Collaborative buyer-supplier relationships and downstream information in marketing channels

Research on buyer-supplier relationships has emphasized the importance of collaboration and business networks. We aim to study the effects of downstream information on the collaborative buyer-supplier relationship. Downstream information refers to the information a firm obtains from marketing channels, be they wholesalers, distributors or retailers. The approach allows firms to concentrate their efforts on the most relevant sources of information and not on the whole network. Survey data was gathered from the Dutch potted plant and flower industry to test this hypothesis. Our findings demonstrate that collaborative relationships are contingent on downstream information from both the buying perspective (wholesalers) and from the supplying perspective (producers).

Promoting cost efficiency and uniformity in parcel delivery centre locations and service areas: a GIS-based analysis

This paper provides a systematic framework to determine local delivery centre (LDC) locations and service areas to reduce delivery costs and balance the allocation of parcel delivery loads to promote sustainable LDC development. Based on a case study of a parcel distribution company in Korea, this study proposes two strategies for LDC service area delineation within each terminal service boundary that either minimises the total delivery time or balances the allocation of delivery loads. This research contributes to improving cost efficiency and balancing delivery load allocations in planning LDC locations and service areas that can potentially promote the long-term mutual sustainable development of parcel distribution companies and their local delivery counterparts.     

Evaluating information diffusion speed and its determinants in social media networks during humanitarian crises

The rapid diffusion of information is critical to combat the extreme levels of uncertainty and complexity that surround disaster relief operations. As a means of gathering and sharing information, humanitarian organizations are becoming increasingly reliant on social media platforms based on the Internet. In this paper, we present a field study that examines how effectively information diffuses through social media networks embedded in these platforms. Using a large dataset from Twitter during Hurricane Sandy, we first applied Information Diffusion Theory to characterize diffusion rates. Then, we empirically examined the impact of key elements on information propagation rates on social media. Our results revealed that internal diffusion through social media networks advances at a significantly higher speed than information in these networks coming from external sources. This finding is important because it suggests that social media networks are effective at passing information along during humanitarian crises that require urgent information diffusion. Our results also indicate that dissemination rates depend on the influence of those who originate the information. Moreover, they suggest that information posted earlier during a disaster exhibits a significantly higher speed of diffusion than information that is introduced later during more eventful stages in the disaster. This is because, over time, participation in the diffusion of information declines as more and more communications compete for attention among users.     

Shadow costs of incomplete information and short sales in the valuation of the firm and its assets

This paper presents a simple framework for the valuation of compound options within shadow costs of incomplete information and short sales. The shadow cost includes two components. The first component is the product of pure information cost due to imperfect knowledge and heterogeneous expectations. The second component represents the additional cost caused by the short-selling constraint. Information costs are linked to Merton's (1987. Journal of Finance 42, 510) model of capital market equilibrium with incomplete information, CAPMI. This model is extended by Wu et al. (1996. Review of Quantitative Finance and Accounting, 7, 136) who propose an incomplete-information capital market equilibrium with heterogeneous expectations and short sale restrictions, GCAPM. This model is used in our paper to provide for the first time in the literature analytic solutions for derivatives in the presence of both shadow costs of incomplete information and short sales.When deriving the compound call option formula, we consider a call option on a stock, which is itself an option on the assets of the firm. Our methodology incorporates shadow costs of incomplete information and short sales on the firm's assets as well as the effects of leverage in the capital structure. The formula can be useful in the valuation of several corporate liabilities in the presence of information uncertainty and short sales constraints about the firm and its cash flows. Our analysis can be used for the valuation of several real options.

创新型企业的组织结构设计研究

成功的创新需要合适的组织结构的支撑,而当前的企业组织结构存在阻碍创新的弊端。创新型企业要求的组织结构应具有分权化和开放系统性特征,二元组织(Ambidextrous Organization)思想和生存系统模型(Viable Systems Model,VSM)为创新型企业的组织设计提供了新的思路。创新型企业应进行组织结构的重设,分别设立日常事务部和创新业务部,并将创新业务部分为创新业务经理、信息部、协调部、控制部和操作部,为提高创新型企业的自主创新能力提供组织保障。

西方国家社会责任会计信息披露及其对我国的启示

社会责任会计(SocialResponsibilityAccounting)是西方国家于上世纪七十年代创立的一个会计分支。一些国际组织、国家政府及会计职业团体在近三十年间对社会责任会计信息的披露问题从理论和实践上进行了研究和尝试。这些研究和实践对建立我国社会责任信息披露机制及提高披露水平有着重要的借鉴意义。
