Due to their indeterminacies, static and dynamic factor models require identifying assumptions to guarantee uniqueness of the parameter estimates. The indeterminacy of the parameter estimates with respect to orthogonal transformations is known as the rotation problem. The typical strategy in...

In der Augustausgabe 2015 veröffentlichte der Wirtschaftsdienst einen Aufsatz von Jens Boysen-Hogrefe und Ulrich Stolzenburg über "Rettungsprogramme und "Ownership" - Irland, Portugal und Griechenland im Vergleich". Nach der Replik von Ernst Niemeier folgt hierzu eine Erwiderung der Autoren.

We investigate whether recoveries following normal recessions differ from recoveries following recessions that are associated with either banking crises or housing crises. Using a parametric panel framework that allows for a bounce-back in the level of output during the recovery, we find that...

Due to their well-known indeterminacies, factor models require identifying assumptions to guarantee unique parameter estimates. For Bayesian estimation, these identifying assumptions are usually implemented by imposing constraints on certain model parameters. This strategy, however, may result...
