Economics: The Study of Commodities

The study of commodities has been central to economic theory. Mercantilists considered gold, a commodity to be wealth. Later economists argued that an increase in commodities, both agricultural and manufactured, implied an increase in wealth. The increase in the production of commodities is still the most widely used indicator of economic growth/progress. This indicator is none other than the real GDP. In 1985, Amartya Sen published a book titled Commodities and Capabilities. In this work, Sen challenges the dominant view in economics regarding the role of commodities, i.e. he maintained that an increase in commodities cannot be taken as the sole factor in assessing economic development. Sen emphasised the importance of examining capabilities, which subsequently led to the creating of the Human Development Index (HDI). This post discusses the rationale behind economists’ obsession with commodities. It also examines Sen’s critique of commodities and how his (Aristotelian) concept of capabilities differs from it. This post concludes by arguing for a strengthening of classical economics, which studies the production, distribution, exchange and consumption of commodities, for the considerations of ethics can be easily integrated into this approach.

Economics as a distinct form of inquiry begins with the works of Sir William Petty in the 17th century. Petty was interested in assessing the comparative wealth of England and Ireland. Some of the indicators he chose were the number of houses and population. The idea behind this being that a surplus of food results in more population and therefore more houses. Having a large population was considered to be beneficial to the state. His successor, Richard Cantillon, an economist par excellence, pointed out that wealth of a state is reflected in the quantity and nature of commodities it produces ‘ necessities, comforts and luxuries. This brief historical excursus is to point out the nature of economic inquiry, which is essentially an analysis of quantities and prices. Examples of quantities are employment, income, exports, investment, money supply, etc. Examples of prices are WPI, interest rates, foreign exchange rate, commodity prices, share prices, etc. That is, an analysis of commodities is an examination of quantity and price at the same time. Therefore, an analysis of commodities subsumes an examination of their production, distribution, exchange and consumption. Production includes the structure and relations of production; distribution pertains to the process and mechanism through which the incomes/surplus from production is divided among its participants; exchange refers to the mode and institution through which commodities are sold; finally, consumption illuminates the channels through which consumption of commodities aid production in the next period and how production in the current period aids current consumption. Thus, classical economists such as Petty, Cantillon, Quesnay, Smith and Ricardo were interested in the theory of production, distribution and exchange of commodities. Their interest was motivated by the need to find out ways of improving the general well-being of their respective societies.

According to Sen, the kind of analysis posited above looks at opulence as the sole indicator of economic development. A shift in economic analysis came about in the 1870s with the emergence of marginal analysis, independently developed by Jevons, Walras and Menger. Terms such as utility, choice, scarcity, margins, etc made inroads into economics. In fact, standard microeconomics texts are nothing but a combination of Walrasian and Marshallian economics. In any case, the maximization of utility began to be seen as the objective of individuals, for attaining economic progress. The internal justice of free markets was imbued to this form of economic analysis. Based on utilitarian principles, the maximization of utility by individuals was seen as a way to improve human well-being and welfare. This conception of development, according to Sen, emphasised the role of utility.

Both the above mentioned analyses, according to Sen, deal with ‘the relation between commodities and people’ (p. 1). The former approach argues for more commodities which leads to more production, which raises the incomes of the people and hence their consumption. The latter analysis points out that ‘more is better’ and hence availability of more commodities imply more utility. The idea of ‘more is better’ is intricately connected with their idea of economics, as a science of choice. Economics, for marginal/neoclassical economists, refers to the allocation of scarce resources amongst alternative uses, as Lionel Robbins points out. For Sen, both these analyses are limited, since they do not address the heterogeneity in the capabilities of different people, which leads to ‘a confounding of the state of a person with the extent of his or her possessions’ (p. 16). It is precisely this argument of Sen developed in his 1985 book which widened the scope of mainstream economics. I write mainstream economics because for classical economists, economics or political economy formed only one way of looking at growth/progress/development. For classical economists, as pointed out earlier, an analysis of production included the state or condition of the producer. The best example of this form of theorising can be found in Marx, the last of the early classical economists. However, with the advent of marginal analysis, the analyses of the structure of production took a backseat. The sphere of exchange came to the forefront and along with it the explanation of the formation of all kinds of prices and quantities through the apparatus of demand & supply.

