O. Option 1: shifts the demand curve out and increases the price. O. Option 2: shifts the supply curve up and increases the price O. Option 2: it shifts the demand curve up and increases the quantity. O. Option 2: shifts the supply curve up and increases the quantity.
Microsoft is the only business that sells Computer Operation System in the world. Assuming that Microsoft is maximizing its profit, which of the following statements is true? Select one : O a. Microsoft prices will be less than marginal cost. O b. Microsott prices will equal marginal cost. O c. Microsoft prices wil be a function of supply and demand and will therefore oscillate around marginal costs. O d. Microsoft prices will be higher than marginal cost.
. A firm in a perfectly competitive industry currently faces a market price of $20 and is maximizing profit by producing 500 units of output at this price. The firm’s total costs are $14,000, of which $5,000 are fixed costs. a) How much profit is the firm making? (Show how you determine this.) b) Should the firm continue to produce in the short run? Explain fully. c) Should the firm continue to produce in the long run? Explain clearly WHY the long run decision may be different than the short run decision, assuming the firm expects no changes in demand conditions.
Quantity Price 0 20 1 18 2 16 3 14 4 12 5 10 Are the price and quantity combinations above for a perfectly competitive industry? Select one: O a. No, they are not because the demand curve should be perfectly elastic. O b. No, because the quantities are too low. O c. Yes, they are because the demand curve is downward sloping. O d. Yes, they are because the price falls the same amount for each increase in quantity. Note:- Do not provide handwritten solution. Maintain accuracy and quality in your answer. Take care of plagiarism.

Question 3 The current market price in a competitive industry is $15. Every firm in the industry operates a technology that implies costs described by the function C = 12.5 + 0.3Q2. In the future, the technology is expected to change, and the new cost function will then be C = 10 + 0.2Q2. How much profit is the typical firm making today and in the long run? O. Profit is zero both today and in the long run. O. Profit is 125 both today and in the long run. O. Profit is 175 today and zero in the long run. O. Profit is 250 today and 125 in the long run.
a) Find the long run equilibrium price. Find the minimum efficient scale of the typical firm. Find the typical firm’s average cost when it operates at minimum efficient scale. In the long run, what price will prevail in this market? In words, clearly justify your answer. Suppose demand is QD = 3,200 – 100P. (b) Explain why you expect the number of firms in this market to be fifty-five. In this market, what is the short run supply function of the typical firm? What is the short run market supply function? Suppose the local government introduced a $90 licensing fee that raised the fixed cost from $160 to $250. c) Would the introduction of the licensing fee affect the short run equilibrium price or quantity? Justify your answer? Clearly explain why you expect that in the long run fewer larger firms will operate in this market. After the introduction of the licensing fee, what is the new long run equilibrium price? How many firms will survive in this market?
A small firm operating in a purely competitive market has fixed costs of $45 per day compensates each employee $96 per day and has daily input and raw material costs as indicated in the table below. A. What would be the profit maximizing level of production if demand increased such that each unit sold for $130?, will the company make an economic profit producing this quantity of output? b: suppose the demand significantly decreased so that price for a unit of ouput sold to $115 each. What should the firm do? Why?
What is the firm’s total variable cost at this level of output? $ e. What is the firm’s fixed cost at this level of output? $ f. What is the firm’s profit if it produces this level of output?

Instructions: If the firm is taking a loss, enter this as negative (−) profits. $ h. In the short run, should this firm continue to operate or shut down?
E3 Consider a perfectly competitive firm in a short run scenario. Its total cost function is TC(q)= 4q^2 + 8. The market demand function is Q(p) = 800 - 15p, and there are 40 identical firms in the market. A. What is a firm's short-run supply function? Will it ever decide to shut down? Explain. And what is the market supply function? B. Suppose there are 40 identical firms in the market. What is the equilibrium price, p*? What is the equilibrium quantity supplied by each firm, q*? What is each firm's equilibrium profit? Will there be more entry into the market? Why? C. Repeat b, but with 80 firms this time. Label your results with superscript ** D. Repeat part b, but with 280 identical firms now. Label your results by superscript ***. Part E. Compare your results in parts b - d. Explain why the increase in the number of firms affects the results in that manner. What should happen to profit eventually as the number of firms keeps increasing? And when this happens to profit,…
a. Are the following statements true or false? Explain your reasons. For a firm with price in excess of average total cost, the presence of economic profits implies that the firm should increase output in the short run even if price is below marginal cost. If marginal cost is rising with increasing output, average cost must also be rising. Fixed cost is the same at each output level except when no output is produced. When a firm produces no output, there are no fixed costs. b. Allsmart’s demand curve is given by Q=10-P for its dishwashers. The marginal and average cost is $3 per dishwasher produced. Complete the following table.
