Competitive And Concentrated Markets

Bayani Gaba-gaba

Walk down a street with eleven food stalls and you will find eleven prices within a few cents of each other. Walk into a country where one company supplies all the electricity and there is one price, take it or leave it. The good being sold is not what makes the difference. The number of sellers is.

This lesson is about market structure: how many producers there are, how different their products are, and how easy it is for a new firm to walk in. You will learn what happens to price, choice, quality and profit as a market moves from many sellers to very few, why a monopolist can do things a market trader cannot, and what an oligopoly is. Then you will apply demand and supply to a market you have not yet analysed with them: the market for labour, where the price is a wage, and where the same tools explain why a surgeon earns many times what a shelf-stacker does.

Takardar Darasi

Suppose you are selling roasted maize on a street where ten other people sell roasted maize. Try charging twice what they charge and you will sell nothing, because your customer simply walks four metres to the next stall. Now suppose you are the only electricity company in the country. Raise your price and your customers cannot walk anywhere, because there is nowhere to walk to.
