Fair value versus historic cost-valuation for biological assets: Implications for the quality of financial information

[spa] Este trabajo realiza un estudio empírico sobre los efectos, que se señalan en las discusiones teóricas, de la utilización del valor razonable (VR) frente al coste histórico (CH), utilizando dos muestras de explotaciones agrícolas, una de las cuales valora sus activos biológicos a CH y la otra a VR. No se encontraron diferencias significativas en los beneficios e ingresos entre ambas muestras, ni siquiera en sus volatilidades. Tampoco se encontraron diferencias significativas en rentabilidad, manipulación contable, ni en el poder de ambos criterios de valoración para predecir los flujos de tesorería. Por el contrario, la mayor parte de los tests realizados revelan un mayor poder de los beneficios calculados bajo el VR para la predicción de los beneficios futuros, respecto de cuando son calculados bajo el CH. El estudio proporciona también evidencia empírica de prácticas contables defectuosas de CH en el sector agrícola, concluyendo que el VR puede representar un criterio de valoración interesante para un sector, como el agrícola, caracterizado por el predominio de pequeñas explotaciones familiares.

Porte da auditoria e manipulação da informação contábil: uma revisão sistemática da literatura

Este estudo examina a relação entre o porte da empresa de auditoria e a manipulação da informação contábil. Consistente com a literatura, o porte de auditoria tem sido utilizado como proxy de qualidade do serviço, e classificado como auditoria Big 6 e não-Big 6, sendo quanto maior o porte, maior a qualidade. A pesquisa abrangeu os estudos que utilizam acumulações discricionárias na estimação da manipulação da informação contábil. Por meio de uma revisão sistemática da literária, foram selecionadas 14 pesquisas empíricas, abrangendo Estados Unidos, Europa e Ásia. Com base na análise dos seus aspectos substantivos e metodológicos, a conclusão é que a magnitude da manipulação da informação contábil não é uniforme nos países estudados sugerindo que os ambientes cultural, institucional e legal podem influenciar a capacidade da auditoria em mitigar a ação discricionária dos gestores.

Earnings management nas instituições particulares de solidariedade social

A manipulação contabilística constitui-se como uma problemática atual, relatada sob os mais diversos contextos. Este estudo descritivo pretende verificar a existência de Earnings Management no contexto das Instituições Particulares de Solidariedade Social (IPSS) e averiguar as razões (motivações) que levam a estas práticas. A amostra para este estudo é constituída por 14 instituições portuguesas, num total de 58 observações situadas entre os anos 2009 e 2014. Para a análise dos dados foi utilizada uma abordagem quantitativa, primeiramente através de estatística descritiva e correlacional. Para testar a existência de Earnings Management utilizou-se um modelo baseado no estudo de accruals agregados (Modelo de Jones - 1991) e um modelo complementar baseado na distribuição de frequência de resultados (Burgstahler e Dichev -1997). Os resultados permitem inferir a existência destas práticas neste setor e as motivações estarão relacionadas com a rendibilidade das instituições.

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.

Manipulation of earnings reports in Spain - some evidence

Accounting regulation is a highly topical issue for listed companies in Europe. From 1 January 2005 all companies listed in the EU member states are required to produce financial reports compliant with international accounting standards. Financial reports will be comparable with each other only if full compliance with the international standards can be ensured. Historically, however, an enduring weakness of the international standard-setting regime has been its inability to enforce compliance with its standards. There is a danger that implementation and compliance will be variable across the adopting countries, and that deeply ingrained national reporting practices will persist. The purpose of this paper is to examine some distinctive elements of Spanish financial reporting practices. Spanish financial reporting by major companies demonstrates a tendency towards quite overt manipulation of the earnings figures. The research reported in the paper firstly identifies four common earnings manipulation practices, and then proceeds to examine their incidence in the financial statements of the IBEX-35 companies over a three year period.

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.

