Question 1

The income effect of a price change refers to the impact of a change in

Accepted Answer

The income effect of a price change refers to the impact of a price change on a consumer's purchasing power. When the price of a good increases, the consumer's purchasing power decreases, and they are no longer able to afford as much of the good as they once were. This leads to a decrease in the quantity demanded, which is known as the income effect.

Question 2

Table 3-1
 
-Refer to Table 3-1.The table above shows the demand schedules for loose-leaf tea of two individuals (Sunil and Mia)and the rest of the market.If the price of loose-leaf tea rises from $3 to $4, the market quantity demanded would

Accepted Answer

The market quantity demanded decreases by the sum of the decreases in quantity demanded by Sunil, Mia, and the rest of the market when the price rises from $3 to $4.

Question 3

If the price of grapefruit rises, the substitution effect due to the price change will cause

Accepted Answer

When the price of grapefruit rises, consumers are likely to substitute it with cheaper alternatives such as oranges or other fruits, thereby decreasing the quantity of grapefruit demanded. This is known as the substitution effect. However, there may also be an income effect where people may consume less of all fruits if their overall disposable income decreases due to the price hike. However, the income effect is less likely to be significant in this case because fruit is a small portion of most people's budget.

Question 4

The ________ effect refers to the change in quantity demanded for a good that results from the effect of a change in the good's price on consumers' purchasing power.

Accepted Answer

The income effect refers to the change in quantity demanded for a good that results from the effect of a change in the good's price on consumers' purchasing power. As the price of a good increases, the purchasing power of consumers' income decreases, and they may choose to buy less of the good. Conversely, as the price of a good decreases, the purchasing power of consumers' income increases, and they may choose to buy more of the good. The other options listed are not related to the change in quantity demanded resulting from a change in price.

Question 5

What is the difference between an "increase in demand" and an "increase in quantity demanded"?

Accepted Answer

An "increase in demand" refers to a shift of the entire demand curve, either to the right or left, representing a change in consumer willingness and ability to buy a product at all possible prices. On the other hand, an "increase in quantity demanded" refers to a movement along a given demand curve, only caused by a change in the product's price.

Question 6

When the price of a normal good falls, consumers buy a larger quantity because of the ________ effect and the ________ effect.

Accepted Answer

When the price of a normal good falls, consumers have an incentive to substitute the good for other goods they would have purchased at a higher price. This is known as the substitution effect. Additionally, consumers' purchasing power increases as the price of the good falls, allowing them to buy more of the good (and possibly other goods as well). This is known as the income effect.

Question 7

The demand by all the consumers of a given good or service is the ________ for the good or service.

Accepted Answer

Market demand is the total amount of a good or service that all consumers are willing and able to buy at a given price level. It is determined by the aggregate of individual consumer demands.

Question 8

By 2017, Pepsi and Coke were attempting to increase their profits in the bottled water market by introducing premium water brands.Pepsi and Coke introduced LIFEWTR and Smartwater, respectively, while competitors like Nestle and Danone produced their own versions of premium water.The premium water brands marketed to compete with LIFEWTR and Smartwater would be considered

Accepted Answer

Competitors producing their own versions of premium water indicate that these brands are substitutes for LIFEWTR and Smartwater, not complements. Premium water is generally considered a luxury item, so it is unlikely that competitors would produce inferior goods compared to LIFEWTR and Smartwater. Additionally, because premium water is a luxury item, it is considered a normal good, so neither LIFEWTR nor Smartwater would be considered superior to the other.

Question 9

A movement along the demand curve for toothpaste would be caused by

Accepted Answer

A movement along the demand curve for toothpaste would only be caused by a change in the price of toothpaste itself. A change in the price of related goods (toothbrushes) or factors affecting consumer income or population would cause a shift in the demand curve rather than a movement along it.

Question 10

Holding everything else constant, an increase in the price of MP3 players will result in

Accepted Answer

An increase in the price of MP3 players will result in a decrease in the quantity of MP3 players demanded, as consumers will be less willing and able to purchase MP3 players at a higher price. This is a movement along the demand curve, not a shift in the demand curve itself. The supply of MP3 players will remain unchanged in this scenario.

Question 11

If the amount of carbonated sodas consumed continues to decline as consumers continue to choose to buy healthier products, this will likely

Accepted Answer

Carbonated sodas and premium water are considered substitutes, as consumers may choose to switch from one to the other based on their preference for healthier options. Therefore, as the demand for carbonated sodas declines, the demand for premium water is likely to increase.

Question 12

The law of demand implies, holding everything else constant, that as the price of bagels increases.

Accepted Answer

According to the law of demand, as the price of a good increases, the quantity demanded of that good will decrease, ceteris paribus. This means that holding everything else constant (such as consumer income or preferences), consumers will be less willing and able to purchase bagels at a higher price. Thus, there will be a decrease in the quantity of bagels demanded.

Question 13

A change in all of the following variables will change the market demand for a product except

Accepted Answer

The market demand for a product is determined by various factors like population, income, tastes, and preferences. However, the price of the product is not considered a variable that changes the market demand since it is already reflected in the quantity demanded at different price levels. Therefore, the correct choice is A, the price of the product.

Question 14

By drawing a demand curve with ________ on the vertical axis and ________ on the horizontal axis, economists assume that the most important determinant of the demand for a good is the ________ of the good.

Accepted Answer

The demand curve is typically drawn with price on the vertical axis and quantity on the horizontal axis. This indicates that the most important determinant of demand is the price of the good. As the price of the good increases, the quantity demanded decreases and vice versa. Therefore, choice C is the best answer.

Question 15

If a demand curve shifts to the right, then

Accepted Answer

When a demand curve shifts to the right, it means that at every price level, consumers are demanding more of that good or service. This results in an increase in demand. Therefore, the correct choice is A.

Question 16

Which of the following will shift the demand curve for a good?

Accepted Answer

A decrease in the price of a complementary good makes the good more attractive to consumers, increasing demand and shifting the demand curve to the right.

Question 17

If the price of orchids falls, the substitution effect due to the price change will cause

Accepted Answer

If the price of orchids falls, the substitution effect due to the price change will lead consumers to substitute them for other more expensive goods, like roses. This would cause an increase in quantity demanded of orchids. However, it would not necessarily result in an increase in demand for orchids since the substitution effect would encourage consumers to purchase other substitute goods. The quantity supplied of orchids would not change as a result of the price change.

Question 18

If a demand curve shifts to the left, then

Accepted Answer

A leftward shift in the demand curve indicates a decrease in demand. This means at any given price level, consumers are willing to buy fewer units of the good or service.

Question 19

If, in response to an increase in the price of chocolate, the quantity of chocolate demanded decreases, then economists would describe this as

Accepted Answer

When the price of chocolate increases and the quantity demanded decreases, it is a movement along the demand curve, rather than a shift in the entire demand curve. This is known as a decrease in quantity demanded.
