Answer:
zero percent
Explanation:
Given data in the problem:
The growth rate of GDP in the United States = 4.2 percent
The growth of GDP due to the capital = 2.9 percent
The growth of GDP due to the labor = 1.3 percent
now, the contribution of the capital and labor in the growth of GDP = 2.9 percent + 1.3 percent = 4.2 percent
Now, the contribution from labor and the capital sums up the total growth rate of the GDP of the united States.
Hence, the growth rate from the technical progress is zero percent
