In the city of Rome economic and territorial polarizations increased between centre and peripheral belts, paralleling suburban sprawl. Electoral data 2005-2011 highlight sharp political polarization, too. Left-wing candidates prevail where social centrality exists, i.e. in dense zones with...

Despite widespread support from policy makers, funding agencies, and scientific journals, academic researchers rarely make their research data available to others. At the same time, data sharing in research is attributed a vast potential for scientific progress. It allows the reproducibility of...

We study the interplay between leading-by-example and group identity in a three-person sequential voluntary contributions game experiment. A common identity between the leader and her two followers is beneficial for cooperation: average contributions are more than 30% higher than in a benchmark...

Geography and social links shape economic interactions. In industries, schools, and markets, the entire network determines outcomes. This paper analyzes a large class of games and obtains a striking result. Equilibria depend on a single network measure: the lowest eigenvalue. This paper is the...

In city districts in Rome, social and economic inequalities between centre and peripheral belts have been increasing over the last years, in parallel to the on-going suburban sprawl. Electoral data from 2000 to 2013 highlight sharp political polarization too. Votes for left-wing (right-wing)...
