I tremendously enjoyed reading this book. Geoffrey Hodgson (Research Professor
in Business Studies at the University of Hertfordshire) tells a fascinating
tale of how economics and social science more generally became abstract and
formalistic sciences with little interest in historical and institutional
particularities and he develops the beginnings of an account of how the
perceived shortcomings may be ameliorated. Throughout, Hodgson’s aim is twofold
— which is apparent already in the title. How Economics Forgot History
refers to a historical narrative about how economics has been transformed from
a science of concrete historical and institutional fact to a science of
universal and abstract truths about human choice. The Problem of Historical
Specificity, by contrast, is a methodological concern. Its question is the
range of applicability of economic generalizations, or how “universal” the laws
of economics really are.
The historical narrative traces the development of economics (and, in part, of
sociology) from Karl Marx to contemporary neoclassical theory along the stages
of the older German Historical School and their British counterpart, Alfred
Marshall and his debate with British historicists, Carl Menger and the
Methodenstreit, the younger Historical School of Gustav Schmoller,
Werner Sombart and Max Weber, institutionalism in America, Talcott Parsons’s
sociology, Lionel Robbins’s methodological ideas and Keynes’s General
Theory. But the history is a very focused one. It highlights only events,
ideas and theories relevant to Hodgson’s methodological concern: the problem of
historical specificity.
So what exactly is that problem? Hodgson does not quite define it but rather
tells us that “[i]t first acknowledges that there are different types of
socio-economic system, in historical time and geographic space. The problem of
historical specificity addresses the limits of explanatory unification in
social science: substantially different socio-economic phenomena may require
theories that are in some respects different” (p. 23).
In other words, the concern is whether theories in the social sciences can be
general theories of human nature (or indeed even encompassing non-human animals
and inanimate complex systems) or whether they have to pay attention to the
details of concrete circumstances such as history, geography, culture,
institutional set up and so on. In Hodgson’s view, a satisfactory economic
methodology must imply an answer to that question.
Hodgson’s own methodology attempts to strike a balance between a strict
empiricism and a strict rationalism. He criticizes empiricism for its failure
to realize the need for a prior conceptual framework and something like a
principle of the uniformity of nature in order to make sense of observational
data. On the other hand, methodologists who incline toward what we might call
economic rationalism (my term, not Hodgson’s) fail to realize that economic
laws are valid often only in specific circumstances or for specific
socio-economic systems because they base their theories on a priori
considerations about human nature. What we need instead is a methodology that
(against empiricism) uses some ahistorical (i.e. truly universal) and
transhistorical (i.e. pertaining to more than one socio-economic system)
concepts and principles and combines this (against rationalism) with a quest
for concepts and principles whose domain of applicability differs from case to
case and may comprise only a single socio-economic system.
Hodgson’s narrative, as a consequence, is a search for answers to the issue of
which concepts and principles can be regarded as a- or transhistorical and
which are more closely tied to a particular system. Marx, for example, regarded
history as a sequence of stages that are constituted by their characteristic
production relations. He thus noted the problem but also failed to solve it in
a satisfactory way: “The problem is not that Marx uses transhistorical or
ahistorical categories but that he gave no methodological guidance on their
importance, or on the means of choosing or establishing them” (p. 51). The
older Historical School made the mistake of laying too much stress on fact
gathering at the expense of general concepts and principles while Carl Menger
neglected specific fact. Schmoller got many things right but even he “did not
show in detail how [institutional and cultural] factors affected the outcomes.
For all his concern with causal explanation, Schmoller did not paint an
adequate picture of how an explanatory theory could be built, or of how its
core concepts could be right” (p. 115). Similarly Veblen’s historical and
institutional framework is commended but “[a]lthough he developed some key
ideas that would have helped to open a richer theoretical approach, he failed
to deploy them in the service of such a sustained project” (p. 150). Finally,
Talcott Parsons and Lionel Robbins are presented as the gravediggers of the
interest in the problem of historical specificity and creators of the
ahistorical vision of social science that formed the consensus of much of the
twentieth century.
In the methodological part of the book, Hodgson attempts to develop a response
to the challenge that Marx, historicism and institutionalism left with us, and
which has been ignored by more recent work in social science. His response
consists essentially in relegating concepts and principles to the right level
of abstraction, five of which he distinguishes (Table 21.2, pp. 326-27).
