Questions this Price determination deck will help you answer

Definition Flip

Define 'equilibrium' in the context of market price determination.

Answer Flip

Equilibrium is the state where market supply and demand balance each other, and as a result prices become stable. At this point, there is no pressure for prices to rise or fall.

Key Concept Flip

Explain the difference between 'equilibrium price' and 'equilibrium quantity'.

Answer Flip

Equilibrium price is the price at which the quantity demanded equals the quantity supplied. Equilibrium quantity is the amount of a good or service bought and sold at the equilibrium price.

Definition Flip

What does 'market clearing' mean in economics, and how does it relate to equilibrium?

Answer Flip

Market clearing occurs when the market reaches equilibrium, meaning all goods supplied are purchased by consumers. There is no surplus or shortage, leading to an efficient allocation of resources.

Definition Flip

Describe the condition that leads to a 'surplus' in the market.

Answer Flip

A surplus occurs when the quantity supplied is greater than the quantity demanded. This usually happens when the price is above the equilibrium price, leading to excess inventory.

Definition Flip

How does a 'shortage' arise in a market, and what is its effect on price?

Answer Flip

A shortage arises when the quantity demanded exceeds the quantity supplied. This happens when the price is below the equilibrium price, putting upward pressure on prices as consumers compete for limited goods.

Definition Flip

Explain 'excess supply' and its impact on market price.

Answer Flip

Excess supply, also known as a surplus, is when the quantity supplied exceeds the quantity demanded, often due to a price being set too high. This forces producers to lower prices to sell their goods, moving the market towards equilibrium.

Definition Flip

What is 'excess demand,' and how does it affect the market?

Answer Flip

Excess demand, also known as a shortage, is when the quantity demanded exceeds the quantity supplied, typically because the price is too low. This situation puts upward pressure on prices as consumers compete for the limited available goods.

Key Concept Flip

Illustrate, with an example, how a shift in the demand curve affects the equilibrium price and quantity.

Answer Flip

If demand for coffee increases (curve shifts right), the equilibrium price and quantity of coffee will both increase. Consumers are willing to pay more and buy more coffee at each price point.

Key Concept Flip

Illustrate, with an example, how a shift in the supply curve affects the equilibrium price and quantity.

Answer Flip

If supply of gasoline increases (curve shifts right), the equilibrium price will decrease, and the equilibrium quantity will increase. This will lead to more gasoline being sold at a lower price
