The empirical validity of alternative views about the short-run determinants of real output growth in the United States is investigated. A nested framework is used to test the macro rational expectations (MRE) hypothesis directly against two competing hypotheses - the neo-Keynesian view that anticipated and unanticpated monetary policy both matter,and Friedman's (1977) proposition that increased inflation uncertainty reduces real output at least temporarily. The unobservable explanatory variables are obtained from time-varying-parameter models of inflation and money growth, which generate forecast errors and their conditional variances consistent with rational expectations under a continuously chaning policy regime. The empirical results strongly support Friedman's view. The MRE hypothesis must be rejected since both anticipated and unanticipated monetary changes matter. The results prove robust across different model specifications and estimation techniques. 相似文献

Moving to scanner based and quantity-weighted monthly average retail beef price series has changed the price series significantly. Quantity-weighted price levels are lower and more volatile. Perhaps most important, calculated elasticities for the quantity-weighted averages are lower than for the historical simple average data. Elasticity estimates for simple average monthly price data are also larger than for weekly data, raising the possibility that historic demand analyses have significantly overstated own price demand elasticities. 相似文献

This study examines the economic performance of target and bidding companies where the target successfully defended a hostile takeover bid in the period 1975–1984. Returns to shareholders in both target and bidding companies are measured for the six months preceding the bid, and for the twenty-four months after the bid. The study finds that the significant gains obtained by shareholders in the target company around the time of the bid announcement are not lost after the failure of the bid. In apparent defiance of the efficient market hypothesis abnormal returns continue for the two years after the bid. As for the bidding company, the small positive abnormal returns to its shareholders are also sustained after the bid. 相似文献

Although the literature on traditional workplace bullying is advancing rapidly, currently investigations addressing workplace cyberbullying are sparse. To counter this, we present three connected research studies framed within dysempowerment theory (Kane, K., & Montgomery, K. (1998). A framework for understanding dysempowerment in organizations. Human Resource Management, 37, 263–275.) which examine the relationship between volume and intensity of cyberbullying experience and individual mental strain and job satisfaction; whether the impact is more negative as compared to traditional bullying; and whether state negative affectivity (NA) and interpersonal justice mediate the relationship. Additionally, we also considered the impact of witnessing cyberbullying acts on individual outcomes. A total sample comprised 331 UK university employees across academic, administrative, research, management and technical roles. Overall, significant relationships between cyberbullying exposure and outcomes emerged, with cyberbullying exposure displaying a stronger negative relationship with job satisfaction when compared to offline bullying. Analysis supported an indirect effect between cyberbullying acts and outcomes via NA and between cyberbullying acts and job satisfaction via interpersonal justice. No support for a serial multiple mediation model of experiencing cyberbullying to justice to NA to outcome was found. Further, perceived intensity of cyberbullying acts and witnessing cyberbullying acts did not significantly relate to negative outcomes. Theoretical and practical implications of the research are discussed. 相似文献

In corporate contests, employees compete for a prize. Ideally, contests induce employees to exert productive effort which increases their probability of winning. In many environments, however, employees can also improve their own ranking position by harming their colleagues. Such negative incentive effects of corporate contests are largely unexplored, which can partly be attributed to the fact that sabotaging behavior is almost unobservable in the field. In this study we analyze behavior in experimental contests with heterogeneous players who are able to mutually sabotage each other. We find that sabotaging behavior systematically varies with the composition of different types of contestants. Moreover, if the saboteur’s identity is revealed sabotage decreases while retaliation motives prevail. Our results promise to be valuable when designing corporate contests. 相似文献

This article analyzes the motivations, internalization challenges and outcomes of implementing certifiable standards for corporate biodiversity management. For this purpose, a qualitative study based on interviews with 39 environmental managers, auditors, consultants and other experts in the field was conducted. The findings show that the adoption of new standards for biodiversity management is essentially driven by the need to improve the social acceptability of activities that can have a significant impact on natural habitats. The possible benefits of certification, particularly in terms of stakeholder relationships, and the difficulty of measuring the intangible aspects of biodiversity issues are also discussed. The study contributes to the emerging literature on organizational biodiversity management and to the debates on the symbolic versus substantial adoption of certifiable environmental standards. Managerial implications for organizations interested in biodiversity management are also discussed. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment 相似文献
