Description
English: Comparison between the Fixed Effects (FE) and the Random Effects (RE) estimator in a situation where the assumptions of the Fixed Effects model hold. Using Stata, I created an artificial panel data set of 2 time periods and 1000 observations that satisfies the FE assumptions, simulated 1000 Fixed Effects and Random Effects estimations and plotted an estimate of the density functions of the two estimators. As can be seen, only the distribution of the FE estimator is centered around the true underlying parameter value 5, the RE estimator is inconsistent. The graph and all simulations were created with Stata 10.
Deutsch: Vergleich zwischen dem Fixed-Effects- und dem Random-Effects-Schätzer in einer Situation, in der die Annahmen des Fixed-Effects-Modells gelten. Ich benutzte Stata, um ein künstliches Paneldatenset mit 1000 Beobachtungen und 2 Zeitperioden zu kreieren und simulierte dann 1000 FE- und RE-Schätzungen. Anschließend wurde eine Schätzung der Dichtefunktionen der beiden Schätzer geplottet. Wie zu erkennen ist, ist nur die Dichtefunktion des FE-Schätzers um den wahren Parameterwert 5 zentriert, der RE-Schätzer ist nicht konsistent. Die Grafik und alle Simulationen wurden mit Stata 10 erstellt.
