A study of Swedish data shows that such changes have contributed approximately 0.2 percentage points a year during the second half of the 1990s(3). 3 The same picture, although applying to the situation in the United States, can be seen in US studies. 4 Another possibility to improve the accounting is to look more closely at the link between labour and capital. So far the analysis has been based on the two resources in production being dealt with separately. But there are good examples of when labour and capital are interdependent. Technical knowledge becomes particularly valuable with regard to the development of programs and systems, the production of computer games, etc. Artists, film stars, elite athletes/sportsmen and others active in the experience industry get more out of their special skills through the developments in IT and communications. The US central bank governor Ben Bernanke uses the company Walmart as another example. 5 For the purpose of using the IT investments the company had made, they reorganised their work, gave the staff further training and changed the relationship to their suppliers. This type of technique for general use, of which IT can be said to be an example, can in turn push up other investment, such as further education. There are also other ways of developing the analysis.
