Question 3

The demand curve for an inferior good can never be downward sloping.

Accepted Answer

The demand curve for an inferior good can be downward sloping. An inferior good is a good whose demand decreases when consumer income increases. As income increases, consumers switch to superior goods, leading to a decrease in demand for the inferior good. This can be represented by a downward sloping demand curve.

Question 4

Along a downward-sloping linear demand curve

Accepted Answer

Along a downward-sloping linear demand curve, the marginal utility from the consumption of each unit of the good falls and the total utility from consuming larger quantities increases. This is because as more units of the good are consumed, the marginal utility of each additional unit decreases, but the overall total utility still increases as more units are consumed.

Question 5

The demand curve for a luxury good is upward sloping.

Accepted Answer

The demand curve for a luxury good is typically downward sloping, like most goods, because as the price decreases, the quantity demanded generally increases. However, certain luxury goods may exhibit a Veblen effect, where higher prices can lead to higher demand due to perceived exclusivity, but this is not the norm for all luxury goods.

Question 6

The demand curve for a Giffen good is

Accepted Answer

A Giffen good is a product that people consume more of as the price rises, violating the basic law of demand, hence its demand curve is upward sloping.

Question 7

Each price-quantity combination on a consumer's demand curve shows the utility-maximizing quantity at the given price.

Accepted Answer

This statement is true. A consumer's demand curve shows the various quantities of a good or service that the consumer is willing and able to purchase at different prices. Each point on the demand curve represents the utility-maximizing quantity that the consumer would choose to buy at that particular price.

Question 8

The only Giffen goods that have been identified so far in the real world are luxury goods.

Accepted Answer

The only known examples of Giffen goods in the real world have been staple goods, like potatoes or rice, often found in poor households where a sudden increase in their price leaves less money for other necessities, leading people to paradoxically purchase more of the staple good as its price continues to rise. Luxury goods have not been identified as Giffen goods.

Question 10

Figure 10-2
  
Figure 10-2 represents the demand for ice cream cones.
-Refer to Figure 10-2.When the price of ice cream cones increases from $2 to $3, quantity demanded decreases from 4 ice cream cones to 3 ice cream cones.This change in quantity demanded is due to

Accepted Answer

The decrease in quantity demanded when the price increases indicates a substitution effect, where consumers switch to a lower-priced alternative good. This is consistent with the law of demand, which states that when the price of a good rises, quantity demand falls. The income effect, where a change in price affects consumers' purchasing power and their ability to purchase the good, is not evident in this scenario. The law of diminishing marginal utility and the fact that marginal willingness to pay falls may play a role in shaping the demand curve but are not directly related to the change in quantity demanded due to a price increase.

Question 11

What must be true in terms of the income effect, the substitution effect, and the type of good for the good's demand curve to be upward sloping?

Accepted Answer

The answer of What must be true in terms of...

Question 12

We can derive the market demand curve for gold earrings

Accepted Answer

The market demand curve for gold earrings can be derived by adding horizontally the individual demand curves of each gold earring consumer. This assumes that the tastes of all consumers are not necessarily similar, but rather that the demand curves represent the preferences and willingness to pay of each individual consumer in the market. By adding these individual demand curves, we can derive the overall demand for gold earrings in the market.

Question 13

The demand curve for a Giffen good slopes upward.

Accepted Answer

A Giffen good is a type of inferior good where the quantity demanded increases as the price increases. This means that the demand curve for a Giffen good slopes upward, which is opposite to the usual downward-sloping demand curve seen for normal goods.

Question 14

Economists Robert Jensen and Nolan Miller reasoned that to be a Giffen good, with an income effect larger than its substitution effect, a good must be ________ and make up a ________ portion of a consumer's budget.

Accepted Answer

Giffen goods are rare and inferior goods with limited substitutes. When the price of an inferior good increases, individuals' budget constraints become more stringent. They have less money to spend overall, and the price increase may also encourage them to buy more of the inferior good because they believe they cannot afford a superior substitute, making the substitution effect negative. Therefore, for a good to be a Giffen good, its income effect must be larger than its substitution effect. It implies that the proportion of the good's cost in the consumer's budget must be significant.

Question 15

A Giffen good could be either a normal good or an inferior good.

Accepted Answer

A Giffen good is specifically a type of inferior good, where demand increases as the price increases, due to the income effect outweighing the substitution effect.

Question 16

The income effect due to a price decrease will result in an increase in the quantity demanded for

Accepted Answer

The income effect due to a price decrease for a normal good will result in an increase in quantity demanded because the consumer's purchasing power has increased. As the price of the good has decreased, the consumer has additional income to purchase even more of the good. On the other hand, a Giffen good is an inferior good that has a positive income effect, meaning that as the price of the good decreases, the income effect leads to a decrease in quantity demanded. A decrease in price of an inferior good will increase the quantity demanded due to the income effect, but not as much as the substitution effect. A public good, on the other hand, has no price and is non-excludable. Therefore, the income effect can't be observed in a public good.

Question 17

The income effect of a price increase for a Giffen good outweighs the substitution effect.

Accepted Answer

In the case of a Giffen good, the income effect dominates the substitution effect when the price of the good increases. This is because the good is so essential to the consumer (usually due to low income and lack of substitutes) that they will continue to purchase it, even if the price increases. As a result, the increase in price leads to a decrease in the consumer's purchasing power, causing them to decrease their consumption of other goods, resulting in a larger income effect than substitution effect.

Question 18

For a demand curve to be upward sloping, the good would have to be an inferior good, and

Accepted Answer

If the good is inferior, then as income increases, consumers will tend to buy less of the good and switch to higher quality substitutes. This means that the income effect (which leads to a decrease in quantity demanded as income increases) will be greater than the substitution effect (which leads to an increase in quantity demanded as the price of the good decreases). This results in an upward sloping demand curve. Option A correctly describes this relationship.

Question 19

The income effect results in consumers increasing the quantity of normal goods demanded when the price falls.

Accepted Answer

The income effect refers to the change in consumer demand for a product that occurs as a result of a change in the consumer's purchasing power, due to a change in the product's price. When the price of a normal good decreases, the consumer's purchasing power increases, leading to an increase in the quantity demanded of that good. This is known as the income effect. Therefore, the statement "The income effect results in consumers increasing the quantity of normal goods demanded when the price falls" is true.
