Information search is the process of seeking, finding, and evaluating information to fulfill a specific need or solve a problem. It involves cognitive, behavioral, and technological strategies to efficiently locate relevant data and insights within vast information landscapes.
Relevant Fields:
The Generalized Method of Moments (GMM) is a statistical estimation technique that uses sample moments to estimate the parameters of a model, providing a flexible framework that can accommodate a wide range of economic models and data structures. GMM is particularly useful when the model is overidentified, meaning there are more moment conditions than parameters to estimate, allowing for robust inference even with potential model misspecification or heteroskedasticity in the data.
