Staff profile

Diego Marino Fages is an Assistant Professor in the Economics Department. He completed his PhD from the University of Nottingham. He also obtained an MA from Duke University and from Universidad de San Andres. His research uses experimental and observational data to study culture, social preferences and social norms.

Diego’s current research relies on survey data to study how migrants assimilate culturally towards the locals. He also uses experimental methods to study how group sizes affect cooperation in public good games.

In more recent projects he is studying how the results of presidential elections can affect the prevailing social norms in a country (using data from Twitter) and exploring k-level thinking in Beauty Contest Games (using online experiments).
