Impact of Auditor Report Changes on Financial Reporting Quality and Audit Costs: Evidence from the United Kingdom

While substantial revisions to auditor reporting requirements are being implemented internationally, the impact of these reforms on financial reporting quality is unknown. We exploit the United Kingdom's recent auditor reporting changes and find that the United Kingdom's new reporting regime is associated with an improvement in financial reporting quality as proxied by significant decreases in absolute abnormal accruals and the propensity to just meet or beat analyst forecasts, and a significant increase in earnings response coefficients. As for audit costs, we do not find a significant change in audit fees or audit delay surrounding the implementation of the new reporting regime. Taken together, the results of this study suggest that new auditor reporting requirements are associated with a significant improvement in financial reporting quality without detecting a significant increase in audit costs.

数字经济对区域经济高质量发展的影响研究

推动数字经济发展,是我国在当下推动经济转型,促进高质量发展的重要战略。本文基于2012~2019年省级面板数据,构建双向固定效应模型,运用基准回归、异质性检验和分位数回归的方法进行实证研究发现,数字经济助推经济高质量发展的同时还存在地区差异,对西部影响最大,中部影响最小,而数字经济的发展水平又受到产业结构、技术创新等因素影响。因此,本文针对不同地区差异分别提出建议,从而促进持续更新发展理念,以创新驱动发展,优化产业结构为数字经济提供良好环境,以期推动数字经济建设发展。     

Minimal Hellinger martingale measures of order <Emphasis Type="Italic">q</Emphasis>

This paper proposes an extension of the minimal Hellinger martingale measure (MHM hereafter) concept to any order q≠1 and to the general semimartingale framework. This extension allows us to provide a unified formulation for many optimal martingale measures, including the minimal martingale measure of Föllmer and Schweizer (here q=2). Under some mild conditions of integrability and the absence of arbitrage, we show the existence of the MHM measure of order q and describe it explicitly in terms of pointwise equations in ? ^d . Applications to the maximization of expected power utility at stopping times are given. We prove that, for an agent to be indifferent with respect to the liquidation time of her assets (which is the market’s exit time, supposed to be a stopping time, not any general random time), she is forced to consider a habit formation utility function instead of the original utility, or equivalently she is forced to consider a time-separable preference with a stochastic discount factor.     

限售股权定价的实证检验

我国上市公司的非流通股权实质为限售股权,股权分置改革改变了限售期的不确定性.通过对2004～2006年5月间326笔我国上市公司限售股权转让信息的研究发现:限售股股东向流通股股东支付对价是有理论和实证依据的,股权分置改革有利于国有资产保值增值.公司净资产、控制权收益以及公司流通股比例与限售股定价正相关.流动性约束与限售股定价负相关.受让方为非国有性质时,限售股转让相对价较低.股权转让方式、公司盈利能力等财务指标对限售股定价有一定影响.     

股票市场全收益率研究

中国股市发展中特有的股权分置结构决定了研究股市收益率问题的复杂性.本文提出用全收益率的标准来衡量中国股市的整体收益率,认为在股权分置及其逐步解决的过程中,研究股市全收益率具有重要的意义,也是讨论股市其它问题的理论基础.随着股权分置改革渐进式地推进,中国股市各类股权所有者的收益分布会发生显著的结构性变化.从长期看,股权分置改革能使投资股东和原始股东的收益函数趋于一致,有助于实现整体收益的最大化.     

企业纵向战略联盟动因:一个行业层面的分析

本文以我国22个行业中407家公司为样本,从行业层面对企业纵向战略联盟组建的动因进行了分析.结果表明,行业的成长性对纵向战略联盟的组建显著正相关,行业资本密度、进入壁垒则对纵向战略联盟的组建显著负相关.实证结果显示,行业盈利水平、成本压力与纵向战略联盟的组建影响不大.
