Question:
You are analyzing a certain oligopolist industry with of only two companies: firm A and firm B. Both companies have a production process with constant marginal costs of $2000. Assume there are no fixed costs.
As a consequence of a change in the operating structure of firm B, their marginal cost increased to a constant amount of $2100. Firm A still produces at the same marginal cost as before.
What happens to each firm’s profits and output in the new equilibrium in each of the following oligopoly markets:
- Cournot oligopoly
- Sweezy oligopoly
- Bertrand oligopoly
