Neo Malthusian vs Malthusian
Malthusian and Neo-Malthusian Theories/ Ran Abramitzky and Fabio Braggion
Malthus’ Legacy
Few economists have had such controversial ideas, and generated a debate on such a scale as Thomas Malthus. In “An Essay on the Principle of Population”, published in
1798, the English economist made public his theory on population dynamics and its relationship with the availability of resources. The essay was the result of his skepticism towards positivist theorists, praising the perfectibility of man and greeting the advances and diffusion of human knowledge as a source of welfare and freedom for future generations. Disagreeing with such perspectives, Malthus maintained that the development of mankind was severely limited by the pressure that population growth exerted on the availability of food.
The foundation of Malthus ' theory relies on two assumptions that he views as fixed, namely that food and passion between sexes are both essential for human 's existence.
Malthus believed that the world 's population tends to increase at a faster rate than its food supply. Whereas population grows at a geometric rate, the production capacity only grows arithmetically. Therefore, in the absence of consistent checks on population growth, Malthus made the gloomy prediction that in a short period of time, scarce resources will have to be shared among an increasing number of individuals.
However, such checks that ease the pressure of population explosion do exist, and
Malthus distinguishes between two categories, the preventive check and the positive one. The preventive check consists of voluntary limitations of population growth.
Individuals, before getting married and building a family, make rational decisions based on the income they expect to earn and the quality of life they anticipate to maintain in the future for themselves and their families. The positive check to population is a direct consequence of the lack of a preventive check. When society does not
