Explanation:

According to Schumpeter , “Business cycles are almost exclusively the result of innovations in the industrial and commercial organization. Innovations are such changes of the combination of the factors of production as cannot be effected by infinitesimal steps or variations on the margin. [Innovation] consists primarily in changes in methods of production and transportation, or changes in industrial organization, or in the production of a new article, or opening of a new market or of new sources of material.”
