Modellierung der Abhängigkeiten zwischen Ausfall, Verlustrate und Forderungshöhe bei Ausfall mit Faktoren und Copulae -- Multivariate Erweiterung des Heckman-Schätzers, um der Stichprobenselektion seitens der Verlustrate und der Forderungshöhe gerecht zu werden -- Empirische Befunde zur...

The finance literature looks at a number of factors to explain risk premia in corporate debt, such as liquidity effects, jump-to-default risk, and contagion risk. Stochastic recovery rates as a source of systematic risk have not received much attention so far, most likely due to the difficulties...

Credit Risk Measurement in the Context of Basel II -- Concentration Risk in Credit Portfolios and Its Treatment Under Basel II -- Model-Based Measurement of Name Concentration Risk in Credit Portfolios -- Model-Based Measurement of Sector Concentration Risk in Credit Portfolios -- Conclusion

Since Thaler (1981), we have lived with the uncomfortable stylized fact that many humans choose strictly dominated actions in intertemporal choice experiments. We designed an experiment to probe the reasons for the apparently suboptimal behavior, and we find that the classic Fisher (1930)...

While CBOE's VIX index is widely acknowledged as a broad-based investor “fear gauge” for its strong inverse relationship with major equity indexes, one cannot necessarily expect it to translate to the level of future turbulence or investor risk aversion in fixed-income markets. Indeed,...

The paper investigates the relationship between the investment holding horizon and liquidity. I confirm and expand earlier findings on this issue: less liquid stocks are held by long term investors. Further, I find that stocks held for a short period carry more of liquidity risk. This means that...

A small investor provides liquidity at the best bid and ask prices of a limit order market. For small spreads and frequent orders of other market participants, we explicitly determine the investor's optimal policy and welfare. In doing so, we allow for general dynamics of the mid price, the...

This paper studies equilibrium in a pure exchange economy with unobservable Markov switching consumption growth regimes and regime-dependent preferences. Variations in risk attitudes have fundamental effects on the structure of equilibrium. Explicit solutions are provided for the market price of...

In this paper, we propose an easy-to-use yet comprehensive model for a system of cointegrated commodity prices. While retaining the exponential affine structure of previous approaches, our model allows for an arbitrary number of cointegration relationships. We show that the cointegration...
