DESCRIPTIVE ECONOMICS 101: I. THE STATE
Gilles Saint-Paul
In June 2000, a group of students whose names was not disclosed launched a petition complaining about the teaching of economics and the abuse of mathematics in that discipline. I originally thought it was a typically franco-french quarrel, another excuse not to talk about real problems; but it turns out that they have their followers abroad and that the international press is starting to pay attention to it. So I thought it would be useful to give some clarifications.
This attack is part of a general atmosphere of witch-hunting against economics and economists. The reason, I suspect, is that economics is not very friendly to the dominant ideology held by the intellectual establishment and by many sectors of the ruling left-wing coalition. Every month a new book is out complaining about the inhumanity of markets and globalization [1] or accusing economists of being immoral, incompetent, or dishonest [2]. One reads articles telling us that mathematics are the instrument of capitalist exploitation and that economists advocate the abolishment of democracy in order to impose the views of multinational corporations [3]. In the spring, we got a grande première: unions signed a manifesto protesting against the publication in a scientific journal of two articles which concluded that the minimum wage destroys jobs and that the welfare state reduces the unemployed's incentives to look for jobs. The manifesto included insulting insinuations against the quality of the research made by the authors, two leading French economists widely published in the top international journals.[4]
At about the same time, we got that other manifesto published in "Le Monde", which is both pro-government and very influential among French educated elites. A group of students from top undergraduate programmes in French universities criticized the teaching of economics. They have already achieved a lot: after having read their petition in the newspaper, the minister of education, Jack Lang, decided to launch a reform of the teaching of economics. At this stage, it is unclear what the outcome will be.
The three main complaints are (i) there is an excess
use of mathematical formalism for the sake of it; (ii) economics is cut
from the real world; and (iii) there should be more "pluralism", i.e. more
attention given to non-orthodox approaches and other disciplines. This
sounds reasonable and it is of course important to improve pedagogy. But
one does not solve pedagogical problems by sending manifestos to newspapers,
especially one that has been very supportive of the "Asterix"-style movement
against globalization, de-regulation, and more generally markets, that
has been burgeoning in France in the last two or three years. In
fact, it is just another battle in the political war against economics.
The ultimate goal is to impose the teaching of an "alternative" kind of
economics, which, in my view, would be as flawed and useless as Lyssenko's
biology.
When one looks in detail at their proposal
one realizes that the goal has little to do with pedagogy. These students
are
not complaining about the way economics is being taught to them. They are
complaining about the contents of their courses, i.e. about the discipline
itself. Let us examine these complaints
1. Mathematics.
Mathematics is the language of modern economic analysis.
Its relationship to the real world is the same as that of other languages:
things, concepts, and ideas are represented by symbols and the relationships
among these objects are made explicit by expressions that obey a given
set of syntactic rules. In the case of mathematics these rules are the
rules of logic.
Mathematics has imposed itself in main stream economics,
because it turns out to be the only way to check the logical consistency
of the analysis and to carry its predictions to the data, that are quantitative
in essence. The unfortunate result is that economics is no more fun to
learn than fluid mechanics. But that does not mean it should be changed,
even less that the students should decide what it should be. Up to now,
it has been possible to teach undergraduate economics in France in a fairly
mathematical way because teachers were used to have students fairly literate
in that area. In contrast, American teachers had to do contorsions in order
to avoid calling a derivative a derivative. As a result they taught the
same economics in a more entertaining and accessible fashion, but with
less rigour and precision. That French students now complain about mathematics
is the sign of the degradation of scientific culture in our country. In
fact, one of the complaints is that student enrollment is dropping in economics;
but one also sees it dropping even faster in science. This is all the more
ironical than virtually all our improvements in living standards over the
last century is due to science. Anyway, the obvious solution is to teach
the American way, by means of graphs and numerical examples. This does
not change the substance of what is being taught. But I would much prefer
a responsible and ambitious curriculum at the high school level, as well
as an explicit recognition that a given level in mathematics is necessary
in
order to become an economist.
2. The real world.
In the manifesto one reads: " Most of us have chosen to study economics so as to acquire a deep understanding of the economic phenomena with which the citizens of today are confronted. But the teaching that is offered, that is to say for the most part neoclassical theory or approaches derived from it, does not generally answer this expectation. Indeed, even when the theory legitimately detaches itself from contingencies in the first instance, it rarely carries out the necessary return to the facts. The empirical side (historical facts, functioning of institutions , study of the behaviors and strategies of the agents . . . ) is almost nonexistent. Furthermore, this gap in the teaching, this disregard for concrete realities, poses an enormous problem for those who would like to render themselves useful to economic and social actors."
The real world is complex and science is about decomposing it into simple phenomena in order to understand them and explain them. This cannot be done without a theory that tells us what we should expect to observe under what circumstances. The theory itself has to be understood and as long as it is not it is a waste of time to talk about the issues of the real world. To learn the theory one first has to learn its methods and then how to apply it to simple examples. These examples will inevitably be very stylized relative to real-world problems. This may sound disappointing but I do not see a better alternative. Similarly, an undergraduate course of fluid mechanics is pretty remote from the design of a nuclear plant, and it is hard to apply the law of gravitation to predict the outcome of a judo match. It is important to motivate the analysis with real-world examples; but, as we shall see below, the students want to go much further than that. In essence, they are questioning the basic scientific method of insulating and simplifying phenomena, and proposing some dubious criteria in order to select which part of modern economics should be taught.
