Estimating Models of Supply and Demand: Instruments and Covariance Restrictions
By: Alexander MacKay and Nathan H. Miller
We consider the identification of empirical models of supply and demand with imperfect
competition. We show that a restriction on the covariance between unobserved demand and
cost shocks can resolve endogeneity and identify the price parameter. We demonstrate how
to...

a constructive identification result where the causal price parameter can be expressed as a function of the covariance of unobserved shocks. The function is estimated efficiently by the output of ordinary least squares regression. Thus,...
