Nonaudit services provided by incumbent auditors and earnings management: Evidence of auditor independence from an EU country
2011
ABSTRACTThis paper examines whether the joint provision of audit and non-audit services undermines auditor independence by testing for an association between the provision of consulting services and auditor independence measured by discretionary accruals. For the most part, previous literature has studied the issue in countries with an Anglo-American business environment. This study analyzes the possible impairment of auditor independence in the context of a continental European Union country (Spain). A cross-sectional regression is estimated to test the relationship between non-audit fees and reporting quality. Based on publicly available information for Spanish listed companies, the evide…
Audit quality and the going-concern decision-making process: Spanish evidence
2004
In this study, we attempt empirically to investigate the relationship between audit quality and the probability that a financially distressed company would receive a going-concern opinion. Auditor decision-making in the presence of going-concern uncertainties may be characterized as a two-stage process. The first stage is the identification of a potential going-concern problem and the second stage is to determine whether the particular company should receive a qualified going-concern opinion. A sample of 1,199 non-financial Spanish company-years has been obtained from the database issued by the Stock Exchange National Commission for the fiscal years ending between December 1991 and December…
An Empirical Analysis of the Determinants of Perceived Inequality
2017
Perception of inequality is important for the analysis of individuals' motivations and decisions and for policy assessment. Despite the broad range of analytic gains that it grants, our knowledge about measurement and determinants of perception of inequality is still limited, since it is intrinsically unobservable, multidimensional, and essentially contested. Using a novel econometric approach, we study how observable individual characteristics affect the joint distribution of a set of indicators of perceived inequality in specific domains. Using data from the International Social Survey Programme, we shed light on the associations among these indicators and how they are affected by covaria…
Testing for Asymmetric Information in Insurance Markets: A Multivariate Ordered Regression Approach
2016
The positive correlation (PC) test is the standard procedure used in the empirical literature to detect the existence of asymmetric information in insurance markets. This article describes a new tool to implement an extension of the PC test based on a new family of regression models, the multivariate ordered logit, designed to study how the joint distribution of two or more ordered response variables depends on exogenous covariates. We present an application of our proposed extension of the PC test to the Medigap health insurance market in the United States. Results reveal that the risk–coverage association is not homogeneous across coverage and risk categories, and depends on individual so…
The Invariant Distribution of Wealth and Employment Status in a Small Open Economy with Precautionary Savings
2019
Abstract We study optimal savings in continuous time with exogenous transitions between employment and unemployment as the only source of uncertainty in a small open economy. We prove the existence of an optimal consumption path. We exploit that the dynamics of consumption and wealth between jumps can be expressed as a Fuchsian system. We derive conditions under which an invariant joint distribution for the state variables , i.e., wealth and labour market status, exists and is unique. We also provide conditions under which the distribution of these variables converges to the invariant distribution. Our analysis relies on the notion of T-processes and applies results on the stability of Mark…
Beyond the audit expectations gap
1992
In seeking to encourage a broader, European dimension to research on auditing and audit expectations, this paper examines the recent history of auditing and its regulation in Spain within the context of international developments in the accounting profession. The more expansive role being assigned to the audit function in Spain following the implementation of the Fourth and Eighth European Company Law Directives is generally viewed by Spanish writers as a progressive step, with largely positive effects. Such views stand in some contrast to the history of auditing in Britain, where the prevalence of an ‘audit expectations gap’ suggests a rather more problematic state of affairs. In exploring…
"Dynamical" interactions and gauge invariance
2009
Appreciating the classical understanding of the elementary particle the "dynamical" Poincare algebra is developed. It is shown that the "dynamical" Poincare algebra and the equations of motion of particles with arbitrary spin are gauge invariant and that gauge invariance and relativistic invariance stand on equal footings. A "dynamical" non-minimal interaction is constructed explicitly and the Rarita-Schwinger equation is considered in the framework of this "dynamical" interaction.
On the repeatability of the EMI for the monitoring of bonded joints
2015
We study the feasibility and the repeatability of the electromechanical impedance (EMI) method for the health monitoring of lightweight bonded joints. The EMI technique exploits the coupling between the displacement field and the potential field of a piezoelectric material, by attaching or embedding a piezoelectric transducer to the structure to be monitored. The sensor is excited by an external voltage and the electrical admittance which is the ratio between the electric current and the applied voltage is measured as it depends on the mechanical coupling between the transducer and the host structure. Owing to this interaction, the admittance may represent a signature for the health of the …
Electromechanical impedance method for the health monitoring of bonded joints: Numerical modelling and experimental validation
2014
The electromechanical impedance (EMI) method is one of the many nondestructive evaluation approaches proposed for the health monitoring of aerospace, civil, and mechanical structures. The method consists of attaching or embedding one or more wafer-type piezoelectric transducers (PZTs) to the system of interest, the host structure, and measuring certain electrical characteristics of the transducers. As these characteristics are also related to the impedance of the host structure, they can be used to infer the mechanical properties of the monitored structure. In the study presented in this paper, we utilize the EMI to monitor the quality of adhesively bonded joints. A finite element formulati…
Polyamide-Based Fibers Containing Microwave-Exfoliated Graphite Nanoplatelets
2016
Exfoliated Graphite NanoPlatelets (GNP) have been obtained from Graphite Intercalation Compounds (GIC) subjected to thermal and microwave treatments. Accurate morphological and structural characterization of obtained GNP, performed to compare the degree of exfoliation, show that microwave-treated GNP, exhibit well-exfoliated structure, without any reduction in dimensions compared with the native GIC, differently to the thermal-treated ones. Microwave-treated GNP have been introduced in polyamide (PA) through melt-mixing to obtain nanocomposite that has been subjected to elongational flow, with the aim to improve the nanofiller dispersion and induce GNP orientation along the fiber direction.…
