Welcome to my homepage!

I am a Professor of Finance at the School of Economics and Business of Berlin's Humboldt University.

I graduated from the University of Vienna, where I also obtained my "Habilitation" in the year 2007.

From 2007 to 2011, I taught at the Institute for Advanced Studies in Vienna, and at MIT's Sloan School of Management. In 2011, I moved to Berlin.

Here is a link to Humboldt's finance group. I'm also affiliated with the Vienna Graduate School of Finance (VGSF), and the European Corporate Governance Institute (ECGI).

Research interests and representative contributions:

I view finance as a field analyzing the allocation of risk in society. Risks have direct effects on economic agents, as well as indirect effects that exist because agents are affected by other agents' responses to risks. The existence of indirect effects often complicates the measurement of the direct effect.

Weather risk is a risk factor with relatively clear-cut direct effects. My research analyzes effects of weather risk on the Austrian tourism industry. This risk is a risk of demand shocks. It mainly affects family-owned businesses and their bank creditors. The direct effects depend on the capital structure of the businesses, while indirect effects are associated with banks' responses to weather shocks. I've analyzed both types of effects in two papers that appeared in The Review of Financial Studies.
Competitive risk is risk associated with competitor behavior. I'm particularly interested in situations in which a firm's risk exposure depends on the way competing firms respond to risk factors. My work analyzes how competitive risk affects' firms' owners and employees, as well as their creditors.
Political risk is a new research interest of mine. A recent paper analyzes effects of political instability on government-owned banks, based on data about Austrian municipally-owned savings banks. We find evidence that the banks' lending to their owners was used to transfer revenues from the banks to the governments. Some of the evidence is particularly pronounced in localities where the incumbent politicians face significant competition for reelection. [link to the paper]
