英语原文共 34 页 Does Customer Auditing Help Chinese Workers? Guojun He* and Jeffrey M. Perloff** February 2012 Abstract Auditing by downstream firms has limited effects on Chinese firmsrsquo; adherence to labor standards and other measures of blue collar workers well-being. Auditing does not affect the suppliersrsquo; blue-collar employeesrsquo; wages, probability of belonging to a union, or likelihood of working overtime. However, audited firms are more likely to provide rural migrant workers pensions, business medical insurance, and unemployment insurance. Introduction Does auditing by downstream firms affect how Chinese firms treat their workers? Using a large sample of firms from the National Bureau of Statistics of Chinarsquo;s Private Sector Survey of China, we investigate the relationship between customer auditing and Chinese blue-collar workersrsquo; welfare. When we examine the relationships between auditing and welfare measure
英语原文共 12 页 Audit risk and corporate governance: Italian auditorsrsquo; perception after the global financial crisis Chiara Demartini and Sara Trucco Abstract This paper aims at analysing the most relevant factors for auditors when they estimate audit risk of their client company, and charge the client for it. We did so, by asking partners of audit firms to rate their agreement on the relevance of a set of audit risk factors drawn from the literature. In order to investigate further, we analysed results after the 2007-2008 financial crisis, for new client firms. We ended up with a dynamic analysis of the factors auditors pay attention to when auditing a companyrsquo;s financial statement, by including the effect of a financial crisis in the auditing model. Therefore, this paper contributes to the auditing and corporate governance literature, by identifying those factors such as, among others, sector, effectiveness of internal control
英语原文共 7 页 Auditor industry specialization,board governance, and earnings management Jerry Sun Odette School of Business, University of Windsor, Windsor, Canada, and Guoping Liu Ted Rogers School of Management, Ryerson University, Toronto, Canada Abstract Purpose – The purpose of this study is to investigate the interaction effect of auditor industry specialization and board governance on earnings management. This study examines whether board independence is more or less effective in constraining earnings management for firms audited by industry specialists than for firms audited by non-specialists. Design/methodology/approach – The US data were collected from the RiskMetrics Directors database and the Compustat database. Regression analysis was used to test the research proposition. Findings – It was found that earnings management is more negatively associated with board independence for firms audited by industry
