-
Competition forces businesses to differentiate their products and control costs. Innovation by competitors can dramatically shift demand between businesses.
-
Interest rates affect consumer disposable income and business borrowing costs. Higher rates reduce demand and increase costs; lower rates have the opposite effect.
-
Demographic changes like the UK's ageing population affect both what customers demand and the structure of the workforce. Businesses must anticipate these long-term trends.
-
Environmental responsibility and fair trade are increasingly important. While they may increase costs, they can also boost reputation and demand from ethical consumers.