The students are right to point out that the empirical side should not be neglected. It would be stupid to deny that. But, in modern economic analysis, empirics is not about historical facts or the functioning of institutions, but about formal statistical evidence on relationships derived from models, tested and estimated using the mathematical techniques of econometrics. And to understand such evidence and assess its validity, it is important to have studied econometrics and statistics. So we are back to mathematics! I would not go as far as saying that knowing history and institutions is useless; but it is useful to an economist only if he has learned to reason as an economist. This should be the central goal of our teaching.
I do agree that the theories should be validated
by evidence. If this is not done in the classroom, it may be because of
pedagogical problems but not because such evidence does not exist.
But I am not sure whether the students who signed the petition would be
more willing to accept the evidence than the theories. For example, are
they willing to accept the conclusions of the above mentioned INSEE-study,
against which the unions petitioned?
3. Pluralism.
Many of the students who
complained were first exposed to a traditional French style of doing economics,
based on commenting ancient texts and describing institutions. The scientific
approach has been a shock to them.
This traditional style is
still epitomized by the French agregation contest, which one has
to take to become a university professor. This contest puts considerable
emphasis on institutions and history of economic thought, not so much on
modern economic analysis, and very little on being a good researcher with
a good publication record in international journals. It traditionally includes
a silly "rite de passage", whereby a candidate has to give a lecture on
any topic, of which he or she is informed 24 hours in advance. Most of
the work is to gather a team of people who are spread across various university
libraries and have to write, as quickly as they can, reviews of the few
books adressing the topic. Such criteria are biased toward selecting conservative
people unlikely to be up-to-date and even less to move the frontiers of
knowledge. As a result, French economists of international stature have
traditionally been confined to the administration, the grandes ecoles,
or the CNRS, but have been absent from the university. Needless to say,
many of them are abroad. A recent study ranked French economists on the
basis of citations in international journals [5]. Out
of the top ten, six are abroad. Of the remaining four, only one is a university
professor, and he is a Harvard Ph.D. who personifies the kind of economics
that the students complain about. By chance, things were progressively
changing under the impulse of a few dynamic research centers within some
universities, and French university economists were at last starting to
publish in international journals. It is this painful path to excellence
which is being jeopardized.
But, will you ask, if French university professors are recruited on such criteria, how come that they teach mathematical economics? The answer is that most of them don't. In fact, most economics in France is taught in the fashion that these students petitioners advocate. The students' petition was followed by a petition by 200 professors, i.e. a substantial fraction of the profession, who, unless they are schizophrenic, should not teach the 'dominant' theories. The student's petition originated from one of the undergraduate programmes which insists on the quantitative methods of modern economic analysis; but such programmes are not the majority and the students elected it because it was a good programme associated with a centre of excellence, rather than many others that insist far less on formalism and are more "pluridisciplinary". In other words the students are facing their own contradictions. If you prefer Pepsi-Cola to Coca-Cola, you don't have to drink Coca Cola, nor to demonstrate against it.
This sheds a new light on the call for "pluralism". The manifestos complain about a so-called "dominant", neo-classical way of doing economics. They write:
"Out of all the approaches to economic questions that exist, generally
only one is presented to us. This approach is suppose to explain
everything by means of a purely axiomatic process, as if this were THE
economic truth. We do not accept this dogmatism. We want a pluralism of
approaches, adapted to the complexity of the objects and to the uncertainty
surrounding most of the big questions in economics (unemployment, inequalities,
the place of financial markets, the advantages
and disadvantages
of free-trade, globalization, economic development, etc."
This 'approach'--which I think has imposed itself precisely because it is not dogmatic-- is indeed dominant in most countries but not in the French university system, and, as I said, there is no scarcity of curricula that correspond to what these students want, starting with the famous "Science-Po" school which trains most top civil servants and many journalists and private sector executives. So by pluralism they don't mean having more freedom to choose what to study, but two things.
First, diluting the messages of contemporary economic analysis, which insists on incentives and individual selfishness, by mixing them with contradictory messages from other disciplines and approaches. The result will be to prevent students from critically analyzing economic issues and will instead lead them to superpose on it an unconclusive literary discourse. In light of the above mentioned union petition, the objective is to reduce the influence of economics because its predictions are often at variance with dominant views about economic policy in French circles. When the level of discourse is as low as "pollution permits = permits to kill", or "don't touch pensions", economics or even common sense is unwelcome. So called "neo-classical" economics has in fact a clear message on many of the real-world issues mentioned. Like: globalization benefits consumers, the common agricultural policy is inefficient, financial markets helps people and firms to hedge against risk, unemployment is higher when unions are more powerful and unemployment spells longer under strict employment protection legislation, economic development is fostered by well enforced property rights on assets, etc. Furthermore, it has the power of qualifying these messages by examining the effect of different assumptions regarding technology, tastes, information, and institutions.