It is interesting to note that the idea of capabilities has been intrinsic to classical economics. As mentioned earlier, an increase in the production of commodities translates into an increase in income generated. In contrast with neoclassical economics, the economic processes is visualised in a circular way as opposed to a one-way street. One needs to look into the structure of production to find out to whom (which class) this increase in income accrues (theory of distribution). However, the manner in which Sen develops his capabilities approach is rooted in mainstream/neoclassical economics ‘ via the sub-domain of welfare economics (See Benicourt 2002 and Omkarnath 2007). Although, Sen deserves credit for bringing back humanitarian concerns into the discourse of neoclassical economics. Omkarnath further points out that the capabilities approach rooted in the Walrasian tradition is static in nature, for it mainly concentrates on the formation of capabilities. Whereas, classical economics has numerous insights on the relation between capabilities and commodities. This sort of analysis calls for a careful examination of the structure of production, distribution and exchange present in various economies in the classical political economy tradition, which has more scope for including social, cultural and political factors as well as ethical concerns.

Economic Growth in India: Some Considerations

It has been pointed out earlier in this blog that economic growth cannot be understood by merely looking at the rate of growth of GDP; and that an adequate explanation of economic growth needs to incorporate the ‘structure of economic growth’. This post builds on the idea that ‘structure of growth’ is of paramount importance by pointing out certain important aspects of growth, which have been put forward by Pulapre Balakrishnan in his new book (OUP, 2010), Economic Growth in India: History and Prospect.

Balakrishnan’s book questions several aspects of mainstream theorising on growth. Firstly, he emphasises that fact that, there can be no ‘universal model of growth and development’ (p. 29). Though, this point is very obvious to most people, economists still try to develop ‘scientific models’ which are general enough so that the varied growth experiences of different countries can be explained. In particular, the fact that there is no universal model has been shown by the growth experiences of countries like Japan and China. Maybe, unfettered competition and self-interest work in certain countries. In others, a one party system might work. Or, democracy coupled with active state intervention might be the solution for a few. The growth trajectory of a particular economy depends on its history, its people, its land, its politics, its institutions, its culture, its government, its media and so on. For example, it would be foolish to provide disproportionate sops and subsidies to the service sector, when majority of the population depend on agriculture. Whatever be the model of growth and development, it is of utmost importance that the inhabitants or the populace of that country has enough food to eat, proper clothes, access to safe drinking water, a proper house, a job, etc. In other words, the minimum requirements (which is historically, socially and culturally determined) of the inhabitants need to be met.

The recent past has witnessed a lot of debates on the juncture at which the Indian economy structurally transformed. Several years have been identified as break-points depending on the base year adopted, the kind of statistical test chosen, the nature of data, etc. There has been no consensus. Some identify 1991 as the point of change. Others argue that the growth process had begun as early as the late 1970s. Not surprisingly, these results also depend on what the economists think the role of the government is (or the role of the markets). However, Balakrishnan argues that the time period 1900 to 2005 ‘may be seen as setting the minimum agenda for an investigation of growth in the country’ (p. xxvi). This assertion is a noteworthy one, for it can aid in understanding the role of the government as well as the role of the market (understood as the competitive mechanism) in the economic growth process for over 100 years.

An examination of the process of growth from 1900 onwards is certainly a very difficult task. However, the merits of the hard work outweigh the costs. Systematic data collection in India begins from only around 1950s. However, by making use of the scattered accounts written by various travelers, historians, fiction writers, etc and from English archives, port records, and others, one could construct a narrative of the growth process. Unfortunately, most of the growth narratives of the Indian growth stress only on ‘numbers’. An analytical growth narrative, according to Balakrishnan, offers a better mode of capturing growth. It ‘may be seen as a theoretically informed empirical analysis of growth in a country over a specified period.’ (p. 36) However, this mode of analysis can become narrow if the ‘theory’ is only taken from economics. If the theory can be expanded to take in insights from related disciplines like history, political science, sociology and anthropology, the analytical growth narrative can provide a rich and comprehensive account of growth.

Such a growth narrative would also mean a shifting of research from the growth accounting based on production function to a more holistic one, which takes into account the structure of the Indian economy ‘ the divide between rural and urban, between men and women, between agriculture and services, between organised and unorganised, between English-educated and illiterate, between those who have access to computers and those who do not, etc. For, growth accounting based on production function suffers from numerous logical and conceptual issues. This method assumes that the contributions made by labour and capital (means of production) are independent, which in reality and accounting wise, is difficult to accept. This method also gets into trouble when it tries to incorporate rapid technological advancements.

