Partial information and volatility in a two-bloc world

This paper examines the effects of partial information on volatility and on the design of simple feedback rules in a rational expectations context. Previous studies have investigated these effects using small analytical models. Here we employ an empirical two-bloc model derived from the OECD Interlink model. The main conclusions are that when current asset prices are observed, but GDP is observed with a delay, then the effect on volatility is small, compared to the full information case. Likewise the choice of simple feedback rules is little affected, although a non-optimal use of information in their design may lead to a deterioration in performance.     

Complexity Theory &; Socio-Legal Studies

The complexity theory paradigm is in the process of being taken up from the natural sciences into the social sciences and humanities. This article introduces complexity theory as a theoretical framework for socio-legal study. Complexity theory is analysed as being developed in non-organic, organic and social registers, and as exhibiting a specific image of thought. The complexity theory of the non-organic register is introduced in terms of Prigogine’s work on order out of chaos and dissipative structures. The complexity theory of the organic register is introduced in terms of Kauffman’s work on edge of chaos self-organisation in morphogenesis and co-evolution. Finally, the complexity theory of the social register is addressed in terms of assemblage theory. Specifically addressing the level of social organisation and the role of law, the work of J.B. Ruhl is considered as the first working through of the implications of complexity theory for socio-legal scholarship. The article goes on to argue that the key starting points of a complexity paradigm for socio-legal study are: an ontogenetic image of thought; complex dynamic dissipative structures and assemblages in phase space; the socio-legal as complex adaptive assemblages in co-evolution with their broader environment; and commitment to emergence and self-organisation at the edge of chaos. In particular, it proposes that the complexity theory of law allows for the search for lost, hidden, local, bottom-up, emergent modes of legality, and for a new conceptual creativity in socio-legal work. The complexity theory theoretical framework is of particular interest and challenge to scholars working in the social sciences with Maturana & Varela based autopoetic systems theory.     

The Intersection of Intimate Partner Violence and Traumatic Brain Injury: A Call for Interdisciplinary Research

An emerging body of research suggests that survivors of intimate partner violence (IPV) are at a high risk for sustaining traumatic brain injury (TBI). However, most scholars and practitioners working on the problem of IPV have not examined how TBI could be related to their familiar subject of study. Concomitantly, little work in the brain injury field has been done to examine TBI in the context of IPV. In this paper, we encourage cross-collaboration among these fields. To that end, we consider the relationship between IPV and TBI; the difficulty in detecting and measuring the IPV-related TBI and ethical concerns that may arise when addressing this issue. Our work emphasizes the need to recognize the complex interplay among psycho-physiological health and socio-cultural contexts. As such, we present a socio-ecological perspective of IPV-related TBI to provide a contextual framework to guide future interdisciplinary research. Finally, we outline directions for future research.     

A comparative analysis of conviction outcomes of American domestic terrorists

This research uses quantitative analyses to determine whether or not conviction outcomes differ across three major American domestic terrorism groups: ecoterrorists, left-wing extremists, and right-wing extremists. Findings suggest that ecoterrorists receive lighter treatment within the criminal justice system while controlling for important variables, such as gender, age, and count severity. Findings highlight differences between “home-grown” terrorist groups, departing from a large segment of terrorism research focused on domestic versus international comparisons or terrorist versus civilian comparisons. Results elicit new research questions to understand why domestic terrorists receive differential treatment within the criminal justice system, despite controlling for key variables.     

A quasi-experimental test of the effects of criminal justice involvement on later mental health

Objectives

While many criminological theories posit causal hypotheses, many studies fail to use methods that adequately address the three criteria of causality. This is particularly important when assessing the impact of criminal justice involvement on later outcomes. Due to practical and ethical concerns, it is challenging to randomize criminal sanctions, so quasi-experimental methods such as propensity score matching are often used to approximate a randomized design. Based on longitudinal data from the Cambridge Study in Delinquent Development, the current study used propensity score matching to investigate the extent to which convictions and/or incarcerations in the first two decades of life were related to adverse mental health during middle adulthood.

Methods

Propensity scores were utilized to match those with and without criminal justice involvement on a wide range of risk factors for offending.

Results

The results indicated that there were no significant differences in mental health between those involved in the criminal justice system and those without such involvement.

Conclusions

The results did not detect a relationship between justice system involvement and later mental health suggesting that the consequences of criminal justice involvement may only be limited to certain domains.

     

Jurisdictional integration: A framework for measuring and predicting the depth of international regulatory cooperation in competition policy

This article takes a new approach to international regulatory cooperation by developing a concept of the depth of cooperation, jurisdictional integration. A dataset of international competition policy agreements is compiled and ranked against an ordinal index of the depth of de jure cooperation in enforcing competition policies. There has been both a deepening and broadening of de jure cooperation over time. Statistical analysis finds that common membership of the Organisation for Economic Co‐operation and Development is a strong predictor of the depth of agreements to cooperate in enforcing competition policies; that we can be confident that the depth of agreements is low when signatories' substantive competition laws are dissimilar; and that the depth of de jure cooperation is a strong predictor of whether an agreement is “intergovernmental” or “transgovernmental.” The article puts forward a new way to map and measure international regulatory cooperation, and a new variable for use in research on its causes and consequences.
