Explore why competition usually helps consumers.
Key ideas
Competition protects consumers
When several firms compete, each must offer better value to win customers, which lowers prices and improves quality and choice. A monopoly — one seller with no rivals — can charge high prices because customers have nowhere else to go.
Markets connect buyers and sellers
Buyers want the lowest price and best quality; sellers want the highest price they can get. The market is the meeting point — physical like a farmers' market or digital like an auction site — where their offers are matched and trade happens.
Key term — demand: The quantity of a good consumers are willing and able to buy at each price; it generally rises as price falls.
Two stalls sell identical lemonade on one street. Stall A charges 80p, stall B charges 50p. Explain what happens.
Customers compare the two prices and queue at stall B. Stall A loses sales and must respond: cut its price or offer something extra. Prices converge towards 50p as the stalls compete. If the stalls secretly agreed to both charge 80p, that would be collusion — illegal in most countries.
Answer: Competition drives the price towards 50p and consumers benefit. Stall A must match B's price or lose its customers.
- Believing competition always lowers quality Competition usually raises quality, because firms must attract customers; it is monopolies that can afford to be sloppy.
- Thinking markets are only physical places Online marketplaces and stock exchanges are markets too — what matters is buyers meeting sellers, not the building.
Practice
It removes competition, keeping prices high and harming consumers.
Any physical market (e.g. a farmers' market) and any digital one (e.g. an auction website or stock exchange).
Rival firms undercut each other to attract buyers, driving prices down.
A market with a single seller and no close rivals.
