研究我国上市公司信息透明度与股票流动性的关系,对促进监管部门完善信息披露政策、加强监管和促进上市公司努力提高信息透明度具有积极意义.实证研究表明,上市公司信息透明度的提高可以增强股票的流动性,对减少投资者投机行为、持续稳定发展资本市场具有积极作用;深交所的信息披露考评工作是有成效的,上交所也应该披露此类信息披露考评结果,同时应该进一步完善信息披露考评体系,使考评结果更加科学化. 相似文献

随着我国股票市场的不断发展,股市的国际化、规范化程度正日益提高,我国股市的信息披露制度从无到有,已经形成一套初步的信息披露制度,对维护股市秩序、保护广大投资者利益发挥了积极作用。但是,我们看到上市公司的会计信息披露存在问题依然不少,会计信息披露所涉及的违规、违法事件仍时有发生,虚假会计信息的泛滥,严重扭曲了股票的价值,扰乱了资本市场秩序,损害了投资者的利益,极大地挫伤了股民的投资积极性。如果不加以严厉的打击和治理,我国的资本市场就难于有效健康地发展。一、上市公司会计信息披露中存在的问题1、信息披露不真实。股份公司为了公司股票上市需要、影响股票的市价、公司管理业绩评价或筹资的方便等目的,往往采取操纵行为,弄虚作假,披露不真实的会计信息。1999年中国证监会几度公告处罚出具虚假公告的上市公司,如东方锅炉为达到上市目的,虚增1992-1994年利润1500万元,在上市公告中做虚假披露;蓝田股份在股票发行申报材料中,虚增无形资产1100万元、虚增银行存款2770万元;四通高科虚假披露上市募集资金的使用情况、虚假披露1996年、1997年、1998年中期公司的资产、收入、利润的财务报告,类似此种情况屡见不鲜。2、信息披... 相似文献

Why firms and individuals reveal information is the subject of considerable theoretical research, but little empirical work has been possible due to a lack of suitable data. In this paper we examine why entrepreneurs selling business opportunities (franchisors) reveal information regarding potential profits (termed earnings claims). Empirical analysis shows that: first, contrary to theory, only a small percentage of franchisors claim; and, second, the franchisors that do claim have lower costs or are responding to competition. In particular, the prediction of theoretical models from economics that resource providers will not transact if information is not disclosed is not supported; resource providers can and do make significant investments even when entrepreneurs refuse to disclose information.

当前民生事件频发,公众越来越关注企业承担的社会责任,并要求其披露社会责任信息报告。企业在履行对社会的责任的同时也愿意披露相关信息,但由于信息不对称情况的存在,造成公司经营成本的增加。本文以非对称信息为前提,归纳总结了社会责任披露与公司经营成本之间的关系,并指出了我国企业社会责任信息披露的现状及存在的问题、分析其形成的原因。在此基础之上,积极探索完善责任信息披露的方法和途径,为企业合理披露责任信息以实现持续发展提供理论建议。 相似文献

This paper uses multivariate cointegration techniques to estimate a model of aggregate bank lending in the euro area. The model provides a quantitative benchmark for assessing conjunctural developments in loans to the area-wide private sector. Large and protracted deviations of realised loans from the paths implied by the model may reveal information about the emergence of financial imbalances as well as about the state of the economy, particularly about the strength of inflationary pressures. A specific application of the model shows that its error-correction term contains information on future changes in inflation over forecast horizons of relevance for monetary policy. 相似文献

Economic impact analysis can be used strategically by arts managers to provide information pertaining to making and justifying effective managerial and marketing decisions. The three aspects of economic impact analysis—direct, indirect and induced—reveal information such as arts participants' expenditure patterns, rationale for expenditure, relationships between participant demographics and expenditure, and amount of expenditure outside arts institutions. Arts managers can use the information and data to match product offerings of the institution with those of its participants; increase the participants' participation in, satisfaction with and loyalty to the institution; increase the stature and validity of the arts institution within the community; price the products of the arts institute; and increase community and financial support for arts institutions. This synergistic use of economic impact analysis information with marketing information is illustrated using a music institute in the USA. Copyright © 2003 Henry Stewart Publications 相似文献

In this paper, we propose a new mechanism able to explain the occurrence of credit crunches. Considering a credit market with an asymmetry of information between borrowers and lenders, we assume that borrowers have to pay a cost to reveal information on the quality of their project. They decide to be transparent if it is necessary for getting a loan or for paying a lower interest rate. Two types of competitive equilibria may exist: an opaque equilibrium in which all projects receive funding without revealing information; a transparent one in which only the best projects reveal information and receive funding. It is also possible to get multiple equilibria. Incorporating this microeconomic mechanism in an OLG model, the economy may experience fluctuations due to the change of regime, and indeterminacy may occur. 相似文献

We determine the conditions under which the seller in a first-price sealed-bid auction has an incentive to reveal his private information about the mean of bidders’ valuations in order to increase his expected revenue. With risk-neutral bidders, we show that the seller’s expected revenue is higher when information is revealed. However, when bidders are risk-averse, this result does not necessarily hold; it depends on the bidders’ risk-aversion level and on the number of bidders. 相似文献

A model of duopoly competition in nonlinear pricing when firms are imperfectly informed about consumer locations is analyzed.
A continuum of consumers purchase a variable amount of a product from one of two firms located at the endpoints of the market.
At the Nash equilibrium in quantity-outlay schedules, consumers buy the same quantities as they would from the same firm if
it were a monopolist facing the same informational asymmetries, but they receive greater surplus. Hence, no efficiency gains
result from competition. If consumers have the option to reveal their locations and have the firms deliver the goods, all
consumers choose to reveal their locations in equilibrium. Thus, the inefficiencies from information asymmetries may not arise
because firms can deliver the good to consumers. In contrast, with a monopoly seller, consumers have no incentives to reveal
their locations. 相似文献
