COMPARING PPP WITH TRADITIONAL PROCUREMENT: THE CASE OF SCHOOLS PROCUREMENT IN IRELAND

Advocates of public‐private partnerships (PPPs) argue that they can deliver public infrastructure more efficiently than traditional procurement through timelier completion and superior value for money. Despite these claims comparative analysis of the performance of both procurement methods has received scant attention in the PPP literature to date. This paper addresses this issue by providing an in‐depth, case‐based comparison of PPP versus traditional procurement in the schools sector in Ireland. Through detailed semi‐structured interviews with key stakeholders and an examination of the available documentation, we assess whether the key objectives of using PPP have been achieved. Overall, we find no evidence that PPP leads to faster delivery of infrastructure when the overall procurement process from contract notice to delivery is accounted for. In addition, we find only limited evidence to suggest that PPP results in better value for money.     

对我国风险投资组织模式选择的研究

有限合伙制以其特有的产权和责任安排而被认为是最符合风险投资行业特点和要求的组织形式。我国在对建立有限合伙制风险投资企业的认识上存在一定的分歧，本认为随着我国经济的不断向前发展，相关法律法规的完善，有限合伙制必然会成为我国风险投资企业组织模式的首选。     

Business Strategy and Poverty Alleviation

Currently, entrepreneurs and corporations overwhelmingly do not view the alleviation of global poverty as a strategic priority. Yet business activity can have a negative as well as a positive effect on each distinctive form of poverty. In order to reduce poverty, entrepreneurs have to find ways of limiting the negative aspects. This might be achieved by deliberately augmenting strategies so that they can achieve a synthesis, in partnership with governments and NGO’s. Alan E. Singer is a reader in strategy at the university of Canterbury. He was the 2004/5 Aram chair of Business Ethics at Gonzaga. He is author of Strategy as Rationality (Avebury), Co editor (with Pat Werhane) of Business Ethics in Theory and Practice (Kluwer) and editor of Business Ethics and Strategy (Ashgate, forthcoming). He has written journal articles on many aspects of strategy and decision making and has served on the editorial boards of Journal of Business Ethics (to 2003), Human Systems Management, Journal of International Entrepreneurship, African Journal of Business Ethics and the Journal of Economic Development and Business Policy.     

A monetary business cycle model with unemployment

To reproduce key features of the post-war U.S. data, most monetary business cycle models must assume there are high price markups and that agents have high labour supply elasticities despite the existence of contradictory microeconomic evidence. This paper eliminates the need for these assumptions by introducing imperfectly observed effort into a limited participation model. The estimated model is better able to capture the sluggish price response to a monetary policy shock than the standard model, and is consistent with evidence regarding the qualitative responses of the U.S. economy to technology shocks, fiscal policy shocks and monetary policy shocks.     

董事责任制度重构： 精准问责、合理容错、宽容失败——以弘扬企业家精神为视角

基于权力（利）、义务、利益、责任与风险相匹配的基本逻辑,新《公司法》既要健全董监高的差异化公平问责规范体系,也要建立人性化合理减免责任制度。董监高问责能力取决于其职位的含权量、含金量、实际控制力与影响力,也取决于所在公司治理实况。要重点锁定并严惩关键少数者,严格区别独董与内部执行董事的法律角色。董监高责任应以过错责任为主、严格责任为例外。为精准识别董监高过错,建议采取法商、德商、智商、情商合一的理性人标准。要坚持责任自负为主、连带责任为辅。连带责任规范要保持统一化与谦抑化,赋予董监高在承担连带责任后的法定追偿权。要坚持有限责任为主、无限责任为辅。董监高对第三人不负责任为原则,负责为例外。建议精准甄别董监高个人责任与公司法人责任。章程或公司决议对法定代表人代表权的限制只要登记、备案或公示,即可对抗相对人。建议导入商事判断规则,允许公司自主豁免或减轻董监高责任,要求董监高自担最低责任限额,导入董监高责任保险制度。董监高问责机制要与股权激励相匹配。     

我国公司法定类型的反思及逻辑建构

自公司诞生以来,公司这一组织形式就受到各国商业实践和立法的特别重视。各国商事立法均对公司类型加以规定,并分门别类地对公司设立、股东权利、公司治理等进行相应规范。虽然商事逻辑的共通性拉近了各国立法上的公司类型,但各国在公司法定类型及相应公司规制上的差异仍旧鲜明。这也反映在我国学界对公司法定类型的争议上。我国公司法定类型改革应坚持本土商业实践逻辑,并确保改革成本最小化。由此,保留有限责任公司和股份有限公司,并按公司规模大小进一步区分出大型公司与小型公司,就成为理性选择的结果。具体而言,在有限责任公司中,增设大型公司,明确大型公司认定标准,并在公司机关设置、财务会计制度等方面给予相对严格的例外规定;在股份有限公司中,增设小型公司,对其赋予更加灵活、便捷的自治,并将上市公司扩增为公众公司。     

从经济理性到有限理性:经济学研究理性假设的演变

"经济理性"是经济学的传统研究假设,却因背离现实而受到质疑.基于行为人稀缺的心理资源和系统固有的不确定性而产生的"有限理性"正逐步取代"经济理性"成为经济学研究的理性假设.不同的理性观点可以从决策的视角得到系统地解释和比较.并且,随着理性假设的演变,经济行为的决策标准也相应从单一静态最优向多元动态平衡转变.     

会计盈余及时性对公司治理机制影响的实证研究

本文通过考查1997年到2004年间上市公司治理机制代理变量与会计盈余及时性指标之间截面数据相关关系,探讨治理机制是否随会计盈余及时性而变化。结果基本支持了本文的假设:董事对高成本信息收集和整理的需求与会计系统信息的有用性是倒数关系,外部股东对高成本信息收集和整理的需求与会计系统信息的有用性是正相关关系;会计系统信息有用性的重要决定因素是解释股权价值现时变化的程度;以高成本的监督活动为特点的特殊治理结构是股东和董事对高成本信息收集和整理需求的反应。     

Environmental liability and the capital structure of firms

This paper analyses the impact of environmental liability regimes on the capital structure of firms. We show that imposing environmental liability only on polluting firms, with limited liability, increases use of bank debt. Extending environmental liability to banks lowers bank borrowing relative to liability only on firms, with an ambiguous effect relative to no liability. Using US industry-level data we estimate a reduced-form model of bank borrowing by firms and show that the introduction of environmental liability only on firms increased bank borrowing by 15–20%, but when liability was extended to banks, borrowing returned to a level slightly higher than with no liability.     

关于修改我国公司法的几个基本问题

公司法作为商法的基本组成部分,在市场经济体系中占有非常重要的地位。本文结合我国的社会经济实践,对我国现行公司法的修改和完善从公司法的指导思想、立法原则、体系安排、法律形态选择等角度提出了建议,认为公司法的制定应充分反映市场经济的基本要求和本质内涵,应反映世界公司法发展的先进成果和经验。
