Question 1

Which of the following best describes the Production Possibility Frontier (PPF)?

Accepted Answer

The PPF is a curve that shows all possible combinations of two goods that can be produced using all available resources efficiently.

Question 2

Suppose a country can produce either 1000 cars or 500 computers with all its resources. What is the opportunity cost of producing one car in terms of computers?

Accepted Answer

$0.5$ computers

Question 3

If the PPF is bowed outward, what does this indicate about opportunity costs?

Accepted Answer

Opportunity costs are increasing as more of one good is produced.

Question 4

Which of the following statements about marginal cost is correct?

Accepted Answer

Marginal cost is the opportunity cost of producing one more unit of a good.

Question 5

A point inside the PPF represents:

Accepted Answer

An inefficient allocation of resources.

Question 6

If the marginal benefit of consuming a good is greater than its marginal cost, what should a rational consumer do?

Accepted Answer

Increase consumption of the good.

Question 7

Which of the following equations correctly represents the slope between two points $(x_0, y_0)$ and $(x_1, y_1)$?

Accepted Answer

$\frac{y_1 - y_0}{x_1 - x_0}$

Question 8

Suppose Bob can produce 100 hamburgers or 50 milkshakes in a day, while Sam can produce 50 hamburgers or 100 milkshakes. Who has the comparative advantage in producing hamburgers?

Accepted Answer

Bob

Question 9

Which of the following best defines allocative efficiency?

Accepted Answer

Allocative efficiency occurs when it is impossible to produce more of one good without giving up some other good that provides greater benefit.

Question 10

If a country is operating on its PPF, which of the following is true?

Accepted Answer

The country is using all its resources efficiently.

Question 11

Mary can produce either 50 cakes or 100 cookies in a day. What is Mary's opportunity cost of producing one cake?

Accepted Answer

$2$ cookies

Question 12

Which of the following is NOT a reason for the outward curvature of the PPF?

Accepted Answer

Resources are equally suited to producing both goods.

Question 13

Suppose the marginal benefit of the 5th unit of a good is $10$, and the marginal cost is $8$. What should be done to achieve allocative efficiency?

Accepted Answer

Produce more than 5 units.

Question 14

Which of the following statements about absolute and comparative advantage is correct?

Accepted Answer

A person with a lower opportunity cost of producing a good has a comparative advantage in that good.

Question 15

If the marginal cost curve is upward sloping, what does this imply about the production process?

Accepted Answer

Producing additional units becomes increasingly costly.

Question 16

A country can produce either 200 tons of wheat or 100 tons of rice. If it is currently producing 100 tons of wheat and 50 tons of rice, what can you conclude?

Accepted Answer

The country is producing efficiently and is on its PPF.

Question 17

Which of the following best describes the concept of scarcity?

Accepted Answer

Scarcity means that resources are limited and cannot satisfy all human wants.

Question 18

If the equation of a line is $y = -x + 20$, what is the slope and what does it indicate?

Accepted Answer

The slope is $-1$, indicating a negative relationship between $x$ and $y$.

Question 19

Which of the following is true about gains from trade?

Accepted Answer

Gains from trade arise when individuals or countries specialize according to their comparative advantage.

Question 20

If the marginal benefit curve is downward sloping, what does this imply about consumer preferences?

Accepted Answer

Consumers value each additional unit less than the previous one.
