The information content of funds from operations and net income in real estate investment trusts

This study compares the information content of funds from operations (FFO) and net income (NI) in the real estate investment trust (REIT) industry. We find that models using FFO explain more of the variance in cumulative abnormal returns around earnings announcement dates than models using NI do. We also find that the information content of FFO differs across REITs of different sizes. FFO does not provide useful information to investors in the case of large REITs. Finally, we show that the gain or loss from sales of property is relevant to valuing large REITs.

基于价值网的科技成果转化服务平台运行机制研究

科技成果转化服务平台在创新体系中发挥着越来越重要的作用,发展中存在的问题也日益显著。科技成果转化服务平台如何有效运行是科技资源管理和实践研究的典型问题,在分析科技成果转化服务平台研究现状的基础上,从价值网模型的内涵出发重构了成果转化服务平台,明确了各运营主体的职责和价值运转关系,有效解决了运行模式不清、平台运转效率低下等问题。然后,对基于价值网的成果转化平台运行特征进行了分析,进而对基于价值网的科技服务平台运行机制进行了研究。     

群体心理资本对员工创造力的跨层次影响

员工创造力是团队/组织创新的重要推动力,从多个层次综合考察员工创造力的影响因素具有重要意义。基于创造力成分模型、社会感染理论与组织管理领域的多层次理论,构建了群体心理资本影响员工创造力的关系模型,以103个工作团队（103名团队主管,365名成员）为样本,对研究假设及影响路径进行了实证检验。研究结果表明：①群体心理资本对员工创造力具有显著的正向预测效果;②群体心理资本对团队反思具有显著的正向预测效果,且团队反思在群体心理资本与员工创造力关系间起到了跨层次中介作用;③团队心理安全跨层次调节团队反思与员工创造力之间的正向关系,即团队心理安全越高,团队反思与员工创造力之间的正向关系越强。     

个体目标取向与团队心理安全交互对个体知识共享的影响

知识经济和“互联网+”快速发展,知识共享成为组织获取前进动力的主要方式以及组织竞争优势的重要来源。结合目标取向理论与特征激活理论,将团队心理安全纳入到个体目标取向对个体知识共享影响的研究中。对120个研发团队（含485个团队成员）样本的调查分析结果表明,个体学习目标取向与证明取向都显著正向影响个体知识共享,且团队心理安全在两者关系间具有显著的正向调节作用;个体回避取向显著负向影响个体知识共享,团队心理安全在两者关系间具有显著负向调节作用。     

The business case of a network that serves both public safety and commercial subscribers

Deploying a single nationwide broadband wireless network to serve all public safety users would have great advantages over the existing fragmented public safety systems. A nationwide system could be created to serve both public safety and commercial subscribers, which would allow a provider to exploit important economies but force it to meet the more costly requirements of public safety. This paper analyzes the viability of a public-private partnership that serves public safety and commercial subscribers from a for-profit provider's perspective. A model is presented that estimates the net present value (NPV) of a wireless network by calculating costs based on the number of cell sites required and revenue based on the projected number of subscribers acquired. The model is applied to both a network that serves only commercial subscribers on 10 MHz of 700 MHz spectrum and a public-private partnership that serves commercial subscribers and public safety personnel on 20 MHz of 700 MHz spectrum. It is found that NPV is greater for the public-private partnership than for the commercial-only network for any population density, which shows that the value of 10 MHz of spectrum exceeds the cost of meeting public safety requirements. Furthermore, the paper demonstrates that NPV/cell increases with population density, so urban areas are profitable and rural areas are unprofitable. The paper demonstrates that a partnership covering 94% of the US population breaks even because the most urban 56% of population subsidizes coverage for the next 38%. If initial deployment is subsidized, a financially sustainable public-private partnership can serve much more than 94%. Additionally, it is shown that allowing urban municipalities to opt-out of the partnership can significantly increase the subsidies required.     

Multihoming, content delivery networks, and the market for Internet connectivity

Peering points between different Internet service providers (ISPs) are among the bottlenecks of the Internet. Multihoming (MH) and content delivery networks (CDNs) are two technical solutions to bypass peering points and to improve the quality of data delivery. So far, however, there is no research that analyzes the economic effects of MH and CDNs on the market for Internet connectivity. This paper develops a static market model with locked-in end users and paid content. It shows that MH and CDNs create the possibility for terminating ISPs to engage in monopolistic pricing towards content providers, leading to a shift of rents from end users and content providers to ISPs. Implications for future innovations are discussed.

市场主体退出法律机制研究

市场主体退出是市场经济中的常态行为,需要将其纳入法治轨道即建立市场主体退出法律机制.市场主体主要因破产、解散或吊销营业执照而退出市场,但退出方式只能是注销.我国市场主体退出法律机制尚有许多问题需要完善.
