Business Competition

Overview

Walk down any high street and you will see two very different kinds of business: a corner shop selling almost identical bread and milk to twenty rivals within walking distance, and a single national water company that every household in the region must buy from because there is no alternative supplier. Both are real market structures, and the amount of competition each firm faces changes almost everything about how it behaves.

In this lesson you will travel along the spectrum of market structures from highly competitive markets to monopoly, examine why some firms grow large while others deliberately stay small, and unpack the barriers that keep monopolies and oligopolies protected from new rivals. You will finish able to judge, for a given market, whether more competition or more concentration serves consumers better.

Objectives

  1. Advantages and disadvantages of competition to firms, consumers and the economy, including efficiency, choice, quality, innovation, price
  2. Advantages and disadvantages of large firms and small firms
  3. Factors influencing the growth of firms: government regulation, access to finance, economies of scale, the desire to spread risk, the desire to take over competitors
  4. Reasons firms stay small: size of market, nature of market (niche), lack of finance, aims of the entrepreneur
  5. Definition of monopoly
  6. Main features of monopoly: one business dominates the market, unique product, price-maker, barriers to entry (legal barriers, patents, marketing budgets, technology, high start-up costs)
  7. Advantages and disadvantages of monopoly: efficiency, choice, quality, innovation, price, economies of scale
  8. Definition of oligopoly
  9. Main features of oligopoly: few firms, large firms dominate, different products, barriers to entry, collusion, non-price competition, price competition
  10. Advantages and disadvantages of oligopoly: choice, quality, innovation, collusion and cartels fixing high prices, price wars between oligopolies

Lesson Note

Every market sits somewhere on a spectrum. At one end, a huge number of small firms sell a near-identical product and none of them is big enough to influence the market price on their own; economists call this perfect competition, and fresh-vegetable stalls or small family farms come close to it in practice. At the other end, a single business supplies the entire market with no close substitute available; this is monopoly. In between sit markets dominated by a small number of large firms, known as oligopoly. Where a market sits on this spectrum shapes the price customers pay, the choice on offer, and how hard firms have to work to keep improving.
