| Outline of Final Research Achievements |
This project investigates the inter-industry spillover effect of both R&D stock and IT capital in Japanese manufacturing industries. A translog cost function model was constructed for ten Japanese manufacturing industries. Most of the tested parameters for industry R&D stock and R&D spillover were significant, demonstrating their contribution. R&D spillover reduced costs in all industries in most periods. The impact of R&D spillover on costs was strong in industries where the industry R&D stock is large. Increases in R&D spillover led to increased markup and reduced welfare, a characterization of excess R&D spillover. Parameters for industry IT externalities was significant in all cases, demonstrating their contribution. The all results of values of elasticity show the negative sign that are consistent to the theory. IT externalities reduced costs in all industries in all of observation periods. The elasticity of all industry getting large and the peak is 1988 and 1989.
