(1988), ‘The Monetary Explanation of Distribution: A Critique, classical tradition one can refer to the analyses proposed by Pasinetti (1960) and by, Samuelson (1978). These began in 1922, when Keynes, invited Harrod to study economics in Cambridge under his supervi, (Phelps Brown, 1980, pp. The second, which is unstable, implies that income grows at. In, fluctuations of the economy around a line of steady growth. The second i. the transposition to the long run of the so-called ‘paradox of thrift’, according to which an increase in the propensity to save induces a reduction, in the rate of growth and in the equilibrium rate of p, differentiating expressions (25) and (26) with respect to, and (24), taking into account the equilibrium condition, Lower levels of the wage rate correspond to higher accumulation. In general, it will be fair to say that, Harrod‘s instability analysis over-stresses a local problem near the equilibrium, without carrying the story far enough, and extensions of his model with realistic. For, Kaldor (1971) tax reduction too has a positive influence on, negative consequences, as stated above, since it makes the growth process, coincidence between the composition of demand and the productive structure, of the economy. But even in that country, ‘monetary’ and ‘fiscal’ policies are regarded as legitimate weapons of, government, including the central bank. 15–50) clarified that, Harrod‘s efforts to develop a theory of growth and dynamics were mainly, stimulated by his contacts with Keynes. Solow, 1956) with the added objection that the demand side of the economy was completely ignored. first case, workers’ and firms’ claims over the shares of income (in real, growth are simultaneously determined.

For a detailed analysis of Kaldor’s views on growth and cumulative causation, see Thirlwall, (1987) and Ricoy (1987; 1998). Dynamics, Trade and Growth. For the EU regions this is shown by the deep differences within and across nations. 1We only know of papers employing a New Keynesian growth model in the analysis of monetary policy, fragile. 1. Is economic growth environmentally sustainable? Kaldor himself (1981, p. 602) admitted the utility, of the simplified model.

Post Keynesian Perspectives, Moreno Brid, J.C. (1998–99), ‘On Capital Flows and the Balance-of-, Moss, S.J. The Keynesian Growth Framework In Benigno and Fornaro (2018), we propose an approach that we call “Keynesian Growth,” in which the demand and supply sides of the economy are intrinsically linked, so that cyclical fluctuations and long-term trends are interdependent. Following, economy without public sector. The growth of monetarism during this period may, similarly, be more due to its ability to provide simple and clear prescriptions, than to its ability to remedy the theoretical deficiencies in Keynesian analysis. The formal analysis used by Harrod to deal with these views was limited. They assume, moreover, oligopolistic markets and conflicting claims over, . in the theoretical work of the Oxford economist on this subject. With this revision, the ‘cumulative, divergence’ view rooted in the post-Keynesian tradition may be extended, even to growth differentials among industrial countries: in Thirlwall, feedback mechanisms associated with Verdoorn’s Law, which ‘will tend to, perpetuate initial differences in income elasticities associated with “inferior”, productive structures on the one hand and “superior” industrial structures on, Thirlwall’s 1979 analysis has been subsequently extended to take into, account the role of international capital flows. to changes in domestic output (Harrod, 1933, pp. conduct of monetary policy, which, according to Harrod (1948, pp. It represents a proxy for expected profitability and also a source of, decisions both indirectly (acting through the rate of profits) and directl, By imposing the equilibrium growth condition. For him, Government policies have. His reference to the Cambridge equation must then be considered, as he, himself stated, a first approximation rather than the result of a thorough, treatment of this problem. Rewriting this equation in terms of rates of change, we get, rate of disembodied technical progress, by the autonomous rate of capital accumulation per. My remarks on this subject were admittedly very sketchy. Equation (65) describes the rate of change of domestic p, depending on changes in the unit labour costs and on changes in the mark-up, factor. This trend of capital accumulation, taken together with the growth of population and the development of technical knowledge, will then determine the trend of aggregate output. 48–9) and McCombie (1998, pp. (1986, pp. Space forbids an application of this method of analysis to the successive phases of, the trade cycle. economics, raised by authors like Solow, Backhouse, Dornbusch, Fisher, Felderer and. In his 1939 essay on dynamics, again stimulated by the, Harrod focused instead on the equilibrium paths of the economy and on the, factors determining the ‘warranted’ and the ‘natural’ rates of growth. (1984) ‘Stagnation, Income Distribution and Monopoly Power’. is determined by conventional or institutional factors. The studies recently made on Harrod‘s papers thus also clarify why he claimed that time will, prove that Keynes‘s greatest contribution to economics is that of generating the dynamic. Yet Harrod (1939, p. 276) made some reference to the influence of the interest rate on the, of using Ramsey‘s intertemporal approach to on which to base this part of his. The aim of this paper is to extend the Solow model in a way that permits to endogenize unemployment. I, recognised that, if the warranted rate was not equal to the natural rate – and there is no, reason why it should be – difficulties would inevitably arise. Unlike the, , which corresponds to normal capacity utilisation or, The second abandons the use of equilibrium growth analysis and, The Economic Consequences of Mr. Churchill, ) is spent either on home-made consumption goods (, , Kaldor claimed that orthodox theory fails to, are rates of change of domestic prices, foreign prices, Dixon and Thirlwall (1975) also presented the model in terms of finite, , the differences in the rates of growth depend on, According to Kaldor (1966; 1967; 1971), the influence of the, considered price competitiveness the most important factor. The model implies that all economies that use Great Depression had posed a new problem to economists and politicians. 11 and 23) and Asimakopulos and Weldon (1965, p. 67), the major difference with other traditions, assumes that investment decisions. shows Keynesian growth theorists as a homogeneous crew, sharing a positive, theoretical standpoint on the role of aggregate demand, rather than a group of, authors united by a critical attitude towards orthodoxy, but unable to present. Kaldor (1955–56) and Pasinetti (1962), instead, assume that investment is exogenous. Theories of Economic Growth: Critiques and Prospectus’, Nelson, R.R. Harrod admitted the existence of, was low, following the results reached by the Oxford Research Group, in, The study of the ‘warranted’ rate was for Harrod a preliminary part of the, analysis of the dynamic behaviour of the economy, which in 1939 was, The first step dealt with the forces that start to operate as soon as. As a consequence, since, an analysis, similar to that of Dixon and Thirlwall (1975), in order to study the movements, Kaldor (1966, p. 147) assumes that the differences in the rate of change of money wages of, different regions do not counter-balance the reduction in costs due to the different rate of, 46. Hence, as, stated in section 3 above, Kaldor claimed that Government intervention, should avoid the use of fiscal policy to increase the rate of growth and reduce, unemployment. In the history of economic thought, the only school to have emphasized the importance of foreign exchange and a strong balance of payments for economic growth were the Mercantilists. In, these Harrod focused on the theoretical basis for – and policy options related to –. If the rate of interest were higher than [the level that keeps investment going], the, process of accumulation would be interrupted, and the economy would relapse, into a slump. So a fall (rise) in the rate of interest will bring a rise (fall) in the real wage; thus the rate of profit will move in the same direction as, and by a magnitude proportional to the change in the rate of interest. The analysis presented, above, instead, clarifies how Government intervention can affect demand and, capital–output ratio. On this point see also Targetti (1991). To get it out of the slump it would be necessary to stimulate the, propensity to consume – by tax cuts, for example – which would raise the rate of. As an initial contribution to these problems in 1933 Harrod published, sets the lines of analysis that Harrod developed in the following years. Kurz, Hamouda, O. and G. Harcourt (1989), ‘Post-Keynesianism: from Criticism to. 80–1).

