THIS YEAR's ECONOMICS PRIZE AWARDED TO
DEVELOPING-COUNTRY RESEARCH
The Royal Swedish Academy of Sciences has decided to
award the 1979 Alfred Nobel Memorial Prize in Economic Sciences
to be shared by
Professor Theodore W. Schultz, University of
Chicago, USA,
and
Professor Sir Arthur Lewis, Princeton
University, USA,
for their pioneering research into economic development
research with particular consideration of the problems of
developing countries.
Schultz as Agricultural
Economist
Theodore W. Schultz was an agricultural economist to start with,
and in the thirtles and forties, presented a series of studies on
the crises in American agriculture, and then later took up
agricultural questions in various developing countries throughout
the world. His best known works from this period are
Agriculture in an Unstable Economy (1945), and
Production and Welfare of Agriculture (1949). His most
trail-blazing book was Transforming Traditional
Agriculture (1964). The main characteristic of Schultz's
studies in agricultural economics is that he does not treat
agricultural economy in isolation, but as an integral part of the
entire economy. Schultz's analytical interest has been focused on
the imbalance between relative poverty and underdevelopment in
agriculture compared with the higher productivity and the higher
income levels in industry and other urban economic activities -
and this applies both to industrialized countries like the United
States and to the many developing countries Schultz has
studied.
Schultz has received many of the impulses for his notable
analysis of the importance of human resources for economic and
social development from his studies of the productivity problems
in agriculture - in the United States as well as in the
developing world.
Schultz's analysis of the development potential of agriculture is
based on a disequilibrium approach. It is the gap between, on the
one hand, traditional production methods, and on the other, the
more effective methods now available which create the conditions
necessary for a dynamic development. Using this approach, Schultz
has, in various context, presented a detailed critique of the
developing countries' industrialization policies and their
neglect of agriculture. Schultz was the first to systematize the
analysis of how investments in education can affect productivity
in agriculture as well as in the economy as a whole. Well aware
of the limitations of the method, Schultz has, as a first
approximation, defined and measured the size of educational
capital as a sum of accumulated investments in education. A large
proportion of the costs of these education investments consist of
a loss of earnings from employment during study periods. These
are, therefore, a kind of alternative costs which can be seen
both in the private and in the national context.
Schultz on the Human Factor
Schultz and his students have shown that, for a long time, there
has been a considerably higher yield on "human capital" than on
physical capital in the American economy, and that this tension
has resulted in a much faster expansion of educational
investments than of other investments.
Schultz has always kept close to economic reality in his work,
both as an economic researcher, and as an adviser in various
capacities. He has shown a great wisdom as an economist with a
striking ability to define development factors which the
model-building economists are inclined to neglect.
But the broadness of his approach is also manifest in a number of
other factors and context which have to do with human resources
(the human factor). Schultz has done research on subjects
connected with health and disease as essential factors in
economic development in the Third World, as well as on population
issues in general. During his long career in research, he has
shown an outstanding skill in asking the relevant questions and
has opened up fruitful avenues of new research. Few economists
have done so much to inspire colleagues and students to do
worthwhile research.
Lewis on Poverty in the Developing Countries
Arthur Lewis is a leading figure and pioneer in developing
country research. His fundamental works from the middle of the
fifties - Economic Development with Unlimited Supplies of
Labour (1954), and Theory of Economic Growth (1955) -
have been followed by a series of other important works. The most
significant of these are his Wicksell Lectures of 1969
(Aspects of Tropical Trade, 1883-1965), and his latest
great book, Growth and Fluctuations, 1870-1913
(1978).
Lewis has tackled issues which are basic to the causes of poverty
among populations in the developing world and to the
unsatisfactory rate of economic development. His two famous
theoretical explanatory models, designed to describe and explain
the intrinsic problems of underdevelopment, have won great
acclaim and given rise to widespread scientific debate which has
resulted in a series of variations and additions to Lewis's
original premises.
The models have also been the subject of empirical testing which
has confirmed their realistic structure and usefulness.
