1. Suppose a perfectly competitive firm has a cost function described by TC = 200Q+Q² +225 Each firm's marginal revenue is $240. a. Find the profit maximizing level of output. b. Is this a short-run or long-run situation? How do you know? c. Assuming that this firm's total cost curve is the same as all other producers, find the long-run price for this good.
2. Consider a competitive market where there are two types of firms, Type A and Type B, with total cost functions TC(q) = 2+4q+q² TCB (q) = 8+4q+6q² (a) Derive the short-run supply curve for each firm type (b) What is the short-run market supply, if there are 6 Type A firms, and 12 Type B firms? What is total quantity produced when p=10? (d) How does your answer at (c) change if we consider long run supply rather than short run? Here, assume again that p=10 and that there are 6 Type A firms and 12 Type B firms.
Course: Microeconomics A given firm, which is part of a perfectly competitive market, would have following cost function: TCLR = 2X3 - 20X2 + 200XWhat will be its level of output (X) and long-run equilibrium price (P)? NOTE: TCLR is long run total cost function

Suppose imposition of maximum price legislation reduced the price oil from the equilibrium price to the maximum price control price. Calculate: Price elasticity of demand Price elasticity of supply i. ii. e. From your calculation, which of the two curves is more elastic? Explain your answer.
11. Calculating %age Exx *3* When the price of product "X" increases 15 percent (+15%), the quantity demanded of "X" decreases 12 percent (-12%). The price elasticity of demand for "X" is: O "-1.25" and the demand for "X" is "relatively inelastic." "-1.25" and the demand for "X" is "relatively elastic." O "-1.25" and "X" is a "normal" good. O "-0.80" and the demand for "X" is "relatively elastic." O "-0.80" and the demand for "X" is "relatively inelastic." Save & Continue Continue without saving

Question Suppose firm VACC produces in a (perfectly) competitive industry and has the cost function C = 300 + 2q^2 + 15q where q is its output level. a) What are VACC's marginal cost? b) How much output will VACC produce for a price P = 115? c) Compute VACC's profits. d) What is the difference between a firm's profits and producer surplus ? (Can you give an intuition for the concept of producer surplus ?) e) What is VACC's producer surplus ?
1. Assume a competitive firm with a cost function c(y) = y? + 10 for y > 0 and with c(0) = 0. • In a competitive market, what is the lowest price at which the firm will supply a positive quantity in long-run equilibrium?
Looking to see how to resolve
4) Explain why a firm should continue to operate in the short run so long as market price is greater the firm's average variable cost at the profit-maximizing level of output.
2. Consider a market with 90 firms, each firm has a short-run total cost function as follows: TC(q) = 5q2, and a marginal cost function: MC(q) = 10q. Market demand is given by equation Qd(p) = 200 - p. a. What is the fixed cost? Solve the average variable cost function in the short-run. b. What is the supply function of each firm? c. Solve for the short-run equilibrium outcome: P*, Q* and q*. d. What is one firm's economic profit in this market? e. Consider a different market structure, where there is only one firm, interpreted as a monopolist, and then critically discuss the impact on equilibrium price and quantity. Discuss total surplus for these two types of market structures.
