No one's gonna look at this, and I don't know if this helps, but from a Production standpoint in EconA:
Skilled Labor produces y more effectively
Unskilled Labor produces x more effectively
EconA producing soly x or y is double the output of that of that in EconB. Graph all 3 lines on the same plane. These are the equations:
EconA, Skilled: Y= -2x + 400
EconA, Unskilled: Y=(-1/2)x + 200
EconB, Unskilled: Y= -x + 200
Solving the system for EconA,Skilled and EconA, Unskilled yields the equilibrium point at (x,y)=(133 1/3, 133,1/3) (which is sloppy to me because fractions are meaningless in this context).
Looking at the graph, you can see that from that point of intersection, the difference of production of BOTH products x and y between Economy A and B is at its highest (a deficit of 66 2/3 units).
I don't know if any of this information is useful.
But this is:
- In Economy A, Skilled Labor produces twice as much Product Y than Unskilled Labor in either economy.
- Skilled Labor *COULD* produce some Product X, but it stands to reason that Unskilled Labor in Economy A can do it cheaper at the same output, and Economy B can do it even cheaper than Economy A at the same output.
- Consumers in dirt-poor Economy B won't generally want to buy the same product at the same output at a higher price from Economy A. Most consumers in Economy A won't know or care if Product X comes from North Korea.
It stands to reason that Economy A *SHOULD*, in fact, produce only Product Y.
Unless I missed something
