#1
Which of the following is a characteristic of a perfectly competitive market?
Many buyers and many sellers
ExplanationPerfect competition involves numerous buyers and sellers, ensuring no individual has significant market control.
#2
In economics, what does the term 'equilibrium' refer to?
A condition where quantity supplied equals quantity demanded
ExplanationEquilibrium in economics denotes the balance point where the quantity supplied equals the quantity demanded.
#3
Which of the following is a characteristic of a market in disequilibrium?
Excess supply
ExplanationDisequilibrium occurs when quantity supplied does not match quantity demanded, resulting in surplus or shortage.
#4
What happens to the equilibrium price and quantity when demand increases and supply decreases?
Price increases, quantity decreases
ExplanationWhen demand rises while supply falls, equilibrium price tends to rise while quantity traded decreases.
#5
What happens to market equilibrium if both demand and supply increase by the same amount?
Equilibrium price and quantity remain unchanged
ExplanationSimultaneous increases in demand and supply, if balanced, lead to no change in equilibrium price or quantity.
#6
Which of the following would most likely result in an increase in the equilibrium price and quantity of coffee?
A decrease in the cost of producing coffee
ExplanationReduced production costs typically lead to increased supply, causing equilibrium price and quantity to rise.
#7
In a monopolistic market, what is true about the level of product differentiation?
Products are similar but not identical
ExplanationMonopolistic markets feature products that are differentiated but not distinct, allowing firms some pricing power.
#8
Which of the following scenarios would lead to a decrease in the equilibrium price of laptops?
An increase in the number of laptop manufacturers
ExplanationA rise in the number of manufacturers often increases supply, resulting in a decrease in equilibrium price.
#9
In a perfectly competitive market, what is true about the long-run equilibrium of firms?
Firms produce at the minimum of average total cost
ExplanationIn the long run, firms in perfect competition produce at the point where average total cost is minimized.
#10
What is the primary reason for a decrease in equilibrium quantity in a market?
Decrease in supply and increase in demand
ExplanationWhen supply falls while demand rises, equilibrium quantity generally decreases due to scarcity.
#11
What is the main factor that determines the elasticity of supply in a market?
The time period under consideration
ExplanationElasticity of supply varies depending on the time frame considered due to factors like production capacity adjustments.
#12
What is the effect of a technological advancement that reduces production costs on market equilibrium?
Decrease in equilibrium price and increase in equilibrium quantity
ExplanationTechnological advances lowering production costs usually lead to increased supply and lower prices in equilibrium.
#13
What is the effect of a decrease in the price of a complementary good on the equilibrium price and quantity of a product?
Equilibrium price increases, equilibrium quantity increases
ExplanationLower prices of complementary goods tend to increase demand, leading to higher equilibrium price and quantity.
#14
In a market with elastic demand and inelastic supply, what happens if there is an increase in production costs?
Equilibrium price increases, equilibrium quantity decreases
ExplanationIn such a market, with demand more responsive to price changes than supply, higher production costs lead to price hikes and quantity drops.
#15
What is the effect of a decrease in the price of raw materials used in production on market equilibrium?
Equilibrium price increases, equilibrium quantity increases
ExplanationLower raw material costs often lead to decreased production costs, increasing supply and lowering prices in equilibrium.
