Working Papers

Current
When the Buyer Is a Machine: The Diagnosticity-Exploration Tradeoff in Agentic Commerce Read more
with D. Shin & S. P. Han · In preparation for Information Systems Research
• Built a sandboxed e-commerce environment and collected roughly 23,000 agent purchases across commercial LLM agents, with attribute-matched fictional brands
• Found that agents open only one or two of eight candidates before deciding, and that aggregated social proof moves them while scarcity and urgency do not
• Accepted for presentation at ICIS 2026 (Lisbon) and INFORMS CIST 2026 (San Francisco)
Current
Regulating AI-Generated Content: When Do Restrictions Spark or Stifle Community Dynamics Read more
with J. Shin, D. Shin, & W. Oh · In preparation for MIS Quarterly
• Examined AI content bans across 743 Reddit communities using staggered difference-in-differences
• Found opposing effects by community type: participation fell in information communities and rose in creative ones
• Best Student Paper Award, KMIS 2025; Best Student Paper Nominee, WISE 2025
Current
The Summarization Paradox: AI Summarization and Creator Multimodal Content Strategies Read more
with S. Kim & D. Shin · In preparation for Journal of the Association for Information Systems
• Studying how creators adapted after Google Maps introduced Gemini-based review summaries
• Because the summarizer reads text but not images, creators posted fewer images and left rating-only reviews
• Presented at the KrAIS Summer Workshop, 2026
Current
Predicting Spatial Choice Without Historical Data: A Theory-Guided LLM Simulation Framework Read more
with Y. Yu & D. Shin · In preparation for Journal of Management Information Systems
• Developed the Person-Environment-Situation (P.E.S.) framework so that behavioral theory, not history, constrains LLM-based prediction
• Validated against 1.1M real check-in records with the later period held out, addressing the cold-start setting where no training data exists
• Earlier version published at CIKM 2025

Work in Progress

Ongoing
Consumer-side versus seller-side shopping agents
with J. Lee, Y. Lee, M. Kim, & D. Shin · Under review
• Asking whether who an agent works for changes how much buying authority people are willing to hand it
• Title withheld while the paper is under anonymous review
Ongoing
Using synthetic persona populations to predict real purchases
with M. Kwak & D. Shin · Under review
• Asking whether an outside population of generated profiles can stand in for the parts of a shopper's situation that transaction records never capture
• Title withheld while the paper is under anonymous review
