MCQ 7
A firm is considering whether to adjust the price it charges for units of output, but it first needs to know how the quantity of output sold and total revenue will be affected.
The firm employs a statistician to examine the structure of demand and she estimates that the price elasticity of demand for the firm's product lies somewhere between -
0.25 and -0.75. If this estimate is correct, we can deduce that:
A
an increase in price will generate a reduction in the quantity of output sold and a fall in total revenue
a reduction in price will generate an increase in the quantity of output sold and a rise in total revenue
an increase in price will generate a reduction in the quantity of output sold, but the uncertainty connected with the estimate of price elasticity implies that it is
C
not possible to determine whether total revenue will rise or fall
D
a reduction in price will generate an increase in the quantity of output sold and a fall in total revenue
E
a reduction in price will…
How does the speed of a runner vary over the course of a marathon (a distance of 42.195 km)? Consider determining both the time to run the first 5 km and the time to run between the 35-km and 40-km points, and then subtracting the former time from the latter time. A positive value of this difference corresponds to a runner slowing down toward the end of the race. The accompanying histogram is based on times of runners who participated in several different Japanese marathons (“Factors AffectingRunners' Marathon Performance,” Chance, Fall, 1993: 24-30).
What are some interesting features of this histogram? What is a typical difference value? Roughly what proportion of the runners ran the late distance more quickly than the early distance?
Histogram for Exercise 22
a) For each, find the expressions for marginal utilities and the marginal rate of substitution, and
determine whether monotonicity and convexity are met.