Accounting for management costs in sensitivity analyses of matrix population models

Traditional sensitivity and elasticity analyses of matrix population models have been used to p inform management decisions, but they ignore the economic costs of manipulating vital rates. For exam le, the growth rate of a population is often most sensitive to changes in adult survival rate, but this does not mean that increasing that rate is the best option for managing the population because it may be much more expensive than other options. To explore how managers should optimize their manipulation of vital rates, we incorporated the cost of changing those rates into matrix population models. We derived analytic expressions for locations in parameter space where managers should shift between management of fecundity and survival, for the balance between fecundity and survival management at those boundaries, and for the allocation of management resources to sustain that optimal balance. For simple matrices, the optimal budget allocation can often be expressed as simple functions of vital rates and the relative costs of changing them. We applied our method to management of the Helmeted Honeyeater (Lichenostomus melanops cassidix; an endangered Australian bird) and the koala (Phascolarctos cinereus) as examples. Our method showed that cost-efficient management of the Helmeted Honeyeater should focus on increasing fecundity via nest protection, whereas optimal koala management should focus on manipulating both fecundity and survival simultaneously, These findings are contrary to the cost-negligent recommendations of elasticity analysis, which would suggest focusing on managing survival in both cases. A further investigation of Helmeted Honeyeater management options, based on an individual-based model incorporating density dependence, spatial structure, and environmental stochasticity, confirmed that fecundity management was the most cost-effective strategy. Our results demonstrate that decisions that ignore economic factors will reduce management efficiency.

An examination of accounting and auditing issues related to strategic environmental initiatives

Although corporate environmental accountability is receiving unprecedented attention in the United States from policy makers, the capital market, and the public at large, extant research is limited in its examination of the implications of strategic corporate environmental initiatives on accounting and auditing. The purpose of my dissertation is to address these implications by examining the association between firm environmental initiatives and audit fees, capital expenditures, and earnings quality using multivariate regression analysis. I find that firms engaged in more strategic environmental initiatives tend to have significantly higher audit fees and capital expenditures, and significantly lower levels of earnings manipulation measured using discretionary accruals. These results support the notion that auditors do recognize the importance of environmental initiatives when conducting the year-end financial statement audit, an idea that positively reflects upon the auditor’s monitoring role. The results also demonstrate the increased amount of capital resources required to participate in strategic environmental initiatives, an anecdotal notion that had yet to be empirically supported. This empirical support provides valuable insights on how environmental initiatives materially impact corporate financial statements. Finally, my results extend the extant literature by demonstrating that the superior financial performance reported by environmentally active firms is less likely driven by earnings manipulation by management, and by implication, more likely a result of real economic gains. Taken together, my dissertation establishes a strong and timely foundation for current and future research to explore corporate environmental initiatives in the United States and globally, a topic increasingly gaining momentum in today’s more eco-conscious world.^

Företags potentiella manipulation av tillväxttakt i goodwillnedskrivningstestet : En kvantitativ studie av svenska och finska börsnoterade företag

Bakgrund och problem: I och med den nya standarden IAS 36 ska företagen göra uppskattningar angående den långsiktiga tillväxttakten i goodwillnedskrivningstestet. Detta innebär en möjlighet att manipulera tillväxttakten för att på så vis undvika eller framkalla nedskrivning av goodwill. Problemformulering: Hur påverkar utvalda variabler företags potentiella manipulation av angiven tillväxttakt? Syfte: Syftet med studien är att bidra med förklaringar till vad som påverkar att företag redovisar för höga respektive för låga tillväxttakter i goodwillnedskrivningstestet. Metod: Denna studie bygger på en kvantitativ metod där urvalet består av samtliga svenska och finska börsnoterade företag med redovisad goodwill. Utifrån existerade kunskap formuleras fyra hypoteser som testas mot empirin. Resultat och slutsats: Resultatet av denna studie visar inga signifikanta samband mellan den beroende variabeln manipulation och de oberoende variablerna storlek, skuldsättningsgrad, bransch och redovisningstillsyn. Den deskriptiva statistiken visar att i stort sett hälften av företagen manipulerar tillväxttakten.

Manipulation of quantum state transfer in cold Rydberg atom collisions

We investigate the role of the dc Stark effect in multilevel pairwise interactions between cold Rydberg atoms. We have observed the decay of nD + nD quasi-molecules by detecting the products in the (n + 2) P state after pulsed excitation for 29 <= n <= 41. The decay rate can be manipulated with a dc electric field and requires a consideration of the multilevel nature of the process to explain the observations. The time dependence of the (n + 2) P signal is found to support a time-dependent picture of the dynamics.

