Both economic theory and modern economic history show that productivity growth in non-agricultural sectors has consistently outweighed that of the agricultural sector. Thus, as development progresses, employment, which had been centered around the agricultural sector, becomes more and more dependent on the industrial and services sectors. This relationship between economic growth, and the move ...

This paper provides a unified growth theory, i.e. a model that explains the very long-run economic and demographic development path of industrialized economies, stretching from the pre-industrial era to the present-day and beyond. Making strict use of Malthus’ (1798) so-called preventive check hypothesis – that fertility rates vary inversely with the price of food – the current study offers a n...
