| Outline of Final Research Achievements |
We find a remarkable improvement in model performance once we introduce R&D capital into the investment-based asset pricing model which explains the firm value or Tobin’s q. In addition, the increase in firm value with the introduction of additional unit of capital is far larger for R&D capital compared with that of physical capital, particularly for innovative firms belonging to the drugs and electric and electronic equipment industries. Tobin’s q is regarded as the unique explanatory variable for physical capital investment in the finance and economic literature, however, we show that Tobin’s q is an inappropriate measure of physical capital investment for those innovative firms.
