Consider a product market with a supply function Qs i = b0 + b1 Pi + u s i , a demand function Qd i = g0 + u d i , and a market equilibrium condition Qs i = Qd i , where u s i and u d i are mutually independent i. i.d. random variables, both with a mean of zero. a. Show that Pi and u s i are correlated. b. Show that the OLS estimator of b1 is inconsistent. c. How would you estimate b0 , b1 , and g0 ? Stock, James H..
