Rational Inattention and Endogenous Volatility: A Large Deviation Approach (with Takashi Ui) [30-min Slides]

• Does rational inattention create endogenous volatility in large economies (#agents → ∞)?

• This paper subsumes a part of my JMP.

Recursive Rational Inattention Is Entropic (to be joint work with Henrique De Oliveira) [Slides]

• What kind of information cost makes the value function recursive?

Rational Inattention in Games [JMP version, JMP slides]

• Which equilibrium is robust to a small misspecification of players' cost of information acquisition?

• This paper is subsumed by the following two papers:

  • • On the robustness of equilibria to endogenous information acquisition.

    • On a "physics" approach to economic models (to be joint work with Takashi Ui).

Bargaining and Information Acquisition (with Kalyan Chatterjee and Miaomiao Dong)

• Does a buyer with cheap access to information get a surplus from a seller with full bargaining power?

Communication, Censorship, and Coordination

• Does communication with or without censorship help players coordinate?

Enforcement against Organized Crime Increases Organized Fraud (with Takuma Kamada)
