价值链会计——一个全新的理论构想

信息时代的到来,要求我们重新审视现行的会计模式,从而购建价值链会计体系成为可能。在价值链会计的购建体系中,本文对价值链会计与传统会计的区别、价值链会计目标、价值链会计实务操作、价值链会计发展趋势等方面进行了探讨。     

上市公司会计信息传递:现状、原因与对策

会计信息的有效传递对资本市场资源配置功能的实现有着重要的影响。本文通过对我国投资者在会计信息的使用状况、使用程度以及使用效果等方面的研究后发现,我国上市公司所披露的大量会计信息并没有实现有效的传递。主要原因在于财务报表缺乏相关性、报表披露透明度不高、投资者专业素质欠缺以及会计舞弊导致的诚信缺失。对此,我们提出了改善会计信息传递质量的建议。

Mechanism Design with Interdependent Valuations: Surplus Extraction

If valuations are interdependent and agents observe their own allocation payoffs, then two-stage revelation mechanisms expand the set of implementable decision functions. In a two-stage revelation mechanism agents report twice. In the first stage - before the allocation is decided - they report their private signals. In the second stage - after the allocation has been made, but before final transfers are decided - they report their payoffs from the allocation. Conditions are provided under which an uninformed seller can extract (or virtually extract) the full surplus from a sale to privately informed buyers, in spite of the buyers’ signals being independent random variables. This research was started when I was visiting the Department of Applied Mathematics of the University of Venice, and continued while visiting the European University Institute in Florence.

Contracting inside an organization: An experimental study

In this paper we propose and test a contracting mechanism, Multi-Contract Cost Sharing (MCCS), for use in the management of a sequence of projects. The mechanism is intended for situations where (1) the contractor knows more about the true costs of various projects than does the contracting agency (adverse selection), and (2) unobservable effort on the part of the contractor may lead to cost reductions (moral hazard). The proposed process is evaluated in an experimental environment that includes the essential economic features of the NASA process for the acquisition of Space Science Strategy missions. The environment is complex and the optimal mechanism is unknown. The design of the MCCS mechanism is based on the optimal contract for a simpler related environment. We compare the performance of the proposed process to theoretical benchmarks and to an implementation of the current NASA ‘cost cap’ procurement process. The data indicate that the proposed MCCS process generates significantly higher value per dollar spent than using cost caps, because it allocates resources more efficiently among projects and provides greater incentives to engage in cost-reducing innovations.

我国区域资本形成机制差异的资源诅咒分析

资本形成理论认为资本是经济发展的重要要素，资本形成机制差异也相应成为区域经济非均衡发展的动力源。基于此，本文从“资源诅咒”理论出发，对我国三大区域资本形成机制差异的根源进行了重新诠释，并有针对性地提出了相应措施，以建立有效的资本形成机制与发展模式，帮助中西部地区走出资源诅咒困境。     

试论知识产品的生产机制

以现代经济学方法对知识产品的生产机制进行剖析，呈现在经济学视野中的是一副崭新的画卷：知识产品原创生产运行是一种“精神表达成物质”——“物质还原为精神”的随机循环往复、彼此互动的机制；知识产品生产的投入产出表现为一种随机梯级增长概率关系；知识产品的生产成本补偿是一种市场和非市场组合的多层互补机制；知识产品的价值实现是一种低价递减机制；知识产品生产具有巨大成本递减机制等。     

人民币汇率制度改革的绩效与走向

由于内外部的压力,我国人民币汇率制度自2005年7月21日开始实行改革,2006年12月初,人民币兑美元升值超过5%。但是人民币的升值并没有改变中美贸易不平衡的现状,对我国经济的负面影响不大,对国内物价水平的影响也较小。总体来说,人民币汇率改革对我国长期经济发展是有利的,它是一个长期的、循序渐进的改革过程,需要摸着石头过河,任何急躁、冒进的想法和做法都是不切实际的。     

人民币升值之争的理论反思:新制度金融学的解释

人民币汇率政策目前之所以处于两难境地,其症结完全在于中国的产权制度存在着缺陷,人民币升值之争的实质是制度变革之争.解决人民币汇率问题的正确顺序应该是:先进行产权改革以建立合理的产权制度,从而创造真正有效的市场机制,然后在此基础上实行浮动汇率制度.     

公司治理与企业家精神

传统公司治理理论强调对于企业控制权的控制,而淡化了企业作为企业家精神租金创造的意义。本文通过对公司治理与企业家精神的内在逻辑分析,提出公司治理实质上包含着朝向企业家精神的保健机制与激励机制,其共同作用影响企业家精神的发挥从而决定了公司治理的绩效。在理论分析的基础上,本文利用上市家族、国有企业的数据对理论假设进行了实证检验。结果证明,就家族企业而言,激励机制对企业家精神具有显著的正向促进作用,保健机制则表现为不作为或失灵;就国有企业而言,激励机制对企业家精神无显著影响,保健机制则对企业家精神具有较为显著的“倒U型”作用。
