Total Factor Productivity seems to be stagnant. This graph was made using the FRED data base hosted by the St. Louis Fed. I divided GDP by Kapital ^.3*Labor^.7. It was more work using the new Blogger and making the graph. The joys of productivity. I owe a huge thanks to Dr. Andrew Abel for his help. Dr. Abel showed me the correct data series to use for investment. I am always surprised by the generosity of others to help.
