Uncertainty about the appropriate choice among nested models is a central concern for optimal policy when policy prescriptions from those models differ. The standard procedure is to specify a prior over the parameter space ignoring the special status of some sub-models, e.g. those resulting from...

This article assesses monetary policy's performances in the Euro zone in the face of supply shocks. We determine the responses of output, inflation, labor share and the nominal interest rate to a supply shock as identified through a structural VAR model. We then develop a DSGE model with nominal...

The first aim of the paper is to investigate a new source of economic stickiness, staggered nominal loan interest rate contracts between a private bank and a firm under the monopolistic competition. We introduce this staggered loan contract mechanism with micro-foundation based on agent's...

This paper considers the monetary policy implications of a model that features input-output connections between stages of production, so that a distinction between CPI inflation and PPI inflation arises. More specifically, this paper addresses the policy conclusion by K. Huang and Z. Liu [2005,...

We study optimal monetary policy in a two-sector model. The conventional wisdom in the literature is that the monetary authority should optimally stabilize inflation in the sticky-price sector. We reassess this issue in a two sector economy with capital accumulation subject to adjustment costs....

This paper deals with the implications of factor demand linkages for monetary policy design. We develop a dynamic general equilibrium model with two sectors that produce durable and non-durable goods, respectively. Part of the output produced in each sector is used as an intermediate input of...

Most New Keynesian models are derived under the assumption that inflation is equal to zero in the steady-state and yet most central banks around the world have inflation targets that are greater than such a number. In this paper we consider the open economy (welfare) implications of non-zero...

We study the implications for optimal monetary policy of introducing habit formation in consumption into a general equilibrium model with sticky prices. Habit formation affects the model's endogenous dynamics through its effects on both aggregate demand and households' supply of output. We show...

This paper studies optimal monetary policy with the nominal interest rate as the single policy instrument in an economy, where firms set prices in a staggered way without indexation and real money balances contribute separately to households' utility. The optimal deterministic steady state under...
