Principles Of Economics 5th Edition By Frank – Test Bank

1. Adam Smith’s invisible hand leads to an efficient outcome when

1. buyers are fully informed about all relevant aspects of the product and the market in which it is traded.

B buyers have collected information only up to the point at which the marginal cost of acquiring more

.  information equals the marginal benefit of having more information.

1. buyers have more information about the product being traded than do sellers.
2. buyers have less information about the product being traded than do sellers.

4. Sydney sells snow globes from a cart. When the cart is located on the sidewalk near a discount store, Sydney’s customers have reservation prices of $5. When Sydney’s cart is located on a sidewalk in

an upscale mall, wealthier customers with reservation prices of $10 buy snow globes. Assume that Sydney can sell the same volume at either location and that marginal and average costs are $3 per globe at both locations.

Maximization of total economic surplus indicates that Sydney should

1. alternate between the two locations and price discriminate.

5. sell only near the discount store and charge $5.

10. sell only in the upscale mall and charge $10.

1. alternate between the two locations and charge $5 at both locations.

5. Sydney sells snow globes from a cart. When the cart is located on the sidewalk near a discount store, Sydney’s customers have reservation prices of $5. When Sydney’s cart is located on a sidewalk in

an upscale mall, wealthier customers with reservation prices of $10 buy snow globes. Assume that Sydney can sell the same volume at either location and that marginal and average costs are $3 per globe at both locations.

Information about the reservation prices of Sydney’s customers increases total surplus by

1. allowing consumers with different incomes to acquire things they value.

1. distributing snow globes to consumers who like them most.

1. encouraging sellers to locate in underserved areas.
2. distributing snow globes to consumers with the greatest willingness to pay.

6. Better information about consumers’ reservation prices generally leads to
   1. a reduction in consumer surplus.

1. acquisition of goods by consumers who are willing to pay the highest price.

1. equitable distribution of goods among low income consumers.
2. acquisition of goods by consumers with the greatest need.

7. When auctions, such as those used on eBay, are used to sell a product
   1. information about consumers’ true reservation prices is minimized.

1. information about consumers’ true reservation prices is revealed.

1. consumers have an incentive to bid higher than their true reservation prices.
2. consumers do not have an incentive to bid their true reservation prices.

8. Jean places a high value on a loaf of bread with which to feed his family, but can only afford to pay $1. Val regularly pays $2 for a loaf of bread, but often the bread molds before Val can finish the loaf. Total economic surplus is maximized when

1. Jean receives a loaf of bread.

1. Val gives Jean leftover bread.

1. Val purchases the bread.

1. Val and Jean purchase equal quantities of bread.

9. The optimal amount of information to acquire before making a purchase is

1. as much as technically possible.

1. an amount such that the total cost of acquiring information equals the total benefit.

1. an amount such that the marginal cost of acquiring information equals the marginal benefit.

Difficulty: 1 Easy Frank – Chapter 11 #9 Learning Objective: 11-02 Use the concept of rational search to find the optimal amount of information market participants should obtain.

10. The reason the marginal benefit of information curve is downward sloping is because
    1. some information is useless.
    2. most information is useless.

1. information is subject to the law of diminishing marginal returns.

1. there is only so much to learn about a product.
