We explore hedging in web forum conversations, which is interestingly different to hedging in academic articles, the main focus of recent automatic approaches to hedge detection. One of our main results is that forum posts using hedges are more likely to get high ratings of their usefulness. We also make a case for focusing annotation efforts on hedges that take the form of first-person epistem...

Risk aversion is a key element of utility maximizing hedge strategies; however, it has typically been assigned an arbitrary value in the literature. This paper instead applies a GARCH-in-Mean (GARCH-M) model to estimate a time-varying measure of risk aversion that is based on the observed risk preferences of energy hedging market participants. The resulting estimates are applied to derive expli...

Long-term health insurance provides consumers with protection against persistent, negative health shocks. While the stochastic rise in medical spending growth may make some health risks harder to insure, financial assets could act as a hedge for medical spending growth risk. The purpose of this research was to determine whether such hedges exist. The results of this study were two-fold. First, ...

We investigate calibrating financial models using a rigorous Bayesian framework. Non-parametric approaches in particular are studied and the local volatility model is used throughout as an example. By incorporating potential calibration error into our method we design optimal hedges that minimise expected loss statistics based on different Bayesian loss functions decided by an investor’s prefer...

PURPOSE To evaluate the methodological quality and level of evidence of publications in four leading general clinical ophthalmology journals. METHODS All 1919 articles published in the American Journal of Ophthalmology, Archives of Ophthalmology, British Journal of Ophthalmology, and Ophthalmology in 2004 were reviewed. The methodological rigor and the level of evidence in the articles were r...

Objective Cognitive aging is commonly associated with a decrease in executive functioning (EF). A specific component of EF, semantic inhibition, is addressed in the present study, which presents a meta-analytic review of the literature that has evaluated the performance on the Hayling Sentence Completion test in young and older groups of individuals in order to assess the magnitude of the age e...

There has been little evidence to support the use of commodity-currency cross-hedges (Demaskey and Pearce, 1998; Benet, 1990; Eaker and Grant, 1987). However, this paper shows that if currencies can be defined as commodity currencies, as per Chen and Rogoff (2003) and Cashin, spedes and Sahay (2002), commoditycurrency cross-hedges are effective and beneficial. Two commodity currencies, the Papu...
