On Economics and Ethics

Ever since political economy became economics, the role of ethics has continually diminished in the learning of economics. This is because economists want(ed) their discipline to be scientific. To serve this purpose, economics has been divided into normative economic and positive economics. Normative economics deals with questions such as ‘what ought to be the price configuration’ whereas positive economics deals with questions such as ‘what is the configuration of process’. In other words, there is no room for debate in positive economics; at least, that is the impression one gets from reading the mainstream textbooks. Amartya Sen tried to remedy this situation by strengthening the area of welfare economics; however, methodologically, it still adopts a ‘positive economics’ framework. In any case, this development motivated economists to ask humane and ethical questions. This post raises some issues concerning the role of ethics in economics.

Adam Smith, the father of economics, did not only write Wealth of Nations; being a moral philosopher and an acute observer of society also published a book titled Theory of Moral Sentiments. This book talks of sympathy, passion, ambition, justice, duty, utility, custom, virtue, self-command, etc. Often, proponents who favour utility maximization cite Adam Smith as the first one to do so effectively. As much as one glance at the table of contents of Theory of Moral Sentiments will say otherwise.

This brings us to the following pertinent, yet very difficult questions. What is the objective of economic policies or economic engineering’ What role does economic theory play in policy making’ Does economic theory provide tools, methods and concepts that aid policy formulation’ The final objectives of economic policy invariably happen to be poverty elimination, reduction of unemployment, inflation control and provision of a good standard of living to all the inhabitants. Hence, various kinds of policies are undertaken to achieve these broad objectives. Very often, economic theory aids such policy making exercise in a significant manner. Now, we come to a very startling observation. Economic theory (which is positive in nature) has no room for conflicts, ethics or values. Instead, the major criterion which dominates most economic theorization is that of economic efficiency ‘ free markets achieve efficiency. So what’ The goals of economic policies are not to make markets efficient or free; instead, it is to provide the inhabitants with a good standard of living. In India, how can markets take care of the diversity in caste, language, region, income, etc’ Economists must do away with their arrogance and admit that policy making is a serious and complex matter, which cannot be solely guided by macroeconomic models of the general equilibrium variety!

For instance, the variables which the government tries to engineer affect people in different and often opposite ways. Alterations in interest rates affect lenders and borrowers differently. Also, movements in exchange rates affect exporters and importers in exactly opposite ways. More importantly, changes in prices of goods and services affect those who cannot afford it very adversely. Given such differential effects of policy variables, economics must incorporate ethical discussions into its fold. Perhaps, a reading of Theory of Moral Sentiments will be of great help!

 

For ‘Social’ Economists

Over the past years, I have come across many students of economics who complain about the irrelevance of economics to understand practical issues. Among them, some go on to choose sociology, which is considered to be more practical and realistic. This post is for those who think that the dominant practice of economics is not done the right way. It is certainly possible to be a ‘social’ economist. In fact, this post is about ‘social’ economists and not about social economics, a distinct field in economics, which comprises economists who think ethics, values, philosophy, culture, etc are important.

Social economics/socio-economics/new social economics are emerging fields within economics whose central premise is that one cannot study an economy meaningfully without paying attention to social institutions, culture, beliefs, etc. It is disturbing to know that the practitioners of social economics, socio-economics and new social economics distinguish their work among themselves. This trend is largely because of the urge to be ‘pioneers’ in ’emerging’ areas in economics. The following extracts from The Elgar Companion to Social Economics shows this clash of identity:

‘The association that promotes socio-economics, the Society for’ the Advancement of Socio-economics (SASE) advertises itself rightly as’ an interdisciplinary organization. In recent years, socio-economists have’ increasingly used insights from biology, in addition to psychology and sociology.’

‘The association that promotes social economics, the’ Association for Social Economics (ASE), presents itself as a pluralistic’ organization that emphasizes the role of social values and social relationships in economics. Social economists have a variety of additional orientations, including institutionalism, Marxism, feminism, post-Keynesian,’ Kantianism, solidarism, neo-Schumpeterian, environmentalism and’ cooperativism. ‘

‘There is also a quite recent literature termed the ‘new social economics‘,’ which begins with market relationships, and then seeks to add ‘non-economic’ social content to their analysis. That is, rather than embed the’ economy in social relationships, these more recent contributions seek to’ embed social relationships in the market. ‘

In any case, these emergent fields indicate a dissatisfaction with the dominant economics profession. However, in their haste to carve out a separate field, the essentials are often lost. The adjective social prefixed to economics indicates the existence of an economy which cannot be clearly demarcated from the society in any clear fashion. Moreover, this usage also emphasises the role of how society is organised. The following are some questions pertaining to the economic aspects: Are the people motivated by reason’ To what extent does profits motivate entrepreneurs’ On what basis are people employed ‘ caste, gender, religion, academic qualification, political connections, bribes, region’ Can we visualise distinct social classes in the economy based on their ownership of land’ What are the sort of interactions which take place between agricultural, manufacturing and service sectors’ How is finance organised in the country’ How important are informal sources of finance’ Does labour laws apply to all sorts of employment’ How does the government intervene in domestic production and consumption of commodities are services’ What sorts of price and quantity controls exist’ These are some of the questions which aid in understanding how the economic aspects of a society are organised.

