Entrepreneurs, Chance, and the Deterministic Concentration of Wealth

Figure 2

Modeled wealth distribution.

In simulations with , % and all 100,000 individuals starting with wealth of 1 at time zero, the lower portion of the wealth distribution is represented by the blue line at time , the red line at time , and the black line at time . Circles indicate the median wealth and diamonds indicate the mean wealth. Note that mean wealth increases much faster than median wealth, while in this case the modal wealth, identified by the peaks of the curves, decreases. Over time, an increasing portion of the population has wealth greater than 20 units (0.01% of the population, 1%, and 18% at , 12, and 31, respectively), which is not depicted because it falls beyond the right boundary of the graph.
