Question 5

If there is an increase in both the supply and demand for a good, which of the following will definitely occur?

Accepted Answer

Accepted Answer

Adam Smith argued that a nation's wealth is primarily derived from the productivity of its labor force and the ability to produce goods and services, which is facilitated by free markets and trade.

Question 7

Assume that supply decreases greatly and demand decreases slightly. Which of the following will happen?

Accepted Answer

When supply decreases greatly and demand decreases slightly, the equilibrium price will rise due to the reduced supply, and the equilibrium quantity will fall due to the combined effect of decreased supply and demand.

Question 8

Which of the following most accurately describes the invisible hand concept?

Accepted Answer

When both supply and demand decrease, the equilibrium quantity will definitely decrease, as there is less of the good being supplied and less being demanded. The effect on price is indeterminate without knowing the relative magnitudes of the shifts in supply and demand.

Question 15

Assume that supply decreases slightly and demand decreases greatly. Which of the following will happen?

Accepted Answer

When demand decreases greatly and supply decreases slightly, the equilibrium quantity will fall due to the larger decrease in demand. The equilibrium price will fall because the decrease in demand has a greater impact than the decrease in supply.

Question 16

Suppose both the equilibrium price and quantity rise for a particular product. Which of the following best explains this situation?

Accepted Answer

When both the equilibrium price and quantity increase, it indicates that demand has increased more than supply. This results in a higher price and quantity in the market.
