The Limitations and Potential of Behavioural Remedies under Merger Regulation : Focusing on the Debate about Investment Commitments in the UK
No full text論説In recent years, there has been lively discussion in the UK regarding what industrial policy considerations should be taken into account when interpreting and enforcing merger regulation. In the context of promoting economic growth and investment, behavioural remedies such as investment commitments have been attracting attention. While legally binding, investment commitments are classified as behavioural remedies. Although structural remedies are generally agreed to be desirable, the Competition & Markets Authority（CMA）approved the Vodafone/Three merger solely through behavioural remedies, primarily investment commitments. Furthermore, the CMA is currently reviewing its approach to merger remedies and has begun revising its guidance. However, there are several concerns; for example, investment commitments require ongoing monitoring, as they may not permanently restore competition. These concerns require careful design of behavioural remedies. If investment commitments are to be introduced, the current regulatory environment needs to be examined, specifically relating to the function of other governmental departments and regulatory authorities. Outside regulated areas, unlike the Vodafone/Three merger, the role of monitoring trustees may become a crucial issue. Going forward, the strategic development of Japanʼs monitoring trustees in terms of quality, quantity, and technical capabilities may become an important aspect of competition policy.日本学術振興会25K04787SDGsと経済法―脱炭素・人権DD・人口減少・経済安全保障を中心として―本稿は、2025 年度科学研究費補助金（基盤研究（C）、課題番号：25K04787）による研究成果の一部である

No full textDetecting Bubbles by Machine Learning Prediction.
No full textThis study explores the potential of machine learning, Long Short-Term Memory (LSTM), to detect asset price bubbles by analyzing prediction errors. Using monthly data of the Nikkei225 Index, I evaluate the performance of LSTM model in forecasting prices and compare with the GSADF test. I find that LSTM’s prediction accuracy significantly deteriorates during periods associated with asset bubbles, suggesting the presence of structural changes. In particular, the LSTM approach of this paper captures both the emergence and collapse of Japan’s late 1980s bubble separately. In addition, it can also capture structural changes related to policy changes in the 2010s Japan, which are not identified by the GSADF test. These findings suggest that machine learning can be used for not only identifying bubbles but also policy evaluations
Revisiting the Necessity of the Defense Attorneysʼ Right to Be Present During Interrogations of Suspects in China : On the Occasion of the Fourth Amendment to the Criminal Procedure Law
No full text葛野尋之先生 名誉教授称号授与記念The purpose of this paper is to re-examine the necessity of the defense attorneysʼ right to presence during interrogations in criminal proceedings in China. Since the implementation of the Criminal Procedure Law in 1979, Chinaʼs judicial practice has been dominated by the inquisitorial mode of investigation under the framework of authoritarianism and investigation-centrism, severely constraining the rights of criminal suspects and defendants. Within this procedural architecture, the lack of effective checks on investigative power has led to frequent unlawful interrogations, such as extorting confessions through torture. From the 1990s to the early 2000s, a series of major wrongful convictions, in particular capital cases, were exposed, revealing the systemic deficiencies of the centrality of investigation, and prompting profound reflection on the standardization of the interrogation process in both academic and practical circles. Through three rounds of criminal justice reform, although the protection of the rights of the accused – centered on the right to defense – has been strengthened, the leniency system for the admission of guilt and the acceptance of punishment established by the 2018 legal amendments has devolved into a catalyst for a confession-centered doctrine in practice. This not only erodes the accusedʼs right to voluntary statements but also heightens the risk of wrongful convictions and undermines the foundation of judicial fairness. Resolution of this dilemma hinges on establishing the defense attorneysʼ right to presence during interrogations. This right would effectively restrain illegal investigative practices and provide real-time legal support ; it would also ensure timely access to case information and optimize defense strategies and ultimately fulfill the constitutional commitment to effective defense. The ongoing fourth-round amendment to the Criminal Procedure Law urgently requires drawing on international criminal justice standards to codify and institutionalize the defense attorneysʼ right to presence during interrogations, while ensuring its effective implementation through supporting mechanisms
