The determination of equilibrium market prices Flashcards
What is the equilibrium price and quantity
This is when demand and supply meet
At equilibrium, what is the price called and what does this price indicate
At equilibrium the price is called The market clearing price.
- this indicates the price at which sellers are selling their stock at an acceptable rate
What is disequilibrium and when does this occur
Disequilibrium is when demand is not equal to supply.
- Disequilibrium occurs whenever there is excess demand or excess supply in a market
Define excess demand and when does excess demand occur
Excess demand is when the demand is greater than the supply
- occur when prices are too low or when demand is so high that supply cannot keep up with it
Why does excess demand lead to changes in price
Producers are selling quickly at a low price and not all buyers that are willing and able to buy are able to purchase the product.
- producers realise they can increase prices and generate more revenue and profits and so raise the price
- This causes a contraction in QD as some buyers no longer desire the good/service at a higher price
- This causes an extension in QS as other sellers are more incentivised to supply at higher prices
- price will increase until the market will have cleared the excess demand and we are at equilibrium price and quantity
State another word for excess demand
Shortage
Define excess supply and state when excess supply occurs
Excess supply is when the supply is greater than the demand
- occur when prices are too high or when demand falls unexpectedly
State another word for excess supply
Surplus
Why does excess supply lead to changes in price
- Producers realise they are not selling and that the price are too high.
- Some buyers want to purchase the G/S but are not willing to pay the high price.
- to eliminate excess supply, producers will lower prices, which will
encourage consumers to buy their goods, generating revenue - This causes a contraction in QS as some sellers no longer desire to supply at lower price
- This causes an extension in QD as buyers are more willing to purchase at lower prices
- When Qs is equal to Qd we are at equilibrium, the market will have cleared the excess supply
On the demand and supply curve, what happens to the quantity supplied and quantity demanded as price increases
As price goes up, we see a contraction in demand (QD decreases because goods are more expensive) and an extension in supply (Qs increases because higher prices mean more profit for producers)
On the demand and supply curve, what happens to the quantity supplied and quantity demanded as price decreases
when the price goes down, we see a contraction in supply (Qs decreases because a there is less incentive to supply at lower prices) and an extension in demand (Qd increases along our demand curve because goods are cheaper)
