交易成本对易货经济的影响——瓦尔拉斯均衡“不成立”的一种情形

本文首先用一种新的解析几何方法在易货经济 (即两种商品的纯交换经济 )条件下的一般均衡框架下揭示了价格与消费者的马歇尔需求之间的函数关系。在此基础上 ,由个人承担的交易成本被直接置入。然后 ,本文证明 :如果交易成本的固定项不为零 ,供、求函数将不连续 ;如果同时有非无穷小比例的人口进行同步化决策 ,那么瓦尔拉斯均衡将会被破坏     

Governing cooperation hazards of outsourced municipal low contractibility transactions: An exploratory configuration approach

Increasingly, public sector organizations (PSOs) outsource the delivering of important welfare services. This gives rise to important questions of how PSOs can control their suppliers. The purpose of this paper is to show how PSOs manage cooperation hazards of low contractibility transactions, i.e., activities expected to be difficult to govern. The paper applies a taxonomic configuration approach which means we apply a holistic view on the governance of suppliers and search for internally congruent governance packages that also are adapted to the context of the transactions. We find indications of the importance of internal congruence in governance packages in order to effectively deal with cooperation hazards. We also notice that the intensity in and types of controls in inter-organizational relationships are affected by the amount of cooperation hazards. A conflict between a relational and a bureaucracy-based governance package in one of the configurations is argued to be the main driver behind lower expectations about positive behaviour from suppliers.     

Allocative vs. technical spectrum efficiency

Achieving allocative and technically efficient spectrum management is a key aspect of deregulatory reforms in several OECD countries. However, reform legislation offers few clues as to how these objectives should rank when they conflict with one another. An ‘innocent’ prior acquisition of service-neutral spectrum at an efficiently run auction may prove allocative efficient but fail to be technically efficient if the spectrum is left fallow in the short term. Accountability for the productive usage of a public resource and pressures from short-term political cycles may induce regulators to mandate some minimal level of activity. Two plausible regulatory responses are considered: use it or lose it clauses and spectrum trading incentives. The former favours technical efficiency whilst the latter promotes allocative efficiency. The argument is formalised in a simple economic model buttressing the roles of uncertainty and transaction costs to assert the primacy of allocative efficiency over technical efficiency.     

On the Hoggard–Whalley–Wilmott Equation for the Pricing of Options with Transaction Costs

The Hoggard–Whalley–Wilmott equation is introduced to model portfolios of European type options incorporating transaction costs. The model gives rise to a nonlinear parabolic partial differential equation (PDE), whose nonlinearity reflects the presence of transaction costs. We show analytically the existence of solutions which are not necessarily convex nor concave. Numerical treatments are also given, which are devised to effectively handle an infinite domain and unbounded solutions.      

个人营销论

市场营销的分析范式对个人行为具有一定的普适性,将这种分析范式运用于个人行为分析就形成个人营销理论。个人营销是知识经济时代营销理论在个体行为的扩展,较之于组织营销既有相同点,也有明显不同的特点。个人营销的内容一般涉及形象、理念、能力三个方面。个人的外观形象在一定程度上是个人行为能力的有形展示。个人营销观念决定了各个人成功与否以及成功的广度和深度。个人营销战略可以从个人资源利用与机会成本比较的角度以及从人际关系网络的利益与风险比较的角度来考察。     

Economists' perceptions versus managers' decisions: an experiment in transaction-cost analysis

Are the perceptions of professional economists on transactioncosts consistent with make-or-buy decisions made within firms?The answer may have important implications for transaction costresearch. Data on firms' outsourcing during the new productdevelopment process are taken from a large-scale survey of UK,German and Irish manufacturing plants, and we test the consistencyof these outsourcing decisions with the predictions derivedfrom the transaction cost perceptions of a panel of economists.Little consistency is evident between actual outsourcing patternsand the predictions of the (Williamsonian) transactions costmodel derived from the panel of economists. There is, however,evidence of a systematic pattern to the differences, suggestingthat a competence or resource-based approach may be relevantto understanding firm outsourcing, and that firms are adoptinga strategic approach to managing their external relationships.     

Governance structures in R&D networks: An analysis in the European context

This paper analyses governance structures used to organize partnerships in R&D networks using two approaches: transaction costs theory and social capital theory. We argue that these theories are complementary; this explains forms of governance through the degrees of administrative (structural and safeguard mechanism) and social factors (cohesion and openness) they embody. Data was obtained from European R&D networks created through Framework Programmes which include a great number of universities, non profit institutions and firms. Findings show the variables that characterize and explain the governance forms based on the applicability of R&D networks. This study not only provides a theoretical model for analysing governance structures of these networks, but is also useful for both improving the management of networks and for fostering collaboration at an international level.

The Path to Enhance Quality of Suspicious Transaction Reports for Anti-Money Laundering

反洗钱制度安排的一项核心内容是金融机构向反洗钱情报部门提交可疑交易报告。目前,金融机构可疑交易报告数量庞大而情报价值较低,已成为制约反洗钱工作开展的主要障碍。本文在分析可疑交易报告质量影响因素的基础上,给出了提升其质量的系统管理路径,包括完善报告制度、优化报告流程、实施风险管理、创新技术手段、拓展审计职能等。     

透明度变化对股票市场投资者委托单提交行为和交易成本影响研究

基于2003年12月8日沪深交易所交易前市场透明度改革背景,本文利用一家营业部的投资者报价和交易数据,研究同一个机构投资者和散户投资者在透明度改革前后委托单提交激进程度的变化,以及这种变化对其完成交易的成本的影响。我们发现,透明度改革前后,机构投资者的委托单提交激进程度都显著大于散户投资者的委托单提交激进程度。透明度增加以后,机构投资者的委托单激进程度显著减少,而散户投资者的委托单提交激进程度增加。同时发现,透明度增加以后,机构投资者通过分拆委托单,增加交易次数,导致完成交易的时间增加,但价格影响力基本没有变化,散户投资者的成交时间和价格影响力有显著改善。
