Asset Specificity and Vertical Integration

Asset specificity is usually considered to be an argument for vertical integration. The main idea is that specificity induces opportunistic behavior, and that vertical integration reduces the cost of preventing opportunism. In this paper I show that asset specificity can be an argument for non‐integration. In a repeated‐game model of self‐enforcing relational contracts, it is shown that when parties are non‐integrated, increasing degrees of asset specificity make it possible to design relational contracts with higher‐powered incentives.

技术引进、研发外溢和二次创新

本文利用专利竞赛模型 ( patent race) ,探讨技术引进及其二次创新活动中技术引进费用与自身应用性研发投入的关系以及二次创新速度和市场均衡时参与该竞赛的厂商数目的决定。同时也分析了研发外溢效应对模型的冲击。文章的主要结论是 :技术引进与自身应用性研发投入是互补抑或替代关系需视两者相对大小而定。双方的关系呈现阶段性变化。此外 ,随外溢效应的增强 ,整个参与竞赛的厂商数目和厂商应用性研发投入水平均趋于下降 ,但是整个社会引进技术的二次创新速度却趋于加快     

Regulatory and environmental effects on public transit efficiency: a mixed DEA-SFA approach

This paper assesses the impact of regulatory and environmental factors and statistical noise on the efficiency of public transit systems within a DEA-based framework. Using a panel of Italian companies, we implement a DEA-SFA mixed approach based on [H.O. Fried et al. (2002) Journal of Productivity Analysis, 17(1–2), 157–174] to decompose DEA inefficiency measures into three components: exogenous effects, managerial inefficiency and stochastic events. Besides providing evidence on the determinants of input-specific efficiency differentials across companies, the results point out that managerial skills play a minor role, and emphasize the relevance of regulatory policies aimed at replacing cost-plus subsidization with high-powered incentive contracts as well as improving environmental conditions of public transit networks.

Assessment of the agricultural sustainability of Shaanxi Province,China

It is significant for the study on the sustainable development of regional agriculture to monitor and measurethe trend of agricultural development with an effective method. The sustainable development of regional agricultureshould accord with regional population, rural economic development, social progress, resource and environmentalsupport. This paper establishes the evaluating indicators system of sustainable development of regional agriculture,evaluates the agricultural sustainable development in Shaanxi Province with a comprehensive multi-indicator method,analyzes the support of resource and environment for regional agriculture by the resource-development index and theenvironment-development index, and gets the conclusion that the indicators, such as education level, the income gapbetween urban and rural residents, the per capita area under cultivation and the consumption of pesticides and chemicalfertilizers per hectare, are the main factors to restrict agricultural sustainability, and that the pressure of the developmentof subsystems of population, economy and society on the subsystems of resource and environment turns out to bestronger and stronger. Agricultural environment gets better, but resource becomes one of the important factors to restrictthe development of regional agriculture. In a word, this paper highlights the potentials and limitations of sustainableagriculture of Shaanxi and helps identify the development direction in the future.     

Collaboration, peer review and open source software

Open source software development may be superior to proprietary development because the open source organizational form naturally minimizes transactions costs associated with privately distributed information. This manifests itself in the ability of open source communities to encourage critical peer review and the sharing of ideas. When these activities are important, the open source organizational form may do better than a proprietary organizational form. My results suggest why open source is particularly powerful when maintainability of software is critical, and also suggest that the founder of a software project may be more likely to choose open source if there is an existing dominant proprietary software project.

中美日环境会计信息披露差异研究

由于建立环境会计制度的时间不同、环境会计发育程度不同以及各国相关法律规定的不同，各国企业对环境会计信息的披露情况存在较大差异。笔者通过对中美日三国环境会计信息的披露形式和内容进行比较，认为应从加大宣传力度，进一步完善立法、加强执法、尽快制定环境会计准则和信息披露制度，提高企业管理者、会计人员的环保素质等方面入手。逐步完善我国的环境会计制度。     

用期权定价模型评估企业并购的价值

针对传统企业并购价值评估模型的局限性,本文从期权的角度阐述了企业并购的期权特性,指出企业并购实质上相当于取得了一个看涨期权;并以连续支付红利的美式期权定价理论为基础,建立了企业并购价值评估的期权定价模型。最后,通过实例论述了如何应用该模型来评估企业并购价值,对实践中企业并购价值的合理确定具有重要的指导意义。