From the preceding discussion, it is clear that there can be no universal model of economic growth and development. And, until a more comprehensive understanding of economic growth is presented by economic theorists, the urgency to find out a break point is of no use. Also, economic growth is a process which takes place over time; hence, a long term perspective is necessary to understand growth and to put forth the determinants of growth. Also, it is time to give up growth accounting based on the aggregate production function. To conclude, it is time that growth narratives are also put forth by other social scientists. And, why is it that discussions on economic growth remain the prerogative of the economists alone’

The Indian Constitution and Human Dignity: for Economists

The field of law and economics is a glamorous one with economists such as Ronald Coase, Gary Becker and Richard Posner. It was Coase who provided the inspiration to law and economics through his introduction of ‘transaction cost economics.’ And Becker was the one who extended the domain of economics to virtually any social phenomena. Issues such as law, crime, marriage, family, etc came to be studied by economists. Although, the tools used never varied. It was the same old microeconomic baggage of neoclassical economics. Suddenly, neoclassical economics started feeling successful all over again. Their theory of value and pricing started explaining various social and cultural processes in the economy. However, this post is not a commentary on law and economics that is practised. For an excellent commentary on its origins and methodology, see the article by William Davies ‘Economics and the ‘nonsense’ of law: the case of the Chicago antitrust revolution’ in Economy and Society published in 2010.

The content of this post certainly falls under the label of law and economics. However, this post discusses certain aspects of the Constitution of India in the the light of economic policies undertaken-that of liberalization. The quotations in this post are from Dr. Durga Das Basu’s Introduction to the Constitution of India, reprinted in December 2009.

Economic Justice

The banishment of poverty, not by expropriation of those who have, but by the multiplication of the national wealth and resources and an equitable distribution thereof amongst all who contribute towards its production, is the aim of the State envisaged by the Directive Principles. Economic democracy will be installed in our sub-continent to the extent that this goal is reached. In short, economic justice aims at establishing economic democracy and a ‘Welfare State’.

The idea of economic justice is to make equality of status meaningful and life worth living at its best removing inequality of opportunity and of status-social, economic and political.

That is, an increase in growth rate is seen as the way to banish poverty. This principle is certainly based on the idea that growth trickles down. As has been witnessed in India, all that liberalization has achieved is ‘jobless growth’. Hence, the need for policy documents to shout for ‘inclusive growth’.

Now, all those who contribute to wealth by being producers are supposed to be compensated. It is on this class, that the burden of development falls. For, they do not have the adequate social and economic voice to demand for ‘just distribution’.

Can India claim social justice just by making opportunities equal’ Equal opportunities perform their function only in an already just and equitable society, and not in countries where inequality of income and wealth is so skewed. Thus, an active intervention is necessary at the level of production as well as distribution of GDP.

Nehru’s idea of Socialism is that ‘every individual in the State should have equal opportunity for progress.’ However, this idea cannot hold any water until the institutions in the State are examined- judiciary, executive, military, private enterprise, unorganised sector, etc. For instance, some groups of people are exploited as producers, where they are paid less than minimum wages. Therefore, as a consumer, they get exploited as well. This then passes on to their access to health, schooling, sanitation, housing, and so on.

Individual Liberty

The Preamble, therefore, says that the State, in India, will assure the dignity of the Individual. ‘All citizens men and women equally, have the right to an dequate means of livelihood, just and humane conditions of work, and a decent standard of life and full enjoyment of leisure and social and cultural opportunities.’

When economists and policy makers talk of ‘inclusive growth’, it is the dignity of the individual which is at stake. Often, India’s characteristics such as high reliance on agriculture, a large percentage of unorganised sector, immobility of labour and the like are labelled as detrimental to India’s growth and development. One cannot help but ask: Whose growth’ Such perceptions by the academia are largely a result of the manner in which human beings figure in micro and macro economics. If you take a moment to think about it, you will realise that poor people-who are a heterogeneous group- is absent from our theoretical edifice. Why’ Who are we analysing’ And to discuss poverty, we have created a sub-discipline called ‘development economics’.

In any case, human dignity appears to be of lesser importance than the computation of growth rates using yearly and quarterly data. We are satisfied to decipher whether stock market exhibits volatility or not’ Or whether market A is co-integrated with market Z. Does this satisfaction come from the fact that stock market data is easily available’ What about the farmers, the child labourers, the migrant labourers who are forced to leave their place and family, of street vendors, and all the others who actually engage in production’

Until dignity of human life features implicitly or explicitly in economics, it will continue to be a lifeless endeavour. Sadly enough, we are taught economics is the study of choice’ Whose choices’ Those who have the ability to choose’ It is time we discarded such economics and re-visited economists such as Adam Smith, Joan Robinson, Amit Bhaduri, and others whose works show a concern for humans.

Model Building and Planning in India

Ever since the First Five Year Plan, we have utilised models in order to channel resources for achieving objectives of higher growth, establishing strong capital base, strengthening import substitution, reducing poverty, increasing foreign exchange resources and so on. The early plans made use of Harrod-Domar model and the Feldman-Mahalanobis models. The models used for planning purposes were largely taken from economic theory, which were then adapted (hopefully) by the Planning Commission. Owing to changes in the structure of the Indian economy, the nature of modelling has also undergone various alterations. This post highlights certain issues in the macro-modelling that was done for the 11th Five Year Plan, chiefly based on the publication by the Planning Commission Macro-Modelling for the Eleventh Five Year Plan of India edited by Kirit S Parikh.

