| Outline of Final Research Achievements |
Several papers were published that explore the boundary between collaborative choice and individualistic choice. These included "Watercooler chat, organizational structure and corporate culture" (Games & Economic Behavior), which explored the success and failure of different choice rules in the workplace, "Agency Equilibrium" (Games) which examined uncertain environments, "Collaboration leads to cooperation on sparse networks" (PLOS-Computational Biology) which examined cooperation, "Agency, potential and contagion" (Games & Economic Behavior) which related choice rules to potential functions. I further studied "Risk attitudes and risk dominance in the long run" (Games & Economic Behavior) and proved some important results on how choice rules can interact and be aggregated in populations ("Conventions under heterogeneous choice rules" - R&R at Review of Economic Studies). Further, I travelled extensively and pursued the project with the help of several international collaborators.

| Academic Significance and Societal Importance of the Research Achievements |
I examined the relationship between how people make decisions individually and collectively and how it affects behavior in and out of the workplace. I further examined how societies can end up converging to common outcomes even if people behave very differently to one another.