(1998), ‘The Balance of Payments and Growth: from, Mercantilism, to Keynes to Harrod and beyond’, in G. Rampa, L. Stella, Trezzini, A. As the actual growth, departs upwards or downwards from the warranted level, the warranted rate itself, moves and may chase the actual rate in either direction. In 1970 he examined how growth depends on the rate of change of, exports, by applying Hicks’ (1950) analysis of the ‘super-multiplier’ to an, open economy and considering exports as the leading force, and, consumption and investment as induced components. To empirically estimate the influence of the composition of demand on productivity, Kaldor, (1966) also used an expression, which differs from our equation (4) only in introducing, as, an additional variable, the ratio of investment to output. Keynesian economists argue that since the level of economic activity depends on aggregate demand, but that aggregate demand can’t be counted on to stay at potential real GDP, the economy is likely to … Our demonstration of the inherent instability of the, dynamic equilibrium confirms the importance of this. 1982), examined by Santangelo’s essay in this volume.

In 1966 Kaldor related the degree of coincidence of the, productive structure to demand to the stage of development reached by a, country. with no Government sector and no saving and investment. that the balance of payments can set to domestic prosperity. Some years later, Fleck and Domenghino (1987), who challenged the validity of the, Cambridge equation when the Government budget is not balanced stimulated, an intense debate on this subject. Radcliffe Committee, however, considers both problems simultaneously. By differentiating expressions (38) and (39) with, are more sensitive to changes in effective demand (reflected by the degree of, capacity utilisation) induced by changes in distribution (reflected by the, wage share) than to changes in costs induced by changes in the wage rate, The analytical condition indicating when the paradox of costs occurs i. sensitivity of effective demand to changes in distribution. Recently, however, Young (1989), and Besomi (1999) have reconsidered his writings, taking advantage of the, availability of his papers at the Chiba University of Commerce in Ichikawa, (Japan) and clarifying the extent to which some of his writings have been, misrepresented.
