政治关系“力量”与民营企业价值研究:腐败的调节效应

从社会网络理论的强弱关系视角对2012-2014年福布斯中国富豪榜的企业家及其企业进行了政治关系的度量,检验了腐败是否会调节政治关系"力量"对企业价值的影响。研究发现,企业家本身所具有的政治关系对企业价值具有明显的正向影响作用,关系的"力量"越强,对企业价值的正向影响就越大;与此同时,腐败的出现会强化政治关系"力量"对民营企业价值的影响。通过分组验证发现,这种"力量"在腐败程度较高环境下更易对企业价值产生正向影响,但在腐败程度较低的环境中,政治关系对民营企业价值的影响很多时候并不显著。     

Value co-creation in sustainable tourism: A service-dominant logic approach

To mainstream sustainability, we need to understand the value gained from sustainability by users. We apply a user-centred design methodology to develop an agile, iterative, incremental and reflexive process to understand the sustainability value proposition for Lufthansa City Center travel agents. We analyse the failure of sustainability communications within the online platforms used by these agents and explore why the agents factor out sustainability information during the customer sales process. We identify how agents and customers understand sustainability, and we explore opportunities to co-create sustainability value. Furthermore, we prototype, and then test, methods of empowering travel agents to communicate sustainability to their customers as a value-adding proposition.     

股权性质、环境不确定性与技术资本配置效率

技术转化为资本，资本创造价值已经成为共识，技术资本在不同公司创造价值的作用程度不同，根源是技术资本配置效率问题。选取沪深两市2008-2013年间制造业上市公司为样本，检验了基于不同股权性质的公司环境不确定性对企业技术资本配置效率和价值的影响，研究结果表明：①企业环境不确定性程度越高，技术资本配置效率越低，并且技术资本配置偏离度在国有公司中表现为配置过度，在非国有公司表现为配置不足；②在股权性质为国有的公司中，由环境不确定性引发的技术资本配置偏离将降低企业价值，在非国有控股公司中，由环境不确定性导致的技术资本配置偏离将增加企业价值。     

Monitoring as a partially observable decision problem

Monitoring is an important and costly activity in resource management problems such as containing invasive species, protecting endangered species, preventing soil erosion, and regulating contracts for environmental services. Recent studies have viewed optimal monitoring as a Partially Observable Markov Decision Process (POMDP), which provides a framework for sequential decision making under stochastic resource dynamics and uncertainty about the resource state. We present an overview of the POMDP framework and its applications to resource monitoring. We discuss the concept of the information content provided by monitoring systems and illustrate how information content affects optimal monitoring strategies. Finally, we demonstrate how the timing of monitoring in relation to resource treatment and transition can have substantial effects on optimal monitoring strategies.     

The need for an alternative to shareholder value creation? The Ethomed student experience

This article aims to highlight the need for a radical break with the methodological individualism that dominates the fields of economics and management, especially finance. It advocates the need to try to understand the issues and methods that are required to coordinate economic action in order to meet social needs.The article questions methodological individualism and the dominant role played by shareholders. Is it possible to promote social welfare simply by considering it to be a result of a shareholder value maximization point of view? If not, this implies not only understanding fully the challenges that we face but also being innovative regarding the way in which we coordinate the actions that are necessary to meet these challenges head on, and perhaps promoting another character as a substitute for the shareholder.     

Small farmer cooperatives and voluntary coffee certifications: Rewarding progressive farmers of engendering widespread change in Costa Rica?

Our research examines the benefits and drawbacks for cooperatives who participate in voluntary coffee certifications. We interviewed administrators at twenty Costa Rican coffee cooperatives about management practices related to voluntary certification. Voluntary certifications are popular among coffee cooperatives. Access to certified markets is facilitated by state support of the cooperative sector, regulation of the coffee sector and well-enforced environmental and social laws. However, there are no significant or consistent financial incentives for farmers to pursue certification. Multiple certifications may lower auditing and implementation costs, but cooperatives rarely receive the full premium for multiply-certified coffee. Low market demand for certified coffee, weak price incentives and high auditing and management costs encourage cooperatives to certify only a portion of their members. This strategy rewards compliant farmers rather than inducing widespread change to farming practices among the entire membership. Though financial incentives are weak, certifications offer non-financial benefits to both farmers and cooperatives, including better management and more resilient cooperatives.     

