Non-spherical errors, namely heteroscedasticity, serial correlation and cross-sectional correlation are commonly present within panel data sets. These can cause significant problems for econometric analyses. The FGLS(Parks) estimator has been demonstrated to produce considerable efficiency gains...

In diesem Beitrag werden die Effekte symmetrischer und asymmetrischer Besteuerung auf die Vorteilhaftigkeit erfolgsabhängiger und erfolgsunabhängiger Entlohnungsverträge untersucht. Dazu wird ein binäres Agency-Modell verwendet, in das eine proportionale Unternehmenssteuer auf Ebene des...

Der Beitrag untersucht die Vorteilhaftigkeit der Investition in private Photovoltaik-Aufdachanlagen (PV-Anlagen). Die Förderung durch das Energieeinspeisegesetz (EEG) bei Einspeisung des selbsterzeugten Stroms in das öffentliche Stromnetz sowie die hohen Vergütungssätze für den...

We analyze competitions where the contestants evaluate each other and find the first contestant to be disadvantaged. We suspect that this is due to information diffusion, Bayesian belief updating taking place in course of the contest and initial uncertainty about a contestant's relative quality.

Recent research has shown that optimal monetary policy may display considerable price-level drift. Proponents of price-level targeting have argued that the costs of eliminating the price-level drift may be reduced if the central bank responds flexibly by returning the price level only gradually...

We show that including distribution costs into a general equilibrium model of international portfolio choice contributes to explaining the 'home bias' in international equity investment. Our model is able to replicate observed investment positions for a wide range of parameter values, even if...

We demonstrate the possibility of indeterminacy and non-existence of equilibrium dynamics in a standard business cycle model with search and matching frictions in the labor market. Our results arise for empirically plausible parametrizations and do not rely upon a mechanism such as increasing...

This paper shows the strategic aspects of international outsourcing in an oligopolistic market, if outsourcing is attractive because of fixed cost savings. We show that outsourcing decisions are strategic substitutes. Furthermore, we demonstrate that due to decreasing individual output,...
