一种项目采购模式的博弈分析

本文试图用经济学理论 (主要是博弈与信息经济学的理论 )来分析目前工程项目建设中采用的一种工程设备、材料的采购模式。文章首先提出这种模式的内容与特征 ,然后就制度内各参与方 (主要为业主、承包商、供货商 )之间的博弈进行分析 ,分不完全信息博弈、完全信息博弈两种情况来分析这种采购制度下达到的均衡。

关于对城市物流配送体系建设的思考

城市物流配送体系建设是发展现代物流业的主要内容,是适应城市经济和社会发展需求、提高城市配送率和降低配送成本、减少城市拥堵、改善城市环境的主要手段。城市物流配送作为门到门服务的“最后一公里”,已经成为各大中城市物流产业链中的一个薄弱环节,城市物流配送关系到城市人民的菜篮子和米袋子,关乎民生问题,是一项惠民工程;城市配送关乎城市交通拥堵治理,是一项畅通工程;同时,城市配送管理涉及多个部门、诸多领域,是一项系统工程。因此,应积极加快促进和优化城市物流配送组织和运作模式,建立布局合理、运行高效、通行便利、绿色环保的城市配送网络体系。     

Strategic visualisation tools for managing technological information

In an information economy, the effective management of a massive amount of technological information is inevitable when attempting to facilitate the decision-making process. It is an important part of selecting R&D projects and allocating budgets to promising technology development. Information visualisation is thus regarded as a critical tool in technological information management because it can provide decisive implications that the intelligence of humans cannot produce. This paper proposes six graphical forms, including a technology tree, a technology map, a technology network, a technology matrix, a technology curve, and a technology dictionary, presenting the generic form and concept of each method. Moreover, the principles and applications of such visualisation tools are suggested in order to enhance their use in practical circumstances. A case study of TFT-LCD (thin film transistor-liquid crystal display) technology will help to explain how to apply visualisation tools to strategic technology management.     

网购市场鱼龙混杂现象的经济学解释：基于二维不对称信息的视角

网络购物市场存在商品鱼龙混杂的典型现象：高价格的商品不一定高质量,低价格的商品也不一定低质量,表现出明显的信息不对称特征。文章基于网络购物市场所存在的两个维度不对称信息的特征事实,即厂商在产品质量与产品生产成本两个方面拥有私有信息,通过构建二维不对称信息的分析框架,从市场均衡的视角首次解释了上述现象的经济机理。分析表明,由于二维不对称信息的存在,消费者和厂商决策的互动过程使得市场上产品价格与质量不再具有单调递增关系,从而网络购物市场可能出现鱼龙混杂的市场均衡,文章证明了这一均衡在合理的条件下是存在的。文章通过比较静态分析考察了市场环境的变化如何影响商品质量的价格信号显示效率以及消费者购买行为,并考察了网络购物行业商家披露信息、消费者对于商家的反馈评分机制和保证退货等手段对于消除商品鱼龙混杂现象的有效性,为进一步规范发展我国网络购物行业提供了参考。

Optimal Self-Reporting Schemes with Multiple Stages and Option Values

We consider a model of optimal law enforcement where sanctions can be reduced for self-reporting individuals. We distinguish between a first self-reporting stage before the case is investigated and a second one where the criminal is detected, but not yet convicted. Since we assume that violators have private information in both stages, fine reductions for self-reporting individuals lead ceteris paribus to a higher violation frequency. Nevertheless, we show that fine reductions should be granted in both stages. We characterize the connection between the two fine reductions in the optimal policy and relate our results to self-reporting schemes observed in reality.

Incentives for motivated agents under an administrative constraint

Consider an agent who has an expertise in producing a non-marketable good. This good is valued by a single principal, and there is a verifiable measure of the agent’s performance. Crucially, the agent is intrinsically motivated due to ‘warm glow altruism’. In addition, the agent’s budget, which is controlled by the principal, must not be less than the monetary performance-cost faced by the agent. This gives rise to a limited-liability constraint. It also restricts the agent’s ability to under-report costs. In such environment, we determine the link between the agent’s budget and performance. Our results come in contrast to the received solution of the principal-agent problem and to most in the literature on mission-motivated organisations and public services provision.
