​​I am currently associate professor of economics at New York University Abu Dhabi. I am interested in building and testing models to better understand phenomena such as multilateral bargaining, contracting, and incentive provision in groups. I study the trade-off between productive and rent-seeking activities that might arise in human organizations and mechanisms to promote efficiency in such settings. Topics: Collective Decision-Making; Bargaining Games; Experimental Economics; Behavioral Economics; Industrial Organization; Experimental Political Economy.

I am the director of the Social Science Experimental Laboratory (SSEL) and director of the cluster of Experimental Social Science at NYU Abu Dhabi.

​New Tool: Communication Annotation Tool (CAT) using LLMs

(With David J. Cooper and Jeong Kyu Lee)

We are pleased to introduce the Communication Annotation Tool (CAT), a browser-based platform that helps experimental social scientists analyze free-form communication using large language models. CAT enables researchers to create flexible coding manuals, annotate messages or complete conversations using multiple LLMs, assess coding reliability, review problematic cases, and generate replication-ready datasets and documentation (all without programming or API expertise).

CAT is designed to make rigorous content analysis faster, more affordable, transparent, and reproducible. A guided tutorial and video are available on the CAT website. 

If you are wondering whether LLMs are reliable for coding communication content in experiments, we answer this methodological question here:​
