Voluntary disclosure under imperfect competition: Experimental evidence

This study investigates disclosure behavior when a manager has incentives to influence the actions of a product market competitor in a Cournot duopoly. Theoretical research suggests that under various conditions the manager has incentives to withhold some signals and disclose others. Using an experimental economics method, we find support for partial information disclosure. Our results suggest that when the manager receives private information about industrywide cost, unfavorable (favorable) information is disclosed (withheld) and the competitor adjusts production accordingly. In contrast, when the manager receives private information about firm-specific cost, disclosure behavior is not affected by the favorableness of the information and the competitor's production decision is invariant to the disclosure choice.Information theory ; Microeconomics

Taxpayer Information Assistance Services and Tax Compliance Behavior

The traditional "enforcement" paradigm of tax administration views taxpayers as potential criminals, and emphasizes the repression of illegal behavior through frequent audits and stiff penalties. However, an important trend in tax administration policies in recent years is the recognition that this paradigm is incomplete. Instead, a revised "service" paradigm recognizes the role of enforcement, but also emphasizes the role of tax administration as a facilitator and a provider of services to taxpayer-citizens. This research utilizes laboratory experiments to test the effectiveness of such taxpayer service programs in enhancing tax compliance. Our basic experimental setting mimics the naturally occurring environment: subjects earn income, they must choose whether to file a tax return, and they then must choose how much of their net income to report to a tax authority that may audit the subject. To investigate the effects of taxpayer services, we "complicate" these compliance decisions of subjects, and then provide "services" from the "tax administration" that allow subjects to compute more easily their tax liabilities. Our results indicate that uncertainty reduces both the filing and the reporting compliance of an individual. However, we also find that agency-provided information has a positive and significant impact on the tendency of an individual to file a tax return, and also on reporting for individuals who choose to file a return.tax evasion, tax compliance, behavioral economics, experimental economics

Ethics and governance in social work research in the UK

The application of formal research ethics and governance structures in social work research have lagged behind those applicable in health, although in the UK, social care has been deemed to be covered by those that were used in the NHS. Whilst this link is useful, it does not facilitate researcher involvement in the small-scale qualitative studies that feature in social work more than in health. Our exploration of the subject reveals that the dominance of the natural sciences paradigm in the social science is evident nationally, regionally and internationally. So, in this sense, the UK follows the usual paths that favour quantitative studies. In this article we explore the trajectory of governance structures in social work research in the UK to argue that social work needs its own ethics and governance structures, but that some agreement should be sought with other professions, particularly in those projects that cross professional and discipline boundaries so that social work research does not have to undergo dual processes for ethical approval. This implies a broader recognition of social work research ethics and governance structures than currently exist. © The Author 2008.

Confirmation Bias: The Pitfall of Forensic Science

As it stands, forensic science and its practitioners are held in high regard in criminal court proceedings due to their ability to discover irrefutable facts that would otherwise go unnoticed. Nevertheless, forensic scientists can fall victim to natural logical fallacies. More specifically, confirmation bias is “a proclivity to search for or interpret additional information to confirm beliefs and to steer clear of information that may disagree with those prior beliefs” (Budlowe et al., 2009, p. 803). To restore the integrity of the forensic sciences, the sources of confirmation bias need to be identified and eliminated. Accordingly, empirical studies have given substance to a subject that is intangible and thus difficult to recognize. Inherent and external sources of confirmation bias include the dependence and association of crime labs upon police agencies and the amount of extraneous information made available to verifying examiners. Potentially effective solutions offered to minimize its influence upon the conclusions made by forensic scientists include the privatization of crime labs, the establishment of educational requirements for forensic examiners, the separation of testing and interpretation, and the institution of double blind testing. This effort must be undertaken as the justice system relies on forensic sciences to provide meaningful evidence that can play a prominent role in the fate of those who stand trial

Is brain activity observable that leads to an evaluation of a probability of 0.5 that is different from 0.5 in binary lottery choices?

This paper focuses on the problem of probability weighing in the evaluation of lotteries. According to Prospect Theory a probability of 0.5 has a weight of smaller than 0.5. We conduct an EEG experiment in which we compare the results of the evaluation of binary lotteries by certainty equivalents with the results of the bisection method. The bisection method gives the amount of money that corresponds to the midpoint of the utilities of the two payoffs in a binary lottery as it has been shown previously. In this method probabilities are not evaluated. We analyzed EEG data focused on whether a probability is evaluated or not. Our data show differences between the two methods connected with the attention towards sure monetary payoffs, but they do not show brain activity connected with a devaluation of the probability of 0.5.

Non-Duality

Self – organizing is closely connected to the phenomenon of life. The creation of complexity, which is necessary for the creation of life, is connected to the process of storing information in molecules of which the living cell is constituted. All living systems, either unicellular or multicellular organisms, are extremely complex systems compared to all the other species of the non living matter that exist in the Universe. Complexity is the result of effect processes, leading to systems with great organization, containing large information stocks. This organization of the molecules of a living organism, a result of accumulation of information, is what makes them able to produce useful work. The useful work involves both the fulfillment of basic biological processes, such as metabolism and reproduction, and the further increase in the information content that builds up in living systems. This last process is subject to the great chain of evolution of biological systems, this development is governed by the law of natural selection. The capability of reproduction, mutation and metabolism are necessary conditions for the latter
