Date: 20 February 2026, Wednesday Time: 13.30 – 14.30 Place: MA-330 "Supply chain risk management: Sharing information and exploring uncertainty" by Stefan Minner Technical University of Munih Abstract  Different sources of uncertainty and local information present major challenges in logistics and supply chain coordination. Effective distributed data-driven learning and decision making requires a balance between proactive and reactive exploration and exploitation as well as uncertainty modeling in dynamically changing environments. We discuss cooperative and competitive coordination schemes, different information sources and fusion concepts, digital technologies and strategies for effective information sharing and learning, and economic frameworks for information valuation.  Bio Stefan Minner is a Full Professor for Logistics and Supply Chain Management at the School of Management, Technical University of Munich (TUM) and a core-member of the Munich Data Science…

Date: 18 February 2026, Wednesday Time: 10.30 – 11.30 Place: MA-330 "Monetary Policy Shocks: A New Hope — Large Language Models and Central Bank Communication” by Ruben Fernandez Fuertes Bocconi University Abstract  I develop a multi-agent LLM framework that processes Federal Reserve communications to construct narrative monetary policy surprises. By analyzing Beige Books and Minutes released before each FOMC meeting, the system generates conditional expectations that yield less noisy surprises than market-based measures. These surprises produce theoretically consistent impulse responses where contractionary shocks generate persistent disinflationary effects, and enable profitable yield curve trading strategies that outperform alternatives. By directly extracting expectations rather than cleaning surprises ex post, this approach demonstrates how multi-agent LLMs can implement narrative identification at scale without contamination in high-frequency measure. Bio Rubén Fernández-Fuertes is a financial…

Date: 11 February 2026, Wednesday Time: 10.30 – 11.30 Place: MA-330 "Inflation Expectations and Firms' Decisions in High Inflation” by Okan Akarsu Sabancı University Abstract  We conducted a survey of Turkish firms, using randomized treatments to provide varied information about inflation in a high-inflation environment. By matching the survey data with administrative firm-level data on employment, sales, credit, and foreign exchange transactions, we explore the impact of exogenous variations in inflation expectations on firms' behavior, borrowing decisions, and expectations. Our findings are summarized in seven facts: (i) information treatments are effective at generating exogenous variation in inflation expectations, even when inflation is high; (ii) the pass-through to firms' own price, wage, and cost expectations is strong, reaching up to 60%; (iii) firms adopt a supply-side interpretation of inflation—lower inflation expectations…

Date: 4 February 2026, Wednesday Time: 10.30 – 11.30 Place: MA-330 "The Pricing and Economic Impact of Legal Risk" by Dean Ryu Saïd Business School – Oxford Abstract  Legal risk is an inherent feature of markets, rooted in the institutions that enable economic activity, yet it remains difficult to measure across firms. This paper constructs a text-based measure of firm-level legal risk (LRISK) using earnings call transcripts. LRISK predicts class action lawsuits and spikes during periods of heightened legal incidents. A one standard deviation increase predicts a 3–7% decline in future investment and lowers firms’ reliance on debt, consistent with precautionary motives. Legal risk is positively priced, particularly after 2010, and varies across legal origins, reflecting institutional differences. Bio Dean Ryu is a Finance Ph.D. Candidate at Said Business School,…

Date: 30 January 2026, Friday Time: 13.30 – 14.30 Place: MA-330 "Breaching the Chinese Wall: Cross-Market Information Flow Following Financial Institution Mergers" by Ehsan Mahdikhani Stockholm School of Economics Abstract  How does access to private loan information affect institutional investors' equity returns? Exploiting mergers between asset managers and lenders as a plausibly exogenous shock to loan-side information access, we find that after gaining access institutional investors earn higher abnormal equity returns: within institutions, managers earn 3.1 pp higher annualized returns on stocks for which they have loan-side access than on their other holdings without such access, and across institutions trading the same stock, informed managers outperform equity-only peers by 1.7 pp annualized, consistent with debt positions conferring information unavailable to pure shareholders. Mechanism tests show larger gains when financial-reporting covenants…

Date: 28 January 2026, Wednesday Time: 10.30 – 11.30 Place: MA-330 "Why Do I Do What I Do? How Searching for Meaning at Work Can Facilitate the Spread of Unethical Conduct Through Organizations" by Marius Van Dijke RSM Abstract  Existing work has explained the trickling down of unethical leader behavior through organizations in terms of social learning or social exchange processes. We identify a key limitation of these explanations and propose a novel process to explain the trickling down of unethical leader behavior. We build on Baumeister’s (1991) account of meaning, which depicts it as a system of mental connections between objects and events. We propose that strongly (vs. weakly) searching for meaning at work strengthens trickle-down effects of unethical leadership from higher-level managers, via lower-level managers to employees. We…

Date: 19 January 2026, Monday Time: 10.30 – 11.30 Place: MA-330 " Digital Solutions to the Obesity Crisis: Evaluating the Impact of Online Grocery Delivery Services " by Alireza Golmohammadi Belk College of Business Abstract  Despite extensive efforts in developed nations to combat obesity, rates continue to rise, particularly in the U.S., with low-income populations being disproportionately affected. This study examines the potential of third-party online grocery delivery services (OGDS) to mitigate obesity. Utilizing a staggered difference-in-differences approach, we analyze the impact of OGDS’s entry on obesity rates. Our findings reveal that OGDS entry is associated with a significant reduction in obesity rates, averaging -.64%, which translates to an annual medical cost saving of $2.91 billion. However, the positive impact of OGDS entry is less pronounced in low-income areas, indicating…

Date: 07 January 2026, Wednesday Time:10.30 – 11.30 Place: MA-330 “Inclusive Exclusion: When Market Expansion Reinforces Exclusion” by Utku Ay University of Arizona Abstract  Firms often seek growth through inclusion, extending their brands to new consumer groups. Yet these initiatives frequently reproduce exclusionary structures rather than dismantle them. This study introduces inclusive exclusion, an empirically derived and theoretically grounded construct that explains how inclusionary marketing strategies can perform inclusion while sustaining exclusionary order. Drawing on an ethnographic investigation of football in Turkey, we identify three mechanisms of market participation that structure consumer inclusion and exclusion: consumer role assignment, consumption pathways, and infrastructural support. Inclusion emerges under conditions of role alignment, coherent pathways, and strong infrastructural support, which foster legitimate market participation. Conversely, when firms invite new consumers, but these mechanisms…
