With data spanning multiple units and time periods, the fixed effects estimator is the default estimator of causal effects with linear models and nonexperimental data due to the removal of time-invariant heterogeneity. One feature of the estimator is often overlooked, however: the attributes that are time-invariant are not invariant to the length of the panel. We consider several alternatives to the fixed effects estimator with more than two time periods when relevant unit-specific heterogeneity is not time-invariant, including novel rolling estimators.
Through simulations and replications, we find little gain —and much to lose— by using the fixed effects estimator.
