A friend has just started up her own business. Her firm asks you how much to charge for her product to maximize profits. The demand schedule for it is given by the first two columns in the table below; its total costs are given in the third column. For each level of output, you can calculate total revenue, marginal revenue, average cost, and marginal cost. The profit-maximizing level of output can be found at the point where TR - TC is greatest, or where MR = MC, (or the last quantity where MR is still greater than MC.)
What is the profit-maximizing level of output for her product? 40
How much will she earn in profits? 80
Price Quantity TC TR? MR? MC?

Suppose that Tommy Hilfiger's marginal cost of a jacket is a constant $100 and at one of the firm's shops, total fixed
cost is $2,000 a day.
The profit-maximizing number of jackets sold in this shop is 20 a day.
When the shops nearby start to advertise their jackets, this Tommy Hilfiger shop spends $2,000 a day advertising
its jackets, and its profit-maximizing number of jackets sold jumps to 50 a day.
What happens to Tommy's markup and its economic profit? Why?
Tommy's markup
A. rises, falls, or remains unchanged depending on the effect of advertising on demand
OB. falls because advertising decreases demand
OC. rises because advertising increases demand
OD. does not change because advertising is generally ineffective

In the short run, Tommy's economic profit

- Narasimhan is accelerating the rollout of new equipment that will make it easier for baristas to prepare complicated drinks. Question 1: Draw a graph with MC, ATC, and downward sloping demand curve. Be sure to identify all intersections, equilibrium points, and labels. Show on this graph what Narasimham expects to happen as a result of introducing new equipment for drink preparation. Be sure to include a one paragraph explanation of how the graph will be affected and the expected result of this change. The article also states that: The company plans to introduce new boba-inspired drinks and food items to attract weekend customers. It is looking to tap into late-night and overnight demand.arrow_forwardA profit-maximising firm faces a downward-sloping demand curve for its output and has marginal costs that increase with output. Explain why a single firm might face downward-sloping demand. Explain why, as Q increases, marginal revenue will decline more quickly than demand. Illustrate this with a sketch. Add marginal cost to your sketch and show the point of profit maximisation. The firm’s demand function is P = 100 - ½Q. Find its marginal revenue function. The firm’s cost function is C = 400 + Q + ¼Q2. Find its marginal cost function. Hence find the firm’s profit-maximising level of production. Now assume the firm is a typical firm in a perfectly competitive market. Explain why Q would be higher. Show in your sketch where there is an efficiency gain over the situation in part (b). Assume an initial equilibrium in which the firm in part (b) is earning excess profits. Explain how this excess profit will be reduced to normal profit, in the long run. Use your diagram in your explanation.arrow_forwardTomas is the general manager for a local automated car wash. The market he operates is perfectly competitive: Every car wash in the area is charging $7 for a car wash, which is also the marginal cost per wash.
