Unformatted text preview: Name: Class: Date: ID: A ECO 3033 Sample Objective Questions, Exam 1. TruetFalse Indicate whether the sentence or statement is true orfalse. 1. HM HM NM In is. E‘ £ 10. The marginal product of a variable input is unrelated to the marginal cost of additional output that the input could produce. Total variable cost is the inverse of total product. Implicit costs are those costs of production for which specific payment has been made sometime in the past or for which the firm is committed in the future. Variable costs are costs that increase or decrease as a firm's output increases or decreases. The social costs of firm are the private costs of the resources that the firm uses plus any additional costs imposed on society by the firm's operations. Average fixed cost is equal to total fixed costs divided by the level of output. The demand function for a firm relates the quantities of a product or service that consumers would like to purchase during some specific period to the variables which influence consumer decisions to buy the good or service. Marginal revenue is the rate of change of total revenue with respect to price. If the cross elasticity of demand of good X for changes in the price of good Y is negative, the two goods are complements. A firm determines that the own price elasticity of demand for its brand of a product is negative. Thus, it knows that demand is inelastic. Multiple Choice Identify the letter of the choice that best completes the statement or answers the question. L 11. 8 12. The price ofa firm's product times the quantity demanded of that product is: marginal revenue. the firm's demand curve. total revenue. price elasticity of demand. average revenue. she-99’s Which of the following statements regarding arc elasticities is FALSE? The arc elasticity approximates point elasticity. Arc elasticities do not measure responsiveness; only point elasticities do this. Are elasticities do NOT use derivatives in their calculations. Arc elasticities are elasticities calculated between two points or two values of a variable. The are elasticity refers to the average responsiveness of Q. 99.057?” Name: ID: A _Q 13. Ifthe absolute value of the price elasticity of demand is less than 1, then: a an increase in price decreases total revenue. b an increase in price has no affect on total revenue. 0. a decrease in price lowers total revenue. d a decrease in price raises total revenue. e a change in price has no affect on total revenue. A 14. If the value of the cross price elasticity of demand of good X for a change in good Y's price is less than 0, then: a. the goods are complementary. b. the goods are substitutes. c. demand is said to be inelastic. d. the goods are superior goods. e. demand is said to be elastic. fi 15. Long-run marginal cost: is the rate of change of long-run fixed cost as the level of output changes. is the rate of change of long-run total cost as the level of output changes. is always constant. is usually fixed over a given range of production. is the rate of change of long-run average cost as the level of output changes. E 16. Short-run marginal cost: a is the rate of change of short-run fixed cost as the level of output changes. b is the rate of change of short-run total variable cost as the level of output changes. c. is the rate of change of short-run total cost as the level of output changes. d e 9999‘!» is the rate of change of short-run average cost as the level of output changes. b and c C 17. Which of the following are implicit costs for a typical firm? insurance costs electricity costs opportunity costs of capital owned and used by the firm cost of labor hired by the firm the cost of raw materials 99.0.6!» 5 13. Accounting profit equals explicit costs minus implicit costs economic profit minus implicit costs economic profit minus explicit costs economic profit minus explicit costs and implicit costs economic profit plus implicit costs A 19. Which of the following 15 most likely to be a fixed resource for the City Slicker‘ s Dude Ranch? (”P-953‘!“ a. the lodge where the guests stay 13. food for the guests c. stable hands to take care of the horses d. hay for the horses e. water for the horses Name: ID: A _ Numeric ReSponse 20.

Level-Mow currently sells 1200 units per month at a current price of$1,900. a. Its main competitor, Super-Cut, Inc. has just lowered the selling price of its comparable model from $1,000 to $800. Ifthe arc cross price elasticity of demand between the two mowers is .818 over the range of the proposed price cuts, then what will be the new quantity of lawnmowers sold by Level-Mow, Inc.? b. Assume that Super-Cut, Inc. has completed its price reduction mentioned in part a above. If Leve1~Mow now wants to counter Super-Cut's price reduction with one of its own, then to what price must Level-Mow go in order to return to its original volume of 1200 units?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
