Explanation of Solution

Percentage change in labor productivity can be calculated by dividing the change in productivity by the old output.

For country A, it is

  % change in productivity = 48-4040×100= 20%

Similarly, it can be calculated for other countries:

    Output per HourPercentage Change In productivity
    20042014
    Country A404820
    Country B253540
    Country C2350
    Country D0.50.620

Country D had lowest productivity in year 2004, which was 0.5 units/hr. But the percentage growth of labor productivity is highest in country C, which is 50%. Hence, it is not true that productivity growth was highest where the initial level of productivity was the lowest.

Suppose that real GDP per capita of the United States is $32,000 and its growth rate is 2% per year and that real GDP per capita of China is $4,000, and its annual growth rate is 7%. How long will it take real GDP per capita of the United States to double?
In 2000 GDP per capita was 18.3, capital/output was 3.3, human capital was 4.8. In 2010 GDP per capita was 23.3, capital/output 5.7, human capital was 4.5. In both years the production function is Cobb-Douglas with a value for α of 0.4. What was the ratio of GDP per capita in 2010 to 2000 due *just* to the change in the capital/output ratio? Use 2 decimal places.
