Robert Torrens: An Introduction

Posted by Alex M Thomas on 30th September 2013

Robert Torrens’s An Essay on the Production of Wealth (1821) is an important contribution to economic theory, in particular, to classical economic theory. Torrens was involved in the founding of the London Political Economy Club along with James Mill, David Ricardo, Thomas Tooke and others. Torrens has written extensively on monetary issues, on colonisation and on price theory. He is also credited with having discovered the comparative costs principle independently of Ricardo. This blog post focuses on his contributions to the theory of value and the possibility of a general glut in his debate with Ricardo.

Torrens is one of the very few (to be precise, nine) economists mentioned by Piero Sraffa in his Production of Commodities by Means of Commodities; Sraffa approvingly cites him for his method of treating fixed capital. Fixed capital is conceptualised as a distinct commodity (a joint product) alongside new commodities which emerge from the production process. Torrens utilises a theory of value based on ‘capital’ as opposed to Ricardo’s labour theory of value. But, how is ‘capital’ to be measured without the knowledge of values/prices? Ricardo recognises that when labour-capital ratios are not uniform across sectors, value will not be proportional to the embodied labour. And, as Carlo Benetti writes in his entry on Torrens in The Elgar Companion to Classical Economics, when the rate of profit is zero, the labour theory of value holds; however, the existence of positive profits does not per se invalidate Ricardo’s labour theory of value. A satisfactory resolution of this problem in value theory is to be found in Sraffa’s simultaneous determination of profits and prices.

The macroeconomics of Torrens, built on his theory of value and distribution, suggests the possibility of a general glut in the economy. On general gluts, Torrens writes: ‘a glut of a particular commodity may occasion a general stagnation, and lead to a suspension of production, not merely of the commodity which first exists in excess, but of all other commodities brought to the market’ (Torrens 1821: 414; as quoted in the Benetti entry on page 473). The underlying reason for this is a disproportion between the different sectors of the economy. Owing to the structural interdependence prevalent in an economy, a disproportion can lead to a fall in ‘effectual demand’. This will lead to a glut in commodities in that particular sector and in other sectors as a consequence of a fall in sales and incomes in that sector. This, evidently, is in direct contrast with Say’s law, loosely understood as – supply creates its own demand.

Other notable commentators on Torrens include Giancarlo DeVivo and Lionel Robbins. The latter published his work in 1958 entitled Robert Torrens and the Evolution of Classical Economics. In 2000, DeVivo edited and put together the Collected Works of Robert Torrens. Studying Torrens will certainly prove invaluable in gaining a deeper understanding of classical economics, and especially his views on general gluts might have contemporary use in relation to the economics of Keynes and Kalecki.

Thomas Tooke: An Introduction

Posted by Alex M Thomas on 15th June 2013

Thomas Tooke (1774-1858) made important contributions to monetary history, theory and policy. His monetary economics has been viewed in a favourable light by economists such as Ricardo and Marx. Moreover, Tooke’s conception of the rate of interest as a variable determined independently (of the profit rate) bears significant similarities with Keynes’s idea of the rate of interest as a ‘monetary phenomenon’. This post presents Tooke’s monetary theory in brief through his role in the debates between the Currency School (to which Ricardo belonged) and the Banking School (Tooke being the prominent member) in the early 1840s. The reference for this post is mainly the recent research carried out by Matthew Smith.

During Tooke’s time, the dominant view was that the rate of interest is governed by the rate of profit (on capital employed in production) implying that the former is determined by ‘real’ forces. In Smith, it is the competition of capital and for Ricardo, it is the wage rate and production conditions taken together. Tooke argued that the rate of interest is determined by institutional factors in the financial market and is independent of the rate of profit. In his later writings, he stated that it is the rate of interest which regulates the rate of profit with the former entering as a component in the costs of production of commodities.

The Currency School maintained that prices can be controlled by adjusting the quantity of money, as espoused by the quantity theory of money. That is, by altering the bank notes in circulation, it was believed that fluctuations in nominal income could be suppressed. This assumes that there are no time lags and that the velocity of circulation is constant. Tooke contested this policy and stressed the role for a discretionary monetary policy flexible enough to deal with different economic situations. The central principles of the Banking School are as follows: (i) the quantity of money in circulation is endogenously determined by the level of nominal income; (ii) ‘the rate of interest has no systematic influence on the inducement to spend’; and (iii) the rate of interest, being a component of commodity prices, exerts a ‘positive causal influence on the price level’ (Smith 1996: xliv-xlv). Such principles imply that the velocity of circulation is, in fact, a summary measure of the institutional setting of the financial market which can change when activity levels and prices vary.

