In 2 applications we demonstrate that there is empirical support for the new forms of fixed effects and a (two-way) fixed effects estimators lead to inconsistency. The icing on the cake is a comprehensive list of available packages in #Stata and #R.

We further discuss how to identify the type of unobserved heterogeneity using tests for cross-section dependence, direct tests for interactive fixed effects and the estimation of the number of factors.

We cover estimators such as the Principal Component/Iterative fixed effects estimator, the common correlated effects estimator, two stage IV estimator, group fixed effects estimator and the latest contributions to non-separable fixed effects.

Together with Y. Karavias, I am reviewing the literature not only on interactive fixed effects, but also on grouped and non-separable fixed effects with practitioners in mind.

It is terrible and unbelievable that Microsoft makes one pay (indirectly) for it. I tried it multiple times to create code or translate slides. The code was just wrong and the translation summarized slides wrongly despite me prompting not to do it. The free ChatGPT did it without probs....

Es gibt bereits eine Verbindung München nach Bologna/Verona/Venedig. Seit kurzem werden OEBB Wagen eingesetzt welche recht bequem sind. Problem: die Verbindung ist chronisch verspätet. Wahrscheinlich hat sie immer niedrigste Priorität....
