We are proudly announcing the following talk: Thursday, Sept 7, 2000 FAM-ily's Seminar Room at 16:30 (Freihaus, 7th floor) Thomas Goll: Optimal portfolios for logarithmic utility Abstract We consider the problem of maximizing the expected logarithmic utility from consumption or terminal wealth in a general semimartingale market model. The solution is given explicitly in terms of the semimartingale characteristics of the securities price process.
