Firms are increasingly becoming interested in harnessing the potential of online social networks for marketing purposes. Marketers are therefore interested in understanding the antecedents and consequences of relationship formation within such social networks and in predicting the interactivity among users. In this paper we develop an integrated statistical framework for...

Damit die Schweiz weiterhin in der Weltspitzengruppe der Nationen mit hoher Innovationsneigung präsent sein wird,
muss sie auch als Wissens- und Denkplatz attraktiv bleiben. Dies bedingt, wie im folgenden Beitrag aufgezeigt wird, einen
offenen Arbeitsmarkt.

Die demografische Alterung wird in der langen Frist erhebliche Anpassungen in der Finanzierung der Altersvorsorge erfordern. Die Art und Weise, wie die Finanzierungslücke geschlossen wird, hat beträchtliche Auswirkungen auf den Arbeitsmarkt. Für die zukünftige Entwicklung des Pro-Kopf-Einkommens ist es entscheidend, dass die Finanzpolitik in einer Weise reagiert, welche die Anreize...

Using a Switzerland-specific Carhart model, we study the risk-adjusted performance of actively and passively managed mutual funds investing in Swiss stocks from 1989 to 2007. We also compare the performance of actively managed funds to passively managed funds instead of comparing them to a theoretical index. For a sample of 160 funds with 13'672 monthly observations we find that...

Models for hysteresis in continuum mechanics are studied that rely on a time-discretised quasi-static evolution of Young measures akin to a gradient flow. The main feature of this approach is that it allows for local, rather than global minimisation. In particular, the case of a non-coercive elastic energy density of Lennard-Jones type is investigated. The approach is used to...

A new class of risk measures called cash sub-additive risk measures is introduced to assess the risk of future financial, nonfinancial and insurance positions. The debated cash additive axiom is relaxed into the cash sub-additive axiom to preserve the original difference between the numeraire of the current reserve amounts and future positions. Consequently, cash sub-additive risk...
