  • 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 ...
  • 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 ...
  • Firms' size distribution and growth rates as determinants of business fluctuations 
    Delli Gatti Domenico; Di Guilmi Corrado; Gaffeo Edoardo; Gallegati Mauro; Giulioni Gianfranco; Palestrini Antonio (Springer, 2005)
    NA
  • International evidence on business cycle magnitude dependence 
    Di Guilmi Corrado; Gaffeo Edoardo; Gallegati Mauro; Palestrini Antonio (Euro-American Association of Economic Development Studies, 2005)
    Are expansions and recessions more likely to end as their magnitude increases? In this paper we apply parametric hazard models to investigate this issue in a sample of 16 countries from 1881 to 2000. For the total sample ...
  • A New Approach to Business Fluctuations: Heterogeneous Interacting Agents, Scaling Laws and Financial Fragility 
    Delli Gatti Domenico; Di Guilmi Corrado; Gaffeo Edoardo; Giulioni Gianfranco; Gallegati Mauro; Palestrini Antonio (Elsevier B.V., 2005)
    In this paper, we discuss a scaling approach to business fluctuations. Our starting point consists in recognizing that concepts and methods derived from physics have allowed economists to (re)discover a set of stylized ...
  • Power Law Scaling in World Income Distribution 
    Di Guilmi Corrado; Gaffeo Edoardo; Gallegati Mauro (Vanberbilt University, 2003)
    We show that over the period 1960-1997, the range comprised between the 30th and the 85th percentiles of the world income distribution expressed in terms of GDP per capita invariably scales down as a Pareto distribution. ...
  • 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 ...
