Economics Interactives

Load real GDP, population and Gini figures for seven countries — or set your own — and watch the Lorenz curve bow away from perfect equality, then see exactly how much income each of ten population deciles receives, in local currency or US dollars.

Toggle between industry pairs, drag two sliders to test any combination of output, and see whether it's efficient, inefficient or currently unobtainable — then shift the curve with economic growth, development, and industry-specific shocks.

Simulate demand and supply shifts for the NZ Dollar ($NZ vs $USD), explore floating vs fixed rate regimes, reserve interventions, and macroeconomic impacts.
