Question 1

Suppose that the market demand curve for cauliflower is a function of the price of cauliflower, the price of broccoli, and income. If the partial derivative of quantity demanded of cauliflower with respect to income is positive:

Accepted Answer

If the partial derivative of quantity demanded of cauliflower with respect to income is positive, it means that as income increases, the quantity demanded of cauliflower also increases. This is a characteristic of a normal good. Therefore, cauliflower is a normal good. We cannot make any conclusion about broccoli based solely on this information.

Question 2

Suppose that the market demand curve for sunflowers is a function of the price of sunflowers, the price of roses, and income. If the partial derivative of quantity demanded of sunflowers with respect to income is negative:

Accepted Answer

A negative partial derivative of quantity demanded with respect to income indicates that as income increases, the quantity demanded of sunflowers decreases. This is a characteristic of inferior goods, not normal goods. Therefore, sunflowers are inferior goods. The information given does not provide any indication about the nature of roses (whether they are normal or inferior goods).

Question 3

Suppose that the market demand curve for cauliflower is a function of the price of cauliflower, the price of broccoli, and income. If the partial derivative of quantity demanded of cauliflower with respect to the price of broccoli is positive, cauliflower and broccoli are:

Accepted Answer

A positive partial derivative of quantity demanded of cauliflower with respect to the price of broccoli suggests that as the price of broccoli increases, the quantity demanded of cauliflower also increases. This indicates that cauliflower and broccoli are substitutes, meaning that consumers view them as alternatives to each other, and so an increase in price of one will lead to an increase in demand for the other.

Question 14

To test whether the law of demand holds using calculus, you should:

Accepted Answer

To test the law of demand using calculus, we need to take the partial derivative of quantity demanded with respect to price (i.e. the derivative of Q^D with respect to P). The law of demand states that as the price of a good increases, the quantity demanded decreases, which means that the slope of the demand curve should be negative. Taking the partial derivative with respect to P will give us the slope of the demand curve at the market price. If this derivative is negative, then the law of demand holds. Therefore, B is the correct choice.

Question 15

Suppose that the market demand curve for sunflowers is a function of the price of sunflowers, the price of roses, and income. If the partial derivative of quantity demanded of sunflowers with respect to the price of roses is negative, sunflowers and roses are:

Accepted Answer

Question 19

To test whether the law of supply holds using calculus, you should:

Accepted Answer

The law of supply states that as the price of a good increases, the quantity supplied of that good will also increase. To test this using calculus, we can take the partial derivative of the quantity supplied function with respect to price. If this derivative is positive at the market price, then the law of supply holds. This is because a positive derivative means that an increase in price leads to an increase in quantity supplied, which is consistent with the law of supply. Therefore, choice A is the best option.
