Suppose Alpha produced 6 tons of pearls and 15 tons of pineapples and Beta produced 30 tons of pearls and 8 tons of pineapples before they decided to trade. Assume that the two islands agree to specialize and trade and that the terms of trade will be 1 ton of pineapples for 1 ton of pearls. Trade soon results in an exchange of 10 tons of pineapples for 10 tons of pearls. Assume that the two countries specialize just enough to maintain their consumption of the item they export.
