Price determination Quiz

B. To determine the price and quantity of goods and services The price mechanism is the process by which the prices of goods and services are determined in a market, and it also helps to determine the quantity of goods and services that are bought and sold. The best distractor is A because it is a common misconception that the price mechanism controls supply, but it actually responds to changes in supply and demand.

C. A market where the quantity demanded equals the quantity supplied Market equilibrium occurs when the quantity demanded of a good or service equals the quantity supplied, and the market price is determined by the intersection of the demand and supply curves. The best distractor is D because it describes a market where the government intervenes, which is not a free market equilibrium.

B. There is a surplus of the good or service When the market price is above the equilibrium price, the quantity supplied is greater than the quantity demanded, resulting in a surplus. The best distractor is A because it describes what happens when the market price is below the equilibrium price, not above.

B. The equilibrium price increases, and the equilibrium quantity decreases A decrease in supply shifts the supply curve to the left, which increases the equilibrium price and decreases the equilibrium quantity. The best distractor is D because it describes what happens when both supply and demand increase.

D. The equilibrium price and quantity both increase An increase in demand shifts the demand curve to the right, which increases both the equilibrium price and quantity. The best distractor is B because it describes what happens when demand decreases.

A. The maximum price that can be charged for a good or service A price ceiling is a government-imposed maximum price that can be charged for a good or service. The best distractor is B because it describes a price floor, not a price ceiling.

B. A shortage of the good or service A price ceiling set below the equilibrium price creates a shortage because the quantity demanded exceeds the quantity supplied at the lower price. The best distractor is C because while a black market can result from a price ceiling, the immediate effect is a shortage.

B. The minimum price that can be charged for a good or service A price floor is a government-imposed minimum price that can be charged for a good or service. The best distractor is A because it describes a price ceiling, not a price floor.

A. A surplus of the good or service A price floor set above the equilibrium price creates a surplus because the quantity supplied exceeds the quantity demanded at the higher price. The best distractor is B because it describes what happens with a price ceiling, not a price floor.

A. A price ceiling is a maximum price, and a price floor is a minimum price A price ceiling is a government-imposed maximum price, while a price floor is a government-imposed minimum price. The best distractor is B because it incorrectly switches the definitions.

C. The equilibrium price and quantity both decrease A decrease in demand shifts the demand curve to the left, which decreases both the equilibrium price and quantity. The best distractor is B because it describes what happens when supply decreases.

A. The equilibrium price decreases, and the equilibrium quantity increases An increase in supply shifts the supply curve to the right, which decreases the equilibrium price and increases the equilibrium quantity. The best distractor is D because it describes what happens when both supply and demand increase.

B. The equilibrium price increases, and the equilibrium quantity decreases A government-imposed tax on a good or service increases the cost of production, which decreases supply and increases the equilibrium price while decreasing the equilibrium quantity. The best distractor is C because it describes what happens when both supply and demand decrease.

A. The equilibrium price decreases, and the equilibrium quantity increases A government-imposed subsidy on a good or service decreases the cost of production, which increases supply and decreases the equilibrium price while increasing the equilibrium quantity. The best distractor is D because it describes what happens when both supply and demand increase.

C. The equilibrium price and quantity both decrease A decrease in the price of a substitute good decreases demand for the original good, which shifts the demand curve to the left and decreases both the equilibrium price and quantity. The best distractor is A because it describes what happens when demand increases.

C. The equilibrium price and quantity both decrease An increase in the price of a complement good decreases demand for the original good, which shifts the demand curve to the left and decreases both the equilibrium price and quantity. The best distractor is B because it describes what happens when supply decreases.
