Optimal investment with vintage capital: Equilibrium distributions

The paper concerns the study of equilibrium points, or steady states, of economic systems arising in modeling optimal investment with vintage capital, namely, systems where all key variables (capitals, investments, prices) are indexed not only by time but also by age. Capital accumulation is hence described as a partial differential equation (briefly, PDE), and equilibrium points are in fact equilibrium distributions in the variable of ages. A general method is developed to compute and study equilibrium points of a wide range of infinite dimensional, infinite horizon, optimal control problems. We apply the method to optimal investment with vintage capital, for a variety of data, deriving existence and uniqueness of equilibrium distribution, as well as analytic formulas for optimal controls and trajectories in the long run. The examples suggest that the same method can be applied to other economic problems displaying heterogeneity. This shows how effective the theoretical machinery of optimal control in infinite dimension is in computing explicitly equilibrium distributions. To this extent, the results of this work constitute a first crucial step towards a thorough understanding of the behavior of optimal paths in the long run.     

协作型企业供应链管理

供应链管理作为一种新型的企业关系管理模式在现代市场竞争中为企业生存与发展提供了一种工具。本文针对协作型企业供应链管理进行了研究。协作型企业供应链由于其业务联系上的紧密性与其他供应链有所不同，在生产计划制定上强调生产计划的一致性与协调性，核心企业与供应企业在生产计划制定方面的信息共享；在销售管理上强调企业与销售商集成式管理。     

股份制取代合作制是历史的必然——对中国农村金融制度选择的思考

目前，合作金融在中国遇到了种种困惑，这不是合作金融本身的错。一方面中国从来就没有建立过真正的合作金融；另一方面合作金融与中国当前的经济环境也不相适应。而那种异化了的合作金融既没有存在的必要，也没有存在的可能。股份制取代合作制是一种历史的必然。     

Some Cracks in the Empire of Chance (Flaws in the Foundations of Reliability)

Making quantified statements about the uncertainty associated with the lifelength of an item is one of the most fundamental tasks of reliability assessment. Most practitioners routinely do this using one of the several available statistical techniques. The purpose of this paper is two-fold. The first is to give the user an overview of the key tenets of two of the most commonly used parametric approaches. The second is to point out that these commonly used approaches involve strategies that are either ad hoc, or are in violation of some of the underlying tenets. A method that is devoid of logical flaws can be proposed, but this method is difficult to implement. The user must therefore resign to using that technique against which the fewest objections can be hurled.     

政府审计成本管理探析

随着近年来审计公开力度的加大,审计透明度的增强,社会公众对审计监督的期望也越来越高。但长期以来审计任务繁重与审计资源相对短缺之间的矛盾也很突出。在审计经费有限的条件下,必须借助审计成本管理的手段来解决这一矛盾。本文就加强审计成本管理的必要性,审计成本管理的原则以及如何实现对审计成本的控制等方面进行了分析和探索。     

Unfolding institutional plurality in hybrid organizations through practices: The case of a cooperative bank

This paper provides a theoretically informed analysis of how institutional pluralism unfolds in hybrid organizations through practices. Building on Quattrone's (2015) procedural model, the paper studies institutional plurality in the case of an Italian cooperative bank that has experienced enduring success. By reversing the usual approach to logic, defined as a stable set of beliefs, this paper shows that this hybrid organization uses a recursive system of practices in search of social order. This hybrid organization interrogates its organizational imperatives and defines adequate ways to achieve them. This paper then observes that this system of practices is permeable to external pressures, i.e., inspections by the central bank, a reform of cooperative banks, political pressure for mergers and acquisitions, and Italy's sovereign debt crisis. While such an organization appears to be ongoingly accountable to its multiple stakeholders, external pressures undermine its community accountability system and push this hybrid organization towards compliance accountability. Based on our findings, this paper develops a process model for hybrid organizations to navigate institutional plurality and to explain the potential limitations of the accountability system.     

反垄断法域外适用依据分析

反垄断法的域外适用包括多种情形,其依据也各不相同.其中由美国首先在司法中确立的“效果原则”对该类适用问题产生了重要影响,一方面对于保护本国的市场环境,效果原则确实具有积极的作用,但其引发的国家间主权和经济利益的冲突也使得该原则的适用受到了限制.对此,各国都采取了很多变通措施,并通过国际合作来缓解这些冲突,这对于我国的相关立法也具有启示作用.     

论农民在新型农村合作医疗中的角色——社会政策的视角

从社会政策的视角分析了农民在新型农村合作医疗政策过程中的角色地位,揭示了农民不仅是新型农村合作医疗制度的参与者、执行者,而且是政策的评估者、监督者和良好政策环境的提供者.因此,在完善新型农村合作医疗制度时,站在农民的立场,真正了解农民的需要,鼓励他们参与是必要的.

农村信用合作社经营性风险因素探究

农村信用合作所具有的资金规模小、专业特色强、地域性经营等特点，使农信社面临着资本保障不足、融资能力不强、运营成本高等经营性风险因素，要防范和化解这些风险因素，就必须改革农村信用社的经营管理体制，加强业务监管，并给予必要的政策扶持。
