The output gap plays an important role in the assessment and conduct of monetary policy. Most of the current literature, however, relies on filtering procedures which use ad hoc smoothness arguments for identification. Furthermore, they are subject to end-of-sample problems and do not provide...

The paper proposes an approach to evaluate hypotheses about transition dynamics when only the distributions at two points in time are observed. Using principles of statistical mechanics, we show how to adjust in the "most probable" way a hypothesis such that it becomes compatible with the...

We propose an approach to measure the mobility immanent in regular Markov processes. For this purpose, we distinguish between mobility in equilibrium and mobility associated with convergence towards equilibrium. The former aspect is measured as the expectation of a functional, defined on the...

Der Aufsatz bietet eine Zusammenfassung der theoretischen Grundlagen der linearen Kleinst-Quadrate-Prognose im Kontext von stationären Prozessen, insbesondere im Zusammenhang von ARMA bzw. ARMAX Systemen. In einem ersten Schritt wird das Prognoseproblem unter der Voraussetzung, dass die zweiten...
