We prove a version of the Fundamental Theorem of Asset Pricing, which applies to Kabanov's approach to foreign exchange markets under transaction costs. The financial market is modelled by a d x d matrix-valued stochastic process Sigma_t_t=0^T specifying the mutual bid and ask prices between d...

We analyse questions of arbitrage in financial markets in which asset prices change in time as stationary stochastic processes. The main focus of the paper is on a model where the price vectors are independent and identically distributed. In the framework of this model, we find conditions that...

We study arbitrage opportunities in diverse markets as introduced by R. Fernholz in [2]. By a change of measure technique we are able to generate a variety of diverse markets. The construction is based on an absolutely continuous but non-equivalent measure change which implies the existence of...

Der vorliegende Beitrag untersucht die Determinanten der Performance europäischer ArbitrageCollateralized Loan Obligations für das Jahr 2009. Der Fokus liegt dabei auf der Bedeutung derperformanceabhängigen Vergütung des CLO-Managers, den Eigenschaften des CLO-Managersund der...

Wir untersuchen eine Gewinnsteuer in einer unsicheren Welt. Unser Steuersystem erlaubt einen zeitlich veränderlichen Steuersatz, aus diesem Grund wurde auch eine verallgemeinerte Zinskorrektur (ACE) eingeführt. Die Zinskorrektur ist insofern verallgemeinert, da sie einen Anteil des Produktes...

In a recent paper Loeffler/Schneider (2000) showed that introducing a tax on a financial market does not create an arbitrage opportunity...

This paper develops a new estimation procedure for characteristic-based factor models of security returns. We treat the factor model as a weighted additive nonparametric regression model, with the factor returns serving as time-varying weights, and a set of univariate non-parametric functions...

There is an extensive literature claiming that it is often difficultto make use of arbitrage opportunities in financial markets. Thispaper provides a new reason why existing arbitrage opportunitiesmight not be seized. We consider a world with short-lived securities,no short-selling constraints...
