Malthusianism is a theory that population growth is potentially exponential, according to the Malthusian growth model, while the growth of the food supply or other resources is linear, which eventually reduces living standards to the point of triggering a population decline.
P 0 = P(0) is the initial population size, r = the population growth rate, which Ronald Fisher called the Malthusian parameter of population growth in The Genetical Theory of Natural Selection, [2] and Alfred J. Lotka called the intrinsic rate of increase, [3] [4] t = time. The model can also be written in the form of a differential equation:
According to Kaldor, “The purpose of a theory of economic growth is to show the nature of non-economic variables which ultimately determine the rate at which the general level of production of the economy is growing, and thereby contribute to an understanding of the question of why some societies grow so much faster than others.” [2] [1]
There are appreciable variations (2 to 5 percent) in the rate of growth of labor productivity and of total output among countries. Kaldor did not claim that any of these quantities would be constant at all times; on the contrary, growth rates and income shares fluctuate strongly over the business cycle. Instead, his claim was that these ...
A population cycle in zoology is a phenomenon where populations rise and fall over a predictable period of time. There are some species where population numbers have reasonably predictable patterns of change although the full reasons for population cycles is one of the major unsolved ecological problems.
The OLG model is the natural framework for the study of: (a) the life-cycle behavior (investment in human capital, work and saving for retirement), (b) the implications of the allocation of resources across the generations, such as Social Security, on the income per capita in the long-run, [1] (c) the determinants of economic growth in the ...
Hans Singer asserted that the balanced growth theory is more applicable to cure an economy facing a cyclical downswing. [7] Cyclical downswing is a feature of an advanced stage of sustained growth rather than of the vicious cycle of poverty. Hirschman also stated that during conditions of slack activity in developed countries, the stock of ...
Demographic economics or population economics is the application of economic analysis to demography, the study of human populations, including size, growth, density, distribution, and vital statistics.
