What is the Lucas critique Why does it matter?
The Lucas critique, named for American economist 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.
Which area of economics did Robert Lucas work in?
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 …

How should we apply the Lucas critique to macroeconomic modelling?
The Lucas critique has been and continues to be the cornerstone of modern macroeconomic modelling. In this note we apply the Lucas critique to macroeconomic modelling using deep rational expectations. In conclusion we point out that Lucas’ call for rational expectations models that provide useful economic policy advice has yet to be heeded.
Is the Lucas critique a positive or negative result?
The Lucas critique is, in essence, a negative result. It tells economists, primarily, how not to do economic analysis. The Lucas critique suggests that if we want to predict the effect of a policy experiment, we should model the “deep parameters” (relating to preferences, technology, and resource constraints)…
What are the microfoundations in the Lucas critique?
The Lucas critique suggests that if we want to predict the effect of a policy experiment, we should model the “deep parameters” (relating to preferences, technology, and resource constraints) that are assumed to govern individual behavior: so-called ” microfoundations .”. If these models can account for observed empirical regularities,…
Does the Lucas critique imply the use of the rational expectations hypothesis?
Lucas (1976) explicitly recognises that Jan Tinbergen and Jakob Marschak were aware of this problem since, at least, the 1940s. 3) The author considers that the Lucas Critique necessarily implies the use of the rational expectations hypothesis. Yet, a closer look at Lucas’s (1976) paper shows that this is not necessarily the case.
