The ethics of creative accounting

The term 'creative accounting' can be defined in a number ofways. Initially we will offer this definition: 'a processwhereby accountants use their knowledge of accounting rulesto manipulate the figures reported in the accounts of abusiness'.To investigate the ethical issues raised by creativeaccounting we will:- Explore some definitions of creative accounting.- Consider the various ways in which creative accounting can be undertaken.- Explore the range of reasons for a company's directors to engage in creative accounting.- Review the ethical issues that arise in creative accounting.- Report on surveys of auditors' perceptions of creative accounting in the UK, Spain and New Zealand.

Motivation, test scores and economic success

This paper argues that low-stakes test scores, available in surveys, may be partially determinedby test-taking motivation, which is associated with personality traits but not with cognitiveability. Therefore, such test score distributions may not be informative regarding cognitiveability distributions. Moreover, correlations, found in survey data, between high test scoresand economic success may be partially caused by favorable personality traits. To demonstratethese points, I use the coding speed test that was administered without incentives to NationalLongitudinal Survey of Youth 1979 (NLSY) participants. I suggest that due to its simplicityits scores may especially depend on individuals' test-taking motivation. I show that controllingfor conventional measures of cognitive skills, the coding speed scores are correlated with futureearnings of male NLSY participants. Moreover, the coding speed scores of highly motivated,though less educated, population (potential enlists to the armed forces) are higher than NLSYparticipants' scores. I then use controlled experiments to show that when no performance-basedincentives are provided, participants' characteristics, but not their cognitive skills, affect effortinvested in the coding speed test. Thus, participants with the same ability (measured by theirscores on an incentivized test) have significantly different scores on tests without performance-based incentives.

Creative accounting: Some ethical issues of macro- and micro-manipulation

This paper examines two principal categories of manipulative behaviour. The term'macro-manipulation' is used to describe the lobbying of regulators to persuadethem to produce regulation that is more favourable to the interests of preparers.'Micro-manipulation' describes the management of accounting figures to produce abiased view at the entity level. Both categories of manipulation can be viewed asattempts at creativity by financial statement preparers. The paper analyses twocases of manipulation which are considered in an ethical context. The paperconcludes that the manipulations described in it can be regarded as morallyreprehensible. They are not fair to users, they involve an unjust exercise ofpower, and they tend to weaken the authority of accounting regulators.

The struggle against creative accounting: Is "true and fair view" part of the problem or part of the solution?

Creative accounting is a growing issue of interest in Spain. In this article we argue that the concept true and fair view can limit or promote the use of creative accounting depending upon its interpretation. We review the range of meanings that true and fair view can take at an international level and compare the experience of the United Kingdom with the Australian one by analysing the use of true and fair view to limit creative accounting. Finally, we suggest lines of action to be considered by the Spanish accounting standards-setting institutions.

Biplots of fuzzy coded data

A biplot, which is the multivariate generalization of the two-variable scatterplot, can be used to visualize the results of many multivariate techniques, especially those that are based on the singular value decomposition. We consider data sets consisting of continuous-scale measurements, their fuzzy coding and the biplots that visualize them, using a fuzzy version of multiple correspondence analysis. Of special interest is the way quality of fit of the biplot is measured, since it is well-known that regular (i.e., crisp) multiple correspondence analysis seriously under-estimates this measure. We show how the results of fuzzy multiple correspondence analysis can be defuzzified to obtain estimated values of the original data, and prove that this implies an orthogonal decomposition of variance. This permits a measure of fit to be calculated in the familiar form of a percentage of explained variance, which is directly comparable to the corresponding fit measure used in principal component analysis of the original data. The approach is motivated initially by its application to a simulated data set, showing how the fuzzy approach can lead to diagnosing nonlinear relationships, and finally it is applied to a real set of meteorological data.

Ethics and creative accounting: Some empirical evidence on accounting for intangibles in Spain

Recent research shows that financial reports are losing relevance. Mainly thisis due to the growing strategic importance of intangible assets in theperformance of a company. A possible solution is to modify accounting standardsso that statements include more self-generated intangible assets, taking intoaccount with their inherent risk and difficulty of valuation. We surveyed loanofficers who were asked to assess the credit-worthiness of a hypotheticalcompany. The only information given was a simplified version of financialstatements. Half the group got statements where research and development costshad been capitalized. The other half got statements in which these costs hadbeen treated as an expense. The findings show that capitalization wassignificantly more likely to attract a positive response to a loan request. Thepaper raises the question of whether accounting for intangibles might providemanagers with one more creative accounting technique and, in consequence, itsethical implications.

Worst-case bounds for the logarithmic loss of predictors

We investigate on-line prediction of individual sequences. Given a class of predictors, the goal is to predict as well as the best predictor in the class, where the loss is measured by the self information (logarithmic) loss function. The excess loss (regret) is closely related to the redundancy of the associated lossless universal code. Using Shtarkov's theorem and tools from empirical process theory, we prove a general upper bound on the best possible (minimax) regret. The bound depends on certain metric properties of the class of predictors. We apply the bound to both parametric and nonparametric classes ofpredictors. Finally, we point out a suboptimal behavior of the popular Bayesian weighted average algorithm.

