Abstract: Much empirical analysis and econometric work recognizes that there are
nonlinearities, regime shifts or structural breaks, asymmetric adjustment costs,
irreversibilities and lagged dependencies. Hence, empirical work has already
transcended neoclassical economics. Some progress has also been made in modeling
endogenously generated cyclical growth and fluctuations. All this is inconsistent
with neoclassical general equilibrium. Hence there is growing evidence of Kuhnian
anomalies. It therefore follows that there is a Kuhnian crisis in economics and
further research in nonlinear dynamics and complexity can only increase the Kuhnian
anomalies. This crisis can only deepen. However, there is an ideological commitment
to general equilibrium that justifies free enterprise with only minimal state
intervention that may still sustain neoclassical economics despite the growing
evidence of Kuhnian anomalies. Thus, orthodox textbook theory continues to ignore
this fact and static neoclassical theory remains a dogma with no apparent
reformulation to replace it. Keywords: Kuhnian paradigm, neoclassical general equilibrium, nonlinear dymamics, chaos, complexity |
