Debortoli, Davide Kim, Jinill Lindé, Jesper Nunes, Ricardo central banks' objectives simple loss function monetary policy design sticky prices and sticky wages dsge models Macroeconomics and International Economics Yes, it makes a lot of sense. This paper studies how to design simple loss functions for central banks, as parsimonious approximations to social welfare. We show, both analytically and quantitatively, that simple loss functions should feature a high weight on measures of economic activity, sometimes even larger than the weight on inflation. Two main factors drive our result. First, stabilizing economic activity also stabilizes other welfare relevant variables. Second, the estimated model features mitigated inflation distortions due to a low elasticity of substitution between monopolistic goods and a low interest rate sensitivity of demand. The result holds up in the presence of measurement errors, with large shocks that generate a trade-off between stabilizing inflation and resource utilization, and also when ensuring a low probability of hitting the zero lower bound on interest rates. 2020-05-25T09:26:56Z 2020-05-25T09:26:56Z 2017-03-04 2020-05-25T09:25:12Z info:eu-repo/semantics/workingPaper Economics and Business Working Papers Series; 1560 L'accés als continguts d'aquest document queda condicionat a l'acceptació de les condicions d'ús establertes per la següent llicència Creative Commons http://creativecommons.org/licenses/by-nc-nd/3.0/es/ info:eu-repo/semantics/openAccess
