Wealth distribution in modern societies: Collected data and a master equation approach

A mean-field like stochastic evolution equation with growth and reset terms (LGGR model) is used to model wealth distribution in modern societies. The stationary solution of the leads an analytical form for density function that successful describing observed data all categories. In limit high values proposed has accepted Tsallis-Pareto shape. Our results are agreement predictions earlier approach based on a exchange process.
