Suppose the market is monopoly. The market demand function is Q subscript d equals 60 - 0.5 P, where p is the price. The firm has no fixed cost, and the marginal cost MC = 30. a. Write down the marginal revenue of this firm. b. Calculate the profit-maximizing monopolistic price and quantity. c. Calculate the profit of the firm. d. Calculate consumer surplus. After selling the products to the consumers in question (a)-(b), there are still other consumers in the market willing to buy this product at lower price. This firm is able to do price discrimination in the secondary market. e. Write down the demand function and marginal revenue in the secondary market. f. Calculate the price and quantity in the secondary market. g. Calculate the profit of the firm in the secondary market. h. Calculate consumer surplus in the secondary market. i. Show that the welfare loss is less when the firm is able to do price discrimination. You need to calculate the welfare loss before and after the price discrimination respectively. j. Calculate the price elasticity of demand in the first market and in the secondary market.

suppose the market demand function for ice cream is Q^d = 10 - 2P and the market supply function for ice cream is Q^5 = 4P - 2, both measured in millions of gallons of ice cream per year. Suppose the government imposes a $0.50 tax on each gallon of ice cream produced. The price received by sellers with the tax is? a. 2.33 b. 1.50 c. 1.73 d. 1.83

The market demand function for corn is Q(d) = 30- 2P and the market supply function is Q(s)= 5P - 2.5, both measured in billions of bushels per year. Suppose the import supply curve is infinitely elastic at a price of $3.50 per bushel. a. Calculate consumer surplus, producer surplus, and aggregate surplus. b.

Assume that the market demand function is: Q(D) = 2000 - 5P And the market supply function is: Q(S) = 100 + 5P Assume that the government passes legislation that sets the maximum price to $100 a unit. Which of the following statements are correct (multiple statements may be correct)? 1.) At a legally mandated price of $100 a unit, quantity demanded is equal to 1050 and quantity supplied is equal to 1050, therefore the legally mandated price has no...

A monopoly faces market demand Q = 30−P and has a cost function C(Q) = Q^2...

A monopoly faces market demand Q = 30−P and has a cost function C(Q) = Q^2 (a) Find the profit maximizing price and quantity and the resulting profit to the monopoly. (b) What is the socially optimal price? Calculate the deadweight loss (DWL) due to the monopolist behavior of this firm. Calculate consumer surplus (CS) and producer surplus (PS) given the profit maximizing price. (c) Assume that the government puts a price ceiling on the monopolist at P =22. How...

The market demand function for a good is given by Q = D(p) = 800 −...

The market demand function for a good is given by Q = D(p) = 800 − 50p. For each firm that produces the good the total cost function is TC(Q) = 4Q+( Q2/2) . Recall that this means that the marginal cost is MC(Q) = 4 + Q. Assume that firms are price takers. In the short run (with 100 firms), and assume that the government imposes a tax of $3 per unit. (a) What would be the new equilibrium...

12. Suppose a monopoly firm faces the market demand Q = 500 – p and has cost function C = 100 + Q2 . Find the firm’s profit, CS, PS, and DWL for the following scenarios: a. The monopoly firm charges a single price b. The monopoly firm perfectly price discriminate c. The monopoly firm adopts a block-pricing schedule with 2 quantity blocks

(Perfect Competition and consumer Surplus) Suppose the demand function for widgets is Q(p) = 60 – p, and all firms that produce widgets have total cost function C(q) = 16 + q^3 . a) Suppose that the market is perfectly competitive and there is free entry and exit. All firms that enter use the same technology. A firm that decides to stay out of the market can avoid paying the fixed cost and has a profit of zero. Solve for...

Suppose the domestic market demand function in a certain market where Q is measured in thousands of units is Qd = 20 - 2.5P, and the domestic market supply function is Qs = 2.5P - 7.5. Suppose further that the world price for the good in question is $3.40 per unit. a) Under conditions of free trade, how much consumer surplus will there be? b) Under conditions of free trade, how much producer surplus will there be? c) How much...

If a monopoly faces an inverse demand curve of p equals=390390minus−Q, has a constant marginal and average cost of $30, and can perfectly price discriminate, what is its profit? What are the consumer surplus, welfare, and deadweight loss? How would these results change if the firm were a single-price monopoly?

Suppose the market inverse demand function for rubbing alcohol is p = 120 – q. a. What is the consumer surplus if the price is $30? b. Now suppose the price increases to $40. i. What is the reduction in consumer surplus coming from existing buyers who are still able to purchase rubbing alcohol at $40? ii. What is the reduction in consumer surplus coming from buyers who can no longer purchase rubbing alcohol at $40, but were able to...
