Pierangelo Garegnani (1930 – 2011)

Posted by Alex M Thomas on 25th October 2011

On October 14, 2011, heterodox economics (in particular, classical economics) lost one of its warriors. This post attempts to summarise some of his key contributions towards economic theory. First and foremost, he was an economic theorist par excellence. He contributed to the famous (now, almost forgotten) capital theory debates in 1960s along with Piero Sraffa and Joan Robinson on his side and Paul Samuelson and Robert Solow on the other. Alongside others, he pointed out logical flaws in the marginalist conception of capital and its devastating effects on equilibrium. Basically, marginalist theory of value and distribution (in modern parlance, microeconomic theory) was shown to be logically inconsistent. Today, these debates hardly ever appear in economics textbooks because marginalist or neoclassical economics invented inter-temporal equilibrium to take care of capital-theoretic issues. Moreover, history of economic thought has been sidelined – through famous graduate economic programs and by preaching that history of economic thought is of no use to a “practical” economist, both in academia and in business.

Garegnani made significant contributions to the revival of classical economics on the foundations laid down by Piero Sraffa. In particular, Garegnani, through various journal articles (in Italian and English) resurrected the works of old classical economists – mainly Smith, Ricardo and Marx. More than Sraffa, perhaps, it is Garegnani who has aided the revival and resurrection of classical economics. His command over the history of economic thought with a special focus on old classical economists and ‘old’ and ‘new’ neoclassical economists (Walras, Wicksell, Hicks, etc) is evident from his clear exposition of their analytical structure.

Like ‘old’ classical economists, Garegnani’s interest has been to explain growth dynamics of an economy. This, he believed and also demonstrated that it is possible by drawing insights from Keynes and working on a classical (Sraffian) foundation. In this regard, Garegnani and his friends-colleagues-students have been quite successful in their analysis of capacity utilization, supermultiplier, role of wages, profits being a monetary phenomenon and so on.

Given the massive contributions made by Garegnani, it has been an honour for me to have been introduced to his work during my Masters in Economics at University of Hyderabad. It is one of the few Universities, in India and possibly, in the world, which still teaches classical economics as a distinct approach to understanding contemporary economies. I hope that more Universities begin to recognise the benefits of a pluralist education and start teaching classical economics as a distinct subject.

Urbanization in India: What does it mean?

Posted by Alex M Thomas on 26th August 2011

 

In the recent past, there have been a lot of discussions and commentaries on the merits of urbanization in India. In addition to this, we also hear about the poor, rather pathetic, living conditions of migrants who work in urban spaces, there are pressing environmental concerns especially regarding air and water pollution, public transport is in a disarray, etc. The latter concern has led to the rise of ‘new’ areas of learning and research such as urban studies, urban economics, urban ecology, urban sociology and urban planning. These are extremely important areas of learning considering the fact that urban centers attract both labour and capital. This blog post tries to understand some economic issues relating to the process of urbanization that is taking place in India. In particular, we seek to understand the limits of urbanization and in the process we try to know what it means to achieve economic growth.

According to the World Bank, “Urbanization is not a side effect of economic growth; it is an integral part of the process.”  McKinsey states that “Urbanization is critical to India’s development.” Further, Ministry of Urban Development, Government of India notes that “It is important to note that the contribution of urban sector to GDP is currently expected to be in the range of 50-60 percent. In this context, enhancing the productivity of urban areas is now central to the policy pronouncements of the Ministry of Urban Development. Cities hold tremendous potential as engines of economic and social development, creating jobs and generating wealth through economies of scale. They need to be sustained and augmented through the high urban productivity for country’s economic growth. National economic growth and poverty reduction efforts will be increasingly determined by the productivity of these cities and towns.”

From the above excerpts, some important assumptions (or rationales) for promoting urbanization can be understood.

(1)    Economic growth is synonymous with urbanization.

(2)    India has to urbanize in order to attain economic growth and development.

(3)    Urban spaces need to be promoted because they generate about 50% of the Indian GDP.

