Demand and supply
What happens to the demand if the price decreases
-if price goes down demand will increase
-demand on x axis, price on Y axis.
-moves up and down the line not parallel
What happens to demand if income decreases:
-if income decreases demand decreases as people have less money to spend
-price on y axis, quantity on x axis
-the line moves parallel to create a new line.
-there will be more demand for cheaper items and less demand for higher prices
What is a complement and substitute:
-complement: something that you buy with the original peice
-substitute: something that is replaced by the original as the same but different brand
Determinants of supply: What is price and cost
-price: the amount that a customer is willing and able to pay
-cost: the amount spent by a business making/supplying/buying in the products
What happens when price goes up to the supply
-supply increase with increase of price as the business are able to supply more products
-supply graph:
Price on y axis, quantity on x axis. The supply moves up and down 1 line.
What happens when costs goes up. What does this do to the supply
-if costs go up supply goes down as the business can’t supply more with higher costs
Supply graph:
Price on y axis, quantity on y axis. 2 lines with change in costs. The line moves towards the x axis
What is tax and subsidies: and what happens to them if they both increase
-tax: is a mandatory contribution to government pay that is forced
Graph: if tax increase then supply will go down/ towards x axis.
-subsidies: money given out to businesses by the government
Graph: if they increase then supply will increase as they can afford to make more. Line moves away from the x axis
What happens to supply of original product with the decrease of price. And what happens to subsidy products Eg/ Coca Cola
And other way round
-increase in demand of Coke causes a increase in supply of coke. Pepsi supply decreases as demand decreases
-if demand of coke decrease supply will decrease and supply of Pepsi increases as demand increases
What is an energy price cap and why is it effecting suppliers
-a bid to limit the price a supplier can charge per unit of electricity and gas.
-it is effecting suppliers as they can’t increase the price of gas due to teh cap
How does a supply and demand graph look like with an increase in price
-price on y axis
-quantity on x axis
-supply going up
-demand going down with 2 lines.
-Price 1 has a lower Q1 with a lower equilibrium (where the lines cross) and a higher supply
-price 2 has a higher Q2 with a higher equilibrium and higher supply
What happens when there is a decrease in supply.
-price on y axis
-quantity on x axis
-P1 has a lower Equilibrium with a higher demand and quantity
-P2 has a higher equilibrium with a lower quantity sold and lower supply
What does excess and shortage mean and what do each look like in a graph
-excess: more supply then demand, and so if they decrease the price they will have an increase in demand.
Graph: gap at the top of the x from where price line hits demand line to supply.
-shortage: more demand then supply. To reduce demand increase the price.
Graph: the gap in the bottom of the x where the line from price hits supply line to where price hits the demand line.
What is elasticity and inelasticity of demand
Elasticity: measures how sensitive quality demanded is to a change in price. When there is an increase in price demand decreases (luxury goods)
Inelasticity: when there is no change in demand when price increase as they are often necessary items that need to be brought even with the change of price.
What is market size and growth and share:
-size: expressed as the collective value of the goods/services that buyers purchase
