Assume a Ricardian model with two countries, Home and Foreign,
that both produce coffee and tea. Home has 600 units of labor (L)
available. Home’s unit labor requirement in the production of
coffee is aLC = 4, while in the production of tea it is
aLT = 3. Foreign has 800 units of labor (L*)
available. Foreign’s unit labor requirement in the production of
coffee is a*LC = 2, while in the production
of tea it is a*LT = 1....
