1) Mentors and Recombinators: Multi-Dimensional Social Learning (download, presentation: pptx, pdf). Joint with Srinivas Arigapudi, Omer Edhan, Ziv Hellman. Revision requested at Theoretical Economics.
Idea: We study learning dynamics in which new agents learn how to play by combining traits from various successful incumbents.
2) Strategies in the repeated prisoner's dilemma: A cluster analysis (download, GitHub data and code). Joint with Itay Tubul.
Idea: We apply a new technique of cluster analysis to study which strategies are used in experiments of the infinitely repeated prisoner's dilemma.
3) Uniqueness of Inflection Points in Binomial Exceedance Function Compositions (GDrive download). Joint with Srinivas Arigapudi and Amnon Schreiber.
Idea: We show that compositions of binomial exceedance functions have unique inflection points, and discuss the interesting implications of this property.
Work in Progress:
1) Experimental observations on cooperation. Joint with Erik Mohlin & Matthew Embrey.
Idea: The experiment will test the key predictions of Heller & Mohlin (2018, ReStud) regarding the behavior in the prisoner's dilemma with random matching, where each agent can observe the opponent's behavior in a couple of past interactions.
2) Community Enforcement and Feuds (preliminary partial draft). Joint with Hillay Zmora and Ro’i Zultan.
Idea: Motivated by the frequent feuds in pre-modern Germany, we show that introducing public feuds to prisoner’s dilemma with random matching, can significantly enlarge the domain in which robust cooperation can be sustained.
