Pareto compiled his teaching notes into a book, entitled Course in Political Economy.2 This quantitative book built upon his college thesis by proposing a general equilibrium theory, namely, the distribution of inputs relative to outputs.

The 80/20 rule summarizes the equilibrium point of the Pareto distribution.
