Other articles where Lucas critique is discussed: optimum currency area: The political renaissance of OCAs: According to the so-called Lucas critique (developed by the American economist Robert Lucas), rational economic agents anticipate and respond to policies; their behaviour, and therefore the “structure” of markets, cannot be taken as given. The critique is fundamental to modern macroeconomics, where statistical relationships across a number of economic variables are analysed and used to make policy-decisions, however the effectiveness and predictability of such methods is notoriously difficult to ascertain. Lucas’s critique of econometric models focuses on how parameters in policy rules may enter parametrically into economic agents’ optimization rules. That is, the Lucas critique has had a tremendous impact on macroeconomic theory and policy analysis. In the early 1970s, Robert E.

Lucas (1976) considers examples where agents’ expectations of policy behavior enter into their optimization problem, and so parameters relating to policymakers’ rules appear in the agents’ first-order conditions. The Lucas Critique has justified the micro-foundations approach to macroeconomics for four decades. I revisit the idea that this failure may be explained by models with indeterminate equilibria and I develop a class of expectations rules that I call generalized adaptive expectations.

We illustrate how the Lucas Critique was called into question by Keynesian macroeconomists during the 1970s and 1980s. Modern DSGE models are microfounded and have deep parameters that should be invariant to changes in economic policy, so in principle they are not subject to the Lucas critique. The paper shows why, in part, this goal has either, so far, eluded AU, its constitutive agencies, or its member states. Adaptive expectations imply systematic errors in forecasting and do not take account of other relevant information. Robert E. Lucas Jr. in private communication indicates that his primary concern was with the inaccuracy of the prevalent econometric models, and that he was not concerned at the time with the game theoretic distinction we make here. Critique (from here on: LC), in the Lucas (1976), for its applications is presented, followed by two sections “Framing the discussion” and “The great disconnect”.

Stephen Gordon writes that a key insight of behavioral economics is that people don’t always and everywhere re-optimize whenever their environments change. Robert Lucas was awarded the 1995 Nobel Prize in economics “for having developed and applied the hypothesis of rational expectations, and thereby having transformed macroeconomic analysis and deepened our understanding of economic policy.” More than any other person in the period from 1970 to 2000, Robert Lucas revolutionized macroeconomic theory. 0 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.
