This paper addresses the need of finding new ways of measuring environmental and economic performance of farming. The aim of this study is to inquire on the impacts that excessive intensification has on productivity and environmental costs in the long term and, additionally to explore empirically the trend of these two indicators over time. The contribution of this study is twofold: (a) to engage in the discussion that although intensification can boost yields and lower costs in the short-term, it might lead in the opposite direction in the long-term due to environmental and economic issues and (b) to explore current trends of productivity and environmental costs of farming. To this end, this paper performs a panel data analysis of productivity and environmental costs on a farm accounting database across European regions over the 1989-2009 period. The methodology uses output as an indicator of productivity and expenditures on energy, pesticides and fertilisers as proxy indicators of environmental costs. Results provide empirical evidence that regions under study have a negative trend of productivity and a positive trend of environmental costs in the years under study. These results correlate negatively with both, economic and environmental sustainability of farms. Arguably, this is aggravated in the latter due to hidden environmental costs valued at zero in traditional accounting.

This paper investigates the impact of firm and partner tenure on audit quality, where audit quality is proxied by discretionary accruals. We study a sample of Spanish listed companies between 2005 and 2011 and address both the individual and the interaction effects of firm and partner tenure. Our study is motivated by the current debate, particularly intense at the EU level, on the impact of the auditor rotation regime on the quality of auditing. We find that, without considering the interaction effects, firm and partner tenure do not seem to play a relevant role as determinants of audit quality. Importantly, the interaction of firm and partner tenure shows stronger effects on audit quality than both forms of tenure separately considered. Finally, our analysis suggests that audit quality is maximized when medium firm and partner tenures interact. However, results for the interaction variables are sensitive to the accruals estimation method.

We investigate whether long audit partner tenures impair auditor independence, as proxied by the opinion of the audit report, with a sample of Spanish companies for the period: 2002-2010. The Spanish audit market constitutes an ideal setting in which to address this issue, as it is characterized by unusually lengthy engagements with the audit firm. The motivation relies, on the one hand, on the current discussion about the necessity to reinforce the independence of auditors and, on the other hand, on the very limited available research at the partner level. The main result is the lack of significant effects of partner tenure on independence. This finding is robust to various checks. Unlike prior research, we also address the joint effects of firm and partner tenure on independence. Results indicate that partner tenure does not compromise independence, even under long or extremely long audit firm tenures. These findings might have some interesting policy implications, in particular for the intense current debate on auditor rotation regimes which is taking place within the European Union.

The European Commission's Green Paper on Audit Policy has raised serious concerns about external auditor independence and also encouraged further research about the implications of long audit firm tenures. We examine the effects of audit firm tenure on independence, while measuring independence using the audit report opinion with a sample of Spanish public companies for the period 2002-2009. Generally, prior research has limited to the examination of modified going-concern opinions to financially distressed firms. This approach limits the generalization of results as well as the ability to address the traditional auditor role in the classical corporate governance scheme. To address these issues, we propose a multinomial approach which not only includes all types of audit qualifications in the analysis, but also considers the implications of going-concern opinions for the auditor-client relationship. Our results show that auditors seem willing to sacrifice independence in lengthy engagements, but only for non-going-concern modified opinions. This finding is robust to various proxies of accounting quality.

The 2010 Green Paper on Audit Policy by the European Commission has explicitly questioned the sufficiency of audit rotation rules established by European Union Members to guarantee auditor independence. In addition, the Paper clearly states that more research is needed regarding the effects of long audit tenures on independence. In this article, we have replicated the research by Ruiz-Barbadillo, Gómez-Aguilar, and Biedma (2005) about the effects of audit firm tenure on independence with more updated data. However, unlike them, we have performed panel data estimations instead of pooled regression. Our approach allows for a better control of individual unobserved heterogeneity, thus reducing potential problems caused by omitted variable bias. While Ruiz-Barbadillo et al. reported an unexpected positive effect of tenure on the likelihood of audit qualifications, we do not show any significant effect of tenure on the opinion of the audit report. Our results are robust to various sensitivity analyses.

While conventional farming systems face serious problems of sustainability, organic agriculture is seen as a more environmentally friendly system as it favours renewable resources, recycles nutrients, uses the environment's own systems for controlling pests and diseases, sustains ecosystems, protects soils, and reduces pollution. At the same time organic farming promotes animal welfare, the use of natural foodstuffs, product diversity and the avoidance of waste, among other practices. However, the future of organic agriculture will depend on its economic viability and on the determination shown by governments to protect these practices. This paper performs panel regressions with a sample of Catalan farms (Spain) to test the influence of organic farming on farm output, costs and incomes. It analyses the cost structures of both types of farming and comments on their social and environmental performance.

Directive 2014/56/EU and Regulation (EU) No. 537/2014, which came into effect in June 2016, introduced the mandatory rotation of audit firms after a maximum period of 10 years with the same client. We conduct a cross‐European study with the aim of assessing whether long audit firm tenures are associated with lower levels of audit quality. The sample for the study is based on the constituents of the Standard & Poor's Europe 350 index for the years between 2009 and 2016, and we utilize three different sets of proxies for audit quality: discretionary accruals, differences between reported earnings and earnings benchmarks, and accounting restatements. The main result of the study finds that companies with more than 10 years of tenure with their auditors do not have a lower audit quality than other firms. In fact, this study provides some evidence of a higher audit quality for these firms. The results are robust to various checks. Therefore, if there does not seem to be a problem of a lack of audit quality associated with long audit firm tenures, the necessity of establishing a maximum tenure, as the new European regulation does, may be questioned.

Should we expect a gender effect on the quality of audit services? Both the behavioural economics literature and the glass ceiling for women in the audit profession suggest an affirmative answer to this question. We conduct the study with a sample of Spanish-listed companies for the period between 2008 and 2015 and use the quality of the client's financial statements as a proxy for the quality of audit services. The results provide sound and consistent support for a positive female auditor effect on the quality of audit services. Although our figures suggest that men and women tend to audit different types of clients, the results are not driven by these differences. Moreover, the gender effect occurs from the very first year of the appointment of a female partner to replace a male auditor. This study may contribute to challenging stereotypes and may be informative for the ongoing political debate regarding the under-representation of women in senior management levels.

[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. ; [eng] This research finds neither significant differences in earnings and revenues for farms using fair value (FV) for biological assets with respect to those valuing at historic cost (HC), nor an increase in their volatility. It does not bring about differences in profitability, accounting manipulation and farm cash flows predictability either. On the contrary, most tests reveal higher predictive power of future earnings under FV. The study also provides evidence on flawed HC accounting practices in the agricultural sector and concludes that FV seems an interesting tool for the predominant small holdings in the agricultural sector in the European Union.

This study investigates audit quality under joint and single audit regimes with a sample of large European firms. Both, the economic relevance of these companies, and the fact that the impact of joint audit on audit quality should be stronger when the audited company is a blue-chip firm motivate the study. If mandatory joint audit were positively associated with audit quality, French firms, under mandatory joint audit since 1966, should present higher audit quality compared to their European peers. The results do not indicate this to be the case. Specifically, similar levels of discretionary accruals are observed for French and other European firms. Furthermore, for the first time in the literature, evidence is reported indicating that French firms may even present lower audit quality than their European peers, when audit quality is measured by the likelihood of just beating earnings benchmarks. These results are expected to inform the ongoing debate in several countries about joint audits.
