Conditionally parametric fits for CAPM betas
Abberger, Klaus - 2004
The CAPM model assumes stock returns to be a linear function of the market return. However, there is considerable …

One-factor-Garch models for German stocks: Estimation and forecasting
Kaiser, Thomas - 1996
This paper presents theoretical models and their empirical results for the return and variance dynamics of German stocks. A factor structure is used in order to allow for a parsimonious modeling of the first two moments of returns. Dynamic factor models with GARCH dynamics (GARCH(1,1)-M,...

The stable long-run CAPM and the cross-section of expected returns
Kim, Jeong-Ryeol - 2002
The capital-asset-pricing model (CAPM) is one of the most popular methods of financial market analysis. But, evidence … of the poor empirical performance of the CAPM has accumulated in the literature. For example, based on their empirical … results regarding the relation between market Beta and average return, Fama and French (1996) conclude that the CAPM is no …

Mean-Variance Efficiency and Intertemporal Price for Risk
Leitner, Johannes - 2000
In a continuous time, arbitrage free, non-complete market with a zero bond, we find the intertemporal price for risk to equal the standard deviation of the discounted variance opti- mal martingale measure divided by the zero bond price. We show the Hedging Numeraire to equal the Market Portfolio...

The Stochastic Volatility in Mean Model
Koopman, Siem Jan; Uspensky, Eugenie Hol - 2000
In this paper we present an exact maximum likelihood treatment forthe estimation of a Stochastic Volatility in Mean(SVM) model based on Monte Carlo simulation methods. The SVM modelincorporates the unobserved volatility as anexplanatory variable in the mean equation. The same extension...

Time-Varying Market Integration and Expected Returns in Emerging Markets
de Jong, Frank; de Roon, Frans A. - 2001
We use a simple model in which the expected returns in emerging markets depend on their systematicrisk as measured by their beta relative to the world portfolio as well as on the level ofintegration in that market. The level of integration is a time-varying variable that depends on themarket...
