A monopoly has the cost function c(y)=10y+100, and is facing a market demand D(p)=100-2p.

What is the inverse demand function, p(y)? Having profits be π = p(y)∙y – c(y), what is the profit maximizing output level? What is the corresponding market price?

Calculate the monopolist’s profit and producer surplus. What is the consumer surplus? What is the deadweight loss?

The government imposes a production tax, t_P=10, so that the new cost function is c(y)=(10+t_P)y+100. What happens to y and p? What happens to the firm’s profit and producer surplus? What happens to consumer surplus and the deadweight loss? How much is tax revenue?

The government imposes instead a lump sum tax, T=300, so that the new cost function is c(y)=10y+100+T. What happens to y and p? What happens to the firm’s profit and producer surplus? What happens to consumer surplus and the deadweight loss?

The government imposes instead a sales tax, t_S=25%, so that the new demand function is D(p)=100-2p(1+t_S). What happens to y and p? What happens to the firm’s profit and producer surplus? What happens to consumer surplus and the deadweight loss? How much is tax revenue?

The government imposes instead a profit tax, τ=40%, so that the new profit function is π=(1- τ)[p(y)∙y–c(y)]. What happens to y and p? What happens to the firm’s profit and producer surplus? What happens to consumer surplus and the deadweight loss? How much is tax revenue?

The government decides instead to subsidize production with a subsidy, s = 10, so that the new cost function is c(y)=(10-s)y+100. What happens to y and p? What happens to the firm’s profit and producer surplus? What happens to consumer surplus and the deadweight loss? How much is tax revenue?

1. Assume the market demand function is D(P)=100 – P and the firm cost function is C(q)= 20q. The industry is populated by many small firms that offer identical products. In the absence of regulation, a competitive equilibrium would be achieved. However, regulation is in place and requires that a firm’s price be at least as great as 30. Derive the effect of regulation on quantity, firm profits, and social welfare. 2. Now think that the industry is deregulated. What...

Given the Demand function from Part 1: D(p) = 64 2p , The monopolist's cost is equal to C(Q) = Q2 + 2Q: PART II. Now take the same demand function as in Part I but imagine that the market has two firms instead of 1. Also assume that the marginal cost of each firm is equal to 4. Market structure is therefore characterized as a duopoly. Suppose that firms compete by choosing their output levels simultaneously. (14) (2 points)...