Manipulation of rest period length induces different causes of fatigue in vertical jumping

The aim of this study was to directly compare the causes of fatigue after a short- and a long-rest interval between consecutive stretch-shortening cycle exercises. Eleven healthy males jumped with different resting period lengths (short = 6.1 +/- 1 s, long = 8.6 +/- 0.9 s), performing countermovement jumps at 95% of their maximal jump height until they were unable to sustain the target height. After short- and long-rest, the maximal voluntary isometric contraction knee extension torque decreased (-7%; p = 0.04), comparing to values obtained before exercise protocols. No change was seen from pre- to post-exercise, for either short- or long-rest, in biceps femoris coactivation (-1%; p = 0.95), peak-to-peak amplitude (1%; p = 0.95) and duration (-8%; p = 0.92) of the compound muscle action potential of the vastus lateralis. Evoked peak twitch torque reduced after both exercise protocols (short = -26%, long = -32%; p = 0.003) indicating peripheral fatigue. However, central fatigue occurred only after short-rest evidenced by a reduction in voluntary activation of the quadriceps muscle (-14%; p = 0.013) measured using the interpolated twitch technique. In conclusion, after Stretch-shortening cycle exercise using short rest period length, the cause of fatigue was central and peripheral, while after using long rest period length, the cause of fatigue was peripheral.

Monocular vision and increased distance reducing the effects of visual manipulation on body sway

The goal of this study was to examine the coupling between visual information and body sway with binocular and monocular vision at two distances from the front wall of a moving room. Ten participants stood as still as possible inside of a moving room facing the front wall in conditions that combined room movement with monocular/binocular vision and distance from the front wall (75 and 150cm). Visual information effect on body sway decreased with monocular vision and with increased distance from the front wall. In addition, the combination of monocular vision with the farther distance resulted in the smallest body sway response to the driving stimulus provided by the moving room. These results suggest that binocularvision near the front wall provides visual information of a better quality than the monocular vision far from the front wall. We discuss the results with respect to two modes of visual detection of body sway: ocular and extraocular. (C) 2009 Elsevier Ireland Ltd. All rights reserved.

Functionality of the approach of hierarchical analysis in the full cost accounting in the IRP of a metropolitan airport

This work shows the application of the analytic hierarchy process (AHP) in the full cost accounting (FCA) within the integrated resource planning (IRP) process. For this purpose, a pioneer case was developed and different energy solutions of supply and demand for a metropolitan airport (Congonhas) were considered [Moreira, E.M., 2005. Modelamento energetico para o desenvolvimento limpo de aeroporto metropolitano baseado na filosofia do PIR-O caso da metropole de Sao Paulo. Dissertacao de mestrado, GEPEA/USP]. These solutions were compared and analyzed utilizing the software solution ""Decision Lens"" that implements the AHP. The final part of this work has a classification of resources that can be considered to be the initial target as energy resources, thus facilitating the restraints of the IRP of the airport and setting parameters aiming at sustainable development.

Prospects for control of African trypanosomiasis by tsetse vector manipulation

The extensive antigenic variation phenomena African trypanosomes display in their mammalian host have hampered efforts to develop effective vaccines against trypanosomiasis. Human disease management aims largely to treat infected hosts by chemotherapy, whereas control of animal diseases relies on reducing tsetse populations as well as on drug therapy. The control strategies for animal diseases are carried out and financed by livestock owners, who have an obvious economic incentive. Sustaining largely insecticide-based control at a local level and relying on drugs for treatment of infected hosts for a disease for which there is no evidence of acquired immunity could prove extremely costly in the long run. It is more likely that a combination of several methods in an integrated, phased and area-wide approach would be more effective in controlling these diseases and subsequently improving agricultural output. New approaches that are environmentally acceptable, efficacious and affordable are clearly desirable for control of various medically and agriculturally important insects including tsetse. Here, Serap Aksoy and colleagues discuss molecular genetic approaches to modulate tsetse vector competence.
