The purpose of this paper is to investigate what decreases TFP, why TFP has decreased in some countries and how large the decreases of TFP are. We focus on the quality of labor and capital inputs and use cross country data for the manufacturing industries of some OECD countries. We provide a comprehensive empirical investigation based on two hypotheses, substitutability and complementarity of labor input age and skill categories. Further, we provide an aging index, which tells how much the share of ICT capital should be increased to counterbalance decreases of TFP caused by the aging of the labor input.
