ABSTRACT
It is a very widespread opinion among economists nowadays that the theoretical structure of economics, as it has developed over the last generations, bears – to a too large degree – the mark of static ideas. On this issue it seems that everybody is in agreement. Everybody agrees on the need of introducing something more dynamic. But when we come to the question of knowing what this dynamic thing is, there is no longer any unanimity. It is really an issue that has been discussed very much.
