The increasing importance of renewable energy, especially solar and wind power, has led to new forces in the formation of electricity prices. Hence, this paper introduces an econometric model for the hourly time series of electricity prices of the European Power Exchange (EPEX) which...

Siegel (1995) has developed a technique with which the systematic risk of a security (beta) can be estimated without recourse to historical capital market data. Instead, beta is estimated implicitly from the current market prices of exchange options that enable the exchange of a security against...

This paper extends the option pricing equations of Black and Scholes [1973. Journal of Political Economy 81, 637–654], Jarrow and Madan [1997. European Finance Review 1, 15–30] and Husmann and Stephan [2007. Journal of Futures Markets 27, 961–979]. In particular, we show that the length of...

Measurement in financial accounting often requires determining an interest rate to discount future cash flows. One example is the International Accounting Standard (IAS)36 Impairment of assets. IAS 36´s impairment test requires determining a value in use (a present value). The Appendix A to the...
