The three-compartmental demographic model by Korotaeyv-Malkov-Khaltourina, connecting population size, economic surplus, and education level, is considered from the point of view of dynamical systems theory. It is shown that there exist two integrals of motion, which enables the system to be reduced to one nonlinear ordinary differential equation. The study of its structure provides analytical ...

OBERT MALTHUS is exemplary in presenting a basic pessimism in his assessment of the prospects of the labouring poor— a pessimism about the long-term growth possibilities of an essentially organic, agrarian economy that he shares with his fellow classical economists writing in the second half of the eighteenth, and the early nineteenth, centuries. 2 He is, of course, well known for identifying w...

Based on China’s population data from 1953 to 2020, the Leslie model combines fertility rate of women childbearing age by region and age, sex ratio birth population, mortality rate, migration between urban rural areas curve fitting function, application ARIMA predict rates construct a discrete dynamics system in order future development trajectory. The improved Leslie, BP Malthus models were co...

In the many transitions from foraging to agropastoralism it is debated whether the primary drivers are innovations in technology or increases of population. The driver discussion traditionally separates Malthusian (technology driven) from Boserupian (population driven) theories. I present a numerical model of the transitions to agriculture and discuss this model in the light of the population v...

Models of population dynamics have been the subject of much study in biology. The essay of Malthus (1798) rst suggested exponential growth. The idea of quantitative limits on growth is usually attributed to Verhulst (1838), who pioneered the use of the logistic equation (LE), and to Lotka (1920) and Volterra (1926), who considered models of predators and prey. Typically these early studies of p...

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 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 new a...

The Malthusian doctrine put forward in the middle of the 18th century, forecast that the population of the world would, in a relatively short period of time, find it increasingly difficult to feed itself. I think it is obvious that, sooner or later, the world’s population must reach saturation point when the tragedy envisaged by Malthus will be with us. However, there are many ways of deferring...

Abstract The late 1960s witnessed a key conjunction between political activism and the history of science. Science, whether seen as touchstone rationality or oppression, was fundamental to all sides in era Vietnam War. This essay examines historian Robert Maxwell Young's turn Marxism radical politics during this period, especially his widely cited account ‘common context’ nineteenth-century bio...
