Erlöspotential im Schweizer Tertiärregelmarkt |

The analysis attempts to estimate the revenue potential from the provision of tertiary reserve capacity in the Swiss electricity control area based on publicly available data on historic tenders (June 2010–December 2013). A series of bidding strategies is defined for this purpose and backtested over the available time frame. We compare deterministic strategies derived from the observed price distribution of the previous day or week on the one hand with a model-based strategy on the other hand. The latter is implemented as a random forest regression model that takes into account, amongst other factors, the fill level of reservoir lakes in Switzerland.

mathematics and music |

Mathematics and music play very different roles in society. However, they are more closely related to each other than they are commonly perceived to be. This paper identifies such links in three different areas and concludes with the insight that music often has some mathematical characteristics and, more importantly, that artistic aspects can be found in mathematics as well.

hedonic elementary price indices |

My PhD thesis sheds some light on the theoretical foundations of hedonic elementary price indices. While being seen as the most promising method for quality-adjusting price indices, the hedonic approach bases upon econometric concepts that used to lack a solid formal description. The thesis tries to fill these gaps and examines hedonic elementary price indices from an axiomatic viewpoint. An application to the market of used cars in Switzerland shows and compares the empirical nature of alternative index estimators.
