Microeconomics Market Equilibrium
37 flashcards covering Microeconomics Market Equilibrium for the MICROECONOMICS Microeconomics Topics section.
Market equilibrium is a fundamental concept in microeconomics that refers to the point where the supply of goods matches demand. This concept is defined by the principles outlined in the curriculum of the Principles of Microeconomics course, which emphasizes the interaction between buyers and sellers in a market. Understanding market equilibrium helps to analyze how changes in market conditions affect prices and quantities.
In practice exams and competency assessments, questions about market equilibrium often present scenarios requiring the identification of shifts in supply and demand curves, as well as their effects on price and quantity. Common traps include misinterpreting the direction of shifts or failing to account for external factors that can influence market dynamics. A frequent oversight is neglecting to consider how government interventions, like price ceilings or floors, can disrupt equilibrium.
To enhance your understanding, remember that real-world markets can be influenced by factors beyond simple supply and demand, such as consumer preferences and global events.

- 01
What is market equilibrium?
Market equilibrium is the point where the quantity demanded by consumers equals the quantity supplied by producers, resulting in a stable market price (Mankiw, Principles of Economics).
- 02
What happens when the market price is above equilibrium?
When the market price is above equilibrium, a surplus occurs as quantity supplied exceeds quantity demanded, leading to downward pressure on prices (Krugman, Principles of Economics).
- 03
What occurs when the market price is below equilibrium?
When the market price is below equilibrium, a shortage arises as quantity demanded exceeds quantity supplied, resulting in upward pressure on prices (Wells, Principles of Economics).
- 04
How is equilibrium price determined?
Equilibrium price is determined by the intersection of the supply and demand curves in a market, where the two curves meet (Mankiw, Principles of Economics).
- 05
What effect does an increase in demand have on market equilibrium?
An increase in demand shifts the demand curve to the right, leading to a higher equilibrium price and quantity (Krugman, Principles of Economics).
- 06
What effect does a decrease in supply have on market equilibrium?
A decrease in supply shifts the supply curve to the left, resulting in a higher equilibrium price and a lower equilibrium quantity (Wells, Principles of Economics).
- 07
Define excess supply.
Excess supply occurs when the quantity supplied exceeds the quantity demanded at a given price, leading to a surplus in the market (Mankiw, Principles of Economics).
- 08
Define excess demand.
Excess demand occurs when the quantity demanded exceeds the quantity supplied at a given price, resulting in a shortage in the market (Krugman, Principles of Economics).
- 09
What is the role of price in achieving market equilibrium?
Price acts as a signal and incentive in the market, guiding producers and consumers to adjust their behaviors until equilibrium is reached (Wells, Principles of Economics).
- 10
How does a price ceiling affect market equilibrium?
A price ceiling, set below equilibrium, can lead to a persistent shortage as it prevents prices from rising to the equilibrium level (Mankiw, Principles of Economics).
- 11
How does a price floor impact market equilibrium?
A price floor, set above equilibrium, can result in a surplus as it prevents prices from falling to the equilibrium level (Krugman, Principles of Economics).
- 12
What is the impact of a tax on market equilibrium?
A tax on a good typically shifts the supply curve to the left, increasing the equilibrium price and decreasing the equilibrium quantity (Wells, Principles of Economics).
- 13
What is a shift in demand?
A shift in demand refers to a change in consumer preferences, income, or prices of related goods, resulting in a new demand curve (Mankiw, Principles of Economics).
- 14
What is a shift in supply?
A shift in supply occurs when factors such as production costs, technology, or the number of suppliers change, leading to a new supply curve (Krugman, Principles of Economics).
- 15
Define consumer surplus.
Consumer surplus is the difference between what consumers are willing to pay for a good and what they actually pay, representing the benefit to consumers (Wells, Principles of Economics).
- 16
Define producer surplus.
Producer surplus is the difference between the market price a producer receives for a good and the minimum price they would be willing to accept, representing the benefit to producers (Mankiw, Principles of Economics).
