We derive the asymptotic distributions of degenerate <InlineEquation ID="IEq7"> <EquationSource Format="TEX">$$U$$</EquationSource> </InlineEquation>- and <InlineEquation ID="IEq8"> <EquationSource Format="TEX">$$V$$</EquationSource> </InlineEquation>-statistics of stationary and ergodic random variables. Statistics of these types naturally appear as approximations of test statistics. Since the limit variables are of complicated structure, typically depending on unknown...</equationsource></inlineequation></equationsource></inlineequation>

Confidence intervals for impulse responses computed from autoregressive processes are considered. A detailed analysis of the methods in current use shows that they are not very reliable in some cases. In particular, there are theoretical reasons for them to have actual coverage probabilities...

Die EU-Kommission verlangt für die Periode von 2007 bis 2013 eine Aufstockung ihres Budgets, was eine höhere Belastung der Nettozahlerländer mit sich bringen würde. Prof. Dr. Norbert Berthold und Dr. Michael Neumann, Universität Würzburg, gehen in diesem Beitrag der Frage nach, ob sich...

Um trotz der wachsenden Komplexitaet wirtschaftliche Prozesse und ethische Verpflichtungen vereinen zu koennen, ist die Zuweisung von klaren Verantwortlichkeiten unumgaenglich. Der vorliegende Beitrag diskutiert vor dem Hintergrund der Prinzipal-Agenten-Theorie sowie der Empirie aus dem Ersten...

The introduction of the minimum wage in the German painter and varnisher trade in 2003 is used as a natural experiment to study the effects of minimum wages on wages and employment. We find a significant positive effect on the average hourly wage of skilled workers in East Germany, but not in...
