This study contributes to the conceptualization of a sustainable circular business model (CBM), the application of the circular economy (CE) by companies. The study utilized a three-level framework adapted from the CE literature with company (micro), supply chain (meso) and society (macro) levels. This multiple-case study in the textile industry included two types of companies operating in the CE: companies founded on the sustainable principles of a CE (natives) and companies transitioning to a CE from the linear economy (adopters). The findings show that the adopters emphasized long-term economic sustainability on a company level and implemented CE elements to varying degrees on all three levels. The natives pursued business decisions from environmental and social sustainability standpoints, and the three levels were integral in their systemic approach to a CE. The study highlights two key claims: established operational structures and economic volition hindered adopters in their systemic CE implementation, and an integral part of the CBM for natives was a proactive approach towards the society level.  相似文献

Extended producer responsibility (EPR) is a proposed policy approach to promoting the circular economy (CE) within the European Union. This research used a policy Delphi to explore perspectives on improving EPR policies to further contribute to the CE goals of the Netherlands. Both the potential improvement and critical reflections discussed by CE and EPR experts and practitioners from this study contribute to a more detailed understanding of the future governance of CE practices. We present various activities to improve EPR and insights from Delphi participants that emerged from the study. This paper shows that whilst actors agree, in essence, that there is a need for modifying EPR, what the specific changes to the form are and to whom the new responsibilities apply is contested.  相似文献

Drawing on external ideas through crowdsourcing has become common practice for firms that seek to improve and extend their product portfolios. As these initiatives often address the users of products, it is essential for firms to recognize those attributes that determine these individuals' willingness to share their ideas. This study takes the example of the automotive industry to examine how three attributes of car drivers determine their sharing behavior – that is, altruism, psychological ownership of ideas, and trust in car manufacturers. Our findings suggest that trust and altruism strengthen idea sharing, while psychological ownership weakens it. Furthermore, we find that car drivers' perception of sharing‐related risk acts as an important boundary condition for these relationships.  相似文献

Investor-driven 'short-termism' is said to harm EU public firms' ability to invest for the long term, prompting calls for the EU to better insulate managers from shareholder pressure. But the evidence offered—rising levels of repurchases and dividends—is incomplete and misleading: it ignores large offsetting equity issuances that move capital from investors to EU firms. We show that, over the last 30 years and the last decade, net shareholder payouts have been moderate and investment and cash balances have increased. In sum, the data provide little basis for the view that short-termism in the EU warrants corporate governance reforms.  相似文献

Although scholars across numerous disciplines have studied specific types of career transitions, there has been no examination of the career transitions literature as a general phenomenon since Louis' seminal article was published four decades ago. Much has changed in the career landscape in the last forty years, including the number and types of career transitions being made by individuals. Using an inductive approach, the five major theoretical perspectives of career stage, decision-making, adjustment, relational, and identity emerged from our analysis of 242 publications. In this paper, we summarize research on each of these major perspectives on career transitions, recognizing emerging trends and research gaps. Based upon an analysis across these perspectives, we recommend seven major avenues for future research on career transitions.  相似文献

In the U.S., virtually no new coal-fired power plants have been built in recent years. Both industry experts and academics seem to believe that no rational firm will build a new coal-fired plant. Will such a trend continue in the future? To provide insights into this question, we investigate the optimal decision of an electricity company with an irreversible and deferrable opportunity to build either a new coal-fired or natural gas-fired power plant as its new base-load resource. According to our real option analysis, the optimal decision depends on the location. In the case of the eastern U.S., it is optimal to choose a natural gas plant if a firm is given a choice among a new natural gas plant, a new coal plant and deferring the investment. However, contrary to the common sentiment in the industry and academia, building a new coal plant in the western U.S. is still more economical than building a new natural gas plant in the absence of emission pricing. Furthermore, introducing carbon pricing to western U.S. states, as California did, can substantially increase the probability that a firm will optimally choose a natural gas plant over a coal plant.  相似文献

Several studies have found a relationship between corporate social and environmental disclosure and firm value (FV) or accounting profitability. Where environmental disclosure has been the focus, though, only single-country studies have been published, and most of the previous research concerns the developed world. This study examines the association between corporate environmental disclosure (CED) and FV in the Gulf Cooperation Council (GCC) countries, where CED has been increasing from its previous low base. Findings from a multicountry sample of 500 firm-year observations using a 55-item unweighted environmental disclosure index suggest that CED is significantly and positively related to FV as measured by Tobin's Q (TBQ). The relationship is robust to using a weighted version of the disclosure index, individual countries and environmental disclosure subindices. Some evidence of a positive relationship between CED and return on assets is also found, but even where statistically significant, the relationship is much weaker than in the case of TBQ. For empirical and theoretical reasons, we recommend that future studies pay greater attention to market-based proxies, if possible, when investigating the value relevance of CED in both developed and developing countries. Our results suggest that both managers and policymakers in GCC countries should take a positive view of expanded CED.  相似文献
