one key difference between an oligopoly market and a competitive market is that oligopolistic firms:

A: are price takers while competitive firms are not

B: can affect the profit of other firms in the market by the choices they make while firms in competitive markets do not affect each other by the choices they make

C: sell completely unrelated products while competitive firms do not

D: sell their product at a price equal to a marginal cost while competitive firms do not

Solution

B: can affect the profit of other firms in the market by the choices they make while firms in competitive markets do not affect each other by the choices they make
