Question 5

A model in economics is best described as:

Accepted Answer

Question 6

The ceteris paribus assumption is important in economic analysis because it:

Accepted Answer

Allows economists to isolate the effect of one variable by holding other factors constant.

Question 7

Which of the following best illustrates the concept of a direct relationship between two variables?

Accepted Answer

As the number of hours studied increases, exam scores increase.

Question 8

Suppose the slope of a line on a graph is calculated as follows: $$ 	ext{slope} = \frac{\Delta y}{\Delta x} = \frac{10}{2} . $$What is the value of the slope, and what does it indicate?

Accepted Answer

The slope is $$5$$, indicating a positive relationship.

Question 9

Which of the following is an example of a negative incentive?

Accepted Answer

A penalty for late payment of a credit card bill.

Question 10

A country that uses both government planning and market signals to allocate resources is said to have:

Accepted Answer

Which of the following statements is normative?

Accepted Answer

Artificial intelligence (AI) technologies are increasingly used in economics because they:

Accepted Answer

Help analyze large volumes of data to reveal hidden relationships for both microeconomic and macroeconomic decision making.

Question 16

A graph shows the relationship between the price of a product (on the x-axis) and the quantity purchased (on the y-axis). If the slope of the line is negative, this indicates:

Accepted Answer

An inverse relationship between price and quantity purchased.

Question 17

Bounded rationality suggests that:

Accepted Answer

People use rules of thumb because they cannot consider every possible alternative.

Question 18

Suppose a new government program offers low-interest loans to landlords who agree not to raise rents for ten years. What is the likely economic effect of this policy?

Accepted Answer

It will create housing supply at fixed rents by providing an incentive for landlords to participate.

Question 19

Which of the following best explains why economic models are useful even though they are simplifications of reality?

Accepted Answer

They help focus on essential relationships and make predictions about economic behavior.

Question 20
