Based on the APARCH model and two outlier detection methods, we computereliable time series of volatility asymmetry for 49 countries with relatively few ob-servations. Results show a steady increase in the asymmetry over the years for mostcountries. We nd that economic development and market...

We analyze the investment behavior of private clients concerning structured products. To ascertain their stated and revealed preferences, we use a questionnaire and a field experiment, respectively. The real product issued in the field experiment is comparable to one product in the questionnaire...

We analyse questions of arbitrage in financial markets in which asset prices change in time as stationary stochastic … framework of this model, we find conditions that are necessary and sufficient for the absence of arbitrage opportunities. We …

Like many financial contracts, derivatives are subject to default risk. A very popular mechanism in derivatives markets to mitigate the risk of non-performance on contracts is margining. By attaching collateral to a contract, margining supposedly reduces default risk. The broader impacts of the...

Credit limit management is of paramount importance for successful short-term credit-risk management, even more so when the situation in credit and financial markets is tense. We consider a continuous-time model where the credit provider and the credit taker interact within a game-theoretic...

Most derivative contracts are traded over-the-counter, i.e., bilaterally between two counterparties. Recently, clearing services have become available that allow to transfer over-the-counter derivatives to a central counterparty (clearing house). We develop a framework to determine the effects...

In this paper we construct arbitrage-free market models of stochastic volatility type for one stock, one bank account … of dynamic arbitrage in the market can be characterized in terms of drift restrictions on the model coefficients. Most … provide a class of explicit examples satisfying the no-arbitrage conditions. This allows us to construct arbitrage-free multi …

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...

We prove that under very weak conditions optimal financial products have to be co-monotone with the inverted state price density. Optimality is meant in the sense of the maximization of an arbitrary preference model, e.g. Expected Utility Theory or Prospect Theory. The proof is based on methods...
