Across manufacturing sectors, mounting regulatory pressures motivate the adoption of innovative sustainable practices to help address and improve environmental performance. Sustainable practices, however, face many challenges to minimize negative environmental impacts while conserving energy and natural resources. This study seeks to understand the effect of research and development intensity on dimensions of environmental performance in manufacturing firms. Using data from U.S. corporations over the period from 1991 through 2015, we find that sustainable practices are associated with a higher level of negative environmental ratings. In addition, the level of environmental concerns tends to decrease with firm investments in research and development intensity over time. These findings suggest that bigger firms are likely to report a higher level of environmental concerns due to their experimentation with sustainable practices. These firms are also likely to reduce negative environmental ratings over time and realize economies of scale with sustainable manufacturing. 相似文献

Abstract An empirical study of a sample of 38 U.S. dominant product firms operating in manufacturing industries was undertaken to trace the patterns of internationalization of R&D and operations. First, the results of our analysis revealed that internationalization of R&D and operations were a significant part of the evolving internationalization strategies of the dominant product firms we studied. Second, while internationalization of operations was influenced by international configuration via global standardization, the internationalization of R&D was influenced by international configuration via national responsiveness and by competitive positioning via differentiation. Third, the results highlight the fact that the internationalization moves of dominant product firms are not all similar, but depend on the international configuration and competitive positioning pursued by the firms. 相似文献

This paper examines the impacts of economic policy uncertainty and oil price shocks on stock returns of U.S. airlines using both industry and firm-level data. Our empirical approach considers a structural vector-autoregressive model with variables recognized to be important for airline returns including jet fuel price volatility. Empirical results confirm that oil price increase, economic uncertainty and jet fuel price volatility have significantly adverse effect on real stock returns of airlines both at industry and at firm level. In addition, we also find that hedging future fuel purchase has statistically positive impact on the smaller airlines. Our results suggest policy implications for practitioners, managers of airline industry and commodity investors. 相似文献

Employees are increasingly given control over how they learn, and their choices for training are diverse and varied, yet employees must balance competing demands. On one hand, they are expected to be increasingly efficient in their current job duties – on the other hand, they are expected to develop new skills and competencies that enable them to adapt and respond to changing job demands. Drawing from the organizational learning literature, we propose a model of worker and work characteristics that inform choices between two mindsets related to learning at work. The first mindset is exploration, or the pursuit of learning outside one’s current knowledge domain; the second mindset is exploitation, the refinement/deepening of one’s existing knowledge stock focusing on the task at hand. We further propose that these strategic choices, or trade-offs, influence employee learning and performance in unique ways, with different implications for both routine and adaptive performance. Finally, we incorporate the notions of feedback loops and risk assessments that influence ongoing decisions between exploration and exploitation mindsets. Recommendations for future research and extensions of the theoretical model are also proposed. 相似文献

In this paper we attempt to disentangle the effects of deregulation on rail costs from those directly attributable to mergers. We estimate that cost reductions obtained from mergers ranged from a high of 33% for the Burlington Northern to a low of a 3% cost increase for the CSX. However, firms not engaged in significant merger activities experienced similar cost differentials indicating that consolidation was not a prerequisite for cost savings. We conclude that although mergers did confer some benefits on the participating firms, they were not a prerequisite for railroads being able to achieve substantial cost savings. 相似文献

The purpose of this paper is to investigate the relationship between oil price movements and equity returns of railways and airline in Canada and the U.S. Using a robust set of oil measures, which includes both West Texas Intermediate (WTI) and Western Canadian Select (WCS) data, this research finds that railways and airlines react uniquely to oil price movements. Specifically, equity returns of railways in Canada and airlines in the U.S. tend to be negatively impacted by positive movements in WTI. Equity returns of airlines in Canada and railways in the U.S show limited evidence of any impact. Additional estimations suggest that equity returns of airlines react asymmetrically and that information regarding oil price movements may gradually diffuse over time. With the changing North American energy landscape (e.g., oil sands and shale oil), the increased reliance on transporting crude oil via railways should lead academics and practitioners to further research in this area. 相似文献

We examine the tail risk spillovers between Canada and U.S. stock markets using over a century data, and also account for the roles of tail risks of other advanced economies (France, Germany, Japan, Italy, Switzerland, and the UK) and oil-market tail risk. We use the “best” tail risk measure obtained from different variants of the Conditional Autoregressive Value at Risk (CAViaR) model developed by Engle and Manganelli (2004) in the predictive model and compare its performance with that of an AR(1) benchmark model. We find strong evidence of risk spillovers between the two stock markets. We find contrasting evidence for the predictability of oil-market tail risk, with positive predictability in case of the net oil exporter and negative in case of the net oil importer. Further results using tail risks of other advanced economies (combined) support possible diversification potential for Canadian stocks in the presence of market risks of advanced economies other than the U.S. Our findings have implications for investors and are robust to various out-of-sample forecast horizons, alternative data frequencies, data splits, and 1% and 5% VaRs. 相似文献

Given the increasingly strategic role of external resources, acquiring knowledge about current suppliers and the broader supply market is an important and demanding task for the purchasing and supply management (PSM) function of a firm. Performance-improvement-oriented application of external supply knowledge present further challenges for the function. To examine this, we draw on the knowledge-based view and develop a hypothesized model in which supply knowledge acquisition drives PSM exploration and exploitation orientations which in turn mediate the organizational status of PSM function in terms of supply performance. We test the model on an SME-focused and survey-based dataset, using structural equation modelling. Our results indicate that an exploitative orientation is associated with knowledge gained from the supply base, whereas an explorative orientation is predominantly associated with supply market knowledge and less with supply base knowledge, suggesting natural pairings. The findings also show how an exploitative development orientation mediates the positive association of the PSM function's organizational status with supply performance. Driven by supply base knowledge, a status-empowered exploitative PSM orientation may suppress supply market based explorative orientation in resource-scarce SMEs, thus appearing to serve as the sole path to supply performance. Our research contributes by pointing out the significance of the knowledge-resource, and the knowledge-based view, in understanding performance in PSM. 相似文献
