On Neo-classical economics

This post is the first in the series- On Neoclassical Economics. This series attempts to look at the basic concepts of Neoclassicalism or Marginalism. The concepts that this series will cover are that of man being rational, measurement of utility, equilibrium from demand and supply, Micro and Macro economics and notion of perfect competition.

Remind yourself that what we (mostly) see in textbooks is Neoclassical economics (In India). Is there another approach to Economics which these textbooks fail to talk about’ The answer is yes. It is known as ‘Classical Political Economy’.

Classical Political Economy

The concern of the classical economists from Adam Smith to David Ricardo was the laws governing the emerging capitalist economy, characterized by wage labour, an increasingly sophisticated division of labour, the coordination of economic activities via a system of interdependent markets in which transactions are mediated through money, and rapid technical, organizational and institutional change. In short, they were concerned with an economic system in motion. [Kurz and Salvadori 1998]

This approach does not break economics into monetary, fiscal, international trade, microeconomics, macroeconomics etc. Nowadays, economics has got lot many divisions and specialties, that I feel the essence is getting compromised. [Thomas 2006] Classical Political Economy does not make such compartments like the ‘mainstream economics’ and is also dynamic in nature.

Neoclassical economics began as a project to fashion an economic model in the image of Newtonian mechanics, one in which economic agents could be treated as if they were particles obeying mechanical laws, and all of whose behaviour could, in principle, be described simultaneously by a solvable system of equations.

This post delves into the origin and the importance utility enjoys in Microeconomics aka ‘the pet of Neoclassicalists‘.

Economists are subject to many vices, and one of them has been to talk about ‘utility’, which is a quantitative conception that there is no known way of measuring. [Robinson 1979] Still, hours and hours are dedicated to the task of measuring Utility and ‘Marginal’ Utility in colleges and universities. It forms the basis of Microeconomics and also helps in bringing more mathematics into the realm of economics.

Bernard Guerrien writes in Issue 12 of the Post-Autistic Economics Review that ‘The French students’ movement against autism in economics started with a revolt against the disproportionate importance of microeconomics in economics teaching. The students complained that nobody had really proved to them that microeconomics was of any use; what is the interest of going through ‘micro1’, ‘micro2’, ‘micro3’, etc., using lots of mathematics to speak of fictitious households, fictitious enterprises and fictitious markets”

Can economic policies be made based on such ‘fictitious’ measurements’ Is economics a policy science or an intellectual game’ One becomes a skeptic when wondering about why ‘Microeconomics’ has come to dominate economics learning. Is it to make economics more mathematical’

A digression: Economy

The concept of the ‘economy’ is of utmost importance in this regard. Does the ‘economy’ occupy a separate existence from that of the community and the state’ Very often, the headlines in the media say so, but it is not so. And economics is not tantamount to money.

According to C. T. Kurien, Economy is a structure of relationships among a group of people, in terms of the manner in which they exercise control over resources, use resources and labour in the production of goods, and define and settle the claims of the members over what is produced, emphasising that while the economy is concerned with goods and services, it should be recognised essentially as a set of social relationships.

The economy consists of two realms, namely the community and the market. Community refers to real, on-the-ground associations and to imagined solidarities that people experience. [Gudeman 2001] Gudeman goes on to say that ‘Neoclassical economics focuses on one value domain, the market, which is modified as a separate sphere making up the whole of economy in which all goods are priced and available for exchange.’

On Utilitarianism

Bentham played a crucial role in the development of ‘utility measurement’. He proposed the ‘felicific calculus’, namely the quantitative evaluation and the algebraic summation of pleasures and pains stemming as consequences from any given course of action. ‘Good’ is whatever gives as its result an algebraically positive felicific magnitude, and hence increases the ‘amount of happiness’ within human societies; ‘bad’ is whatever gives as its result a negative quantity, and as a consequence decreases the amount of social happiness. [Roncaglia 1999]

But, Mill in his Utilitarianism (1987) criticizes this notion of measurement of utility by stating that ‘Utility is an uncertain standard, which every different person interprets differently, and even ‘in the mind of one and the same individual, justice is not some one rule, principle, or maxim, but many.’

If there is an intellectual field where the utilitarian attitude-namely, looking at the consequences of human actions-dominates, to the point of being identified with the scientific attitude tout court, this is economics‘ [Roncaglia 1999](Italics added)

Utility, when taught to students, appears very logical and thus is easily comprehended and imbibed. Of course, no individual would do any activity if it didn’t give him or her pleasure or rather, ‘utility’. As a philosophical concept, it does make sense. But when it is introduced into the realm of economics, it fails miserably. The demand function which is built on utility along with the supply is what determines the equilibrium price and quantity in neoclassical economics. But if one stops to think and to try and relate it to the real world, one would fail. Think of how prices are determined; and are prices based on demand and supply functions’

Conclusions

What has neoclassical theory taught us’ That individuals do what they do because they get ‘utility’ out of it’ And that this helps in calculating the demand of an economy which further helps in the determination of prices’ Does it tell us anything about the working of the economy’

India: Public and Private spending on Health

The following three maps will show us that, though the’spending in health by the private sector is comparatively much larger than the public sector, yet HIV prevalence is very high in India.

