Cooperative Management of Groundwater Resources in the Presence of Environmental Externalities

This paper investigates how cooperation among users can achieve a better management of groundwater in the presence of environmental externalities. Cooperation allows users to internalize the damages caused by their activities and reduce extractions. The paper develops a game theoretical framework to assess the value of cooperation in an aquifer that is divided into three sub-aquifers that are being overly exploited. Two types of externalities are modeled: first, water extractions in each sub-aquifer impact water levels in neighboring sub-aquifers (extraction externality). Second, the three sub-aquifers are also connected to an ecosystem and thus decisions in each sub-aquifer affect the health of the ecosystem (environmental externality). A cooperative game theory model is applied. The model empirically shows how the uncontrolled extractions in each sub-aquifer affects neighboring groundwater users but also cause severe impacts to the linked ecosystem. The model is tested empirically in one of the most important aquifers in Spain, the Eastern la Mancha aquifer. The results illustrate how both extraction and environmental externalities interact in affecting the likelihood of cooperation among the users. The paper estimates the value of cooperation and its stability with and without the environmental externality.     

Press release disclosures in Spain and the UK

Despite acknowledging the importance of different types of press releases in the accounting literature, researchers have conducted little systematic empirical research on this topic. To address this issue the present study examines the antecedents of a firm's decision to issue an Annual Results Press Releases (ARPRs) in a cross-national context, using Spain and the UK. The study investigates for the first time the relationship among ARPRs, earnings performance, the existence of an investor relations department (IRD), company size, and ownership concentration. Using a sample of 246 publicly traded Spanish and UK companies, this article shows that the two countries have significant differences in the disclosure of press releases. Moreover, size and the existence of an IRD were found to have a significant and direct effect on the disclosure of press releases. Finally, the results also indicate that ownership structure and company size play an important role as moderators to explain the effect on disclosure of press releases. Implications of these findings along with limitations and directions for further research are discussed.     

Corporate governance and impression management in annual results press releases

We study the association between corporate governance and impression management in annual results press releases (ARPRs). Press releases constitute a timely vehicle to communicate firm performance to third parties but they can be manipulated to distort readers’ perceptions of corporate achievements. We predict that governance mechanisms actively monitor managerial disclosures, improving firm transparency and thus reducing impression management in ARPRs. The results confirm that strong governance limits impression management, consistent with governance monitoring effectively reducing self-serving disclosures by management. Our evidence suggests that management disclosure practices respond, at least partly, to informative motivations. We also show that strong governance firms are more likely to release an ARPR.     

Do Non-socially Responsible Companies Achieve Legitimacy Through Socially Responsible Actions? The Mediating Effect of Innovation

This study investigates the effects on organization’s financial performances of, first, the extent to which the organizations are involved in controversial business activities, and second, their level of social performance. These companies can be considered non-socially responsible given the harmful nature of the activities they are involved in. Managers of these companies may still have incentives to pursue socially responsible actions if they believe that engaging on those actions will help them to achieve legitimacy and improve investors’ perception about them. We develop a comprehensive methodology to investigate these corporate social performance (CSP)-related effects in a complex but specific setting. To this end, we analyze a sample of 202 US firms for the period 2005–2008 using a novel method in this area: partial least squares. Our results indicate that, contrary to the general findings in prior literature, companies involved in controversial business activities which engage in CSP do not directly reduce the negative perception that stakeholders have about them. Instead, we found evidence of a positive mediation effect of CSP on financial market-based performance through innovation.     

Groundwater and ecosystems damages: Questioning the Gisser-Sánchez effect

Gisser and Sánchez (1980a) state the conditions under which welfare gains from policy intervention are negligible in aquifer management, when compared with non-regulation or “free market” outcomes. This is the so-called Gisser-Sánchez effect (GSE), which has been supported by the ensuing literature during recent decades. The GSE requires a number of assumptions, among which is the disregard for aquatic ecosystems linked and dependent on aquifer systems. The depletion of aquifer systems in arid and semiarid regions worldwide is causing acute water scarcity and quality degradation, and leading to extensive ecosystem damages. This study shows that by including environmental damages into the analytical model, results can change substantially. The analysis highlights both theoretically and empirically the importance of policies in groundwater management, as well as the potential role for stakeholders' cooperation. The empirical application deals with two large aquifers in Spain, the Western La Mancha aquifer which is grossly mismanaged, and the Eastern La Mancha aquifer, which is moving towards sustainable management. Western and Eastern La Mancha aquifers illustrate that policies and institutions are essential to avoid the current global aquifer mismanagement.     

Opportunistic disclosure in press release headlines

This paper examines managerial, self-serving, disclosure practices in the headlines of press releases announcing annual results. Headlines are a framing feature that can be used to capture and retain attention with the ultimate intention of affecting the thoughts and feelings of readers, thus influencing their opinions. Therefore, headlines have a key role in a company's communication strategy. Using a large sample of Spanish listed companies for the years 2005 and 2006, we provide evidence of persistent impression management in press release headlines. Companies, irrespective of whether they perform well or badly, are inclined to stress good news and downplay bad news. Companies with very small profits report surprising amounts of good news. We provide evidence that companies are selective in the performance figures they include in the headlines of press releases. In particular, the disclosure of profits or sales figures in press release headlines is also associated with earnings performance. Finally, we find that larger firms are more likely to issue press releases than smaller ones, consistent with the theory that highly visible firms face a greater demand for information transparency.     

Quarterly earnings guidance and real earnings management

We examine if quarterly earnings guidance induces real earnings management. Quarterly guidance may cause myopia and inefficient decision-making, if managers become overly concerned with setting and beating short-term earnings targets. We test these associations on a large sample of US firms. Our evidence suggests that quarterly guidance is informative and lowers myopic incentives. However, our analyses also reveal endogenous associations exist between guidance and real earnings management. In contrast with existing concerns over frequent guiders, we find that guidance appears problematic in infrequent guiders, and in firms that issue good news earnings guidance and that operate in settings where earnings pressures are high.
