Nettetmodel with an additive unobserved effect. Somewhat surprisingly, adding the time average of the covariates (averaged across the unbalanced panel) and applying either pooled OLS or random effects still leads to the fixed effects (within) estimator, even when common coefficients are imposed on the time average.