The first model is based on the dual nature of a developing
economy. There is an agricultural sector functioning on
traditional lines and primarily based on self-support which
engages the labours of the greater part of the population, and a
modern market-oriented sector primarily engaged in industrial
production. The driving force in the economy stems from the
latter sector, which expands with the support of unlimited
supplies of labour by migration from the agricultural sector, and
workers accept the low wages corresponding to the living
standards and conventions in an underdeveloped agriculture. The
profits in the modern sector ("capitalist sector") create the
growing savings which finance the capital formation for
expansion.
Lewis's other basic model relates to the determination of the
terms of trade between developing and developed countries as
regards raw materials and tropical products, on the one hand, and
industrial products, on the other. Here, again, it is a question
of a simple model of a classical pattern. Two groups of countries
- south and north, poor and rich - each produce two kinds of
products, one of which they have in common, namely, food. The
other two products - in the model called "coffee" and "steel" -
are traded. Lewis shows how under specific conditions, the terms
of trade are determined by the relationship between the work
productivity in agriculture in the developing countries and in
the developed countries. According to this analysis model, the
relatively much lower productivity in agriculture in the
developing countries compared with the rich countries is the
determining factor in the current terms of trade between the two
groups of countries, i.e., the long-term development of
the terms of trade.
One interesting thing about Lewis's greatly simplified model
analysis is that it presents essential aspects of the reasons for
the poverty and development problems of the developing countries,
and another is that it can be integrated into a many-faceted
picture of the historical and statistical development patterns in
different countries of the Third World.
The experience he has gained from his numerous assignments as
economic adviser, and as the administrator of a large development
bank, has given him great insight into the way politicians and
dictators function. So he is on firm ground for tackling a
realistic analysis of the possibilities of economic policy. In
one of his earliest works from 1949 (The Principles of
Economic Planning), and even more so in Politics in West
Africa (1965), Lewis has discussed in detail the difficult
planning problems - from the standpoint of rational economics -
which arise when central planning ignores price signals from a
market system. In this context, Lewis has stressed the
distinction between "planning by direction" and "planning through
the market". This approach has always been a characteristic of
Lewis's research and is particularly evident in his latest large
work (Growth and Fluctuations ). He illustrates the
interaction between development in the then-industrialized
countries and developing countries during the long period of
1870-1913. Here, Lewis is very much the economic historian - with
an extremely scrupulous examination of statistical sources and an
impressive reprocessing of the material. In many essential
respects he sheds new light on both growth processes and short
and long economic cycles within the nucleus of industrialized
countries wnich influenced the development in a periphery of
developing countries.
Features in Common
Schultz's and Lewis's analysis of development problems have a
number of features in common. We see how well their contributions
complement one another. First, they have the same points of
departure. Economic development -- and this includes not only
economic growth -- is central to the research of both these
economists.
Schultz's work primarily concentrates on a number of strategic
questions related to conditions for efficiency in the employment
of production resources. Here, Schultz attaches crucial
importance to vocational skills, schooling, research and its
application. Schultz is a pioneer in research on "human capital",
a field which has been expanding rapidly since the end of the
fifties.
The efficiency and development of agriculture is also in Lewis's
opinion of vital importance for the situation and growth of the
developing countries. But Lewis has focused attention on the dual
nature of developing country economies, the tension between a
large, dominating and stationary agricultural sector, and a
dynamic industrial sector, which is sometimes in the nature of an
enclave. Even in another respect, the low productivity of
agriculture is, in Lewis's analysis, a causal factor for the
poverty of the developing countries and a restriction on growth,
namely, via effects on the terms of trade with developed
industrial countries.
Another feature Schultz and Lewis have in comon is the importance they attach to facts and empirical research. They both have extensive practical experience of development problems and apply this in their research. They are both extremely interested in the history of the course and form of development in various eras in different countries. Characteristic of them both is their interest in problems of economic policy. Both are deeply concerned about the need and poverty in the world and engaged in finding ways out of underdevelopment. In this context, both Schultz and Lewis are ready to draw daring conclusions which can lead to recommendations of changed economic policy. They are also very critical of the type of agricultural policy or other economic policy which have been pursued during various phases. Their widespread and profound experience of developing-country economic policies and underlying politicaI systems makes their presentations of developing-country problems vivid and sincere.
