We examine the sources of macroeconomic economic fluctuations by estimating a variety of medium-scale DSGE models within a unified framework that incorporates regime switching both in shock variances and in the inflation target. Our general framework includes a number of different model features...

The possibility of regime shifts in monetary policy can have important effects on rational agents' expectation formation and equilibrium dynamics. In a dynamic stochastic general equilibrium model where the monetary policy rule switches between a dovish regime that accommodates inflation and a...

This paper reexamines the role of open market operations for short-run effects of monetary policy. Money demand is induced by a cash constraint, while the central bank supplies money exclusively in exchange for securities, discounted with a short-run nominal interest rate. We consider a legal...

In this paper an anti-cyclical fiscal policy rule is introduced into a dynamic stochastic general equilibrium model with New-Keynesian features. The rule allows the deficit to deviate from target in proportion to the impact of automatic stabilisers while any additional impact on the deficit, for...

What is the role of contracting schemes for the welfare costs of nominal rigidities over the business cycle? We examine 4 different modeling schemes of nominal rigidities that all have the same average duration of contracts. We find that Calvo (1983) wage and price contracts may deliver welfare...

In this paper we incorporate a labor market with matching frictions and wage rigidities into the New Keynesian business cycle model. In particular, we analyze the effect of a monetary policy shock and investigate how labor market frictions affect the transmission process of monetary policy. The...

We focus on a quantitative assessment of rigid labor markets in an environment of stable monetary policy. We ask how wages and labor market shocks feed into the inflation process and derive monetary policy implications. Towards that aim, we structurally model matching frictions and rigid wages...

The paper analyzes the dynamic effects of anticipated raw materials price increases for small open oil-dependent economies and investigates the consequences of several monetary policy rules in response to commodity price shocks. Based on a calibrated New Keynesian open economy model the analysis...

This paper studies the welfare effects of severalmonetary policy rules in the presence of anticipated and unanticipated oil price shocks. Our analysis is based on a stylized New Keynesian model of a small open economy. Our main findings are the following: i) Standard interest rate rules amplify...

The paper is concerned with determinacy in a version of the New-Keynesian model that integrates imperfect competition and nominal price and wage setting on goods and labour markets. The model is reformulated with an explicit period of arbitrary length and shown to remain well-defined as the...
