When Labor input is 250 billion hours, GDP is 20,000 billion dollars. When Labor input is 252 billion hours, GDP is 20,120. What is the MPL (Marginal Product of Labor) when L = 250?
20,000 dollars per year
120 dollars per hour
60 thousand dollars per year
60 dollars per hour
30 dollars per hour
Marginal product of labor = increase in GDP / Increase in labor hours
= (20120 - 20000)billion / (252-250)billion
= 120/2
= 60
Thus, the answer is (c) 60 dollars per hour
