  • 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 ...
  • Do Pareto-Zipf and Gibrat Law Hold True? An Analysis with European Firms 
    Fujiwara Yoshi; Di Guilmi Corrado; Aoyama Hideaki; Gallegati Mauro; Souma Wataru (Elsevier Science BV, 2004)
    By employing exhaustive lists of large firms in European countries, we show that the upper-tail of the distribution of firm size can be fitted with a power-law (Pareto¿Zipf law), and that in this region the growth rate of ...
  • Empirical Results on the Size Distribution of Business Cycle Phases 
    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 ...
  • Gibrat and Pareto-Zipf revisited with European firms 
    Fujiwara Yoshi; Aoyama Hideaki; Di Guilmi Corrado; Souma Wataru; Gallegati Mauro (Elsevier Science BV, 2004)
    A firms growth and failure are the two sides of the same coin. This paper reports new phenomenological findings for firm size distribution and growth, and bankruptcy. This paper is based on [Y. Fujiwara et al., Physica A ...
  • Scaling Invariant Distributions of Firms' Exits in OECD Countries 
    Di Guilmi Corrado; Gallegati Mauro; Ormerod Paul (Elsevier Science BV, 2004)
    Self-similar models are largely used to describe the extinction rate of biological species. In this paper we analyse the extinction rate of firms in eight OECD countries. Firms are classified by industrial sectors and ...
  • 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 ...