Tooke’s contributions place a greater responsibility on the central banks. The principles of the Banking School imply that the interest policy of the monetary authorities can have lasting impact on real variables (such as income and employment) by influencing prices and the rate of profit. There is no long-run neutrality of money – monetary variables impact real variables. Moreover, attempts to control the quantity of money solely based on the rate of interest need not be successful since it is endogenously determined. Finally, the causation runs from prices to the quantity of money and not vice versa.

Wages in Economic Theory and Reality: Some Issues

Posted by Alex M Thomas on 2nd January 2013

Wages is the payment made to a labourer for the number of hours worked – sowing seeds, rolling tobacco, developing computer software or providing medical care in a hospital. How are these wages determined? Are they determined in a similar manner as that of commodities? That is, are they determined based on some sort of demand and supply mechanism? Or, are they predominantly set by non-economic forces which are not easily quantifiable? This blog post looks at the dominant neoclassical or marginalist viewpoint and contrasts it with the theoretical approach of classical economics. In this light, the post examines certain characteristics of the Indian economy relating to labour and employment.

The basic principles of neoclassical economics tell us that the price and quantity demanded and supplied of a commodity are determined by the intersection of its demand and supply curves. This is the demand and supply approach to economics. When extended to labour, the intersection of the demand and supply curves of labour is supposed to determine the wages per hour (the price of labour) and the number of hours worked (the quantity of labour). Therefore, an increase in the demand for labour relative to its supply is expected to raise the wage rate and a relative increase in supply of labour (say, from an increase in the working population commonly termed the demographic dividend) leads to a fall in the wage rate.

Classical economics, a distinct theoretical framework in economics, has a very different view of wages. It largely considers wages as an exogenous variable; that is, wages are not determined by market forces – demand and supply of commodities or of labour. Of course, temporary changes can be brought about by market forces. In the theoretical world of classical economics, wages are determined primarily by socio-cultural factors such as trade union strength, the collective notion of minimum wages for different occupations and the society’s views on trust, risk, etc. In this theoretical world, which to me, seems closer to the reality, an improvement in social institutions lead to an increase in subsistence wages. Wages, in this framework, has a subsistence (relatively fixed) component and a surplus (relatively flexible) component. Hence, classical economics allows for an increase in wages, in its surplus component, when GDP is rising on account of higher labour productivity.

A conflict is present in the distribution of GDP between workers and capitalists. Neoclassical economics eliminates this conflict by recourse to marginal productivity theory. By employing logically fallacious concepts (especially of capital), a theory of distribution has been erected where both labour and ‘capital’ are ‘justly’ remunerated. In this framework, trade unions distort the market and causes injustice! According to classical economics, the presence of strong trade unions and fair labour laws ensure that workers get a fair share of productivity gains, which will otherwise entirely go as profits of the capitalists. The Global Wage Report 2012/13 published by the International Labour Organisation (ILO) notes that in several countries wage rises have not matched the increase in employment and productivity (see especially p. 28).

There are enormous disparities in wage rates across the states in India, with Kerala paying relatively high wages. One reason for the high wages is the presence of strong trade unions. As per the Labour Bureau (as part of the Rural Labour Enquiry) report on ‘Wage Rates in Rural India’ for September 2012, the average daily wage rates for men for engaging in sowing in Gujarat is 132 rupees; in Kerala, it is 500 rupees; and in Tamil Nadu, it is 222.02 rupees. A carpenter in Gujarat is paid 233.33 rupees daily; in Kerala, he is paid 514.05 rupees and in Tamil Nadu, he is paid 388.6 rupees. The differences are starker with respect to unskilled labour: a male unskilled worker in Gujarat gets paid 109 rupees; in Kerala, he earns 411.32 rupees; and in Tamil Nadu, he earns 223.54 rupees. The corresponding wages for a female worker are: 101.71 rupees in Gujarat, 266 rupees in Kerala and 159. 76 rupees in Tamil Nadu. Note the gender-wage inequality in Kerala. Also, the economic condition in rural Kerala is significantly better than rural Tamil Nadu; therefore, the statistics will have to be interpreted with some restraint.

