Question 1

Why do convex indifference curve have a negative slope?

Accepted Answer

Convex indifference curves have a negative slope because to keep utility constant, a consumer must get more of one good if she is to give up some of the other. This is known as the diminishing marginal rate of substitution. As the consumer consumes more of one good (say, x), the marginal utility of that good decreases, and the consumer must receive more of the other good (say, y) to compensate for the decrease in satisfaction. This results in a negative slope, as the consumer is willing to give up some of good y for more of good x, but only up to a certain point. After a certain point, the consumer becomes less willing to give up more of y, resulting in a convex shape to the indifference curve.

Accepted Answer

A sunk cost is a cost that has already been paid and cannot be recovered, regardless of future actions or decisions.

Question 4

Some online penny auctions charge a fee,such as $1,for every bid placed.Why should these costs of $1 per bid be considered sunk costs? Would it be smart for someone who has "already invested $5 in bidding costs" to keep bidding to "protect his or her sunk investments"? Why or why not?

Accepted Answer

Question 5

The slope of the indifference curve is referred to as

Accepted Answer

The slope of the indifference curve represents the rate at which the consumer is willing to substitute one good for another while maintaining the same level of satisfaction. This is known as the Marginal Rate of Substitution (MRS).

Question 6

What does the marginal rate of substitution measure?

Accepted Answer

The marginal rate of substitution measures the rate at which a consumer is willing to trade off one product for another while keeping utility constant, meaning they are indifferent between two goods at their current consumption levels. This is often represented by the slope of the indifference curve.

Question 7

Why do many film processing companies have a policy of printing every picture on a roll of film or a memory card,even if the picture is very fuzzy and customers are allowed to ask for refunds on any pictures they do not like?

Accepted Answer

The answer of Why do many film processing companies have...

Question 8

In the utility maximizing model,consumer preferences are assumed to be transitive.What does this mean?

Accepted Answer

Transitivity means that if a consumer prefers option A to option B, and B to option C, then they also prefer option A to option C. This assumption is necessary for the utility maximizing model to be valid, as it allows us to make predictions about consumer behavior based on their stated preferences. Options A, B, and D do not directly relate to transitivity.

Question 9

A common mistake made by consumers is the failure to take into account the monetary costs of their actions.

Accepted Answer

The answer of A common mistake made by consumers is...

Question 10

A curve that shows combinations of consumption bundles that give a consumer the same utility is called

Accepted Answer

An indifference curve shows all the combinations of two goods that give a consumer the same level of satisfaction or utility, and the slope of the indifference curve represents the consumer's marginal rate of substitution between the two goods. Option A is incorrect because a utility curve is not a term commonly used in economics. Option C is incorrect because a preference curve is not a relevant concept in consumer theory. Option D is incorrect because a demand curve shows the quantity of a good consumers are willing and able to buy at different prices, and does not relate to the concept of utility.

Question 11

Vinny consumes tacos and chicken wings.To keep his utility constant,he must consume more tacos if he consumes fewer chicken wings.This means that

Accepted Answer

The negative slope of the indifference curve for tacos and chicken wings indicates that Vinny must give up some chicken wings to consume more tacos and still remain equally satisfied. This is the concept of marginal rate of substitution (MRS), which measures the rate at which a consumer is willing to exchange one good for another while keeping the same level of utility. A negative slope implies that Vinny must give up more and more chicken wings to consume additional tacos.

Question 12

Celebrity endorsements of products,such as Snoop Dogg's tweets about the Toyota Sienna minivan,are intended to cause the demand curve for the product to ________,which allows the product's manufacturer to ________.

Accepted Answer

Celebrity endorsements are intended to increase the demand for a product by increasing its perceived value. This shift in the demand curve to the right means that at every price, more of the product will be sold, allowing the manufacturer to sell more of the product and increase its revenue. However, it does not necessarily lower the production costs or increase the output.

Question 13

One reason college students do not study enough to get high grades is that they are unrealistic about their future behavior.

Accepted Answer

College students often have unrealistic expectations about how much time and effort they will need to put into studying in order to achieve high grades. They may overestimate their ability to cram for exams or complete assignments last minute, leading to subpar performance.

Question 14

Which of the following is held constant along an indifference curve?

Accepted Answer

The answer of Which of the following is held constant...

Question 15

Behavioral economists examine choices that consumers make that are not economically rational.Economists generally assume that people are rational; that is,they weigh the benefits and costs of an action and choose an action only if the benefits outweigh the costs.Why do consumers not act rationally when the result is that they make themselves worse off?

Accepted Answer

The answer of Behavioral economists examine choices that consumers make...

Question 16

Figure 10-2 
-Refer to Figure 10-2.Best friends Laurel and Hardy both enjoy watching romantic comedies and science fiction movies.Based on the diagrams above what can you conclude about their movie preferences?

Accepted Answer

Hardy's preference for science fiction movies is represented by a larger area than Laurel's, indicating that Hardy enjoys science fiction movies more than Laurel.

Question 17

Explain the endowment effect.

Accepted Answer

The answer of Explain the endowment effect....

Question 18

What happens to the absolute value of marginal rate of substitution as you move down a convex (bowed toward the origin)indifference curve?

Accepted Answer

The marginal rate of substitution (MRS) decreases as you move down a convex indifference curve. This is because the slope of the indifference curve (which represents the rate at which the consumer is willing to trade one good for the other) becomes flatter as you move down the curve. Since the MRS is the absolute value of the slope of the indifference curve, it also decreases.

Question 19

A consumer's budget constraint is

Accepted Answer

A consumer's budget constraint refers to the limited income or budget that the consumer has to allocate towards purchasing goods and services. It represents the trade-off between different goods and services that a consumer can afford to purchase given their income and the prices of goods in the market. Lower income or prices of goods will widen the budget constraint, while higher income or prices will narrow it.
