Question 1

Which of the following best describes optimization in economics?

Accepted Answer

Selecting the best feasible option by comparing total benefits and total costs.

Question 2

Suppose you are deciding between two apartments. Apartment A is closer to work and costs $$1,200/month, while Apartment B is farther and costs 1$$,000/month. If the opportunity cost of your time is $10/hour and Apartment B requires 20 more hours of commuting per month, what is the total monthly cost of Apartment B?

Accepted Answer

$1,200

Question 3

Optimization using marginal analysis involves:

Accepted Answer

Comparing the change in net benefit when moving from one option to another.

Question 4

If the marginal benefit (MB) of moving from Apartment West to Apartment East is $$25, and the marginal cost (MC) is 40$$, what is the marginal net benefit (MNB) of this move?

Accepted Answer

$-15

Question 5

Which of the following statements is TRUE regarding optimization using total value and marginal analysis?

Accepted Answer

Both methods give identical answers when applied correctly.

Question 6

A student is choosing between two study locations. Location X is closer but noisier, and Location Y is farther but quieter. The student values quiet at $$30/month and the extra travel time at 20/$$month. What is the net benefit of choosing Location Y over Location X?

Accepted Answer

$10

Question 7

Suppose the opportunity cost of your time increases from $$10/hour to 15/$$hour. How does this affect the optimal apartment choice if all other factors remain constant?

Accepted Answer

You are more likely to choose an apartment closer to work.

Question 8

Which formula correctly represents the marginal net benefit (MNB) in marginal analysis?

Accepted Answer

$$MNB = MB - MC$$

Question 9

If the total cost of Apartment A is $$1,180 and Apartment B is 1$$,200, which apartment should you choose according to optimization using total value?

Accepted Answer

Apartment A, because it has the lower total cost.

Question 10

A commuter is considering two job offers. Job 1 pays $$3,000/month and is 10 hours of commuting per month. Job 2 pays 2$$,800/month and is 2 hours of commuting per month. If the opportunity cost of time is $25/hour, which job offers the higher net benefit?

Accepted Answer

Job 2, with a net benefit of $2,750.

Question 11

Which of the following is NOT a reason why it may be difficult to make the best choice in optimization?

Accepted Answer

Always having perfect information.

Question 12

If the rent for an apartment is $$950/month and you value a special feature (like a view) at 25/$$month, what is the total value you assign to the apartment?

Accepted Answer

$975

Question 13

Suppose you are indifferent between two apartments, but then your job changes and you now travel to the airport less frequently. How should this affect your apartment choice?

Accepted Answer

You should re-calculate the marginal net benefit and may prefer the apartment farther from the airport.

Question 14

Which of the following best describes the principle of optimization at the margin?

Accepted Answer

The optimal alternative is the one where moving away makes you worse off and moving toward it makes you better off.

Question 15

If the marginal cost of moving from Apartment A to Apartment B is $$50 and the marginal benefit is 40$$, what should you do according to marginal analysis?

Accepted Answer

Stay at Apartment A.

Question 16

Which of the following is a real-world example of opportunity cost?

Accepted Answer

The value of time you give up commuting instead of working.

Question 17

Suppose the total cost of living in Apartment X is $$1,250/month and in Apartment Y is 1$$,200/month. If the marginal cost of moving from X to Y is $-50, what does this mean?

Accepted Answer

Moving to Y decreases your total cost by $50.

Question 18

If the opportunity cost of your time increases, what happens to the total cost of apartments with longer commutes?

Accepted Answer

The total cost increases.

Question 19

Which of the following equations correctly calculates total net benefit?

Accepted Answer

$$	ext{Total Net Benefit} = 	ext{Total Benefit} - 	ext{Total Cost}$$

Question 20

A city’s rent per square foot decreases as distance from the city center increases. This is an example of:

Accepted Answer

A negative relationship between rent and distance.
