| Abstract: | The applicability of complex systems theory in economics isevaluated and compared with standard approaches to economictheorising based upon constrained optimisation. A complex systemis defined in the economic context and differentiated from complexsystems in physio-chemical and biological settings. It is explainedwhy it is necessary to approach economic analysis from a network,rather than a production and utility function perspective, whenwe are dealing with complex systems. It is argued that muchof heterodox thought, particularly in neo-Schumpeterian andneo-Austrian evolutionary economics, can be placed within acomplex systems perspective upon the economy. The challengeis to replace prevailing ‘simplistic’ theories,based in constrained optimisation, with ‘simple’theories, derived from network representations in which valueis created through the establishment of new connections betweenelements. |
