st: How is the pooled OLS corrected for heteroschedasticity different from the FE model

Dear Statalist,
I am having trouble differentiating pooled OLS corrected for
heteroschedasticity and the FE model. Why are these two different? It
seems to me that both are same in that they try to control for
unobserved cross-sectional heteroschedasticity. If so, why is the FE
model considered to be superior to the heteroschedasticity-corrected
pooled OLS model?
Thank you very much and I would deeply appreciate any help.
Sincerely with Many Thanks,
Haillie Lee
