Edgeworth box of the Ricardian model
This widget plots the Edgeworth box of the Ricardian model of trade with two goods and two countries.
It allows you to change the size of the countries, technologies of production, as well as the consumer preferences and observe the consequent changes in model equilibria.
The widget shows the equilibria under autarky and free trade and illustrates the gains from trade.