Today, economists are asked for their opinion/advice on matters pertaining to financial crises, foreign exchange constraints, poverty, unemployment, inflation, rural development, etc. Only an economist who is reasonably aware of how the society is actually organised will be able to devise strategies and chart plans which can effectively tackle these economic issues. A ‘social’ economist is one who understands the complexity of social studies in general and of economics in particular. In addition, she will always resist the temptation to think in atomistic terms and will resist universal solutions. She will also be aware of the significance of non-market transactions.

Even if the dominant form of economics teaching and research is asocial, the academic enterprise of economics does give space to alternative approaches. However, one must be careful because some of these approaches appear ‘social’ but are in fact static and atomistic. A reading of Adam Smith, the father of economics, easily points to the role and significance of social values and institutions. It is for this reason that we need to return to classical economics, where, as one of the earlier posts argued, economics is’ the study of commodities; but their economic analysis can easily incorporate social values and institutions as well.

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.

Knut Wicksell: Some Aspects of his Work

This post is different from the others because it deals with the contributions of a single economist. Knut Wicksell was a Swedish economist who made significant contributions to capital theory, monetary economics and fiscal policy. Despite being grouped under the neoclassical or the Austrian school because of his affinities to ‘marginal’ analyst, Wicksell was a socialist and a radical. He advocated policies which involved the government in a big way. And owing to his varied interests in poetry, mathematics, feminism, mathematics, politics, etc he became a Professor of Economics and Fiscal Law at Lund University only when he was fifty. A few of his well known students are Erik Lindahl, Gunnar Myrdal and Bertil Ohlin. They are considered to be part of Stockholm or Swedish school of economic thought.

In the passages below, only a few of his contributions will be elaborated. He has also made lasting contributions to the theory of interest, revitalised quantity theory of money, introduced mechanisms linking the real and monetary sector, etc.

Wicksell demonstrated that problems could arise if capital is treated just like other ‘factors of production’ ‘ land and labour. Cambridge capital controversies dealt with many of these problems. ‘Knut Wicksell (1851’1926) himself casts doubt on the specification of the value of capital, along with the physical quantities of labour and land, as part of the data of the system. ‘Capital’ is but a set of heterogeneous capital goods. Therefore, unlike labour and land, which ‘are measured each in terms of its own technical unit . . . capital . . . is reckoned . . . as a sum of exchange value’ (Wicksell, 1901, 1934, p. 49). But capital goods are themselves produced commodities and, as such, their ‘costs of production include capital and interest’; thus, ‘to derive the value of capital goods from their own cost of production or reproduction’ would imply ‘arguing in a circle’ (ibid., p. 149).’ [Segura and Braun 2004]

Like other contemporaries of his, Wicksell did not write about unemployment. This was because the existence of unemployment was considered to be a paradox, an anomaly for neoclassical economists. As they could not comprehend why resources (here, labour) would be left idle! The central problem in (neoclassical) economics was not to provide or create uses for factors, but only to allocate the factors among various uses. As Bo Sandelin, editor of Wicksell’s papers and the author of A History of Swedish Economic Thought writes in the introduction that ‘the fundamental question in economics was how to manage an economy with scarce resources.’ Strange indeed!

Wicksell was a strong proponent of the marginal productivity theory of distribution. A corollary of this theory is the the sum of all the marginal products of the factors should be equal to the total product, known as the product exhaustion theorem. However Wicksell demonstrated that the operation of this theory depends on the returns to the scale. That is, only under constant returns to scale will the marginal products exactly add up to the total product. And that for both decreasing returns and increasing returns, the product will not be completely exhausted.

The Swedish school made another important contribution to economic theory. They introduced the categories of ex ante and ex post. These categories, we know are used widely today and were the result of the School’s dissatisfaction with the equilibrium analysis. Apart from these ways of thinking, Myrdal has provided us with the concept of circular and cumulative causation as well. These categories provide us with alternative modes of conceptualising or thinking about economic problems.

Relying solely on textbooks reduces our extent of reach. We often fail to come across interesting and heterodox economists. But, history of economic thought provides us with ample personalities to look into. Wicksell is one among them. Also, some of their categories provide us with alternatives, which remain unfinished. For instance, after going through some of the secondary and primary works on/by Wicksell, he appears exceedingly interesting and aware of the implications of certain simplifying assumptions. He pointed out the ‘necessity’ of the constant returns to scale assumption, which economics faithfully aligned with for a considerable period. This was challenged within the mainstream only with the entry of the endogenous growth theories, which emphasised increasing returns.
