We consider the finite sample properties of model selection by information criteria in conditionally heteroscedastic models. Recent theoretical results show that certain popular criteria are consistent in that they will select the true model asymptotically with probability 1. To examine the...

Panel research assessment and the use of metrics in evaluating the quality of academics and the institutions in which they work has become an increasingly ubiquitous activity. The assessment of new knowledge derived via research is controversial, and how that evaluation occurs may have important...

This study is situated in an investment context and explores how the effect of framing (gain versus loss framing) changes the impact of incidental emotions (fear and excitement) on behavioral and physiological outcome measures. While existing literature has found that the effects of framing and...

This study assesses whether the widely documented momentum profits can be attributed to time-varying risk as described by a GJR-GARCH(1,1)-M model. We reveal that momentum profits are a compensation for time-varying unsystematic risks, which are common to the winner and loser stocks but affect...

We employ a large dataset of physical inventory data on 21 different commodities for the period 1993-2011 to empirically analyze the behaviour of commodity prices and their volatility as predicted by the theory of storage. We examine two main issues. First, we analyze the relationship between...

This study assesses whether the widely documented momentum profits can be ascribed to time-varying risk as described by a GJR-GARCH(1,1)-M model. Consistent with rational pricing in efficient markets, we reveal that momentum profits are a compensation for time-varying unsystematic risks, common...

This article proposes a new model for autoregressive conditional heteroscedasticity and kurtosis. Via a time-varying degrees of freedom parameter, the conditional variance and conditional kurtosis are permitted to evolve separately. The model uses only the standard Student`s t-density and...

This paper compares a number of different extreme value models for determining the value at risk of three LIFFE futures contracts. A semi-nonparametric approach is also proposed where the tail events are modeled using the Generalised Pareto Distribution and normal market conditions are captured...
