For some, the income distribution is the first example of a power law, empiric rule whereof an random variable reaches high values with a low probability and low values with a high probability. This article corroborates if the income distribution of the richest Colombians adjusts to a power law. Similarly, considering Yule´s process (1925), and in general, stochastic processes´ theory, a theoretical model, whose objective is to explain why income is distributed according to a power rule, is formulated. The essence of the model is that wealth presents an accumulative effects, therefore, at a higher income level, higher the probability of increasing it.

Keywords : inequality; power laws; Pareto´s law; stochastic processes; Yule´s process.
