In the early 1970s, Robert E. Lucas Jr, developed an alternative theory of the Phillips curve and the money-driven business cycle, under the assumption of rational expectations. Lucas critique. Super exogeneity is always potentially refutable, and when both implications are involved, the Lucas critique is also refutable. A model that did not have that feedback would be ‘subject to the Lucas critique’. This historical appraisal clarifies how Lucas’s argument is currently understood and discussed within the dynamic stochastic general equilibrium (DSGE) approach. The Lucas critique, named for Robert Lucas's work on macroeconomic policymaking, argues that it is naive to try to predict the effects of a change in economic policy entirely on the basis of relationships observed in historical data, especially highly aggregated historical data. the Lucas critique could be seen as an attempt to explain a real-world phenomenon, the stagflation.

The Lucas critique states that every policy change affects the circumstances under which different situations occur. In conclusion, we point out that Lucas’s critique reveals a fundamental flaw in Lucas… Thus, a policy that worked under one set of circumstances may not apply under a different set.
