Modified True or False: State whether each statement is true or false. If the statement is false, briefly explain why it is so, and then restate it to make it true. In the long-run competitive equilibrium, price, short-run marginal cost, short-run average cost, and long-run average cost are all equal, and economic profits are zero.

Modified True or False: State whether each statement is true or false. If the statement is false, briefly explain why it is so, and then restate it to make it true. i. In the long-run competitive equilibrium, each individual firm chooses a scale of operations that minimizes its long-run average cost.
Q17 Assume that the cannabis firm called Aphria Inc. purchases resources a and b under perfectly competitive conditions and combines these resources to produce marijuana. Assume marijuana is sold in a perfectly competitive market. The MPs of a and b are 12 and 6, respectively, and the prices of a and b are $6 and $3, respectively. If profit-maximizing equilibrium exists, the price of marijuana will be Multiple Choice $0.50. $2. $6.67. $5. $1.

Lower equilibrium price and greater equilibrium quantity. B. Higher equilibrium price and smaller equilibrium quantity. C. Lower equilibrium price and smaller equilibrium quantity. D. Higher equilibrium price and greater equilibrium quantity.
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.
Suppose that the perfectly competitive market for wheat spaghetti is in long-run equilibrium. Suppose also that campaigns for fighting obesity make students on lots of college campuses in the US aware of the fact that excessive pasta (including spaghetti) consumption has an adverse effect on body weight, and these campaigns provide an incentive for students to restrict spaghetti consumption. How do the campaigns described above affect the market for wheat spaghetti in the US, that is does the supply or the demand curve for wheat spaghetti shift and in what direction? How are the equilibrium price and quantity of wheat spaghetti affected in the short run? What happens to the short-run profit of the typical producer of wheat spaghetti in the US? What will be the price of wheat spaghetti in the long run? What profit will producers of wheat spaghetti make in the long run? Explain how this outcome is achieved. Use two graphs: one showing the market supply and demand curves for wheat…
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.
please answer question 11 and 12 and 13 11- the market price for the product is $29. If company A wants to maximize its profits and sells in a purely competitive market, how many should they produce? 12- using the price given in Q 11, will company A make an economic profit or economic loss? Show your calculation 13- given the economic profit/loss calculate in Q12, will firms enter or leave this industry or is this industry at long run equilibrium? Why?

Determine whether each of the statement is true, false, or uncertain. If the statement is false or uncertain, please correct the statement to make it true. If the statement is true, please explain your answer briefly. Give a brief definition of any underlined term. a. In the long run equilibrium of a competitive market, all firms are earning normal profits and operating at the efficient scale. b. The competitive firm’s supply curve is upward sloping and its demand curve is downward sloping.
A perfectly competitive firm sells its good for $20. If marginal cost is four times the quantity produced, how much does the firm produce? Why? Assuming perfect competition, there is not enough information to determine how much the firm is producing. Assuming perfect competition, the firm is producing where MC is twice MR. If the price is $20, then MC is $40. This means that the firm is producing 10 units. Assuming perfect competition, the firm is producing where MR = MC. If the price is $20 and MC is four times the quantity, it is producing 80 units. Assuming perfect competition, the firm is producing where MR = MC = P. Since price is $20, MR is $20. If MC is 4 times the quantity, it is producing 5 units.
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.
Answer both parts a and b please. Part a) True or False: In a competetive market, a firm's short run supply curve is sloping upwards due to diminishing returns of the variable input. Explain why. Part b) Are long run supply curves always upward sloping? Explain why or why not with a graph.
