掠夺性定价的经济学及法律分析——美国和欧盟的经验与趋势

掠夺性定价一般表现为企业为排挤、制约竞争对手或阻碍竞争对手进入市场而在相当长的一段时期内故意将价格设置于其成本之下。其目的是为将竞争对手逐出市场并随后设定高于竞争水平的价格,以收回前期降价的损失。《中华人民共和国反垄断法》以及其他相关的法律法规都包含了禁止掠夺性定价的规定。然而,对于掠夺性定价中的一些具体问题还没有相应的法制规章提供指引和解读,再加上此类案件法院判决的先例在中国现阶段还属少见,因此,本文将详细讲解近年来美国和欧盟的经济学家、反垄断机构以及法院对此类经典案件(如Wanadoo案等)的审理分析经验与趋势,以供借鉴。     

NEXT STEPS IN THE EVOLUTION OF ANTITRUST LAW: WHAT TO EXPECT FROM THE ROBERTS COURT

Under the leadership of Chief Justice John G. Roberts, Jr.,the Supreme Court has demonstrated a willingness to cast asidethe Court's prior antitrust decisions. The qualified per serule applicable to tying surely will not survive much longer,but what else might be in store is more speculative. This essayidentifies four decisions relating to competitor collaborationin which the Court's prior application of the per se rule doesnot comport with its modern decisions. In two of the cases,the conduct likely would be found lawful today; while in theother two, the conduct most likely still would be condemnedbut only after an abbreviated application of the rule of reason.This essay also identifies three legal doctrines ready for retirement.They are the absolute requirement of market delineation as apredicate for merger analysis, the outmoded approach to marketdelineation of Brown Shoe, and the unhelpful formulation ofthe monopolization offense in Grinnell.     

Risk assessment in offenders with intellectual disability: a comparison across three levels of security

In mainstream offender samples, several risk assessments have been evaluated for predictive validity. This study extends this work to male offenders with intellectual disabilities. Participants from high-, medium-, and low-security settings, as well as community settings, were compared on a range of risk assessments. The Violence Risk Appraisal Guide, HCR-20-Historical Scale, the Risk Matrix 2000-C (combined risk), and the Emotional Problems Scales-Internalising discriminated between groups, with participants from high security having higher scores than those in medium security, who had higher scores than those in the community. The Violence Risk Appraisal Guide, all HCR-20 scales, the Short Dynamic Risk Scale, and the Emotional Problems Scales (Internalising and Externalising) showed significant areas under the curve for the prediction of violence. The Static-99 showed a significant area under the curve for the prediction of sexual incidents. The discussion reviews the value of these various scales to intellectual disability services.
