8. Consider a homogeneous-product duopoly where each firm initially produces at a constant marginal cost of $100 and there are no fixed costs. Determine what would happen to each firm’s equilibrium output and profits if firm 2’s marginal cost increased to $110 but firm 1’s marginal cost remained constant at $100 in each of the following settings:

a. Cournot duopoly.

b. Sweezy oligopoly.
