The transmission of monetary and fiscal policies in an international context is one of the most prominent topics in the realm of international finance. In particular, researchers are interested in the effects of the respective policy on exchange rate movements, international price level...

In der vorliegenden Arbeit beschäftige ich mich mit der theoretischen Analyse von Geld- und Fiskalpolitik in Currency-Board-Systemen und der Währungsunion. Beide Währungssysteme haben seit den neunziger Jahren zunehmend an Bedeutung gewonnen, Currency Boards durch die Rückgewinnung der...

In this thesis we address problems associated with financial modelling from a Bayesian point of view. Specifically, we look at the problem of calibrating financial models, measuring the model uncertainty of a claim and choosing an optimal hedging strategy. Throughout the study, the local...

The high pace at which many of the world's energy markets have gradually been opened tocompetition have generated a significant amount of new financial activity. Both academicians and practitioners alike recently started to develop the tools of energy derivatives pricing/hedging as a...

Die vorliegende Arbeit untersucht wissenschaftlich anhand eines theoretischen Modells, wie sich internationale Migration auf die Volkwirtschaft des Aufnahmelandes auswirkt – nicht nur im Rahmen der EU-Osterweiterung. Kapitel eins enthält neben einer Hinführung zum Thema einen allgemeinen...

The tradition of gravity models is in the analysis of trade flows with market size and geographic or economic distance as core variables. Both these variables can be important determinants of FDI, too. However, when such models are used to explain FDI, there can be differences in the mode of...
