Current Research

• The Structure of Bounded Reasoning

This research project asks what “bounded reasoning” really means. In particular, it develops an epistemic game-theoretic framework that distinguishes bounded reasoning driven by beliefs about others’ types from bounded reasoning driven by limits in higher-order reasoning. It aims to clarify what observed level-k behavior does (and does not) reveal about underlying reasoning structure.

Reasoning about Bounded Reasoning (with Gabriel Ziegler)

• Language, Reasoning, and Complexity

This project starts from a simple but under-explored idea: human beings reason through language. If so, epistemic and practical reasons should be modeled not only in terms of what is true or probable, but in terms of what can be expressed, derived, and justified within a formal language. This motivates a shift from purely semantic models toward syntactic and proof-theoretic representations of reasoning.

Measuring Information Burden: From Coalition-Based Reasoning to the Price System (May 30, 2026 ver) 

   This paper develops a proof-theoretic framework for asking and answering what kind and how much information is sufficient for decentralized decision-making, and uses it to show an informational inconsistency behind the Debreu-Scarf theorem: the core path to competitive equilibrium requires an informational burden that grows with the size of the economy, while competitive equilibrium itself does not.

• Great Power Politics and International Order

This project studies great-power politics through the lens of international order. More broadly, it asks how international orders form, how their governance and commitment structures evolve, when they are sustained or revised, and under what conditions a new order emerges. It also examines how these processes are shaped by the alignment choices of states and the institutional roles of international organizations.

Pecuniary Externality, Ideology and Sphere of Influence (with Tomoo Kikuchi and Lien Pham), accepted by European Journal of Political Economy (June 2026)

• Misinformation, Networks, and Political Behavior

This line of research studies belief formation and strategic behavior under distorted informational environments. I am interested in how misinformation and disinformation spread through social networks, how social pressure and strategic incentives shape individual reactions, and how these micro-level dynamics affect broader political and institutional outcomes.
