  • Delli Gatti, Domenico; Di Guilmi, Corrado; Gaffeo, Edoardo; Gallegati, Mauro (Elsevier Science BV, 2004)
    Dynamical systems with components whose sizes evolve according to multiplicative stochastic rules have been recently combined with entry and exit processes. We show that the assumptions usually made in modeling exits are ...
  • Delli Gatti, Domenico; Di Guilmi, Corrado; Gaffeo, Edoardo; Gallegati, Mauro; Giulioni, Gianfranco; Palestrini, Antonio (World Scientific, 2004)
    Power law behavior is an emerging property of many economic models. In this paper we emphasize the fact that power law distributions are persistent but not time invariant. In fact, the scale and shape of the firms' size ...
  • Di Guilmi, Corrado; Gaffeo, Edoardo; Gallegati, Mauro (Elsevier Science BV, 2004)
    We study the size distribution of business cycles phases, that is expansions and contractions, for a sample of 16 industrialized countries over 120 years. We find that the best-fitting distribution for both expansions and ...
  • Delli Gatti, Domenico; Di Guilmi, Corrado; Gallegati, Mauro; Gaffeo, Edoardo; Giulioni, Gianfranco; Palestrini, Antonio (World Scientific, 2008)
    The practice of detecting power laws and scaling behaviors in economics and finance has gained momentum in the last few years, due to the increased use of concepts and methods first developed in statistical physics. Some ...
