Initially, suppose Bellissima uses 1 million hours of labor to produce rye and 3 million hours to produce jeans, while Dolorium uses 3 million hours of labor to produce rye and 1 million hours to produce jeans. Consequently, Dolorium produces 32 million pairs of jeans and 24 million bushels of rye, and Bellissima produces 72 million pairs of jeans and 12 million bushels of rye. Assume there are no other countries willing to trade goods, so in the absence of trade between these two countries, each country consumes the amount of rye and jeans it produces.
Dolorium's opportunity cost of producing one bushel of rye is_________ of jeans, and Bellissima's opportunity cost of producing one bushel of rye is _______ of jeans. Therefore, ________ has a comparative advantage in the production of rye and ________ has a comparative advantage in the production of jeans.
