This paper presents a survey on panel data methods in which Iemphasize new developments. Inparticular, linear multilevel models with a new variant are discussed. Furthermore, non-linear, nonparametric and semiparametric models are analyzed. In contrast to linear models there do not exist unified...

The combination of enterprises is not a phenomenon of the last years. The concept of the "Mergers & Acquisitions" is based on fundamental economic theories, which are however often overlaid in the discussion by populist motives for the merger or acquisition in that particular case. This article...

This paper discusses the existence of spurious long memory in common nonlinear time series models, namely Markov switching and threshold models. We describe the asymptotic behavior of the process in terms of autocovariance and autocorrelation function and support the theoretical evidences by...

This paper offers new insights into the Italian mutual fund industry. Surveying Italian professionals, we do not only reveal typical gender differences but also detect divergence to their German counterparts. While disclosing Italian professionals’ overly positive self-assessment in general,...

Except for special cases, passport option s do not have closed-form solutions. Here we show how to derive approximate solutions using finite element methods. We also show that finite elements offer advantages in computing the hedge parameters.

This paper provides a unified growth theory, i.e. a model that explains the very long-run economic and demographic development path of industrialized economies, stretching from the pre-industrial era to present-day and beyond. Making strict use of Malthus' (1798) so-called preventive check...
