However, in the most widely accepted perspective concerning growth theory, if long-run development was seen as a consequence of innovation and the progress in knowledge, it was nevertheless implied that economists had not much to say about such phenomena and should hence take long-run technical progress as exogenous. The recognition that innovation and technical progress did not fall from heaven and the fact that a theory of long-run growth should explain technical change endogenously as well as, maybe, the conﬁdence placed by economists in the explanatory power of the model of economic behaviour led to a questioning of the very cautious attitude held by traditional neoclassical modelling. Innovation and technical progress can be seen as the result of purposeful activities such as investment, either in physical or human capital, R&D expenditures and so on.
