PRICING OPTIONS ON VARIANCE IN AFFINE STOCHASTIC VOLATILITY MODELS

We consider the pricing of options written on the quadratic variation of a given stock price process. Using the Laplace transform approach, we determine semi‐explicit formulas in general affine models allowing for jumps, stochastic volatility, and the leverage effect. Moreover, we show that the joint dynamics of the underlying stock and a corresponding variance swap again are of affine form. Finally, we present a numerical example for the Barndorff‐Nielsen and Shephard model with leverage. In particular, we study the effect of approximating the quadratic variation with its predictable compensator.     

A note on utility‐based futures hedging performance measure

This note considers the estimator for the utility‐based hedging performance. It shows that the estimator incurs a downward bias, regardless of whether the conventional mean‐variance expected utility function or the more general risk‐averse utility function is adopted. Consequently, the usefulness of the futures contract is under‐estimated. © 2011 Wiley Periodicals, Inc. Jrl Fut Mark     

Consumer evaluations of brand extension: The roles of case‐based reminding on brand‐to‐brand similarity

Utilizing the case‐based reminding theory in analogical reasoning, this research proposes that the evaluation of a brand extension can be improved by reminding consumers of a similar brand in the extension category. This effect is derived from a brand‐to‐brand similarity, in addition to the product‐to‐product and brand‐to‐product similarity identified in prior literature. Experiment 1 explores the idea that the effect of similar case reminders is most pronounced in moderately similar extensions than in highly similar or highly dissimilar extensions due to schema congruity. Experiments 2 and 3 distinguish the levels of similarity (i.e., product‐to‐product, brand‐to‐product, and brand‐to‐brand similarity) as a source of consumers' evaluations on a brand extension and further eliminate an alternative explanation of instantaneous learning in the advertisement setup of Experiment 1. © 2010 Wiley Periodicals, Inc.     

Price Discovery in Interrelated Markets

In this study, we generalize the information share (IS) proposed by Hasbrouck (1995) and extended by Lien and Shrestha (2009). The new generalized information share (GIS) can be used to analyze the price discovery process in interrelated securities markets, whereas the previous two measures can only be applied to almost identical markets. Thus, using the GIS, we can analyze broader markets thereby improving our understanding of the price discovery process as well as the efficiency of securities markets. As an empirical demonstration of the proposed method, we apply the GIS to credit default swap (CDS) and bond markets, and find that for the majority of cases price discovery mostly takes place in the CDS markets. © 2012 Wiley Periodicals, Inc.

The adoption,character and impact of strategic human resource management: a case study of two large metropolitan Vietnamese public hospitals

In this paper the researchers set out to explore the adoption, character and impact of strategic human resource management (SHRM) in two large metropolitan Vietnamese public hospitals using a multi-level qualitative research design. Data are analyzed from 21 interviews and 5 focus groups with key players from the hospitals and government authorities. Findings show that the State controls many of the core day-to-day HR functions of public hospitals, curtailing local autonomy and management innovation. This is compacted by inadequate government funding, poor training of medical staff, and inadequate management and business skills of hospital managers. Inhibiting greater experimentation with SHRM is the fear of developing management initiatives out of sync with the State. Consequently, many managers and clinicians held negative views of the HR department and their relevance for the day-to-day management of healthcare services. Respondents reported that they perceived these factors had a negative impact on the well-being of medical staff and the quality of patient care. The paper concludes with a discussion on the necessity for continued State reforms that can enable greater autonomy of the hospitals' HRM functions and greater investment in local HR capabilities to materialize the link between SHRM, employee well-being and quality of patient care.     

Delivery risk and the hedging role of options

Multiple delivery specifications exist on nearly all commodity futures contracts. Sellers typically are allowed to deliver any of several grades of the underlying commodity and at any of several locations. On the delivery day, the futures price as such needs not converge to the spot price of the par‐delivery grade at the par‐delivery location, thereby imposing an additional delivery risk on hedgers. This article derives the optimal hedging strategy for a risk‐averse hedger in the presence of delivery risk. In particular, it is shown that the hedger optimally uses options on futures for hedging purposes. This article provides a rationale for the hedging role of options when futures markets allow for multiple delivery specifications. © 2002 Wiley Periodicals, Inc. Jrl Fut Mark 22:339–354, 2002     

Non-parametric estimation of decision makers' risk aversion

A new non‐parametric method to estimate a decision maker's coefficient of absolute risk aversion from observed economic behaviour is explained. The method uses the expected value‐variance (E‐V) framework and quadratic programming. An empirical illustration is given using Norwegian farm‐level data.     

The effects of incentive types and appeal regulatory framing in travel advertising

What types of incentives and regulatory-framed advertising appeals are preferable when the promoted travel destination in a travel advert is spatially distant vs. near? Based on construal-level theory, this paper addresses this question by investigating whether there is a matching effect between the spatial distance of the travel destination and the incentives or the regulatory-framed appeals in ads. The experimental results indicate that when the promoted travel destination is spatially distant, consumers prefer non-monetary incentives and promotion-framed appeals. When the travel destination is spatially near, however, monetary incentives and prevention-framed appeals can generate better advertising effectiveness.     

Moments of truncated bivariate log-normal distributions

In this paper, we derive the expressions for the moments of truncated bivariate log-normal distributions. The results are then applied to test the Houthakker effect in futures markets.
