Ben opened his ice cream stand and he aims to maximize profits by making 100 ice cream cones a day. Ben planned to buy two ice cream makers, but his sister happened to have an extra one and she gave it to him for free. Ben's fixed costs decrease and the market price remains constant. The short run profit maximizing level of output a day a) becomes zero b) is still 100 ice cream cones c) is more than 100 ice cream cones d) is less than 100 ice cream cones

Consider a competitive firm with total costs given by T C(q) = 100 + 10q + q^2. The firm faces a market price p = 50. (a) Graph the AT C, AV C, MC, and MR curves in a single graph, and indicate the profit maximizing level of output. If there are profits, shade the region corresponding to profit and label it. (b) If fixed costs increase from 100 to 500, what happens to the profit maximizing level of output, T R, T C, and π? (c) If fixed costs increase from 100 to 500, should the firm continue to operate in the short-run? What about the long-run?

The following graph illustrates the demand and marginal revenue curve (D-MR) of a perfectly competitive firm. Suppose that when the firm produces 40 units, its average variable cost equals $65 per unit and its average total cost equals $80 per unit. Use the green rectangle (triangle symbols) to plot the total cost of producing 40 units. Next, use the grey rectangle (star symbols) to plot the total variable cost of producing 40 units. Then, use the tan rectangle (dash symbols) to plot the total revenue at 40 units. Finally, use the purple rectangle (diamond symbols) to plot the profit or loss at 40 units.

The graphs suggest that in the long run, assuming no changes in the given information,
Suppose that you have a management job at a firm like Estrella River Ranch, a beautiful vineyard and one of more than 200 vineyards growing cabernet sauvignon grapes in California. Assume that the market is perfectly competitive. Also, assume that you cannot instantly change production when demand changes, and grapes cannot be stored, so your firm must sell all of the grapes it grows. The adjacent figure (Figure A) shows the situation at your California vineyard. If demand is high, the price is $3,000 per ton of grapes, and if the price is low, the price is $1,000 per ton of grapes. Producing 300 tons of grapes maximizes your firm's expected profit. Suppose that there is no fixed cost. If demand is high and your firm produces 300 tons of grapes, its economic profit on the tons of grapes between 100 and 300 tons is $ If demand is low and your firm produces 300 tons of grapes, its economic loss on the tons of grapes between 100 and 300 tons is dollars.
