Vazeni kolegovia,
pozyvame Vas na seminar Centra pre ekonomiu a financie Fakulty matematiky,
fyziky a informatiky Univerzity Komenskeho. Jeho obsahom bude prednaska
Ales Cerny (City University London):
Admissible strategies for semimartingale portfolio selection,
ktora sa uskutocni v piatok 12.3.2010 o 14:00 hod.(upozornujeme na zmenu dna zo standardnej stredy na piatok a tiez na zmenu hodiny na 14:00)
v poslucharni C na FMFI UK.
Abstrakt prednasky:
The choice of admissible trading strategies in mathematical modelling of financial markets is a delicate issue, going back to Harrison and Kreps (1979). In the context of optimal portfolio selection with expected utility preferences this question has been a focus of considerable attention over the last 20 years.
We propose a novel notion of admissibility that has many pleasant features -- admissibility is characterized purely under the objective measure $P$; the wealth of any admissible strategy is a supermartingale under all pricing measures; local boundedness of the price process is not required; neither strict monotonicity, strict concavity nor differentiability of the utility function are necessary; the definition encompasses both the classical mean-variance preferences and the monotone expected utility.
For utility functions finite on the real line, our class represents a minimal set containing simple strategies which also contains the optimizer, under conditions that are milder than the celebrated reasonable asymptotic elasticity condition on the utility function.

Taktiez Vam davame do pozornosti oznam o prednaske nobeloveho laureata Roberta Mundella na Ekonomickej univerzite:
-------------------------------------------------------------------
Dobry den,
Chceli by sme dat do pozornosti prednasku profesora Roberta Mundella 10.3. o 14:00 na Ekonomickej unverzite v aule, ktoru organizuje Virtual Scientific Laboratories a Nadacia Tatrabanky.
Miesta treba zaujat 20 minut pred prednaskou, dakujeme.
10.3 od 17:00 do 19:00 organizujeme Workshop na temu "Workshop o Potencialnych Hrozbach pre Europsku Menovu Uniu" v Hoteli Devin s profesorom Robertom Mundellom.
Ak mate zaujem zucastnit sa na Workshope prosim potvrdte svoju svoju ucast na emailovej adrese
kovac@elec.gla.ac.uk do 5.3.2010.
S pozdravom
Urban Kovac
