Der Artikel liefert einen Einblick in die wirtschaftswissenschaftliche Sichtweise der Terrorismusforschung und versucht Aspekte der zukünftigen Entwicklung zu beleuchten. Dabei werden Konzepte des Angebots und der Erträge terroristischer Aktivitäten beschrieben und Ansatzpunkte einer...

Die Verlagerung von der ambulanten zur stationären Pflege ist eine der Hauptursachen für die Ausgabensteigerungen der gesetzlichen Pflegeversicherung. Um diesen so genannten Heimsog zu reduzieren, haben die Pflegekassen ein Modellprojekt Personengebundenes Pflegebudgetinitiiert, das über ein...

Market participants often suspect that large traders have a disproportionate effect on financial markets, increasing the aggressiveness of market responses. Prior studies have shown that the impact of a large trader on a currency crisis depends positively on his size and informational position....

Although there has been much attention in recent years on the effects of additive background risks, the same is not true for its multiplicative counterpart. We consider random wealth of the multiplicative form xy, where x and y are statistically independent random variables. We assume that y is...

In this paper we propose a model for the conditional multivariate density of integer count variables defined on the set Zn. Applying the concept of copula functions, we allow for a general form of dependence between the marginal processes which is able to pick up the complex nonlinear dynamics...

This paper investigates dynamically optimal risk-taking by an expected-utility maximizing manager of a hedge fund. We examine the effects of variations on a compensation structure that includes a percentage management fee, a performance incentive for exceeding a specified highwater mark, and...

In this paper we develop a model for the conditional inflated multivariate density of integer count variables with domain Zn. Our modelling framework is based on a copula approach and can be used for a broad set of applications where the primary characteristics of the data are: (i) discrete...
