American Idle sells hammocks in a perfectly competitive market. This year, the price of hammocks has fallen to $27, and Simon Cowbell, the manager of American Idle, is trying to decide what to do. He discovers that his average variable cost (AVC) is $25, average total cost (ATC) is $30, and marginal cost is $27 and rising. What should he do? A) stay open because price > AVC B) shut down because p < ATC and the firm is making losses C) increase production until ATC falls below $27 D) lower the fixed cost so that ATC falls below $27 E) decrease production so that MC falls below $27
A) stay open because price > AVC
Due to the increased demand for ethanol and other bio-fuel energy alternatives, the United States Department of Agriculture (USDA) has predicted that American farmers are likely to receive 55 percent more for a bushel of corn in the 2006/2007 growing season than they recelved in the 2005/2006 growing season.

Durabattery Company has a plant located on the White River. It produces batteries and sells in the perfectly competitive market for batteries.

Suppose that in the construction industry that market equilibrium wage rate is $5 per hour. The government imposes a minimum wage of $6 per hour. Then A) the value of the marginal product would exceed the wage rate, and firms would hire more workers B) the firms would hire fewer workers at the minimum wage rate but the quantity supplied of labor will increase leading to unemployment (that is a surplus of workers) C) the firms would increase their prices to keep the marginal revenue product equal to the wage rate D) the firms would hire fewer workers at the minimum wage rate and the supply of labor would decrease causing the labor market to clear E) The firms would hire fewer workers as the value of the marginal products of the workers now has to be at least as much as $6 an hour

Henry sells tomatoes in the perfectly competitive Italian Market in Philadelphia. The market price for tomatoes is $2.75 per pound. In order to sell tomatoes, he has to buy them from the wholesaler and store them, until the market opens. Henry can buy the tomatoes from a wholesaler at $1.50 a pound but has found that the marginal cost of storing the tomatoes increases at the rate of 5 cents per pound (that is, the marginal cost of storing 1 pound of tomatoes is 5 cents, the marginal cost of storing 2 pounds is 10 cents, and so on) In order to maximize profits Henry should sell A) As many tomatoes as he can since the wholesale price is less than the market price B) The amount that has the lowest average cost after computing his total cost of buying and storing tomatoes C) 25 pounds of tomatoes because at this quantity, the price = marginal cost, and marginal cost is increasing D) At a price like $2.50 per pound since at such a price he will surely sell his entire stock of tomatoes as it is less than the market price
C) 25 pounds of tomatoes because at this quantity, the price = marginal cost, and marginal cost is increasing

In order to boost enrollment and improve retention at IUPUI, the City of Indianapolis is considering imposing a price ceiling of $500 for a one-bedroom apartment in the apartment complexes close to IUPUI. The monthly rental rate for a 1-bedroom in these apartment complexes is currently $700 per month.

Joe Garcia has opened a coffee shop that sells gourmet coffee and sandwiches. He employs two individuals on a part time basis and manages the shop himself. The wages for the two employees come to a total of $30,000 every year. He spends another $30,000 on materials for the shop.

The marginal cost of milk production at Dana's Dairy, at its current output, is $2.50 per gallon and is greater than the average variable cost. Dana's Dairy has the usual U-shaped marginal cost and average cost curves and it knows that its marginal cost will rise if it increases the output. Dana's Dairy A) is making an economic profit of $0.50 per gallon B) should charge $3.00 per gallon but continue to produce at its current level of output, since it is making a profit C) Should charge $2.50 per gallon to maximize profits D) should reduce its output of milk to where the average cost is at its minimum E) should increase its output of milk to the output at which the marginal cost is $3.00 to maximize profits
