(31) will both gain from trade if, in the absence of trade, they have different relative costs for producing the same goods. Even if one country is more efficient in the production of all goods
(32) the other, both countries will still gain by trading with each other, as
(33) as they have different relative efficiencies.
For example,

(35) 6 per hour, and a worker in a country with less machinery can produce
(36) 2 shoes or 4 shirts in an hour, each country can gain from trade because their internal trade-offs between shoes and shirts are
(37) The less-efficient country has a comparative ad vantage in shirts, so it
(38) it more efficient to produce shirts and trade them to the more-efficient country for shoes.
