This response will be about falling inflation. So I'm hoping to find some information on perhaps why it is falling, to what extent the government played a part, and what might the consequences be?
I can now bring in monetary policy and explain not only why a government may wish to lower interest rates (to boost AD) but also how a lowering of inflation might allow this situation.
Could also do some evaluation to suggest that cost-push disinflation is better to have than demand-pull disinflation, as with cost-push disinflation you still get GDP growth.
So the only way this can be explained is that demand has increased more than the increase in supply, therefore leading to a 'rocketing' in prices. Again, would be good if I could explain why.
"It's being used as mayonnaise, in margarine, salads, anywhere vegetables are used. It has a good health profile, has low saturated fat, is high in omega-3, and some claim it is better than sunflower oil," he say
Other places like Germany, Poland and Ukraine have had a dreadful winter, the crops were exposed to severe cold temperatures, I suspect the French suffered as well.
I can bring in here the concept of substitute goods - that German etc rape crops are a substitute good. That their fall in supply will have lead to an increase in the price for them, leading to a fall in demand. This will have lead to an increase in demand for UK rape crops. Could show this diagrammatically if needed.
and they are 45% oil - and the other 55% is high protein animal feed - they are an amazing piece of nature," he says.
Burnett says oilseed rape is also being used for biodiesel, while a very small amount has specialist industrial uses, for instance as lubricants.
Again, this explains the surge in demand. It has a number of different uses. (Called composite demand).
Burnett says oilseed rape has probably been more visible this year because it has flowered for almost twice its normal length of time - eight weeks, instead of four - as a cold and wet April and May stopped flowers developing and dying at their normal rate.
So, overall, I could write a commentary about how a small shift in supply and a large shift in demand has led to an increase in the price for rape seed. I can easily show this with a diagram and explain the factors behind each movement. I would need to show the shift in supply being less than the shift in demand. For evaluation I could start to look at the impacts of PED and PES. Might they be inelastic or elastic and how might this impact the price mechanism. I could also speculate a little about what might happen in the future, based on the information in the article, and its impact on the price of rape seed in the UK
