Panel regression specifically analyses cross sectional time series data and incorporates these effects into the model. It also increases the sample size, which may be a trivial benefit while panel models (especiallyfixed effects) can control for unobserved heterogeneity which may be crucial. The ...
We use the cross-section regression approach of Fama and MacBeth (1973) to construct cross-section factors corresponding to the time-series factors of Fama and French (2015). Time-series models that use only cross-section factors provide better descriptions of average returns than time-series mode...
