First They Came for the Others: A Theory of Divide-and-Conquer
Yeon-Koo Che, Jinyuqi Huang, Wooyoung Lim
Divide-and-conquer tactics often succeed not through mechanical coordination failures, but through inferential friction regarding an aggressor's underlying intent. When an attacker…
Learning Against Nature: Minimax Regret and the Price of Robustness
Yeon-Koo Che, Longjian Li, Tianling Luo
We study how a decision-maker (DM) learns from data of unknown quality to form robust, ''general-purpose'' posterior beliefs. We develop a framework for robust learning and belief…
Data-Driven Monitoring and Deterrence in a Changing Environment
Yeon-Koo Che, Jinwoo Kim, Konrad Mierendorff
We study a dynamic model in which a principal monitors agents based on historical data of infractions. This data informs when and at what intensity to monitor; the monitoring decis…
Optimal Queue Design
Yeon-Koo Che, Olivier Tercieux
We study the optimal method for rationing scarce resources through a queue system. The designer controls agents' entry into a queue and their exit, their service priority -- or que…
Prolonged Learning and Hasty Stopping: the Wald Problem with Ambiguity
Sarah Auster, Yeon-Koo Che, Konrad Mierendorff
This paper studies sequential information acquisition by an ambiguity-averse decision maker (DM), who decides how long to collect information before taking an irreversible action.…
Stable Matching with Mistaken Agents
Georgy Artemov, Yeon-Koo Che, YingHua He
Motivated by growing evidence of agents' mistakes in strategically simple environments, we propose a solution concept -- robust equilibrium -- that requires only an asymptotically…
Robustly Optimal Mechanisms for Selling Multiple Goods
Yeon-Koo Che, Weijie Zhong
We study robustly optimal mechanisms for selling multiple items. The seller maximizes revenue against a worst-case distribution of a buyer's valuations within a set of distribution…
"Near" Weighted Utilitarian Characterizations of Pareto Optima
Yeon-Koo Che, Jinwoo Kim, Fuhito Kojima +1
We characterize Pareto optimality via "near" weighted utilitarian welfare maximization. One characterization sequentially maximizes utilitarian welfare functions using a finite seq…
Bailout Stigma
Yeon-Koo Che, Chongwoo Choe, Keeyoung Rhee
We develop a model of bailout stigma where accepting a bailout signals a firm's balance-sheet weakness and worsens its funding prospect. To avoid stigma, high-quality firms either…
Statistical Discrimination in Ratings-Guided Markets
Yeon-Koo Che, Kyungmin Kim, Weijie Zhong
We study statistical discrimination of individuals based on payoff-irrelevant social identities in markets that utilize ratings and recommendations for social learning. Even though…
Keeping the Listener Engaged: a Dynamic Model of Bayesian Persuasion
Yeon-Koo Che, Kyungmin Kim, Konrad Mierendorff
We consider a dynamic model of Bayesian persuasion in which information takes time and is costly for the sender to generate and for the receiver to process, and neither player can…
Monotone Comparative Statics without Lattices
Yeon-Koo Che, Jinwoo Kim, Fuhito Kojima
The theory of Monotone Comparative Statics (MCS) has traditionally required a lattice structure, excluding certain multidimensional environments such as mixed-strategy games where…
Optimal Dynamic Allocation of Attention
Yeon-Koo Che, Konrad Mierendorff
We consider a decision maker (DM) who, before taking an action, seeks information by allocating her limited attention dynamically over different news sources that are biased toward…
