Since Black (1976), the source of the stock price volatility smirk has remained a controversy. The volatility smirk is … volatility smirk, both for time series and cross sections of companies. These results may help to disentangle the leverage effect … from other potential explanations like volatility feedback, the time-varying risk premium, and a down-market effect. …

In this paper we derive a market value for Guaranteed Annuity Optionusing martingale modeling techniques. Furthermore, we show how to construct a static replicating portfolio of vanillainterest rate swaptions that replicates the Guaranteed Annuity Option. Finally, we illustrate with historical...

Electricity is not storable. As a consequence, electricity demand and supply need to be in balance at any moment in time as a shortage in production volume cannot be compensated with supply from inventories. However, if the installed power supply capacity is very flexible, variation in demand...

We present a new framework for the joint estimation of the default-free government term structure and corporate credit spread curves. By using a data set of liquid, German mark denominated bonds, we show that this yields more realistic spreads than traditionally obtained spread curves that...

In this paper, we introduce two classes of indices which can be used to measure the market perception concerning the degree of dependency that exists between a set of random variables, representing di¤erent stock prices at a …xed future date. The construction of these measures is based on the...
