Assume a market has the following demand
and supply functions:
Qp = 28-3P
Qs = 2P-12
Where P is the price
a)
Determine algebraically the equilibrium price
and quantity.
b)
Plot the demand and supply curves and
confirm your answer.
Suppose supply shifts to Qs =2P – 2 with no
change no change in demand. Determine the new
equilibrium price and quantity.
d) Although the supply curve shifts to the right
by 10, the quantity exchanged does not rise by 10,
explain why the increase in quantity is smaller.
