Suppose silver (S) and gold (G) are substitutes for each other
because both serve as hedges against inflation. Suppose also that
the supplies of both are fixed in the short run (QS= 250 and
QG=150) and that the demands for silver and gold are given by the
following equations:
PS=600-QS+0.5PG
PG=1050-QG+0.5PS
What are the equilibrium prices of the silver and gold?
What if a new discovery of gold doubles the quantity supplied to
300. How will this discovery affect the prices of both silver and
gold?
