A country produces only commodity 1 and commodity 2 using capital (K) and
Labor (L) as inputs. Assume that the production of commodity 1 uses 10 units of
capital for each worker, so that K1 =10L1 , while the production of commodity 2
uses 2 units of capital for each worker, so that K2 =2L2 . The total supply of
capital is 400 units and the total supply of labor is 100 units.
(a) Determine the amount of both inputs of production, that is, capital and labor,
used in each commodity and the output levels.
(b) Now assume that the number of workers increases to 140 due to immigration,
keeping total capital fixed at 400. Solve for the amount of capital and labor in
used in each commodity and for the output levels. Relate your findings in (a) and
(b) to a theoretical result of the Standard Trade Theory.
