In the paper the exponential risk measure of Damant and Satchell is used to formulate an investor's utility function and the properties of this function are investigated. The utility function is calibrated for a typical UK investor who would hold different proportions of equity. It is found...

This article investigates the modelling of style returns in the United States and the returns to style 'tilts' based on forecasts of enhanced future style returns. We use hidden Markov model to build our forecasts for data from 1975 to 1998. We do not include more recent observations as the...

This study introduces GARCH models with cross-sectional market volatility, which are called GARCHX models. The cross-sectional market volatility is a special case of common heteroscedasticity in asset specific returns, which is suggested by Connor and Linton (2001) as an important component in...

It is shown that the ML estimates of the popular GARCH(1,1) model are significantly negatively biased in small samples and that in many cases converged estimates are not possible with Bollerslev's non-negativity conditions. Results also indicate that a high level of persistence in GARCH(1,1)...

In this study, we propose a method based on large deviation theory (LDT), which minimises credit risk (expected loss). We demonstrate how mortgage loan portfolios can be optimised using geographical differences in the risk characteristics of mortgage loans in the UK. Our empirical results show...

In this paper, we propose the average <italic>F</italic>-statistic for testing linear asset pricing models. The average pricing error, captured in the statistic, is of more interest than the <italic>ex post</italic> maximum pricing error of the multivariate <italic>F</italic>-statistic that is associated with extreme long and short positions and...

type="main" <p>We investigate the dynamics of appraisal smoothing in the National Council of Real Estate Investment Fiduciaries (NCREIF) index return using time-varying asset pricing models. We find that smoothing is on average close to zero but varies substantially over time. From the inception of...</p>

We propose a new approach to detecting and measuring herding which is based on the cross-sectional dispersion of the factor sensitivity of assets within a given market. This method enables us to evaluate if there is herding towards particular sectors or styles in the market including the market...

Thus paper reports on an investigation into what is an appropriate level of investment management fees. Existing results are extended and several formulae are provided for the case of power utility and normal returns. Using the CRRA utility function with the range of the coefficient of the CRRA...

By carefully choosing a data-generating process and appropriate distributional assumptions, we formulate a nested econometric model to examine how many equities are explained well by the downside beta or a general asymmetric response model rather than the conventional capital asset pricing model...
