Abstract In den Jahren 1983-1987 erlebte der deutsche Aktienmarkt eine Going-Public-Welle. Die durchschnittliche Differenz zwischen Emissionspreis und erstem Börsenpreis betrug dabei ca. 20 °/o. Diese in der Literatur als Underpricing-Phänomen bezeichnete Beobachtung wird im vorliegenden...

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

Temporal disaggregation methods are used to disaggregate low frequency time series to higher frequency series, where either the sum, the average, the first or the last value of the resulting high frequency series is consistent with the low frequency series. Temporal disaggregation can be...

Based on a relative entropy approach, this paper proposes a method to estimate or update transition matrices using just cross-sectional observations at two points in time. The method is then applied to explain the development of the US income distribution. Starting from three hypothesized...

We propose an approach to measure the mobility immanent in 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 Cartesian...

This paper proposes to measure the mobility of a stochastic process as the expected value of a "mobility functional" with respect to its stationary distribution. The mobility functional thereby measures the valuation of movements between states. We not only highlight the conceptual advantages of...

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...
