Ana Marc You are making the same mistake as many other users here, i.e. In a recent paper, Yoon and Lee (2019) (YL hereafter) propose a weighted Fama and MacBeth (FMB hereafter) two-step panel regression procedure and provide evidence that their weighted FMB procedure produces more efficient coefficient estimators than the usual unweighted FMB procedure. fama macbeth rolling beta.

I think that Fama Macbeth doesn't use fixed effects and stuff, and that panel data regression is a regression with dummy variables (fixed effects), but what is the difference between the two exactly? FM cross-section regression, the enhanced version of FM panel regression assesses the impacts of oil and gas risk factors and allows for concurrent analysis of cross-sectional and time-series of the data. We rely on an improved Hausman artificial regression Y and X can be any variables. The first step which is performed as panel regression and includes an EMI (Efficient-Minus-Inefficient)-factor into the 5-factor-model (Fama and French 2018). 2.
