L6 HW : Food Prices, Supply and Demand

Dear Lower Sixth




You lucky things.  Now you have the secret, the keys that unlock all the mysteries of the world : how prices are determined, using diagrams which are at once elegant and powerful.

Not that you need any encouragement to apply them to all kinds of scenarios, draw these four having read the article. You need to show the old equilibrium and the new one too!

Food Prices To Soar After Mass Animal Slaughter:

a) Draw a S&D  diagram to show the effects  of the drought on animal feed prices
b) Draw a diagram to show the effects of this increase in animal feed prices on the price of pigs
c) Draw a S&D diagram to show the effects of the decision by farmers to slaughter more pigs on the price of pork in the short run
d) Draw a S&D diagram to show the effects of reduction in the number of pigs on farms  on the price of pork in the long run


Success criteria : labelled correctly, show change in S or D ; correct elasticity of S and D ; show change in price

S&D DIAGRAMS ARE WORSE THAN STDS

Hello.

Yes, a challenging HW. Draw Supply and Demand. Then draw either a new supply curve ( a shift up or down) or a new demand curve ( a sift left or right). The new equilibrium price will be where the new S or D curves crosses the original S or D curve. You can do it! Have a go!

I love the comment, "i forgot i" - how does one forget oneself?

Lads, if you've tried your best, you'll not be in any trouble. It was challenging - challenging is how this course rolls! (rolls = operates, according to the BrownBerry)

S&D = search and destroy?
