  • Bankruptcy as an Exit Mechanism for Systems with a Variable Number of Components 
    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 ...
  • Business Cycle Fluctuations and Firms - Size Distribution Dynamics 
    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 ...
  • Scaling laws in the macroeconomy 
    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 ...
