    "abstract": "We review the basic kinetic wealth-exchange models of Angle [J. Angle, Social\nForces 65 (1986) 293; J. Math. Sociol. 26 (2002) 217], Bennati [E. Bennati,\nRivista Internazionale di Scienze Economiche e Commerciali 35 (1988) 735],\nChakraborti and Chakrabarti [A. Chakraborti, B. K. Chakrabarti, Eur. Phys. J. B\n17 (2000) 167], and of Dragulescu and Yakovenko [A. Dragulescu, V. M.\nYakovenko, Eur. Phys. J. B 17 (2000) 723]. Analytical fitting forms for the\nequilibrium wealth distributions are proposed. The influence of heterogeneity\nis investigated, the appearance of the fat tail in the wealth distribution and\nthe relaxation to equilibrium are discussed. A unified reformulation of the\nmodels considered is suggested.",