Certain concepts and principles pertain to all “open, evolving and
complex systems.” At this level, theorizing is informed by evolutionary theory,
general systems theory and complexity theory. At the second level, concerning
all human societies, human instincts and psychology as well as general
anthropological principles govern theorizing. The usual laws of supply and
demand come into play at the third level concerning only “civilized and complex
human societies” while the fourth and fifth levels differentiate between kinds
of socio-economic system. This very general framework can be applied to
concrete cases using the various principles that Hodgson introduces, such as
the Principle of Dominance (concerning what kind of institution
dominates a specific system), the Principle of Prominence (concerning
whether a certain institution is very common in a system) and the
Principle of Impurity, which says that any system will host more institutions
than the dominant one (e.g. though market relations are dominant in capitalist
systems, non-market institutions such as the family persist).
Hodgson’s view of what is the fundamental methodological problem in social
science and his response are highly original and insightful. But in my view, he
himself falls prey to a number of methodological flaws and omissions. To begin
with, I think Hodgson is right when he says that a pure empiricism is an
incoherent position. We do not learn much from sense data alone. But this does
not imply that there are any concepts or principles that are a priori in
the strict sense, i.e. prior to all experience. A tenable form of empiricism
can hold that while any particular inquiry may require some sort of background
knowledge, this background knowledge is itself neither infallible nor innate.
While we surely need a conceptual framework in order to make sense of
observations, the conceptual framework itself can, at a different stage of the
inquiry, be subject to revision in the light of new experience. Similarly,
while we need some kind of inductive principle to learn from experience, the
exact formulation of that principle can itself be extracted from what has been
successful in the past.
Therefore, I think that Hodgson concedes too much to the rationalist (or
theorist). This concession is relevant to his own theoretical framework. Much
of it is informed by very general theory-schemes such as general systems
theory, complexity theory and, in particular, evolutionary theory. There is of
course nothing wrong with borrowing analogies from these schemas. But Hodgson
seems to treat these as givens rather than hypotheses. Maybe the analogue of
natural selection is an important causal factor in economic phenomena, too. But
maybe it is not. Hodgson’s methodology has no built-in mechanism which weeds
out false hypotheses of this kind.
A related but different criticism is that Hodgson is a realist (or
essentialist) about concepts. Concepts, according to him, “carve reality at its
joints” (p. 315) and represent “what is essential to, and enduring in, an
entity — ignoring the accidental and superficial” (p. 287). On the basis of
this theory, for instance, Gary Becker’s neoclassical analysis of family
relations is criticized. Since it is in the nature of market phenomena
(the kind of phenomena to which neoclassical analysis was tailored) that
property rights are exchanged, and no such exchange takes place in the family,
Becker’s analysis must fail. But whereas I grant that Becker’s theory is
untenable, this is not because he gets the nature of market phenomena or the
nature of the family wrong. Indeed, it is possible that certain cases of
marriage and certain cases of prostitution are sufficiently alike that for
certain kinds of inquiry we may treat them as the same. We use concepts to
classify phenomena. It is now more or less generally accepted that there is no
one unique way of doing so. Each classification is more or less suitable for
the particular inquiry at hand. Thus, concepts have no real essence.
Finally, we may ask how useful Hodgson’s own response to the problem of
historical specificity is. Imagine, I am a monetary economist and concerned
with the quantity theory of money. Reading the present book, I learn from him
that institutions and historical and geographical circumstances matter —
sometimes at least. So I set out to test the theory for US post-war data. Are
my findings projectable to other countries or times? In Hodgson’s schema,
“effects of supply and demand on prices” are at the third level of abstraction,
that is, applicable to all civilized human societies. But surely one will want
to say that certain institutional facts about the monetary constitution will
affect the money-prices relation. But which ones? Is whether or not the gold
standard prevails relevant? Is the presence of e-banking? Do cultural
differences play a role? The point is that while Hodgson rightly alerts us that
economic laws hold only on account of a particular socio-economic structure, he
does not solve the problem of historical specificity. He does not tell us to
which degree and in what respects two socio-economic systems must resemble each
other for some economic law to hold in both systems. And I think there is a
good reason for this failure: there is no solution at the general level. All we
can say at the general level is that differences may matter but which ones
really do matter is an empirical question.
To summarize, Hodgson has done a great job in drawing attention to the fact
that economic laws are true only on account of particular arrangements of
institutional and cultural facts. He has written an exciting history of how
this matter has been treated in the economic literature from Marx to the
present day. Furthermore, he has presented us with elements of an analytical
framework that helps us to determine which kinds of institutions and cultural
facts may matter for which kinds of inquiry. In my view, his own methodological
framework cannot solve his original problem and it suffers from a slight bias
towards apriorism. Nonetheless, this book is greatly stimulating and I can
highly recommend it to anyone interested in economic history and methodology.
