This is probably evidence of how significant these changes are and that they are rapidly occurring worldwide. Intangible assets literally are difficult to measure.
However, taking just one example -- namely, the importance of these assets being discussed both within academia and the business sector -- reveals that it is becoming hard to assess firms' investment activities and the effects of monetary policy without considering the impact of these assets. Therefore, I believe that it is necessary to adequately address these changes in the economic structure.
