QUESTION 3

1. Refer to the above table. Suppose that demand is represented by columns (3) and (2) and supply is represented by columns (3) and (5). If the price were artificially set at \$6,

 the market would clear. a surplus of 40 units would occur. a shortage of 40 units would occur. demand would change from columns (3) and (2) to columns (3) and (1).

QUESTION 4

1. A market is in equilibrium:
 provided there is no surplus of the product. at all prices above that shown by the intersection of the supply and demand curves. if the amount producers want to sell is equal to the amount consumers want to buy. whenever the demand curve is downsloping and the supply curve is upsloping.

 \$30. \$60. \$40. \$20.

QUESTION 6

1. Refer to the above diagram. If this is a competitive market, price and quantity will move toward:

 \$60 and 100, respectively. \$60 and 200, respectively. \$40 and 150, respectively. \$20 and 150, respectively.

4 points

QUESTION 7

1. Refer to the above diagram, which shows demand and supply conditions in the competitive market for product X. If supply is S1 and demand D0, then

 at any price above 0G a shortage would occur. 0F represents a price that would result in a surplus of AC. a surplus of GH would occur. 0F represents a price that would result in a shortage of AC.

QUESTION 8

1. (Last Word) A market-based system of buying and selling human organs for transplant would:
 reduce total health care spending. create a surplus of organs. increase the quantity of organs available for transplant. reduce the price of organs.

QUESTION 9

1. The basic formula for the price elasticity of demand coefficient is:
 absolute decline in quantity demanded/absolute increase in price. percentage change in quantity demanded/percentage change in price. absolute decline in price/absolute increase in quantity demanded. percentage change in price/percentage change in quantity demanded.

4 points

QUESTION 10

1. The demand for a product is inelastic with respect to price if:
 consumers are largely unresponsive to a per unit price change. the elasticity coefficient is greater than 1. a drop in price is accompanied by a decrease in the quantity demanded. a drop in price is accompanied by an increase in the quantity demanded.

4 points

QUESTION 11

1. Which of the following is notcharacteristic of the demand for a commodity that is elastic?
 The relative change in quantity demanded is greater than the relative change in price. Buyers are relatively sensitive to price changes. Total revenue declines if price is increased. The elasticity coefficient is less than one.

4 points

QUESTION 12

1. Suppose the price elasticity coefficients of demand are 1.43, 0.67, 1.11, and 0.29 for products W, X, Y, and Z respectively. A 1 percent decrease in price will increase total revenue in the case(s) of:
 W and Y. Y and Z. X and Z. Z and W.

QUESTION 13

1. Gigantic State University raises tuition for the purpose of increasing its revenue so that more faculty can be hired. GSU is assuming that the demand for education at GSU is:
 decreasing. relatively elastic. perfectly elastic. relatively inelastic.

4 points

QUESTION 14

1. The demand schedules for such products as eggs, bread, and electricity tend to be:
 perfectly price elastic. of unit price elasticity. relatively price inelastic. relatively price elastic.

4 points

QUESTION 15

1. The above diagram concerns supply adjustments to an increase in demand (D1to D2) in the immediate market period, the short run, and the long run. On the basis of this illustration we can conclude that:

 short-run adjustments are more economically efficient than are long-run adjustments. the amount of time producers have to adjust to a change in demand is not a determinant of supply elasticity. supply is more elastic the greater the amount of time producers have to adjust to a change in demand. supply is less elastic the greater the amount of time producers have to adjust to a change in demand.

QUESTION 16

1. (Consider This) Elasticity can be thought of as degree of relative:
 video brightness. price bounce. audio volume. quantity stretch.

QUESTION 17

1. Which of the following statements concerning the relationships between total product (TP), average product (AP), and marginal product (MP) is notcorrect?
 AP continues to rise so long as TP is rising. AP reaches a maximum before TP reaches a maximum. TP reaches a maximum when the MP of the variable input becomes zero. MP cuts AP at the maximum AP.
