Question 1

Which of the following best describes the Law of Demand in macroeconomics?

Accepted Answer

As the price of a good increases, the quantity demanded decreases, ceteris paribus.

Question 2

Suppose the government imposes a price ceiling below the equilibrium price for rental apartments. What is the most likely outcome in the market?

Accepted Answer

A shortage of rental apartments, as quantity demanded exceeds quantity supplied.

Question 3

Which equation correctly represents the relationship between quantity demanded ($$Q_d) $$and price ($$P) $$for a linear demand curve?

Accepted Answer

$$Q_d = a - bP$$

Question 4

If the supply curve for a product is given by $$Q_s = -10 + 2P$$ and the demand curve is $$Q_d = 50 - P$$, what is the equilibrium price?

Accepted Answer

$$P = 20$$

Question 5

Which of the following statements about the Law of Supply is correct?

Accepted Answer

There is a positive relationship between price and quantity supplied, ceteris paribus.

Question 6

Macroeconomics is best described as:

Accepted Answer

The study of the economy as a whole, including issues like unemployment, inflation, and economic growth.

Question 7

If the demand for a product increases while supply remains constant, what will happen to the equilibrium price and quantity?

Accepted Answer

Equilibrium price and quantity will both increase.

Question 8

Which of the following is an example of a 'ceteris paribus' assumption in economic analysis?

Accepted Answer

Assuming all other factors remain constant when analyzing the effect of price on demand.

Question 9

A scientific method in economics involves which of the following steps?

Accepted Answer

Observation, hypothesis formation, testing, and analysis.

Question 10

If the demand curve for a good is $$Q_d = 100 - 2P$$ and the supply curve is $$Q_s = 20 + 3P$$, what is the equilibrium quantity?

Accepted Answer

$$Q = 60$$

Question 11

Which of the following would cause a shift in the demand curve for coffee to the right?

Accepted Answer

An increase in consumer income, assuming coffee is a normal good.

Question 12

If the price of a substitute good increases, what is the likely effect on the demand for the original good?

Accepted Answer

Demand for the original good will increase.

Question 13

Which of the following best illustrates the concept of opportunity cost?

Accepted Answer

Choosing to attend university means giving up the income you could have earned by working.

Question 14

Suppose a new technology reduces the cost of producing smartphones. What is the likely effect on the supply curve?

Accepted Answer

The supply curve will shift to the right.

Question 15

Which of the following is NOT a characteristic of a social science like economics?

Accepted Answer

It relies solely on laboratory experiments for data.

Question 16

If the government introduces a subsidy for electric cars, what is the most likely effect on the market for electric cars?

Accepted Answer

The supply curve will shift to the right, leading to a lower equilibrium price and higher quantity.

Question 17

Which of the following best describes a 'positive statement' in economics?

Accepted Answer

"An increase in the minimum wage will lead to higher unemployment among teenagers."

Question 18

If the price elasticity of demand for a product is $$|E_d| \u003e 1$$, what does this imply about consumer responsiveness?

Accepted Answer

Demand is elastic; consumers are highly responsive to price changes.

Question 19

A decrease in the price of a good causes a movement along the demand curve. This is known as:

Accepted Answer

A change in quantity demanded.

Question 20

Suppose the demand and supply for a product are given by $$Q_d = 80 - 4P$$ and $$Q_s = 2P + 20. $$What is the equilibrium price?

Accepted Answer

$$P = 10$$
