“Darwinian model
of economics flawed for firms”
“What
can the theory of evolution tell us about how the economy works? A lot. But
probably not what you think it does.
Famous economists
such as Joseph Schumpeter (author of the notion of ''creative destruction'')
and Milton Friedman, and the contemporary economic historian Niall Ferguson,
have viewed economies as Darwinian arenas: competition among firms reflects the
ruthless logic of natural selection. Firms struggle with each other, with
successful firms surviving and unsuccessful ones dying.
Thus evolution seems
to support three pillars of the conventional, neoclassical model of the
economy. First, that ''economic actors'' are self-interested, second, that
self-interest works to the good of the public (propelling Adam Smith's
''invisible hand'') and, third, that together these lead the market to deliver
the community ideal outcomes (''optimisation'').
But there's a basic fault
in this contention, as Dominic Johnson, of Oxford University, Michael Price, of
Britain's Brunel University, and Mark van Vugt, of Amsterdam's VU University,
point out in their paper, Darwin's
Invisible Hand.
In conventional
economics, ''economic actors'' can be either individuals or firms, although the
theory tends to treat firms as though they were individuals. In reality,
however, firms are groups of individuals - in the case of big national and
multinational companies, thousands of them in one firm.
So if Darwinian
selection applies to competitive markets, this implies that selection pressure
acts on groups, not individuals. And group selection, as opposed to
conventional Darwinian selection at the individual level, leads to the
emergence of traits that act against
self-interest.
With group
selection, ''we should expect the suppression of self-interest among
individuals, not its flourishing'', the authors say.
''Firms with less
self-interested workers will compete more effectively and spread at the expense
of firms with more self-interested workers, which will compete less effectively
and decline. In other words, the model predicts nasty firms but nice people.
Comment
I am not sure that the
authors of the paper Ross Gittins confronts (Dominic Johnson, of Oxford
University, Michael Price, of Britain's Brunel University, and Mark van Vugt,
of Amsterdam's VU University) really understand Darwinian evolution or its
application to the evolution of society, or to what its “ruthless logic”
amounts to. Evolution is neither
“benign” nor “ruthless” – it is moral free, blind and purposeless. It happens, usually over long time
periods. It is about constant change. Many sub-human species were
consequences of the speciation from the common ancestor of chimpanzees and the
hominine line 6-8 million years ago in East Africa, from which Homo sapiens eventually emerged
some 200,000 years ago.
All the pre-human
species in the line became extinct.
In biological evolution extinction is a regular and unpredictable
natural event. Nobody knows what fate awaits the human species, be it by
“nature” or by the ultimate ‘unintended consequence’ of “human actions”.
Once more on the
richness and boundaries of “self interest”: economists cling to the idea that
self-interest is egotistically competitive. It isn’t, at least in Adam Smith’s interpretation. No
individual can reach any level of self-interest without the co-operation of
many others, not all of them knowing or needing to know the ultimate beneficiaries
of their co-operation. So, as a very
young teenager (before discovering a much easier, quieter and cleaner, and
incidentally better paid job at £12 a week, on the Sydney Morning Herald) I
worked for £5.10s a weeks as an operator of a capstan-lathe, turning out dozens
of brass-fittings, drilled, scored and with threads to fit to some other
machined parts for something to do with I don’t know what. I never found out
what they were used for or who used them. But without those unknown people I would not have had
a job that satisfied my then self-interests of regular money. The price of that job was my
willingness to co-operate with anonymous others.
So it is in all
market societies. We cannot
serve our self-interests without mediating them with the self-interests of
others, as shown brilliantly in Smith’s “butcher, brewer and baker” example in
Wealth Of Nations (WN I.ii.2: 26-7). The myth of a self-interest ego is, well,
fantasy. True, my self-interest prompted me to move to the SMH, apart from the
pay and the cleanliness of the albeit untidy, air-conditioned proofreaders’
room. There were no early morning journeys to work (12 noon beats 6.50 am and
Sydney mornings at the beach beat sweaty mornings in a hot factory, in my
teenager’s view; also I had time to read a lot too, including much of the paper’s
contents, from which the idea formed of starting higher education in my early 20s).

read the full post. Ross Gittins
talks a lot of sense about Darwinian evolution and I am glad to see that the
Sydney Morning Herald appears to be in safe-hands, at least for economics and
evolution.
He only needs to forget modern theories of "propelling Adam Smith's ''invisible hand'' by reading Lost Legacy posts for a month or two - but, hey, let's be grateful for major steps towards agreement.
