Laforte. 0000006864 00000 n Its adoption as the backbone of the medium-scale models currently developed by many central banks and policy institutions is a clear re°ection of its success. That framework has also become the basis for the new generation of models being developed at central banks, and increasingly used for simulation and forecasting purposes.2 In the present chapter, I will try to summarize what I view as some of the key lessons that have emerged from that research program and to point to some of the challenges it faces, as well as possible ways of overcoming these challenges. In the New-Keynesian model, optimal interest rate policy under uncertainty is formulated without reference to monetary aggregates as long as certain standard assumptions on the dis-tributions of unobservables are satisfied.

Jordi Galí, 2017. 1 It has provided us with a framework that combines the theoretical rigor of Real Business Cycle (RBC) theory with Keynesian ingredients like monopolistic competition and nominal rigidities. Via the impact on risk taking, easy monetary policy lowers short-term downside risks to growth but increases medium-term risks. With rational private sector expectations about housing prices and inflation, optimal monetary policy can be characterized by a standard “target criterion” in terms of inflation and the output gap, that makes no reference to housing prices. %%EOF The model has been criticized for failing to explain Although the model is small with only three equations, it has some appealing properties: First, it is general equilibrium as the key variables concerned are endogenously determined. !�C�������#�)�, 3x8���"�E��G�ѣ9YzN]?�����;�L���noM��u�VdC����M�q�I����g1�o�nؠ�8��D���$l�>�`��Ş�]��J�d1"������@gVޏ��l��ʓ�>��I��B���'B2�;��EHr3IQ1%��f��館8���c�E�����9;族��A�ŧ�>� ���Xll�G6���6 Much of the research described in this paper is based on joint work with Olivier Blanchard, Rich Clarida, and Mark Gertler, who should get credit for all the valuable insights.
