Suppose that the seitan industry is initially operating in long-run equilibrium at a price level of $5 per pound of seitan and quantity of 175 million pounds per year. Suppose a top medical journal publishes research that animal-alternative protein sources such as seitan could increase your expected lifespan by 5 years. The publication is expected to cause consumers to demand (less/more) seitan at every price. In the short run, firms will respond by ( attached image). Shift the demand curve, the supply curve, or both on the following graph to illustrate these short-run effects of the publication In the long run, some firms will respond by (attached image) until (consumer demand returns to original level, each firm in the industry is once again earning zero profit, seitan populations grow large enough to support more firms, new technologies are discovered that lower costs) Now Shift the demand curve, the supply curve, or both on another graph (same as the first) to illustrate both…
Assume that the gold-mining industry is perfectly competitive. a) Illustrate a long-run equilibrium using diagrams for the gold market and for a representative gold mine. b) Suppose that an increase in jewelry demand induces a surge in the demand for gold. Using your diagrams, show what happens in the short run to the gold market and to each existing gold mine. c) If the demand for gold remains high, what would happen to the price over time? Specifically, would the new long-run equilibrium price be above, below, or equal to the short-run equilibrium price in part b)? Note:- Do not provide handwritten solution. Maintain accuracy and quality in your answer. Take care of plagiarism. Answer completely. You will get up vote for sure.
Suppose the market for corn is a purely competitive, constant-cost industry that is in long-run equilibrium. Now assume that an increase in consumer demand occurs. After all resulting adjustments have been completed, the new equilibrium price will be Multiple Choice the same as the initial equilibrium price, but the new industry output will be greater than the original output. greater than the initial price, and the new industry output will be greater than the original output. less than the initial price, but the new industry output will be greater than the original output. the same as the initial equilibrium price, and the industry output will remain unchanged.
Suppose there are 1,000 hot pretzel stands operating in New York City. Each stand has the usual U-shaped average-total-cost curve. The market demand curve for pretzels slopes downward and the market for pretzels is in long-run competitive equilibrium. Draw the current equilibrium, using graphs for the entire market and for an individual pretzel stand. Now the city decides to restrict the number of pretzel-stand licenses, reducing the number of stands to only 800. What effect will this action have on the market and on an individual stand that is still operating? Use graphs to illustrate your answer. Suppose that the city decides to charge a license fee for the 800 licenses. How will this affect the number of pretzels sold by an individual stand, and the stand’s profit? The city wants to raise as much revenue as possible and also wants to ensure that 800 pretzel stands remain in the city. By how much should the city increase the license fee? Show the answer on your graph.
If there were 60 firms in this market, the short-run equilibrium price of titanium would be $________ per kilogram. At that price, firms in this industry would (earn a positive profit, shut down, earn zero profit, operate at a loss). Therefore, in the long run, firms would ( enter, exit, neither enter nor exit) the titanium market. Because you know that perfectly competitive firms earn (positive, zero, negative) economic profit in the long run, you know the long-run equilibrium price must be $_______ per kilogram. From the graph, you can see that this means there will be (20, 40, 60) firms operating in the titanium industry in long-run equilibrium.
Consider the graphs of a constant cost industry and a perfectly competitive firm within it. Initially, the industry is in long‑run equilibrium at point E, then demand shifts from Demand1 to Demand2. Answer the questions where P is the price, MR is the marginal revenue, AR is the average revenue, MC is the marginal cost, SRATC is the short‑run average total cost, and LRAC is the long‑run average total cost. Manipulate both of the graphs to reflect the adjustments that yield the long‑run equilibrium.

In a purely competitive market at its long-run equilibrium, which of the following is not true? a The marginal benefit of the last unit of the product equals the marginal cost of producing that unit. b The maximum willingness of buyers to pay for the last unit of the product equals the minimum acceptable price for the seller of that unit. c Price equals marginal cost, and they are equal to the lowest attainable average cost of production. d The combined amount of consumer and producer surpluses is at its minimum possible.
Assume that a firm in a perfectly competitive industry has the following total cost schedule: Calculate a marginal cost and an average cost schedule for the firm to complete the following table. Output Total Cost Marginal Cost Average Cost (units) ($) ($) ($) 10 440 15 600 20 720 25 900 30 1,200 35 1,540 40 1,920 If the prevailing market price is $68 per unit, units will be produced. Profits per unit will be and total profits will be . Is the industry in long-run equilibrium at this price? No Yes
The table below shows the average cost (AC) for a purely competitive market. The average revenue (AR) is constant at RM5 per unit and the firm’s total fixed cost (TFC) is RM4. If the average revenue falls to RM3 per unit, calculate the firm’s new profit or loss at the equilibrium. Based on your answer, should the firm continue or stop the production? Justify. Output (Units) Total Revenue (RM) Average Cost (RM) Total Cost (RM) Marginal Cost (RM) Marginal Revenue (RM) 1 8.0 2 5.5 3 4.0 4 3.5 5 3.8 6 4.5 7 6.0

Currently, there are 9 firms in the market What is each firm’s fixed cost? What is its variable cost? At what quantity efficiency of scale would be achieved? Give the equation for each firm’s supply curve Give the equation for the market supply curve for the short run What is the equilibrium price and quantity for this market in the short run? In this equilibrium, how much does each firm produce? Is there incentive for firms to enter or exit? In the long run with free entry and exit, what is the equilibrium price and quantity in this market? In the long-run equilibrium, how many firms are in the market?
