Alternative Framework For Economics
John Nightingale, (University

The award of the Nobel Prize in Economics for
Information Economics gives an opportunity
to illustrate why this form of economic analysis is a dead end. The theories
advanced by the
Prize winners, Akerlof, Stiglitz
and Spence, are ad hoc auxiliary assumptions tacked onto
the neoclassical, and neowalrasian, hard core. The
work of these auxiliaries is mainly ex
post rationalisation rather than prediction or explanation.
Is modern economic theory just a morass of special cases? It is important
alternative framework be found to allow valid generalisation to once again
economic theory, and this time, not fail to provide robust empirical results
in the absence
of ad hoc auxiliaries. Is there such
an alternative? We can report that
there is, and that it
promises all that is missing from orthodoxy.
The autism of
orthodoxy stems from its treatment of the human agent, who is mindless and
does not interact with other agents.
The broad solution then is to develop a framework in
which agents carry knowledge and interact with other agents to use and create
This is the essence of the new evolutionary economics (e.g. Loasby, Knowledge, Institutions
and Evolution in Economics, 1999).
In The New Evolutionary Microeconomics, Potts (2000)
argues that all heterodox thought shares a common ontological foundation in
the view that
the dynamics of evolving economic systems are in the space of
connections. An economy
is a complex system of interactions, and the dynamics of an economic system
change in the connective structure of the system. Three main themes can be
found to share
this common foundation.
The first is the evolutionary economics revived by Nelson and Winter
(1982). This builds on
Book IV of Marshall’s Principles, and on Schumpeter’s theories of
cycles and innovation,
creative destruction and greed for monopoly profit. Market capitalism is a
of experimentation in pursuit of sustainable rents based on private
knowledge. This is
fundamentally a neo-Darwinian approach.
It has been argued in Nightingale and Laurent
(Darwinism and Evolutionary Economics, Edward Elgar,
2001), that social and cultural
theory is ultimately swallowed by Darwin’s ‘universal acid’, as Dennett so
tellingly put it
(Dennett, Darwin’s Dangerous Idea, 1995). Complexity and self-organisation theory is
most recent advance of the neo-Darwinian project (Foster and Metcalfe, Frontiers
Evolutionary Economics, 2001).
The second is the New “Old Institutionalism”, which is about how agents with
construct and use complex systems of rules.
Current orthodoxy has largely ignored the
cognitive dimension of human behaviour.
This strand of course began with Veblen,
new life in the development of both evolutionary thought and its application
institutions. American Institutionalism saw the difficulties of Veblen’s imprecision and
contradictions, and neglected the biological metaphor introduced by Veblen in favour of a
vague developmental notion of institutions as historical determinants of
Current research on Veblen’s themes often ignores
his contribution, but continuity of ideas
remains clear. Organisational ecology,
and other resource and systems based views of the
firm, is one such well-defined field on inquiry. Evolutionary psychology is another (L.
Cosmides and J. Tooby,
(1994) ‘Better than Rational’ AER, 84:
327–32). Both these are
converging in the economist’s sphere, seeking explanations of selection
system regularities in habits, routines and the causes for organisations’ and
other institutions’ persistence as well as entry and exit. The means by
which knowledge is conserved as well as transformed and created is at the
centre of this program.
The third is the complex systems view of economic systems. Methodological
is one of the principles on which modern orthodox economics is based, as an
article of faith,
and a justification for the reductionism that has bedevilled areas such as
The antithesis of this is an organic approach that can be traced to, among
American pragmatist philosopher Charles Sanders Peirce. In essence, the concept of a
system rather than some atom within an aggregation of atoms, as the entity of
distinguishes the organic approach from MI.
Geoff Hodgson’s Economics and Evolution
(Polity Press, 1993) has an extended exposition of the importance of this
branch of theory.
Reductionism, one of the fundamentals of MI, insists on ‘micro foundations’
explanation. An organic, systems or
hierarchical approach insists that this demand is not
only irrelevant but misleading. Such a demand results in attempting to use
theory, and has long been abandoned in the physical and life sciences (ever
heard of a
sub-atomic theory of ocean waves?).
This range of heterodox economic theories, all of which are close relatives
of very orthodox
theories in other fields of science, are united against the neowalrasian orthodoxy, even with
