Pierangelo Garegnani (1930 – 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.

James Steuart, Strange(r) Economists and the Indian Economy

 

Inflation has been portrayed as the biggest challenge faced by Indian policy makers and its Central Bank, Reserve Bank of India, in recent times. The Chief Economic Advisor to the Government of India and Professor of Economics at Cornell University, Kaushik Basu, recently presented his professional views on inflation ‘ understanding and management, at the First Gautam Mathur Lecture on 18 May 2011. This is currently available for download as a working paper at the Ministry of Finance website. Various excerpts from this paper have made its way in some English newspapers and TV media. I will comment on this paper at length on a later date. Reading Basu’s paper makes me wonder whether monetary economists or other policy makers know what India is, who Indians are and what Indians actually do. In more abstract terms, do economists know the structure of the Indian economy’ Do they know what motivates Indians’ Is it primarily region, class, caste, religion, gender, education, self-interest, compassion, sympathy, fame, status’ Although, to be fair to Kaushik Basu, he asks the RBI not to experiment and not to put up a fa’ade of knowledge (which he frequently does). Without having a clear understanding of, what the 18th century economist James Steuart calls, ‘the spirit of a people’, it is impossible to formulate effective policies. Moreover, the focus on employment generation has completely given way to inflation stabilisation, using sophisticated econometric techniques. Therefore, this blog post revisits James Steuart’s views on how ‘the spirit of a people’ influences economic engineering. In the Indian context, the consequences of monetary intervention might not be those which are depicted in conventional models of inflation.

Sir James Steuart (1713-1780) published An Inquiry into the Principles of Political Oeconomy in 1767 which was and has been overshadowed by Adam Smith’s Wealth of Nations published in 1776. Steuart acknowledged the importance of devising context-specific economic policies. However, we must realise that context-specific economic policy is not antithetical to general economic theories. In other words, proposing economic theories and models of a general nature is not inherently a problem; but, when applied blindly, they cause havoc, which is often supressed in very clever ways. Steuart writes:

‘Every operation of government should be calculated for the good of the people. . .that in order to make a people happy, they must be governed according to the spirit which prevails among them’ (p. 21).

An ignorance or lack of understanding of this ‘spirit’ can have disastrous consequences. We see some of them in the worsening urban-rural inequality, falling of inflation-adjusted per capita incomes in interior villages [EPW, 2011], agricultural distress and forced migration [P Sainath, The Hindu, 2011]. One of reasons why such skewed policies are implemented is because of the rationale provided by ‘pure economic theory’, which Basu seems to praise for its scientific rigor and [semblance of] truth. To be clear, ‘pure economic theory’ is something which Steuart was against because it assumed a certain ‘spirit’ and claimed to be universal thereby neglecting important specificities and characteristics pertaining to individual economies.

For Steuart, ‘the spirit of a people is formed upon a set of received opinions relative to three objects; morals, government and manners: these once generally adopted by any society, confirmed by long and constant habit, and never called in question, form the basis of all laws, regulate the form of every government, and determine what is commonly called the customs of a country’ (p. 22). That is, education, religion, region, caste, gender, etc would significantly affect the ‘spirit’ of India. Also, important characteristics such as the percentage of Indians employed in agriculture, in unorganised manufacture, in self-employment, in rural areas, using informal sources of finance, who are socially poor (less than 100 rupees a day), who actually invest in stock markets, who read English newspapers and so on affect the outcomes of economic engineering. Not paying heed to these significant characteristics is the same as formulating an inappropriate policy. Let me highlight once instance. The RBI conducts Inflation Expectations Survey to estimate how the expectations of the Indian populace change over time and this result forms an input into monetary policy making. Despite this, the RBI did not survey any Indian living in rural areas; they seem to neglect and forget the fact that the main producers live in rural areas and their chief occupation is agriculture! This certainly deserves to be questioned. Policies should not be formulated ‘at any point which regards the political oeconomy of a nation, without accompanying the example with some supposition relative to the spirit of the people’ (p. 23). If the ‘spirit of the people’ is not taken into account, as the example above indicated, such policies could prove to be harmful. This also calls for greater dialogue between economists and other social analysts (sociologists, cultural theorists, political scientists, anthropologists, social workers, etc) when engineering nation-wide socio-economic policies. Hence, Steuart writes that ‘in every step the spirit of the people should be first examined’ (p. 25).

Often, the attitudes of policy makers indicate how much their academic knowledge is irrelevant for practical economic and social problems. The reliance on ‘pure economic theory’ is nothing but an intellectual looking, mathematically replete and made-difficult-to-understand version of free markets, because efficiency and rationality are our new gods! As Keynes writes in his preface to The General Theory, ‘the difficulty lies, not in the new ideas, but in escaping from the old ones, which ramify, for those brought up as most of us have been, into every corner of our minds.’ Today, these ‘old ideas’ are not only fashionable and ‘scientific’ (and often unsuited to India), but they are also communicated relentlessly to the new generations through schools and universities. In conclusion, it is scary to realise that India’s policy making is done by those who are ‘strangers’ to the Indian realities. Steuart warns us that ‘when strangers are employed as statesmen, the disorder is still greater, unless there be extraordinary penetration, temper, and, above all, flexibility and discretion’ (p. 27).

V K R V Rao: The Entrepreneur Economist

The contents of the following post was written over a year ago for an in-house publication. Hence, the tone of the post is different from that of the rest. And since we are more enamoured by American economists these days, this is a timely post, which talks of one of the many great economists India has seen.

