会计师事务所合并与审计定价——基于2003—2009年十起合并案面板数据的研究

会计师事务所合并究竟是会提高还是会降低审计收费,取决于合并后事务所声誉及市场势力提升所带来的审计溢价与规模效应所导致的审计成本降低两方面孰者相对占优。文章以我国2003—2009年间十起事务所合并案为对象,利用其上市公司客户在事务所合并前后各2年的面板数据,检验了事务所合并对审计定价的影响。结果发现,事务所合并后,其审计收费显著提高。对所有事务所客户审计费用的横向比较也印证了上述结论。研究还发现,事务所合并后第一年审计收费的提升较第二年更为明显;就稳定客户数据而言,本土事务所之间合并对审计定价的影响不如涉及"四大"的合并显著;此外,新设合并与吸收合并对审计定价的影响没有显著差异。     

The Dividend Pricing Model: New Evidence from the Korean Housing Market

It is generally conceded that dividend pricing models are poor predictors of asset prices. This finding is sometimes attributed to excess volatility or to a dividend process manipulated by firm managers. In this paper, we present rather powerful panel tests of the dividend pricing relation using a unique data set in which dividends are set by market forces independent of managers' preferences. We rely on observations on the market for condominium dwellings in Korea—perhaps the only market in which information on dividends and prices is publicly and continuously available to consumers and investors. We extend the “dividend-price ratio model” to panels of housing returns and rents differentiated by type and location. We find broad support for the dividend pricing model during periods both before and after the Asian Financial Crisis of 1997–1998, suggesting that the market for housing assets in Korea has been remarkably efficient. Previous versions of this paper were presented at the Hong Kong-Singapore International Real Estate Research Symposium, August 2004, Hong Kong and the meeting of the Hong Kong Economic Association, January 2005.

The Provision of Non-audit Services and the Pricing of Audit Fees

There have been a number of studies examining audit fees and this research has covered various nations. Recent legislation in Norway requires a company to disclose information on the audit fee and the fees for non-audit services paid to its auditor. Using this data, models of audit fee structure are developed. As with other studies, the size of the company is a major determinant of the audit fee. Payments for non-audit services are positively and significantly associated with audit fees; this relationship is difficult to explain although it parallels some research in the United States. Overall, the models explain about 75 per cent of the variability in audit fees.     

An Examination of Audit Delay: Further Evidence from New Zealand

An important qualitative attribute of financial statements is timeliness. The recognition that the length of the audit may be the single most important determinant affecting the timing of earnings' announcements has motivated recent research on audit delay. The present study extends prior research by examining the multivariate relationship between a set of explanatory variables and audit delay for a large sample of New Zealand public companies. Further, the study includes two explanatory variables, company control (i.e. owner control versus manager control) and debt proportion, which have not previously been considered. The results indicate that both company size and sign of income significantly affect audit delay across the two years examined. Five other explanatory variables significantly affected audit delay for one of the two years examined. The adjusted R2s of the regression models, however, were relatively low. Additional analysis was also performed on each company control subsample. These results revealed that the effect of company size and income sign may be conditional upon company control. Implications from the results of the study for future research are discussed.     

审计市场结构与审计质量:来自中国证券市场的经验证据

本文以我国证券市场2004年~2005年的上市公司为研究样本,使用调整后的KS模型估计出的公司操纵性应计利润的绝对值作为审计质量的衡量指标,考察了审计市场结构和审计质量的关系。研究发现在控制了影响审计质量的相关变量之后,市场结构与审计质量存在以下关系:审计市场集中度与审计质量成正相关关系;市场的进入退出壁垒越高,审计质量越高;但审计师的行业专长不但没有提高审计质量,反而在一定程度上降低了审计质量;审计市场的强地域性与审计质量也没有明显的相关关系。     

Pricing Sovereign Credit Risk of Poland: Evidence from the CDS Market

We analyze the market assessment of sovereign credit risk using a reduced-form model to price the credit default swap (CDS) spreads, thus enabling us to derive values for the probability of default (PD) and loss given default (LGD) from the quotes of sovereign CDS contracts. We compare different specifications of the models allowing for both fixed and time-varying LGD, and we use these values to analyze the sovereign credit risk of Polish debt throughout the period of a global financial crisis. Our results suggest the presence of a low LGD and a relatively high PD during a recent financial crisis.     

