Intermediate layers in the knowledge-economy system

Description :
The knowledge-economy system is so complicated that its description and analysis with the help of he calculus of correlations between inputs and outputs can only yield approximate results. These can be useful when arguing for an increase in research and development outlays, but tend to be disputed when passing from correlations to a cause-and-effect analysis, as critics demand elucidation of relationships between inputs and the outputs. The present A. is of the opinion that the most practical way of solving this problem is to identify the structure of the model mapping the knowledge-economy system. If data necessary for a deterministic approach to modelling are missing, a probabilistic approach employing Markov chains is found to be useful. In the final part, the A. suggests the use of neural networks, which make possible to expand correlation links and hence to enlarge the basis of explanatory reasoning. - (BJ)
