A few years ago, Katie Cronin, Dan Acheson, Penélope Hernández and myself showed that when a hierarchy is present in a human group, such that rewards from collaborative work are distributed according to that hierarchy, cooperation decreases (this paper). Now, again with Katie, but this...
In a research using ideas from behavioral sciences and game theory, we have worked along with the Federació de Salut Mental de Catalunya and a researcher team from Open Systems at Universitat de Barcelona and Universitat Rovira i Virgili to analyze the features of the...
Today, my perspective paper on experiments on human cooperation and its relation to theoretical models is out, and can be found here. I believe that quoting the abstract is the easiest way to convey what it is about: In recent years, many physicists have used evolutionary...
I have a new paper out presenting the results of what, to my knowledge, are the first experiments on Ultimatum games on networks, resulting from a very nice and enjoyable collaboration with Boyu Zhang and Wenxu Wang at Beijing Normal University. We find that status equality,...
The data from our paper "Humans display a reduced set of consistent behavioral phenotypes in dyadic games", by Julia Poncela-Casasnovas, Mario Gutiérrez-Roig, Carlos Gracia-Lázaro, Julian Vicens, Jesús Gómez-Gardeñes, Josep Perelló, Yamir Moreno, Jordi Duch and myself, have been made freely available thanks to the efforts of Josep....
Along with Mattia Mazzoli, we have studied the problem of coordination on complex networks when there are two types of agents and they prefer different options to coordinate. We predict that mixed equilibria, in which a sizable fraction of players play the action they prefer...
A few months ago I published a paper jointly with Pablo Brañas-Garza and Ismael Rodríguez Lara showing experimental evidence that humans expect generosity from others (see details here). Now María Pereda joins the team to study the issue from the modeling viewpoint. In a new paper,...
I am proud to announce a new paper I have co-authored with my friend Federico Pablo-Martí, from Universidad de Alcalá, Madrid, Spain. The paper presents results on how transportation networks evolve when they are not optimized once and for all but, on the contrary, different...
This week we are celebrating the 10th anniversary of IFISC, the Institute for the Physics of Complex Systems at Mallorca, and also the 65th birthday of its director, Maxi San Miguel. Congratulations to both of them! I will be a panelist in the Round Table...
This week, I am visiting the University of Utrecht as a Visitor Professor sponsored by the Focus Area on Complex Systems. I am presenting a seminar on "Social Physics: Understanding Complex Socio-Technical Systems" for the Focus Area. I will be hosted by the Sociology Department...
