Figure 6
The probability density of the log growth rate of firm sales for different cases of parameters. The plot shows the case of \(10^3\le S\) in the simulation as “All” as in Fig. 5f as well as the fitting function of Fig. 5e for reference. The non-symmetric cases of merger and split, \((p_m,p_s,p_{pa})=(0.37,0,0.02)\) is also plotted as green lines and marks. It can be observed that the negative side shrinks and the symmetry breaks. The case where partial annihilation is suppressed, \((p_m,p_s,p_{pa})=(0.37,0.37,0)\) is shown by the light blue lines and marks. The density in the negative-side tail is smaller than in the partial annihilation case (\(p_{pa}=0.02\)).
