Fixed effects random effects

Webthe random effects model leads to the same estimators as the fixed effects model in situations where the individual effects are correlated with the exogenous variables and thus, in these hardly unusual circumstances, the fixed effects model assumes paramount importance.5 Unfortunately, as the Monte-Carlo work of Nerlove [12, 13] makes clear, the http://charlotte-ngs.github.io/2015/01/FixedVsRandom.html

WebThe use of fixed (FE) and random effects (RE) in two-level hierarchical linear regression is discussed in the context of education research. We compare the robustness of FE models with the modelling flexibility and potential efficiency of those from RE models. We argue that the two should be seen as complementary approaches. Webrepresents a large effect for the fixed effects. For random effects, they suggest .05, .10, and .15 should be used for small, medium, and large effect sizes (based on variance values for a standard normal variable).

It takes off the mean from each group and the only variation leftover to estimate β is time series variation within each firm. If the fixed effects can be anything, this is what you have to do.
