Question

Which of the following is NOT a necessary condition for oligopoly? differentiated products barriers to entry strategic dependence of firms either a small number of firms or market dominance by a small number of firms

Answer 1

differentiated products.

Step-by-step explanation:

An oligopoly occurs when a few large firms dominate a market and they aim to maximise profit. The action of one firm has significant effect on the market, so the firm's are interdependent.

There are high barriers to entry including use of government liscences, patents, economies of scale, and actions taken by firms to discourage entry into the market.

However differentiation of products is not a necessary condition for oligopoly. Products can be homogenous or differentiated.