Legal Liabilities, Audit Accuracy and the Market for Audit Services

In quality-differentiated audit markets with client-firms of unknown types, insider-managers of client firms strategically select auditors who respond to legal liabilities to decide their care level. In this signaling game, uninformed-investors use the audit report and the auditors' identity for firm valuation. The analysis shows that increased legal liability increases the auditor's effort and audit accuracy but reduces the demand for high quality auditing because, apart from the increased audit costs, the adverse selection benefit of the worse type reduces with increased accuracy. Furthermore, alternative legal regimes and damage allocation rules alter informational efficiency of the financial market.     

审计任期与审计质量:来自中国证券市场的经验证据

本文以中国证券市场上2000年至2002年期间获得标准无保留审计意见的上市公司为样本,使用经过一定调整后的截面Jones模型估计出的公司操纵性应计利润的绝对值作为审计质量的衡量指标,考察了会计师事务所审计任期与审计质量之间的关系。研究发现,在控制了事务所变更、事务所特征、行业成长性、公司规模、经营业绩、资产负债率、上市年龄以及样本所在年度后,审计任期与公司操纵性应计利润的绝对值呈正U型关系,即审计任期与审计质量呈倒U型关系。进一步分析发现,当审计任期小于一定年份(约6年)时,审计任期的增加对审计质量具有正面影响,而当审计任期超过一定年份(约6年)时,审计任期的增加对审计质量具有负面影响。     

Stock Market Volatility in an Emerging Market: Further Evidence from the Athens Stock Exchange

We investigate the time series properties of the daily and weekly returns from the Athens Stock Exchange (ASE) index for the years 1987 to 1997. We investigate whether important time-series characteristics have changed significantly over time. The Greek market has recently undergone major changes including complete capital flow liberalization, the implementation of computerized trading, as well as significant increases in market volume and capitalization; we thus contrast the 1987–90 and 1991–97 periods. Our findings suggest the dynamics of the ASE composite index returns have changed as the market has developed.     

中国上市公司初始审计的定价折扣考察——来自审计师变更的经验证据

初始审计的定价折扣具有重要的与审计独立性相关的公共政策含义。本文基于DeAngelo(1981)和Dye(1991)关于初始审计定价折扣的竞争性理论预期,利用2002——2004年我国审计市场的数据对初始审计的定价行为与特征进行了较为细致的实证考察。经验结果支持中国证监会关于审计费用的强制性公开披露政策,准租金和低价折扣引起的潜在的审计独立性问题会随着审计费用的公开披露而得到消除或减轻。本文还具有重要的监管含义:对审计师变更的监管应着重关注那些大型上市公司在小型会计师事务所之间进行变更的行为。     

Non-Segmented Equilibria Under Differential Taxation: Evidence from the Canadian Government Bond Market

This paper investigates tax effects in the Canadian governmentbond market during the period 1964—1986. Unlike previousstudies, we apply both statistical and nonstatistical teststoanalyze clientele effects and market equilibria. The resultsdivide the sample into two distinct periods of time, with theend of 1976 marking the division. We find that tax effects arealmost nonexistent in the Canadian government bond market beforethe end of 1976, but are predominant in the post-1976 period.Non-segmented market equilibria cannot be rejected before 1977,but are strongly rejected after 1976. In fact, segmented equilibriawith clientele effects in both quantities and prices characterizethe entire five year period from 1982 to 1986. These findingsare consistent with tax reforms, government deficit financingand interest rate fluctuations in Canada during our sample period.

