Ordinary least squares (OLS) is often used for estimation since it provides the BLUE or "best linear unbiased estimator" (where "best" means most efficient, unbiased estimator) given the Gauss-Markov assumptions.
Larger coefficients (economically) or flipped sign when using fixed effects instead of OLS?
Yearly there's a festival, in which all 160 of them compete for the highest honours to be gained, in the "OLS" (Oud Limburgs Schuttersfeest), which is held in either a place in Belgian Limburg or in Netherlands' Limburg.
While it does not bias the OLS coefficient estimates, the standard errors tend to be underestimated (and the t-scores overestimated) when the autocorrelations of the errors at low lags are positive.
This is especially noticeable in the 8 core test where OLS 1.4.16 briefly reaches 200,000 requests per second and shortly thereafter returns to our limit of 100,000 requests per second.
