Solow Model

In country X labors relative share of national income is 60%. Which of the following will a 1% increase result in the largest increase in country X’s GDP? A) Labor. B) Technology. C) Capital. I chose A, but the answer for this question is B. This is strange because it seems the explanation in the book FOR A DIFFERENT PROBLEM leads me to a different conclusion. (my appologies, I didn’t make that clear before) "Country ABC’s % share of national income relative to labor is 70, while the share of capital is 30. For country ABC, a 1% increase in the labor force will lead to a much greater increase in economic output than a 1% increase in the capital stock."

It seems like the explanation for the example is contradictory to the explanation for the problem. Can someone clarify? Thanks! smiley

The explanation is incomplete. Also, it says labor is 70%; you’d said 60%. Nevertheless, if labor’s share is, say, 60%, then:

  • A 1% increase in technology (factor productivity) will increase GDP 1%
  • A 1% increase in labor will increase GDP 0.6%
  • A 1% increase in capital will increase GDP 0.4%

Hi. I should have made it clear before that the explanation I quoted was from a different problem (an example, not an actual review problem) That is why I am confused. Sorry about the misunderstanding.

yea, the information was definitely not clear enough.
