Imperfect predictability and mutual fund dynamics. How managers use predictors in changing systematic risk.
Amisano, Gianni; Savona, Roberto - 2008
Suppose a fund manager uses predictors in changing port-folio allocations over time. How does predictability translate into portfolio decisions? To answer this question we derive a new model within the Bayesian framework, where managers are assumed to modulate the systematic risk in part by...

Cash Flow and Discount Rate Risk in Up and Down Markets: What is actually priced?
Botshekan, Mahmoud; Kraeussl, Roman; Lucas, Andre - 2010
We test whether asymmetric preferences for losses versus gains as in Ang, Chen, and Xing (2006) also affect the pricing of cash flow versus discount rate news as in Campbell and Vuolteenaho (2004). We construct a new four-fold beta decomposition, distinguishing cash flow and discount rate betas...

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 geography of international portfolio flows, international CAPM and the role of monetary policy frameworks
De Santis, Roberto A. - 2006
Using bilateral data on international equity and bond flows, we find that the prediction of the International Capital Asset Pricing Model is partially met and that global equity markets might be more integrated than global bond markets. Moreover, over the turbulent 1998-2001 period characterised...

Risk-value efficient portfolios and asset pricing
Franke, Günter; Weber, Martin - 1997
Portfolio choice is usually modelled by von Neumann-Morgenstern utility. Risk-value models are more general and permit the derivation of risk-value efficient frontiers. A behaviorally based risk measure with an endogenous or exogenous benchmark is used to derive efficient portfolios and to...

Discrete and continuous time dynamic mean-variance analysis
Reiss, Ariane - 1999
Contrary to static mean-variance analysis, very few papers have dealt with dynamic mean-variance analysis. Here, the mean-variance efficient self-financing portfolio strategy is derived for n risky assets in discrete and continuous time. In the discrete setting, the resulting portfolio is...

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 …
