简要分析了公司治理结构与会计信息质量的关系,并在借鉴国外公司治理经验的基础上,结合中国企业的实际情况,从公司股权结构、公司治理模式、独立董事制度、股票期权激励约束机制以及绩效评价体系等有关公司治理的五个方面提出了若干建议和设想。     

汇率对产业内贸易的传导和冲击效应——基于中国东盟自由贸易区的分析

本文以中国与东盟六国18类产品的产业内贸易的月度面板数据作为分析基础，通过分析汇率与产业内贸易的传导关系、中国与东盟六国产业内贸易特点，并且建立产业内贸易指数与汇率的VAk模型．对我国的汇率对产业内贸易的冲击作用和动态关系做实证分析。研究发现：一是无论是短期或长期．汇率升值对绝大多数初级产品的产业内贸易是不利的，但在短期内它有助于提升大多数工业制品的产业内贸易水平．长期内对工业制品的产业内贸易冲击效应是分化的。二是汇率升值后长期内对不同劳动密集型产品的产业内贸易发展是一样的。三是无论是短期还是长期，初级产品的产业内贸易对汇率冲击的反应相当微弱．工业制品反应相对较强。     

企业网络财务信息披露调查与分析——来自河北省的案例

网上获取财务信息是管理者和投资者获取信息的主要途径之一,本文选取河北省上市为样本企业调查了企业网上财务信息的披露情况。调查发现,绝大部分企业建立了自己的网站,但普遍存在网上财务信息披露水平不高、财务信息披露量参差不齐、披露形式单一、对信息的安全性重视不足、数据更新不及时等问题,针对这些问题提出了改进建议。

Misperceiving the value of information in predicting the performance of others

Economic models typically allow for “free disposal” or “reversibility” of information, which implies non-negative value. Building on previous research on the “curse of knowledge” we explore situations where this might not be so. In three experiments, we document situations in which participants place positive value on information in attempting to predict the performance of uninformed others, even when acquiring that information diminishes their earnings. In the first experiment, a majority of participants choose to hire informed—rather than uninformed—agents, leading to lower earnings. In the second experiment, a significant number of participants pay for information—the solution to a puzzle—that hurts their ability to predict how many others will solve the puzzle. In the third experiment, we find that the effect is reduced with experience and feedback on the actual performance to be predicted. We discuss implications of our results for the role of information and informed decision making in economic situations.

Social learning with private and common values

Summary. We consider an environment where individuals sequentially choose among several actions. The payoff to an individual depends on her action choice, the state of the world, and an idiosyncratic, privately observed preference shock. Under weak conditions, as the number of individuals increases, the sequence of choices always reveals the state of the world. This contrasts with the familiar result for pure common-value environments where the state is never learned, resulting in herds or informational cascades. The medium run dynamics to convergence can be very complex and non-monotone: posterior beliefs may be concentrated on a wrong state for a long time, shifting suddenly to the correct state.Received: 6 January 2005, Revised: 5 May 2005, JEL Classification Numbers: C72, D82.Jacob K.

Selection dynamics and adaptive behavior without much information

This paper uses the experimental method to investigate behavior in a coordination game when the information available to subjects is limited to their feasible choices and their experienced payoffs. In the experiment subjects converge to an absorbing state at rates that are orders of magnitude faster than reinforcement learning algorithms, but slower than under complete information. This state is very close to a mutual best response outcome. All cohorts converged to the market statistic predicted by the interior equilibrium regardless of the information conditions or the stability conditions.

EDGAR on the internet: The welfare effects of wider information distribution in an experimental market for risky assets

Policies such as the SEC’s Fair Disclosure Rule, and technologies such as SEC EDGAR, aim to disseminate corporate disclosures to a wider audience of investors in risky assets. In this study, we adopt an experimental approach to measure whether this wider disclosure is beneficial to these investors. Price-clearing equilibrium models based on utility maximization and non-revealing and fully-revealing prices predict that in a pure exchange economy, an arbitrary trader would prefer that no investors are informed rather than all are informed; non-revealing theory further predicts that an arbitrary trader would prefer a situation in which all traders are informed rather than half the traders are informed. These predictions can be summarized as “None > All > Half”. A laboratory study was conducted to test these predictions. Where previous studies have largely focused on information dissemination and its effects on equilibrium price and insider profits, we focus instead on traders’ expected utility, as measured by their preferences for markets in which none, half, or all traders are informed. Our experimental result contradicts the prediction and indicates “Half > None > All”, i.e. subjects favor a situation where a random half is informed. The implication is that in addition to testing predictions of price equilibrium, experiments should also be used to verify analytical welfare predictions of expected utility under different policy choices.

Estimating exchange rate dynamics with diffusion processes: an application to Greek EMU data

Recently various exchange rate models capturing the dynamics during the transition from an exchange rate arrangement of floating rates into a currency union have been derived. Technically, these stochastic equilibrium models are diffusion processes which have to be estimated by discretely sampled observations. Using daily exchange rate data prior to the Greek EMU-entrance on 1 January 2001, we develop a rigorous estimation procedure. Our estimates point to an increasing interventionist economic policy in the run-up to the Greek EMU entrance. A comparison of this econometric indication with policy information provided (ex-post) by the Bank of Greece (BoG) in its Annual Report 2000 reveals that the BoG indeed pursued such an active policy stance (so-called institutional frontloading strategies).      

会计信息与公司治理结构分析

公司治理结构与会计信息都产生于委托代理理论、契约理论和产权理论的需要,理论基础的交叉重叠使会计信息与公司治理结构具有内在的逻辑性。会计信息质量决定公司治理效率,目前由于会计信息的有效需求不足和供给质量不高导致信息供需不均衡,从而使会计信息与公司治理陷入恶性循环,本文通过剖析信息供需机制不均衡的原因,提出完善的对策和建议。
