This study uses behavioral theory to examine how performance and slack affect R&D expenditures and innovation rates in 11 large Japanese shipbuilding firms from 1971 to 1996. The results show that: 1) R&D intensity increases when performance decreases relative to aspirations or when organizational slack increases. 2) The rate of launching innovations decreases when performance increases relative to aspirations, and this decrease is more rapid for higher performance above aspirations. 3) The study emphasizes including decision-making variables related to risk-taking when examining innovation, rather than only focusing on knowledge management.
