Policy uncertainty, symbiosis, and the optimal fiscal and monetary conservativeness

  • Giovanni Di Bartolomeo


  • Francesco Giuli
  • Marco Manzo

This paper extends a well-known macroeconomic stabilization game between monetary and fiscal authorities introduced by Dixit and Lambertini (American Economic Review, 93: 1522-1542) to multiplicative (policy) uncertainty. We find that even if fiscal and monetary authorities share a common output and inflation target (i.e. the symbiosis assumption), the achievement of the common targets is no longer guaranteed; under multiplicative uncertainty, in fact, a time consistency problem arises unless policymakers� output target is equal to the natural level.
