"the search for new knowledge which creates imperfect competition"

 Outro trecho sobre a concorrência imperfeita:

"In both Adam Smith and in neo - classical theory there is in some fundamental way a contradiction between the notion of perfect markets and the way the economy adds knowledge. This problem spills over to how economic theory today explains profits. There is no incentive to produce new knowledge in perfect markets – the possibility of appropriating the fruits of new knowledge is absent. By letting new knowledge enter the system like ‘‘manna from heaven’’, the very engine of growth – the search for new knowledge which creates imperfect competition – is excluded from mainstream theory. For this reason, an understanding of how different degrees of imperfect competition is caused by conditions of production is at the very core of any understanding of economic growth. Economic theory, however, does not have a relevant theory of production, and of the role of human knowledge in this process."
