Die vorliegende Arbeit stellt das Unternehmensbewertungsproblem konsequent als individuelles Entscheidungsproblem über Kauf oder Nichtkauf bzw. Verkauf oder Nichtverkauf in ein Finanzmarkt-Umfeld. Insofern werden daher Induvidualkalkül und Marktbewertung in einer Sichtweise integriert.

The option pricing model by Black and Scholes (1973) and the term structure model by Ho and Lee (1986) are among the most influential models of capital market theory. (...)

Today's primarily mathematically oriented arbitrage theory does not address some economicallyimportant aspects of pricing. These are, rst, the implicit conjecture that thereis \the" price of a portfolio, second, the exact formulation of no{arbitrage, price reproduction,and positivity of the...

Die vorliegende Arbeit versucht, die zentralen ökonomischen Aussagen der Bewertungstheorie in einem einfachen einperiodigen Modell darzustellen.

The present paper employs the general method of stochastic discounting to show how models of the term structure of interest rates may be developed. (...)

The present paper extensively studies Gaussian term structure and interest rate models in the perspective of stochastic discounting. Related issues such as consistent stock price models and option prices are also discussed

The paper gives a slightly generalised version of the well-known Ho-Lee-model of the term structure of interest rates. The Ho-Lee-model is reconstructed by the method of stochastic discounting; continuous time limits are considered which are parallel to the work of Heath, Jarrow and Morton. In...
