Without trade, Jake consumes 20 pounds of green beans and 80 pounds of corn, and Jane consumes 40 pounds of green beans and 40 pounds of corn. If the terms of trade are 1 pound of green beans for 3 pounds of corn, and Jake sells Jane 72 pounds of corn, then the gains from trade for Jake are pounds of green beans and pounds of corn with trade and specialization.

then the gains from trade for Jake are   4   pounds of green beans and 8   pounds of corn with trade and specialization.

Jake gains with trade:

gives 72 pounds of corns in exchange of 72 /3 = 24 pounds of greeen bean

as it currently consumes the gain from trade will be of 4 units of green bean

to produce this units it will put the entire of his effort to corn and Jake can produce 4 punds of corn per pound of green beans

20 x 4 = 80 additional pounds of corst

less the 72 traded there is a gain of 8 more pounds
