Theme 1 (1.1)(1.2) Flashcards
What are the main determinants of supply
Price (p), Cost of Production (Land, Labour and Capital), Weather (for agricultural products), Natural Disasters, Technology
What does a point on a supply curve show?
It shows the amount that will be supplied at each price level in a market
What would shift the supply curve for oil to the right?
If minimum wage in countries with oil reserves goes down then cost of wages and therefore production for the industry will go down and so there will be a higher supply and it will shift.
Define Price Elasticity of Supply
PES measures the responsiveness of supply to a change in price.
What is meant by equilibrium
Equilibrium is where supply =demand, it is a steady state where there is no tendency to change, unless there is an exogenous shock that pushes the market out of equilibrium.
what is the Market Clearing Price
The price at which the quantity supplied equals the quantity demanded: no excess. excess supply causes the price to drop until market clearing is reach, excess demand causes the price to rise until market clearing is reached. Adam smith called this the invisible hand of market forces.
In a competitive market, what effect would it have on supply if a new supplier entered the market
supply would increase and price would fall
what is meant by joint demand or complimentary goods
goods that are consumed together
give an example of two goods in joint demand
razors and shaving foam
what is the impact on complimentary goods if there is an increase in market supply of one of them
if there is an increase of price in one, it will be less demanded meaning the other good is less necessary and also then demanded less
what is meant by composite demand
when one good is demanded for 2 or more different purposes
give an example of 2 goods in composite demand
milk is used for drinking and making cheese/yoghurt/butter. Sunflower seeds used for bread and making oil/biofuel.
what is the impact on both products if there is a rise in demand for one of the goods that something is in composite demand for e.g. milk - butter or cheese
if their is an increase in demand for cheese, then there is less milk available for making butter so the supply of butter will fall
what is derived demand
when the demand for a good is driven by the demand for another good
give an example of a good whose demand is derived from another product
labour, where the demand for apps causes demand for computer programmers as they can make apps. Similarly, the demand for steel is derived from the demand for cars and construction
what is the impact on both goods (reference derived demand) if there is an increase in market demand of the good
if the demand for cars increases then there will be more demand for steel used to make cars
what is joint supply
when one good is a by-product of another good
give an example of two products in joint supply
beef and leather
what is the impact on both products (reference joint supply) if there is an increase in supply of one of the goods.
In order for the supply of either beef or leather, more cows must be killed which increases the supply of the other. So an increase in the supply of one of the goods increases the supply of both goods
What are the three functions of the price mechanism and explain what each means
- Rationing - When goods become more scarce, the price rises, this acts to dampen down demand for this good, so that only people who can afford it will continue to demand it, this is a from of rationing as now the product will not run out (Ceteris Paribus)
- Incentives - As the price of a product rises, the supply also rises as a higher price means more of a profit margin for producers so there is more incentive for them to produce as much as they can
- Signalling - A price rise sends a signal to a market to produce more of that good as it is becoming relatively scarce. This signal diverts factors of production from other goods to reduce scarcity in another area.
Define consumer surplus
consumer surplus is the difference between the price a consumer is willing to pay and the price they actually pay (the area above market price and below demand)
Define producer surplus
producer surplus is the difference between the price a producer is willing to accept and the price they actually do accept (the area below market price and above the supply curve)
Where on a supply and demand diagram is consumer surplus
below the demand curve (negative gradient curve) and above the market price. the area is a triangle with the hypotenuse facing upwards
where on a supply and demand diagram is producer surplus
above the supply curve (positive gradient curve) and below the market price. the area is a triangle with the hypotenuse facing downwards.
What happens to producer surplus if demand rises, reference a diagram
As you go from P1 to P2 (Market price has risen to expunge excess demand), the area illustrating producer surplus rises in size and therefore producer surplus rises as the supply curve stays the same but the market price has risen which enlarges the boundaries of the area
define indirect tax
an indirect tax is one where the liability can be passed on to a third party
give 2 examples of indirect taxes
VAT and Excise Duty tax are paid by the producer, but they can pass on some of the liability for the tax onto consumers in higher prices. VAT therefore indirectly affects consumers and is known as consumption tax
describe through use of a diagram the impact on supply of an increase in VAT
An increase in VAT will increase the cost of production for the firm which shifts the supply curve of the product to the left. because VAT is a % of the selling price, the amount of tax paid per product increases as the price of the product increases. This is why the shift makes the new supply curve steeper rather than just a parallel shift (the shift is skewed). The vertical difference between the old and the new supply curve at the new equilibrium gives you the unit cost of the tax. This amount multiplied by the units sold gives you the tax revenue to the government. At the new equilibrium, the tax revenue would be the area worked out by vertical height between the supply curves X the horizontal length up toward the new quantity. (see diagrams on slides for help)
what is the impact on supply of excise duty
excise duty is paid at the same rate regardless of what the selling price is. this is why the shift is parallel rather than skewed
where on a supply and demand diagram is producer and consumer incidence
The area above the old equilibrium price and below the new equilibrium price is the consumer tax burden.
The area between the old equilibrium price and the price that the producer gets to keep is the producer tax burden (see slides for help)
where is the area on a s+d diagram representing tax revenue to the government
the consumer and producer tax burden added together= total tax revenue. or new quantity supplied x unit cos of tax = total tax revenue
what happens to producer incidence if demand is elastic and VAT increases.
if the demand is elastic and VAT increases then the burden of tax falls mainly on the producer. this is because consumers in the market will not accept a price rise, so price will not rise significantly following an increase in tax. Nevertheless the tax must be paid so producers must pay it by cutting profit margins.
what happens to consumer incidence if demand is inelastic and VAT increases
if the demand is inelastic and VAT increases then the burden of tax falls mainly on the consumer. as the consumers in the market will accept a price rise, and increase in VAT means the producer can continue passing this burden on to the consumer therefore the consumer incidence will increase.
define subsidy
A subsidy is a payment from the government to a producer, subsidies are usually paid as an amount per item produced e.g. £1 per tonne produced of wheat
what is the impact on supply of a subsidy
there will be increased supply and the supply curve will shift to the right
where on s+d diagram is the cost to the government of a subsidy
the area worked out by the new quantity X the vertical height between the old and new supply curves at the new equilibrium.
how are consumers affected by a subsidy
price falls so consumers benefit from an increase in consumer surplus. the benefit to consumers can be calculated as the decrease in price multiplied by the new quantity supplied
how are producers affected by a subsidy
producers also benefit as the price they receive + the unit subsidy means that they effectively take home an even higher price per unit sold. The benefit is the difference between the price originally received and the new price multiplied by the number of units sold.
how is the government affected by a subsidy
there are significant costs to the government of a subsidy. Governments usually subsidise products and services that benefit society in some way and which help achieve their own goals. However subsidies have an opportunity cost and they are also frowned upon by the WTO (world trade organisation) as they give British producers an unfair advantage over international competitors. They are known as Non-Tariff Barriers so they must be used with caution.
