摘要：
We show, analytically and numerically, that wealth distribution in the Bouchaud-Mezard network model of the economy is described by a three-parameter generalized inverse gamma distribution. In the mean-field limit of a network with any two agents linked, it reduces to the inverse gamma distribution. (C) 2013 Elsevier B.V. All rights reserved.
