The Lucas critique: a generalisation
*University of Cambridge
Abstract
The extraordinarily influential Lucas critique of various familiar econometric practices is generalised. The intention, though, is not to argue against the possibility of economics as science but to hasten its widespread realisation. To this end it is argued that a quite significant change of direction in economic practice is warrented, and an outline of a sustainable, potentially fruitful, alternative approach is indicated.
