Suppose physical capital per worker increased to $60,000 between 1990 and 2000 and output per worker increased by $45,000 over the same time period. what percentage of productivity growth can be attributed to growth in total factor productivity? round your answer to two places after the decimal

The initial capital per worker is $30,000. The capital per worker rises to $60,000. The change in capital per worker is $30,000 (60,000 - 30,000). The change in output per worker is $45,000. The productivity growth attributed to growth in total factor productivity is as follows:Growth Rate = (Change in Input) / (Change in Output) x 100=30,000/45,000 x 100=66.67%Answer is 66.67%
