Overburden deformation associated with halokinesis in the Southern North Sea: implications for the origin of the Silverpit Crater

Gravitational collapse in response to the creation of salt swells and diapirs is a common phenomenon within regions such as the Southern North Sea. Although collapse faulting and slumping of linear salt swell flanks has previously been documented, the existence of concentric collapse structures surrounding diapirs and isolated salt lows is a recently recognised feature. 3-D seismic data from the Southern North Sea demonstrates that concentric collapse faulting around both diapirs and subcircular salt lows is common. The recognition of concentric collapse structures formed in response to salt withdrawal, and adjacent inflation, provides an alternative mechanism for the origin of the proposed Silverpit impact crater.     

A Backward Induction Experiment

This paper reports experiments with one-stage and two-stage alternating-offers bargaining games. Payoff-interdependent preferences have been suggested as an explanation for experimental results that are commonly inconsistent with players' maximizing their monetary payoffs and performing backward induction calculations. We examine whether, given payoff-interdependent preferences, players respect backward induction. To do this, we break backward induction into its components, subgame consistency and truncation consistency. We examine each by comparing the outcomes of two-stage bargaining games with one-stage games with varying rejection payoffs. We find and characterize systematic violations of both subgame and truncation consistency. Journal of Economic Literature Classification Numbers: C70, C78.     

Retirements at risk: employees lack a comprehensive, realistic view of resources and needs

Employees who are following conventional retirement-planning advice will be in for a rude awakening as they approach retirement and discover that they can't afford to retire just yet or are likely to outlive their retirement funds. The article discusses how we have arrived at this point, what the implications are, and what both employers and employees can do to remedy the situation.     

Wall Street''s contribution to management accounting: the Stern Stewart EVAfinancial management system

EVA^®is a variant of residual income marketed byStern Stewart & Co., a New York consulting firm, with the purpose of promoting value–maximizing behaviour in corporate managers. This paper reviews the EVA system in the light of this purpose. First, it outlines the rationale for the use of residual income in ‘value-based management’, highlighting the potential shortcomings of residual income as a single-period performance indicator. Second, it considers the adjustments to GAAP-based accounting advocated by Stern Stewart in order to produce a more economically meaningful version of residual income (EVA) which might serve as an effective indicator of single-period performance. Third, it examines the Stern Stewart approach to the setting of EVA benchmarks. Finally, it reviews the logic behind the use of the ‘bonus bank’ to separate the award of EVA–based bonuses from the payment of such bonuses.     

Effects of Feedback and Task Predictability onTask Learning and Judgment Accuracy

This study examines the effect of different types of feedback on task learning and judgment accuracy across different levels of task predictability. The results of a laboratory study show that outcome feedback, alone, and in combination with task properties feedback, promotes judgment accuracy for both high and medium levels of task predictability. The beneficial impact of outcome feedback resulted from learning effects. Specifically , the outcome feedback improved judgment accuracy because of improved task knowledge and, in contrast to previous psychology research, it did not cause a deterioration in judgment consistency where task predictability was less than perfect. The results suggest that the negative effects of outcome feedback on judgment accuracy found in the psychology literature, where task predictability is less than perfect, may be limited in accounting settings where judges have experience with the task.     

INFORMATION ASYMMETRY,MANAGEMENT CONTROL,AND METHOD OF PAYMENT IN ACQUISITIONS

We examine the information asymmetry hypothesis and the management control hypothesis by examining the relation between insider trading and insider holdings to the choice of payment method in acquisitions. Our results indicate that both insider ownership and insider trading are significantly related to payment method. These results provide additional evidence for both the management control theory and the asymmetric information theory in the choice of payment method in acquisitions. Furthermore, we find a significant relation between insider trading activity and the market reaction to the announcement of acquisitions. We conclude that information asymmetry exists in the takeover market and that it influences the payment method decision.
