Let demand for car batteries be such that q = 100 − 2p. assume constant marginal costs of 25. compute the equilibrium price, quantity, consumer surplus, producer surplus and if relevant deadweight loss for:

a perfectly competitive market
a monopoly
two firms engaged in cournot competition.
two firms engaged in bertrand competition.
repeat the above, excluding bertrand competition, for a model 2 where firms have a fixed cost for all production greater than zero of 5 dollars. note that the perfectly competitive outcome is hard to define. so lets replace that with a simple version of monopolistic competition. using a zero-profits condition as a guide for the amount of entry what would be the outcome for this market (including the number of firms) following monopolistic competition?

answer the second part of the question repeat the above etc..
