A tale of two bounties: the impact of competing fees on physician behavior

This study examines how the volume of privately insured services provided in hospital inpatient and outpatient departments changes in response to reductions in Medicare physician payments. We hypothesize that physicians consider relative payment rates when choosing which patients to treat in their practices. When Medicare reduces its payments for surgical procedures, as it did in the late 1980s, physicians are predicted to treat more privately insured patients because they become more lucrative. We use data from 182 hospitals for seventeen major procedures groups, covering a forty-five-month period between 1988 and 1991 that encom passes a twenty-four-month period before the reduction in Medicare fees and twenty-one months after the reduction. Our findings are consistent with the predictions for a number of procedure groups, but not for all of them. One implication of the findings is that societal savings from Medicare fee reductions are overstated if one does not also consider spillover effects in the private insurance market.     

Constitutional law in social choice perspective

Constitutional scholars do not typically employ spatial reasoning in their work. And yet, constitutional jurisprudence and much work in judicial politics implicitly rest on assumptions best cast in spatial terms. These include assuming that positions in constitutional disputes, and the views of Supreme Court justices, generally lie along a common liberal-to-conservative ideological dimension. Although the single dimension assumption is often appropriate, it suffers inherent limitations. First, Supreme Court decision-making rules, both within and across cases, expose problems of dimensionality. Second, important substantive doctrines likewise reveal dimensionality. Third, and finally, throughout the Supreme Court’s history, positions deemed liberal (or conservative) in one period have emerged as conservative (or liberal) in a later period, suggesting that dimensionality is a persistent feature in our jurisprudential history. Social choice proves uniquely suited to explaining these important aspects of constitutional law. After briefly introducing the discipline of constitutional law and its relationship to social choice, this article offers three illustrations of how social choice analysis deepens our understanding of important substantive areas. The analysis exposes dimensionality within Supreme Court decision-making rules, within separation-of-powers doctrine, and over historical shifts in the liberal and conservative valence of once-prominent jurisprudential positions. Failing to appreciate dimensionality, which lies at the core of social choice theory, when studying the Supreme Court and constitutional law risks a truly one-dimensional understanding of a richer and multidimensional institution and body of doctrine.

School Resource Officers and the School to Prison Pipeline: Discovering Trends of Expulsions in Public Schools

Public school systems in America have come under scrutiny due to the harsh treatment of students by School Resource Officers (SROs). Incidents of armed, uniformed police in schools affecting physical arrests in American classrooms seem to be ever more frequent in news cycles, likely due to the ease of capturing these events on video via cell phones of bystanders. Of particular note, visceral reports of “heavy-handed” SROs reinforce a consistent narrative from some media outlets suggesting that the simple presence of these officers inside schools leads to student arrests for behaviors that can arguably be dealt with by the school administration in a reintegrative manner. The apparent lack of school discretion and the presence of strict zero tolerance policies are at the root of an issue that has been termed the “School to Prison Pipeline” by mass media. SROs are often the exclusive focus of this issue, typically as a symbol of a school’s dedication to strict enforcement of rigid rules.     

The contemporary cybercrime ecosystem: A multi-disciplinary overview of the state of affairs and developments

This article provides a multi-disciplinary overview of the contemporary cybercrime ecosystem and its developments. It does so by reviewing and synthesising recent cybercrime research from fields such as cybersecurity, law and criminology. The article also examines ways in which gaps between the aforementioned fields arise and how to lessen them to increase cybersecurity. This article is divided into four main parts. The first part offers background on cybercrime and some of its main elements. It defines terminology, sets out a legal taxonomy of cybercrime offences and presents the estimated costs, threat agents and characteristics of various illicit activities and technical aspects of cybercrime. Parts two, three and four build on this preceding analysis by (separately) examining three prominent threat vectors within the ecosystem – malware, the darknet and Bitcoin and other cryptocurrencies. For each threat vector, the article identifies and investigates features, history, functions and current and expected states of development within the ecosystem. Through its attention to and synthesis of current research and results from different fields, this article offers a synoptic account of the cybercrime ecosystem, which can bridge potential knowledge gaps between fields.
