236
What is an example of a market where buffer stock schemes may be used
Wheat
237
In the case of a buffer stock scheme, what will happen if the supply of wheat is too low
The government will import more wheat to increase supply on the market, in order to reduce the price at which consumers have to pay for the commodity
238
Draw a graph showing a lack of supply of wheat and how the buffer stock is used as government intervention
Supply curve shift outwards, moving price below maximum price so that equilibrium for commodity is deemed affordable
239
In the case of a buffer stock scheme, what will happen if the supply of wheat is too high
The government will take wheat off of the market, in order to reduce its supply and so increase its price so that farmers receive minimum price (acceptable revenue)
240
Draw a graph showing excess supply of wheat and how the government will act on this
Supply will shift inwards when gov buy wheat, so supply is reduced and price rises
241
