Symmetric Markovian Games of Commons with Potentially Sustainable Endogenous Growth, with Christos Koulovatianos, - Symmetric Markovian differential games with a linear accumulation constraint that address commons problems admit an exact (interior) solution because of the Hamilton-Jacobi-Bellman equation of each player can be reduced into a form of the Lagrange-d'Alembert differential equation. Dynamic Games and Applications (2021) 11:54–83. It also appears as SSRN.
Populism and Polarization in Social Media Without Fake News: the Vicious Circle of Biases, Beliefs, and Network Homophily, with Christos Koulovatianos, January 2020- Internet has made people with similar individual biases, such as confirmation bias or assimilation bias, meeting faster, and this key feature, combined with peer influence and limited information produces polarization network dynamics and a gradual downgrading of expert opinion on complicated issues, even without fake news. Slides. Also appearing as SSRN.
Can a social planner manipulate network dynamics and solve coordination problems? April 2020 - In this paper I build an algorithm of network dynamics with decision-making under incomplete information, seeking to understand if a social planner can solve coordination problems among agents and decrease the weight of individual biases, such as confirmation bias or assimilation bias. I explore if a "Liberal Social Planner", who influences the process of random invitations of network members to make new friends, but who then leaves people free to choose whom to make a friend, can make people more pragmatist. My results have potential applications for the management of social media platforms by the owners of these platforms. Slides