V K R V Rao founded Delhi School of Economics (DSE), Institute of Economic Growth (IEG) and Institute for Social and Economic Change (ISEC). These institutions were established so as to impart economics education in India, which would compete with world-famous institutes like LSE, Cambridge, etc. He was also instrumental in establishing the Indian Council of Social Science Research (ICSSR). Apart from establishing these institutes, Rao also served in various administrative positions – Planning Commission Member, Union Cabinet Minister first for Shipping and Transport and then Education and Youth Services. For the services rendered, he was awarded Padma Vibhushan in 1974.

Rao completed his Master’s in economics from Bombay University, where he worked on the taxation of income in India for his Master’s thesis. He then moved on to Cambridge to pursue his PhD, where he became a student of Keynes. For Rao, economics was a social science that would aid in improving the human condition. In Cambridge, he discovered that the tools of government intervention could aid in fulfilling the objective of economic as well as social betterment. And it was Colin Clark who stimulated his interest in statistical demography and national income accounting. However, as Shigeto Tsuru points out in his review of Reflections on Economic Development and Social Change: Essays in Honour of Professor V K R V Rao by C H Hanumantha Rao and P C Joshi published in 1979, Rao had insisted that ‘the blind application of Keynesian formulae to the problems of economic development has inflicted considerable injury on the economies of underdeveloped countries.’ For Rao, economic theory was only a servant of economic policy.

There are three published works by V K R V Rao on national income – An Essay on India’s National Income 1925-29 (1936); The National Income of British India (1940) and India’s National Income 1950-80 (1983). Though V K R V Rao has published on various aspects of economics, his work on India’s National Income is of special interest. This is because of a variety of reasons. Austin Robinson provides one such reason: ‘I myself remember Rao as the brilliant Cambridge undergraduate and research student of almost fifty years ago, who single-handed tackled the almost impossible task of estimating the Indian national income at a time when hardly a single ingredient was known and even guesses involved heroic despatch of countless questionnaires to every corner of India to establish, for example, the milk-yields of she-buffaloes or the average earnings of village barbers.’ An analysis of economic growth and change is possible by studying the National Accounts Statistics (NAS), as Rao has demonstrated in his 1983 book.

Despite the limitations of NAS in India, Rao is able to meaningfully explain the changing structure of the economy through the relative shares of agriculture, industry and services in the gross domestic product (GDP). In addition, he calculates the implicit price deflator so as to understand how much of GDP increase is on account of price rise. Also, implicit price deflators are constructed for the three major sectors to find out how each sector has performed vis-a-vis the others. Savings, capital formation and consumption are also dealt with in detail. V M Dandekar has hailed his 1983 book as ‘a model of scholarship and objectivity particularly coming from one who, during the period, was in the thick of making and implementing policies and programmes for economic development of the country.’

Thus, V K R V Rao was a model economist ‘ a practical man who was well aware of various theories and their limitations in applicability to India. And because he wanted to use economics for policy purposes, he was committed to extensive data collection and data analysis. Also, he was clear that, in practice, economics must interact with other social sciences, especially sociology and anthropology. This is evident from the name of the institute he founded in Bengalooru ‘ Institute for Social and Economic Change.

Paul Samuelson: The Father of 'Modern Economics' Dies

All those who have studied economics for the past 50 years or so have heard about Samuelson – Foundations of Economic Analysis, Samuelson-Stopler theorem, Factor-price equalisation theorem, revealed preference theory, Bergson-Samuelson social welfare functions, non-substitution theorem, linear programming in economics, etc. The first one is his 1947 book which dominates economics teaching even today, directly or indirectly. Samuelson transformed economics into some sort of science (pseudo-science, as some call it)-social physics. [For more on this, go here]

Robert Lucas on Samuelson:

‘Samuelson was the Julia Child of economics, somehow teaching you the basics and giving you the feeling of becoming an insider in a complex culture all at the same time. I loved the Foundations. Like so many others in my cohort, I internalized its view that if I couldn’t formulate a problem in economic theory mathematically, I didn’t know what I was doing. I came to the position that mathematical analysis is not one of many ways of doing economic theory: It is the only way. Economic theory is mathematical analysis. Everything else is just pictures and talk.’ [Marginal Revolution and here]

SCARY!

In his Foundations, he is supposed to have popularised the views of Keynes. In fact, what he popularised is the neo-classical synthesis (IS-LM curves, which were created by Hicks). Hence, what we learn in most macroeconomics texts is not what Keynes said. Post-Keynesian economics is more closer to what Keynes said.

Despite his ‘ideas of good economics’, one needs to appreciate the works he carried out in different areas in economics – macroeconomics, public finance, international trade, consumer theory, capital theory and general equilibrium, etc.

In his initial editions of the Foundations, one could find a few pages devoted to the 1960 capital theory debates. However, with passage of time, the debate was relegated to footnotes. Now, in mainstream textbooks, capital theory is entirely omitted. In fact, Samuelson admitted the problems neoclassical microeconomics and general equilibrium run into because of their notion of capital. [More here]

I end with two questions.
Is mathematics the only way of studying economics and analysing economies’ [We mostly use calculus and game theory. Should we employ other kinds of mathematics’]

How reliable are textbooks’ It makes learning easy, but probably, a bit too easy.
