This study examines the relationship between audit committee and board independence and auditor resignations. Independent audit committee and board members, who are concerned about incurring legal liability and harming their reputations, support the external auditors in accomplishing their assurance duties. We use a logit model to compare audit committee and board independence between two types of auditor switches: 190 auditor-initiated switches versus 190 matched client-initiated switches durin

This study examines whether audit report lags (ARLs) are influenced by auditor tenure and the provision of non‐audit services by the external auditor. Studying this association is important because ARLs are directly associated with audit efficiency and with the timeliness of companies' announcements of earnings. Our results show that both auditor tenure and non‐audit services are significantly associated with ARLs. With regard to auditor tenure, we find that ARLs decline as auditor tenure length

This study examines how the Private Securities Litigation Reform Act of 1995 (PSLRA) affects auditors' incentives to curtail earnings management by client managers. The most significant reform of PSLRA was the elimination of joint and several liability under which auditors and other parties could be named to lawsuits because of ‘deep pockets’ rather than culpability. While the elimination of joint and several liability provides significant relief to auditors from litigation, opponents of PSLRA a

Abstract This study examines whether multinational firms report earnings sooner than domestic firms. When compared with domestic firms, the reporting environment and business operations of multinational firms are significantly more complex. There is a greater amount of information asymmetry between managers and shareholders of multinational firms. Therefore, multinational firms potentially face higher monitoring and external financing costs. To reduce these costs, we conjecture that managers of

Although acoustic energy sources are an excellent alternative energy resource for harvesting, studies on harvesting such sources have been rarely investigated because of their lower energy density compared to other resources. For the purpose of efficient acoustic energy harvesting, this study presents a Helmholtz resonator with single-layer and multilayer piezoelectric composite cantilevers. A flexible PVDF piezoelectric composite cantilever is employed in this study due to the simple adjustment

This study examines the association between related-party transactions (RPTs, hereafter) and comparability of accounting information. We posit that comparability decreases with RPTs where much management discretion is likely to be involved in determining volume and terms. In addition, firms conducting RPTs are more likely to make accounting choices which make their accounting information less comparable to their industry peers to prevent government detection of illegal RPTs. Using a unique data-

Indium oxide (In 2 O 3 ) is a transparent wide-bandgap semiconductor suitable for use in the back-end-of-line-compatible channel layers of heterogeneous monolithic three-dimensional (M3D) devices. The structural, chemical, and electrical properties of In 2 O 3 films deposited by plasma-enhanced atomic layer deposition (PEALD) were examined using two different liquid-based precursors: (3-(dimethylamino)propyl)-dimethyl indium (DADI) and ( N, N -dimethylbutylamine)trimethylindium (DATI). DATI-deri

The Korean government requires listed firms to disclose the total number of employees engaged in the implementation of internal controls (hereafter, IC personnel) and the number of IC personnel in accounting, finance, information technology and systems departments, and other related functional areas. Using data unique to Korea, this study examines the effect of human resource investment in internal control on audit reporting lag (ARL). We employ quantitative and qualitative measures for the IC p

This paper presents a sensitivity-enhanced wireless passive LC pressure sensor for monitoring bladder pressure, which can be minimally invasive implanted in the bladder or integrated to a commercial urinary catheter and avoid battery lifetime problem. The proposed sensor design and the theoretical model are useful to increase the pressure sensitivity of a typical air-sealed capacitive pressure sensor, particularly having a flexible diaphragm. The test results of an in vitro evaluation of the pro

Utilizing unique data available only in Korea, we examine the association between investment in human resources and audit quality provided by audit firms. While human resources investment is important in improving audit quality, few studies have examined this association mainly because public data about human resources investment and financial statements of audit firms are unavailable. Using two proxies for audit quality (i.e. discretionary accruals and accounting conservatism), we provide evide

Abstract This article examines the influence of majority shareholder ownership on real earnings management. It investigates whether there is a conflict between or an alignment of majority and minority shareholders' interests. If majority shareholders' interests are aligned with those of minority shareholders, a greater majority shareholder ownership lowers real earnings management. On the other hand, if they are not aligned, majority shareholders' attempts to exploit minority shareholders will i

Purpose Using 5,055 sample firm-years in Korea between 2009 and 2013, this paper aims to examine the association between the characteristics of the internal audit and the number of external audit hours as a proxy for audit efficiency. Design/methodology/approach This study is motivated by the International Standard on Auditing No. 610: “Using the work of internal auditors”. This auditing standard guides external auditors in using the work of internal auditors to obtain audit evidence and consult
