Why do firms prefer after-hours disclosure? Evidence from Japan |
| 講演者 | 内田 交謹 氏
（早稲田大学商学学術院 教授） |
| 概要 | We exploit the Tokyo Stock Exchange’s (TSE’s) extension of its closing time from 3:00 p.m. to 3:30 p.m. in November 2024 to examine whether firms deliberately announce earnings after market close. The extension reduces the proportion of after-hours announcements by approximately 15%, indicating that operational constraints significantly influence announcement timing. Importantly, about 40% of firms announce earnings immediately after market close in both the pre- and post-extension periods, implying that many firms deliberately choose after-hours disclosure. We find that firms with more volatile stock returns consistently make after-hours announcements around the trading hours extension. These consistent after-hours announcements are also associated with lower ownership by relationship-based shareholders. Moreover, these factors are related to the likelihood that firms choose after-hours announcements for all earnings releases during the sample period. Finally, the market-to-book ratio—particularly its misvaluation component—is positively associated with the likelihood of making after-hours announcements. |

| テーマ | 東アジア半導体エコシステムの全貌と日台共創の未来―台湾半導体産業の発展を実業と政策の両面から支えてきたリーダーが語る ※日本語でのご報告 |
| 講演者 | 郭 智輝 氏（国立台北大学 客員教授） |
| 概要 | スマートフォンから最先端AI、自動車に至るまで、現代社会のインフラを支える半導体。現在、グローバルなサプライチェーンの再編と地政学的リスクの台頭により、東アジアの半導体産業は世界中からかつてない注目を浴びています。TSMCの日本進出に象徴されるように、日台の経済協力は今、単なる製造委託を超えた新たな局面を迎えています。本ワークショップでは、台湾の半導体企業を率いる経営者で、台湾の前経済産業大臣の郭智輝先生を特別ゲストにお招きします。熾烈なグローバル競争の最前線で培われた、経営者及び政治家としてのリアルな経験談を交えながら、台湾が世界をリードする強力な「エコシステム」を構築できた真髄に迫ります。激変する東アジア経済の中で、現在の半導体産業が直面する課題とは何か。そして、日本の強みと台湾の強みは何か、この二つを掛け合わせる「日台共創」は、どのようなイノベーションとスタートアップ体制を生み出し得るのか。第一線のトップ経営者の視点に触れながら、次世代のアジア経済とイノベーションの未来について共に議論を深める貴重な機会です。経済やテクノロジーの動向に関心のある方はもちろん、将来グローバルに活躍したい、あるいは起業を志す学生の皆さんの積極的なご参加をお待ちしています。 |

| テーマ | Coercive, Care, and Culinary Justifications: How Chefs Blend Old and New Forms of Management |
| 講演者 | Daphne Demetry 氏
（Associate Professor, Desautels Faculty of Management, McGill University） |
| 概要 | How does one manage when a core pillar of one’s management approach becomes contested? We explore this case using the fine dining industry, which is facing a moment of change as the historically institutionalized model of hierarchical and abusive management has given way to an emerging management style that emphasizes individualized care and personal growth. Analyzing 120 interviews with fine dining chefs across the US (San Francisco and New York City), we examine how chefs justify the managing of their staff through the lens of two management ideologies, which we call broadly “coercive” and “care.” We find that most chefs use instrumental justifications to integrate a new caring management approach – e.g., it results in better quality food and higher employee retention. At the same time, they retain some aspects of the traditional model of coercion, which continues to be perceived as effective under certain times and for certain spaces. We find that the resultant blending of the two models is heavily influenced by individual chefs’ personal perceptions of what care should be. This variation, we argue, comes from the not-yet-institutionalized nature of the care approach, whereby meanings become localized to the individual rather than across a field. Our qualitative data also reveals an intermediary phase in this process of change, whereby actors renegotiate the rules of the game through their choices of which aspects of old and new managerial ideologies to blend. |

VC expectations and returns |
| 講演者 | 高橋 秀徳 氏（神戸大学 経済経営研究所 准教授） |
| 概要 |
This study examines venture capitalists’ (VCs’) ability to forecast startup outcomes. Using proprietary data, we analyze the relationship between VC expectations and realized investment returns. We find that, although VCs’ return expectations are not associated with realized returns, their expectations regarding success probability and time to exit are informative. These results are robust to several alternative explanations, including downside risk and post-investment value-added activities. |

