In sticky price models with endogenous investment, virtually all monetary policy rules that set a nominal interest rate in response solely to future inʿation induce real indeterminacy of equilibrium. Applying the Samuelson-Farebrother conditions, we obtain a necessary and suffcient condition...

This paper studies the role of endogenous producer entry and product creation for monetary policy analysis and business cycle dynamics in a general equilibrium model with imperfect price adjustment. Optimal monetary policy stabilizes product prices, but lets the consumer price index vary to...

Two dynamic sticky price models with monopolistic competition in the goods market are presented. In the first model, each intermediate goods producer faces quadratic costs of adjusting its nominal price as introduced by Rotemberg (1982); the second model incorporates staggered price setting as...

This paper examines the role of habit persistence in consumption in explaining persistent responses of inflation and output to money growth shocks. A monetary stochastic dynamic general equilibrium (DGE) model with a money-in-the-utility-function (MIU-) setup is augmented by habit formation in...

We build quadratic labor adjustment costs into an otherwise standard New-Keynesian model of the business cycle and show that this increases output persistence in a similar vein as other models of labor market frictions. Furthermore, it is demonstrated that quadratic labor adjustment costs imply...
