The main purpose of this site is to make available the research material I have produced. After spending a few years as Assistant Professor (tenure-track) at UCLA, I decided to take a decade-long break from academia to become a stock trader. I made Managing Director in a global bulge-bracket Investment Bank. I have now returned to academia as Permanent Research Fellow in the Department of Economics of the University of Zurich. I am also interested in the Gold Franc.