The ethics of creative accounting: Some Spanish evidence

'Creative accounting' involves accountants in making accounting policy choices or manipulating transactions in such a way as to give the impression in the accounts that they prefer. While regarded as unethical by most observers, a defence of creative accounting can be based on the ability of the users of accounts to identify bias in accounting policy choices and make appropriate adjustments.In this paper we take the example of the Barcelona Football Club where the club management made three key accounting policy choices that presented a favourable position, and a supporters' club presented an alternative report choosing three alternative accounting policies that presented an unfavourable position. We presented each of these financial reports to one of two groups of Spanish bank loan offices, with supporting notes making the impact of the accounting policy choices clear. We found that the more favourable set of accounts was significantly more likely to attract a positive response to a loan request.This result undermines the defence for creative accounting, based on the ability of users to identify manipulation.

Creative accounting: Nature, incidence and ethical issues

This paper explores the nature and incidence of creative accounting practiceswithin the context of ethical considerations.It explores several definitionsof creative accounting and the potential and the range of reasons for acompany's directors to engage in creative accounting. Later the paperconsiders the various ways in which creative accounting can be undertaken andsummarizes some empirical research on the nature and incidence of creativeaccounting. The ethical dimension of creative accounting is discussed, drawingevidence from several empirical studies. The paper concludes with the analysisof possible solutions for the creative accounting problem.

Nota al artículo "El sistema de las Creative commons"

Después de leer el artículo "El sistema de las Creative Commons" de Marco Marandola1, me gustaría presentar de manera más completa el proyecto de las licencias de Creative commons. Actualmente las palabras copyleft, copyright, open access, creative commons, procomún, se utilizan mucho pero a veces se mezclan conceptos y se informa de manera errónea. Agradezco a los editores la posibilidad de escribir esta nota que personalmente considero de rectificación.

Quality coding by neural populations in the early olfactory pathway: analysis using information theory

In this article, we analyze the ability of the early olfactory system to detect and discriminate different odors by means of information theory measurements applied to olfactory bulb activity images. We have studied the role that the diversity and number of receptor neuron types play in encoding chemical information. Our results show that the olfactory receptors of the biological system are low correlated and present good coverage of the input space. The coding capacity of ensembles of olfactory receptors with the same receptive range is maximized when the receptors cover half of the odor input space - a configuration that corresponds to receptors that are not particularly selective. However, the ensemble's performance slightly increases when mixing uncorrelated receptors of different receptive ranges. Our results confirm that the low correlation between sensors could be more significant than the sensor selectivity for general purpose chemo-sensory systems, whether these are biological or biomimetic.

Design of Optical Systems With Extended Depth of Field: an Educational Approach to Wavefront Coding Techniques

A practical activity designed to introduce wavefront coding techniques as a method to extend the depth of field in optical systems is presented. The activity is suitable for advanced undergraduate students since it combines different topics in optical engineering such as optical system design, aberration theory, Fourier optics, and digital image processing. This paper provides the theoretical background and technical information for performing the experiment. The proposed activity requires students able to develop a wide range of skills since they are expected to deal with optical components, including spatial light modulators, and develop scripts to perform some calculations.

Les llicències de Creative Commons a l'Estat espanyol

[eng] The Creative Commons project in Spain has its beginnings in early 2003, but until one year ago it was not possible to access licenses adapted to Spanish legislation on intellectual property. In addition to this effort of adaptation, other activities have been carried out -centred especially on the dissemination and explanation of the licensing system- and the level of acceptance has been quite positive. This article covers the history of the project and provides an explanation of the licenses and a description of some of the initiatives that this legal system is carrying out.

Las licencias Creative Commons en el Estado Español

Hace un par de años poca gente conocía las licencias Creative Commons, pero actualmente este término empieza a ser asociado a un estándar de licencias para obras digitales libres en la red, de la misma manera que las licencias del proyecto GNU (GPL, LGPL)2 se asocian a un estándar para el software libre.

Noves alternatives per gestionar els drets d'autoria en la difusió de continguts. Les llicències de Creative Commons

Les llicències de Creative Commons són una alternativa a la gestió tradicional dels drets d'autor que s'ha estès ràpidament gràcies a Internet en els seus cinc anys d'existència. L'aparició d'aquesta nova eina legal ha obert un debat sobre els models de difusió de qualsevol contingut i, en definitiva, del coneixement que ha obligat a replantejaments no tan sols entre els autors i els creadors sinó també entre institucions i administracions. En aquest llibre es presenta el model que proposa Creative Commons per facilitar la difusió i l'accés als continguts de qualsevol persona, tot respectant-ne els drets d'autor.
