Kunkel on David Harvey and Robert Brenner: Demand, Profits and Employment

The link between demand and profits, and consequently employment, is visible in the works of the classical economists and Marx. In this blog post, we set out the link between these variables by way of assessing the contributions of David Harvey and Robert Brenner, as narrated and presented by Benjamin Kunkel in his 2014 collection of essays, all previously published – Utopia or Bust: A Guide to the Recent Crisis (and not on the basis of Harvey’s and Brenner’s original texts).

Karl Marx has already presented us with the possible reasons for the occurrence of crises in capitalist economies. Kunkel treats these crises as profitability crises (pp. 34-6); they can occur because of (1) profit squeeze, (2) a rising organic composition of capital, and (3) underconsumption. A capitalist crisis causes activity levels to drop and results in wide-spread unemployment. The three factors mentioned above reduce the profits of capitalists, consequently affecting their decision to produce and therefore adversely affecting their decisions to employ workers and purchase capital goods. The first – a profit squeeze, is self-explanatory, but its causes need not be. A rise in real wages, ceteris paribus, leads to a decline in the rate of profit. The organic composition of capital, according to Marx, refers to the ratio between constant capital and variable capital. Constant capital refers to the investment expenditure on plant, machinery, tools and other constant/fixed capital. Variable capital refers to the investment expenditure relating to the workers – wage costs, training costs and the like. When the ratio of constant to variable capital rises, or equivalently, when the organic composition of capital rises, the rate of profit (the ratio between profits and capital advanced) falls. The third cause is underconsumption, by workers. This occurs, by definition, since the value of the real wage is less than the value they add to the commodity. In Marxian terms, this difference measures the surplus-value that the capitalists extract from the workers.

Strong bargaining power on the side of the workers can generate a rise in the real wages; although, note that the terms of agreement are usually set in money wages. The rising organic composition of capital is not a law, but a contingent proposition. As for underconsumption, if workers’ wages are just sufficient for their survival, it can result in goods lying unsold and therefore affect capitalist profits. To put it differently, there arises a gap between aggregate supply and aggregate demand. This, according to Harvey, places a ‘limit to capital’.

What can possibly eliminate underconsumption, a facet of capitalism, a consequence of positive capitalist profits and a cause of economic crisis? Harvey points out that it is credit which eliminates this cause, at least, temporarily.

‘Any increase in the flow of credit to housing construction, for example, is of little avail today without a parallel increase in the flow of mortgage finance to facilitate housing purchases. Credit can be used to accelerate production and consumption simultaneously.’

(Harvey; as quoted on p. 32)

But, Kunkel cautions us that even if credit can fund the required aggregate demand, changes in income distribution brought about by the struggle between workers and capitalists will affect the aggregate equilibrium, and will render it unstable.

‘If there exists a theoretical possibility of attaining an ideal proportion, from the standpoint of balanced growth, between the amount of total social income to be reinvested in production and the amount to be spent on consumption, and if at the same time the credit system could serve to maintain this ratio of profits to wages in perpetuity, the antagonistic nature of class society nevertheless prevents such a balance from being struck except occasionally and by accident, to be immediately upset by any advantage gained by labor or, more likely, by capital.’ (p. 37)

It is not entirely clear what mechanisms and processes Kunkel is referring to when he makes the above claim about income distribution rendering the equilibrium unstable. Indeed, if the available credit is not sufficient to counter the depressed wages and high profits, the aggregate equilibrium will be unstable.

Another route through which capitalist crisis can be postponed is via long-term infrastructural projects. ‘Overaccumulated capital, whether originating as income from production or as the bank overdrafts that unleash fictitious values, can put off any immediate crisis of profitability by being drawn off into long-term infrastructural projects, in an operation Harvey calls a “spatio-temporal fix”’ (p. 39). Here again, it is contingent on the extent to which the workers gain from the surplus generated by these projects, both in the short and long-term. For example, the employment guarantee programme in India creates infrastructure as well as provides employment and wage income.

‘So what then are the “limits to capital”’ (p. 41)? ‘Keynesians complain of an insufficiency of aggregate demand, restraining investment. The Marxist will simply add that this bespeaks inadequate wages, in the index of a class struggle going the way of owners rather than workers’ (p. 43). Inadequate wages, as previously indicated, does generate demand deficiency. To that extent, Marx’s and Keynes’s account of capitalist crises are very similar.

Kunkel points out the role of environmental degradation, a consequence of capitalist drive for profits, in capitalist crises. ‘Already three-concentrations of carbon in the atmosphere, loss of nitrogen from the soil, and the overall extinction rate for nonhuman species-have been exceeded. There are impediments to endless capital accumulation that future crisis theories will have to reckon with.’ This can be easily integrated into the theories of output and of growth, as Ricardo’s diminishing returns to land, has been. Environmental depletion poses constraints on the supply side primarily and for economic growth, positive capital accumulation is necessary. Therefore, environmental degradation poses a strong constraint on the supply side of the economy.

Robert Brenner made a ‘frontal attack on the idea of wage-induced profit squeeze’ (p. 87). As Kunkel puts it, ‘increased competition exerted relentless downward pressure on profits, resulting in diminished business investment, reduced payrolls, and-with lower R&D expenditure-declining productivity gains from technological advance. The textbook result of this industrial tournament would have been the elimination of less competitive firms. But the picture drawn by The Economics of Global Turbulence is one of “excessive entry and insufficient exit” in manufacturing’ (p. 87). In other words, the profit squeeze was not wage-induced.

Marx’s realization crisis finds a mention in Kunkel’s essay on Brenner too. ‘If would-be purchasers are held back by low wages, then the total mass of commodities cannot be unloaded at the desired price. Capital fails to realize its customary profits, and accumulation towards stagnation’ (p. 91). This is the crucial point. Capital has to realize its customary profits, a magnitude which includes a return on risk and undertaking (a return on enterprise, if you like) and the rate of interest. Capital that is invested in a riskier enterprise is expected to provide higher returns. The search for demand (or markets) is not new. Mercantilism was precisely that. More recently, ‘[i]n Germany and Japan, and then in China, catering to external markets won out over nurturing internal demand’ (p. 94) However, currently, there are signs of a reversal as external demand is falling, and net-exporting countries are reorienting towards domestic demand (p. 95).

But, what is to be done? According to Kunkel, ‘[g]lobal prosperity will come about not through further concessions from labor, or the elimination of industrial overcapacity by widespread bankruptcy, but through the development of societies in which people can afford to consume more of what they produce, and produce more with the entire labor force at work’ (p. 98). Kunkel rightly advocates better wages and the full-employment of labour. For, it is only such a society which can afford its citizens with a dignified and economically comfortable life. As a matter of fact, ‘[m]ore leisure or free time, not less, would be one natural-and desirable-consequence of having more jobs’ (p. 103). A similar call is visible in Robert & Edward Skidelsky’s How Much is Enough? Money and the Good Life published in 2012. We urgently need an economic architecture where goods can flow easily across regions, workers earn good wages, capital earns its customary profits, labour is fully employed and the environment is respected. In working towards this goal, it is necessary to possess an accurate understanding of the link between demand, profits and employment.

Wages in Economic Theory and Reality: Some Issues

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.
