Earnings management and audit adjustments: An empirical study of IBEX 35 constituents

Doubts about the reliability of a company's qualitative financial disclosure increase market participant expectations from the auditor's report. The auditing process is supposed to serve as a monitoring device that reduces management incentives to manipulate reported earnings. Empirical research confirms that it could be an efficient device under some circumstancesand recognizes that our estimates of the informativeness of audit reports are unavoidably biased (e.g., because of a client's anticipation of the auditing process). This empirical study supports the significant role of auditors in the financial market, in particular in the prevention of earnings management practice. We focus on earnings misstatements, which auditors correct with anadjustment, using a sample of past and current constituents of the benchmark market index in Spain, IBEX 35, and manually collected audit adjustments reported over the 1997-2004 period (42 companies, 336 annual reports, 75 earnings misstatements). Our findings confirm that companies more often overstate than understate their earnings. An investor may foresee earningsmisreporting, as manipulators have a similar profile (e.g., more leveraged and with lower sales). However, he may receive valuable information from the audit adjustment on the size of earnings misstatement, which can be significantly large (i.e., material in almost all cases). We suggest that the magnitude of an audit adjustment depends, other things constant, on annual revenues and free cash levels. We also examine how the audit adjustment relates to the observed market price, trading volume and stock returns. Our findings are that earnings manipulators have a lower price and larger trading volume compared to their rivals. Their returns are positively associated with the magnitude of earnings misreporting, which is not consistent with the possible pricing of audit information.

El impacto de los servicios sanitarios sobre la salud

This paper reviews what has increased medical-care spending bought in terms of health benefitswith longitudinal data from the U.S and, more limited, from Spain. Health services contributionto health has been positive in average, especially during the last 50 years for the U.S andthe last 30 years for Spain. This contribution differs among countries and is much greater forsome diseases (cardiovascular) than for others (cancer). Benefits from health care interventionscan be valued on basis on the social willin gness to pay, observed or declared on the process ofestablishing health policy priorities. 30.000 euros per Quality Adjusted Life Year could providean efficiency threshold for financing publicly health services in Spain: Consensus andlegitimacy of the political process of establishing health priorities becomes, however, moreimportant than any approximate number. Attention is paid finally to bridging the gap betweenefficacy (the possibilities given by innovation and resources devoted to health care) andeffectiveness (the distance to the frontier) of the everyday working of a health system with itsinappropriate care and limited application of the existing knowledge.

Hisenda pública europea: on som i on podríem arribar?

En un panorama econòmic mundial on les grans potències emergents creixen amb força i, com alguns informes recents de la OCDE apunten, la Xina es trobarà durant els propers anys en situació de sobrepassar els EEUU com a primera potència econòmica. En aquest context la Unió Europea apareix en una posició afeblida i els estats membres difícilment poden adoptar individualment un paper rellevant a nivell mundial. També comencen a sentir-se veus demanant una major integració al sí de la UE. Una de les opcions per assolir-la seria la creació d’una Hisenda Pública Europea. L’objecte d’estudi d’aquest treball serà la Unió Europea; més concretament la possibilitat d’assolir una Hisenda Pública Europea. Es pretén respondre a dues preguntes: Seria possible la creació d’una Hisenda Pública Europea? Com es podria estructurar? Per tal de poder respondre sòlidament aquestes qüestions s’analitzarà què s’ha fet fins ara en l’àmbit de la unió fiscal tant a la UE com a diversos països; quins passos es podrien donar per avançar cap a una Hisenda Pública de la Unió; i a quin model es podria arribar. També es contrastarà amb el marc teòric proposat, així com amb l’experiència prèvia de les diferents fases d’Integració Europea dutes a terme fins ara.

Polymorphisms of pyrimidine pathway enzymes encoding genes and HLA-B*4001 carriage in stavudine-associated lipodystrophy in HIV-infected patients.

: To assess in a cohort of Caucasian patients exposed to stavudine (d4T) the association of polymorphisms in pyrimidine pathway enzymes and HLA-B*4001 carriage with HIV lipodystrophy syndrome (HALS). 336 patients, 187 with HALS and 149 without HALS, and 72 controls were recruited. HALS was associated with the presence of a low expression, thymidylate synthase (TS) genotype polymorphism. Methylene-tetrahydrofolate reductase (MTHFR) gene polymorphisms and HLA-B*4001 carriage were not associated with HALS or d4T-TP intracellular levels. In conclusion HALS is associated with combined low-expression TS and MTHFR associated with high activity polymorphisms but not with HLA-B*4001 carriage.

