Evolution and Networks

Research Statement

Bounded rationality plays an important role in modern economics. This long-standing research line, which involves a fair number of different collaborators, deals with its modelling and consequences. The basic setting involves the analysis of stochastic dynamics in discrete time where players recurrently interact in a given strategic situation of interest (a game). It relies on the analysis of stochastic behavioral rules

  • Alós-Ferrer and Netzer (2010) provide analytical tools and first results for a particularly interesting dynamics which had previously eluded general analysis: the logit-response dynamics.
  • A number of works (Alós-Ferrer 2004, 2008; Alós-Ferrer and Shi, forthcoming) have studied the role of memory for equilibrium (and non-equilibrium) when players employ imitation rules.
  • In collaboration with Simon Weidenholzer (University of Essex), one line of work (Alós-Ferrer and Weidenholzer 2006, 2007, 2008, 2010) studies equilibrium selection on games played in networks.
