From June 2014 to January 2016 the price of crude oil
collapsed from $115 to $27 per barrel. The supply and demand model
says there are two basic reasons for the price of any item to
fall.
A) In two graphs, draw an arbitrary supply and demand curve in
each for oil, and then (with arrows and a new shifted curve) show
one reason in one graph, and the other reason in the next
graph.
B) Another major event that happened over the same period was
the collapse of commodity and equity markets. Over the same period
the Toronto Stock Market Index (TSX) fell from about 15,000 to
13,000 points. Given this information, which of the above reasons
do you think is most likely the cause of the fall in the price of
oil?
C) Of the two reason for the price of oil you identified,
which one is likely to be correlated with economic growth and which
one with economic decline?
D) Over this same period of time, something was happening to a
very big economy on the other side of the world. What and how would
this fit into the puzzle of falling oil and commodity price.
