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. That is, the Lucas critique has had a tremendous impact on macroeconomic theory and policy analysis. 0 That is, the Lucas critique has had a tremendous impact on macroeconomic theory and policy analysis. 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. If monetary policy changes to become much harder on inflation, then rational agents will incorporate that into the way they form inflation expectations. 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. In the peasant-dictator game, there is a peasant who moves ﬁrst and must decide whether or not to undertake an investment: whether The Lucas Critique is a cautionary principle about relying on relationships in historical data. t,θ,u.

The ‘Lucas critique’ is a criticism of econometric policy evaluation procedures that fail to recognize that optimal decision rules of economic agents vary systematically with changes in policy. Put simply, unless you model the macro economy as a result of ‘deep parameters’ of the human psyche, you will never be sure whether your model will apply in a different regulatory or institutional environment. �B�T��NB|H��B�W*�~wNI�n_&8��ߝ��]F��p�I��$ 9�!� "�GB��H��Q�т��p�+��L��:�Ӽ��薑�^�^��qdc��q�1Pe��l&0�`�a�j)�}��+�ed�� Gtf^��כ��`p�fE��vG��4��N�~��}a��v[sH��~�4��k��-�y@��(��%��2��k�ȹ'�A�gś$ݝ�$NO+M�A�겨��7��j|}�pә�G�0v�Lo�b�N�P%$��ɲ��SC�� AP]��p�lm^П�=W�X0�� z�-�U��C��2��GIQ��s\4w>8G��E��5�+��b��Ÿ��Y��}.��Gֵ?P�H�v�U8��^��}VH�}'�Nܞs��xB�@-"Y�s�� c�\�k�o�V\a��M��9k��y��0VSSO��m��N��: 3 Smets and Wouters (2003, 1151) argue that their model is \very close to that of the best VAR models. t,θ,u.