(4)    Cities are potential engines of economic and social development.

 Economic growth

In a macro sense, economic growth refers to the sustained growth in national output – GDP. However, for policy purposes it is important to look at per capita GDP. This is a proxy for looking at how much on income an average person possesses. The objective of economic growth (and economics) is to ensure that all individuals are employed (who seek work), have adequate food, have access to drinking water, transport, etc. In no way should we consider the objective of increasing GDP to be our aim. It is a necessary means to an end- better life.

Urbanization is understood as an increase in the population of urban spaces. This also means that there is a growth in employment, capital inflow, infrastructure, etc. In turn, such large increases in population will result in an increased pressure on resources – water, space, housing, transportation, office space, air, etc. Communication seems to be the only one which has relatively negligible supply problems.

Given this, how can the Central Government or Planning Commission argue that urbanization is the way to go forward? This means – fatten urban spaces and neglect rural areas! Both, as we know, are not desirable. Fattened urban spaces will present a whole new set of issues to tackle with; neglecting rural areas will mean that agriculture and those dependent on agriculture (around 60% of India) will not be encouraged. Clearly, this does not increase the well being of majority of Indians. More importantly, it is illogical and unwise to argue that urbanization is (or leads to) economic growth. Yes, it leads to economic growth, but only in a very superficial manner and not in any substantive way.

India: Rural and Urban

As per Census 2011, 69 % of Indians live in rural areas and only 31 % in urban spaces. It seems to be the case that the policy makers are interested in improving the “urban spaces”. This does not necessarily include improving the living conditions of the majority of Indians. It is strange how language plays a dividing role too: urban habitats versus rural areas! It is true that the urban sector contributes roughly around 50% of India’s Net Domestic  Product (NDP). The remaining comes from rural India which comprises majority of the populace. As for agriculture, rural areas contribute 94% (for the year 2004-05) of total agricultural output. So, if urban areas are targeted at the cost of rural areas, those employed in agriculture, which is a very difficult occupation, are going bear the brunt.

It is strange that the Government and policy makers (including private think tanks) argue that cities are potential engines of economic growth, when 60% of Indians depend on agriculture for their livelihood which is mainly located in rural areas. This tendency of policy making to favour any method which just boosts the numerical value of GDP without any qualitative change must be stalled. By qualitative change, I refer to improvements in quality of life – food, shelter, education, water, health and so on.

According to a recent paper (July-August 2011) by Gilles Pison in Population & Societies, India is expected to become the most populous country by 2050 and will overtake China. Yes, we have heard that India has been blessed with the demographic dividend; but we must remember that it is no dividend unless there are employment opportunities, and they should not just be in urban spaces. This paper also notes that India records the highest number of deaths under age one – 13,96,000.

Hence, the Planning Commission has considered it imperative that the next 5 Year plan will include urbanization as a key challenge. This, however, is a myopic strategy and especially because of the neglect of agriculture. In addition, employment generation should be the key challenge. Jayati Ghosh also argues in a similar fashion in a recent article of hers. She points out that “The number of urban settlements has increased from 5161 in 2001 to 7935 in 2011, an increase of 54% that dwarfs the 32% growth in urban population.” This means that urban statistics have swelled up because of a reclassification and not mainly because of rural-urban migration. This key information poses further problems for policy makers; actually, it poses problems only for the ‘concerned’ policy makers!

Conclusion

To sum up, it would be disastrous to formulate policies which targeted the urban spaces at the cost of rural areas. The objective of economic policies must be to improve the well-being of the people and not to increase the percentage of GDP by a few points! In fact, even in France and Europe, when the process of urbanization began in the early 18th century, agriculture was neglected. However, a group of economists known as Physiocrats argued that agriculture cannot and should not be neglected as it will lead to a downfall of the economy (see more). It is time that we realized the interdependence present in the economy between rural and urban areas and also high time we acknowledged the significance of creating employment opportunities to the majority of the population.

Economics: The Study of Commodities

Posted by Alex M Thomas on 18th December 2010

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.
