This paper considers how the economics paradigm should be changed to e
mbrace modern concepts of systems science. It criticises the reduction
ist approaches of economic rationalism and free market economics and s
uggests a more holistic approach should be adopted, based on Prigogine
's concepts of dissipative structures, held in a state of tension far
from equilibrium; and Simon's concepts of sub optimisation. (C) 1998 J
