QUESTION 1
1. Supply and Demand, Elasticity
Consider the market for butter. The demand curve is given by
QD = a+ b x P + cx I,
where I is the average income and Pis the price of butter. The supply curve is
Q° = d x P + e x Pm + f.
where Pm is the price of milk.
At above: a=250, b=-2, c=4, d=6, e= -20, and f= -20.
