Vorgestellt wird eine empirische Studie, welche den Zusammenhang zwischen Rendite und Risiko für ein Sample deutscher Versicherungsaktien im Zeitraum 1975-1998 untersucht. Als Methode wurde ein Multifaktorenmodell mit makroökonomischen Faktoren verwendet. Je nach Untersuchungszeitraum beläuft...

Traditional tests of the CAPM following the Fama / MacBeth (1973) procedure are tests of thejoint hypotheses that there is a relationship between beta and realized return and that the marketrisk premium is positive. The conditional test procedure developed by Pettengill / Sundaram/ Mathur (1995)...

Der mit der Frage nach der Existenz von Zeithorizonteffekten im Rahmen einer Aktienanlage verbundene Themenkomplex ist anhaltender Gegenstand einer intensiven und kontroversen Debatte sowohl innerhalb der Investmenttheorie als auch der Investmentpraxis. ...

We develop an econometric methodology to infer the path of risk premia from large unbalancedpanel of individual stock returns. We estimate the time-varying risk premia implied by conditional linearasset pricing models where the conditioning includes instruments common to all assets and asset...

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...

The 2007-2008 financial crises has made it painfully obvious that markets may quickly turn illiquid.Moreover, recent experience has shown that distress and lack of active trading can jump “around”between seemingly unconnected parts of the financial system contributing to transforming...

CAT bonds are of significant importance in the field of alternative risk transfer. Since themarket of CAT bonds is not complete, the application of an appropriate pricing model is of high relevance.We apply different premium calculation models in order to compare them with regard to...

This paper examines the question to what extent premia for macroeconomic risks inbanking are sufficient to avoid banking crises. We investigate a competitive bankingsystem embedded in an overlapping-generations model subject to repeatedmacroeconomic shocks. We show that even if banks fully...

We consider time series models in which the conditional mean of the response variable given thepast depends on latent covariates. We assume that the covariates can be estimated consistentlyand use an iterative nonparametric kernel smoothing procedure for estimating the conditional meanfunction....
