Evolutionary economics
Based
on article from The FT, 18 January 2007
Eric
Beinhocker's book, The Origin of Wealth: Evolution, Complexity
and the Radical Remaking of Economics, published last year explains
to us 'why we are where we are today' in terms of evolutionary
economics. He shows how the world has evolved to be what we have
now through the complexity of the modern economy. He states "Yet
no one designed it and no one runs it". This idea of the
power of market forces is one that the late Milton Friedman emphasises
particularly in his TV series and book, Free To Choose. His famous
example being that not a single person in the world knows how
to make a pencil from the logging of the wood to the mining of
the metal and rubber on top. Only the hugely complex free market
can do this - there is no central direction where people make
certain orders in order for this pencil to be made.
In
the same way, Beinhocker shows how the economy has evolved in
a similar way to biological evolution. However, conventional economics
cannot go far in explaining this evolutionary process which has
taken 2.5 million years (of which most of the devlopment has happened
in the last 250 years). Whereas textbook economics assumes that
humans are rational, consistent beings, humans are prone to misjudgements
and mistakes. This evolutionary history, which Beinhocker explains
has equipped humans to survive in the rapidly changing world.
Much
of this evolutionary process depends on the use of finite resources
and human success in doing so has led to a great increase in wealth
and standard of living throughout the world including a huge increase
in world population.
Beinhockers
explains the evolutionary world in three ways: firstly through
physical technology which has enabled the the scientific and industrial
revolutions, secondly, the evolution of social technologies such
as money, democracy and markets and thirdly, the evolution of
businesses.
The
importance of markets in this evolutionary process is paramount
as they act as "innovation machines" because of the
power they have in effectiveness at innovation in disequilibrium.
