Basic Econometrics - Unbiasedness and consistency of OLS

This video is part of an online module for my course Basic Econometric at University of Gothenburg, Sweden. In this video, I remind you that estimators are computed on random samples and are therefore interpreted as a random variable. I explain how to investigate the randomness of the estimator using a simulation experiment. We discuss two properties of the OLS estimator: unbiasedness and consistency.