审计委员会与审计质量——来自中国A股市场的经验证据

本文以中国2004年—2005年期间获得无保留审计意见的A股上市公司为研究样本,采用截面Jones模型估计出的公司操纵性应计利润(盈余管理)的绝对值作为审计质量的衡量指标,考察了审计委员会与审计质量之间的关系。研究发现,在控制了"会计师事务所规模"、"公司是否面临退市风险"、"审计意见是否带强调事项"、"公司经营活动现金流"、"公司盈余数量"、"年度"等指标后,设立审计委员会的公司的盈余管理绝对值显著比未设立审计委员会的公司小,这说明审计委员会能够显著的提高审计质量。进一步研究发现:审计委员会的成立时间越长,审计质量越高;审计委员会在2005年的作用比2004年更加显著。     

Derivative Pricing with Liquidity Risk: Theory and Evidence from the Credit Default Swap Market

We derive an equilibrium asset pricing model incorporating liquidity risk, derivatives, and short‐selling due to hedging of nontraded risk. We show that illiquid assets can have lower expected returns if the short‐sellers have more wealth, lower risk aversion, or shorter horizon. The pricing of liquidity risk is different for derivatives than for positive‐net‐supply assets, and depends on investors' net nontraded risk exposure. We estimate this model for the credit default swap market. We find strong evidence for an expected liquidity premium earned by the credit protection seller. The effect of liquidity risk is significant but economically small.     

投资者异质性与证券市场定价——理论模型与中国的经验证据

本文从投资者异质性的客观现实出发,通过对投资者二维视角的交叉分类与相关行为的探讨,提出了一种按交易特点与行为依据的新的分类方案,即将投资者分为套利交易者、价格预期交易者和量能变动交易者三类。在此基础上分别建立了各类投资者的需求函数,通过对证券市场供求函数的讨论,利用均衡分析方法构建了基于投资者异质性的证券市场定价模型,并以我国证券市场1999-2011年的月度数据为样本进行了实证分析。实证结果表明:我国证券市场价格主要由价格预期交易者的诱导性策略行为与量能变动交易者的羊群行为决定,套利交易者的套利行为对市场价格没有显著的影响,证券市场扩容也未对市场价格的形成产生系统性冲击。     

审计师选择与设立审计委员会的自选择问题——来自中国证券市场的经验证据

本文采用Heckman(1978)的二阶段回归方法,以2002-2006年我国证券市场上市公司为研究样本,在研究审计师选择的同时控制了设立审计委员会的自选择问题,并将公司设立审计委员会的实际情况与假设的相反情况进行对比,分析它们不同的审计师选择倾向,从而间接检验了审计委员会的治理效率。研究发现:自选择问题对审计师选择存在显著的影响。因此,拒绝了公司随机设立审计委员会的原假设;在控制自选择之后,回归方程中变量的斜率系数整体上存在显著差异;并且没有设立审计委员会的公司比设立审计委员会的公司更可能聘请四大会计师事务所。     

The Market for External Audit Services in the Public Sector: An Empirical Analysis of NHS Trusts

This study investigates the market for audit services in the UK National Health Service (NHS). The market has a number of interesting features, including the presence of the Audit Commission as a regulator, appointer and provider of audit services. Following a theoretical overview of audit pricing in the NHS, evidence is provided on the behaviour of private sector auditors in an environment where audit risk characteristics differ from the private sector. The research also investigates, for the first time in the public sector, the relationship between audit fees and non–audit (consultancy) fees. Comparisons are also drawn between audit fees in the public and private sectors in an analysis of audit fees by industry. Despite some key similarities, the study shows that a number of differences exist between private and public sector audit fee models. In particular, we find no evidence of Big 6 (or mid–tier) auditor premiums, but we do find a significant negative relationship between audit and consultancy fees providing support for the 'knowledge spill–over' hypothesis. In addition, the fees charged to trusts appear significantly lower than their private sector counterparts, despite trust auditors having additional duties to perform. Possible explanations for this finding are offered in the paper.     

审计失败与会计师事务所声誉损失:来自IPO审核的证据

本文分析了会计师事务所审计失败对其客户IPO审核拒绝率的影响。我们研究发现,会计师事务所审计失败会导致其声誉损失,其客户的IPO审核拒绝率将显著提高。发生审计失败后,不管事务所是否受到监管处罚,其客户的IPO审核拒绝率都会显著提高,但审计失败后受处罚的会计师事务所(受处罚所)的客户IPO审核拒绝率显著高于审计失败后未受处罚的会计师事务所(未受处罚所)的客户IPO审核拒绝率,即监管处罚对会计师事务所的声誉产生了更严重的后果。我们进一步发现,不同类型的会计师事务所,审计失败对其客户IPO审核拒绝率的影响不同。