Growth and reproduction of the dolphinfish (Coryphaena equiselis and Coryphaena hippurus) in the Canary Islands, Central-East Atlantic (preliminary results)

The size, growth and spawning characteristics of pompano dolphin (N=150) and common dolphinfish (N=36) caught off the Canary Islands between May and September 1995 and between July and September 1996 were examined. Fork length (FL) of pompano dolphin was in the range 28.3-62.8 cm. In 1995, the mean length increased significantly from June to September. However, in 1996, the mean length was significantly larger in July than in September. The overall length-weight relationship was W=0.0287*FL2.774 (r=0.97), while these relationships by sex were as follows: W=0.031*FL2.758 (r=0.98) and W=0.0282*FL2.776 (r=0.97), for males and females respectively. Spawning takes place at the beginning of the Summer (June-July). All the individuals obtained showed developing gonads, but females showed a higher gonadosomatic index (GSI) than males. The highest GSI values were obtained in June (x- =3.10±1.73), and decreased progressively towards the end of the season (September), when the average of this index was x- = 1.86±0.87. Similarly, the condition index decreased significantly from June to September. The proportion of females was always significantly higher than males, except in July 1996 when it was 1:1. There was a high correspondence between growth rates determined by annuli scale interpretation and modal progression analysis. According to scale annuli interpretation, the individuals caught showed more than five age classes. However, there are doubts about age assignation from scales. Fork length of common dolphinfish was in the range of 76.5-103.0 cm. The length-weight relationships obtained for all the specimens caught was W=0.00095FL3.527 (r=0.96), while these relationships by sex were as follows: W=0.00398FL3.222 (r=0.94) and W=0.01656FL2.873 (r=0.91), for males and females respectively. Spawning probably takes place at the beginning of the Summer. All the individuals obtained showed developing gonads, although the GSI of females were higher than males. The highest GSI values were obtained in June (x- =5.50±2.17). In the same way, the condition index decreased from May to June. The proportion of females was always slightly higher than males (1:1.4), but the ratio was not significantly different from 1:1

Martensitic phase transformation in rapidly solidified Mn50Ni40In10 alloy ribbons

Heusler alloy Mn50Ni40In10 was produced as preferentially textured ribbon flakes by melt spinning, finding the existence of martensitic-austenic transformation with both phases exhibiting ferromagnetic ordering. A microcrystalline three-layered microstructure of ordered columnar grains grown perpendicularly to ribbon plane was formed between two thin layers of smaller grains. The characteristic temperatures of the martensitic transformation were MS=213 K, Mf=173 K, AS=222 K, and Af=243 K. Austenite phase shows a cubic L21 structure (a=0.6013(3) nm at 298 K and a Curie point of 311 K), transforming into a modulated fourteen-layer modulation monoclinic martensite

Independent Central Banks: Low inflation at no cost?: A model with fiscal policy

In this article we extend the rational partisan model of Alesina and Gatti (1995) to include a second policy, fiscal policy, besides monetary policy. It is shown that, with this extension, the politically induced variance of output is not always eliminated nor reduced by delegating monetary policy to an independent and conservative central bank. Further, in flation and output stabilisation will be affected by the degree of conservativeness of the central bank and by the probability of the less in flation averse party gaining power. Keywords: rational partisan theory; fiscal policy; independent central bank JEL Classi fication: E58, E63.

The Conservativeness of the Central Bank when Institutional Quality is Poor

We propose an extension of Alesina and Tabellini 's model (1987) to include corruption, which is understood as the presence of weak institutions collecting revenue through formal tax channels. This paper analyses how conservative should an independent central bank be when the institutional quality is poor. When there are no political distortions, we show that the central bank has to be more conservative than the government, except with complete corruption. In this particular case, the central bank should be as conservative as the government. Further, we obtain that the relationship between the optimal relative degree of conservativeness of the central bank and the degree of corruption is affected by supply shocks. Concretely, when these shocks are not important, the central bank should be less conservative if the degree of corruption increases. However, this result may not hold when the shocks are relevant.

La repercusión del régimen constitucional en la Iglesia de Lleida durante el trienio liberal

A principios del año 1820 la revolución de Rafael de Riego instauró el régimen liberal en España. La Iglesia de Lleida se adaptó correctamente al nuevo modelo político. Pero la obra legislativa de las Cortes liberales perjudicó gravemente a todas las estructuras políticas, económicas y sociales de la institución eclesiástica. Con la radicalización del gobierno liberal se produjo la ruptura de las relaciones de los con el Ayuntamiento de Lleida, quiénes al poco tiempo sufrieron la persecución y la represión de las autoridades liberales. Por tanto, el balance del período liberal fue muy negativo y su impacto enorme.
