Question
The demand for a commodity is given by Q = 30 +3₁P+u, where Q denotes quantity, P denotes price, and u denotes factors other than price that determine demand. Supply for the commodity is given by Q = % + v, where u denotes factors other than price that determine supply. Suppose that u and v both have a mean of zero, have variances o and o2, and are mutually uncorrelated. Solve the two simultaneous equations to show how Q and P depend on u and v.
