What Is Orthogonality In GMM? In this informative video, we will discuss the concept of orthogonality in the Generalized Method of Moments (GMM) and its significance in econometric modeling. We will explain what orthogonality means in the context of moment functions and error terms, and how this relationship is critical for estimating parameters in economic models. You’ll learn about the role of moment conditions derived from economic theory and how they contribute to unbiased and consistent parameter estimates.

Additionally, we will explore the two main scenarios in GMM related to orthogonality: the just-identified case and the over-identified case. Understanding these scenarios will help clarify how economists can estimate parameters without needing to fully define the data-generating process. We will also touch on the implications of rational expectations and how they relate to the orthogonality condition.