- 17
What is the significance of the equilibrium quantity?
The equilibrium quantity is significant as it represents the amount of goods that are bought and sold at the equilibrium price, ensuring market efficiency (Krugman, Principles of Economics).
- 18
What is the impact of technology on supply?
Technological advancements typically increase supply by lowering production costs, shifting the supply curve to the right (Wells, Principles of Economics).
- 19
How does a change in consumer income affect demand?
An increase in consumer income generally leads to an increase in demand for normal goods, shifting the demand curve to the right (Mankiw, Principles of Economics).
- 20
What is the effect of substitutes on demand?
An increase in the price of a substitute good typically leads to an increase in demand for the original good, shifting its demand curve to the right (Krugman, Principles of Economics).
- 21
How do complements affect market equilibrium?
A decrease in the price of a complementary good usually increases the demand for the original good, potentially raising both equilibrium price and quantity (Wells, Principles of Economics).
- 22
What is the long-run adjustment in a competitive market?
In the long run, firms in a competitive market will enter or exit based on profits, leading to a new equilibrium where economic profits are zero (Mankiw, Principles of Economics).
- 23
What is the impact of government intervention on market equilibrium?
Government intervention, such as price controls or subsidies, can disrupt market equilibrium by creating surpluses or shortages (Krugman, Principles of Economics).
- 24
How do expectations of future prices affect current demand?
If consumers expect prices to rise in the future, current demand may increase as they buy more now, shifting the demand curve to the right (Wells, Principles of Economics).
- 25
What is the relationship between elasticity and market equilibrium?
The elasticity of demand and supply affects how much equilibrium price and quantity change in response to shifts in demand or supply (Mankiw, Principles of Economics).
- 26
Define equilibrium quantity in a competitive market.
Equilibrium quantity in a competitive market is the quantity of goods sold at the equilibrium price where supply equals demand (Krugman, Principles of Economics).
- 27
What is a market shortage?
A market shortage occurs when the quantity demanded exceeds the quantity supplied at a given price, often leading to increased prices (Wells, Principles of Economics).
- 28
How can government subsidies affect market equilibrium?
Government subsidies can lower production costs, increase supply, and shift the supply curve to the right, lowering equilibrium prices and increasing quantities (Mankiw, Principles of Economics).
- 29
What is the relationship between demand and price?
The law of demand states that, all else being equal, as the price of a good decreases, the quantity demanded increases (Krugman, Principles of Economics).
- 30
What is the relationship between supply and price?
The law of supply states that, all else being equal, as the price of a good increases, the quantity supplied increases (Wells, Principles of Economics).
- 31
How do market expectations influence supply?
If producers expect higher future prices, they may reduce current supply to sell more later, shifting the supply curve to the left (Mankiw, Principles of Economics).
- 32
What is the effect of a decrease in consumer preferences for a good?
A decrease in consumer preferences for a good shifts the demand curve to the left, resulting in a lower equilibrium price and quantity (Krugman, Principles of Economics).
- 33
How does competition affect market equilibrium?
In a competitive market, firms strive to maximize profits, leading to adjustments in supply and demand until equilibrium is reached (Wells, Principles of Economics).
- 34
What is the impact of a natural disaster on supply?
A natural disaster can disrupt production and supply chains, shifting the supply curve to the left and increasing equilibrium prices (Mankiw, Principles of Economics).
- 35
How do changes in the number of suppliers affect market equilibrium?
An increase in the number of suppliers typically increases market supply, shifting the supply curve to the right and lowering equilibrium prices (Krugman, Principles of Economics).
- 36
What is the effect of price elasticity of demand on total revenue?
If demand is elastic, a decrease in price increases total revenue; if inelastic, a decrease in price decreases total revenue (Wells, Principles of Economics).
- 37
How does the concept of opportunity cost relate to market equilibrium?
Opportunity cost influences consumer and producer decisions, affecting demand and supply, and ultimately shaping market equilibrium (Mankiw, Principles of Economics).
