PROBLEM (5) Cars (x) is a normal good, and public transportation (y) is a substitute for cars. The demand for cars(x) is given by where Qp = 20 ± px ± py ± pfuture + I where px is the price of cars, py is the price of public transportation, pfuture is the expected future price of cars and I is the average income level. (a) Decide whether a plus (+) or a minus (-) sign is appropriate for each "+" in the demand equation above. (b) Does the demand become more or less elastic (at a given px) as py increases? (c) Calculate the cross price elasticity of demand (for cars with respect to the price of public transportation py) at the point I = 10, px = 5, Py = 2, pfuture = 1 (d) If the point in (c) is the market equilibrium point where the supply is known to have constant price elasticity with E = 2 at any point on the curve, derive the supply function.
