GTEMO — Experiment Analysis

Pre-play communication and coordination in strategic games

1 Overview

This site collects the statistical analyses of the GTEMO experiment, which studies the role of pre-play communication in strategic coordination between same-sex dyads across four games:

Game	Type	Dyads	Equilibria
BS — Battle of Sexes	Coordination with asymmetric preferences	16	2 pure Nash
MP — Matching Pennies	Zero-sum game	15	Mixed only
PD — Prisoner’s Dilemma	Cooperative dilemma	14	1 dominant Nash
SH — Stag Hunt	Risk/Pareto coordination	16	2 pure Nash

Experimental design: between-subjects · same-sex dyads · roles P1 (LEEN) / P2 (CoCoLab)
