Thomas Malthus was an economist who put forth the principle that population grows based on an exponential growth model, while food and resources grow based on a linear growth model. Based on this, Malthus predicted that eventually demand for food and resources would out outgrow supply, with doom-and-gloom consequences.

Chapter 2 Population Ecology and Human Demography
Malthus published a book (An Essay on the Principle of Population) in 1798 stating that populations with unlimited natural resources grow very rapidly but once population size exceeds available resources, population growth decreases dramatically. ... The mathematical function or logistic growth model is represented by the following equation:

Roots of demographic considerations started with Malthus in 1826 period of time when human population began to show exponential growth. He noted human populations were increasing exponentially but food supply only increased in a linear fashion. Predicted human population would eventually be …

Writing in the late 18th century, Thomas Malthus argued that the world was doomed to a standard of living where people were barely able to survive. His reasoning was that population tended to grow at a much faster rate than the resources needed to sustain that population, especially food. ... This equation is good because it identifies three ...

Malthus’s views remain influential today. Supporters of Malthus’s model suggest that characteristics of recent population growth pose even greater risks than when Malthus developed his thesis more than 200 years ago. However, criticism has been directed at both the population and resource depletion elements of Malthus’s equation.

The Malthus-Sismondi arguments, then, seem to fail to hold. However, things might change if we add a dynamic twist to this simplistic model. Ricardo erroneously transformed all of Malthus's and Sismondi's arguments, as we just have, into long-run comparative statics when they were, in fact, arguing in short-run dynamic terms.

Linear models for population growth probably were considered first by Thomas Malthus (1798), in his Essay on the principles of human population growth. Malthus (1766-1834) , Malthus utilized the continuous exponential growth equation: dN(t)/dt=rN(t) to study the demographics of human populations. Here . N

Equation (2) implies that dF/dN = L/N > 0, and d2F/dN2 = − L/N2 < 0. That is to say, marginal product is always positive (‘no limits whatsoever are placed to the productions of the earth’, Malthus 1798, p. 26); but it declines continuously as N increases, which is the law of diminishing returns.

Who was Malthus? About when did he live and what did he predict would happen to global human population? Define birth rate, death rate, emigration rate, and immigration rate. Write an equation to mathematically describe the relationship between these rates and the rate of population change. Describe hunter-gatherers and describe their populations.
