The association between audit committees,compensation incentives,and corporate audit fees

This study uses audit fee data from the 2001–2003 reporting periods to examine the relationship between measures of audit committee effectiveness and compensation incentives with corporate audit fees. Our results suggest that audit committee size, committee member expertise, and committee member independence are positively associated to audit fee levels, consistent with the notion that audit committees serve as a complement to external auditors in monitoring management. In contrast, CEO long-term pay and insider ownership are inversely related to audit fee levels, substituting for external audit effort in motivating management. Notwithstanding results on the full sample of firm-years, we uncover significant differences in the determinants of audit fees between the years examined. An important implication of these results is that explaining the intra-firm variation in audit fees over time is clearly necessary in order to understand the antecedents and consequences of audit fees.

The forward pricing function of the shipping freight futures market

This article investigates the unbiasedness hypothesis of futures prices in the freight futures market. Being the only market whose underlying asset is a service, it sets it apart from other markets investigated so far in the literature. Cointegration techniques, employed to examine this hypothesis, indicate that futures prices one and two months before maturity are unbiased forecasts of the realized spot prices, whereas a bias exists in the three-months futures prices. This mixed evidence is in agreement with studies in other markets and suggests that the acceptance or rejection of unbiasedness depends on the idiosyncrasies of the market under investigation and on the time to maturity of the contract. Despite the existence of a bias in the three-months prices, futures prices for all maturities are found to provide forecasts of the realized spot prices that are superior to forecasts generated from error correction, ARIMA, exponential smoothing, and random walk models. Hence it appears that users of the BIFFEX market receive accurate signals from the futures prices (regarding the future course of cash prices) and can use the information generated by these prices to guide their physical market decisions. © 1999 John Wiley & Sons, Inc.

Perfect and imperfect real-time monitoring in a minimum-effort game

This paper presents the results from a minimum-effort game in which individuals can observe the choices of others in real time. We find that under perfect monitoring almost all groups coordinate at the payoff-dominant equilibrium. However, when individuals can only observe the actions of their immediate neighbors in a circle network, monitoring improves neither coordination nor efficiency relative to a baseline treatment without real-time monitoring. We argue that the inefficacy of imperfect monitoring is due to information uncertainty, that is, uncertainty about the correct interpretation of a neighbor’s actions. Information uncertainty prevents individuals from inferring safely that their group has managed to coordinate from the available information.     

A novel risk management framework for natural gas markets

This paper examines dynamic hedges in the natural gas futures markets for different horizons and explores the gains from devising risk management strategies. Despite the substantial progress made in developing hedging models, forecast combinations have not been explored. We fill this gap by proposing a framework for combining hedge-ratio predictions. Composite hedge ratios lead to significant reduction in portfolio risk, whether spot prices are partially predictable or not. We offer insights on hedging effectiveness across seasons, backwardation-contango conditions and the asymmetric profiles of long-short hedgers. We conclude that forecast combinations better reconcile realized performance with the hedging process, mitigating model instability.     

Mentoring receipt and personality: Evidence for non-linear relationships

The research investigates the relationship of the Big-Five of personality with mentoring receipt with the use of two independent studies. The findings of the studies show substantial consistency. Equations of quadratic form describe half of the tested relationships better than linear equations. The association of openness to experience and agreeableness with mentoring receipt is of inverted U-shape. The benefits of being open and agreeable for mentoring receipt cease to exist at high values of these traits. On the other hand, emotional stability and conscientiousness demonstrate exclusively positive linear relationships with mentoring receipt. The form of the relationship of extraversion differs between the two studies, but the overall trend is positive. The substantial quadratic component in the association of personality with receipt of mentoring means that research hitherto may be grossly underestimating the effects of personality on developmental relationships because earlier studies assume strictly linear associations. Parts of the results also imply that the associations of certain personality traits with mentoring receipt may depend upon the occupational context.     

A Markov regime switching approach for hedging energy commodities

This paper estimates constant and dynamic hedge ratios in the New York Mercantile Exchange oil futures markets and examines their hedging performance. We also introduce a Markov regime switching vector error correction model with GARCH error structure. This specification links the concept of disequilibrium with that of uncertainty (as measured by the conditional second moments) across high and low volatility regimes. Overall, in and out-of-sample tests indicate that state dependent hedge ratios are able to provide significant reduction in portfolio risk.     

Earnings Management Around Share Repurchases: A Note

This work examines a subset of the important area of earnings management. Specifically, it seeks to identify the extent of earnings management preceding self-tender offers for a sample of U.S. firms. Pre-repurchase total accruals and discretionary current accruals were found to be somewhat lower for a sample of self-tendering firms compared to a sample of industry- and performance-matched control firms. Weak evidence of post-buyback accruals reversal is also presented. The evidence is weakly consistent with the notion that share repurchases are employed by managers to exploit shareholders through earnings management.     

Third-party punishment and counter-punishment in one-shot interactions

This paper presents experimental evidence from a simple three-person game showing that many individuals are willing to avenge third-party punishment in one-shot interactions. The threat of counter-punishment has a large negative effect on the willingness of third parties to punish selfish behavior. In spite of this, the extent of selfish behavior is identical to that in a treatment without counter-punishment opportunities. We discuss explanations for this puzzling finding.     

Innovation diffusion: The emerging role of suppliers versus the traditional dominance of buyers

This paper evaluates and extends some of the recent ideas of Robertson and Gatignon regarding the importance of supply‐side factors in the organizational diffusion of innovations. We develop arguments for the premise that diffusion theory should not only take buyer characteristics and behaviour into account but should also view the suppliers’ new product development and marketing activities as pro‐active variables.

A typology of supply‐side factors is presented based on empirical evidence from salient fields of inquiry which cover sociology, industrial economics, new product development, marketing and industrial buyer behaviour. From this, we present some issues for further research in the form of eight key propositions.
