货币政策透明度的趋势、制度安排和宏观经济环境

近年来,透明度已经成为货币政策主要的特征之一,提高货币政策的透明度正在演变为一个国际趋势。根据Geraats(2009)使用Dicer和Eichengreen(2009)收集的数据测算的E-G指数,发现世界范围内货币政策的透明度已经取得了显著提高,但实践中呈现出执行较高行政透明度和经济透明度,而实行较低程序透明度和政策透明度的变化趋势;同时,还讨论了与透明度变化趋势相适应的制度安排及宏观经济环境。     

潜在错报风险、信息透明度与审计定价——基于中国证券市场的经验数据

本文选取了2002年至2003年在深圳证券交易所上市的779家公司作为研究样本,研究了潜在错报风险、信息透明度与审计定价的关系。研究发现,对于存在担保的公司,审计收费显著更高,而信息披露透明高的公司,则审计收费显著更低。这一研究结果表明,潜在错报风险高的公司,审计收费更高,注册会计师根据公司潜在风险的高低,收取了风险溢价。     

审计委员会透明度与供应商/客户关系型交易

关系型交易的隐蔽性决定了公开信息披露的不透明。利用2013年上交所强制要求审计委员会披露履职信息的准自然实验,构建双重差分模型,考察提高审计委员会透明度是否以及如何影响上市公司与供应商/客户之间的关系型交易。研究发现,提高审计委员会透明度在短期内对供应商/客户关系型交易有促进作用,这可能与政策实施传递的可置信承诺有关,信息使用者更加信任企业的信息披露,但长期内这一促进作用有所减弱。进一步验证信任机制的作用发现,只有当企业位于法律环境较好、社会信任度较高的地区时,提高审计委员会透明度才有利于开展此类关系型交易。此外,审计委员会透明度提高通过促进供应链关系型交易缓解了企业融资约束。上述结论丰富了关系型交易在公司信息环境层面影响因素的研究,并为监管部门评估审计委员会改革实施效果提供了经验证据支持。     

The Sarbanes-Oxley Act Will Change the Governance of Non Profit Organizations

As a public director of a NASDAQ stock exchange listed public corporation, I have seen how quickly the reforms in corporate governance imposed by the Sarbanes-Oxley Act have changed procedures and policies in public corporations. In areas such as transparency of financial records and other financial matters including compensation of top executives and conflict of interest policies affecting both corporate boards of directors and employees of the corporation the reforms of this new federal law have quickly changed corporate practices in many corporations. Many persons who have studied this new law believe that these changes will benefit the public, shareholders, employees, and other stakeholders in the modern corporation by increasing the reputation of these organizations for integrity and transparency. Stock exchanges such as NASDAQ and the New York Stock Exchange now require all listed companies to have (after a transition time) a majority of independent directors on their boards of directors. Only independent directors may serve on the audit, nominating and compensation committees of boards in most cases. Some exceptions are made to these rules for foreign and domestic issues of companies where a majority of the voting power is held by one person. According to Morrison & Foster LLP, Corporate Board Advisory March , 2004, NASDAQ requires that the board of directors of a listed company determine that an independent director does not have a relationship that would “interfere with the exercise of independent judgment” in carrying out the responsibilities of a director. Donald Grunewald served as President of Mercy College from 1972 to 1984. He has served as a member of the board of trustees of several colleges and proprietary educational institutions and on the boards of other charitable institutions. Currently he is a member of the Board of Directors of EVCI Career Colleges, Inc., a NASDAQ listed corporation.

以“数”谋“盈”：企业数字化转型对盈余持续性的影响研究

以2007—2021年沪深A股上市公司为研究样本,基于企业数字化转型的“治理效应”“信息效应”和“融资效应”,实证检验企业数字化转型对盈余持续性的影响及作用机制。研究发现,企业数字化转型可显著提高盈余持续性,其作用机制在于抑制真实盈余管理、提高信息透明度和缓解融资约束。从异质性视角来看,“底层技术运用”和“技术实践应用”均可显著提高盈余持续性;在非国有企业、成长性低的企业中,企业数字化转型对盈余持续性的影响更加显著。企业应该坚定实施数字化转型的信心,增强实施数字化转型的动力,以谋求持续稳定的收益。
