What this dot point is asking
OCR wants you to explain what competition means and evaluate its economic impact on producers and consumers. You should be able to argue both the benefits of competition and its limits, which sets up the comparison with monopoly and oligopoly.
What competition means
The more competitive a market, the more power consumers have, because firms must work to keep their custom. The opposite of competition is monopoly, where one firm dominates and faces little pressure.
How consumers benefit from competition
Competition tends to improve outcomes for consumers in four linked ways:
- Lower prices. Firms keep prices down to avoid losing customers to rivals, so consumers pay less.
- More choice. To stand out, firms offer a wider variety of products, giving consumers more options.
- Better quality. Firms improve their goods and customer service to win and keep customers.
- More innovation. The pressure to stay ahead drives firms to develop new and better products over time.
How competition affects producers
For producers, competition is a double-edged sword. It forces them to be efficient: firms must keep costs low and quality high or lose customers, so wasteful firms are driven out. But it also squeezes profit margins, because firms cannot charge high prices without losing sales. Competition therefore rewards well-run firms and punishes inefficient ones.
This drive for efficiency benefits the wider economy: scarce resources are used more productively, and firms that cannot compete release their resources for more productive uses elsewhere.
The limits of competition
Competition is not always the best outcome:
- Very low profits can leave firms without the funds to invest or innovate, slowing long-run improvement.
- Wasteful duplication can occur, for example several firms each building their own network where one would do.
- In markets with very high fixed costs (such as water or rail), a single large firm may be cheaper than many small ones, which is why some are regulated rather than fully competitive.

Q2. Explain one reason competition encourages firms to be efficient. [3 marks]
- Cue. Firms must keep costs low and quality high or lose customers to rivals, so inefficient firms are driven out.

OCR J205/01 20194 marksExplain two ways consumers benefit from competition between firms.Show worked answer →
A 4 mark question worth two marks per developed benefit.
First, competition tends to lower prices: firms compete for customers, so they keep prices down to avoid losing sales to rivals, which means consumers pay less.
Second, competition raises quality and choice: to win customers, firms improve products and offer more variety, so consumers get better goods and more options. Markers reward two clearly developed benefits; a bare list of words such as "lower prices, more choice" without explanation earns fewer marks.

A 6 mark evaluative question needing both sides and a judgement.
In favour: competition usually brings lower prices, more choice, better quality and more innovation as firms fight for customers, and it improves efficiency because inefficient firms lose out.
Against: very intense competition can leave firms with low profits, reducing the funds for investment and innovation; it may encourage cost-cutting that harms quality or workers; and some markets (such as utilities with high fixed costs) may work better with fewer, larger firms. Markers reward a balanced answer and a supported judgement, for example that competition usually benefits consumers but not in every market.