Creating sustainable value in the hospitality industry: a (critical) multi-stakeholder study in the Dominican Republic

This paper identifies sustainable initiatives reported by “sustainability-champion” hotels in the Dominican Republic, while contrasting them against the views of key stakeholders. We adapt and apply Hart and Milstein's Sustainable Value Framework, and complement it with a Critical Management Studies approach. Our analysis relies on a mixed-methods approach (non-hierarchical k-means cluster analysis, as well as thematic and content analysis). Findings indicate that most hotels are engaging more actively in present-oriented strategies such as pollution prevention (especially, the international hotels) and in product/service stewardship. However, in the future-oriented strategies, hotels owned by local investors show higher commitment to both clean technology and innovation, and to the sustainability vision (as the firm's growth path). In addition, although the views of multiple stakeholders show a clear acknowledgment of the hospitality industry's sustainability efforts (particularly regarding education and environmental protection), they also offer differing views about the ultimate impact and value of those efforts for them and for the broader society. Our study offers a new theoretical lens to explore multi-stakeholder approaches and offers practical implications for the Dominican Republic's National Strategy for Development 2010–2030, as well as implications that may be of use for other tourism-dependent countries.     

Efficiency in overlapping generations economies with longevity choices and fair annuities

When individuals can influence their life-expectancies and save in annuities, suboptimal savings result from the lack of incentives to choose the optimal longevity, even when annuity returns can be made contingent to longevity-related choices. Specifically, the golden rule steady state maximizing the representative agent utility cannot be attained as a competitive equilibrium under laissez-faire, even with actuarially fair annuities contingent to longevity-enhancing choices. In order to decentralize through markets the golden rule, longevity-enhancing expenditures need to be taxed if the steady state old-age consumption exceeds the annuitized capital return, and subsidized otherwise—the government budget being balanced through lump-sum transfers or taxes. Interestingly, with positive population growth the expected net contribution is negative when longevity-enhancing expenditures are taxed, and positive when subsidized.     

Exploring Value‐Based Management Sophistication: The Role of Potential Economic Benefits and Institutional Influence

The complexity of value‐based management (VBM) is often not captured in empirical research. In particular, potential differences in the extent of VBM implementation are not considered. Firms are predominantly classified dichotomously into either VBM “adopters” or “non‐adopters.” In this study, we aim to fill this gap by introducing a framework to assess differences in the extent of VBM implementation (VBM‐sophistication) based on publicly available data. This approach enables us to study determinants of VBM‐sophistication based on a hand‐collected data set comprising 2,683 firm‐year observations from 16 European countries between 2005 and 2014. Specifically, we investigate (i) whether potential economic benefits associated with VBM implementation lead to a higher level of VBM‐sophistication, and (ii) if this relation is influenced by extra‐organizational institutions (e.g., industry norms). Our results indicate that companies exhibit higher VBM‐sophistication if certain firm characteristics that increase the potential economic benefits of VBM are present. Moreover, our study provides evidence that this effect is enhanced by extra‐organizational institutions that pressure and support firms in realizing the potential benefits of higher VBM‐sophistication.     

From market to hierarchy: An empirical assessment of a supply chain governance typology

This study performs an empirical assessment of the highly influential supply chain governance typology put forth in Gereffi et al. (2005). In spite of the influence this Global Value Chain (or GVC) Typology has had, there have been few (if any) attempts to empirically assess its alignment with real-world supply chain structures and to establish a baseline for its predictive utility. The GVC Typology is assessed for face and nomological validity through testing of its key dimensions in relation to purchasing-logistics integration and supplier performance measures, using an information-processing theory framework. The GVC Typology appears to have considerable face validity as actual supply chain governance structures aligned well with those it proposes. It also has reasonable predictive power with regards to governance dimensions and integration, and in some connections between governance types, integration, and supplier performance. This study provides researchers with the tools to move this typology beyond the “conceptual” stage in their work, allowing for holistic and higher-level assessments of supply chain governance structures and changes. It may also help researchers and managers to consider when and to what extent purchasing-logistics integration should be fostered.
