We propose several connectedness measures built from pieces of variance decompositions, and we argue that they provide natural and insightful measures of connectedness among financial asset returns and volatilities. We also show that variance decompositions define weighted, directed networks, so...

Although the equity premium is - both from a conceptual and empirical perspective - a widely researched topic in finance, there is still no consensus in the academic literature about its magnitude. In this paper, we propose a different estimation method which is based on credit valuations. The...

We consider the modelling of credit migration risk and the pricing of migration derivativesour approach enlarges the traditional setup where credit risk is based on default solely.We implement the Regime Shifting Markov Mixture model developed in Andersson (2007)and Andersson and Vanini (2008)...

This paper contributes to the ongoing discussion on price formation in electricity markets. For this, we conduct an analysis of the German electricity wholesale spot market which is located at the European Energy Exchange (EEX). Our dataset covers three spot market segments, namely the intraday...

The mechanism behind price formation in electricity futures markets is still under discussion. Theory suggests that hedging pressure caused by deviating risk preferences is the most promising approach. This paper contributes to this discussion through an empirical investigation of electricity...

I discuss a network of banks which are linked with each other by financial obligations and cross holdings. Given an initial endowment the value of the obligations and the equity values of the banks are determined endogenously in a way consistent with the priority of debt and the limited...

Credit risk models used in quantitative risk management treat credit risk analysis conceptually like a single person decision problem. From this perspective an exogenous source of risk drives the fundamental parameters of credit risk: probability of default, exposure at default and the recovery...

The purpose of this paper is to investigate if credit markets believe in the existence of a central government guarantee and if this can be observed in the yield spread of the municipal sector. This is done by decomposing the municipal bond yield spread into liquidity and credit risk premiums by...
