Method Main Use Case Assumptions Handles Time-Invariant Variables Endogeneity Control When to Use Pooled OLS Treats panel data as pure cross-sectional data Assumes no unobserved heterogeneity (all units are identical aside from included variables)...
One should use Generalized Method of Moments (GMM) when: 1. Endogeneity is present GMM is commonly used to address endogeneity, especially when: 2. Model has more moment conditions than parameters GMM allows estimation even...
An instrumental variable (IV) is a tool used in regression analysis to solve the problem of endogeneity — when an explanatory variable is correlated with the error term. A good instrument must satisfy two...
Endogeneity refers to a situation in which an explanatory variable is correlated with the error term in a regression model. This violates a key assumption of classical linear regression and leads to biased and...
“Long-run equilibrium” in the context of cointegration means: Even though individual time series (e.g., prices, GDP, exchange rates) may drift or trend over time, a certain linear combination of them remains stable over the...