| テーマ | When Digitalization Doesn’t Help: Behavioral and Organizational Barriers to Patient-Facing Technology in Hospitals |
| 講演者 | Siliang Tong 氏 (Assistant Professor, Nanyang Technological University) |
| 概要 | Hospitals worldwide are increasingly adopting patient-facing digital technologies to improve operational efficiency and patient experience. Yet, rigorous causal evidence on their real-world effectiveness remains limited. We conducted a large-scale randomized field experiment with a major public hospital system in China to evaluate a digital navigation system designed to guide patients through complex outpatient workflows. Over a three-month period, the system was deployed to nearly one million patients, spanning 1.7 million outpatient visits. Contrary to expectations, we find no significant reduction in total visit duration. Further analyses reveal that these null effects are driven by two factors: extremely low patient adoption (3.2%) of the digital navigation system and the system’s inability to address core operational bottlenecks, such as limited physician capacity and rigid scheduling, as reflected by unchanged stage-to-stage time intervals within the outpatient process. These findings underscore how behavioral frictions and institutional constraints can undermine the intended benefit of patient-facing digital technologies, highlighting the need for integrated design strategies that align AI technologies with patient behavior, clinical workflows, and organizational processes. |

| テーマ | Implications of Unethical Pro-Social Behavio |
| 講演者 | Elizabeth Umphress 氏（Professor, Foster School of Business, University of Washington） |
| 概要 | In my research, I examine unethical behavior in organizations, with a particular focus on unethical prosocial behavior — acts intended to help, rather than harm, one’s organization or workgroup. In this talk, I will share research from this stream of work, highlighting why people engage in unethical prosocial behavior and what the consequences may be for work relationships and performance. |

Agency Frictions and Underwriting Compensation : Evidence From Japanese Initial Public Offerings |
| 講演者 | 蔡 越 氏（新潟県立大学 国際経済学部 講師） |
| 概要 | This paper quantifies the monetary value of agency frictions in Japanese IPO underwriting by estimating a structural principal-agent model using data from 2000 to 2022. It reveals that information rents and moral hazard significantly inflate compensation, acting as a rational insurance premium against the massive potential losses associated with underwriter shirking. Additionally, the analysis provides structural evidence supporting the universal banking hypothesis, showing that bank-affiliated underwriters face substantially lower effort costs compared to independent firms. |

| テーマ | Cloaked in Data: How Creative Brokers Overcome Data Resistance in Media Format Development |
| 講演者 | Joris Ebbers 氏（Full Professor, Entrepreneurship and Innovation, Luiss Business School） |
| 概要 | In the creative industries, big data and analytics have the potential to create insights into audience behavior and technological, cultural or content trends, offering new possibilities for rationally informing creative decisions. Yet our study of a data-rich media company known for producing internationally acclaimed formats reveals a striking contradiction: despite its strategic commitment to data-driven creativity and data’s potential to support idea generation and evaluation, data was routinely resisted by both creators and managers. This empirical surprise prompted an abductive inquiry into how data and creativity coexist in practice. Drawing on a 26-month qualitative study, we find that creators and managers resisted data because they perceived data as uninspiring, unreliable, or unconvincing in creative work. Instead, we reveal how creative brokers—who operate at the intersection of idea generation and evaluation—perform strategic work to overcome data resistance through a patterned, time-sensitive repertoire of inspiring, guiding, and legitimizing tactics. These tactics combine into three temporal pathways through which brokers render data meaningful without provoking resistance. Our findings reveal how data becomes workable in creative organizations through the strategic work of creative brokers, thereby extending brokerage theory and recasting data as a processual mechanism through which brokers can reconcile intuition-rationality tensions. |

| テーマ | Mandatory vs voluntary disclosure in the dynamic market for lemons. |
| 講演者 | Cyrus Aghamolla 氏（Rice University, Jones Graduate School of Business, Associate Professor of Accounting） |
| 概要 | We consider a dynamic adverse selection setting where a privately informed seller can choose to reveal or withhold past trade information to privately informed buyers. Buyers naturally receive less information when the seller can strategically withhold negative news relative to a setting where current buyers always observe the seller’s history of trade, i.e., mandatory disclosure. Despite the informational disadvantage, we find that strategic disclosure by the seller can be welfare-increasing relative to
mandatory disclosure, under which past trade is always disclosed. This occurs because voluntary disclosure attenuates the seller’s incentive to engage in destructive signaling and can lead to more efficient trade. Our model of repeated trade has applications to financial markets, particularly over-the-counter markets. Various OTC markets have been subject to increased post-trade transparency regulations in recent years, including a number of debt securities markets through TRACE, the European bond market through MiFID II, and the municipal bond market through MSRB Rule G-14. The empirical literature examining the impacts of these regulations has been mixed, with studies generally documenting both positive and negative effects of increased transparency depending on factors such as liquidity or yield of the asset. Our setting sheds light on possible improvements to transparency regulations, where permitting voluntary disclosure of past trade for certain asset types can improve trade frequency and welfare. In particular, when interpreting parameters of our model in the context of the OTC bond market, our results imply that voluntary disclosure can be advantageous relative to mandatory disclosure when adverse selection frictions are not too severe for high- and low-inventory cost bonds. |
