Welcome to my homepage!

I am a Professor in the Finance Group of Berlin's Humboldt University.

I received my "Habilitation" in the year 2007 at the University of Vienna. From 2007 to 2011, I taught at MIT's Sloan School of Management, and at Vienna's Institute for Advanced Studies.

These pages contain information about my academic research and teaching, as well as my applied work.

My main responsibility in teaching are courses on asset pricing and portfolio management at the bachelor and master level. Before moving to Berlin, I taught similar courses at MIT. To stay up-to-date, I regularly co-organize a conference on portfolio management.

My academic research concerns financial markets as a part of the economy that affects non-financial markets, such as product or labor markets. Here is a list of my research areas and abstracts of some representative contributions.

Finance & product markets:

In this area, a representative contribution is my analysis of the effect of the maturity structure of a firm's debt on its output pricing, i.e. the dynamic limited liability effect. The analysis shows that firms lower their prices prior to an increase in the amount of debt due. They do so in order to increase their exposure to demand shocks. The additional exposure raises the value of the option to default on debt obligations.

Finance & labor markets:

In this area, a recent working paper shows that the risk exposure of a firm's owners and workers depends on the way competing firms respond to productivity shocks by changing the scale of their output. Competitor inflexibility appears to be a risk factor: the sales of firms with more inflexible competitors respond more strongly to aggregate sales shocks. As a consequence, competitor inflexibility also affects the stability of firms' total wage- and dividend-payments. Firms with relatively flexible competitors appear to smoothen both wages and dividends, but an increase in competitor inflexibility is associated with less dividend-smoothing and more wage-smoothing.

Finance & politics:

In this area, a representative contribution is a (forthcoming) paper analyzing government-owned banks' government financing. We analyze government-owned banks' lending to their owners, using data about banks that are all owned by similarly structured local government in a single country (Austria). The analysis yields evidence that such lending was used to transfer revenues from the banks to the governments. Some of the evidence is particularly pronounced in localities where incumbent politicians face significant competition for reelection.

My academic research is closely linked to my interests in applying finance theory in consulting/policy work.
