How do I simulate a supply-demand market?

Open this page and use the live Lorenz & Gini tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.

Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.

Can I use my own numbers?

Absolutely — every input is adjustable, and with data import you can drive a supply-demand market from your own measurements.

Inequality level

The Lorenz curve plots the cumulative share of income against the cumulative share of population, from poorest to richest. Perfect equality is the diagonal; the more the curve bows below it, the more unequal the distribution. The Gini coefficient is twice the area between them — 0 is total equality, 1 is one person owning everything.

Governing equation

G = 1 - 2 \int_{0}^{1} L (p) d p = \frac{A}{A + B} = 0.628

Reading this result: High inequality (Gini 0.628): the curve bows far under the diagonal and the richest 10% capture 37% of all income.

About this simulation

The full Lorenz & Gini tool models a supply-demand market with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
