We propose an experimental design allowing a behavioral test of the axiom ofcompleteness of individual preferences. The central feature of our design consistsin enabling subjects to postpone commitment at a small cost. Our main result isthat preferences are significantly incomplete. We use...

We study the exponential utility indierence value h for a contingentclaim H in an incomplete market driven by two Brownian motions.The claim H depends on a nontradable asset variably correlated withthe traded asset available for hedging. We provide an explicit se-quence that converges to h,...

We consider backward stochastic dierential equations (BSDEs) witha particular quadratic generator and study the behaviour of their solu-tions when the probability measure is changed, the ltration is shrunk,or the underlying probability space is transformed.[...]

We study utility indifference pricing of claim streams with intertemporalconsumption and power (CRRA) utilities. We derive explicit formulasfor the derivatives of the utility indifference price with respect toclaims and wealth. The simple structure of these formulas is a reflectionof surprising...

Die vorliegende Arbeit behandelt die Markterfolge japanischer Unternehmen - Arrangements zwischen staatlichen Agenturen und kooperierenden Konkurrenten, Banken und Wissenschaft waren offensichtlich in der Lage, durch konzertierte Abstimmungen langfristige Strategien eines gezielten Einbruchs in...

Ursprünglich sollte diese Studie eine vorwiegend empirische Bestandsaufnahme des soziokulturellen Strukturwandels und des touristisch induzierten Wandels auf der Mikroebene der Insel S.te Marie vermitteln - eine weitreichende Sichtung der theoretischen Forschung hat jedoch die Bedeutung einer...

Community support and (location-based) mobile services are two prominent topics in research and development currently. However, they are usually not combined - there is little work on mobile community support services.(...)
