Criticism of Harrod-Domar growth model?
Various, sometimes conflicting definitions of these terms have appeared in the literature; some have based the distinction on the nature of the subject matter studied, while others have emphasized the difference in analytic approach.
Utilizing the first of these viewpoints, we may distinguish between a stationary economic phenomenon—that is, one that does not change with the passage of time— and a developing or changing phenomenon. But no matter which type of phenomenon we study, we may focus upon it an analytic apparatus which we describe as dynamic—that is, one that takes explicit account of the role of the passage of time in the structure of the subject—or we can subject it to a static analysis, which deals with its mechanism at a given moment and abstracts from the effect of past events on the Evsey domar essays in the theory of economic growth and future.
For further discussion of the definitions, see Samuelsonpp. In earlier periods of economic analysis, the distinction between statics and dynamics was not very clear-cut. Characteristically, the object of the economist was to provide useful advice to the rulers of the body politic rather than systematic studies defensible under the canons of scientific analysis.
Such a pragmatic concern justified the construction of a pastiche composed of both static and dynamic relationships that switched from one approach to the other whenever it became convenient.
For example, monetary theorists, in their discussions of the effects of an increase of the supply of currency, turned rather early to an examination of the sequence of events whereby the initial stimulation of production and prosperity resulting from an injection of funds may gradually be dissipated by translation into a rise in price levels that is ultimately diffused throughout the economy.
Cantillon and Hume were among those who described this process perspicaciously and in considerable detail. The marriage of the two analytic approaches attained its apex in the work of the early classical economists, including Malthus and Ricardo, and culminated in the work of J.
In these writings a purely static theory of wages, profits, and rent was wedded to a mechanism that accounted for the rates of growth of capital and population.
In rough outline the model may be described as follows: In the short run wages are determined by the demand for labor, which increases with the supply of capital. But if the demand for labor is high, causing high wages, population growth is encouraged; and this gradually increases the supply of labor and reduces wages.
Profits are thereby increased, stimulating investment both by enhancing its profitability and by augmenting the supply of funds that are normally used for this purpose.
Thus, the levels of capital supply, population, and labor supply will grow with the passage of time, and in this process wages will frequently be kept up by high demand for labor.
But, in the classical model, this process cannot continue indefinitely. The supply of natural resources, including land, being fixed, a growing population must result in an ever increasing ratio of labor supply to resources.
Here enters the principle of diminishing returns, which states that if the supply of natural resources remains constant, increased labor supply will, at least after some point, yield diminishing marginal returns; that is, further increments in the labor supply will add less to the national product than did previous increments.
Ultimately, then, the capital-population growth process will reduce per capita output and hence will decrease either wages or profits or both. Reduced profits will cause decreased investment, decreased demand for labor, and decreased wages. And when wages have been reduced to a minimal level representing either the amount necessary to provide subsistence or some habitual minimum living standard, population growth will cease.
From this model the classical economists derived a number of policy conclusions, among them their approbation of such measures as late marriage, which reduces the rate of growth of population, and their general denigration of activities designed to enforce increases in wage rates, which in their view could only temporarily ameliorate the lot of the laboring classes and would do so at a heavy cost—the increased imminence of the unhappy stationary state.
By bringing the static relationship between wages and the demand for labor together with the dynamics of population growth and marginal productivity, the classicists were able to derive conclusions which, right or wrong, were at least relevant for public decisions.
For further information on the classical and other earlier dynamic models, see Adelmanchapters ; Baumol chapters 2, 3. Toward the end of the nineteenth century, when economic analysis began more self-consciously to follow the precepts of scientific method, statics and dynamics were more rigidly compartmentalized.
At first this meant in practice that systematic dynamic analysis was largely abandoned and was confined primarily to some casual observations about the time processes that underlay the well-developed static constructs.
Both of the latter economists were fully cognizant of the difficulties besetting the equilibrium assumptions of static price theory, recognizing that in a world of imperfect knowledge initial pricing and supply bids were unlikely to approximate their equilibrium levels.
They therefore described, in rather vague terms, intertemporal processes whereby the market, by trial and error, might gradually approach the price and output levels predicted by static theory. Only in the last few decades has dynamic analysis developed into the independent and complex body of theoretical matter to be described presently.
However, before that development occurred, a related analytic approach, comparative statics, provided a substantial contribution to economics.
Comparative statics is a method of theoretical investigation of the consequences of a change in some datum in an economic model. For example, to determine the effects of a tax rate change on the level of output of a firm, a comparative statics study examines the two relevant equilibrium outputs—the equilibrium output under the old tax rate and the modified equilibrium output that would result from the imposition of the alternative tax arrangement.
In effect, the comparative statics approach starts from an equilibrium position, then imposes an experimental variation on one or more of the parameters of the model and examines what has happened after the smoke has cleared away and the system has had time to settle down to a new equilibrium.The papers of Evsey Domar span the years through , with the bulk of the papers being dated between and Published Essays in the Theory of Economic Growth: Professor of Economics, Massachusetts Institute of Technology: Guide to the Evsey D.
