Question

There are 2 countries, D and F. There are 2 products X and Y. Each country has only a single input labor hours, Li, j, where i is D for Domestic or F for Foreign and j is either X for Good X use of the labor or Y for Good Y use of labor.

 

 

In country D:

  • XD = aD*LD, X
  • YD = bD*LD, Y
  • LD = LD, X + LD, Y

 

In country F:

  • XF = aF*LF, X
  • YF = bF*LF, Y
  • LF = LF, X + LF, Y


At the moment: aD = 0.25, bD = 0.5, LD = 32, aF = 0.8, bF = 0.4, LF = 40. Each country is operating in autarky and has determined to divide its labor force equal between the production of X and Y

Now the two countries open to trade. The Terms of Trade are set 1 unit of X for 1.5 units of Y. The countries exchange exactly 4 units of X. The countries partially specialize in their areas of comparative advantage

  1. How much labor must it move from producing Y to producing X to increase its production of X by 4 units?

 

 

∆L =

 

  1. In the country that specializes in producing Y, how much additional Y must it produce?

 

 

∆Y =

 

  1. In the country that specializes in producing Y, how labor must it move from producing X to producing Y?

 

 

∆L =
