Limited Liability and Imperfect Information—On the Existence of Safety Equilibria Under Products Liability Law

In the literature on the economics of tort law the Cournot-Nash equilibrium concept has been undisputed. In particular, the existence of a Cournot-Nash safety equilibrium has been taken for granted, given the usual convexity assumptions. In this paper a simple model of strict liability with the defence of contributory negligence is considered. Liability is assumed to be limited. It is shown that for a certain range of liability limits no Cournot-Nash safety equilibrium in pure strategies exists. A mixed strategy equilibrium exists but it turns out to be suboptimal.     

Forensic veterinary radiology: Ballistic-radiological 3D computertomographic reconstruction of an illegal lynx shooting in Switzerland

The lynx, which was reintroduced to Switzerland after being exterminated at the beginning of the 20th century, is protected by Swiss law. However, poaching occurs from time to time, which makes criminal investigations necessary. In the presented case, an illegally shot lynx was examined by conventional plane radiography and three-dimensional multislice computertomography (3D MSCT), of which the latter yielded superior results with respect to documentation and reconstruction of the inflicted gunshot wounds. We believe that 3D MSCT, already described in human forensic-pathological cases, is also a suitable and promising new technique for veterinary pathology.     

Performance in Public Organizations: Clarifying the Conceptual Space

Performance in public organizations is a key concept that requires clarification. Based on a conceptual review of research published in 10 public administration journals, this article proposes six distinctions to describe the systematic differences in performance criteria: From which stakeholder's perspective is performance being assessed? Are the criteria formal or informal? Are the criteria subjective? Which process focus and product focus do they have, if any? What is the unit of analysis? Based on these distinctions, the performance criteria of existing studies used in an empirical review of management and performance are classified. The results illustrate how a systematization of the conceptual space of performance in public organizations can help researchers select what to study and what to leave out with greater accuracy while also bringing greater clarity to public debates about performance.     

Imperfect adaptation: how the WTO and the IMF adjust to shifting power distributions among their members

How do international institutions adjust to shifting power distributions among their members? We argue that institutional adaptations to the rise of emerging and the decline of established powers are different from what power transition theories (PTTs) would lead us to believe. Institutional adaptations are not impossible, as pessimist PTT variants hold; and they are rarely easy to attain, let alone perfect, as optimist PTT variants imply. To bridge the gap between these versions of PTT, we propose an institutionalist power shift theory (IPST) which combines insights on the conditions and mechanisms of institutional change from functionalist, historical and distributive variants of rational institutionalism. IPST claims that institutional adaptations will succeed or fail depending on whether or not emerging powers are able to undermine the international institution and to make credible threats to this effect. To demonstrate IPST’s plausibility we analyze: (1) how India and Brazil gained the agreement of established powers to their membership in the WTO core negotiation group (“Quad”), which had previously been dominated by developed countries; and (2) how China reached agreement with established powers on (more) even-handed surveillance of IMF members’ financial stability, which, up to then, had focused on developing countries and exchange rate issues.     

The Self-Report Symptom Inventory (SRSI): a New Instrument for the Assessment of Distorted Symptom Endorsement

Self-report instruments to detect distorted symptom reporting play a crucial role in clinical and forensic psychology. Most of the instruments currently available for this purpose only list implausible symptoms, which makes them easily identifiable as symptom validity tests. We developed the Self-Report Symptom Inventory (SRSI), combining five self-report scales of genuine symptoms with five pseudosymptom scales to screen for distorted symptom reporting in various domains (e.g., depression, post-traumatic stress). With a preliminary questionnaire version, we collected data in a heterogeneous sample (N?=?239) and performed an item selection, resulting in the final 107-item version. This version was evaluated in civil forensic patients, inmates of a prison, and a population-based sample; N?=?387). Data show that (a) SRSI pseudosymptom scores correlate highly (≥.80) with other instruments tapping distorted symptom endorsement, notably the Structured Inventory of Malingered Symptomatology; (b) High SRSI pseudosymptom scores tend to correlate with underperformance; and (c) The psychometric features of the SRSI are satisfactory, with internal consistency for the total scales >.90 and retest reliability >.85. The instrument appears to be a promising tool for examining symptom exaggeration, but further work is required, in particular cross-validation with other samples and different methods.
