Consider a market where two firms produce the same product, and compete by choosing the price to charge consumers. There are no capacity constraints and no fixed costs. Consumers purchase from the firm that charges the lowest price, Pmin Aggregate demand is given by Q(Pmin) = 600 – 30pmin. Both firms have marginal costs of c = 15. What is the aggregate quantity produced in this market? And what price do consumers pay? (a) p₁ = = 15, p2 = 20, Q = 150 (b) P1 = P2 = 15, Q = 150 (c) P₁ = P₂ = 20, Q = 0 (d) p₁ = 10, P2 = 15, Q = 300 (e) None of the above options is correct.
Suppose that all firms in a constant-cost industry have the following long-run cost curve:c(q) = 4q2 + 100q + 100The demand in this market is given by QD = 1280 - 2p. Suppose the number of firms in the market is restricted to 80a. Derive the supply curve with this restriction. Find the market equilibrium price and quantity with the restriction.b. If firms are allowed to buy and sell these permits in an open market, what will be the rental price of permits? Will firm’s that own permits make profit? Briefly explain.c. How much deadweight loss is generated by the permit system? Provide a graph showing the region of this deadweight loss.d. Suppose the government abandons the permit system and simply imposes a fixed fee on firms in the market. If the fee is set equal to the permit price you found in c., what will be the equilibrium price, quantity, number of firms and deadweight loss?
Please select all that are true regarding Minimum Efficient Scale (MES): if the quantity demanded is equal to Qmes, then the lowest cost solution is for one firm to supply the market MES is the quantity produced where average costs for a firm are at a minimum Long run average costs include fixed cost steps as quantities (scale) increase Quantities (x-axis) less than MES exhibit decreasing returns to scale due to diminishing marginal returns Short run average cost curves are for a given level of fixed cost, individually MES is the quantity demanded where total costs for a firm are at a minimum Quantities (x-axis) greater than MES exhibit decreasing returns to scale due to diminishing marginal returns Average costs do not include fixed cost since they don't change
Consider a competitive market where there are two types of firms, Type A and Type B, with total cost functions TC^(q) =1+2q + q² TC (g) = 6+2q + 3q? (a) Derive the short-run supply curve for each firm type (b) What is the short-run market supply, if there are 10 Type A firms, and 6 Type B firms? (c) What is total quantity produced when p=5? (d) How does your answer at (c) change if we consider long run supply rather than short run? Here, assume again that p=5 and that there are 10 Type A firms and 6 Type B firms.

An industry has the following cost function: C(X, Y ) = 1500+20X +20Y . Market demands for the 2 goods are given by PX =80−X, and PY =140−2Y Suppose the government wished to use two part tariffs in these markets, and suppose further that two part tariffs are feasible. Imagine that there are 10 consumer in each market. Solve for a set of two part tariffs (one for each martket) that pay the firm zero profits in total, yet achieves efficiency.
Suppose you are the manager of a watchmaking firm operating in a competitive market. Your cost of production is given by C=400+2q2, where q is the level of output and C is total cost. (The marginal cost of production, MC(q), is 4q;the fixed cost, FC, is $400). If the price of a watch is $100, how many watches should you produce to maximize profits? You should produce______watches.(Enter your response as an integer.) What will the profit level be? Profit will be $___________. (Enteryour response rounded to two decimal places.) At what minimum price will the firm produce a positive output? In the short run, the firm will produce if price is greater than $__________ per watch. (Enter your response as an integer.
Road Runner Co is a Pakistani manufacturer making Bicycles. It exports to two markets,Bangladesh and Sri Lanka. Demand for Bicycles in thesetwo markets is given by the following Functions: Bangladesh Q1 = 12 – P1 Sri Lanka Q2 = 8 – P2 Where Q1 and Q2 are respective quantities sold (in thousands) andP1 and P2 are the respective prices (in Pak. Rupees per unit) in the two markets. Total cost function is C = 5 + 2 (Q1+ Q2) A.Determine the company’s total profit function. Also, (i) What are the profit maximizing levels of price and output for the two markets? (ii) Calculate the marginal revenues in each market. B.Now consider two cases: (i) Company is effectively able to price discriminate in thetwo markets. What will be the total profits? (ii) Suppose the company does not engage in price discrimination. By charging thesameprice in the two markets what are the profit maximizing levels of price,output, and the total profits?…
