Audit report information content and the provision of non-audit services: Evidence from Spanish lending decisions

This study examines whether auditor economic independence affects the information content of going concern audit reports in the European setting. We conduct an experiment where 80 experienced Spanish loan officers from the second largest European commercial bank review a loan request under two lending scenarios: (1) a potential borrower receiving an unqualified but modified going concern opinion, and (2) a potential borrower receiving a qualified going concern opinion. Auditor economic independence, measured by the provision of non-audit services (NAS), is manipulated (absence vs. presence of significant NAS). We find that a qualified going concern audit report is interpreted as a primary warning signal (death penalty). However, the provision of NAS acts as a second order mechanism that only activates loan officers’ professional skepticism in the case of an unqualified but modified going concern report scenario. Therefore, we find evidence suggesting that the potential negative impact of a perceived lack of auditor independence depends on the nature of the audit report. Our findings have important implications for the European regulator, which is currently considering establishing an auditor independence regulation framework similar to that in the United States of America.     

The impact of MAS on perceived auditor independence-some evidence from Denmark

The Enron case has highlighted that the provision of management advisory services (MAS) can endanger auditor independence. Recently, a number of changes have not only been made to the relevant international and US regulations, but also to the Danish regulations in this area. Theoretical research explains the emergence of non-independence and demonstrates that the provision of MAS can decrease independence. According to the economic model of DeAngelo, the existence of client-specific quasi-rents impairs auditor independence. The provision of MAS increases quasi-rents and thus, is a threat to independence. Antle used an agency theoretical approach. Information asymmetries between auditor and client could lead to a moral hazard risk, i.e. the auditor could give up independence from client's management and accept payments for withholding detected errors and irregularities. The client's management could also use MAS to legally compensate the auditor for giving away independence.A large number of empirical studies have investigated the influence of MAS on the perceived independence of the auditor. Most of these studies were performed in English speaking countries and the majority found a negative impact. Sociological research reveals cultural differences between English speaking and Nordic countries, e.g. concerning the dimension ‘masculinity’. Thus, an empirical investigation of the impact of MAS on perceived auditor independence in Denmark is promising. It was found that shareholders, bank loan officers and journalists perceive a negative effect on auditor independence if MAS are provided. The recent liberalization in Denmark is inconsistent with this finding. Furthermore, it was shown that the type of MAS influences the degree to which auditor independence is perceived to be impaired. Thus, independence rules related to MAS should be differentiated. Additionally, the study ascertained that perceived auditor independence does not increase if MAS are provided by a separate department of the audit firm. An internal separation of the auditing and the consulting function within the same audit firm is not viewed as being beneficial in Denmark.

Client Importance and Audit Quality at the Individual Audit Partner,Office, and Firm Levels

We investigate whether audit partner level data provides a more powerful measure than office or firm level measures of client importance. We find that the likelihood of issuing a going-concern opinion (any and first-time) increases, and the absolute value of discretionary accruals decreases, in relation to the proportion of audit fees to the total audit fees received by audit partners from all their clients. We also find that the likelihood of issuing a going-concern opinion (any and first-time) increases, and the absolute value of discretionary accruals decreases, in relation to the proportion of non-audit services fees from a client to total non-audit service fees, and the proportion of total audit and non-audit service fees from a client to total fees from all their clients at the office and firm levels. Our findings provide evidence to regulators, audit clients, and stakeholders that audit partners do not succumb to pressure from economically more important clients as audit quality has a positive association with client importance.     

Trust and Understanding,Two Psychological Aspects of Randomized Response

This study examines two different Randomized Response methods to see whether they evoke sufficient understanding and trust, and ensure fewer evasive answers to socially sensitive questions. Two Randomized Response methods were employed by trained interviewers to study fraud: the Forced Response method, using dice, and Kuk's method, using playing cards. Respondents were selected from the files of the social security offices of three Dutch cities. A total of 334 respondents participated voluntarily in this study of two Randomized Response methods. Most respondents were known to have committed some form of fraud, and their answer on the Randomized Response question is validated with this information. The results indicate that subjects who have a better understanding of the Forced Response technique give more socially undesirable answers. The interviewer has a most important role establishing trust and understanding. Respondents who are less able to understand the instructions, e.g., have limited language abilities, develop less trust in the method.     

跨国银行海外经营动因研究——基于中国市场的实证分析

本文利用不同时期进入中国的各国银行的面板数据,分期讨论影响跨国银行进入中国市场的决定因素。研究发现,不同阶段影响跨国银行进入中国市场的因素不一致,但跟随客户动机是跨国银行进入中国的主要动因,中国经济高速成长产生的市场机会也对跨国银行的进入起到了积极的影响。1985～1996年样本期内,跨国银行进入动因区位优势假说得到了实证的支持;同时,不同阶段中国银行业对外开放政策及中国市场的风险因素也影响到跨国银行的进入速度。第二阶段的数据检验表明,中国经济高速增长对跨国银行进入中国市场产生了积极的影响。     

Do Big-Four affiliates earn audit fee premiums in emerging markets?

The paper investigates whether Big-Four affiliated (B4A) firms earn audit premiums in an emerging economy context, using Bangladesh as a case. The joint determination of audit and non-audit service fees is also examined using a sample of 122 companies listed in the Dhaka Stock Exchange. Our findings reveal that although the B4A firms do not generally earn a fee premium in Bangladesh, they charge higher audit fees for clients not purchasing non-audit services. This suggests that the B4A firms may actually lower audit fees to attract non-audit services, and cross subsidizes audit fees through non-audit-services fees. The lack of a B4A premium implies that there is lack of quality audit in emerging markets. We also document that audit and non-audit service fees are jointly determined in Bangladesh. Thus, we provide evidence of joint determination of audit and non-audit service fees in an emerging economy context.     

商业银行零售管理及目标客户流失概率预测研究

随着金融脱媒趋势逐渐凸显，商业银行以批发业务为主的盈利模式受到了极大的挑战。零售业务逐渐成为未来商业银行利润空间的主要组成部分。同时，商业银行越来越重视零售客户关系的管理与维护，并且逐渐意识到对目标客户行为数据进行分析的重要性。分析商业银行零售客户的流失因素及流失概率是客户行为分析的重要方面。研究表明，影响商业银行零售目标客户流失的因素较多，在诸多影响因素中，经COX模型的筛选，客户年龄、观察期内客户使用的产品数等因素对目标客户流失的解释作用是十分显著的。这些因素或正向或负向地作用于目标客户流失概率。
