Assume that by devoting all of its resources to the production of $x,$ nation Alpha can produce $40$ units of $x.$ By devoting all of its resources to $Y,$ Alpha can produce $60$ Y $.$ Comparable figures for nation Beta are $60$ X and $40$ Y $.$ We can conclude that

there is no basis for mutually beneficial specialization and trade.

Alpha should speciatize in $x$ and Bctati.Y

the terms of trade will be $3$ equals ir
