We illustrate how the Lucas Critique was called into question by Keynesian macroeconomists during the 1970s and 1980s. The Lucas critique of econometric policy evaluation argues that it is inappropriate to esti-mate econometric models of the economy, in which endogenous variables appear as unrestricted functions of exogenous or predetermined variables, if one proposes to use such models for the purpose of evaluating alternative economic policies. 2 In fact, criticism of the Lucas critique has now become the subject of research agendas in its own right (Goutsmedt, Pinzon-Fuchs, Renault and Sergi, 2016). Super exogeneity is always potentially refutable, and when both implications are involved, the Lucas critique is also refutable. dy-namic stochastic general equilibrium (DSGE) models, are supposed to be the achievement of this quest for new approaches .

Our claim is that Keynesians’ reactions were carried out from a pragmatic approach, which addressed the empirical and practical relevance of the Critique. Though a great deal of ink has been spilled since the 1970s penning complicated, mathematical treatments of the Lucas Critique, its core claim is elegant in its simplicity: Now let us unpack the five key terms in that core claim: model, policy, policy variable, policy rule, and optimal.

This contribution to the history of the economic thought aims at describing how “Econometric Policy Evaluation: A Critique” (Lucas, 1976) has been interpreted through four decades of debates. The paper shows why, in part, this goal has either, so far, eluded AU, its constitutive agencies, or its member states.