Second, more "pluralism" means more jobs for "alternative" approaches: institutionalists, neo-marxists, and so on, and less jobs for "orthodox" economists. I will refrain from making value judgements about the quality of the research produced by each category. But the "orthodox" submit their research to international journals with a stringent review process by acknowledged specialists, while the "alternatives" typically publish in French journals that reject far fewer papers. If they prevail, more good economists will have to leave the country, and French intellectual life will be even more entrenched and provincial, an inevitable recipe for mediocrity. It is a bit as if the French soccer federation decided to change the rules of the game, just for France. Would we be World Champions?
4. What they propose:
Finally, in order to make their point most clearly,
the students have proposed a curriculum in three parts which would restore
the teaching of economics in France as it was in 1945. [This curriculum
is described in Box 1 below] There is a descriptive block which depicts
French and International economic institutions, starting of course with
its majesty the State, and concludes by describing the economy. It has
no room for thinking and analysis, and is not transferable: the organigram
of a given institution is a piece of knowledge that can only be applied
to that particular institution, not to other problems. In contrast, one
should insist on teaching methods of analysis that can apply to variety
of issues, including issues that have not arised yet.
The second block is the unavoidable History of economic
thought part, which familiarizes people with economics as it was in the
past. This is a tribute to the literary tradition in the discipline,
but a denial that progress has been made and that the old ideas that have
not proven false nor inconsistent are now embodied in the analysis in a
way much more coherent, precise and explicit about underlying assumptions.
Modern economics is therefore confined to the third
block, which, according to the students, should be taught in a case study
style on the basis of contemporary issues. A striking feature is that there
is no reference to any advance that was made after say 1960. However, the
issues proposed are interesting and relevant: privatisation of health insurance,
the effect of tradable pollution permits, etc. But, to be able to address
these problems, you need to be very comfortable with economic analysis.
And this takes a lot of work. I fail to see how the reading of Marx
or knowledge of the organigram of a French ministry can be of any help
to answer such questions.
What the students are proposing, far from
a reform, is in fact a regression to a situation where economics is not
an autonomous discipline but a literary discourse at the cross roads between
humanities and law. The next step would be to stop teaching it altogether
and to lump it into some "general contemporary culture" curriculum. In
fact, some of their supporters are quite close to such a conclusion.
For example, one of them, in the newspaper Le Monde, writes: "most of neoclassical
microeconomics should be taught in the context of history of economic thought,
along with the marxist theory of work-value or other theories of value,
and should be excluded from freshmen and sophomore years "[6].
Of course, it is pure nonsense to lump the centerpiece of modern economics
with obsolete theories more than a century old. And the author, who does
not know what to teach instead, advocates that "alternative manuals" should
be written. Why hasn't he done it already?
These attacks constitute the best proof of the relevance and importance of economics. You don't make ennemies if you are useless.
BOX 1: The students' proposed curriculum.
First Group: « Descriptive economics : history of economic and social phenomena , actors and institutions » | 1. History of economic and social
phenomena (including the history of economic and social policies).
2. Actors, organizations, institutions. -The State (public administrations, public law, public finance) -Firms (accounting methods for private firms, commercial law, financial analysis…). *The financial and the banking system (The banks and the Central Bank, money and finance). *Trade Unions (collective bargaining, labor law). *Associations (diversity, the social economy). *International economic institutions (international economic relations, the international monetary and financial system, public law, international law…). 3. Descriptive economics (active population, structure of the productive system, household's budgets), national accounting systems, economic geography (studying the areas of economic integration, problems of development..). |
Second Group : « Theories and issues » |
1. History of economic theories (The Classics, Marx and
Marxism, Marginalism, Keynes and Keynesianism, the Austrians, the
Neoclassicalists, the Institutionalists).
2. Political and moral philosophy (thinking about the concepts of justice, equality, distribution, efficiency,…). An important part of this course will have to be assigned to the examination of case studies (such as « can health care be left to the free interplay of market forces ?, « up to what point should borders be opened ? », should genes be treated as commodities ? |
Third Group : « Applied economics and quantitative methods »
|
-Taxation (should the petrol tax be lowered ? should the income tax
system be reformed ?).
-Administered prices and the pricing of public utilities’ services (Electricite de France, the national railways -SNCF, prices, the prices of pharmaceuticals,…) -Pollution (the market for the rights to pollute, ecotax,…). -The regulation of financial flows (Tobin Tax, prudential regulation). -The social minima (the unemployment trap, disincentives..) -Economic forecasting (contribution and limits of modelling). -Competition (regulation of monopolies, anti trust policies,…). -Insurance (information asymmetries, social insurances such as social security). -Auctions. In the same vein we include in this group the topic economic and social policies. This inclusion will allow the study of the IS-LM and Mundell Fleming models etc as tools addressing specific questions (such as the coordination of budgetary policies in the Euro zone , exchange rate policies…). |
Options (such as Law, sociology, psychology, history, microeconomics,
game theory) can also be pursued during the course of studies in order
to facilitate interdisciplinary openness.
