网络租金的测量研究

已有研究表明,网络租金确实存在,不能形成网络租金或者网络租金分配不合理,都会影响网络组织合作的成败。但是,目前对网络租金的测量研究很匮乏,以致对网络租金的认识仍存在很多疑惑。本研究试图构建网络租金的测量维度与量表,旨在为后续研究奠定可操作的基础,为实践者提供衡量网络租金的依据。分析发现,网络组织的功能、网络成员的结网动机与网络租金的内涵有着高度的一致性,进而从理论上提出了网络租金的测量量表,并通过信度检验、效度检验和验证性因子分析,对量表进行了实证检验,最终形成了三个维度、10个题项的测量量表。三个维度包括交易费用的减少、李嘉图租金与熊彼特租金。交易费用减少的题项包括搜寻成本、签约成本、履约成本与监督成本的减少;李嘉图租金的题项包括资源整合所产生的销售额、净利润、市场份额的增长;熊彼特租金的题项包括学习创新所带来的技术、产品或服务、管理方面的创新与改进。     

Using clustering ensemble to identify banking business models

The business models of banks are often seen as the result of a variety of simultaneously determined managerial choices, such as those regarding the types of activities, funding sources, level of diversification, and size. Moreover, owing to the fuzziness of data and the possibility that some banks may combine features of different business models, the use of hard clustering methods has often led to poorly identified business models. In this paper we propose a framework to deal with these challenges based on an ensemble of three unsupervised clustering methods to identify banking business models: fuzzy c‐means (which allows us to handle fuzzy clustering), self‐organizing maps (which yield intuitive visual representations of the clusters), and partitioning around medoids (which circumvents the presence of data outliers). We set up our analysis in the context of the European banking sector, which has seen its regulators increasingly focused on examining the business models of supervised entities in the aftermath of the twin financial crises. In our empirical application, we find evidence of four distinct banking business models and further distinguish between banks with a clearly defined business model (core banks) and others (non‐core banks), as well as banks with a stable business model over time (persistent banks) and others (non‐persistent banks). Our proposed framework performs well under several robustness checks related with the sample, clustering methods, and variables used.

旅游地文化空间及其演化机理

旅游活动的文化属性决定了旅游地本质上是为旅游者提供一个文化空间。从旅游地文化的空间研究转向空间的文化研究,并厘清旅游地文化空间的内涵及其演化机理,寻求旅游地的文化发展规律,有助于解决旅游规划与开发中"造文化、造景观"的困境。基于空间生产和景观生态学原理,以及旅游地文化空间的活态性,旅游地文化空间的时间和功能演化是由原居民的生产与生活空间演变为服务于旅游发展的生产与生活空间的过程。旅游地文化空间在形态上,则表现为文化节点、文化轴线、文化场、文化域面等基本空间形态的形成与演化。文化场作为最为重要的空间形态,它是旅游地进行生产、生活与服务的真实场景,体现了人与旅游景观的社会文化关系。     

Timeless perspective versus discretionary policymaking when the degree of inflation persistence is unknown

One major strand in optimal monetary policy analysis considers the robustness of alternative policies under model uncertainty. Another has focused on the appropriate perspective for optimal monetary policy, namely discretion or the timeless perspective (TP). The paper bridges these two parallel lines of research by assessing the welfare consequences of both policy perspectives in the presence of misperceptions about the degree of intrinsic inflation persistence. Contrary to most standard results, discretion can be the more robust perspective, the reason being that the TP exploits the expectations channel. With misperceptions this leads to large deteriorations in welfare.     

Mixed Duopoly,Merger and Multiproduct Firms

The literature on mergers has extensively analyzed the decision to merge by private firms, but it has not considered the decision to merge by private and public firms. We assume that when a private firm and a public firm merge (or when one of them acquires the other), they set up a multiproduct firm in which the government owns an exogenous percentage stake. In this framework, we show that the decision to merge by firms depends on the degree to which goods are substitutes and on the percentage of the shares owned by the government in the multiproduct firm.     

工会主席专职化对工会维权活动的影响效应——来自雇主—雇员匹配调查的证据

本文利用“中国雇主—雇员匹配数据追踪调查（2012）”,采用多变量 Probit 模型考察工会主席专职化对工会维权活动的影响效应。结果发现：工会主席专职化强化了工会在工伤补偿、改善工作环境及改善住宿和伙食等员工福利方面的作用,而在提高员工工资、发加班费及减少解雇等核心维权活动方面的作用并不显著;工会主席专职化对工会维权作用在不同性质的企业有显著差异,在公有制企业主要表现为改善工作环境,而非公有制企业工会主席的专职化对工会维权的推动作用更大,特别是在发放加班费、工伤补偿等方面。
