a. In the long-run in a decreasing-cost competitive industry, HD EDU's long-run supply curve is horizon- tal at the minimum of its ATC; the industry-supply curve is downward sloping. b. In the long-run in a decreasing-cost competitive industry, HD EDU's supply curve is its marginal cost (MC) curve above the minimum of average total cost (ATC); the industry supply curve is the horizon- tal summation of the marginal cost curves of HD EDUs in the industry above the minimum of their respective average total cost curve (ATC). c. In the long-run in a competitive constant-cost industry, HD EDU's supply curve is its MC curve above the minimum of ATC (average total cost); the industry supply curve in this constant-cost industry is perfectly elastic at the minimum of ATC. d. In the long-run in a constant cost industry, the supply curve of a competitive firm is perfectly elastic at the minimum of ATC; the long-run industry supply curve in this constant-cost industry is perfectly elastic at the minimum of AFC (average fixed cost). e. None of the above. Which statement is correct? Why the rest of the answers are incorrect?

The canola farming industry is perfectly competitive. Assume that it is in long-run equilibrium at quantity Q0 and price P0. Assume also that it is a constant-cost industry. a) Draw a supply and demand diagram for the canola market showing this equilibrium b.) draw diagram for a typical canola growing farm in its initial long run equilibrium, showing its Marginal Cost, Average Total Cost, and Long Run Average Cost curves. Are there any profits being made by this firm?
1) On a graph for a representative firm in a perfectly competitive industry, depict the three cost curves AVC, ATC, and MC (assume typical U-shaped cost curves). Now assume the market price, P, is such that it intersects the upward-sloping portion of MC above ATC. Graphically depict the short-run equilibrium q (representative firm's output) and π (representative firm's profit) under this price scenario. 2) Given the situation you graphically depicted in #1, please state the level of economic profits (positive, zero, negative) of this representative firm and explain why this is the case.
In a competitive market characterized by increasing costs, the long-run industry supply curve gives the minimum long-run average cost of production at various levels of industry output. long-run industry supply curve gives the long-run marginal cost of production at various levels of industry output. long-run industry supply curve is upward sloping. both a and b all of the above
an inward shift of the demand curve in the competitive market for paper clips. Using fully labeled, side-by-side graphs for the market and the (typical) firm, show what happens (at both the market and firm level) in the short run and long run. In the firm-level graph, be sure to draw a plausible MC and ATC curve for the firm. Show and label any economic profits or losses. You can show both the short run and long run effects on the same pair of graphs.
A perfectly competitive industry consists of many identical firms, each with a long-run total cost function of TC = 500Q-20Q^2+0.5Q^3. a. In long-run equilibrium, how much will each firm produce? b. What is the long-run equilibrium price? c. The industry's demand curve is ?? = 48,000 − 60?. How many firms are in the I ndustry? d. If the industry demand decreases to ?? = 30,000 − 80? how will the industry respond?
13. Suppose a representative firm in a perfectly competitive industry has the following totalcost of production in the short run: TC=Q^3-40Q^2+600Q.a. What will be the long run equilibrium quantity for the firm? What will be the longrun equilibrium price in this industry?b. Let the industry demand be given by QD=12400-4P. How many firms will be activein the long-run equilibrium?c. Suppose the firm faces a positive demand shock that increases the industry demandto QD=16000-4P. Describe how the industry would respond and calculate thechange in the number of firms.
(a) Let the industry producing soybeans be in a long-run equilibrium. What is the equilibrium price of a bushel of soybeans? How many billions of bushels are produced? How many farmers are there in the industry? What is the shipping fee per bushel of soybeans? (b) Suppose that the demand for soybeans drops due to decreased im- port by China and becomes Q = 15.3 − p. In a new long run equilibrium, what is the equilibrium price of a bushel of soybeans? How many billions of bushels are produced? How many farmers are there in the industry? What is the shipping fee per bushel? (c) Calculate the change in the producers’ surplus between the situations described in (a) and (b). (d) Show that the decrease in the producers’ surplus equals to the decrease in the total shipping fees as the industry contracts incrementally from the equilibrium output in (a) to the equilibrium output in (b).
