Familiarity Facilitates Adoption: Evidence from Electric Vehicles
with Ruozi Song (Last update: November 2022) NEW PAPER!
An Electric Vehicle (EV)-based ridesharing program in Los Angeles led to an increase in EV purchases, despite being a direct substitute to car ownership. We argue information explains it.
Learning versus Unlearning: An Experiment on Retractions
with Duarte Gonçalves and Jack Willis (Last update: September 2022) New Version!
We conduct an experiment on belief updating and document that subjects under-react to information when it is in the form of a retraction.
Coasian Dynamics under Informational Robustness
with Xiaosheng Mu (Last update: April 2022)
We propose an approach to study informationally robust dynamic pricing when the seller lacks commitment.
Algorithm Games and Rational Play with Strategic Inference
with In-Koo Cho (Last update: November 2021)
We exhibit an algorithm which ensures that agents play a Bayesian best reply (approximately).
Bounded Rationality
Evolutionarily Stable (Mis)specifications: Theory and Applications
with Kevin He (Last update: August 2022) (New version!) Presented @ EC '21
We introduce a selection criterion on behavioral biases in environments with learning, and show that it need not select for a bias-free worldview in some common applications.
Learning Underspecified Models
with In-Koo Cho (Last update: July 2022) (New Version!)
A monopolist can ensure an optimal price is used in the long run by designing an algorithm that assumes a linear demand curve, even if demand is quite nonlinear.
Researcher Incentives
Research Registries and the Credibility Crisis: An Empirical and Theoretical Investigation
with Eliot Abrams and John A. List (Last update: September 2021) R&R @ JEEA
We empirically study registries, focusing mostly (but not exclusively) on the AEA RCT Registry, and theoretically discuss issues related to incentives behind registration. The Mathematica notebook referenced in the Appendix can be found here.

Hypothetical Beliefs Identify Information
(Last update: May 2021) R&R @ JET
I demonstrate how to recover a decisionmaker's information structure from posterior beliefs over states, together with posterior beliefs that each signal could be observed. In the process, I make new observations on the geometric structure of information.
Iterative Weak Learnability and Multi-Class AdaBoost
with In-Koo Cho and Cheng Ding (Last update: January 2021) Rejected with encouragement to resubmit @ JMLR
We propose a classification algorithm with generalizes AdaBoost to a multi-class, which requires an intuitive and simple to check condition to be valid.