Subsistence wage, as a concept, has enormous theoretical and practical significance. In fact, the legislations pertaining to minimum wages in India ought to look at socio-cultural factors too, such as gender, caste, geographic location, kind of labour (formal vs. informal, rural vs. urban) and so on. The enforcement of minimum wages has been beset with difficulties as evident from a recent study (published in 2011) by Patrick Belser and Uma Rani; the proportion of salaried workers and the proportion of casual workers below the minimum wage at the national level is 25.3 and 50.6 per cent respectively. Discussions on and about subsistence wages, and by extension, on minimum wage legislations are much needed. Moreover, discussions surrounding subsistence wages can also result in more dignified definitions of poverty and minimum wages.

Malthus: The Scope of Political Economy

Posted by Alex M Thomas on 1st April 2012

In these difficult times we live in, what economics needs is perhaps, depth and not breadth. Unemployment, poverty, inflation, food insecurity, financial fragility, debt crisis, etc can be better understood and tackled by diverting increased resources (time and financial) in understanding the production, distribution, exchange and consumption of wealth. This blog post very briefly examines Thomas Malthus’s (1766-1834) view of political economy – its method, scope, uses and limitations.  For this purpose, I have used John Pullen’s definitive variorum edition of Malthus’s Principles of Political Economy published as 2 volumes by Cambridge University Press in 1990.

According to the Cambridge Advanced Learners Dictionary, ‘scope’ is defined as the ‘range of subjects covered’. In the context of political economy, scope refers to the range of subjects it covers. That is, the scope of political economy informs us about the sphere of analysis, the boundaries or limits, the kind of situations it describes and its applicability in the real world or, its relevance. Keeping in mind that mathematics played only a small role in political economy during Malthus’s time, let us see what his view of political economy is: ‘the science of political economy bears a nearer resemblance to the science of morals and politics that to that of mathematics’ (p. 2). Undoubtedly, morals played and still play an important role for interventions in the economy based on what we consider to be a ‘good society or economy’. And politics, distributional conflicts over income, land, natural resources and employment are integral part of any economy. Thus, it is important that political economy (and economics) takes into account these distributional conflicts when theorising or modelling an economy. However, for purposes of theory, these conflicts can be taken as given from outside economics (exogenous) or can be determined within economics, in the manner of behavioural economics.

It would not have mattered if political economy was/is not a very important branch of knowledge. Reminiscent of Keynes’s words, Malthus writes: ‘The science of political economy is essentially practical and applicable to the common business of human life. There are few branches of human knowledge where false views may do more harm, or just views more good’ (p. 12). But, Malthus wrote it more than a century earlier. (See also Sismondi’s words of a similar nature). Since Malthus viewed political economy to have significant practical applications, the complete title of his book reads ‘Principles of Political Economy Considered with a View to their Practical Application’. The editor, Pullen, gives us a bit more information on this matter. ‘This was apparently a lifelong concern. As a student at Cambridge in 1786 Malthus wrote to his father: ‘I am by no means, however, inclined to get forward without wishing to see the use and application of what I read. On the contrary I am rather remarked in college for talking of what actually exists in nature, or may be put to real practical use’’ (p. 291, Vol II; all other page numbers excepting this refer to Vol I).

Malthus understands that ‘To trace distinctly the operations of that circle of causes and effects in political economy which are acting and re-acting on each other, so as to foresee their results, and lay down general rules accordingly, is, in many cases, a task of very great difficulty’ (p. 12). Economic processes are caused by a multiplicity of causes and often not by a single one. Owing to this and because of his view of economics as a practical science, he maintained that ‘[t]o know what can be done, and how to do it, is, beyond a doubt, the most valuable species of information. The next to it is, to know what cannot be done, and why we cannot do it’ (p. 17). In other words, we must be very aware of the ‘scope’ of our knowledge.

Furthermore, if our objective is to understand the problems of unemployment and poverty, we must perhaps, as mentioned in the introduction, study in-depth the process of generation and distribution of wealth. I conclude with a statement by Malthus: ‘If we wish to attain anything like precision in our inquiries, when we treat of wealth, we must narrow the field of inquiry, and draw some line, which will leave us only those objects, the increase or decrease of which is capable of being estimated with more accuracy’ (pp. 27-8).
