Presets
David Ricardo's great insight: even if one country is worse at making everything, both still gain from trade. Each should specialize in the good it gives up the least to produce — its comparative advantage — measured by the slope of its production-possibility frontier. Trade then lets both consume beyond their own frontiers.
Data Inspector
A opp. cost (wine)0.50 cloth
B opp. cost (wine)2.00 cloth
A should makewine
B should makecloth
Governing equation
Reading this result: Country A gives up 0.50 cloth per wine versus B at 2.00, so A specializes in wine and B in cloth — trade then lets both consume beyond their own frontiers.
