History of economic thought, in playable models

Every economic theory is a claim about how things flow: grain, coin, labour, debt, ideas. Here each one is a small model you can play. Move its two Levers and watch the outcome change.

These are teaching models: each keeps only the theory's core loop and leaves out everything else a real economy has.

Ancient

Before 500 CE

Temples, kings and granaries: the first economies ran on stored grain, credit and tribute.

Medieval

500 to 1500

Faith, land and guilds set the rules for prices, interest and work.

Early modern

1500 to 1776

Silver from the Americas, trade wars and the first statistics turned the economy into a matter of state.

Classical

1776 to 1870

Markets, specialisation and trade as engines of wealth, and the limits of land and population.

Marxian

1840 to 1930

Labour, capital and the socialist debate over who keeps the surplus and who plans.

Keynesian

1930 to 1970

Demand, cycles and growth after the Great Depression.

Post-war

1970 to 2005

Expectations, markets, commons and behaviour: the economy re-examined.
