Talks: ------ (Please see http://www.math.ethz.ch/finance/talks.html for links)

(a) Thursday, November 29, 2001, 15.15 h (ETHZ, HG E42)

Dr. Thorsten Rheinländer (Department of Mathematics, ETH Zürich) "A martingale duality approach to stochastic volatility models"

Abstract: We discuss the valuation of derivatives in a general stochastic volatility context. The fact that the volatility typically is unbounded already rules out several well known approaches to valuation in incomplete markets. It turns out that it is still possible to follow a minimal entropy approach. We determine explicitly the resulting pricing measure for some classical stochastic volatility models and provide general verification results.

(Seminar on Financial and Insurance Mathematics)

(b) Wednesday, December 5, 2001, 20.00 h (Restaurant Au Premier, Zürich Main Station)

Jean-Luc Vuarnoz (Swiss Life) "Underwriting und Antiselektion in der Personenversicherung"

Abstract: Anhand zahlreicher Beispiele aus der Praxis wird die Antiselektion illustriert. Die Zusammenhänge zwischen Antiselektion und Produktdesign einerseits und Risikoprüfung andererseits werden verdeutlicht. Kommende Herausforderungen im Gebiet Risikoprüfung, z.B. Internet-Verkauf und Gentests, werden kurz diskutiert.

(Colloquium of Actuaries)

(c) Thursday, December 6, 2001, 17.15 h (ETHZ, G 26.5)

Prof. Christophe Stricker (Université de Franche-Comté, Besançon) "The fundamental theorem of asset pricing under proportional transaction costs"

Abstract: We consider a multi-asset discrete-time model of a financial market with proportional transaction costs and efficient friction and prove necessary and sufficient conditions for the absence of arbitrage. Our main result is an extension of the Dalang-Morton-Willinger theorem. As an application, we establish a hedging theorem giving a description of the set of initial endowments which allow to super-replicate a given contingent claim.
