Malthus Revisited: Fertility Decision Making based on Quasi-Linear Preferences

Malthus’ (1798) population hypothesis is inconsistent with the demographic transition and the concurrent massive expansion of incomes observed among industrialised countries. This study shows that eliminating the income-effect on the demand for children from the Malthusian model makes it harmonise well with industrial development.demographic transition; fertility; Malthus

Malthus Was Right After All: Poor Relief and Birth Rates in Southeastern England

The payment of child allowances to laborers with large families was widespread in early nineteenth-century England. This paper tests Thomas Malthus\u27s hypothesis that child allowances caused the birth rate to increase. A cross-sectional regression model is estimated to explain variations in birth rates across parishes in 1826-30. Birth rates are found to be related to child allowances, income, and the availability of housing, as Malthus contended. The paper concludes by examining the role played by the adoption of child allowances after 1795 in the fertility increase of the early nineteenth century

Malthus and Ricardo on Economic Methodology

The paper is a comparative study of the methodologies of Malthus and Ricardo. Its claims are: (i) economic laws almost always admit of exceptions for Malthus; for Ricardo even contingent predictions allow no exception apart from random temporary variations; (ii) both rely on the prestigious Newtonian paradigm, while interpreting it according to two distinct methodological traditions (the one deriving from MacLaurin, the other from Priestley); (iii) the choice of stressing what happens during intervals or in permanent states leads to opposing definitions of the main problem of economic science in so far as equilibrium is always already given for Ricardo and is never given for Malthus; (iv) their use of the ambiguous notion of "tendency" leaves unclear for both the degree of predictive power with which theories are endowed; (v) what both share is the idea of a natural order and this idea is the source of both shortcomings and endless disagreement

7. Malthus and the Problem of Population

One of the central beliefs of classical economic theory was that there is an inexorable tendency for population to press against the available natural resources, especially those providing the food supply. This doctrine, though not originating with him, was eloquently expressed by Thomas Robert Malthas (1766-1834) in an essay which first appeared in 1798. Malthus, a high-ranking graduate of Cambridge University, was a clergyman in the Church of England before he became a professor of history and political economy at the East India College, Haileybury, in 1805. This college had just been established by the British East India Company to train men for its service in Asia. Malthus, one of the first persons ever to hold a professorship in economics, continued in this post for the remainder of his life. [excerpt

Malthus revisited

Although mineral resources are non-renewable and unevenly distributed, global supply has so far kept up with demand. However, mankind is now moving into an era of unprecedented population growth and environmental change. As demand continues to rise and the need to mitigate and adapt to environmental change becomes more pressing can the abundant mineral supply we have enjoyed be sustained

Collective and individual rationality: Robert Malthus’s heterodox theodicy

This paper forms part of a research project investigating conceptions of the relationship between micro-level self-seeking agent behaviour and the desirability or otherwise of the resulting macro-level social outcomes in the history of economics. I identify two kinds of conservative rhetorical strategy, characterised by reductionism, and by holism plus an invisible hand mechanism, respectively. The present paper extends this study to Malthus, focusing on the various editions of his Essay on Population and his Summary View of the Principle of Population. Like the reductionist (Friedman, Lucas) and holistic (Smith, Hayek) proponents of laissez-faire, Malthus, too, is a defender of ‘the present order of things’ and an advocate of dependence on spontaneous forces. Malthus starts out within the eighteenth-century providentialist paradigm epitomised by Adam Smith and Dugald Stewart, but he later abandoned providentialism, adopting a more reductionist standpoint. Like Smith and Stewart, he takes a conservative political stance and opposes radical reform of society. But in taking up the arguments of the leading reformers of the day, Godwin and Condorcet, he is drawn by the logic of his argument to a position very far removed from Smith’s stoic optimism. The weapon he deploys against the reformers is the principle of population, by means of which he is able to portray the present state of society as something natural, eternal and inevitable, something in common with the animal and vegetable kingdoms. Though a potent weapon against the utopians, at the same time the principle of population undermines providentialism In the First Essay he tries to mitigate this by presenting a theodicy to reconcile his theory with a version of providentialism, but within weeks of publication he begins work on its replacement, a secular and reductionist argument that individual self-interest can guide us to socially desirable outcomes

Thomas Robert Malthus: The Economist

As Robert Heilbroner has so aptly observed, economics has produced a handful of men whose contributions to mankind have been more decisive for history than many acts of statesman who basked in brighter glory, often more profoundly disturbing then the shuttling of armies back and forth across frontiers, and more powerful for good and bad than the edicts of kings and legislatures. One such person cited by Heilbroner is Thomas Robert Malthus

Malthus v. Bailey on the Measure of Value: A Lesson in "Methodological Humility"

That Malthus was guilty of egregious error in his claim to have established the labor-commanded magnitude as an "invariable" unit of value is well-known. Even his modern biographer could appeal only to a "kink or a crotchet, some kind of cerebral block" to excuse Malthus's persistent failure to recognize the manifestly tautological character of his position. Yet the familiar form of Malthus's argument, as it appeared in his later work, differed in several respects from its earliest statement in the first edition of his Principles. In this essay we trace out the several changes made to Malthus's argument, often in response to his many critics; and we find in the midst of those alterations a common characteristic that serves to reveal the character of that "kink or crotchet": an obsession with mathematical operations producing a unit outcome. We draw two lessons from this sorry episode in our history. First, the sterility of the debate between Malthus and his critics serves to highlight the central importance of a precise and commonly understood vocabulary of scientific expression. This was, it is true, no more than a dispute over words; but as they are the vessels of our thoughts, words-of precise and commonly understood meaning-are critical to the progress of a science. Second, the heat of that debate highlights the insidious capacity of practitioners to mistake for scientific principles what are no more than "intricate series of definitions," a lesson which, when taken seriously, cannot fail but to impart a salutary "methodological humility."Labor-command; Malthus; Ricardo; Samuel Bailey

Path Integrals and Perturbation Theory for Stochastic Processes

We review and extend the formalism introduced by Peliti, that maps a Markov process to a path-integral representation. After developing the mapping, we apply it to some illustrative examples: the simple decay process, the birth-and-death process, and the Malthus-Verhulst process. In the first two cases we show how to obtain the exact probability generating function using the path integral. We show how to implement a diagrammatic perturbation theory for processes that do not admit an exact solution. Analysis of a set of coupled Malthus-Verhulst processes on a lattice leads, in the continuum limit, to a field theory for directed percolation and allied models.Comment: 33 pages, 6 figure
