High‐commitment HR practices,employee effort,and firm performance: Investigating the effects of HR practices across employee groups within professional services firms

In this study, the authors examine the relationship between high‐commitment HR practices and firm performance in professional services firms through the mediator of employee effort. In addition, they contribute to the debate in the field of strategic HRM on whether high‐commitment HR practices should be used across all employee groups within a firm. Their study's results show that high‐commitment HR practices positively relate to firm performance through employee effort for two employee groups within professional services firms. Further, they found that the relationship between effort and performance is contingent on the value of the employee group to firm competitive advantage, suggesting that companies may only want to expend the effort and resources on building a high‐commitment HR system for employee groups that are clearly tied to creating firm competitive advantage. © 2011 Wiley Periodicals, Inc.

The proposed elimination of full cost accounting in the extractive petroleum industry: An empirical assessment of the market consequences

On July 15, 1977, the Financial Accounting Standards Board (FASB) issued an Exposure Draft of Statement 19 in which a proposal was set forth to establish the uniform usage of successful efforts accounting and to eliminate full cost accounting in the extractive petroleum industry. This study addresses the question of whether the proposed elimination of full cost accounting had an adverse effect on the security returns of full cost versus successful efforts firms. The evidence presented in this study suggests that the proposal to eliminate full cost accounting was associated with a significant negative difference in risk-adjusted rates between full cost firms and successful efforts firms whose financial reports remained unaffected by the proposed change. This observed difference was found to be sustained over an eight month period including confirming events and disclosures associated with the initial proposal. We do not attribute this difference to market inefficiencies but, rather, to the anticipated consequences which this mandated accounting change is likely to have on managerial behavior and to increased costs that will have to be borne by the affected companies.     

An Experimental Investigation of Moral Hazard in Costly Investments

Frequently, parties make sequential decisions regarding investments for which the probability of success or failure is dependent on the amount of total investment. This paper reports a series of experiments involving a costly investment game that is derived from the catalytic finance model of Morris and Shin (Global games: Theory and applications. In Advances in Economics and Econometrics, Proceedings of the Eighth World Congress of the Econometric Society, edited by M. Dewatripont, L. Hansen, and S. Turnovsky. Cambridge, MA: Cambridge University Press, pp. 56-114). The sequential nature of investments is such that the second investment could function as a complement to the initial investment or simply serve as a substitute to it, thereby creating moral hazard. The features of this game are similar to those of the ultimatum game. However, there are several key differences between the games that may account for the high frequency of materially self-interested behavior that we observe, particularly among second movers.     

Supply response of farm program in rice-growing states

This study aims to develop an acreage response model for rice-growing states using a policy-inducing variable. The single equation regression model for each rice-producing state is estimated by using the ordinary least square multiple regression procedure after log transformation. Data for the period 1959 to 1988 for acreage plantation, market price, target price, loan rate, and acreage reduction rate are used in designing the policy-inducing price. The estimated parameter shows a significant inverse relationship between the rice acreage planted and policy-inducing prices in all of the rice-growing states, with the exception of Louisiana. The estimated short-run elasticities for Arkansas, California, Louisiana, Mississippi, and Texas are -0.36, -0.68, 0.30, -0.37, and -0.59, respectively. The heterogeneity in the magnitude of the elasticities suggests the need for redesigning the rice programs to generate desirable acreage responses from all of the rice-growing states.     

Sexual harassment . . . some see it . . . some won't

Is sexual harassment a serious issue for managers, and does it occur as much in business as the popular press would have us believe? How difficult will it be to implement the newly issued EEOC guidelines? Out of a joint survey with Redbook magazine, HBR takes a look at these and other questions. Eliza Collins and Timothy Blodgett explore definitions of harassment, analyze respondents' replies, and suggest ways to counter the problem.     

Disaggregate spatio-temporal assessments of population exposure to aircraft noise

Estimates of exposure to aircraft noise are generally based on an average day of operations and residential population figures. While providing a convenient way to condense information, this does not reflect noise experiences across the day. This paper details an approach to inject more reality into exposure assessments, using disaggregate geographic information systems-based flight movement data and a procedure to track the population over the day. Using empirical evidence from Sydney, this leads to markedly different insights about noise impacts, which in turn has ramifications for policy-makers planning flight operations and residential settlement patterns in impacted areas.     

The risk management effectiveness of multivariate hedging models in the U.S. soy complex

Several authors have proposed sophisticated multivariate hedging strategies which use portfolio theory and complex econometric techniques. Practical application of these techniques requires using historical data to make decisions about future hedging portfolios. This paper tests to see if there is enough stationarity in the data for these models to actually provide better hedging strategies in practice. For the soy complex the results are clear. No statistically significant improvement over naive equal and opposite hedges was found for any of the multivariate hedging models. So far, there is no known evidence that any of these methods perform reliably in practice. © 2000 John Wiley & Sons, Inc. Jrl Fut Mark 20:189–204, 2000     

Environment versus industry: A case study of how the pulp and paper industry is responding to changing attitudes to the environment

‘Environment Friendly’ has become one of the most popular catchphrases of the 1990s and its implications are causing problems for many industries (The Economist, 1991a). The problems and response strategies vary from industry to industry and probably from country to country. In this study attention is focused on the pulp and paper sector in Europe. Pulp and paper is selected because for a long time it has been regarded as one of the most damaging industrial activities (Zavatta, 1988). The increasingly popular desire for a greener environment has exposed three particular problem areas for the pulp and paper industry: the production process; its supply of raw materials; and marketing strategy (Brown, 1991). Technology and consumer demand are the important variables that are dictating how fast, and to what extent the pulp and paper industry can respond and become more environment friendly. Pressures on the pulp and paper industry to improve its environmental performance are shown to emanate from three distinct groups. These environmental pressures have encouraged and are encouraging the industry to adopt new technology to improve both its production processes and the quality of its product. Environmental pressures also, have encouraged the industry, (armed with improved technology), to search for new sources of raw materials. Two of the most important developments have been the more widespread substitution of hardwoods for traditional coniferous softwoods, and the increasing trend towards the recycling of waste paper; wastepaper is now recycled more than any other commodity. Recycling of waste paper has further promoted new layers of industrial activity in the form of collection agencies, international trade and deinking installations. The combined result of all these developments is shown to influence the spatial and structural dynamics of the pulp and paper-industry in Europe.     

PRICE AND VOLUME EFFECTS ASSOCIATED WITH THE CREATION OF STANDARD & POOR'S MIDCAP INDEX

In this paper we explore price and volume effects associated with the 1991 creation of Standard & Poor's MidCap 400 index. Prior work on changes in the composition of existing indices finds a significant price response to the announcement. Various authors link the effect to price pressure, information, an outwardly shifting demand curve for securities, and the increased attention that comes with inclusion in an index. Using event study methodology, we find significant price and volume effects during the two weeks leading up to the Standard & Poor's announcement, but no significant effect in the two-day interval around the event. Apparently, information leakage and/or anticipation preceded the creation of the index. The price run-up is permanent since the positive abnormal returns leading up through the announcement are not associated with significantly negative abnormal returns after the announcement. In addition, MidCap stocks significantly outperform the market during the fifty-two weeks following the announcement. Using cross-sectional regressions, we show that these prior-period abnormal returns are positively related to abnormal volume and institutional holdings. We also find that firms trading over-the-counter had larger price run-ups than NYSE or AMEX firms.
