Labor Market Effects of Spatial Licensing Requirements: Evidence from CPA Mobility

We exploit the staggered introduction of CPA Mobility provisions in the United States to study the effects of spatial licensing requirements on the labor market for accounting professionals. Specifically, we examine whether the removal of licensing‐induced geographic barriers affects CPA wages and employment levels, as well as the pricing and quality of professional services. We find that, subsequent to the adoption of CPA Mobility provisions, wages of accounting professionals decrease, whereas employment levels are unaffected. The documented wage effect stems from smaller CPA firms, is more pronounced for CPAs holding senior positions, and persists over time. We also find that service prices decline and that this effect is concentrated in local CPA firms. Moreover, we document that the increased wage and price pressure is not associated with deteriorating service quality. Collectively, our results suggest that the removal of occupational licensing barriers has sizable effects on labor supply and service prices. Our findings inform the current regulatory debate on occupational licensing.

Internationalizing audit education

Audit education is typically offered only to accounting majors. We argue that auditing provides a way of thinking that could serve as a framework for an accounting curriculam. We describe two parts of a course content that could be incorporated into an existing auditing course or a begining accounting course. The first section emphasizes accountability; the second emphasizes the role of the auditor in the accountability process. The concepts are best taught within an international paradigm that permits examination of various institutional environments.     

The Relationship Among Ethical Climate,Job Satisfaction,Organizational Commitment,and External Auditor＇s Turnover Intention

This study attempts to examine the relationship among ethical climate, job satisfaction, organizational commitment, and turnover intention in the context of the Malaysian external auditor＇s work environment. The questionnaire is sent to a sample of external auditors from Malaysian Big Four （Klynveld Peat Marwick Goerdeler （KPMG）, Ernst and Young, Deloitte KassimChan, and PricewaterhouseCoopers （PwC）） main offices. There are 167 useable responses. The regression results have provided evidence that ethical climate is directly, significantly, and positively associated with job satisfaction. In contrast, ethical climate appeared not to be directly related with external auditor＇s turnover intention. Both job satisfaction and organizational commitment were identified as significant predictors in explaining turnover intention, since they had a significant and negative effect on external auditor＇s turnover intention. This study also implied that job satisfaction had a significant effect on organizational commitment. Furthermore, the findings revealed that organizational commitment partially mediated the relationship between job satisfaction and turnover intention. The results extend the literature on external auditor＇s turnover intention and provide insights for human resource management in accurately assessing employee＇s turnover intention in order to improve retention and reduce actual turnover particularly in audit firms.

Predicting credit card fraud with Sarbanes‐Oxley assessments and Fama‐French risk factors

This research developed and tested machine learning models to predict significant credit card fraud in corporate systems using Sarbanes‐Oxley (SOX) reports, news reports of breaches and Fama‐French risk factors (FF). Exploratory analysis found that SOX information predicted several types of security breaches, with the strongest performance in predicting credit card fraud. A systematic tuning of hyperparamters for a suite of machine learning models, starting with a random forest, an extremely‐randomized forest, a random grid of gradient boosting machines (GBMs), a random grid of deep neural nets, a fixed grid of general linear models where assembled into two trained stacked ensemble models optimized for F1 performance; an ensemble that contained all the models, and an ensemble containing just the best performing model from each algorithm class. Tuned GBMs performed best under all conditions. Without FF, models yielded an AUC of 99.3% and closeness of the training and validation matrices confirm that the model is robust. The most important predictors were firm specific, as would be expected, since control weaknesses vary at the firm level. Audit firm fees were the most important non‐firm‐specific predictors. Adding FF to the model rendered perfect prediction (100%) in the trained confusion matrix and AUC of 99.8%. The most important predictors of credit card fraud were the FF coefficient for the High book‐to‐market ratio Minus Low factor. The second most influential variable was the year of reporting, and third most important was the Fama‐French 3‐factor model R² – together these described most of the variance in credit card fraud occurrence. In all cases the four major SOX specific opinions rendered by auditors and the signed SOX report had little predictive influence.     

外部监督、股权激励与股权代理成本

基于股权代理成本角度,采用2010年中国沪深两市发行A股的非金融类上市公司截面数据,并运用最小二乘法和logistic二元逻辑回归模型,研究了外部监督、股权激励与股权代理成本之间的关系。研究发现,股权代理成本高的公司更加倾向于寻求有效的外部监督,聘请高质量的会计师事务所;股权激励并不能起到完善公司内部治理机制的作用,反而会提高股权代理成本;股权激励会提高公司对外部审计质量的要求。

基于电子取证技术的持续审计模型研究

缺乏系统的持续审计模型构造方法已成为制约当前计算机审计发展的瓶颈。在此背景下,以持续审计的工作原理为基础,本文提出一种基于电子取证技术的持续审计模型构造方法,它可以使持续审计更具有实时性和连续性。该模型通过实时监控异常行为的发生,一方面可以进行实时取证,对异常行为做详细记录,另一方面可以触发响应策略对不同强度的异常行为实施相应的响应。     

浅谈企业内部审计风险及其防范

内部审计是一项独立、客观的保证工作与咨询活动,目的是为组织增加价值并提高组织的运作效率。随着企业规模的扩大和业务活动繁杂,内部审计人员既要揭示会计准则遵循状况又“揭错查弊”,这意味着审计责任范围的逐渐扩大,同时也意味着内部审计风险的扩大,如何防范内部审计风险？本文分析了内部审计风险形成的客观、主观原因,提出了内部审计风险的防范对策。
