Elias Tsakas

Welcome to my homepage. I was born in Athens, and grew up in Patras, which is located on the west coast of Greece.

I am an Associate Professor in the Department of Microeconomics and Public Economics (MPE) and PhD Director within the Graduate School of Business and Economics (GSBE) at Maastricht University.

I serve as an Associate Editor in the Journal of Economic Behavior and Organization, and Coordinating Editor in Theory and Decision.

My research expertise lies on Game Theory, Decision Theory and Behavioral Economics. My current research focuses on the relationship among beliefs, information and behavior (e.g., how to measure beliefs, how beliefs are affected by information, how beliefs affect behavior, etc). I am also working on interesting applications within political science and sports. In the past, I have also worked on cooperation, risk preferences, epistemic game theory and evolutionary game theory, and occasionally on interesting mathematical problems within other fields.

My Erdös Number is (at most) 3. I do not have an Erdös-Bacon Number yet, but some day I would like to acquire one.
