Question:

Consider a market in which

Qd = a − bP + cM,

where Qd is quantity demanded, P is price, and M is income,

and

Qs = d + eP, (1)

where Qs is quantity supplied. Assume that a, b, c, and e are positive parameters.

1. Comment on the plausibility of d being a positive parameter in the supply schedule in (1).
2. Obtain expressions for equilibrium price and equilibrium quantity in this market. Use your expressions to determine what happens to equilibrium price and to equilibrium quantity if there is an increase in income M.
3. Explain your conclusions in (b) using a diagram with quantity on the vertical axis and price on the horizontal axis.
