Anfang des neuen Jahrtausends schien es so, als ob die Einführung elektronischer Wahlenin Deutschland kurz bevor stehen würde. Der damalige Bundesinnenminister Schilywar der festen Überzeugung, dass spätestens zu den Bundestagswahlen 2006 neben derStimmabgabe an der Urne und per Brief auch...

Neoclassical economic theory rules out systematic errors in consumptionchoice. According to the basic view, individuals know what they choose. They areable to predict how much utility an activity or a good produces for them now and inthe future and they can maximize their utility. This implies...

People not only obtain utility from actual outcomes but also from the conditionswhich lead to these outcomes. The paper proposes an economic concept of this notion ofprocedural utility. Preferences beyond outcome can be manifold. We distinguish proceduralutility people get from institutions as...

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 the exponential utility indifference valuation of a contingentclaim H when asset prices are given by a general semimartingale S. Under mildassumptions on H and S, we prove that a no-arbitrage type condition is fulfilled ifand only if H has a certain representation. In this case, the...

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...

We consider a cooperative model of bargaining where the location of thedisagreement point may be uncertain. Based on the maximin criterion, we formulate anex ante effciency condition and characterize the class of bargaining solutions satisfyingthis axiom...

Der deutsche Einzelhandel befindet sich jetzt schon seit längerer Zeit in einerschwierigen Lage: Die Umsätze stagnieren, der Anteil des Handels an der Gesamtkaufkraftsinkt. Die Unternehmen reagieren bislang überwiegend mit Beschäftigungsabbauund versuchen darüber hinaus höher durch...
