Economic growth In the long run

We present new data on real output per worker, schooling per worker, human capital per worker, real physical capital per worker for 168 countries. The output data represent all available data from Maddison. The physical capital data represent all available data from Mitchell. One major contribution is a new set of human capital per worker, the foundation of which comes mostly from Mitchell. We provide original estimates of schooling per worker & per young worker. With our preferred measure of human capital, between 66 percent to 90 percent of all the variation in long run growth can be explained by variation in the growth of inputs per worker, and only 10-34 percent from variation in TFP growth! Furthermore between 66 percent and 80 percent of the variation in log levels can be explained by variation in the log input levels and only 20 percent to 34 percent is explained by variation in log TFP levels