It is incorrect to argue that planning in India has become redundant after the 1991 reforms. These reforms provided freedom to the firms with respect to what to produce and how to produce them. As the recent global financial crisis has shown, unregulated finance can lead to unfavourable outcomes for the financial as well as the real sectors of the economy. Also, significant divergences in income and wealth are being reported. This is the case, especially in India which is home to some of the richest and poorest people in the world. As Parikh writes, ‘As long as disparities in income, endowments and wealth persist, access to public goods and services is uneven and infrastructure paucity is there, we need active government policy. We need planning.’ [Planning Commission 2009, 16]

The 11th Five Year Plan’s goal is to have ‘Faster and More Inclusive Growth’. The basis of this goal is that the growth of GDP is treated as a necessary and almost sufficient condition for improving livelihoods. We know that markets exclude those without adequate purchasing power. And growth in GDP mainly results in an increase in the extent/size of the market. Unless appropriate systems are in place, ‘trickle down’ does not take place. Hence, an outline of how ‘inclusive growth’ can take place needs much greater attention. And it is disappointing to see that employment generation is not considered as a central objective. For the first time, the inputs of the 11th Five Year Plan have been provided by a ‘modelling forum’. The forum consists of researchers from NCAER, IGIDR, IEG and ISI Bangalore apart from the in-house team of the Planning Commission.

A formal model is constructed for the purposes of planning because it makes the assumptions transparent, ensures consistency and provides insights into the inter-relationship between various actors and sectors in the economy. These models in turn borrow concepts, categories, functional relationships and links from the paradigms in economics. The paradigms that have influenced modellers, according to Parikh are Input-Output, Walrasian, Neoclassical, Keynesian, Structuralist, Vector Auto Regression/Error Correction, New Neoclassical and Dynamic Stochastic General Equilibrium. The most obvious drawback of this classification is the mix-up of paradigms with tools of economics. For instance, IO framework, VAR models and DSGE models are only tools. For our later exposition, it would be helpful to point out the important characteristics of each of these paradigms/tools.

Input-Output: Usage of inputs in fixed proportion

Walrasian: Optimising behaviour of economic agents

Neoclassical: Pricing through supply and demand mechanism and full employment at prevailing wage rate

Keynesian: Underemployment equilibrium

Structuralist: Imperfect markets and incomplete monetization of the economy

Vector Auto Regression: All variables depend on lagged values of all variables and data speak for themselves

New Neoclassical: Microeconomic foundation of macroeconomics- importance of information, expectations and contracts

DSGE: Forward looking and optimising economic agents

In the modelling for the 11th Five Year Plan, six different models with different analytical approaches have been used. The models are a) Perspective Planning Division’s In-house Model, b) A VAR/VEC Model from ISI, Bangalore, c) A General Equilibrium Model from IGIDR, d) An Econometric Model from IEG and e) Macro-Econometric Model of NCAER. The various model scenarios show that the direction of policy shocks are similar ‘though the structure and philosophy of the models are different’. However, this is not such a shocking or an interesting revelation. For everybody knows that oil price shocks have a negative impact on the GDP growth rate and that the global slowdown affects the GDP adversely. The only result of interest is that of an increase in NREGs by 1% of GDP. This will result in an increase of around 0.35 to 0.5 GDP percentage points. However, it must be noted that this is based on ‘a general equilibrium model in which it is assumed that the adjustments to the new equilibrium are completed in one year. Thus, the impacts may be overstated as in reality this may not be the case’.

Overall, it seems that the assumptions of the various models are far from our Indian reality. There is no attempt at including the unorganised sector. And it is very clear, from the recent evidences from neuroeconomics, experimental economics and game theory that individuals are not rational optimizing machines. Instead, we are more moved by social concerns and we exhibit a pro-social behaviour which is norm-based. There is no explicit move to analyse employment generation. Nor is there the necessary focus on agriculture. It is stated that agriculture needs to grow by 2.4 % to 4 % so as to achieve 9% GDP growth rate. One cannot help but wonder whether the objective of economic planning in India is only about the GDP growth rate! And as to the use of VAR models, the generators of the model argue that since there is ‘no real basis to say which variable is endogenous and which is exogenous’, they adopt a ‘general equilibrium approach, where everything (except rainfall, of course) depends on everything else.’ [Planning Commission 2009, 88] An easy route indeed!

This publication by the Planning Commission is a must read for all those who are interested in understanding the Indian policy making. Also, it provides the crucial link between policy and theory. Hence, making the study of economic theory very significant, especially for policy makers. It will also be of interest to students and practitioners of time series methods using the VAR framework.
