  We construct a model of wealth distribution, based on an interactive
multiplicative stochastic process on static complex networks. Through numerical
simulations we show that a decrease in the number of links discourages equality
in wealth distribution, while the rewiring of links in small-world networks
encourages it. Inequal distributions obey log-normal distributions, which are
produced by wealth clustering. The rewiring of links breaks the wealth
clustering and makes wealth obey the mean field type (power law) distributions.
A mechanism that explains the appearance of log-normal distributions with a
power law tail is proposed.
