Abstract
The purpose of this paper is to highlight the superiority of the Kalman filter over Ordinary Least Squares for estimating the unknown coefficients of the classical linear regression model. Both methods are analyzed with respect to their optimality properties and their usefulness in dealing with multicollinearity. Theoretical results are applied to two economic models.
