A firm produces two different goods, with demand given by the following:
Pa = 100 – 3Qa + 2Qb and Pb = 105 – 8Qb Where Pa = price of good A, Pb = price of good B, Qa = quantity of good A and Qb = quantity of good B. The marginal costs for the two goods are 12 for good A and 15 for good B.
Determine optimal prices and quantities for each good.

Bonus (5 points) True or False: Consider a monopolist which produces two interrelated goods A and B with QA(PA, PB) and QB(PA, Pa) where Q is the demand and P is the price. If dA-0, the firm could charge the same price as a monopolist in market A which produces only good A. Explain your answer. (Answers without correct explanation will receive 0 credit.)

Anna’s demand for peaches is given by PA = 200 – 3QA, where QA is the quantity (kilograms) demanded at price PA($/kilo). Basil’s demand is given by PB = 120 – 2QB, where QB is the quantity (kilograms) demanded at price PB ($/kilo). Each of the two has $2,000 that they can spend if they want to buy something. Suppose the endowments are as follows: Anna has 110 kilograms of peaches, Basil has none. When they trade, who will sell...
A firm's market demand for its product in the company’s country, a, is given by Qa(Pa) = 1,050 − 4Pa, where Qa is the quantity of products produced per year and Pa is the price product. Cost of producing this product is ?(Q) = 70,125 + 0.0125Q2. This implies a marginal cost of production of ?C(q) = 0.025Q. a) Find the profit-maximizing price and quantity. Compute the firm’s profit in this case. Should the firm shut down in the short...
A) Suppose a monopoly sells to two identifiably different types of customers, A and B, who are unable to practice arbitrage. The inverse demand curve for group A is PA = 29 - QA, and the inverse demand curve for group B is PB = 19 - 2QB. The monopolist is able to produce the good for either type of customer at a constant marginal cost of 3, and the monopolist has no fixed costs. If the monopolist practices group...
22. Suppose a monopoly sells to two identifiably different types of customers, A and B, who are unable to practice arbitrage. The inverse demand curve for group A is PA 20-QA, and the inverse demand curve for group B is PB 20-2QB. The monopolist is able to produce the good for either type of customer at a constant marginal cost of 4, and the monopolist has no fixed costs. If the monopolist practices group price discrimination, what are the profit...
Consider a market with two firms, A and B, producing a differentiated product. The demand for the products of firms A and B are, respectively, QA = 60 – 2pA + pB and QB = 60 – 2pB + pA, where pA is the price of firm A and pB is the price of firm B. Each firm has a constant marginal cost of production which is equal to 30 and no fixed costs. The firms choose prices only once...
A firm produces two goods (the quantities of the two goods are denoted, Q1 and Q2). The demand functions are Pi = 50-0.0075Q1 and P.-40-0.004Q2. Total cost is given by TC 19,800 + 20Q1 + 2002, Marginal costs are constant, so pricing at marginal costs results in a loss of the fixed costs for the firm. To eliminate this loss, prices must be raised. The regulator is considering three different possible sets of prices: Set 1: P121 and P2 23.98...
In Little Town, there are two suppliers of mineral water: A and B. Mineral water is considered a homogenous good. Let pA and pB denote the price and qA and qB the quantity sold by firms A and B, respectively. Suppose that the municipality provides all the water for free, so firms don't bear any production cost. The inverse demand function for mineral water is given by P=12-1/3Q where Q=qA + qB denotes the aggregate supply of mineral water. Suppose...
Section B. Short Answer Question (2 questions, 20 points each) Question 1 (20 pts) The following data pertain to products A and B, both of which are purchased by Emily. Emily has $105 to spend per time period. Initially, the prices of the products are PA $5, PB $10. And Emily's optimal consumption bundle is O1 {QA = 5, QB- 8}. 1.1) What is Emily's marginal rate of substitution when she consumes the bundle O1, i.e., ΔΑ MUB MRS MUA...
Two airlines compete for passengers on a one-way flight Philadelphia Orlando, FL. They differentiate their products primarily on product quality, with Firm A providing more upscale service, while Firm B operates more as an economy airline. The demand curve for Firm A's product (upscale service) is: Qa- 720-2Pa PB, Firm B has a product (economy service) demand curve equal to: QB-528-3Ps + 2PA The marginal cost for firm A is $70 per passenger, for firm B it is $40 per...
