Power law in firms bankruptcy

Abstract: We consider the scaling behaviors for fluctuations of the number of Korean firms bankrupted in the period from August 1 2002 to October 28 2003. We observe a power law for the distribution of the number of the bankrupted firms. The Pareto exponent is close to unity. We also consider the daily increments of the number of firms bankrupted. The probability distribution of the daily increments for the firms bankrupted follows the Gaussian distribution in central part and has a fat tail. The tail parts of the proba… Show more

“…Zipf's law is universal rule followed by many natural and social systems (see e.g. Axtell, 2001;Bak, 1996;Batty, 2006;Gabaix, 1999a;Gabaix, 1999b;Hernando et al, 2009;Hong et al, 2007;Jiang and Jia, 2011;Shao et al, 2011;Stanley et al, 1995). This suggests that urban evolution follows the general laws of nature under certain condition.…”

“…Country Events Athletes Cost, billion USD Table 5: Events that follow power-law distributions and the law of regression to the tail, with alpha-values. The lower the alphavalue, the fatter the tail and the higher the risk for extreme values Type of event Alpha Earthquakes (intensity as Richter Scale maximum peak, Clauset et al 2006) 0.6 Cybercrime (financial loss, Maillart and Sornette 2010) 0.6 Wars (number of battle deaths per capita, Newman 2005) 0.7 IT procurement (percentage cost overrun, Flyvbjerg et al in progress) 0.9 Bankruptcies (percentage of firms per year per industry, Hong et al 2007) 1.1 Floods (volume of water, Malamud and Turcotte, 2006) 1.1 Forest fires (size of area affected, Clauset et al 2009) 1.2 Olympic Games (percentage cost overrun, present study)…”

“…Empirical data of several stochastic processes from distinct areas have been analyzed in literature, from financial time series [1][2][3] to heartbeat dynamics [4] and others. Of particular interest is the field of econophysics, which has attracted widespread attention in recent years [5][6][7][8][9][10][11][12]. This Letter focuses on the statistical behavior of financial time series.…”
