Q: Suppose the marginal benefit curve for a good is given by $$MB = 55 - \frac{2.5}{6}Q. If $$the market price is $$40$$, what is the consumer surplus when $$Q = 36$$?

$$CS = \frac{1}{2} \times (55 - 40) \times 36 = 270$$

Question 1

Which resource allocation method is most likely to be used when a scarce resource cannot be effectively distinguished among potential users, such as in the allocation of university dorm rooms?

Accepted Answer

Allocation by lottery

Question 2

Suppose the marginal benefit curve for a good is given by $$MB = 55 - \frac{2.5}{6}Q. If $$the market price is $$40$$, what is the consumer surplus when $$Q = 36$$?

Accepted Answer

$$CS = \frac{1}{2} 	imes (55 - 40) 	imes 36 = 270$$

Question 3

Which of the following best describes producer surplus?

Accepted Answer

The difference between the price producers receive and the opportunity cost of producing the good, summed over the quantity sold.

Question 4

In a market for lawn services, six producers have minimum acceptable prices of $$12, 10$$, $$8, 6$$, $$4, and 2. If $$the market price is $10, what is the total producer surplus?

Accepted Answer

$$(10-12) + (10-10) + (10-8) + (10-6) + (10-4) + (10-2) = -2 + 0 + 2 + 4 + 6 + 8 = 18$$

Question 17

If the marginal cost of producing a good is $$MC = 2 + \frac{Q^2$}{6}$$ and the market price is $$10$$, what is the producer surplus for $$Q = 6$$ units?

Accepted Answer

$$PS = (10 - (2 + \frac{36}{6})) 	imes 6 = (10 - 8) 	imes 6 = 12$$