This shows the dire need for targeted public’investment in health care. This is because private sector’investment does not extend to the rural areas and regions with low purchasing power. [Investment is a part of spending]

Public Health Spending

Territory size shows the proportion of worldwide spending on public health services that is spent there. This spending is measured in purchasing power parity.

HIV Prevalence

 

Territory size shows the proportion of all people aged 15-49 with HIV (Human Immunodeficiency Virus) worldwide, living there.

Private Health Spending

Territory size shows the proportion of worldwide private spending on health services that is spent there. This spending is measured in purchasing power parity.

On Perfect Information

Four persons A, B, C and D have to share Rs 4 among themselves in units of one rupee. First A proposes a distribution and all of them, including A vote on it. If at least 50% of those voting agree with A, the proposal is accepted. If not, A loses her voting rights and B gets to propose a distribution and all except A vote on it. Once again B’s proposal is accepted if at least 50% of those eligible to vote agree on it. If not, B also loses her voting rights and C gets to propose and so on to D. Assume that each person prefers more money to less and will always vote against a distribution in which she gets zero. What distribution would A propose’

This is a sequential game. It is one in which players make decisions (or select a strategy) following a certain predefined order, and in which at least some players can observe the moves of players who preceded them. If no players observe the moves of previous players, then the game is simultaneous. [Game Theory.net]

This is also one of perfect information. If every player observes the moves of every other player who has gone before her, the game is one of perfect information. [Game Theory.net]

In the sequential game with perfect information, A will propose 3 for himself and 1 to D. This will be accepted by both A and D. D will accept anything more than 0; the reason being that, if all the proposals are rejected and the 4 rupees come in Cs hand, he will take all 4 for himself and since he will will vote for himself, the proposal will get accepted.

In such a game, the one makes the move first will have undue advantage.

On Perfect Competition

This market environment is extensively studied in Economics and is considered as a “Perfect” environment especially on the basis of efficiency.

This write up explains the concept of perfect competition succinctly.

Is such an environment favourable for all ‘ Competitive markets emphasise the importance of having perfect information as a pre requisite for a competitive equilibrium; one which is also Pareto Efficient.

The consumption decisions taken are sequential in nature. The consumer decides to purchase the commodity or service keeping in mind the price; which has been fixed earlier keeping in mind the consumers preferences. The outcome will always favour the producer (In a perfectly competitive market) as he makes the decision of pricing first.

On Pareto Efficiency

An outcome of a game is Pareto efficient if there is no other outcome that makes every player at least as well off and at least one player strictly better off. That is, a Pareto Optimal outcome cannot be improved upon without hurting at least one player. [Game Theory.net]

Conclusion

If the objective in an economy is Pareto Efficiency, then it can be achieved by a competitive market. But, it does not take into consideration equity in distribution. For example, in the game mentioned above, an allocation which leaves A with all the 4 rupees is Pareto Efficient, because in order to make someone better off, A has to be made worse off.

In India, the objective is to reduce Poverty and make growth more wide spread rather than growth being segregated in nature.

The idea that we cannot achieve the ideal state of perfectly competitive market equilibrium might seem pessimistic. Some economists insist upon holding the capitalist system to a standard of competitive equilibrium. Failure to meet this standard constitutes a “market failure” that warrants government intervention.[MacKenzie 2006]

So, is a market environment with perfect information desirable’

On History of Economic Thought

Economics has been getting more mathematical with the passage of time. Students opt for maximum papers in mathematics so that they can remain competitive academically at the international level.

Stark inequalities are present in the syllabi within India. In the South, the undergraduate degree does not lay much of emphasis on mathematics in comparison to the North, where the emphasis on mathematics is very high. One reason is that, in the South a degree is Economics is considered as one of the Arts subject, while in the North it is transitioning into a Science subject.

This affects the discipline of Economics. In certain areas of Economics, it requires analysis which needs the use of mathematics; but is it that Economics requires mathematics in all areas’ But again, this depends on if one views Economics as a Positive or a Normative discipline.

Axel Leijonhufvud writes in his paper The Uses of the Past– The history of economic thought used to be part of the graduate studies in economics. Sixty or seventy years ago, it was common of famous teachers like Lionel Robbins or Jacob Viner to approach economic theory by way of its development. Today, of course, this is seen as an archaic way of going about it and it has become quite uncommon. The history of thought is still a tolerated subject-in at least a few places- but not one to be studied to improve ones understanding of today’s economics. [Via: New Economist]

For those who want to have a deeper understanding of the discipline of Economics, learning the history of economic thought will prove to be highly beneficial. It will help in understanding how the dominant theories came by and how the theories get refuted. When history of economic thought is aided with economic history, it will provide a clearer understanding of economics to the student.
